Smoke: Place 4 raw bratwursts on smoker grates and close lid. Let smoke until the internal temperature reaches 160℉, approximately 60-90 minutes.
Optional Reverse Sear: Alternatively you can let the brats smoke until they reach in internal temp of approximately 155℉ then turn the smoker all the way up and sear the brats on two sides for about 1 minute per side (the searing process could also be done on a gas grill for an even hotter sear).
Rest + Serve: Remove and let rest 5-10 minutes. Serve with buns of your choice and toppings of choice.
Notes
Raw vs. Pre-Cooked: if you are using pre-cooked brats instead of raw the recipe is the same just keep a closer eye on the internal temperature, it may not take as long to come up to temp.
Storage: store leftovers in the refrigerator in an airtight container for up to 3 days.
Serving: serve on your bun of choice with all your favorite toppings.
Wood Chips/Pellets: I love using mesquite, apple or hickory.
Traeger: I tested this on a Traeger grill, but it will work on any smoker.
