two hands holding up burger on bun with lettuce, tomatoes and onion


  • 4 lbs Beef, Ground
  • 1 Loaf Bread, Sourdough Round
  • 1/2 Cup Butter
  • Condiments (Ketchup, Mustard, Relish, etc.)
  • Lettuce
  • 3 Cups Mushroom
  • 3 Onion, Chopped
  • 1 lbs Pork, Ground
  • Red Onion, Chopped
  • 1 Bag Shredded Cheddar Cheese
  • Tomato, Sliced

Special Tools

  • Large mixing bowl


  1. Start your Grill on ''smoke'' with the lid open until a fire is established in the burn pot (3-4 minutes). Preheat to 300°F.
  1. In a large bowl, mix together the ground beef, ground pork, eggs, Pit Boss Kansas City Maple & Molasses BBQ Sauce, and Sweet Heat Rub until combined. DO NOT over mix as this will cause the meat to be tough after cooking. Split the mixture into two equal parts.
  1. Melt the butter in a pan over medium heat and sauté the onion mushrooms until golden.
  1. In a cast iron pan, flatten one half of the meat mixture into the bottom, taking care to work meat slightly up the sides of the pan. Sprinkle in half of the bag of cheese. Pour in onion mixture and top with the rest of the cheese.
  1. On a clean work surface, mold the second half of the meat mixture into a circle and cover the filling to complete the burger. Make sure that the top and bottom meat patties are secured together so that the filling cannot be seen.
  1. Place the cast iron pan in the Grill for 1 hour - 1 hour 15 minutes, or until the internal temperature reaches 160°F. Crank up the to ''HIGH'' and open the flame broiler. Flip the burger out of the cast iron pan onto the grates and sear each side for 5 minutes, to get those beautiful grill marks.
  1. To serve You can make an enormous burger like we did, or you can cut it like a pie into slices to be served on regular hamburger buns with your desired condiments.
