Buffalo Chicken Mac and Cheese blends spicy buffalo flavor with creamy cheddar sauce and tender pasta, baked with a golden crunchy topping that finishes it just right.
Preheat the oven to 350 degrees. Melt the butter in a medium saucepan over medium-high heat. Add the onion and cook for 3 minutes, or until onion is translucent and butter has browned.
Add the flour, salt, and pepper to the onion mixture and whisk, cooking for 2-3 minutes.
Gradually pour the milk and hot sauce into the flour mixture, whisking constantly. Cook and stir over medium heat until slightly thick and bubbly. Stir in the chicken and cheese until melted.
Add the cooked macaroni to the cheese sauce and stir to coat.
Transfer the macaroni and cheese mixture to a 2-quart casserole and sprinkle with bread crumbs and blue cheese crumbles (if using).
Bake, uncovered, for 30 minutes or until cheese sauce is bubbly and heated through. Let stand for 10 minutes before serving.
