Step‑by‑Step Instructions for Winter Vegetable Quiche
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature ensures an evenly baked, flaky crust for your Winter Vegetable Quiche. As the oven warms up, prepare your pie crust by either placing a pre-made crust in a pie dish or rolling out homemade dough.
Step 2: Sauté the Vegetables
In a large skillet, heat a tablespoon of olive oil over medium heat. Once hot, add diced onion, sliced mushrooms, and cubes of butternut squash to the pan. Sauté these vegetables for about 5-7 minutes, stirring regularly, until they become tender and fragrant—this is when the magic happens, and your kitchen will fill with cozy aromas.
Step 3: Add Greens for Vibrancy
Now, it’s time to incorporate chopped kale into the skillet. Continue cooking for an additional 2-3 minutes, until the kale wilts down and turns a vibrant green. This step not only adds nutrition but also enhances the color of your Winter Vegetable Quiche filling, making it visually appealing.
Step 4: Prepare the Egg Mixture
In a separate bowl, whisk together four eggs with one cup of milk, adding a pinch of salt and freshly ground pepper. Whisk until the mixture is frothy and slightly airy, which helps create a light and fluffy filling for your quiche. This step is crucial for the perfect texture in your Winter Vegetable Quiche.
Step 5: Assemble the Quiche
Spread the sautéed vegetable mixture evenly across the base of your pre-baked pie crust, ensuring all ingredients are well-distributed. Pour the egg mixture over the veggies, allowing it to seep into the spaces, and top everything with a cup of shredded cheese of your choice. This creates a deliciously creamy layer on top.
Step 6: Bake to Perfection
Place the assembled quiche in the preheated oven and bake for 35-40 minutes. Keep an eye on it, checking for a golden brown top and a filling that is set—there should be no jiggle in the center. The delightful aroma will signal that your Winter Vegetable Quiche is nearly ready to serve.
Step 7: Cool and Serve
Once out of the oven, let the quiche cool for 5-10 minutes. This resting period is essential for easier slicing and serving. As the filling firms up slightly, prepare to cut into this cozy Winter Vegetable Quiche, ready to enjoy each warm, flavorful slice with family or friends.
