Sweet Potato Crust Quiche Ingredients
For the Crust
• Sweet Potatoes – Provides the foundation of a gluten-free crust that’s naturally sweet.
• Olive Oil – Essential for greasing the pie dish and enhancing the flavor of the crust.
For the Filling
• Yellow Onion – Adds a savory depth; consider using shallots for a sweeter touch.
• Garlic – Brings a robust flavor; omit for a milder quiche if preferred.
• Fresh Baby Spinach – This nutrient-packed green brightens the dish; kale or Swiss chard work as a substitute.
• Eggs – The binding and protein-rich base for your filling that makes it satisfying.
• Reduced-Fat Greek Yogurt – Contributes to the fluffiness with lower fat than cream; swap with coconut yogurt for dairy-free.
• Feta or Goat Cheese – Adds that signature tang; easily replaced with a dairy-free cheese or omitted for vegan options.
• Roma Tomatoes – Freshness and color in every bite; bell peppers can be used or left out altogether.
• Salt and Pepper – The fundamental seasonings; adjust these to suit your individual taste.
• Crushed Red Pepper (optional) – Introduces a layer of heat; leave it out for a milder dish.
This Sweet Potato Crust Quiche with Spinach & Feta is both comforting and nourishing, setting the stage for a delightful meal any time of the day!
Step‑by‑Step Instructions for Sweet Potato Crust Quiche with Spinach & Feta
Step 1: Preheat and Prepare Oven
Begin by preheating your oven to 375°F (190°C). This temperature ensures your Sweet Potato Crust Quiche bakes evenly. While the oven heats up, gather your equipment—a mandoline slicer or sharp knife will help slice the sweet potatoes, and a 9-inch pie dish will serve as your quiche base.
Step 2: Slice the Sweet Potatoes
Thinly slice the sweet potatoes into approximately 1/8-inch thick rounds. A mandoline slicer works best for uniformity, but if using a knife, aim for even slices to ensure consistent cooking. These slices will form the crust, so take your time to get them just right for the upcoming assembly.
Step 3: Arrange the Crust
Lightly grease your pie dish with olive oil spray to prevent sticking. Begin arranging the sweet potato slices in a spiral pattern, overlapping them slightly on the bottom and sides of the dish. This method will create a beautiful, sturdy crust for your Sweet Potato Crust Quiche, holding all the delicious filling.
Step 4: Bake the Crust
Once your crust is assembled, spray the top of the sweet potatoes lightly with olive oil and sprinkle with salt and pepper to taste. Place the pie dish in the preheated oven and bake for 15 minutes. You want the sweet potatoes to start softening and slightly crisping around the edges.
Step 5: Sauté the Vegetables
While the crust bakes, heat a tablespoon of olive oil in a skillet over medium heat. Add the chopped onion and sauté until softened, about 5 minutes. Next, stir in minced garlic and fresh baby spinach, cooking until the spinach is wilted and vibrant, which will take about 2-3 minutes. This mixture adds both flavor and nutrients to your quiche.
Step 6: Prepare the Egg Mixture
In a mixing bowl, whisk together the eggs and reduced-fat Greek yogurt until the mixture is fluffy and well combined. This will serve as the rich filling for your Sweet Potato Crust Quiche. Gently fold in the crumbled feta cheese, along with salt, pepper, and any herbs of your choice, blending well for even distribution.
Step 7: Assemble the Quiche
Once the crust is pre-baked, remove it from the oven and spread the sautéed spinach and onion mixture evenly over the sweet potato base. Pour the egg and yogurt mixture carefully over the top, ensuring it covers the vegetables completely. Then, arrange slices of Roma tomatoes on top for added freshness and a burst of color.
Step 8: Bake the Quiche
Return the assembled quiche to the oven and bake for 30-35 minutes, or until the egg mixture is set and the edges of the sweet potato crust are golden. The quiche should appear puffed and slightly firm in the center, a sign it’s ready to be enjoyed.
Step 9: Cool and Serve
Once baked, take the Sweet Potato Crust Quiche out of the oven and let it cool for 5-10 minutes before slicing. This resting period allows the filling to settle, making it easier to serve. Enjoy this delightful quiche warm or at room temperature, perfect for any meal of the day!

Make Ahead Options
These Healthy Sweet Potato Crust Quiche with Spinach & Feta are perfect for meal prep, allowing you to enjoy a nutritious dish even on your busiest days! You can prepare the sweet potato crust and sauté the spinach mixture up to 24 hours in advance; simply store them separately in airtight containers in the refrigerator. When you’re ready to serve, just assemble the quiche by whisking together the eggs and Greek yogurt, pouring it over the prepped ingredients, and topping it with fresh tomatoes. Bake as directed, and you’ll have a delicious, comforting meal ready with minimal effort, just as vibrant and tasty as when made fresh!
