Ingredients You’ll Need

The beauty of the Butternut Squash, Caramelized Onion, and Goat Cheese Quiche lies in its simple yet stellar ingredients. Each one plays a crucial role, from the golden roasted squash adding sweetness and softness, to the goat cheese delivering tangy creaminess, and the buttery crust providing that perfect flaky base.

• Pie crust: A rolled and fitted 9-inch pie crust forms the sturdy, flaky base that holds all the delicious fillings together.
• Shredded mozzarella or Monterey Jack cheese: Provides a melty, mild layer that balances the tangy goat cheese and adds gooey texture.
• Goat cheese: Adds creamy tartness and a luscious contrast to the sweetness of the squash.
• Thinly sliced onions: When caramelized, these add incredible depth and sweetness to the quiche.
• White wine, Madeira, sherry, or vermouth: Used to deglaze the onions, bringing complexity and a subtle acidity.
• Butter or olive oil: Essential for gently cooking the onions and roasting the squash, adding richness.
• Thyme: Fresh or dried thyme provides an earthy herbal note that ties the flavors together beautifully.
• Roasted butternut squash: Soft, tender cubes offer natural sweetness and a smooth texture contrast.
• Salt and freshly ground black pepper: Basic but vital seasonings to enhance every other ingredient’s flavor.
• Eggs: The backbone of the custard, eggs bind everything together into that silky quiche filling.
• Whole milk, half and half, or cream: Adds creaminess and richness to the custard for a luscious, tender bite.
• Nutmeg: Just a pinch brightens the custard with warm spice and depth.

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

Step 1: Caramelize the Onions

Start by heating a heavy pan over medium-high heat and adding your thinly sliced onions along with a pinch of salt, pepper, and thyme. Lower the heat once they begin to soften to prevent burning, stirring frequently. Slowly cook the onions until they turn a rich, deep golden brown. Deglaze the pan occasionally with a splash of white wine or vegetable stock to keep the onions moist and develop their sweet, complex flavor. This step takes patience but is absolutely worth it—these caramelized onions are pure magic in this quiche.

Step 2: Roast the Butternut Squash

Preheat your oven to between 375 and 425 degrees Fahrenheit. Peel the butternut squash, remove its seeds, and cut it into uniform half-inch slices or cubes. Toss the squash with olive oil, salt, and pepper, then spread it evenly on a sheet pan. Roast until the pieces are tender and lightly caramelized, which adds a delightful natural sweetness and soft texture that will hold up beautifully inside the quiche.

Step 3: Prepare the Quiche Custard

In a large bowl, whisk together the eggs until smooth. Add your choice of milk, cream, or half and half, along with thyme, salt, pepper, and just a hint of freshly grated nutmeg. Whisk until everything is fully combined and the custard is silky. This mixture will set the filling and harmonize the rustic veggies and tangy cheese into a creamy delight.

Step 4: Assemble and Bake Your Butternut Squash, Caramelized Onion, and Goat Cheese Quiche

Raise your oven temperature to 375 degrees Fahrenheit. Line the pre-fitted pie crust with a generous layer of shredded mozzarella—this helps prevent a soggy bottom and adds melty goodness. Spread the roasted butternut squash evenly over the cheese. Scatter dollops of goat cheese and spoon your sweet caramelized onions on top, spreading them out for even flavor in every slice. Pour the custard mixture carefully over all the fillings. Place your quiche on a baking sheet to catch any drips, then bake for 30 to 40 minutes. When the center is just set and the crust looks golden and inviting, it’s ready. Let the quiche rest for at least 10 to 15 minutes before slicing so the custard can firm up perfectly.

Garnishes

A sprinkle of fresh thyme leaves or a scattering of finely chopped chives over your slices adds a fresh, vibrant note. A drizzle of good quality olive oil or a few toasted pine nuts can also lend an extra layer of texture and flavor without overpowering the quiche.

Side Dishes

Pair this quiche with a crisp green salad tossed in a light vinaigrette to balance the richness of the custard. Roasted root vegetables or a warm bowl of homemade soup also make comforting companions for a lovely, well-rounded meal.

Make Ahead and Storage

Storing Leftovers

Once cooled completely, cover leftovers tightly with plastic wrap or store in an airtight container in the refrigerator. The quiche will stay fresh and flavorful for up to four days, making it perfect for quick meals throughout the week.

Freezing

You can freeze baked quiche in individual slices or whole. Wrap well in plastic wrap and foil to prevent freezer burn. Frozen quiche is best enjoyed within two months and makes for a convenient and delicious ready-to-eat option.

Reheating

Reheat leftover quiche in a 350-degree oven until warmed through to preserve the flaky crust and creamy filling. Avoid the microwave if you want to keep that perfect texture, but it works well in a pinch.

FAQs

Can I use a store-bought pie crust for this quiche?

Absolutely! A good quality store-bought crust works wonderfully and saves time. Just make sure to fit it well into your pie plate and prick the bottom lightly to prevent sogginess.

Can I substitute the butternut squash with another vegetable?

Yes, sweet potatoes or acorn squash can be great alternatives and will give a similarly sweet and tender texture to your quiche.

What cheese works best besides goat cheese?

While goat cheese provides that signature tang, cream cheese or ricotta can be mild alternatives, though they will change the flavor profile slightly.

Can I make this quiche vegetarian?

This recipe is already vegetarian-friendly, but if you want to add protein, consider tossing in cooked spinach, mushrooms, or a bit of crispy tempeh for extra texture and taste.

How do I know when the quiche is fully baked?

The quiche is ready when the center is just set and not jiggly. The edges should be golden brown. Let it cool slightly before slicing to allow the custard to firm up perfectly.
