How to Make Butternut Squash Casserole

Step 1: Prepare the squash

Start by peeling and cubing your butternut squash into roughly 1-inch pieces to ensure even cooking. Then boil or steam the cubes until tender but not mushy, about 10-15 minutes.

Step 2: Sauté aromatics

In a skillet, melt butter over medium heat and add finely chopped onions and minced garlic. Cook until soft and fragrant, about 5 minutes, which builds the flavorful base of your casserole.

Step 3: Mash and mix

Once your squash is cooked, mash it lightly with a fork or potato masher, leaving some chunks for texture. Stir in the sautéed onions and garlic, then gently fold in heavy cream, shredded cheddar cheese, salt, pepper, and fresh herbs until combined.

Step 4: Assemble and top

Transfer the mixture into a greased baking dish. Evenly sprinkle panko breadcrumbs over the top to create a crunchy, golden crust as it bakes.

Step 5: Bake to perfection

Bake your casserole at 375°F (190°C) for 25-30 minutes until the top is crispy and the inside is heated through and bubbly.

Pro Tips for Making Butternut Squash Casserole

• Choose fresh squash: Fresh butternut squash has a sweeter, more vibrant flavor than pre-cut or frozen.
• Don’t over-mash: Keep some texture in the squash for a more interesting bite and better mouthfeel.
• Toast breadcrumbs: Lightly toast breadcrumbs before topping to enhance crunchiness.
• Use sharp cheddar: Sharp cheddar cheese melts better and adds richer flavor.
• Let it rest: After baking, let the casserole sit 5 minutes before serving to set up nicely.
