Classic Patty Melt Recipe

Try something different this week instead of your usual burger. A patty melt layers caramelized onions, swiss cheese and a perfectly thin burger patty on toasted bread. The caramelized onions make this patty melt. You’ll want to cook them slowly until the sugars breakdown. Add a splash of apple cider vinegar to help brighten the flavor. If you’d rather have an onion-free melt, use some vegetables like mushrooms or peppers instead.

Prep time: 10 mins
Cook time: 40 mins
Total time: 50 mins
Servings: 2 sandwiches


  • 1 sweet yellow onion, thinly sliced
  • 2 tablespoons butter, divided
  • 1 tablespoon apple cider vinegar
  • 8 ounces 90/10 ground beef
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 4 slices sandwich bread
  • 4 slices Swiss cheese
  • Mustard, optional


  1. Cook the onions: In a large cast-iron skillet 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.
    Near the end of cooking (about 5 minutes), add apple cider vinegar and stir to combine. Then remove from the skillet.
  2. Cook the patties: Shape 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.
  3. 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).
  4. Build your sandwiches in the skillet: On 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.
  5. Cook the sandwiches: Over medium-low heat, cook the sandwiches for 3-4 minutes per side until the bread is toasted and the cheese is melted.
  6. Serve: Slice sandwiches in half and serve immediately while warm.
