Step‑by‑Step Instructions for Crustless Garden Vegetable Quiche
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) while greasing a pie dish or quiche pan with ghee or avocado oil to prevent sticking. This ensures your crustless garden vegetable quiche will come out easily once baked. Allow the pan to sit aside as you prepare the delightful vegetable filling.
Step 2: Sauté the Zucchini
In a large skillet, heat 1 tablespoon of your chosen oil over medium heat. Add the sliced zucchini and sauté for about 5–7 minutes, cooking until it turns golden brown and tender. Once done, remove the zucchini from the skillet and set it aside, allowing its vibrant flavor to enhance the layers of your quiche.
Step 3: Cook the Aromatics
Lower the heat slightly and add the remaining oil to the skillet. Sauté the finely chopped onion for around 3–4 minutes until it’s translucent and fragrant. Stir in the minced garlic and cook for an additional minute, then add in the baby spinach. Cook just until wilted, for about 1–2 minutes, and then remove from the heat to preserve the bright green color.
Step 4: Assemble the Vegetable Layer
Spread the cooked spinach and onion mixture evenly across the bottom of your greased quiche pan, creating a colorful base for your crustless garden vegetable quiche. Next, layer the sautéed zucchini on top, followed by the thinly sliced tomatoes. Sprinkle the minced basil evenly over the vegetables to infuse the dish with an aromatic touch.
Step 5: Mix the Egg Mixture
In a large bowl, whisk together the eggs, dairy-free milk, salt, and pepper until well combined and slightly frothy. This mixture will bind all the delicious ingredients together. Pour the egg mixture over the layered vegetables in the quiche pan, making sure to cover them completely. Give the pan a gentle shake to help settle the mixture.
Step 6: Bake Until Set
Carefully place the quiche in your preheated oven and bake for 35–40 minutes, or until the center is set and the top is golden. You can check for doneness by gently shaking the pan; if it doesn’t jiggle, it’s ready! Allow your crustless garden vegetable quiche to cool slightly before slicing, as this will help maintain its structure.
Step 7: Garnish and Serve
Before serving, garnish your beautiful quiche with reserved fresh basil to add a pop of color. Slice into wedges and serve warm or at room temperature. This delightful crustless garden vegetable quiche is perfect for any meal, showcasing the robust flavors of your fresh vegetables beautifully.
