Shred all your cheese, roast, and prep jalapenos, cook, and chop bacon, and cook pasta.
Pre-heat smoker to 225 degrees.
In a large pot, melt butter. Add in flour and whisk consistently for 2-3 minutes. Slowly pour in half & half. Whisk as you are pouring. Bring to a simmer. Taste and add salt and pepper.
Once the mixture thickens up, add in half of the bacon and jalapenos and cream cheese. Stir till melted.
Turn heat to low. Add in half of the Colby Jack, all the pepper jack and parmesan. Stir till melted and thick. Taste and add salt and pepper if necessary. Turn the heat off.
To a large deep dish, baking pan or aluminum foil pan, add cooked pasta and the cheese mixture. Stir till everything is combined.
Place onto smoker and cook for 30 minutes uncovered. (If using an aluminum foil pan place a baking sheet underneath to support the weight)
At 30 minutes, stir. Top with remaining Colby Jack, bacon, and jalapenos. Cook for another 30 minutes.
Pull dish off smoker and let it rest for 10 minutes.
Enjoy!
