Description
A classic Patty Melt recipe combining juicy seasoned ground beef patties, melted Swiss cheese, and sweet caramelized onions between buttery toasted sourdough bread for a comforting and flavorful sandwich perfect for any meal.
Ingredients
Mayonnaise Mixture
- 4 tablespoons salted butter, softened
- 4 tablespoons mayonnaise
Beef Patties
- 1 pound 80/20 ground beef
- 2 teaspoons onion powder
- 2 teaspoons garlic powder
- 1½ teaspoons kosher salt, divided
- ½ teaspoon freshly cracked black pepper
- 2 teaspoons Worcestershire sauce
Sandwich Assembly
- 8 slices sourdough bread
- 8 slices Swiss cheese
- 1½ cups caramelized onions
Instructions
- Make mayonnaise mixture: In a small bowl, combine the softened salted butter and mayonnaise until smooth and well blended. Set aside.
- Make the patties: In a medium bowl, mix the ground beef with onion powder, garlic powder, 1 teaspoon of kosher salt, freshly cracked black pepper, and Worcestershire sauce until combined. Divide the mixture into 4 equal portions and shape each into thin patties roughly the shape of the bread slices. Sprinkle the patties with the remaining ½ teaspoon kosher salt.
- Cook the patties: Heat a skillet over medium heat. Cook the patties in batches if needed, about 3-4 minutes per side until they are cooked through and no longer pink in the middle. Transfer cooked patties to a plate.
- Spread the mayonnaise mixture: Spread one side of each sourdough bread slice with 1 tablespoon of the butter-mayonnaise mixture evenly.
- Assemble the sandwiches: Wipe out the skillet and return to medium-low heat. Place half the sourdough slices buttered side down. Top each with one slice of Swiss cheese, a cooked beef patty, and a generous amount of caramelized onions. Add another slice of Swiss cheese on top, and then cover with the remaining bread slices, buttered side up.
- Cook the sandwiches: Place the assembled sandwiches in the skillet. Cook about 4-5 minutes per side until the bread is golden brown and the cheese has melted, pressing gently with a spatula if desired. Cut each sandwich in half and serve immediately.
Notes
- Using 80/20 ground beef ensures juicy flavorful patties.
- Caramelized onions add sweetness; prepare them by slowly cooking sliced onions until golden brown before assembling.
- Use a medium or medium-low heat when toasting the sandwiches to avoid burning while melting the cheese thoroughly.
- Butter spread on the outside of the bread creates a rich, crispy crust.
- For extra flavor, Worcestershire sauce is added to the beef mixture.
