6 Servings
Ingredients
For the Squash:
- 6 tbsp unsalted butter
- 2 1/2 to 3 pounds acorn squash halved and seeded
- 1/4 c packed light brown sugar
- 1/4 c maple syrup
- 1/2 tsp ground cinnamon
- 1/2 tsp fine salt
- 1/4 tsp ground nutmeg
For the Crumble Topping:
- 1 c all-purpose flour
- 1 c packed light brown sugar
- 1/4 tsp fine salt
- 10 tbsp unsalted butter cold and cut into cubes
- 3/4 c roughly chopped walnuts
Instructions
To Make the Squash:
- Start by preheating your oven to 350°F. Grab an 8x8-inch baking dish and give it a good coating with baking spray—this will save you some cleanup later!
- Next, melt the butter in a small saucepan over medium-low heat. As it melts, you’ll notice it starting to foam and sizzle around the edges. Keep stirring every now and then, and after about 2-3 minutes, you’ll see it turn a beautiful golden brown. Once it reaches that perfect color, pour it into a heat-safe bowl and set it aside for now.
- Now, grab a microwave-safe dish and pop your acorn squash in. Microwave it for 8-12 minutes, depending on your microwave's power, until it’s soft and cooked through. Carefully remove the skin—this can be a little tricky if it's hot, so be careful! Cut the squash into smaller pieces and toss them into a bowl. While it’s still warm, mash it up until it’s mostly smooth. If you like a super smooth texture, you can always blend it or use a food processor.
- Once the squash is mashed, stir in the browned butter, brown sugar, maple syrup, cinnamon, salt, and nutmeg. Mix it well, then transfer the squash mixture to your greased baking dish.
To Make the Crumble Topping:
- In a separate bowl, mix together the flour, brown sugar, and salt. Now, take your cold butter cubes and cut them into the flour mixture. You want to keep mixing until the butter is fully incorporated and the mixture starts to resemble coarse crumbs.
- Stir in the chopped walnuts until everything is evenly mixed.
- Sprinkle the crumble topping over the squash mixture. Pop the dish into the oven and bake for about 25-30 minutes, or until the topping is golden brown and the edges of the casserole are bubbling. Let it cool just slightly before serving, and enjoy it while it's still warm and cozy!
Notes
If you’re looking to make this Comforting Browned Butter Squash Casserole gluten-free, it’s super simple! All you need to do is swap the all-purpose flour in the crumble topping for a gluten-free flour blend. Most gluten-free blends will work just fine here, especially the ones that are labeled “1:1” or “cup-for-cup.” They’ll give you the same crumbly, buttery topping without the gluten. Everything else in the recipe is naturally gluten-free—acorn squash, butter, brown sugar, maple syrup, and walnuts—so once you make that easy swap, this dish becomes a perfect gluten-free option for everyone to enjoy!
