Ingredients

This recipe is thoughtfully composed to balance flavour and texture. You’ll find a mix of pantry staples and fresh produce, readily available at most grocery stores. Let’s break down what you’ll need to create this vegetarian masterpiece:

For the Savoury Lentil and Vegetable Filling:

• 1 tablespoon olive oil: Forms the base for sautéing and adds healthy fats.
• 1 large onion, chopped: Provides a foundational aromatic flavour base.
• 2 carrots, diced: Adds sweetness, texture, and vibrant colour to the filling.
• 2 celery stalks, diced: Contributes a subtle savory note and aromatic depth.
• 2 cloves garlic, minced: Essential for that pungent, savoury garlic flavour.
• 1 cup green lentils, rinsed: The heart of the filling, providing protein and a hearty texture. Green lentils hold their shape well during cooking.
• 1 cup vegetable broth: The liquid base for simmering the lentils and vegetables, adding flavour and moisture. Opt for low-sodium to control salt content.
• 1 (14.5 ounce) can diced tomatoes, undrained: Adds acidity, sweetness, and liquid to the filling, creating a rich sauce.
• 1 teaspoon dried thyme: Lends an earthy, herbaceous aroma and flavour that complements the lentils and vegetables.
• 1 teaspoon dried rosemary: Adds a piney, slightly pungent note, enhancing the savoury profile.
• 1/2 teaspoon smoked paprika: Provides a subtle smoky depth and warmth, enhancing the overall flavour complexity.
• 1/4 teaspoon red pepper flakes (optional): For a gentle kick of heat, adjust to your spice preference or omit for a milder version.
• 1 tablespoon tomato paste: Concentrates tomato flavour and adds richness and depth to the sauce.
• 1 tablespoon Worcestershire sauce (vegetarian or vegan, check label): Adds umami and savoury depth. Ensure you use a vegetarian or vegan version, as traditional Worcestershire sauce contains anchovies. Soy sauce or tamari can be substituted for a vegan option.
• 1 cup frozen peas: Added towards the end for a burst of sweetness, colour, and freshness.
• Salt and freshly ground black pepper to taste: Essential for seasoning and balancing all the flavours.

For the Sweet Potato Topping:

• 2 large sweet potatoes (about 1.5 pounds total), peeled and cubed: The star of the topping, providing sweetness, creaminess, and vibrant colour.
• 1/4 cup milk (dairy or non-dairy, such as almond or oat): Adds moisture and creaminess to the mashed sweet potato. Use your preferred milk.
• 2 tablespoons butter (dairy or vegan butter substitute): Adds richness, flavour, and helps create a smooth, creamy texture. Vegan butter works perfectly for a vegan version.
• 1/4 teaspoon ground nutmeg: A warm, slightly sweet spice that beautifully complements sweet potato, enhancing its flavour.
• Salt and freshly ground black pepper to taste: Seasoning the sweet potato is crucial to balance the sweetness and savoury filling.
• 2 tablespoons grated Parmesan cheese (optional, vegetarian or vegan alternative): Adds a slightly salty, nutty flavour and a golden crust when baked. Omit for vegan or use nutritional yeast for a vegan cheesy flavour.

Instructions

This recipe is broken down into easy-to-follow steps, ensuring a smooth cooking process and a delicious final product. Follow these instructions carefully to create your own perfect Vegetarian Cottage Pie with Sweet Potato topping:

Getting Started: Preparing the Sweet Potato Topping

1. Preheat your oven to 400°F (200°C). This ensures the oven is ready to bake the cottage pie once assembled.
2. Prepare the sweet potatoes: Place the peeled and cubed sweet potatoes in a medium saucepan and cover them with cold water. Add a pinch of salt. Bring to a boil over high heat, then reduce heat to medium-low and simmer for 15-20 minutes, or until the sweet potatoes are fork-tender. Boiling until tender ensures they mash smoothly and easily.
3. Drain and mash the sweet potatoes: Once tender, drain the sweet potatoes thoroughly. Return them to the saucepan and mash them with a potato masher or a fork until smooth.
4. Enhance the sweet potato mash: Stir in the milk, butter, nutmeg, salt, and pepper to the mashed sweet potatoes. Mix until well combined and creamy. Set aside while you prepare the filling. Taste and adjust seasoning as needed. The warm milk and butter will help create a smooth and flavourful topping.

