Step 1

Preheat oven to 350 degrees Cook pasta according to package directions. I recommend cooking the pasta a minute less than the directions. Drain and set aside for a few minutes.

Step 2

To prepare roux, melt butter into a medium saucepan over medium heat. Once melted whisk in flour, salt and pepper. Stir and cook for 3-4 minutes until color of roux gets slightly darker. Slowly whisk in milk, stirring continuously until thickened, about 2 minutes. Reduce heat to a simmer and stir in 2 cups of cheese until melted.

Step 3

Transfer cooked pasta to 12-inch cast iron skillet over low heat. Pour cheese sauce over top, stirring to combine.

Step 4

Top mac and cheese with remaining 1 cup of shredded cheese, crushed crackers and bacon pieces. Bake for 20-25 minutes until cheese is melted and hot. Serve warm.
