Ingredients
- 400 g beef
- 2 onions
- 2 tsp rock sugar
- 1 tsp white granulated sugar
- 1 egg
- 2 slices cheese
- 2 burger buns
- 1 tomato
- 2 lettuce leaves
- 2 potatoes
- 1 tbsp olive oil
- 1 tsp apple cider vinegar
- to taste salt
- to taste black pepper
- to taste oregano
- to taste garlic powder
Instructions
- 1Caramelize the Sugar Base

Place the rock sugar and white granulated sugar into a pan over low heat. Slowly melt the sugars until they reach a deep, golden, caramelized state.
Tip: Keep the heat low to ensure the sugar melts evenly without burning. - 2Caramelize the Onions

Add the pre-cut onions to the caramelized sugar mixture along with a little olive oil, apple cider vinegar, and a pinch of salt. Stir well and simmer slowly over low heat until the onions are perfectly caramelized.
Tip: Caramelized onions add a sweet and savory depth that is essential for a great burger. - 3Prepare the Beef

Finely mince the beef using a cleaver on a cutting board to ensure a tender texture.
Tip: Even though this beef has less fat, hand-mincing helps maintain a good texture for the patties. - 4Season and Bind

In a mixing bowl, combine the minced beef with salt, black pepper, oregano, garlic powder, olive oil, and the egg. Mix thoroughly and refrigerate the mixture for a short time to firm up before shaping.
Tip: Refrigerating the meat mixture helps it hold its shape better during cooking. - 5Shape the Patties

Take the meat mixture and form it into large balls, about 200 grams each. Use your hands to gently flatten each ball into a patty shape suitable for frying.
Tip: Ensure the patties are uniform in size for even cooking. - 6Cook and Melt Cheese

Place the patties into a hot pan and fry until cooked through. Once flipped and cooked, top each patty with a slice of cheese, then immediately turn off the heat to let the residual warmth melt the cheese perfectly.
Tip: If the meat is too moist, it can be tricky to flip; make sure the pan is sufficiently hot before placing the patty in. - 7Add cheese to the patties

Once the beef patties are fully cooked in the hot pan, place a slice of cheese on top of each patty. Immediately turn off the heat, allowing the residual heat to perfectly melt the cheese over the meat.
Tip: Do not overcook the meat once the cheese is added; the residual heat is enough to melt it without drying out the burger. - 8Parboil the potato sticks

Place the prepared potato sticks into a pot of boiling water. Boil them for approximately 5 minutes, then drain the water thoroughly to prepare them for freezing and subsequent baking.
Tip: Parboiling ensures the fries are soft on the inside while becoming crispy in the oven. - 9Assemble the burger

Place the cooked beef patty with melted cheese onto the bun. Add the homemade caramelized onions, fresh tomato slices, and crisp lettuce leaves. Top it off to finish the burger.
Tip: Layering the ingredients in this order helps keep the burger stable and ensures a balance of flavors in every bite.