Creating the Savoury Lentil and Vegetable Filling:

5. Sauté the aromatics: Heat the olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Sauté for 5-7 minutes, or until the vegetables begin to soften and the onion becomes translucent. Stir occasionally to prevent sticking and ensure even cooking.
6. Add garlic and spices: Add the minced garlic, dried thyme, dried rosemary, smoked paprika, and red pepper flakes (if using) to the skillet. Sauté for another minute, until fragrant. Stirring the spices in oil releases their aroma and flavour.
7. Incorporate lentils and liquids: Add the rinsed green lentils, vegetable broth, diced tomatoes (undrained), tomato paste, and Worcestershire sauce (or soy sauce/tamari) to the skillet. Stir well to combine all ingredients.
8. Simmer the filling: Bring the mixture to a simmer, then reduce heat to low, cover, and simmer for 25-30 minutes, or until the lentils are tender but still slightly firm, and the sauce has thickened. Stir occasionally to prevent sticking and ensure even cooking of the lentils. Check for liquid level and add a little more broth if it becomes too dry.
9. Stir in peas and season: Remove the skillet from the heat and stir in the frozen peas. The residual heat will cook the peas perfectly, keeping them bright green and slightly sweet. Season the filling generously with salt and freshly ground black pepper to taste. Adjust seasoning as needed; taste is crucial at this stage.

Assembling and Baking the Vegetarian Cottage Pie:

10. Preheat oven to 375°F (190°C). Reduce oven temperature slightly for baking the assembled pie.
11. Top with sweet potato mash: Evenly spread the mashed sweet potato topping over the lentil and vegetable filling in the skillet. Ensure the topping reaches the edges of the skillet to create a sealed crust.
12. Optional cheese topping: If using, sprinkle the grated Parmesan cheese (or vegan alternative/nutritional yeast) evenly over the sweet potato topping. This will create a golden, slightly crispy crust.
13. Bake the cottage pie: Bake in the preheated oven for 20-25 minutes, or until the sweet potato topping is heated through, lightly golden brown on top, and the filling is bubbly around the edges. Baking until golden ensures the topping is cooked and slightly caramelized.
14. Rest before serving: Remove from the oven and let the cottage pie rest for 5-10 minutes before serving. This allows the filling to settle slightly and makes it easier to serve.

How to Serve

Vegetarian Cottage Pie with Sweet Potato is a complete meal in itself, but it pairs beautifully with a variety of side dishes to create a more elaborate and balanced dinner. Here are some serving suggestions:

• Fresh Green Salad:
  • A simple salad with mixed greens, a light vinaigrette, and perhaps some cherry tomatoes or cucumber provides a refreshing contrast to the richness of the cottage pie.
  • Consider adding a sprinkle of toasted nuts or seeds for extra texture and nutrition.
• Steamed Green Vegetables:
  • Steamed broccoli, green beans, or asparagus offer a healthy and vibrant side.
  • A squeeze of lemon juice or a drizzle of olive oil enhances their flavour.
• Crusty Bread:
  • Serve with warm, crusty bread or rolls for soaking up the delicious sauce.
  • Garlic bread or sourdough would be particularly delightful.
• Roasted Root Vegetables (Different from the Pie):
  • While the pie has carrots and sweet potato, roasting other root vegetables like parsnips, turnips, or beets can add variety and complementary flavours.
  • Season them simply with herbs and olive oil.
• Pickled Vegetables:
  • A side of pickled vegetables, like gherkins or pickled onions, can offer a tangy counterpoint to the richness of the pie.
• Chutney or Relish:
  • A dollop of chutney or relish, such as apple chutney or tomato relish, can add a touch of sweetness and complexity.

