How to Make Butternut Squash Gratin With Onion And Sage

  1. Preheat oven to 350°F (175°C).
  2. Lightly butter a 9x13 inch gratin dish.
  3. In a large skillet, melt 2 tablespoons butter with 1 tablespoon olive oil over low heat.
  4. Add 2 medium yellow onions, thinly sliced, and 2 teaspoons fresh sage, chopped.
  5. Cover and cook, stirring occasionally, until onions are softened, about 10 minutes.
  6. While onions cook, prepare the butternut squash: Cut off the neck of a medium butternut squash (about 3 pounds), peel, and cut into 1-inch pieces. Reserve the bottom for roasting (optional).
  7. Steam the squash pieces in a steamer basket over simmering water for 10-12 minutes, or until tender.
  8. In the prepared gratin dish, combine the steamed squash with 2 cloves garlic, minced, and ¾ teaspoon salt.
  9. Toss gently to combine.
  10. Continue cooking the onions, stirring frequently, until deeply caramelized, about 20-25 minutes total. Season with salt and pepper to taste.
  11. Add the caramelized onions to the gratin dish and mix with the squash.
  12. Pour 1 ½ cups heavy cream over the vegetables.
  13. In a small bowl, combine ½ cup breadcrumbs with 2 tablespoons melted butter. Sprinkle evenly over the gratin.
  14. Bake for 35-40 minutes, or until the top is golden brown and bubbly.
