Ingredients
- 4 burger buns with sesame
- 400 grams ground beef
- 200 g Gouda slices (4 slices)
- 160 g Romaine lettuce (1 head of lettuce)
- 1 onion
- 24 g parsley (3 sprigs)
- 1 egg yolk
- 1 teaspoon white vinegar
- 1 1/2 teaspoons mustard
- 10 tablespoons sunflower oil
- 1 red onion
- 2 tomatoes
- 2 tablespoons breadcrumbs
- 4 tablespoons tomato ketchup
- Salt
- Ground pepper
Preparation
- 1Finely chop the white onion. Wash and dry the parsley, remove the leaves, and finely chop them as well. Then slice the red onion into fine rings and set aside. For the sauce, whisk together 1 teaspoon of mustard, vinegar, egg yolk, salt, and pepper. Afterward, gradually add 8 tablespoons of sunflower oil while continuously stirring. Then stir in half of the already chopped onions and half of the chopped parsley.
- 2Now vigorously knead the ground beef with 1 tablespoon of mustard, breadcrumbs, salt, pepper, and the remaining half of the diced onions, then form into 4 patties. Heat 2 tablespoons of sunflower oil in a pan and fry the patties for 8 to 10 minutes, turning regularly.
- 3Wash and dry the lettuce. Also wash the tomatoes and slice them. Then cut the burger buns horizontally and toast them beforehand. Now place the romaine lettuce on the bottom, already toasted burger bun. Layer the patty on top of this. Place a slice of Gouda on this patty. Then arrange the ketchup and red onion rings together with the mixed sauce. Place the tomato slice on top, to finally finish with the top half of the bun.
Tip
The optimal thickness for burger patties is about 2 centimeters. With this thickness, they cook quickly and remain wonderfully juicy.
