Since then, these little cubes have become a regular feature on our table, sometimes as a side dish to dinner, sometimes as a snack, and sometimes even as a sneaky addition to lunchboxes. They are just so incredibly versatile and easy to make, it’s almost embarrassing how little effort is required for such a big flavor and nutritional payoff.

Trust me, your family will thank you, and you’ll be patting yourself on the back for finding such an effortless winner.

Ingredients

The beauty of sweet potato cubes lies in their simplicity. You really don’t need a long list of fancy ingredients to create a dish that’s both delicious and satisfying. In fact, the core recipe uses just a handful of items, most of which you probably already have in your pantry. However, understanding each ingredient and its role can help you customize the recipe to your liking and ensure the best possible outcome. Let’s break down each component of our sweet potato cube recipe:

  • Sweet Potatoes: The star of the show, of course! When it comes to sweet potatoes, you have a few varieties to choose from, each with slightly different characteristics. The most common types you’ll find in grocery stores are often labeled as either “sweet potatoes” or “yams” – although, technically, what’s often sold as “yams” in the US are actually just another variety of sweet potato with a darker skin and more moist, orange flesh. For this recipe, either type will work beautifully. However, for a slightly drier and firmer cube that holds its shape exceptionally well after roasting, look for the varieties with lighter skin and pale yellow flesh. These tend to be less starchy and retain their texture better. Regardless of the type you choose, ensure your sweet potatoes are firm to the touch, without any soft spots or blemishes. The size of the sweet potatoes isn’t critical, but try to select ones that are relatively uniform in size so they cook at a similar rate. Organic sweet potatoes are always a great choice if available, but conventional ones will work just as well. Remember to wash your sweet potatoes thoroughly under cool running water, even if you plan to peel them, to remove any dirt or residue.
  • Olive Oil: A good quality olive oil is essential for roasting vegetables. It not only prevents the sweet potatoes from sticking to the baking sheet but also adds a subtle richness and flavor that complements the natural sweetness of the potatoes. Extra virgin olive oil is generally recommended for its superior flavor and health benefits, as it’s rich in antioxidants and healthy monounsaturated fats. When roasting at higher temperatures, some people prefer to use oils with a higher smoke point, like avocado oil or coconut oil. While these are perfectly acceptable alternatives, olive oil works wonderfully for roasting sweet potato cubes at the temperatures we’ll be using. If you’re concerned about the olive oil flavor being too strong, you can opt for a light olive oil or even a neutral-flavored oil like grapeseed oil. However, the subtle fruity notes of olive oil often enhance the overall taste of the roasted sweet potatoes beautifully. The amount of olive oil is also important; you want enough to lightly coat the sweet potato cubes so they roast evenly and develop a slightly crispy exterior, but not so much that they become greasy.
  • Salt: Salt is a crucial ingredient in almost any savory dish, and sweet potato cubes are no exception. Salt enhances the natural sweetness of the potatoes and balances the overall flavor profile. It also plays a role in drawing out moisture from the surface of the sweet potatoes, which helps them to caramelize and crisp up during roasting. Kosher salt or sea salt are excellent choices for this recipe. Kosher salt has a coarser grain that’s easy to pinch and distribute evenly, while sea salt offers a slightly more complex flavor. Table salt can also be used, but you may need to use slightly less as it’s more concentrated. The amount of salt is a matter of personal preference, but it’s important to season generously enough to bring out the flavors without making the cubes overly salty. Start with a moderate amount and taste after roasting to adjust if needed.
  • Black Pepper: Freshly ground black pepper adds a subtle warmth and spice that complements the sweetness of the sweet potatoes. It provides a nice contrast and depth of flavor that elevates the simple ingredients. While pre-ground pepper can be used, freshly ground pepper is always preferable for its brighter and more aromatic flavor. You can adjust the amount of black pepper to your liking, depending on your spice preference. A generous pinch is usually sufficient to enhance the flavor without being overpowering.

Optional Ingredients for Flavor Variations:

While the basic recipe is delicious on its own, sweet potato cubes are incredibly versatile and can be easily customized with various spices and herbs to create different flavor profiles. Here are a few optional ingredients you might consider adding to your sweet potato cubes to experiment with different tastes:

