Start by dividing the 1 pound of 80/20 ground beef into four equal portions. Gently shape each portion into a patty, making a slight indentation in the center to prevent it from puffing up while cooking. Season both sides generously with coarse salt and freshly cracked pepper.
Place your skillet or frying pan over medium-high heat. Add a drizzle of oil to the pan to prevent sticking. Allow the oil to heat until shimmering.
Carefully place the burger patties in the hot skillet. Cook for about 3-4 minutes on one side without moving them, allowing a nice crust to form. Flip the patties and immediately place a slice of American cheese on each one. Continue cooking for another 3-4 minutes, or until the cheese is melted and the burgers reach your desired doneness.
In a separate pan, melt 2 tablespoons of unsalted butter over medium heat. Crack an egg into the pan, being careful not to break the yolk. Season with a pinch of salt and pepper. Fry until the whites are set but the yolk remains runny, about 2-3 minutes. Repeat this process for the remaining eggs.
While the eggs are frying, cut the hamburger buns in half and toast them in the skillet until golden brown. This adds an extra layer of flavor and prevents the buns from becoming soggy.
Start by spreading a generous amount of burger sauce on the bottom half of each toasted bun. Layer with a red leaf lettuce leaf, followed by the cheesy beef patty. Top with a fried egg, a few slices of red onion, tomato, and pickles. Finish with the top half of the bun.
