Ingredients

For the Crust

1 sheet puff pastry, pie crust, or homemade savory pastry

For the Filling

1½–2 cups butternut squash, peeled and cubed

2–4 cups fresh baby spinach

1 small onion or shallot, diced

2 cloves garlic, minced

1 tablespoon olive oil

For the Custard Base

5 large eggs

1 cup milk, half-and-half, or heavy cream

For the Cheese

¾ cup Gruyère, sharp Cheddar, Feta, Goat cheese, or a combination

¼ cup grated Parmesan cheese (optional)

Seasonings & Herbs

1–2 teaspoons fresh thyme or rosemary, chopped

½ teaspoon salt

¼ teaspoon black pepper

Pinch of nutmeg (optional)

1 teaspoon balsamic vinegar (optional)

Instructions

Prepare the Oven and Crust

Preheat the oven to 375°F (190°C).

Fit the pastry into a 9-inch pie dish or tart pan. Trim excess dough and prick the bottom lightly with a fork.

For a crisp crust, blind bake for 10 minutes, then remove and allow to cool slightly.

Roast the Butternut Squash

Place the cubed butternut squash on a baking sheet. Drizzle with olive oil and season lightly with salt and pepper.

Roast for 20–25 minutes until tender and lightly caramelized. Set aside to cool.

Cook the Vegetables

Heat a skillet over medium heat.

Add a small amount of olive oil and sauté the onion or shallot for 4–5 minutes until softened.

Add the garlic and cook for 30 seconds.

Stir in the spinach and cook until wilted. If using balsamic vinegar, add it now and cook for another minute.

Remove from heat and allow excess moisture to evaporate.

Prepare the Custard

In a large bowl, whisk together the eggs, milk or cream, thyme or rosemary, salt, pepper, and nutmeg until smooth.

Assemble the Quiche

Spread the roasted butternut squash evenly across the crust.

Add the spinach mixture over the squash.

Sprinkle the cheese evenly throughout the filling.

Pour the egg mixture over everything, ensuring it is distributed evenly.

Top with Parmesan cheese if using.

Bake the Quiche

Bake for 35–40 minutes, or until the center is set and the top is lightly golden.

A knife inserted near the center should come out mostly clean.

Cool and Serve

Allow the quiche to rest for 10–15 minutes before slicing. Serve warm or at room temperature.

Tips

Roast the Squash Thoroughly

Roasting enhances sweetness and prevents excess moisture from affecting the filling.

Blind Bake the Crust

Pre-baking helps keep the crust crisp and prevents sogginess.

Remove Excess Spinach Moisture

Too much moisture can make the custard watery, so cook off excess liquid completely.

Use Fresh Herbs

Fresh thyme or rosemary provides superior flavor compared to dried herbs.

Choose Full-Fat Dairy

Cream or half-and-half creates a richer and silkier custard texture.

Let Ingredients Cool Slightly

Adding very hot vegetables to the egg mixture can partially cook the eggs.

Don’t Overfill the Crust

Leave a little space at the top to prevent overflow during baking.

Check for Doneness Carefully

The center should have a slight jiggle but not appear liquid.

Rest Before Slicing

Allowing the quiche to cool slightly helps the custard firm up.

Serve with Fresh Greens

A crisp salad complements the rich flavors beautifully.

Variations

Goat Cheese and Rosemary Quiche

Mushroom and Squash Quiche

Skip the pastry entirely for a lower-carb option.

Gruyère and thyme create a classic French-style flavor combination.
