Preparation Phase & Tools to Use
Before diving into making your Acorn Squash Casserole, it’s important to prepare your kitchen effectively. Start by gathering your ingredients and tools. You’ll need a large cutting board for the acorn squash, a sharp knife, mixing bowls of varying sizes, a measuring cup, and measuring spoons. A 9×13-inch baking dish will be essential for the casserole itself.
Make sure to preheat your oven to 425°F before you begin prepping the squash, as this step saves time. Carefully cut your acorn squashes in half and scoop out the seeds, making sure to leave as much flesh intact as possible for that creamy texture we want. A sturdy baking sheet lined with parchment paper will make for easy cleanup later on, and while the squash is roasting, you can prepare the pecan topping.

Ingredients
- 3 large acorn squash halved and seeded (yields 9–10 cups roasted squash)
- 1 tablespoon olive oil
- Kosher salt to taste
- 1/2 cup (100g) light brown sugar, packed
- 1/4 cup (30g) all-purpose flour (gluten-free if needed)
- 4 Tablespoons (56g) unsalted butter, melted
- 2 large eggs, beaten
- 1 teaspoon cinnamon
- 2 teaspoons vanilla extract
- 1/2 cup (8 Tbsp; 57g) unsalted butter, cut into cubes (for topping)
- 1 cup (200g) light brown sugar, packed (for topping)
- 1/2 cup (60g) all-purpose flour (gluten-free if needed, for topping)
- 1 3/4 cups raw pecans, roughly chopped
- 1 teaspoon kosher salt (for topping)
Instructions
Step 1: Roast the Acorn Squash
Begin by preheating your oven to 425°F. Cut the acorn squash in half, removing the seeds and stringy insides with a spoon. Brush the cut sides with olive oil, sprinkling them with kosher salt. Place the squash halves cut-side down on a baking sheet and let them roast in the oven for about 40–45 minutes until the flesh is tender when pierced with a fork.
Step 2: Prepare the Pecan Topping
While your squash roasts, melt 4 tablespoons of unsalted butter in a small saucepan over medium heat. Watch carefully as it foams and turns brown—this usually takes about 4-5 minutes. Once the butter has developed a nutty aroma and rich brown color, remove it from the heat. In a separate bowl, mix together the light brown sugar, flour, chopped pecans, and kosher salt. Stir in the browned butter carefully to create a crumbly topping. Set aside to cool.
Step 3: Create the Squash Mixture
After the squash has roasted and cooled slightly (around 10-15 minutes), scoop the flesh into a mixing bowl. Mash it well to achieve a smooth consistency, then mix in the brown sugar, flour, melted butter, beaten eggs, cinnamon, and vanilla extract. Taste the mixture and adjust the salt if necessary, adding a pinch more if you like it saltier.
Step 4: Assemble and Bake
Reduce your oven temperature to 350°F. Transfer the squash mixture to a 9×13-inch baking dish, spreading it evenly. Sprinkle the pecan topping generously over the top of the mixture. Bake in the preheated oven for an additional 35-40 minutes, or until the topping is golden brown and crisp. If the topping browns too quickly, cover it loosely with foil.

Variations
- Protein: For a heartier dish, consider adding shredded chicken or turkey to the squash mixture.
- Vegetables: Incorporate sautéed onions or spinach for added nutrition and a flavor boost.
- Spices: Feel free to spice it up with nutmeg or ginger for a warm, spiced autumn flavor.
Cooking Notes
- The acorn squash can be roasted ahead of time and stored in the refrigerator until you’re ready to prepare the casserole.
- If you’re looking for a gluten-free option, ensure that your flour and additional ingredients are certified gluten-free.
Serving Suggestions
- Pair this casserole with roasted meats like chicken or turkey for a festive touch.
- Serve with a simple green salad to compliment the rich flavors of the dish.
Tips
- To unlock an even deeper flavor, try toasting the pecans in a dry skillet before adding them to the topping.
- If you prefer a sweeter casserole, increase the amount of brown sugar in the mix or topping.
