How to Make Butternut Squash, Goat Cheese and Caramelized Onion Quiche Recipe

Step 1: Caramelize the Onions

Start by heating a heavy pan over medium-high heat. Add thinly sliced onions along with a pinch of salt, pepper, and thyme. Once the onions soften, reduce the heat to low to encourage slow caramelization, stirring occasionally. To prevent burning and develop depth, deglaze the pan with a splash of white wine, Madeira, or even vegetable stock whenever the onions look dry. This slow cooking process transforms the onions from sharp and pungent to sweet and melt-in-your-mouth tender, creating a foundation of rich flavor that makes this Butternut Squash, Goat Cheese and Caramelized Onion Quiche Recipe shine.

Step 2: Roast the Butternut Squash

Preheat your oven to about 400°F. Peel, seed, and slice your butternut squash into even half-inch pieces, then toss them on a sheet pan with olive oil, salt, and pepper. Roast until they are fork-tender and lightly caramelized, enhancing their natural sweetness and giving your quiche a tender, satisfying texture. This roasted squash adds not only flavor but beautiful color that makes the dish visually inviting.

Step 3: Prepare the Quiche Custard

In a mixing bowl, whisk your eggs until smooth and carefully blend in the milk or cream, fresh or dried thyme, salt, black pepper, and a pinch of freshly grated nutmeg. This custard mixture is the luscious glue that holds the quiche filling together, offering a silky consistency that contrasts beautifully with the roasted veggies and flaky crust. Taking the time to mix these ingredients well ensures every slice has a creamy, flavorful custard base.

Step 4: Assemble and Bake the Quiche

Heat your oven to 375°F and roll out the pie crust into your 9-inch pie plate. Sprinkle shredded mozzarella evenly over the bottom; this layer helps keep the crust crisp by acting as a moisture barrier. Then, distribute the roasted butternut squash, dollops of tangy goat cheese, and those golden caramelized onions evenly across the crust. Pour the custard over the filling slowly, allowing it to settle gently. Bake the quiche on a sheet pan for about 30 to 40 minutes, or until the center is just set and the crust is a gorgeous golden-brown. Let it rest for at least 10 to 15 minutes; this pause lets the custard firm up beautifully, making slicing neat and effortless.

Garnishes

A sprinkle of fresh thyme leaves or chopped chives brightens up each slice, adding a fresh, herbaceous note that pairs perfectly with the creamy filling. For a touch of elegance, a light drizzle of balsamic glaze adds a subtle tang that complements the caramelized onions beautifully.

Side Dishes

Creative Ways to Present

Consider serving the Butternut Squash, Goat Cheese and Caramelized Onion Quiche Recipe in individual mini tart shells for charming, portion-controlled bites at brunch or parties. Alternatively, top each slice with a poached egg or a smear of herb-infused crème fraîche to elevate the presentation and flavor even more.

Make Ahead and Storage

Storing Leftovers

Once cooled, wrap leftover quiche tightly in plastic wrap or place in an airtight container and refrigerate for up to 3 days. The flavors intensify overnight, making for delicious next-day meals or snacks.

Freezing

This quiche freezes well before baking. Assemble it in a freezer-safe pie plate, wrap tightly in foil, and freeze for up to 2 months. When ready, bake directly from frozen with a slight adjustment to cooking time, ensuring a fresh-from-the-oven taste whenever you need it.

Reheating

Reheat slices gently in a 350°F oven for about 15 minutes until warmed through, avoiding the microwave to preserve the flaky crust. This method revives the quiche’s texture and flavors beautifully, as if freshly baked.

FAQs

Can I make the caramelized onions ahead of time?

Absolutely! Caramelized onions can be made a day or two in advance and stored in the refrigerator. This is a great time saver and allows the flavors to deepen even further before assembling your quiche.

What can I substitute for goat cheese?

If goat cheese is not your favorite, cream cheese or ricotta make good alternatives, offering creaminess without overpowering the delicate balance of this quiche. Just keep in mind that goat cheese brings a unique tang that’s part of the magic here.

Can I use a store-bought pie crust?

Definitely! A good-quality store-bought pie crust works perfectly and saves time without compromising taste. Just be sure to follow package instructions for prebaking if needed.

Is this quiche suitable for vegetarians?

Yes, this Butternut Squash, Goat Cheese and Caramelized Onion Quiche Recipe is naturally vegetarian, packed with vegetables and dairy without any meat or fish products.

How do I know when the quiche is done baking?

The quiche is ready when the center is just set but still slightly jiggly—this ensures it stays creamy after cooling—and the crust has turned a lovely golden brown. To check, gently shake the pan; if the custard moves as one, it’s perfect.