  • Spices: A pinch of cinnamon, nutmeg, or ginger can enhance the natural sweetness of the sweet potatoes and create a warm, comforting flavor, especially during the fall and winter months. For a slightly spicier kick, consider adding a dash of chili powder, cumin, or paprika. Smoked paprika can add a lovely smoky flavor that pairs beautifully with sweet potatoes. Garlic powder and onion powder are also great additions for a savory twist.
  • Herbs: Fresh or dried herbs can add a fresh and aromatic dimension to your sweet potato cubes. Rosemary, thyme, and sage are classic herbs that pair wonderfully with root vegetables like sweet potatoes. Dried herbs like oregano or Italian seasoning can also be used for a more Mediterranean-inspired flavor. If using fresh herbs, chop them finely and toss them with the sweet potato cubes before roasting or sprinkle them over the roasted cubes as a garnish.
  • Sweeteners (Optional): If you want to enhance the sweetness even further, you can drizzle a touch of maple syrup or honey over the sweet potato cubes before roasting. This will create a slightly caramelized and glazed exterior. Brown sugar is another option; you can toss the cubes with a sprinkle of brown sugar along with the olive oil and seasonings.
  • Lemon or Lime Juice: A squeeze of fresh lemon or lime juice after roasting can brighten up the flavors and add a touch of acidity that balances the sweetness. This is especially nice if you’ve added spices like chili powder or cumin.

By understanding the role of each ingredient and exploring different flavor combinations, you can create sweet potato cubes that are perfectly tailored to your taste preferences and dietary needs. The beauty of this recipe is its adaptability; feel free to experiment and find your favorite variations!

Instructions

Making sweet potato cubes is surprisingly straightforward, even for beginner cooks. The process is simple, requiring minimal equipment and just a few easy steps. Following these detailed instructions will ensure your sweet potato cubes turn out perfectly roasted, tender on the inside, and slightly crispy on the outside every time:

  1. Preheat Your Oven: The first and most crucial step is to preheat your oven to the correct temperature. For sweet potato cubes, a temperature of 400°F (200°C) is ideal. This high heat allows the sweet potatoes to roast quickly, caramelize beautifully, and develop a slightly crispy exterior while remaining tender on the inside. Make sure your oven is fully preheated before placing the sweet potato cubes inside; this will ensure even cooking and prevent them from steaming instead of roasting.
  2. Prepare the Sweet Potatoes: While the oven is preheating, it’s time to prepare your sweet potatoes.
    • Wash the Sweet Potatoes: Begin by thoroughly washing the sweet potatoes under cool running water. Use a vegetable brush to scrub away any dirt or soil clinging to the skin. Even if you plan to peel the sweet potatoes, washing them first is important to prevent transferring any dirt to the flesh during peeling.
    • Peel (Optional): Peeling sweet potatoes is optional for this recipe. The skin of sweet potatoes is perfectly edible and contains a good amount of fiber and nutrients. If you prefer a smoother texture or are not a fan of the skin, you can peel the sweet potatoes using a vegetable peeler. However, leaving the skin on will add a bit more texture and rustic appeal to the cubes. If you choose to leave the skin on, make sure to scrub them extra well during washing.
    • Cube the Sweet Potatoes: Now it’s time to cut the sweet potatoes into cubes. For even cooking, it’s important to cut the cubes into roughly uniform sizes. Aim for cubes that are about ¾ to 1 inch in size. Smaller cubes will cook faster and may become too crispy, while larger cubes may take longer to cook through and might not crisp up as well. To cube the sweet potatoes, first, cut them into slices lengthwise, then stack the slices and cut them into strips, and finally, cut the strips crosswise into cubes. A sharp chef’s knife will make this task easier and safer.
  3. Toss with Olive Oil and Seasonings: In a large bowl, combine the cubed sweet potatoes, olive oil, salt, and black pepper.
    • Add Olive Oil: Drizzle the olive oil over the sweet potato cubes. The amount of olive oil should be enough to lightly coat all the cubes. Start with about 2-3 tablespoons of olive oil for 2 medium-sized sweet potatoes and adjust as needed. You want the cubes to be lightly glistening with oil, but not swimming in it.
    • Season Generously: Sprinkle the salt and black pepper over the sweet potato cubes. Start with about ½ teaspoon of salt and ¼ teaspoon of black pepper for 2 medium sweet potatoes. You can adjust the seasoning to your taste. If you are using any optional spices or herbs, add them at this stage as well.
    • Toss to Coat: Use your hands or a large spoon to toss the sweet potato cubes with the olive oil and seasonings until they are evenly coated. Make sure every cube is lightly coated with oil and seasonings for optimal flavor and roasting.
  4. Arrange on a Baking Sheet: Spread the seasoned sweet potato cubes in a single layer on a baking sheet. It’s important to arrange them in a single layer and avoid overcrowding the pan. Overcrowding will cause the sweet potatoes to steam instead of roast, resulting in soggy cubes. If necessary, use two baking sheets to ensure they are spread out in a single layer. For easier cleanup, you can line the baking sheet with parchment paper or aluminum foil. This will also prevent the sweet potatoes from sticking to the pan.
  5. Roast in the Oven: Place the baking sheet in the preheated oven and roast for 20-25 minutes, or until the sweet potato cubes are tender and lightly browned.
    • Flip Halfway Through: About halfway through the roasting time, around 10-12 minutes, remove the baking sheet from the oven and flip the sweet potato cubes using a spatula. This will ensure even cooking and browning on all sides.
    • Check for Doneness: To check if the sweet potatoes are done, pierce a cube with a fork. It should be easily pierced and tender throughout. The edges should be slightly caramelized and golden brown. If they are not tender enough, continue roasting for another 5-10 minutes, checking for doneness every few minutes. Roasting time may vary slightly depending on the size of the cubes and your oven.
  6. Cool Slightly and Serve: Once the sweet potato cubes are roasted to perfection, remove the baking sheet from the oven and let them cool slightly for a few minutes before serving. This will allow them to firm up a bit and make them easier to handle. Serve them hot as a side dish, snack, or as part of a larger meal.

