Thanksgiving Leftover Mac and Cheese

1 . Stage

Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally, until tender yet firm to the bite, about 8 minutes. Drain pasta, then rinse with cold water and drain again. Set aside.

2 . Stage

While the pasta is cooking, melt 1 1/2 tablespoons butter in a skillet over medium heat. Add onion and saute until translucent, 5 to 7 minutes. Add garlic and cook until fragrant, 1 to 2 minutes. Add carrots and celery; saute until soft, 3 to 5 minutes. Add leftover turkey and cook until warm and flavors are incorporated, about 1 minute. Season with parsley, sage, rosemary, thyme, salt, and pepper. Add broth if mixture seems dry. Remove from the heat and set aside.

3 . Stage

Melt remaining butter in a large saucepan over medium (or slightly higher) heat. Whisk in flour; cook, whisking constantly, until the mixture becomes paste-like and light golden brown, 2 to 3 minutes. Whisk in milk (about 1 to 2 tablespoons); keep stirring to make sure flour is blended and there are no lumps. Cook until roux is brown and very fragrant. Add Cheddar, Monterey Jack, Gouda, and Parmesan cheeses; cook until sauce thickens and the cheese melts. Slowly add enough milk so the roux/cheese mix is creamy; just add it in small increments so it's not too juicy.

4 . Stage

Add macaroni to the cheese sauce and mix to combine. Add the turkey mixture. Mix well and transfer to a baking dish. Top with bread crumbs.

5 . Stage

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.

6 . Stage

Place mac and cheese under the broiler until browned, 5 to 10 minutes.
