Ingredients
- 500 g ground beef (7030 lean-to-fat ratio)
- 100 g shredded mozzarella cheese
- 2 slices cheddar cheese
- 2 strips bacon
- 2 burger buns
- 1 tbsp butter
- 2 tbsp mayonnaise
- 1 tbsp ketchup
- 1 tbsp chopped pickles
- 2 leaves fresh lettuce
- 2 slices tomato
- to taste salt
- to taste black pepper
- optional cherry tomatoes for garnish
Instructions
- 1Melt the butter

Heat a non-stick frying pan over medium heat and add a small knob of butter. Allow the butter to melt completely until it begins to sizzle and coat the bottom of the pan. This provides a rich, savory base that will enhance the flavor of both the buns and the meat.
Tip: Keep the heat at medium to prevent the butter from browning too quickly or burning. - 2Toast the buns

Place the burger bun halves cut side down into the pan with the melted butter. Toast them until the surfaces are golden brown and slightly crispy to prevent the bread from becoming soft.
Tip: Watch the buns closely as they can transition from golden to burnt in a matter of seconds. - 3Prepare the burger sauce

In a small prep bowl, combine mayonnaise and ketchup with a portion of finely chopped pickles. The acidity of the pickles and the sweetness of the ketchup will cut through the richness of the beef patties, creating a balanced and tangy flavor profile for your burger.
Tip: Stir the mixture thoroughly until the color is uniform and the ingredients are fully integrated. - 4Season the beef

Add a generous amount of salt and freshly ground black pepper to the raw ground beef. Using a 7:3 lean-to-fat ratio ensures the burger remains juicy and flavorful. Seasoning at this stage allows the spices to be integrated during the mixing process, enhancing the natural meat aroma.
Tip: For the best texture, stir the meat in one direction only to develop a springy, cohesive mixture. - 5Stuff the patties

Flatten a portion of the seasoned beef in your palm and place a generous handful of shredded mozzarella cheese in the center. Carefully fold the edges of the meat over the cheese and pat it gently to seal it completely, ensuring the cheese is trapped inside to create a lava center.
Tip: Make sure the meat is sealed tightly with no visible cracks so the cheese doesnt leak out during frying. - 6Sear the patties and bacon

Heat the skillet and melt another knob of butter. Carefully place the mozzarella-stuffed beef patties and the bacon strips into the pan. Fry the bacon until it reaches your desired crispiness, then remove it while the patties continue to sear.
Tip: Starting with a hot pan and butter ensures the meat sears quickly, helping to lock in juices and preventing the cheese from leaking out too early. - 7Monitor the cheese lava

Continue frying the patties on both sides until they develop a deep brown, caramelized crust. Look for the mozzarella cheese starting to ooze out from the center—this is the sign that the cheese lava is perfectly melted and ready. Adjust the heat if necessary to ensure the meat is cooked through without burning the exterior.
Tip: If the exterior is perfectly browned but you want to ensure the cheese is fully molten, you can briefly cover the pan with a lid for 30 seconds to trap residual heat. - 8Top with cheddar cheese

As the beef patties finish cooking, place a square slice of yellow cheddar cheese on top of each one. The residual heat from the meat will naturally melt the cheese, creating a gooey, creamy layer that perfectly complements the savory beef and the hidden mozzarella core.
Tip: If you want the cheese extra melty, you can put a lid on the pan for about 30 seconds. - 9Assemble the final burger

Spread the sauce on both toasted buns. Layer the bottom bun with lettuce and tomato then stack the beef patties and bacon before adding the top bun to finish.
Tip: Insert a long skewer through the center of the burger to keep the massive stack stable during presentation.