Following these detailed instructions will guide you through each step of making delicious roasted sweet potato cubes. Remember to adjust the seasoning and roasting time to your preferences and oven, and don’t be afraid to experiment with different flavor variations to create your own signature sweet potato cube recipe!

Time-Saving Tips:

  • Pre-cut Sweet Potatoes (Sometimes): Some grocery stores sell pre-cut sweet potato cubes in the produce section. While this can save you prep time, they may be more expensive and might not be as fresh as cutting them yourself. Also, ensure they are cut into reasonably uniform sizes.
  • Peel Ahead of Time: If you prefer peeled sweet potatoes, you can peel them a day or two in advance and store them submerged in water in the refrigerator to prevent browning. Drain and cube them just before roasting.
  • Minimal Ingredients: The simplicity of the recipe itself is a time-saver. Using just a few basic ingredients means less time spent gathering and measuring.
  • Efficient Cubing Technique: Practice your knife skills to cube the sweet potatoes more efficiently. Using a sharp knife and a stable cutting board will make the process faster and safer.

Make-Ahead Options:

While roasted sweet potato cubes are best served fresh and warm, you can do some prep work in advance to save time on the day you plan to serve them.

  • Prepare the Cubes Ahead: You can wash, peel, and cube the sweet potatoes up to a day in advance. Store the cubed sweet potatoes in an airtight container filled with cold water in the refrigerator to prevent browning. Drain them thoroughly and pat them dry with paper towels before tossing with oil and seasonings and roasting.
  • Season Ahead (Up to a Few Hours): You can toss the cubed sweet potatoes with olive oil and seasonings a few hours before roasting and keep them covered in the refrigerator. This can allow the flavors to meld slightly. However, it’s best to roast them as soon as possible after seasoning for the best texture.

While you can technically reheat roasted sweet potato cubes, they are at their best when freshly roasted. Reheating may make them slightly softer. Therefore, it’s recommended to roast them closer to serving time for optimal taste and texture.

Overall, the quick preparation time of sweet potato cubes makes them an ideal choice for a healthy and delicious side dish or snack, even when you’re short on time.

Additional Tips

To ensure your sweet potato cubes are consistently delicious and perfectly roasted every time, here are five additional tips to keep in mind:

  1. For Extra Crispy Cubes, Roast at a Higher Temperature: If you prefer your sweet potato cubes to be extra crispy on the outside, you can increase the oven temperature to 425°F (220°C). Roasting at a higher temperature will promote more browning and crisping. However, keep a close eye on them to prevent burning, especially if your oven tends to run hot. You may also need to reduce the roasting time slightly when using a higher temperature.
  2. Consider Soaking for Enhanced Crispness: For truly crispy sweet potato cubes, consider soaking them in cold water for about 30 minutes before roasting. Soaking helps to remove excess starch from the surface of the potatoes, which can contribute to sogginess. After soaking, drain them thoroughly and pat them completely dry with paper towels before tossing with olive oil and seasonings. Dry sweet potatoes are crucial for achieving crispiness.
  3. Don’t Overcrowd the Baking Sheet: This is a critical tip for achieving perfectly roasted vegetables in general, and sweet potato cubes are no exception. Make sure to spread the cubes in a single layer on the baking sheet, leaving some space between them. Overcrowding will cause them to steam instead of roast, resulting in soggy and unevenly cooked cubes. If necessary, use two baking sheets to avoid overcrowding.
  4. Experiment with Seasoning Variations: While salt and pepper are essential, don’t be afraid to experiment with different seasoning combinations to create various flavor profiles. Try adding spices like cinnamon, nutmeg, or ginger for a warmer, sweeter flavor, or chili powder, cumin, or paprika for a spicier, savory kick. Herbs like rosemary, thyme, or oregano also pair wonderfully with sweet potatoes. Consider sweetening them up with a drizzle of maple syrup or honey before roasting, or adding a squeeze of lemon or lime juice after roasting to brighten the flavors.
  5. Store Leftovers Properly and Reheat for Best Results: While freshly roasted sweet potato cubes are always best, leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat them and retain some crispiness, spread them in a single layer on a baking sheet and reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through. You can also reheat them in an air fryer for a quicker and crispier result. Microwaving is also an option for reheating, but it will make them softer and less crispy.

