Instructions
Roast the butternut squash:
Heat oven to 375℉. Cut the squash in half lengthwise and remove the seeds. Place the squash skin side down on a lightly greased baking sheet pan and drizzle with olive oil. Place in the oven and cook until the squash is soft all the way through, about 1 hour. Set aside until cool. When cooled, remove the skin and place it in a food processor. Purée until smooth.
Make cheese sauce:
Melt butter in a saucepan over medium heat. Whisk in the flour and stir to make a roux - cook it for 3 minutes, stirring the entire time. Add 3 cups of milk and stir until thickened. Add the rest of the milk and bring to a boil, stirring occasionally.
When the sauce reaches a boil and is thicker, remove it from the heat and stir in the shredded cheeses. Stir until melted. Stir in salt, pepper, and dried herbs.
To assemble the dish:
Preheat the oven to 350℉.
Place the cooked macaroni in a large bowl. Pour in the cheese sauce and add the puréed butternut squash. Gently stir and fold together the pasta, sauce, and squash puree.
Spread the mixture in a large 9x13" ovenproof dish and heat for 20 minutes until it is hot through and slightly bubbly.
