Classic Patty Melt

The Classic Patty Melt…
When a grilled cheese meets a hamburger.
The Bread should be sliced rye (seeded or seedless, depending on preference) is traditional and provides a subtle tang that balances the richness of the other ingredients. Some might opt for sourdough or even Texas toast, but classic rye offers a unique and essential flavor profile.
The Beef patty should be made from freshly ground chuck, ideally an 80/20 lean-to-fat ratio. This ensures juiciness and flavor. They should be seasoned simply with salt and pepper, cooked on a hot griddle or cast-iron skillet to develop a beautiful sear and crust, while remaining juicy on the inside.
The Onions should be deeply caramelized. This is where the magic truly happens.
The Cheese must be melty and flavorful. The classic choice for a patty melt is Swiss cheese. I prefer a sharp cheddar. And then there are those people that like American cheese… Well, they are not invited to this party!
The Classic Patty Melt is stacked with meat, onions and cheese and then cooked until golden brown and crispy, and the cheese is fully melted and oozy.

  • Prep: 15 mins
  • Cook: 40 mins
  • Yields: 4 Servings

Ingredients

2 onions, thinly sliced

4 tablespoons butter, divided


1 pound 80/20 ground beef

salt and pepper, to taste


8 slices rye or sourdough bread


8 slices Swiss or Cheddar cheese


mustard, optional

Directions

Cook the onions

1In a large cast-iron skillet or griddle set over medium to medium heat, add 1 tablespoon of butter and sliced onions. Cook onions, stirring occasionally, for about 25 minutes until they are a deep brown color. If the onions are burning on spots, you might need to turn your heat down to medium-low.

2Near the end of cooking (about 5 minutes), add apple cider vinegar and stir to combine. Then remove from the skillet.

Cook the patties


1Shape ground beef into two thin 4-ounce patties that are roughly the shape of your bread. Season patties with salt and pepper. 
When onions are done in your skillet, set the heat to medium-high and add the patties. Cook for 3 minutes per side. If your patties are thin, that should be enough time to cook them through. Remove patties when done. 
Butter your bread 
Wipe your skillet clean and add the last tablespoon of butter to the skillet. Once the butter melts, add all the bread slices to the skillet, so one side of each slice is coated with butter. Remove two of the four pieces of bread and start building your sandwich on the two pieces remaining in the skillet (you can also do this one at a time depending on the size of your skillet). 


Build your sandwiches 


1On each slice of bread remaining in the skillet, add a slice of Swiss cheese, a patty, half of the caramelized onions, and top with the second slice of Swiss cheese. Top each sandwich with the slice of bread removed from the skillet earlier, buttered side up.


Grill the sandwiches

1
Over medium-low heat, cook the sandwiches for 3 to 4 minutes per side until the bread is toasted and the cheese is melted. 
Slice sandwiches in half and serve immediately while warm.
