Preheat your Yoder Smokers YS640 to 375ºF. Preheat a cast iron skillet in the cooker. Reserve two slices of bacon, then dice and cook the rest in the skillet. Remove the diced bacon and set aside. Add the onions, mushrooms, beer and House of Q House BBQ Rub. Cook until liquid is gone and mushrooms and onions are softened.
Turn the cooker down to 275ºF. Form two (1/2 lb) balls with the 80/20 ground beef. Press a beer can into the center of the ball and form a sort of bowl around the bottom of the can. Remove the can from the meat. Season the beef with House of Q House BBQ Rub. Wrap around the side of each bowl one of the reserved slices of bacon.
Add the fillings to the inside of the “bowl,” including half of the swiss cheese (torn into pieces). When the burger is filled to the top with the bacon, swiss, mushrooms and onions, top each burger with one whole slice of swiss.
Smoke the burger until the internal temperature reaches 160ºF. Use a digital thermometer to accurately monitor the internal temperature. While the burger smokes you can toast your ciabatta buns. Serve the burger dressed with the lettuce and Big Rick’s Chipotle Ketchup.
