Ingredients for The Best Patty Melt

This recipe is divided into three components: the sandwich, the secret sauce, and the caramelized onions.

For the Patty Melt

• 1 lb ground beef (80/20 for the juiciest burgers)
• Salt and pepper, to taste
• 4 slices rye bread
• 2 tbsp unsalted butter (for toasting the bread)
• 1/2 cup shredded Swiss cheese
• 1/2 cup shredded American cheese
• 1/2 cup caramelized onions (prepared below)

For the Secret Sauce

• 1/4 cup mayonnaise
• 1 tbsp Dijon mustard
• 1 tbsp ketchup
• 1 tbsp pickle relish
• 1 tsp Worcestershire sauce
• 1/2 tsp smoked paprika
• Salt and pepper, to taste

For the Caramelized Onions

• 1 large onion, thinly sliced
• 1 tbsp olive oil
• 1/4 tsp sugar
• Salt and pepper, to taste

Preparation Method

Follow these step-by-step instructions carefully to achieve the perfect patty melt.

Prepare the Caramelized Onions

Heat olive oil in a skillet over medium heat.

Add the thinly sliced onions and cook, stirring occasionally, until they begin to soften. This usually takes about 5 minutes.

Add sugar, salt, and pepper, then continue cooking for 10 to 15 minutes, stirring frequently.

The onions should become golden brown, soft, and sweet. Once done, remove from heat and set aside.

Make the Secret Sauce

In a small bowl, combine mayonnaise, Dijon mustard, ketchup, pickle relish, Worcestershire sauce, smoked paprika, salt, and pepper.

Mix thoroughly until smooth and creamy. Taste and adjust seasoning if needed.

Set aside until ready to assemble the sandwiches.

Prepare the Beef Patties

Divide the ground beef into 4 equal portions and shape into thin patties slightly larger than the bread slices.

Season both sides generously with salt and black pepper.

Heat a skillet or grill pan over medium-high heat.

Cook the patties for about 4 to 5 minutes per side, depending on your preferred doneness.

Once cooked, remove from heat and set aside.

Assemble the Patty Melts

Butter one side of each slice of rye bread.

Place two slices on a clean surface, buttered side down.

Spread a generous layer of secret sauce on the unbuttered side.

Add a cooked beef patty on top of each slice.

Layer with a mix of Swiss and American cheese, followed by a portion of caramelized onions.

Top with the remaining bread slices, buttered side facing outward.

Toast the Sandwiches

Heat a large skillet or griddle over medium heat.

Place the assembled sandwiches in the skillet.

Cook for 3 to 4 minutes per side, pressing lightly with a spatula.

The bread should become golden brown and crispy, while the cheese melts completely.

Flip carefully to ensure even toasting on both sides.

Serve Hot

Remove the patty melts from the skillet and let them rest briefly.

Slice in half and serve immediately while warm and melty.
