How to Make Easy Butternut Squash Casserole Recipe
Step 1: Prepare the squash
Start by preheating your oven to 375°F and lightly greasing a 9×13 inch baking dish—this is where the magic happens. Next, bring a large pot of water to a boil and cook the peeled and cubed butternut squash for about 12 to 15 minutes. You’re aiming for squash that’s fork-tender but not falling apart. Once cooked, drain it really well and mash it until it’s completely smooth. This step is essential for that creamy, comforting texture that defines the casserole.
Step 2: Mix the base
In a large bowl, combine the mashed butternut squash with melted butter, granulated sugar, lightly beaten eggs, whole milk, vanilla extract, salt, cinnamon, and nutmeg. Make sure to mix everything until it becomes smooth and creamy. This silky mixture forms the heart of your casserole, packed with cozy, inviting flavors.
Step 3: Assemble the casserole
Spread your luscious squash mixture evenly into the prepared baking dish. This even layer is necessary to ensure every bite is perfectly balanced between the creamy base and the crunchy topping you’re about to add.
Step 4: Make the topping and bake
In a small bowl, stir together the brown sugar, chopped pecans, and flour. This trio creates a delightfully sweet and crunchy topping that beautifully contrasts with the smooth squash layer. Sprinkle this mixture evenly over the squash base, then pop the casserole into your preheated oven. Bake for 40 to 45 minutes or until the center is set and the topping turns a gorgeous golden brown. After baking, let it cool for about 10 minutes to allow the flavors to meld perfectly before serving.
How to Serve Easy Butternut Squash Casserole Recipe

Garnishes
To add an extra touch of charm and flavor, consider garnishing your casserole with a few fresh herbs like chopped parsley or thyme. A light drizzle of maple syrup or a sprinkle of toasted pumpkin seeds can also add an elegant twist that brightens each serving.
Side Dishes
This casserole shines as a side dish alongside roasted turkey, glazed ham, or even a simple green salad dressed with a tangy vinaigrette. It pairs beautifully with dishes that have subtly savory or herbaceous profiles, making your meal well-rounded and satisfying.
Creative Ways to Present
For festive occasions, serve the casserole in individual ramekins for a charming, personal touch. You can also layer it in a clear glass casserole dish to show off the contrast between the creamy squash and the crunchy topping. Adding a sprinkle of extra pecans on top just before serving not only looks appealing but amps up the texture too.
Make Ahead and Storage
Storing Leftovers
Once your Easy Butternut Squash Casserole Recipe has cooled completely, cover it tightly with plastic wrap or transfer leftovers to an airtight container. Store in the refrigerator for up to four days. The flavors actually deepen overnight, making it a perfect make-ahead side dish.
Freezing
If you want to enjoy this casserole later, it freezes beautifully. Assemble the casserole but don’t bake it. Wrap it tightly in plastic wrap and aluminum foil, then freeze for up to three months. When ready to enjoy, thaw it overnight in the refrigerator and then bake as directed, adding a few extra minutes if needed.
Reheating
Reheat individual portions in the microwave or warm the entire casserole in the oven at 350°F until heated through. To keep the topping crisp, try reheating uncovered or briefly broil for a minute or two at the end. This way, every bite stays just as delightful as when it was freshly baked.
FAQs
Can I use roasted squash instead of boiled?
Absolutely! Roasting the squash at 400°F for about 25 minutes adds a deeper, caramelized flavor and can make the casserole even richer. Just be sure to mash it smooth like you would with boiled squash.
Is this recipe suitable for vegans?
This specific recipe isn’t vegan-friendly due to the butter, eggs, and milk, but you can swap these with plant-based alternatives such as vegan butter, flaxseed eggs, and almond or oat milk to make a delicious vegan version.
Can I substitute sweet potatoes for butternut squash?
Yes, sweet potatoes make an excellent substitute! They offer similar sweetness and texture, and the casserole will still be wonderfully creamy with that classic fall flavor profile.
How many servings does this casserole provide?
This recipe yields about 8 generous servings, making it perfect for family dinners or holiday gatherings where everyone wants seconds.
What’s the best way to achieve a crispy topping?
Using a mixture of brown sugar, chopped pecans, and flour ensures a crunchy, caramelized topping. Baking uncovered and allowing the casserole to cool slightly before serving helps lock in that crisp texture.
