FULL RECIPE

Ingredients

1.For the crust:

• 2 medium sweet potatoes, peeled and thinly sliced into rounds
• 1 tablespoon olive oil
• Salt and pepper, to taste

2.For the filling:

• 6 large eggs
• 1/2 cup full-fat coconut milk (or unsweetened almond milk)
• 1 cup fresh spinach, chopped
• 1/2 red bell pepper, diced
• 1/2 small red onion, finely chopped
• 1/2 cup cooked bacon or sausage, crumbled (optional)
• 1/4 teaspoon garlic powder
• Salt and pepper, to taste

Directions

1. Preheat oven: Preheat your oven to 375°F (190°C).
2. Prepare the crust: Lightly grease a 9-inch pie dish with olive oil. Arrange sweet potato slices in overlapping layers on the bottom and sides of the dish to form a crust. Brush with olive oil and season with salt and pepper.
3. Pre-bake the crust: Bake the crust for 20 minutes, until the edges begin to crisp slightly. Remove from the oven and set aside.
4. Make the filling: In a mixing bowl, whisk together eggs, coconut milk, garlic powder, salt, and pepper. Stir in spinach, bell pepper, onion, and bacon or sausage (if using).
5. Assemble the quiche: Pour the egg mixture into the pre-baked sweet potato crust. Spread evenly with a spatula.
6. Bake: Return to the oven and bake for 30–35 minutes, or until the center is set and the top is lightly golden.
7. Cool and serve: Let the quiche cool for 5–10 minutes before slicing. Serve warm or at room temperature.

Health Benefits of a Sweet Potato Crust

Using sweet potatoes as a crust alternative offers numerous health benefits, making this quiche a smarter choice than traditional pastry-based options. Sweet potatoes are rich in fiber, antioxidants, and beta-carotene, a powerful nutrient that supports immune function and vision health. They also have a lower glycemic index compared to regular white potatoes, helping to regulate blood sugar levels. Because sweet potatoes are naturally gluten-free, they’re an ideal base for those avoiding wheat. This nutrient-dense crust option boosts the overall nutritional profile of the quiche without compromising on taste or texture.

Paleo-Friendly and Gluten-Free

This recipe is tailored for those following paleo and gluten-free diets, thanks to its clean ingredient list. Unlike conventional quiches that rely on flour or pastry dough, this one swaps in wholesome sweet potatoes, which are paleo-approved and naturally grain-free. The filling uses eggs, vegetables, and coconut milk—ingredients that align with paleo principles while remaining free of processed grains and dairy. For those managing food sensitivities, this quiche offers a safe, satisfying meal that doesn’t rely on gluten or refined ingredients.

Customizable Fillings for Every Preference

One of the most appealing aspects of this quiche is how customizable it is. The basic recipe includes spinach, red bell peppers, and onions, but you can easily swap or add vegetables based on what’s in season or in your fridge. Mushrooms, zucchini, kale, or sun-dried tomatoes work wonderfully. For protein, you can add crumbled bacon, turkey sausage, or even shredded rotisserie chicken. Vegetarians can skip the meat entirely or add plant-based sausage alternatives. This flexibility makes the quiche suitable for a wide range of preferences and dietary needs.

Perfect for Meal Prep and Make-Ahead Meals

This sweet potato crust quiche is a great addition to any meal prep routine. It stores well in the refrigerator for several days and can be sliced into individual portions for easy grab-and-go breakfasts or lunches. Reheating is simple—just pop a slice in the microwave or oven until warmed through. Since the flavors continue to develop after cooking, the quiche often tastes even better the next day. You can also make it the night before a brunch or gathering, then reheat and serve the next morning without stress.

Flavor and Texture Highlights

The texture and flavor of this quiche are both comforting and gourmet. The sweet potato crust becomes slightly crispy on the edges while staying tender at the base, offering a delightful contrast to the fluffy, custard-like filling. The sweetness of the crust complements the savory flavors of the eggs, vegetables, and any proteins added, creating a harmonious balance. Coconut milk adds a subtle creaminess without overpowering the dish, and seasonings like garlic powder and pepper enhance the overall taste without needing complex spices.

Low-Carb and High-Protein Option

This recipe strikes an excellent balance for those watching their carbohydrate intake but still seeking a satisfying and protein-rich meal. While sweet potatoes do contain carbs, they’re complex carbohydrates that digest slowly and support sustained energy levels. The eggs and optional added meat deliver a high-protein profile, ideal for keeping you full and supporting muscle health. Compared to traditional quiche with a pastry crust, this version is lower in refined carbohydrates and offers better overall macronutrient distribution, making it suitable for low-carb and high-protein diets.

Kid-Friendly and Family-Approved

Despite its nutritious ingredients, this quiche is kid-approved and family-friendly. The naturally sweet crust appeals to younger palates, and the colorful vegetables make it visually inviting. If your children are picky eaters, the vegetables can be finely chopped or lightly sautéed before baking to mellow their flavor. You can also customize the filling with their favorite add-ins like cheese (if not strictly paleo), ham, or bell peppers. It’s a fun and healthy way to introduce more vegetables into your family’s diet without the usual fuss.

Serving Suggestions and Presentation Tips

For the best presentation, allow the quiche to cool slightly before slicing to help it set. This ensures clean, even slices that show off the layers of sweet potato and colorful filling. Garnish with a sprinkle of fresh herbs such as parsley or chives for an extra pop of color and flavor. This quiche pairs wonderfully with a side of mixed greens dressed in lemon vinaigrette or fresh fruit for a complete brunch or light lunch. Serving it on a rustic wooden board or white platter adds a beautiful, homey touch to any table.

Storage and Freezing Tips

Proper storage will help maintain the freshness and flavor of your quiche. After it cools, store leftovers in an airtight container in the refrigerator for up to four days. To freeze, wrap individual slices in parchment paper and place them in a freezer-safe bag or container. When ready to eat, thaw overnight in the fridge and reheat in a 350°F (175°C) oven for 10–15 minutes or until hot. This makes it a convenient option for busy mornings when you want a homemade meal without the prep time.

Ideal for Brunches and Gatherings

Whether you’re hosting a holiday brunch, baby shower, or casual weekend get-together, this quiche is sure to be a hit. It’s elegant enough to serve guests yet simple and hearty enough to satisfy all kinds of appetites. Because it’s naturally dairy-free and gluten-free, it caters to a wide range of dietary restrictions, making it an inclusive dish for gatherings. It also travels well and can be made ahead of time, meaning less time in the kitchen and more time enjoying your guests’ company.
