In a skillet over medium heat, cook the bacon until crispy. Remove and place on paper towels to drain excess grease.
02 -
In the same skillet, remove excess bacon grease, leaving just enough to coat the pan. Add the sliced onions and cook until soft and caramelized, about 10–15 minutes. Pour in the Irish stout and simmer until the liquid reduces by half. Season with salt and pepper. Set aside.
03 -
In a bowl, mix the ground beef with Worcestershire sauce, salt, and pepper. Form into 4 equal patties, making them slightly larger than the buns as they will shrink while cooking.
04 -
Heat a grill or skillet over medium-high heat. Cook the patties for about 3–4 minutes per side for medium-rare, or to your preferred doneness. In the last minute of cooking, top each patty with grated cheddar cheese, allowing it to melt.
05 -
In a small bowl, combine the sour cream, Dijon mustard, and a pinch of salt. Mix well. Set aside.
06 -
In a pan, melt a small amount of butter and toast the burger buns until golden brown.
07 -
Place a cheeseburger patty on the bottom half of each toasted bun. Top with caramelized onions, two slices of crispy bacon, and a generous dollop of the sour cream sauce. Cover with the top bun.

Serve the assembled burgers immediately with fries or chips on the side.
