Ingredients
Scale
- 2 medium butternut squash (about 3 pounds total), peeled, seeded, and thinly sliced into 1/8-inch thick rounds or half-moons
- 2 tablespoons unsalted butter
- 1 small yellow onion, minced
- 2 cloves garlic, minced
- 2 cups heavy cream
- 1/2 cup whole milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon freshly grated nutmeg
- 1 cup shredded Gruyere cheese, divided
- 1/2 cup grated Parmesan cheese, divided
- 8–10 fresh sage leaves, whole
Instructions
- Preheat your oven to 375°F and lightly butter a 9×13 inch baking dish.
- In a large saucepan, melt the butter over medium heat. Add minced onion and cook until softened, about 5 minutes. Stir in minced garlic for an additional minute.
- Pour in heavy cream and milk, bringing it to a gentle simmer. Reduce heat, then stir in salt, pepper, and nutmeg. Remove from heat and mix in half of the Gruyere and Parmesan cheeses until smooth.
- Layer one-third of the sliced butternut squash in the baking dish, followed by one-third of the cream sauce and some cheese. Repeat until all ingredients are used, finishing with cheese on top and tucking sage leaves among the layers.
- Cover tightly with foil and bake for 45 minutes. Uncover and bake for another 20-30 minutes until golden brown and bubbly; broil for an extra few minutes if desired.
- Let rest for 10 minutes before serving.
