Halloween Pumpkin Butternut Squash Pie

The first time I brought this pumpkin and butternut squash pie to a Halloween potluck, my friend Jen actually texted me the next morning begging for the recipe. She said her usually picky toddler had eaten two slices and asked for thirds, which still feels like my greatest kitchen victory to date. Theres something about the way the sweetness of pumpkin mingles with savory roasted squash that just makes people comfortable and happy.

Last autumn, I made this pie on a rainy Sunday afternoon while my housemate decorated the living room with paper bats and orange twinkle lights. The whole house filled with the smell of roasting squash and sage, and when we finally sat down to eat it with mulled cider, it felt like the most perfect cozy moment. Now it is not officially Halloween at our place until this pie comes out of the oven.

Ingredients

• 2 cups butternut squash, peeled and diced: Roasting the squash first concentrates its natural sweetness and creates a creamy texture that blends beautifully with the pumpkin
• 1 cup pumpkin puree (unsweetened): Make sure to use pure pumpkin puree, not pie filling, so you control the sweetness and spices yourself
• 1 medium onion, finely chopped: Sautéing the onion until it is translucent adds a subtle sweetness that balances the earthy squash
• 2 cloves garlic, minced: Fresh garlic gives a aromatic backbone that enhances all the other flavors
• 1 cup baby spinach, chopped: The spinach wilts down into the filling, adding color and nutrients without overwhelming the dish
• 3 large eggs: Room temperature eggs will incorporate more evenly into the custard filling
• 1 cup whole milk or heavy cream: Heavy cream makes for a richer pie, but whole milk works beautifully if you are watching the fat content
• 1 cup shredded Gruyere or sharp cheddar cheese: Gruyere adds a nutty sophistication while cheddar brings a familiar sharpness both work wonderfully here
• 1 9-inch savory pie crust: Homemade is lovely, but a good quality store bought crust saves time and bakes up just as flaky
• 1/2 teaspoon ground cumin: A pinch of cumin adds an earthy warmth that makes the pie feel more complex
• 1/2 teaspoon smoked paprika: This is the secret ingredient that gives the pie a subtle smoky depth
• 1/4 teaspoon nutmeg: Just enough nutmeg to hint at pumpkin pie vibes without making it taste like dessert
• 1/2 teaspoon dried thyme: Thyme bridges the gap between the sweet pumpkin and savory elements perfectly
• 1/4 teaspoon black pepper: Freshly ground pepper adds a little bite that wakes up all the flavors
• 1/2 teaspoon salt: Enhances all the other flavors and balances the natural sweetness of the vegetables
• 2 tablespoons olive oil: Use this for roasting the squash and sautéing the aromatics
• 1 tablespoon fresh sage, chopped (optional): Fresh sage adds an unmistakable autumn flavor that makes the whole house smell amazing

Instructions

Get your oven going:

Preheat to 375°F (190°C) and position a rack in the middle of the oven for even baking.

Roast the butternut squash:

Toss the diced squash with one tablespoon olive oil, salt and pepper on a baking sheet, then roast for 20 to 25 minutes until fork 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 one more minute, then stir in spinach until wilted.

Whisk the custard base:

In a large bowl, whisk together eggs, milk or cream, cumin, smoked paprika, nutmeg, thyme, pepper and salt until fully combined.

Combine everything:

Fold in the pumpkin puree, roasted butternut squash, sautéed vegetables, shredded cheese and fresh sage if using, mixing until all the filling ingredients are evenly distributed.

Prepare the crust:

Roll out your pie crust and gently press it into a 9-inch pie pan, trimming any overhang and crimping the edges for a pretty finish.

Fill and bake:

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

Rest before serving:

Let the pie cool for at least 10 minutes so the filling sets properly this slice will hold its shape much better.

Save

My grandmother used to say that a recipe is not really yours until you have made it your own, and this pie has become one of those staples I cannot imagine autumn without. The year I moved into my first apartment, I made it for my new neighbors and we ended up eating it on cardboard boxes while sharing stories about our families. That night, this pie stopped being just a recipe and became part of my own story.

Make It Your Own

Substitute kale for the spinach or swap in Swiss cheese for the Gruyere, and you will still end up with something delicious. The beauty of this pie is that it is forgiving and adaptable, much like the best comfort food should be.

Serving Suggestions

This pie shines alongside a crisp green salad with vinaigrette to cut through the richness. For a complete Halloween dinner, pair it with roasted Brussels sprouts or a warm grain salad.

Storage & Reheating

The pie keeps beautifully in the refrigerator for up to four days and actually develops more flavor overnight. To reheat, cover with foil and warm in a 325°F oven until heated through.

• Sprinkle roasted pumpkin seeds on top before baking for added crunch
• Make mini versions in muffin tins for party friendly appetizers
• Freeze the unbaked pie for up to two months and bake straight from frozen

There is something deeply satisfying about serving a dish that looks impressive but comes together with such humble ingredients. Wishing you the happiest of autumn feasts.

Recipe FAQs

→ Can I make this pumpkin butternut squash pie ahead of time?

Yes, this pie can be prepared a day in advance. Store it in the refrigerator and reheat gently at 300°F for 15-20 minutes before serving. The flavors actually develop and improve overnight.

→ What cheese works best in this savory autumn pie?

Gruyere offers excellent meltability and nutty flavor, but sharp cheddar provides a bolder taste. Fontina, Swiss, or aged Gouda also work beautifully. Choose a cheese that melts well and complements the earthy squash.

→ Can I use fresh pumpkin instead of puree?

Absolutely. Roast small pie pumpkins at 400°F for 45-60 minutes until tender, scoop out the flesh, and puree until smooth. One small pumpkin yields about 2 cups of puree. Drain excess moisture for best results.

→ How do I know when the pie is done baking?

The pie is finished when the center is set and no longer jiggly when gently shaken. The top should be golden brown, and a knife inserted near the center should come out clean. The internal temperature should reach 160°F.

→ Can I freeze this butternut squash pie?

Freeze before baking by assembling the pie, wrapping tightly in plastic and foil, and freezing for up to 3 months. Bake from frozen, adding 10-15 minutes to the baking time. Already-baked pie can be frozen but may have slightly altered texture.

→ What can I substitute for spinach in this recipe?

Kale, Swiss chard, or chopped broccoli rabe make excellent substitutes. Sauté them briefly as you would the spinach. For a green-free version, simply increase the butternut squash or add diced bell peppers.
