Thick, juicy bacon cheeseburgers stacked with crispy bacon and melted American cheese are a high protein family cookout favorite. Nothing beats this classic American burger for a satisfying, carnivore-friendly meal.
Preheat grill or a large skillet over medium-high heat; arrange bacon slices in a single layer and cook until deeply crispy, about 4–5 minutes per side. Drain on paper towels.
While bacon cooks, gently form the ground beef into 4 equal patties, about 3/4-inch thick. Season both sides with kosher salt and black pepper, pressing lightly for even distribution.
Place the burgers onto the hot grill or skillet. Cook for 3–4 minutes on the first side (medium-high heat), flip once, and lay one slice of American cheese on each patty immediately after flipping.
Continue cooking until cheese melts and burgers reach your preferred doneness, about 3–4 additional minutes for medium; rest burgers off direct heat for 3 minutes to retain juiciness.
Split buns and toast on the grill for 1–2 minutes until golden. Spread mayo and ketchup on the bottom bun, then layer lettuce, tomato slices, red onion, cheeseburger patty, and two bacon slices. Top with the bun and serve.
