How to Make Skillet Sourdough Patty Melt with Special Sauce
STEP ONE: Prepare the Special Sauce
In a small bowl, mix together ¼ cup mayonnaise, 1 tablespoon ketchup, 1 teaspoon Dijon mustard, 1 teaspoon pickle relish (optional), ¼ teaspoon smoked paprika, and ¼ teaspoon garlic powder. Set aside.
STEP TWO: Caramelize the Onions
In a skillet, heat 1 tablespoon olive oil over medium heat. Add the sliced onion and cook until soft and caramelized, about 8-10 minutes. Remove from the skillet and set aside.
STEP THREE: Cook the Patties
Mix the ground beef with 1 teaspoon Worcestershire sauce, salt, pepper, and seasoning. Form the ground beef into 4 equal-sized patties.
In the same skillet, add 1 tablespoon olive oil. Cook the patties over medium-high heat until browned and cooked through, about 4-5 minutes per side. Remove from the skillet and set aside.
STEP FOUR: Assemble and Grill the Patty Melts
Spread butter on one side of each slice of sourdough bread. On the unbuttered side of 4 slices, spread a thin layer of the special sauce. Place a cooked patty on top of the sauce, add a slice of cheese, caramelized onions, a few raw jalapeno slices (optional), another slice of cheese, and top with another slice of bread, butter side out.
In the same skillet, melt a bit more butter over medium heat. Grill the assembled sandwiches until the bread is golden brown and crispy, and the cheese is melted, about 3-4 minutes per side.
How Should I Store and Reheat this Recipe?

Recipe FAQs
A patty melt differs from a cheeseburger in its bread choice and preparation. While a cheeseburger typically uses a hamburger bun, a patty melt is made with slices of bread, often rye, and is grilled like a sandwich. Patty melts usually include caramelized onions and a special sauce for a distinct flavor.
Yes, you can make a patty melt without a skillet. An alternative method is to use a griddle or a grill pan. If you don't have these, you can use a regular frying pan or even cook the patties and assemble the sandwich in an oven or toaster oven.
To make a patty melt healthier, consider using lean ground beef or ground turkey instead of regular ground beef. Opt for whole grain or gluten-free bread instead of traditional sourdough or rye. You can also reduce the amount of cheese or choose a lower-fat cheese.
