- 1 pound ground beef (ground chuck is perfect)
- 2 tablespoon olive oil

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!
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.
