Directions

Step 1: Cook the pasta

Preheat the oven to 350°F. In a large stockpot, cook the pasta according to the package directions. Drain the pasta and put it back in the pot.

Step 2: Add the other ingredients

Combine the three shredded cheeses, setting aside four cups of cheese for the topping.

Over low heat, stir the cheeses and remaining ingredients (butter, milk, ketchup, mustard, brown sugar, onion, garlic, thyme, ground pepper, salt and hot pepper sauce) into the pasta until everything is well combined and the cheese begins to melt.
