Introduction

This Butternut Squash, Goat Cheese, and Caramelized Onion Quiche is a comforting and flavorful dish perfect for brunch or a light dinner. With the sweetness of roasted squash and onions balanced by creamy goat cheese, it’s a delicious way to enjoy seasonal produce.

Ingredients

• 1 pie crust, rolled and fitted to 9″ pie plate
• ¾ cup shredded mozzarella or Monterey Jack cheese
• 4 oz goat cheese
• 1 cup thinly sliced onions (¼” slices) (1-2 medium-small onions) or ½ cup caramelized onions
• ¼ cup white wine, Madeira, sherry, vermouth, or substitute vegetable stock or water
• 2 tbsp butter or olive oil
• ½ tsp thyme
• 1 cup roasted butternut squash, peeled and sliced or diced
• 2 tbsp olive oil or other vegetable oil
• Salt and freshly ground black pepper, to taste
• 3 large eggs
• 1 ½ cups whole milk, half and half, heavy cream, or a blend
• 1 tsp thyme (fresh or dried)
• 1 tsp salt
• ½ tsp black pepper (to taste)
• ⅛ tsp nutmeg (preferably freshly grated)

Instructions

1. Step 1: Caramelize the onions by heating a heavy pan on medium-high heat. Add the sliced onions, salt, pepper, and ½ tsp thyme. Once softened, reduce heat to low and stir occasionally.
2. Step 2: Add a splash of white wine, Madeira, sherry, stock, or water as needed to deglaze the pan and prevent sticking. Continue cooking until the onions are deeply colored and sweet, then set aside.
3. Step 3: Preheat the oven to 375-425 ℉. Peel and seed the butternut squash, then slice or dice into uniform half-inch pieces.
4. Step 4: Toss the squash with olive oil, salt, and pepper. Spread on a sheet pan and roast until tender and easily pierced by a fork. Remove from oven and set aside.
5. Step 5: In a medium-large bowl, whisk together eggs, milk or cream, 1 tsp thyme, salt, pepper, and nutmeg until well combined.
6. Step 6: Preheat the oven to 375℉ if you lowered it. Line the bottom of the pie crust with shredded mozzarella.
7. Step 7: Evenly spread the roasted butternut squash, dollops of goat cheese, and caramelized onions over the cheese layer.
8. Step 8: Pour the egg custard mixture gently over the filling. Place the quiche on a sheet pan to catch any spills, then bake for 30-40 minutes.
9. Step 9: The quiche is done when the center is just set and the crust is lightly golden. Let cool 10-15 minutes before slicing to allow it to firm up.

Tips & Variations

• For extra flavor, sprinkle fresh herbs like sage or rosemary into the custard mixture.
• Use caramelized onions from the store as a shortcut, or substitute with sautéed shallots for a milder taste.
• Try a gluten-free pie crust or a homemade whole wheat crust for a different texture.
• Add a pinch of red pepper flakes to the onions for a subtle heat.
• Leftover quiche can be enjoyed cold or reheated gently in the oven to keep the crust crisp.

Storage

Store leftover quiche in an airtight container in the refrigerator for up to 3-4 days. To reheat, warm slices in a 350℉ oven for about 10-15 minutes until heated through, which helps maintain the crust’s crispness better than a microwave.

FAQs

Can I make this quiche ahead of time?

Yes, you can prepare the filling and crust ahead, then assemble and bake just before serving. Alternatively, fully bake the quiche and reheat it gently when ready to eat.

Mozzarella or Monterey Jack provide a mild, melty base, while goat cheese adds a tangy creaminess. You can experiment with other mild cheeses like Gruyère or fontina if desired.

Ingredients

Scale 1x2x3x

Pie Crust

• 1 each pie crust, rolled and fitted to 9″ pie plate (see post for tips and recipe link or use your favorite pastry crust)

Cheeses and Vegetables

• ¾ cup mozzarella or Monterrey Jack cheese, shredded
• 4 oz goat cheese
• 1 cup thinly sliced onions (¼” slices) (1–2 medium-small onions) (or substitute ½ cup caramelized onions)
• 1 cup butternut squash, roasted (peeled, sliced or diced)

Caramelized Onion Ingredients

• ¼ cup white wine, Madeira, sherry, or vermouth (can substitute vegetable stock or water)
• 2 tbsp butter or olive oil
• ½ tsp thyme
• Salt and freshly ground black pepper, to taste

Roasted Butternut Squash

• 2 tbsp olive oil or other vegetable oil
• Salt and freshly ground black pepper, to taste

Quiche Custard

• 3 large eggs
• 1 ½ cups whole milk, half and half, heavy cream, or a blend
• 1 tsp thyme (fresh leaves or dried)
• 1 tsp salt
• ½ tsp black pepper (to taste)
• ⅛ tsp nutmeg (preferably a pinch of freshly grated nutmeg)

Instructions

1. Caramelize the Onions: Heat a heavy pan over medium-high heat and add the sliced onions along with salt, pepper, and thyme. Once the onions begin to soften, reduce the heat to low. Add a splash of white wine, Madeira, sherry, stock, or water as needed to keep the onions from drying out and burning, scraping the pan to deglaze. Continue cooking, stirring occasionally, until the onions are deeply colored and sweet.
2. Roast the Butternut Squash: Preheat the oven to 375-425 ℉. Peel the butternut squash, cut it in half, remove seeds, then slice or dice into uniform half-inch pieces. Place on a sheet pan, drizzle with olive oil, and season with salt and pepper. Roast until the squash is tender and easily pierced with a fork.
3. Prepare the Custard: In a medium-large bowl, whisk the eggs until uniform. Add the milk or cream, thyme, salt, pepper, and nutmeg, whisking well to combine all ingredients into a smooth custard mixture.
4. Assemble the Quiche: Preheat the oven to 375 ℉. Line the bottom of the pie crust with shredded mozzarella or Monterrey Jack cheese. Spread the roasted butternut squash evenly over the cheese. Distribute dollops of goat cheese and the caramelized onions across the squash layer.
5. Bake the Quiche: Carefully pour the egg custard over the filling in the pie crust. Place the quiche on a sheet pan to catch any spills and bake in the oven for 30-40 minutes. The quiche is done when the center is just set, and the top and crust are lightly golden brown.
6. Cool and Serve: Let the quiche cool for at least 10-15 minutes before slicing. This resting time allows the custard to firm up for clean slices. Serve warm or at room temperature.

Notes

• You can substitute caramelized onions for freshly sliced onions for a richer flavor.
• Use your preferred type of shredded cheese for a different melting texture and taste.
• The quiche can be made with half and half or heavy cream for a richer custard or with whole milk for a lighter version.
• Make sure to roast the butternut squash evenly for consistent tenderness.
• Baking the quiche on a sheet pan helps avoid oven spills.
• Allow at least 10-15 minutes cooling time to ensure the quiche sets properly before slicing.
