Preheat your pellet smoker to 225°F, making sure to use a mild flavored pellet (we used applewood).

Bring a large pot of water to a boil and add the uncooked macaroni noodles and salt to the water and stir.

Let pasta cook until just under al dente. Strain noodles and set aside.

Next, prepare a roux by heating a large Dutch oven or cast iron skillet (use a Dutch oven or cast iron skillet so you can put the same pot on the smoker) over medium/high heat. Add butter.

When the butter is melted add flour and whisk until the butter and flour form a crumble.

 Slowly add milk to the pot, whisking constantly. Continue to whisk the roux over medium/high heat for about 4-6 minutes or until the roux thickens.

When the roux is thick, remove from heat and add the cheddar cheese. Whisk until the cheese has melted.

Add granulated garlic, hot sauce, and salt and pepper to the cheese sauce. Mix well.

Add the cooked macaroni noodles to the cheese sauce and mix until the noodles are covered in cheese sauce.

Sprinkle additional ½ cup cheese over the top.

Place on the smoker uncovered for 45 minutes - 1 hour, or until desired smokiness is achieved.

Enjoy immediately.
