Ingredients You’ll Need

Every ingredient in this Butternut Squash & Sage Quiche plays a vital role, creating a balance of flavors and textures that make the dish so special. Simple but essential, these components bring charm and wholesomeness to the table.

1 unbaked 9-inch pie crust: A buttery, flaky base that holds the filling perfectly, store-bought or homemade works wonderfully.
2 cups butternut squash, peeled and diced: Roasted till tender and caramelized, it adds a sweet, nutty flavor.
1 tablespoon olive oil: To coat the squash for roasting, bringing out its natural sweetness.
Salt and pepper to taste: Essential for seasoning every layer to perfection.
1 tablespoon butter: Adds richness when sautéing onions and sage.
1 small onion, finely chopped: Provides a subtle sweetness and depth to the filling.
1 tablespoon fresh sage, chopped (or 1 teaspoon dried): Offers an aromatic, earthy note that pairs beautifully with squash.
4 large eggs: These bind the custard filling, giving the quiche its signature texture.
1 cup whole milk: Adds creaminess and moisture to the custard.
½ cup heavy cream: Elevates the richness and silkiness of the filling.
1 cup shredded Gruyère or Swiss cheese: Melts into gooey pockets with a savory, slightly nutty flavor that complements the squash.
¼ teaspoon ground nutmeg (optional): A dash of warmth that subtly enhances the custard’s flavor profile.

How to Make Butternut Squash & Sage Quiche

Step 1: Roast the Butternut Squash

Start by tossing the diced butternut squash with olive oil, salt, and pepper. Spread it evenly on a baking sheet and roast in a preheated 400°F (200°C) oven for about 20 to 25 minutes. Roasting caramelizes the squash, making it delectably tender with a naturally sweet edge. Let the squash cool slightly to avoid adding moisture to the custard later.

Step 2: Sauté Onion and Sage

While the squash roasts, melt the butter in a skillet over medium heat. Add the finely chopped onion and gently cook until soft and translucent, about 5 to 7 minutes. Then stir in the fresh sage and cook for an additional minute—this step releases the sage’s fragrant oils, imbuing the onions with herby richness.

Step 3: Prepare the Custard Mixture

In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, ground nutmeg (if using), and a pinch of salt and pepper. The custard mixture is the backbone of your quiche, so make sure the eggs are thoroughly combined to achieve a smooth, silky filling.

Step 4: Assemble the Butternut Squash & Sage Quiche

Lay your unbaked pie crust into a 9-inch pie dish and scatter half of the shredded cheese across the bottom. This cheesy layer acts as a protective barrier, preventing sogginess. Next, layer on the roasted squash and sautéed onion and sage mixture evenly over the cheese. Pour the custard gently over the filling and then sprinkle the remaining cheese on top to create a golden, bubbly crust after baking.

Step 5: Bake to Perfection

Bake the quiche in a 375°F (190°C) oven for 35 to 40 minutes. You’ll know it’s done when the center is set and a beautiful golden-brown glow appears on the top. Let the quiche cool for at least 10 minutes—this resting time helps the filling set fully and makes slicing easier, ensuring every piece holds its shape beautifully.

How to Serve Butternut Squash & Sage Quiche

Garnishes

Add a pop of color and freshness with a light sprinkle of chopped fresh sage or a few sage leaves on top right before serving. A drizzle of good-quality olive oil or a small dollop of crème fraîche can also wonderfully enhance the flavors without overpowering the delicate balance of the quiche.

Side Dishes

This Butternut Squash & Sage Quiche pairs perfectly with a crisp green salad dressed simply with lemon vinaigrette or tangy apple cider dressing. Roasted vegetables or a side of fresh fruit salad can create a colorful and inviting plate that’s ideal for any meal occasion.

Creative Ways to Present

For gatherings, serve the quiche as mini tartlets by using a muffin tin to bake individual portions. Another fun idea is to garnish each slice with a sprinkle of toasted pine nuts or a few caramelized onions to boost texture and flavor, turning this homey dish into a chic centerpiece.

Make Ahead and Storage

Storing Leftovers

Leftover Butternut Squash & Sage Quiche keeps beautifully in the refrigerator for up to 3 days when covered tightly with plastic wrap or stored in an airtight container. The flavors often meld and deepen overnight, making the second day just as delightful as the first.

Freezing

You can freeze the quiche either before or after baking. Wrap it securely in plastic wrap and aluminum foil to prevent freezer burn. Frozen quiche will maintain its quality for up to 2 months. Thaw overnight in the refrigerator before reheating for best results.

Reheating

To reheat, place the quiche in a preheated oven at 350°F (175°C) for 15 to 20 minutes until warmed through and the crust is crisp again. Avoid microwaving if possible, as it may make the crust soggy and the custard rubbery.

FAQs

Can I use frozen butternut squash for this quiche?

Absolutely! Just be sure to thaw and drain any excess moisture from the frozen squash to prevent the quiche from becoming soggy. Roasting until nicely browned will help develop that wonderful sweet flavor.

Is it possible to make this quiche vegetarian?

This Butternut Squash & Sage Quiche is already vegetarian-friendly, as it contains no meat products. For a vegan version, you’d need to replace the eggs, dairy, and cheese with suitable alternatives.

What can I substitute for Gruyère or Swiss cheese?

You can swap it with other mild and melty cheeses like mozzarella, fontina, or even a sharp cheddar. Just keep in mind that different cheeses will slightly alter the flavor and texture.

Can I prepare the quiche filling ahead of time?

Yes! You can roast the squash and sauté the onions and sage a day ahead, then refrigerate them separately. Mix the custard and assemble the quiche right before baking for the freshest taste and texture.

How do I know when the quiche is fully cooked?

The quiche is done when the custard in the center is set and slightly jiggly but not liquid, and the top is a lovely golden brown. A small knife inserted in the middle should come out mostly clean.
