Ingredients You’ll Need

Gathering the right ingredients is where this Butternut Squash, Caramelized Onion, and Goat Cheese Quiche begins its magic. Each component plays a crucial role; from the flaky crust and savory cheeses to the sweet squash and aromatic herbs, these simple ingredients combine to create extraordinary depth and color.

• Pie crust: A rolled and fitted 9-inch crust forms the buttery, flaky foundation that holds everything together beautifully.
• Mozzarella or Monterey Jack cheese (¾ cup): Adds melty creaminess and helps bind the filling smoothly.
• Goat cheese (4 oz): This tangy cheese gives the quiche its signature creamy and slightly sharp flavor.
• Onions (1 cup thinly sliced): Either fresh or caramelized, onions bring sweetness and depth to every bite.
• White wine or Madeira (¼ cup): Used to deglaze the onions, it introduces a subtle acidity and enhances their caramelized notes.
• Butter or olive oil (2 tbsp): For gently cooking the onions to golden perfection.
• Thyme (½ tsp and 1 tsp): Fresh or dried thyme infuses a fragrant herbal element that complements the squash and cheese.
• Roasted butternut squash (1 cup): Soft, sweet, and tender, roasting unlocks the squash’s natural sugars and mellow flavor.
• Olive oil or vegetable oil (2 tbsp): Used for roasting the squash, this adds a lovely richness and caramelization.
• Salt and freshly ground black pepper (to taste): Essential for seasoning the layers and brightening the entire quiche.
• Large eggs (3): Provide the custard base that sets the quiche.
• Whole milk, half and half, or cream (1½ cups): Gives the custard a luscious texture and richness.
• Nutmeg (⅛ tsp): Just a pinch adds warm, aromatic depth to the custard mixture.

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

Step 1: Caramelize the Onions

Start by heating a heavy-bottomed pan over medium-high heat. Toss in your thinly sliced onions with a pinch of salt, pepper, and ½ teaspoon of thyme. The goal here is patience: lower the heat to medium-low once the onions soften, and stir occasionally. To avoid burning, deglaze the pan frequently with a splash of white wine, Madeira, or even water. This gentle cooking method transforms the onions into a deeply golden, sweetly complex base that will elevate the entire quiche.

Step 2: Roast the Butternut Squash

While the onions do their thing, preheat your oven to between 375°F and 425°F. Peel the squash, remove the seeds, and slice it into uniform half-inch cubes or slices. Toss these with olive oil, salt, and pepper before roasting on a sheet pan. Roast until the squash is tender and easily pierced with a fork, about 25 to 30 minutes. This step unlocks the natural sugars of the squash, creating a sweet, caramelized edge that contrasts beautifully with the savory onions and tangy goat cheese.

Step 3: Prepare the Quiche Custard

In a mixing bowl, whisk together the eggs until smooth, then add the milk or cream, remaining thyme, salt, pepper, and a pinch of nutmeg. This custard will bind all the flavors and set beautifully during baking, enveloping the squash, onions, and cheeses in a luscious blanket of richness.

Step 4: Assemble the Quiche

Preheat the oven to 375°F. Start by layering the bottom of your pie crust with shredded mozzarella or Monterey Jack to add a melty, protective layer. Next, scatter the roasted butternut squash evenly, followed by generous dollops of goat cheese and the caramelized onions. Pour the custard mixture over the filling slowly, letting it seep into every corner. Place the pie plate on a baking sheet to catch any drips, and bake for 30 to 40 minutes. The quiche is done when the center is just set and the edges and crust turn a beautiful golden brown.

Step 5: Let it Cool

Once out of the oven, allow the Butternut Squash, Caramelized Onion, and Goat Cheese Quiche to rest for at least 10 to 15 minutes. This resting time lets the custard finish setting so that when you slice it, each piece holds its shape perfectly without being runny.

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

Garnishes

Fresh herbs like thyme or a sprinkle of flaky sea salt on top add that final pop of color and flavor. A scattering of toasted pumpkin seeds also brings a pleasant crunch and complements the roasted squash beautifully. But nothing beats a simple drizzle of good-quality olive oil or a spoonful of tangy sour cream on a slice for added richness.

Side Dishes

This quiche pairs wonderfully with a crisp green salad dressed in a bright vinaigrette—think arugula with lemon and olive oil—to cut through the richness. Roasted root vegetables or a light tomato soup also make for cozy companions that perfectly round out the meal without overwhelming the delicate flavors of the quiche.

Creative Ways to Present

You can serve the quiche warm or at room temperature, making it wonderfully versatile. For brunch gatherings, slice it into small squares and arrange on a platter with colorful garnishes. This Butternut Squash, Caramelized Onion, and Goat Cheese Quiche also shines when paired with a glass of crisp white wine or sparkling apple cider for festive occasions.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover the quiche tightly with plastic wrap or store it in an airtight container in the refrigerator. It will stay fresh for up to 3 to 4 days, making it a fantastic option for easy weekday lunches or quick meals on the go.

Freezing

If you want to enjoy the quiche later, wrap cooled slices individually in plastic wrap and then aluminum foil before placing them in a freezer-safe container. Frozen quiche stays good for up to 2 months and reheats nicely without losing flavor or texture.

Reheating

The best way to reheat your quiche is in a preheated oven at 350°F until warmed through, about 15 to 20 minutes. This method keeps the crust crispy and the filling creamy. For a quicker option, microwave on medium power in short bursts, but the crust may lose some of its crispness.

FAQs

Can I use frozen pie crust for this quiche?

Absolutely! Frozen pie crusts work wonderfully and save time. Just thaw according to package instructions before filling and baking. A pre-baked crust can also help prevent sogginess if you prefer extra crispness.

Is it possible to make this quiche vegetarian?

Yes! This recipe is naturally vegetarian, as it uses no meat or meat-based broths. Just be sure to use vegetable stock or water if substituting the white wine when caramelizing onions to keep it fully vegetarian.

Can I substitute the butternut squash with other vegetables?

Definitely. Sweet potatoes, acorn squash, or delicata squash make great alternatives. For a different twist, try roasted zucchini or spinach, but the sweet, nutty flavor of butternut squash is hard to beat in this quiche.

How do I know when the quiche is fully cooked?

The quiche is done when the custard is set in the center but still slightly jiggles when you gently shake the pan. The edges and crust should be lightly golden brown. Overbaking can make it dry, so keep an eye on it after the 30-minute mark.

Can this quiche be served cold or only warm?

This quiche is delicious both warm and cold. Warm it for a comforting meal, or enjoy it chilled on a picnic or packed lunch. The flavors even mellow and deepen when served cold, making it quite versatile.