By following these additional tips, you can consistently create delicious, perfectly roasted sweet potato cubes that are crispy, flavorful, and a hit with everyone!

FAQ Section

Here are some frequently asked questions about making sweet potato cubes to help you troubleshoot and get the best results:

Q1: Can I use different types of sweet potatoes for this recipe?

A: Yes, absolutely! While the recipe generally works well with most common types of sweet potatoes (including those often labeled as “yams”), you can experiment with different varieties. Varieties with drier flesh, like those with lighter skin and pale yellow flesh, tend to roast up slightly firmer and less mushy. However, orange-fleshed sweet potatoes will also work beautifully and will be slightly sweeter and more moist. Feel free to use whatever type of sweet potato you prefer or have available.

Q2: Can I cook sweet potato cubes in an air fryer?

A: Yes, air frying is a fantastic method for cooking sweet potato cubes and achieving extra crispiness in less time. Preheat your air fryer to 400°F (200°C). Toss the sweet potato cubes with olive oil and seasonings as instructed in the recipe. Arrange them in a single layer in the air fryer basket (you may need to cook in batches to avoid overcrowding). Air fry for 12-15 minutes, shaking the basket or flipping the cubes halfway through, until tender and crispy. Air frying typically takes less time than oven roasting, so keep an eye on them to prevent burning.

Q3: How do I prevent my sweet potato cubes from getting soggy?

A: Soggy sweet potato cubes are often a result of overcrowding the baking sheet, not drying them properly after washing or soaking, or not roasting at a high enough temperature. Ensure you spread the cubes in a single layer on the baking sheet, leaving space between them. Pat them completely dry after washing or soaking before tossing with oil and seasonings. Roast at 400°F (200°C) or even 425°F (220°C) for extra crispiness. Soaking them in cold water for 30 minutes before roasting and then drying them thoroughly can also help remove excess starch and promote crispiness.

Q4: Can I make sweet potato cubes ahead of time?

A: While freshly roasted sweet potato cubes are best, you can prepare them in advance to save time. You can wash, peel, and cube the sweet potatoes up to a day ahead and store them submerged in water in the refrigerator. You can also toss them with olive oil and seasonings a few hours before roasting and keep them refrigerated. However, for the best texture and flavor, it’s recommended to roast them closer to serving time. Leftover roasted sweet potato cubes can be stored in the refrigerator for 3-4 days and reheated.

Q5: Are sweet potato cubes healthy?

A: Yes, sweet potato cubes are a very healthy snack or side dish! They are packed with nutrients, including Vitamin A (from beta-carotene), Vitamin C, fiber, potassium, and antioxidants. They are relatively low in calories and fat, especially when roasted with a moderate amount of olive oil. Sweet potatoes are a complex carbohydrate source, providing sustained energy. They are a much healthier alternative to processed snacks like chips or fries and contribute valuable nutrients to your diet. Enjoy them as a guilt-free and nutritious addition to your meals!

    • Toss to Coat: Use your hands or a large spoon to toss the sweet potato cubes with the olive oil and seasonings until they are evenly coated. Make sure every cube is lightly coated with oil and seasonings for optimal flavor and roasting.

  4. Arrange on a Baking Sheet: Spread the seasoned sweet potato cubes in a single layer on a baking sheet. It’s important to arrange them in a single layer and avoid overcrowding the pan. Overcrowding will cause the sweet potatoes to steam instead of roast, resulting in soggy cubes. If necessary, use two baking sheets to ensure they are spread out in a single layer. For easier cleanup, you can line the baking sheet with parchment paper or aluminum foil. This will also prevent the sweet potatoes from sticking to the pan.
  5. Roast in the Oven: Place the baking sheet in the preheated oven and roast for 20-25 minutes, or until the sweet potato cubes are tender and lightly browned.

    • Flip Halfway Through: About halfway through the roasting time, around 10-12 minutes, remove the baking sheet from the oven and flip the sweet potato cubes using a spatula. This will ensure even cooking and browning on all sides.
    • Check for Doneness: To check if the sweet potatoes are done, pierce a cube with a fork. It should be easily pierced and tender throughout. The edges should be slightly caramelized and golden brown. If they are not tender enough, continue roasting for another 5-10 minutes, checking for doneness every few minutes. Roasting time may vary slightly depending on the size of the cubes and your oven.

  6. Cool Slightly and Serve: Once the sweet potato cubes are roasted to perfection, remove the baking sheet from the oven and let them cool slightly for a few minutes before serving. This will allow them to firm up a bit and make them easier to handle. Serve them hot as a side dish, snack, or as part of a larger meal.
