• Preheat your grill or skillet to a medium high heat (about 375-400°F).
• In a large bowl, combine the beef, Worcestershire sauce, salt, pepper, onion powder, garlic, 2 ½ tablespoons bourbon and the BBQ sauce. Use clean hands to gently mix until everything is just incorporated. (Overmixing will create a tough burger so be gentle.) Cover the mixture with plastic wrap and let it sit for 15 minutes to allow the flavors to meld.
• Form the meat into 4, evenly sized patties.

Grill

• Grill them on your grill, flipping halfway through. If your grill is 400°F you should grill on each side for 4 minutes for a medium burger. (See the burger cook times below for more details.)

Skillet or Grill Pan

• If you don’t have a grill, you can make these burgers on a large heavy bottom skillet. Add a bit of olive oil or butter into the skillet to prevent the meat from sticking and cook over medium high heat.
• While the burgers cook, make the cheese sauce. Stir together the remaining bourbon with the queso cheese in a small pot over low heat or in a microwave for 1 minute until warmed.
• Toast buns in oven if desired. Assemble your burgers by layering lettuce and then tomato. Next add burger patty, drizzle the cheese over the top and add bacon.. Top with the burger top and serve warm. Burger grilling times for 400 °F grill. These times will vary depending on burger hickness and grill consistency.
