5th Step
Immediately sprinkle a good amount of the caramelized onions over the top of each of the crushed patties. As the meat continues to cook, give them a chance to combine with the flesh.
6th Step
Toast the hamburger buns with a little melted butter in a separate frying pan until they reach a color somewhere between golden and light brown. While the patties are still cooking on the griddle, you may top each one with a piece of cheese if you so like. To facilitate the melting of the cheese, cover the pan with a lid.
7th Step
Put some of your favorite toppings on the bottom of each toasted bun. Place a burger on top of the onions, then caramelize them. You may top your sandwich with lettuce, tomatoes, pickles, or any other ingredients you choose. Put the top half of the bread on it, and serve it while it’s still hot
