Combine the ground beef, bacon, worcestershire sauce, salt and pepper in a large bowl.
Divide this mixture into 8 patties.
Flatten 4 of the patties and top each of those with ¼ cup shredded cheddar cheese.
Flatten out the other 4 patties and place them on top of the patties topped with the cheese. Crimp the edges of the hamburger patties together to form a seal around the cheese.
Place on a grill or in a skillet on the stove over medium heat. Grill for 6-8 minutes, flip and grill for an additional 6-8 minutes.
Toast the buns on the grill or skillet for 1-2 minutes.
Remove the burgers and place them on the buns, add the optional toppings of your choice.
Notes
Slightly freeze the bacon slices first, 30-60 minutes in the freezer will do. This will make the bacon easier to finely chop. You can also ask your butcher to grind the bacon for you.
If cooking these burgers in a skillet on the stove, use a cast iron skillet or other heavy bottomed skillet, if available.
These burgers are less than 1 carb per burger when served without the bun, making them low carb and keto compliant.
