Line a rimmed baking sheet with aluminum foil. This step will make cleanup much easier. Place a wire rack in the baking sheet.
Place the bacon on the wire rack making sure they don't overlap.
Place the baking sheet in the preheated oven and cook for 15-20 minutes or until the bacon is golden brown and crispy.
Carefully remove the bacon from the oven and transfer it to a plate lined with paper towels to absorb any excess grease.
Buns
Lightly spread a layer of butter on each cut side of the burger bun. Make sure to spread it all the way to the edges.
On a griddle over medium-high heat put the buttered side of the buns down and allow them to cook for about 1-2 minutes or until they are a golden brown.
Burger
Shape the ground beef into four equal-sized burger patties that are slightly bigger than the buns. Lightly salt and pepper each patty (both the bacon and blue cheese are salty). Refrigerate for 10-15 minutes.
While the patties are being chilled in the refrigerator, preheat your grill or stovetop griddle over medium-high heat.
Grill the burger patties to your desired level of doneness, usually about 4-5 minutes per side for medium-rare. During the last minute of grilling, add a generous portion of blue cheese crumbles on top of each patty and cover with a lid.
Remove the patties from the heat and let them rest.
Burger Assembly
Spread mayonnaise on the bottom half of each burger bun.
Place a lettuce leaf on top of the mayo. Add a slice of tomato, a burger patty with melted blue cheese, and a slice of crispy bacon.
Cover each burger with the top half of the burger bun. Enjoy with your favorite side dishes or a salad.
