Ingredients

• 2 pounds butternut squash
• 3 tablespoons olive oil
• 1 large yellow onion
• 3 large garlic cloves
• 1 tablespoon fresh thyme
• 1 tablespoon fresh sage
• 1 teaspoon kosher salt
• 0.5 teaspoons black pepper
• 1 cup bread crumbs
• 0.5 cup Parmesan cheese, grated
• 1 cup cheddar cheese, shredded
• 2 tablespoons unsalted butter
• 0.5 cup heavy cream

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Peel and seed the butternut squash, then cut it into 1-inch cubes. Toss the cubes with 2 tablespoons of olive oil, 1/2 teaspoon of kosher salt, and 1/4 teaspoon of black pepper. Spread the cubes on a baking sheet in a single layer and roast for 25 minutes, or until tender and slightly caramelized.

Step 3

While the squash is roasting, finely chop the yellow onion and mince the garlic cloves.

Step 4

Heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the onion and cook for 5-7 minutes, or until softened. Add the garlic, thyme, and sage, and cook for an additional 2 minutes, stirring frequently.

Step 5

Reduce the oven temperature to 375°F (190°C).

Step 6

Once the squash is finished roasting, transfer it to a large mixing bowl and lightly mash it with a fork or potato masher, leaving some chunks for texture. Stir in the onion and herb mixture.

Step 7

Add the shredded cheddar cheese, heavy cream, 1/4 cup of Parmesan, and the remaining salt and pepper to the squash mixture. Stir until well combined.

Step 8

Transfer the mixture to a greased 9x13-inch (or similarly sized) baking dish, smoothing it into an even layer.

Step 9

In a small bowl, mix the breadcrumbs, the remaining 1/4 cup of Parmesan, and melted butter until the breadcrumbs are evenly coated. Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 10

Bake the casserole at 375°F (190°C) for 20 minutes, or until the topping is golden brown and the casserole is bubbling around the edges.

Step 11

Allow the casserole to cool for 5 minutes before serving. Serve warm and enjoy a hearty, savory dish perfect for winter!
