Cut the bacon into pieces and freeze the pieces for 20 minutes to make it easier to process.
Process the bacon in a mini food processor on the "chop" setting until finely ground. Mix it into the beef with the remaining ingredients.
Form the mixture into four ¾-inch-thick patties. Use your thumb to make a shallow dimple in the middle of each burger. This helps them retain their shape.
Heat a well-seasoned cast-iron skillet over medium heat, about 3 minutes. Add the burgers. If the skillet is well-seasoned, there's no need to add oil. Otherwise, add a tablespoon of oil to the pan before adding the burgers.
Cook the burgers until cooked through, about 4-5 minutes per side over medium heat.*
Serve immediately with your favorite hamburger toppings.**
* If you’d like to ensure that the bacon inside the patties is fully cooked, you can par-cook it in the microwave.In this method, there’s no need to chop and freeze it. Place the four strips on two paper towels on a microwave-safe plate; cover with two more paper towels; microwave for three minutes, allow to slightly cool, then chop and mix into the ground beef.** Nutrition info is for the burgers only and does not include toppings.
