1-First step: Mix the burger patties Place the 500 g minced beef, 30 g panko breadcrumbs, 1 egg, 1 tablespoon Worcestershire sauce, 1 tablespoon ketchup, 1 teaspoon sea salt flakes, and 0.5 teaspoon black pepper into a large bowl. Use your hands or a spoon to combine everything until just mixed. Try not to overwork the meat, because that can make the patties dense. The mixture should hold together without feeling tough.

2-Second step: Shape the patties Divide the mixture into 4 to 6 portions, depending on how large you want the burgers. For a standard family meal, 4 patties usually work best. Shape each portion into a round patty, then press a small indent into the center with your thumb. This little dip helps the burgers cook evenly and keeps them from bulging in the middle. A thumb indent may seem small, but it makes a big difference when you want flat, juicy burgers.

3-Third step: Heat the pan Pour 2 tablespoons olive oil into a large frying pan and set it over medium-high heat. Let the oil get hot before adding the patties. If you are cooking for someone who prefers less oil, use a good nonstick pan and brush the surface lightly instead. The aim is to get a nice browned crust without burning the outside.

4-Fourth step: Cook the burgers Carefully place the patties into the hot pan. Cook for 10 to 12 minutes total, turning them once halfway through. If the pan looks dry near the end, add up to 2 tablespoons water during the last 2 minutes. The steam helps finish the center gently. For food safety, beef burgers should be cooked to a safe internal temperature, so use a thermometer if you have one.

5-Fifth step: Toast the rolls and prep the toppings While the patties cook, split the 4 brioche rolls and toast them lightly. Prep the 4 slices gouda cheese, 2 sliced tomatoes, 1 sliced red onion, lettuce leaves, and 2 tablespoons sliced gherkins. Set out 4 teaspoons whole-egg mayonnaise, 4 teaspoons ketchup, and 4 teaspoons American mustard so everyone can build their own burger just the way they like it.

6-Final step: Assemble and serve Place each cooked patty on a toasted brioche roll. Add a slice of gouda cheese, then top with tomato, red onion, lettuce, and gherkins. Finish with mayonnaise, ketchup, and American mustard. Serve right away while the burgers are hot and the cheese starts to soften over the top.
