Main Ingredients
- 2 pounds butternut squash (2 to 2 1/2 pounds or 4 cups cooked squash)
- ¼ cup whole milk
- 1 teaspoon vanilla extract
- 1 cup granulated sugar (or brown sugar, packed)
- ¼ teaspoon salt
- ⅔ cup unsalted butter (melted)
- ¼ teaspoon ground cinnamon
- 2 large eggs (lightly beaten)
Topping Ingredients
- 1 cup pecan halves
- 2 tablespoons unsalted butter (melted)
- 2 tablespoons brown sugar (packed)
- ⅛ teaspoon ground cinnamon
- Marshmallows (large or small optional)
How to Make Butternut Squash Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line a baking sheet with parchment paper or aluminum foil. Set aside.
Step 2: Prepare the Butternut Squash
Cut the butternut squash in half lengthwise. Scoop out the seeds and discard them. Place the squash cut side down on the prepared baking sheet. Bake for about 45 minutes or until tender when pierced with a fork. Allow it to cool enough to handle.
Step 3: Mix Ingredients
Lightly spray a casserole dish with vegetable cooking spray. While still warm, scoop out the butternut flesh into a large mixing bowl. Discard the skin/shell. Mash the squash using a potato masher or food processor until no chunks remain. Add the milk, vanilla extract, sugar, melted butter, and cinnamon; stir until combined. Incorporate the lightly beaten eggs by folding together or processing until blended—it’s okay if a few lumps remain.
Step 4: Bake the Casserole
Pour the mixture into your prepared baking pan. Bake until almost set for about 30 minutes. While baking, prepare your topping if you’re using one.
Step 5: Add Topping
In a small bowl, combine pecans, melted butter, brown sugar, and cinnamon; stir until coated. Remove the baking dish from the oven and sprinkle this mixture over the squash layer. Continue baking until set for about 15 more minutes.
Step 6: Toast Marshmallows (Optional)
If you are adding marshmallows, cook for an additional 45 minutes before removing from the oven. Top with marshmallows while preheating your oven broiler on high. Toast until melted and browned—watch carefully as this happens quickly! Serve immediately and enjoy your Butternut Squash Casserole!

How to Perfect Butternut Squash Casserole
Making the perfect butternut squash casserole involves attention to detail and some simple techniques. Follow these tips for the best results!
-
Choose Ripe Squash: Look for firm butternut squash without blemishes. A ripe squash will have a sweet flavor when cooked.
-
Cook Thoroughly: Ensure the squash is tender before mashing. This ensures a smooth texture in your casserole.
-
Taste Before Baking: Give your mixture a quick taste test before baking. Adjust sweetness or seasoning as needed.
-
Use Fresh Ingredients: Fresh spices and real butter can greatly enhance the overall flavor profile of your casserole.
-
Don’t Overmix: Mix just until combined. A few lumps add character and texture to your dish.
Best Side Dishes for Butternut Squash Casserole
Butternut squash casserole shines as a side dish, but it pairs wonderfully with several other options. Here are some ideal accompaniments to round out your meal:
-
Green Bean Almondine: Sautéed green beans topped with toasted almonds provide crunch and freshness.
-
Roasted Brussels Sprouts: Caramelized Brussels sprouts offer a savory contrast that balances the sweetness of the casserole.
-
Garlic Mashed Potatoes: Creamy mashed potatoes infused with garlic create a comforting addition that everyone loves.
-
Stuffing: A herbed stuffing brings earthy flavors that harmonize well with butternut squash.
-
Honey Glazed Carrots: Sweet carrots drizzled with honey add vibrant color and sweetness to your plate.
-
Cauliflower Rice: For a lighter option, serve cauliflower rice seasoned with herbs for a low-carb alternative that won’t overpower the main dish.
Common Mistakes to Avoid
When making a Butternut Squash Casserole, it’s easy to overlook a few key steps. Here are some common mistakes to avoid for a perfect dish.
- Not Using Fresh Squash: Always opt for fresh butternut squash instead of canned. Fresh squash provides better texture and flavor.
- Skipping the Cooling Step: Allow the baked squash to cool slightly before mashing. This prevents burns and helps achieve a smoother consistency.
- Overmixing: Be careful not to overmix the casserole mixture. A few lumps can enhance the texture, so mix just until combined.
- Ignoring Oven Temperature: Ensure your oven is correctly preheated to 350°F. An incorrect temperature can lead to uneven cooking.
- Forgetting the Topping: If you want a crunchy topping, don’t skip it! Prepare your pecan or marshmallow topping while the casserole bakes.
