Prepare the ingredients. 1. Finely dice the onion. 2. Mix the breadcrumbs with the milk.

For the breadcrumbs, it's recommended to use panko, which is Japanese-style breadcrumbs, because they are larger and crunchier. You can find it in any supermarket in the international foods section.

Add a tablespoon of oil to a pan and heat.

Add the onion and sauté over low heat for 10 minutes. Let it cool slightly.

In a bowl, mix the ground beef, cooked onion, breadcrumbs with milk, egg, salt, and black pepper.

Mix well by hand (about 50 times).

This is how the meat should look after mixing.

Divide the meat into 4 pieces and shape into oval, flat patties with your hands.

Press the center to make it thinner, as the center takes longer to cook.

Add a tablespoon of oil to a pan and heat.

Place the patties in the pan and cook over medium heat for 3 minutes on each side without covering.

Lower to low heat and add 2 tablespoons of water. Cook for another 3 minutes on each side with the lid on.

Insert a toothpick, and if clear white juice comes out, the hamburger is ready. (If the juice is not clear and red, cook a little longer.)

Prepare the sauce. In the same pan where the hamburger was cooked, mix the red wine, ketchup, and Worcestershire sauce, and cook over low heat.

Serve the hamburgers with the sauce and enjoy!