Serving Suggestions for Different Occasions:

• Weeknight Dinner: Serve as is for a comforting and easy weeknight meal. A simple green salad is sufficient as a side.
• Weekend Family Gathering: Pair with a larger green salad, steamed green vegetables, and crusty bread for a more substantial and celebratory meal.
• Potluck or Bring-a-Dish: This cottage pie is perfect for potlucks as it travels well and is always a crowd-pleaser. It can be made ahead and reheated.
• Vegetarian Thanksgiving or Holiday Meal: A fantastic vegetarian main course option for holidays, offering a hearty and flavourful alternative to traditional meat-centric dishes.

Additional Tips for the Perfect Vegetarian Cottage Pie

To ensure your Vegetarian Cottage Pie is a resounding success, here are five helpful tips to keep in mind:

1. Don’t Overcook the Lentils: Keep an eye on the lentils while they simmer. You want them to be tender but not mushy. Overcooked lentils will lose their texture and the filling might become too soft. They should retain a slight bite when cooked.
2. Taste and Season as You Go: Seasoning is key to a flavourful dish. Taste the filling at various stages – after sautéing the vegetables, after adding the lentils and liquids, and finally before topping with sweet potato. Adjust salt, pepper, and spices as needed to achieve a balanced and delicious flavour profile.
3. Make it Ahead for Convenience: The lentil filling can be made a day or two ahead of time and stored in the refrigerator. You can also mash the sweet potatoes in advance. Assemble and bake the cottage pie just before serving for a stress-free meal, especially helpful for busy weeknights or entertaining.
4. Customize Your Vegetables: Feel free to adapt the vegetable filling to your liking or what you have on hand. Mushrooms, bell peppers, zucchini, or corn kernels would all be delicious additions. Get creative and use seasonal vegetables for variety and flavour.
5. Achieve a Golden Topping: For a beautifully browned and slightly crispy sweet potato topping, you can broil the cottage pie for the last few minutes of baking. Keep a close eye on it to prevent burning. Alternatively, brushing the sweet potato topping with a little melted butter or olive oil before baking can also enhance browning.

Frequently Asked Questions (FAQ)

Here are some common questions you might have about making Vegetarian Cottage Pie with Sweet Potato:

Q1: Can I make this recipe vegan?
A: Yes, absolutely! To make this recipe vegan, simply make a few easy substitutions. Use vegan butter for the sweet potato topping, ensure your Worcestershire sauce is vegan (or use soy sauce or tamari instead), and omit the Parmesan cheese topping or use a vegan Parmesan alternative or nutritional yeast for a cheesy flavour. Use non-dairy milk like almond, oat, or soy milk for the sweet potato mash.

Q2: Can I use red lentils instead of green lentils?
A: While green lentils are recommended for their texture, you can use red lentils in a pinch. However, red lentils tend to cook down more and become softer, potentially resulting in a less textured filling. If using red lentils, reduce the simmering time and be mindful of the consistency. You might need to add less liquid.

Q3: Can I freeze Vegetarian Cottage Pie?
A: Yes, Vegetarian Cottage Pie freezes very well. Assemble the pie in a freezer-safe dish but do not bake it. Cover tightly with plastic wrap and then foil. Freeze for up to 3 months. To bake from frozen, thaw overnight in the refrigerator or bake directly from frozen (covered with foil) at 350°F (175°C) for about 1.5-2 hours, or until heated through and bubbly. Remove foil for the last 20-30 minutes to brown the topping.

Q4: I don’t have sweet potatoes, can I use regular potatoes for the topping?
A: Yes, you can substitute regular potatoes for the sweet potato topping. Yukon Gold or Russet potatoes work well for mashing. The flavour will be different, less sweet and more traditionally “cottage pie” like, but still delicious. Follow the same instructions for boiling, mashing, and seasoning the potatoes.

Q5: Can I add other vegetables to the filling?
A: Definitely! Feel free to customize the vegetable filling to your preferences. Mushrooms, bell peppers, zucchini, corn, peas, or even chopped spinach or kale can be added. Consider sautéing heartier vegetables with the onions and carrots, and adding leafy greens towards the end of cooking, similar to the peas.

This Vegetarian Cottage Pie with Sweet Potato is more than just a recipe; it’s an invitation to embrace plant-based comfort food that’s both satisfying and nourishing. Enjoy the process of creating this delicious meal and sharing it with loved ones!
