Loaded Italian Sausage and Beef Smash Burgers

Remove the casing from the Italian sausage. Thoroughly mix the ground beef and Italian sausage together in a bowl. Divide the mixture into 4 equal balls, about 125g each. Season the outside of each ball generously with salt.

Heat a heavy cast-iron skillet or flat-top griddle over high heat until smoking. Melt half of the butter. Place the meat balls onto the hot surface, leaving plenty of space between them. Immediately press down incredibly hard with a heavy spatula or grill press to flatten them into very thin patties.

Sear the patties without moving them for 2 to 3 minutes until a deeply browned, crispy crust forms on the bottom. Flip the patties over.

Immediately place a slice of cheddar cheese onto each of the flipped patties. Let them cook for another 1 minute until the cheese melts and the patties are cooked through.

In a separate pan, melt the remaining butter over medium heat. Fry the two eggs until the whites are set but the yolks remain runny.

Stack two cheesy meat patties on top of each other. Slide a sunny-side-up fried egg onto each double stack so the yolk acts as a rich, savory sauce. Serve immediately on paper plates for that authentic food truck experience.
