Ingredients
- Eggs: The foundation of our quiche, eggs provide structure, richness, and protein. You’ll need 8 large eggs for a standard 9-inch pie dish. For a richer, more decadent quiche, you can use a combination of whole eggs and egg yolks (e.g., 6 whole eggs and 2-4 yolks). If you are looking for an egg substitute due to allergies or dietary preferences, unfortunately, achieving the same texture and binding in a crustless quiche without eggs is very challenging. Egg replacers often don’t provide the necessary structure for a quiche to set properly. This recipe is primarily designed around eggs as the binding agent.
- Dairy-Free Milk: To create the creamy custard base without dairy, we’ll use plant-based milk. 1 cup of unsweetened, plain dairy-free milk is ideal. Excellent options include:
- Almond Milk: Adds a subtle nutty flavor and is readily available. Choose unsweetened to avoid unwanted sweetness in your quiche.
- Cashew Milk: Known for its creamy texture, cashew milk creates a richer and smoother custard. Again, opt for unsweetened and plain.
- Oat Milk: Naturally slightly sweet and creamy, oat milk is another great choice. Unsweetened and plain varieties are recommended.
- Soy Milk: A classic dairy-free alternative, soy milk is versatile and works well in savory dishes. Unsweetened and plain is best.
- Coconut Milk (Light): While full-fat coconut milk can be too overpowering in flavor and richness for a vegetable quiche, light coconut milk can add a subtle sweetness and creaminess. Use it sparingly or in combination with another plant-based milk for a balanced flavor. Avoid sweetened coconut milk.
- Vegetables (Approximately 3-4 cups total, chopped): This is where you can get creative and use your favorite garden bounty! Aim for a colorful and diverse mix of textures and flavors. Consider these options:
- Onions and Garlic: Aromatic base flavors are crucial. Use 1 medium onion, chopped (yellow, white, or red onion all work) and 2-3 cloves of garlic, minced. Sautéing these first will mellow their sharpness and enhance their sweetness.
- Bell Peppers: Add sweetness and vibrant color. Use 1-2 bell peppers, any color (red, yellow, orange, green). Remove seeds and membranes and chop them into bite-sized pieces.
- Broccoli or Cauliflower: Cruciferous vegetables add substance and nutritional value. Use 1-2 cups of broccoli or cauliflower florets, chopped into small, even pieces. Lightly steam or blanch them before adding to the quiche to ensure they are tender in the final dish.
- Zucchini or Summer Squash: Mild and tender, these squashes add moisture and lightness. Use 1-2 medium zucchini or summer squash, diced. No need to peel unless the skin is very thick.
- Spinach or Kale: Leafy greens bring in essential vitamins and minerals. Use 2-3 cups of fresh spinach or kale, roughly chopped. Spinach can be added directly, while kale may benefit from a quick sauté or massage to soften it slightly.
- Mushrooms: Earthy and savory, mushrooms add depth of flavor. Use 1-2 cups of sliced mushrooms (cremini, button, shiitake, or a mix). Sauté them to release their moisture and concentrate their flavor.
- Asparagus: Adds a delicate, slightly grassy flavor and spring-like touch. Use 1 bunch of asparagus, trimmed and cut into 1-inch pieces. Blanching or roasting briefly enhances their tenderness.
- Tomatoes (Cherry or Roma): Add juicy bursts of sweetness and acidity. Use 1 cup of cherry tomatoes, halved or 1-2 Roma tomatoes, diced. Consider roasting them briefly to intensify their flavor.
- Corn (Fresh or Frozen): Adds sweetness and a pleasant pop of texture. Use 1 cup of fresh or frozen corn kernels. If using frozen, thaw them first.
- Peas (Fresh or Frozen): Another sweet and tender vegetable that adds a vibrant green color. Use 1 cup of fresh or frozen peas. If using frozen, thaw them first.
- Nutritional Yeast: This is a key ingredient for achieving a “cheesy” flavor in a dairy-free quiche. 2-3 tablespoons of nutritional yeast will provide a savory, umami richness that mimics the taste of cheese. Don’t skip this!
- Fresh Herbs (Optional but Recommended): Herbs elevate the flavor profile and add freshness. Use 2-3 tablespoons of chopped fresh herbs, such as:
- Chives: Mild oniony flavor, great for garnish and throughout the quiche.
- Parsley (Italian or Curly): Fresh and clean flavor, versatile and complements most vegetables.
- Thyme: Earthy and slightly lemony, adds warmth and depth.
