Ingredients

• 4 cups butternut squash (peeled, seeded, and cubed)
• 2 tablespoons olive oil
• 1 medium yellow onion (finely diced)
• 3 garlic cloves (minced)
• 1 teaspoon fresh thyme (chopped)
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 0.5 cups grated Parmesan cheese
• 1 cups shredded Gruyere cheese
• 0.75 cups heavy cream
• 1 cups panko breadcrumbs
• 2 tablespoons butter (melted)
• 2 tablespoons fresh parsley (chopped, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Step 2

Spread the cubed butternut squash on a baking sheet. Drizzle with 1 tablespoon of olive oil, and sprinkle with a pinch of salt and pepper. Toss to coat. Roast in the preheated oven for 20-25 minutes or until tender.

Step 3

While the squash is roasting, heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and sauté for 5 minutes until translucent.

Step 4

Stir in the minced garlic and fresh thyme, and cook for another minute until fragrant.

Step 5

Once the squash is cooked, transfer it to the skillet with the onions, and gently mash it with the back of a spoon or potato masher, leaving some chunks for texture.

Step 6

Mix in the heavy cream, Parmesan cheese, and half of the shredded Gruyere. Season with 1 teaspoon of salt and 1/2 teaspoon of black pepper. Stir well to combine.

Step 7

Pour the mixture into the prepared baking dish, spreading it into an even layer.

Step 8

In a small bowl, combine the panko breadcrumbs with melted butter. Sprinkle the breadcrumb mixture evenly over the casserole. Top with the remaining shredded Gruyere cheese.

Step 9

Bake in the oven for 20 minutes until the topping is golden and bubbly.

Step 10

Remove from the oven and let it cool for 5 minutes. Garnish with fresh parsley before serving. Enjoy!
