Ingredients You’ll Need

This Sweet Potato Quiche stars simple ingredients, but each one brings something essential—creamy texture, sweet depth, and a pop of tang from the goat cheese. The colors are just as inviting as the flavors, making every slice a feast for the senses.

• Whole Wheat Pie Crust (or your favorite pie crust): Adds a nutty depth and hearty base for the quiche; store-bought or homemade both work beautifully.
• Extra Virgin Olive Oil: Used for roasting and sautéing, it coaxes out the natural sweetness of the vegetables.
• Large Sweet Potatoes: The star of the show—once roasted, they become wonderfully tender and sweet, lending color and flavor to every bite.
• Kosher Salt: Enhances and balances the savory-sweet flavors throughout the recipe.
• Large Yellow Onion: Sautéed until deeply golden and soft, for a touch of caramelized magic.
• Large Eggs: The quiche’s binding hero—creating a custardy, creamy texture as it bakes.
• Milk: Brings softness to the custard and helps keep everything light and balanced.
• Ground Nutmeg: Just a pinch gives warmth and complexity that compliments both sweet potatoes and goat cheese.
• Goat Cheese: Adds creamy tang and pockets of flavor, melting beautifully into the filling.
• Fresh Rosemary: This savory herb infuses every bite with aromatic freshness and a hint of earthiness.

Variations

One of the best parts of making quiche is just how easy it is to riff on the original recipe. Sweet Potato Quiche is incredibly flexible—so don’t be shy about swapping in ingredients to suit your mood, your pantry, or any dietary needs.

• Cheese Swap: Try feta, sharp cheddar, or even Gruyère instead of goat cheese for a different flavor profile.
• Vegetable Medley: Add sautéed spinach, roasted red peppers, or mushrooms to the mix for more veggies and color.
• Dairy-Free: Use your favorite non-dairy milk and a vegan cheese to make this quiche suitable for dairy-free guests.
• Crustless Option: For a lighter version, skip the crust and bake the filling in a greased pie dish—just check for doneness a little earlier.

How to Make Sweet Potato Quiche

Step 1: Prepare Your Pie Crust

Start by prepping your favorite pie crust (homemade or store-bought). Fit it gently into a deep, 9-inch pie dish and pop it into the fridge—this ensures it holds its shape beautifully while you prep the filling.

Step 2: Roast the Sweet Potatoes

Wash, peel, and dice your sweet potatoes into charming little cubes. Toss them with olive oil and salt, then roast at 400°F until they’re soft and lightly caramelized—about 20 minutes. Their color and flavor easily steal the show!

Step 3: Caramelize the Onions

Thinly slice a large yellow onion and let it cook low and slow in a skillet with a splash of olive oil. Stir occasionally until the onion turns irresistibly golden and sweet, softening right down to its core.

Step 4: Par-Bake the Crust

Roll out your chilled dough, place it in your pie dish, and gently prick the bottom with a fork. Bake at 350°F for 10–15 minutes until just golden. This forms a sturdy base that stays crisp beneath the creamy filling.

Step 5: Assemble the Filling

Layer the roasted sweet potatoes on the par-baked crust, then pile on the caramelized onions, crumbled goat cheese, and fresh rosemary. At this stage, you can even cover and refrigerate the whole thing for up to 24 hours if you want to get ahead.

Step 6: Mix and Pour the Custard

In a large bowl, whisk together eggs, milk, nutmeg, and a sprinkle of salt. Pour this luscious mixture evenly over the filling, letting it weave its way between all those colorful layers.

Step 7: Bake and Enjoy

Bake your Sweet Potato Quiche at 375°F for about 45–55 minutes. You’ll know it’s done when it’s puffed and only barely jiggles in the center. Let it rest for 10 minutes before slicing—this helps everything set up perfectly. Serve warm or at room temperature and swoon!

How to Serve Sweet Potato Quiche

Garnishes

Top your quiche with a sprinkle of fresh rosemary, extra goat cheese crumbles, or a light dusting of black pepper. If you love a little zing, a quick garnish of microgreens or thinly sliced chives adds freshness and color that pop against the golden filling.

Side Dishes

This Sweet Potato Quiche is hearty on its own, but it pairs beautifully with a crisp green salad, a platter of fresh fruit, or a simple tomato basil soup. For brunchy vibes, add a basket of warm, crusty bread or fluffy scones for a table everyone will linger around.

Creative Ways to Present

Try serving your quiche as mini squares or wedges on a brunch buffet, or cut into smaller slices for elegant hors d’oeuvres at a holiday party. Stack the slices on a vibrant serving platter and scatter extra herbs or edible flowers for a picture-perfect presentation.

Make Ahead and Storage

Storing Leftovers

To keep your leftover Sweet Potato Quiche tasting fresh, wrap slices tightly or store in an airtight container in the refrigerator. It keeps well for up to 4 days, making quick and satisfying meals or on-the-go lunches an absolute breeze.

Freezing

This quiche is perfect for freezing. Let it cool completely, wrap tightly in plastic wrap and foil, and freeze for up to 2 months. To enjoy later, simply thaw in the fridge overnight—the flavor and texture hold up wonderfully.

Reheating

For best results, reheat individual slices in a 325°F oven until warmed through and the crust is crisp again—about 10–15 minutes. If you’re in a hurry, the microwave works too, though the crust will be softer.