- Rosemary: Piney and aromatic, use sparingly as it can be strong. Pairs well with heartier vegetables like mushrooms and potatoes (if you choose to add them – though potatoes are less typical in a garden vegetable quiche).
- Basil: Sweet and peppery, especially good with tomatoes and zucchini.
- Oregano: Earthy and slightly pungent, adds Mediterranean notes.
- Spices and Seasonings: Essential for bringing out the flavors.
- Salt and Black Pepper: To taste. Start with ¾ teaspoon of salt and ½ teaspoon of black pepper and adjust as needed.
- Garlic Powder or Onion Powder (Optional): Adds another layer of savory depth. ½ teaspoon of each is a good starting point.
- Red Pepper Flakes (Optional): For a touch of heat. ¼ teaspoon or to taste.
- Dried Herbs (If not using fresh): If you don’t have fresh herbs, use 1-2 teaspoons of dried herbs (e.g., dried thyme, oregano, or Italian seasoning blend).
- Olive Oil or Avocado Oil: For sautéing the vegetables. 2-3 tablespoons should be sufficient. Olive oil adds a classic Mediterranean flavor, while avocado oil is neutral and has a high smoke point.
Instructions
- Preheat Oven and Prepare Baking Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish with olive oil or cooking spray. A ceramic or glass pie dish works best for even baking.
- Prepare the Vegetables: This is a crucial step to ensure your vegetables are tender and flavorful in the quiche.
- Chop all your vegetables into bite-sized pieces. Aim for relatively uniform sizes so they cook evenly.
- Sauté Aromatics: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onions and sauté for 3-5 minutes until softened and translucent. Add the minced garlic and sauté for another minute until fragrant, being careful not to burn the garlic.
- Sauté Heartier Vegetables: Add the bell peppers, broccoli/cauliflower, mushrooms, and zucchini/summer squash (or any other heartier vegetables you are using) to the skillet. Sauté for 5-7 minutes until they are slightly softened but still have a bit of bite. You don’t want them to be fully cooked at this stage as they will continue to cook in the oven.
- Add Leafy Greens (Optional): If using kale, add it to the skillet in the last 2-3 minutes of sautéing to soften slightly. Spinach can be added directly to the egg mixture without sautéing, as it wilts quickly in the oven.
- Season Vegetables: Season the sautéed vegetables with salt, black pepper, garlic powder/onion powder (if using), and red pepper flakes (if using). Taste and adjust seasonings to your liking.
- Set Aside to Cool Slightly: Remove the skillet from the heat and set the sautéed vegetables aside to cool slightly while you prepare the egg mixture. This prevents the hot vegetables from partially cooking the eggs when you combine them.
- Prepare the Egg Mixture: In a large bowl, whisk together the 8 large eggs, 1 cup of dairy-free milk, and 2-3 tablespoons of nutritional yeast. Whisk vigorously until the mixture is well combined and slightly frothy. This incorporates air and helps create a lighter texture. Season the egg mixture with salt and black pepper to taste. Remember that the vegetables are also seasoned, so adjust accordingly.
- Assemble the Quiche:
- Arrange Vegetables in Pie Dish: Spread the sautéed vegetables evenly in the prepared pie dish. You can create a slightly mounded layer, but avoid overfilling the dish, as you need space for the egg mixture.
- Pour Egg Mixture Over Vegetables: Gently pour the egg mixture over the vegetables in the pie dish, ensuring it distributes evenly and reaches all the vegetables.
- Add Fresh Herbs (Optional): Sprinkle the chopped fresh herbs (chives, parsley, thyme, basil, oregano, rosemary) evenly over the top of the quiche.
- Bake the Quiche:
- Bake in Preheat Oven: Place the pie dish in the preheated oven and bake for 40-50 minutes, or until the quiche is set and lightly golden brown on top. The center should be just set – it should jiggle slightly but not be liquidy.
- Check for Doneness: To check if the quiche is done, gently insert a knife or toothpick into the center. It should come out mostly clean, with perhaps a few moist crumbs but no liquid egg.
- Rotate Dish (Optional): Rotating the pie dish halfway through baking can help ensure even browning.
- Cool and Serve:
- Let Cool Slightly: Remove the quiche from the oven and let it cool in the pie dish for at least 10-15 minutes before slicing and serving. This allows the quiche to set further and makes it easier to slice.
- Slice and Serve: Slice the quiche into wedges and serve warm or at room temperature. It’s delicious on its own or with a side salad.
