It started with your typical google search yesterday. I found a couple of good recipe's and did a few little twists. The inspiration came from a post on smokingmeatforums.com, but I can't find it now unfortunately.
Amazing! Going to try a different cheese combination with crab next.
Here's the basic recipe if you want to give it a try.
2 cups elbow macaroni
1 stick butter (next cook I may reduce down to half a stick)
3 cups milk
2 cups heavy whipping cream
1 package shredded cheddar cheese (the ones you see at the grocery store, 8oz I believe)
1 package combination of colby and monterey jack cheese cubes (same as above 8oz I believe)
salt and pepper
Put the dry (uncooked) macaroni elbows in a pan (somewhere around 9x13 size)
Melt a stick of butter, and then pour it over the macaroni
Add cheddar cheese
Add colby and monterey jack cheese
Add milk
Add heavy whipping cream
Salt and pepper to taste
Give it a stir (I actually stirred it another time or two during the early cooking process).
Into the smoker at 250 degrees for approximately 1:50 minutes (I did 1:54 to be exact)
Save a little of the shredded cheddar when you're preparing, and add a layer on top now (after the 1:50 in the smoker).
Into the oven on broil for a few minutes until you get the desired color you're looking for
Smokey, creamy, noodles done to perfection. This is a good one.
Enjoy
