Ingredients You’ll Need

Sweet Potatoes: Use about 1 ½ lb of peeled and diced sweet potatoes. Their natural sweetness adds depth, and you can substitute with butternut squash for a different flavor.
Fresh Spinach: 4 oz of fresh spinach adds a delicious nutrient boost and vibrant green color. You can also use kale or Swiss chard if you prefer.
Olive Oil: A tablespoon of olive oil is perfect for sautéing, but feel free to use avocado oil for a mild flavor.
Pie Crust or Puff Pastry: Use a store-bought crust for ease or make your own. Puff pastry adds a delightful flakiness.
Full-Fat Milk: ¾ cup of full-fat milk creates a rich filling, but you can substitute with almond or coconut milk for a dairy-free option.
Large Eggs: You’ll need 3 eggs to help set the filling. You can try flax eggs as a substitute for a vegan quiche.
Gruyere Cheese: Add ¾ cup of grated gruyere for a nutty flavor. If unavailable, cheddar or mozzarella works well.
Parmesan Cheese: Optional but adds an extra layer of flavor—use ¼ cup, or skip it for a lighter option.
Garlic: 1 clove, finely grated, gives a lovely aromatic quality; garlic powder is an acceptable substitution.
Herbs & Spices: Season the quiche with ¼ tsp salt, ⅛ tsp black pepper, ½ tsp smoked paprika, and ¼ tsp dried thyme, rosemary, and sage for depth.

How to Make Sweet Potato Quiche

Cook the Veggies: Start by heating 1 tablespoon of olive oil in a skillet over medium heat. Add the diced sweet potatoes, sprinkle with a bit of salt, and add a few tablespoons of water to steam. Cover with a lid and cook for about 15 minutes until tender. Once done, transfer the potatoes to a bowl and sauté the fresh spinach in the same skillet until just wilted; this only takes a couple of minutes.

Preheat and Prepare: While your veggies are cooking, preheat your oven to 375° F (190° C). Next, take your prepared pie crust or puff pastry and fit it into a greased 10-inch pie pan, trimming any excess. Make sure the crust is snug in the pan—press any edges back into place if necessary to ensure a perfect fit.

Make the Filling: In a medium-sized bowl, whisk together ¾ cup of full-fat milk, 3 large eggs, smoked paprika, grated garlic, salt, and pepper until fully combined. This mixture is what will bind everything together and give the quiche its rich, luscious texture.

Assemble the Quiche: Layer the sautéed sweet potatoes and wilted spinach on the bottom of the pie crust. Then, mix in the grated gruyere and pour the egg mixture over it, ensuring to fill until about ½ inch from the rim. For an extra golden touch, brush the pastry with a beaten egg and sprinkle sesame seeds on top if desired.

Bake Until Golden: Place your quiche in the oven and bake for 30-35 minutes. You want the pastry to turn golden brown, and the egg filling should be set but still soft. Keep an eye on it after the 30-minute mark, and pull it out when it looks beautifully baked. Let it sit for about 10-15 minutes before serving—it’s best enjoyed warm or at room temperature!

Storing & Reheating

Sweet potato quiche can be stored at room temperature for a couple of hours, but for longer storage, keep it in the refrigerator for up to 3 days in an airtight container. If you’re thinking about freezing, wrap it tightly and store in freezer-safe packaging for up to 3 months. When reheating, simply pop it in the oven at 350° F (175° C) for about 15-20 minutes or until warmed through. Note that while the flavor remains delicious, the texture may change slightly; refreshing it with a sprinkle of cheese before reheating can help!

Chef’s Helpful Tips

Avoid overcooking the sweet potatoes; they should be tender yet firm enough to hold their shape in the quiche.
Make sure all your ingredients, especially the eggs and milk, are at room temperature for the best blending.
Timing is key; let the quiche cool before cutting to ensure clean slices.
Adding a pinch of nutmeg to the egg mixture enhances the flavor without being overpowering.
You can prepare the sweet potatoes and spinach a day in advance, making assembly a breeze!

Whipping up this Sweet Potato Quiche is certain to become a cherished ritual in your home. Its warmth and flavor make it a must-try, especially as you gather with loved ones. Feel free to experiment with different herbs or vegetables; after all, cooking is meant to be fun and adaptable!

To make a vegan version of this quiche, substitute eggs with 1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water for each egg. Use plant-based milk and a vegan cheese alternative, and you’ve got a tasty quiche for everyone!

What can I serve with this Sweet Potato Quiche?

This quiche pairs wonderfully with a side salad, roasted vegetables, or even a refreshing fruit salad. It’s particularly delightful with a lightly dressed arugula salad that balances the quiche’s richness.
