🥘 Ingredients

14 items

• 1 medium-sized (about 2 pounds) butternut squash
• 8 cups (loosely packed) fresh spinach
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups milk
• 1 cup heavy cream
• 1 cup (grated) parmesan cheese
• 1.5 cups (grated) gruyere cheese
• 1 teaspoon (or to taste) salt
• 0.5 teaspoon (freshly ground) black pepper
• 0.25 teaspoon ground nutmeg
• 0.75 cup panko breadcrumbs
• 1 tablespoon olive oil
• 2 cloves (minced) garlic

📝 Instructions

13 steps

1. Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or cooking spray.

2. Peel the butternut squash, then slice into thin rounds (about 1/8-inch thick). Set aside.

3. In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the minced garlic and sauté for 30 seconds, stirring frequently to prevent burning.

4. Add the fresh spinach to the skillet and cook for 2-3 minutes, until wilted. Remove from heat and set aside.

5. In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1 minute to create a roux.

6. Gradually pour in the milk and heavy cream, whisking constantly to avoid lumps. Cook the sauce for 3-4 minutes until it thickens.

7. Turn off the heat and stir in the grated parmesan cheese (1 cup) and 1 cup of the grated gruyere cheese, reserving 0.5 cup for the topping. Mix until the cheese has melted into the sauce. Season with salt, black pepper, and ground nutmeg.

8. In the prepared baking dish, layer half of the sliced butternut squash, followed by half of the cooked spinach. Pour half of the cheese sauce over the vegetables.

9. Repeat the layers with the remaining squash, spinach, and cheese sauce.

10. In a small bowl, combine the panko breadcrumbs, the reserved 0.5 cup of grated gruyere cheese, and 1 tablespoon of olive oil. Sprinkle this mixture evenly over the top of the gratin.

11. Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.

12. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and bubbling.

13. Let the gratin rest for 5-10 minutes before serving. Enjoy this creamy and cozy dish as a side or main course!
