Butternut Squash Mac and Cheese Recipe

  • 1 butternut squash, halved lengthwise and seeded
  • 1 (16 ounce) package rotini pasta
  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 1/2 teaspoon dry mustard
  • 2 cups milk
  • 6 ounces shredded white Cheddar cheese
  • 6 ounces shredded Cheddar cheese
  • 1/4 cup seasoned dry bread crumbs, or as needed
  1. Preheat oven to 400 degrees F (200 degrees C).
  2. Place butternut squash, cut-side down, on a baking sheet.
  3. Roast squash in the preheated oven until soft, 40 to 50 minutes. Remove squash flesh from skin and set aside. Reduce oven temperature to 375 degrees F (190 degrees C).
  4. Bring a large pot of lightly salted water to a boil; cook the rotini at a boil until tender yet firm to the bite, about 8 minutes; drain.
  5. Melt butter in a large saucepan over medium heat. Whisk flour and mustard into melted butter until smooth, about 1 minute. Gradually whisk milk into flour mixture until the mixture has the texture of heavy cream, 5 to 7 minutes. Remove from heat.
  6. Stir butternut squash, white Cheddar cheese, and Cheddar cheese into milk mixture until cheese is melted. Stir rotini into cheese mixture. Pour cheese mixture into a 9×13-inch baking dish. Top with bread crumbs.
  7. Bake in the preheated oven until bread crumbs are golden, about 10 minutes.
