Pumpkin Butternut Squash Pie

The first time I brought this savory pie to a Halloween potluck, my friends were genuinely confused. They were expecting something sweet, but the moment they tasted that first wedge of spiced, creamy goodness, plates started emptying fast. Now it is the one dish I am asked to bring every single autumn gathering without fail.

Last October, I made three of these pies back to back because my family kept requesting them for different occasions. My kitchen smelled like roasted squash and warm spices for days, which honestly is not a problem I mind having. Each one disappeared faster than the last, and I learned to always make extra because people go back for seconds.

Ingredients

• 2 cups butternut squash: Roasting this first concentrates the natural sweetness and gives the pie a better texture than raw squash would
• 1 cup pumpkin puree: Use pure pumpkin, not pie filling, since we are building our own spice profile here
• 1 medium onion: Finely chopped so it melts into the filling rather than staying chunky
• 2 cloves garlic: Mince these fresh because garlic powder just does not give the same punch
• 1 cup baby spinach: Chopped small so it distributes evenly throughout each slice
• 3 large eggs: Room temperature eggs incorporate better into the filling mixture
• 1 cup whole milk or heavy cream: Heavy cream gives a richer result, but whole milk works perfectly fine
• 1 cup shredded Gruyere or sharp cheddar cheese: Gruyere adds that nutty sophistication, but sharp cheddar brings more familiar comfort vibes
• 1 9-inch savory pie crust: Homemade is lovely but a good store-bought crust saves time and tastes excellent
• 1/2 teaspoon ground cumin: This earthy spice is what makes the pie feel savory rather than sweet
• 1/2 teaspoon smoked paprika: Adds a subtle smoky depth that plays beautifully with the roasted squash
• 1/4 teaspoon nutmeg: Just enough to hint at autumn warmth without overwhelming the other flavors
• 1/2 teaspoon dried thyme: Fresh thyme works too, just use about 1 tablespoon instead
• 1/4 teaspoon black pepper: Freshly cracked gives the best aroma and flavor
• 1/2 teaspoon salt: Adjust this depending on how salty your cheese is
• 2 tablespoons olive oil: Divided between roasting the squash and sautéing the vegetables
• 1 tablespoon fresh sage: Optional, but if you have it, this makes the whole kitchen smell like fall

Instructions

Roast the butternut squash:

Preheat your oven to 375°F and spread the diced squash on a baking sheet, drizzle with 1 tablespoon olive oil, season with salt and pepper, then roast for 20 to 25 minutes until tender and slightly caramelized at the edges.

Sauté the aromatics:

Heat the remaining olive oil in a skillet over medium heat, cook the onion until translucent about 4 minutes, add garlic for 1 minute, then stir in spinach until just wilted.

Make the custard base:

Whisk together eggs, milk or cream, cumin, paprika, nutmeg, thyme, pepper, and salt until completely combined and smooth.

Combine everything:

Fold the pumpkin puree, roasted squash, sautéed vegetables, cheese, and sage into the egg mixture until all the fillings are evenly distributed.

Prepare the crust:

Press your pie crust into a 9-inch pie pan, trim any overhanging edges, and crimp the border however you like for that homemade look.

Fill and bake:

Pour the filling into the crust, smooth the top, and bake for 35 to 40 minutes until the center is set and the top has turned this gorgeous golden brown.

Rest before serving:

Let the pie cool for at least 10 minutes so the filling sets properly, then slice and serve warm or at room temperature.

Save

My cousin actually called me the day after Thanksgiving demanding this recipe because she could not stop thinking about the leftovers she had taken home. Something about the way the smoked paprika and Gruyere play together just sticks with people. Now every time I see her, she asks if I am bringing the squash pie.

Make It Ahead

This pie actually tastes better the next day once the flavors have had time to get to know each other properly. You can assemble the entire thing, refrigerate it overnight, and bake it fresh the next morning. Just add about 5 to 10 minutes to the baking time if it is cold going into the oven.

Serving Ideas

I love serving this with a simple arugula salad dressed with lemon vinaigrette because the brightness cuts through the richness of the custard. A side of roasted Brussels sprouts or sautéed kale also feels very autumn appropriate. For Halloween parties, I have been known to cut small wedges and serve them as appetizers.

Customization Options

Sometimes I swap in kale for the spinach when I want something with a bit more texture and bite. Goat cheese instead of Gruyere gives the pie a tangier, more sophisticated edge. If you want to make it heartier, you can even add cooked crumbled sausage or bacon.

• Try adding roasted pumpkin seeds on top for extra crunch
• A pinch of cayenne pepper creates a lovely warm kick
• Fresh thyme can replace dried if you have it growing in your garden

There is something deeply satisfying about serving a pie that looks like dessert but tastes like a proper meal. This one has become my secret weapon for autumn entertaining.

Recipe Questions & Answers

→ Can I make this ahead of time?

Yes, prepare the entire pie one day in advance and store it covered in the refrigerator. Reheat gently at 300°F for about 15-20 minutes before serving to maintain the creamy texture.

→ What can I substitute for Gruyère cheese?

Sharp cheddar works beautifully and provides a stronger flavor profile. Swiss cheese offers a milder alternative, while aged Gouda brings a nutty sweetness that complements the squash.

→ Is fresh pumpkin necessary or can I use canned?

Canned unsweetened pumpkin puree works perfectly fine and saves preparation time. Just ensure it's plain pumpkin rather than pumpkin pie filling, which contains added spices and sugar.

→ How do I know when the pie is done?

The pie is finished when the edges are set and golden brown, but the center still has a slight jiggle—similar to a custard. It will continue to firm up as it cools during the resting period.

→ Can I freeze this pie?

Yes, freeze the fully baked pie once completely cooled. Wrap tightly in plastic and foil for up to 3 months. Thaw overnight in the refrigerator before reheating in a 350°F oven until warmed through.

→ What vegetables work well as additions?

Kale, Swiss chard, or diced bell peppers can enhance the filling. For earthy notes, try adding sautéed mushrooms or roasted Brussels sprouts. Keep additions to about 1 cup total to maintain proper filling consistency.
