Ingredients

• 2 pounds winter squash or rutabaga
• 1 cup heavy cream
• 0.5 cup whole milk
• 2 pieces garlic cloves
• 1 teaspoon fresh thyme
• 0.5 cup grated Parmesan cheese
• 0.5 cup grated Gruyère cheese
• 2 tablespoons unsalted butter
• 1 teaspoon salt
• 0.5 teaspoon freshly ground black pepper
• 0.25 teaspoon nutmeg (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Peel the winter squash or rutabaga and slice it thinly into rounds about 1/8-inch thick using a sharp knife or a mandoline.

Step 3

In a small saucepan, combine the heavy cream, whole milk, minced garlic cloves, and fresh thyme. Heat the mixture over low heat until warm but not boiling. Remove from heat and set aside.

Step 4

Butter an 8x8-inch (or similar size) baking dish with 1 tablespoon of unsalted butter.

Step 5

Arrange a single layer of squash or rutabaga slices at the bottom of the dish, slightly overlapping. Sprinkle lightly with salt, pepper, and a pinch of grated nutmeg (if using).

Step 6

Pour a small amount of the warmed cream mixture over this layer and sprinkle with a portion of both the Parmesan and Gruyère cheeses.

Step 7

Repeat layering squash/rutabaga slices, cream mixture, and cheese until all the ingredients are used, finishing with a layer of cheese on top.

Step 8

Dot the top layer with the remaining tablespoon of butter for added richness.

Step 9

Cover the dish tightly with foil and bake for 40 minutes in the preheated oven.

Step 10

Remove the foil and bake uncovered for an additional 15-20 minutes, or until the top is golden brown and the squash/rutabaga is tender when pierced with a knife.

Step 11

Allow the gratin to cool for 5-10 minutes before serving to let the flavors settle. Serve warm and enjoy!
