Why You Will Love This Butternut Squash Casserole:
- Simple to make. Roast the squash in halves for easy prep—no boiling and minimal peeling required.
- Balanced sweetness. Brown sugar and butter give a pleasant sweetness that complements savory mains.
- Can double as a dessert. Top with vanilla ice cream for a cozy dessert twist.
- Make-ahead friendly. Prepare a day ahead and reheat before serving to save time on the big day.
Recipe Ingredients:
- butternut squash: Roast a whole squash halved, or use precut squash to save time. To halve a squash easily, microwave 1–2 minutes to soften, then cut and scoop seeds.
- butter: salted or unsalted (unsalted preferred)
- milk: whole milk gives the creamiest texture; 2% or a dairy-free milk will also work
- brown sugar: light or dark
- eggs: large
- cinnamon: a warm hint; optionally add nutmeg, ginger, or cloves
- vanilla: use real vanilla extract for best flavor
- sea salt: to balance flavors
- flour: all-purpose works; a 1:1 gluten-free flour can substitute in the topping
- pecans: for the crumble; swap walnuts or almonds if preferred, or omit for nut-free
Step-By-Step Instructions:
Roasting the squash is the longest step, but you can do it ahead to streamline assembly on the day you bake the casserole.
- Preheat oven to 375°F. Halve the squash lengthwise and scoop out the seeds. Place halves face down on a parchment-lined baking sheet and roast about 45 minutes, until tender.
- Let the squash cool slightly, then scoop the flesh into a bowl and mash until smooth.
- Stir in melted butter, brown sugar, eggs, milk, vanilla, salt, and cinnamon until well combined. For extra creaminess, beat with a mixer.
- Butter or grease a 9×9-inch baking dish and spread the squash mixture evenly in the pan.
- In a small bowl, mix the topping ingredients (butter, flour, brown sugar, pecans, vanilla, and a pinch of salt) until crumbly.
- Spread the crumble evenly over the squash layer. Bake at 350°F for 40–45 minutes, until the topping is golden and the filling has set.
- Let cool about 10 minutes before serving.
Recipe Tips
- Serve warm or cold. Both are delicious—choose whichever you prefer.
- Time-savers: Use pre-cut squash or canned squash if you’re short on time.
- Make ahead: Assemble and refrigerate a day in advance, then reheat before serving or serve at room temperature.
- Gluten-free option: Use a 1:1 gluten-free all-purpose flour for the topping.
Storage:
Store leftovers in an airtight container in the refrigerator for 4–5 days. Reheat in a 350°F oven 7–10 minutes or microwave until warm.
This casserole freezes well. Cool completely, transfer to a freezer-safe container, and freeze up to 3 months. Thaw in the refrigerator for 24 hours before reheating.
Ways to Vary This Recipe:
- Add fresh or dried cranberries to the crumble for a tart contrast.
- Swap the pecans for chopped walnuts or sliced almonds, or omit nuts for a nut-free version.
- Boost the spice: add nutmeg, allspice, or ginger along with cinnamon for deeper warm notes.
