For the Patty:

  • 1 pound ground beef (80% lean)
  • Salt and pepper, to taste

For the Caramelized Onions:

  • 2 large onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon vegetable oil
  • Salt and sugar, to taste

For the Special Sauce:

  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon yellow mustard
  • 1 teaspoon white vinegar
  • 1 teaspoon sugar
  • 1/2 teaspoon paprika
  • Salt and pepper, to taste

Additional Ingredients:

  • Slices of American or Swiss cheese
  • Rye bread or Texas toast, sliced

For Assembly:

  • Butter for toasting
  • Pickles (optional, for serving)


Crafting the Perfect Patty:

  1. Forming the Patties: Divide the ground beef into portions and shape them into patties. Season generously with salt and pepper.
  2. Cooking the Patties: Grill or cook the patties in a skillet over medium-high heat until they reach your preferred level of doneness.

Caramelizing the Onions:

  1. Sautéing the Onions: In a skillet, melt butter and vegetable oil over medium heat. Add thinly sliced onions, a pinch of salt, and a hint of sugar. Sauté until the onions turn golden brown and caramelized.

Special Sauce Creation:

  1. Mixing the Ingredients: In a bowl, whisk together mayonnaise, ketchup, mustard, white vinegar, sugar, paprika, salt, and pepper until well combined. Adjust the seasoning to your taste.

Toasting the Bread:

  1. Buttering the Slices: Spread a thin layer of butter on one side of each slice of rye bread or Texas toast.
  2. Toasting to Perfection: Place the buttered side down in a skillet over medium heat until the bread becomes golden and crispy.

Assembling the Patty Melt:

  1. Layering the Goodness: On the non-buttered side of one slice of bread, place a cooked patty, a generous amount of caramelized onions, a slice of cheese, and a dollop of the special sauce. Top with another slice of bread, buttered side facing out.
  2. Grilling to Melty Perfection: Grill the assembled sandwich on both sides until the cheese is melted, and the bread is golden brown.


  1. Slicing and Plating: Cut the Patty Melt diagonally and serve it hot. Optionally, accompany it with pickles for a refreshing contrast.

Cook Notes:

  • Patty Thickness: Adjust the thickness of the patties based on your preference. Thicker patties may require a longer cooking time.
  • Onion Care: Keep an eye on the onions while caramelizing to prevent burning. Adjust heat and stir frequently for even caramelization.


Spicy Twist:

  • Infuse a kick of heat by adding a slice of pepper jack cheese or a dash of hot sauce to the special sauce.

Mushroom Medley:

  • Elevate your Patty Melt with sautéed mushrooms, adding a rich and earthy flavor to the classic recipe.

Keto Version:

Patty Transformation:

  • Opt for a higher lean-to-fat ratio in ground beef, such as 90% lean, to align with keto guidelines.
  • Replace rye bread or Texas toast with lettuce wraps for a low-carb alternative.

Onion Adjustment:

  • Caramelize onions with caution, using minimal sugar or omitting it entirely to reduce carb content.

Special Sauce Modification:

  • Use a sugar substitute in the special sauce, ensuring it complies with keto principles.

Low-Carb Version:

Bread Swap:

  • Substitute rye bread or Texas toast with low-carb bread options to reduce carbohydrate content.

Onion Moderation:

  • Limit the amount of caramelized onions or use a low-carb sweetener in the caramelization process.

Cheese Choices:

  • Opt for low-carb cheese options or adjust the quantity to align with reduced carbohydrate goals.
