Step‑by‑Step Instructions for Sweet Potato Crust Quiche with Spinach & Feta

Step 1: Preheat Oven
Preheat your oven to 375°F (190°C). This temperature is crucial for creating a perfectly baked Sweet Potato Crust Quiche with Spinach & Feta. While the oven warms, you can prepare your sweet potatoes and other ingredients to save time.

Step 2: Slice Sweet Potatoes
Using a mandoline slicer or a sharp knife, slice the sweet potatoes into thin rounds, about 1/8-inch thick. Aim for even slices to ensure a uniform cooking and crispy texture. This step creates the beautiful, nutty crust that will hold all the delicious filling.

Step 3: Prepare the Pie Plate
Grease a 9-inch pie plate with olive oil cooking spray to prevent sticking. Begin layering the sweet potato slices into the plate, spiraling them outward and slightly overlapping until the bottom and sides are covered. This forms the unique crust of your Sweet Potato Crust Quiche.

Step 4: Bake the Crust
Lightly spray the arranged sweet potato crust with cooking spray and season with a pinch of salt and freshly cracked black pepper. Place the pie plate in the preheated oven and bake for 15 minutes, until the sweet potatoes are tender yet slightly firm, providing the ideal base for your quiche.

Step 5: Sauté Vegetables
In a skillet, heat a drizzle of extra-virgin olive oil over medium heat. Add the diced yellow onion and sauté for about 5 minutes, or until softened and translucent. Then, add minced garlic and fresh baby spinach, cooking for an additional 2 minutes until the spinach wilts. This mixture will add a flavorful depth to your quiche.

Step 6: Mix Egg Filling
In a mixing bowl, whisk together the eggs and reduced-fat plain Greek yogurt until the mixture is light and fluffy. Gently fold in crumbled feta, along with salt, black pepper, and crushed red pepper if desired. This creamy filling offers a delightful contrast to the sweet potato crust.

Step 7: Assemble the Quiche
Once the crust is ready, layer the sautéed spinach and onion mixture evenly in the crust. Carefully pour the egg mixture over the vegetables, ensuring an even distribution. For an extra touch, top with sliced Roma tomatoes and additional feta, enhancing both flavor and appearance.

Step 8: Bake Until Set
Return the pie plate to the oven and bake for 30-35 minutes. The quiche is ready when the egg is set and no longer jiggles in the center. Allow it to cool slightly before cutting into wedges, as this will help maintain its shape and give you beautiful slices.
