Instructions

Making this delicious butternut squash casserole is incredibly simple with these step-by-step instructions. Each stage is designed to be beginner-friendly, ensuring a perfect result every time. Follow along closely for a creamy, flavorful dish that will impress your guests.

1. Prep Oven & Squash: Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or aluminum foil; this makes cleanup a breeze. Cut the butternut squash in half lengthwise and scoop out all the seeds and fibrous bits, discarding them. Place the squash halves cut-side down on your prepared baking sheet.
2. Roast Squash: Bake the squash for approximately 45 minutes, or until it’s fork-tender. The roasting process helps deepen the flavor and makes the squash easier to handle. Allow the roasted squash to cool slightly before moving to the next step.
3. Prepare Casserole Base: Lightly spray your casserole dish with vegetable cooking spray and set it aside. While still warm, scoop the soft butternut squash flesh into a large mixing bowl, discarding the skin. Mash the squash thoroughly with a potato masher, or process it in a food processor until it’s smooth. Add the milk, vanilla extract, granulated sugar, melted butter, and ground cinnamon to the mashed squash. Stir these ingredients together until they are well combined. Finally, fold in the lightly beaten eggs until just blended. A few small lumps are perfectly fine for this flavorful squash casserole.
4. Initial Bake: Pour the butternut squash mixture evenly into your prepared casserole dish. Bake for about 30 minutes, or until the casserole is almost set in the center. The edges should start to look slightly firm.
5. Prepare Topping (Pecans): While the butternut squash casserole is baking, prepare your delicious pecan topping. In a small bowl, combine the pecan halves, two tablespoons of melted butter, two tablespoons of packed brown sugar, and ⅛ teaspoon of ground cinnamon. Stir everything together until the pecans are fully coated.
6. Add Pecan Topping & Finish Bake: Carefully remove the casserole dish from the oven. Sprinkle the prepared pecan mixture evenly over the partially baked squash base. Return the dish to the oven and continue baking for another 15 minutes, or until the casserole is fully set and the topping is golden brown and slightly caramelized.
7. Optional Marshmallow Topping: If you prefer a marshmallow topping, bake the casserole for the initial 45 minutes until cooked through and set. Remove it from the oven and arrange large or small marshmallows over the top. Preheat your oven broiler on high. Return the casserole to the oven and broil the marshmallow topping until it’s melted and golden brown. Watch it very carefully, as marshmallows can brown and burn quickly under the broiler. Serve your irresistible butternut squash casserole immediately for the best experience.

Pro Tips & Troubleshooting

Achieve the best possible butternut squash casserole with these helpful tips and avoid common pitfalls.

• Selecting Squash: Choose a butternut squash that feels heavy for its size, firm to the touch, and free of blemishes. For guidance on choosing the best squash for your recipe, refer to expert tips on identifying a perfectly ripe butternut squash.
• Roasting Method: Roasting the squash initially enhances its natural sweetness and makes it much easier to scoop out the flesh.
• Mashing Consistency: Decide if you prefer a completely smooth casserole by using a food processor, or a slightly chunky texture with a potato masher.
• Prevent Watery Casserole: Ensure you don’t overcook the squash initially, as too much moisture can lead to a watery dish.
• Even Baking: Use the correct size casserole dish (a 2-quart dish is ideal) to ensure the casserole bakes evenly throughout.
• Topping Placement: Adding the topping after an initial bake prevents it from sinking into the squash mixture, maintaining its crunchy texture.

Serving Suggestions, Storage, & Variations

This versatile butternut squash casserole makes a delightful addition to many meals.

Serving Suggestions

• Serve it alongside classic holiday main dishes like roasted turkey, spiral-cut ham, or a juicy baked chicken.
• It pairs beautifully with other festive sides such as green bean casserole, mashed potatoes, or cornbread dressing.
• Enjoy this comforting dish as a standalone vegetable side for a cozy weeknight meal.

Storage

• Store any leftover butternut squash casserole in an airtight container in the refrigerator for up to 3-4 days.
• To reheat, gently warm portions in the oven at 300°F (150°C) until heated through, or use the microwave for individual servings.

Make Ahead & Freezing

• Make Ahead: Prepare the squash base mixture up to 24 hours in advance. Cover the casserole dish tightly with plastic wrap and refrigerate. Before baking, allow it to come to room temperature for about 30 minutes. Then, bake as directed and add the topping.
• Freezing: While possible, freezing this holiday squash side might alter its texture slightly upon thawing, making it a bit grainier. For the best results, we generally recommend enjoying it fresh or only refrigerating leftovers.

Flavor Variations

• Spices: Amp up the flavor with a pinch of nutmeg, ground ginger, or a dash of allspice.
• Sweetness: For a less sweet option, reduce the granulated sugar, or use a natural sweetener like maple syrup or honey.
• Savory Twist: Omit the sugar entirely, and add savory herbs like fresh sage or thyme, along with a touch of garlic powder.
• Crunchy Topping: Instead of pecans, try a topping of crushed cornflakes or panko breadcrumbs mixed with butter and brown sugar.
• Citrus Notes: For a bright contrast, include a teaspoon of orange zest or a splash of fresh orange juice in the squash mixture.
