Caramelized Onion Burgers
- Divide the ground beef into 3 equal sections and gently form them into rounds. Press each round firmly with a flat object, like the bottom of a plate, to form into patties. Season generously with salt and black pepper.
- Set a large skillet over medium-high and add cooking oil. Once the oil is shimmering add burger patties, cooking in batches if needed. Cook until a brown crust forms on the bottom and the top is beginning to turn a deep red. Flip patties, top with cheese, and cook for a few minutes longer, until the cheese melts.
- Lightly toast the buns, then spread Balsamic Mayo on the inside of the hamburger buns. Add burger patty to the buns and top with ~2 tablespoons caramelized onions per burger, or to taste.
- Let the burgers rest briefly to allow juices to redistribute, then serve and enjoy!
Notes
When making caramelized onions for this recipe, I recommend using 2 large yellow onions and 1 ½ tablespoons of butter.
You can also make this as fast-food-style smash burgers by using thin hamburger patties.
