1. Start by cooking the chopped bacon in a large skillet over medium heat until crisp. Use a slotted utensil to remove the bacon and set it aside on a paper towel-lined plate, leaving the bacon fat in the pan.

2. Add the thinly sliced onion to the bacon fat and stir to coat. Reduce the heat to medium-low and cook the onions until they are tender and golden, about 25-30 minutes, stirring occasionally.

3. Meanwhile, in a large bowl, combine the ground beef, Worcestershire sauce, mustard, garlic powder, Old Bay seasoning, salt, pepper, and the reserved crispy bacon pieces. Mix the ingredients gently until just combined, being careful not to overwork the meat.

4. Divide the bacon burger mixture into 4 equal portions and flatten each one into a 1-inch thick patty.

5. Once the onions are golden, create a well in the center of the pan and pour in the bourbon. Stir the onions and bourbon together for about 30 seconds, then pour in the maple syrup and stir to combine. Remove the caramelized onions from the skillet and set them aside. Carefully wipe the skillet clean.

6. Heat the olive oil in the clean skillet over medium-high heat. Place the bacon burger patties into the skillet, leaving space between each one. Cook for 4-5 minutes per side, until they reach your desired doneness.

7. During the last minute of cooking, top each burger patty with a slice of cheddar cheese. Cover the skillet with a lid to allow the cheese to melt.

8. Transfer the cheeseburger patties to a clean plate and let them rest for a few minutes.

9. Assemble the Loaded Bourbon Maple Bacon Cheeseburger Melt by placing the patties on lightly toasted buns. Top them with the maple bourbon caramelized onions, lettuce, tomatoes, and any desired condiments, such as mayonnaise or mustard.
