SWEET POTATO ACORN SQUASH AU GRATIN

Steps:

• Melt 2 tablespoons butter in a heavy saucepan over medium heat. Cook and stir onion and garlic in hot butter until onion is golden and soft, 5 to 10 minutes.
• Stir sweet potatoes, 1 3/4 cups cream, acorn squash, thyme, kosher salt, and pepper into onion mixture. Bring to a boil, reduce heat to low, and simmer until potatoes and squash are tender, 20 to 25 minutes.
• Preheat oven to 385 degrees F (195 degrees C). Butter an 8x13-inch baking dish with remaining butter.
• Pour potato-squash mixture into prepared baking dish. Drizzle remaining cream over potatoes and squash; top with bread crumbs and Asiago cheese. Cover baking dish with aluminum foil.
• Bake in the preheated oven until tender and hot throughout, 25 to 35 minutes. Remove aluminum foil and bake until top is golden brown, about 10 minutes more.
