The Perfect Patty Melt

A patty melt is a delectable sandwich that combines the elements of a classic hamburger with the comforting goodness of a grilled cheese. This culinary delight typically features a seasoned beef patty, grilled onions, and melted cheese, all sandwiched between slices of toasted bread. Whether enjoyed in a diner or made at home, the patty melt is a satisfying treat that satisfies cravings for both a hearty burger and a grilled cheese sandwich.

What type of meat to use in patty melt

`The choice of meat for a patty melt is crucial in determining the sandwich’s flavor and juiciness. Typically, ground beef is the most popular choice. A blend of lean and fatty cuts, such as an 80/20 mix, is great to strike the right balance between juiciness and texture. Instead of smashing the patties in the pan while cooking, I pre smash them using a plate and some parchment paper. I used 120g of ground beef per patty which I believe is the perfect size for smash burgers.
