🔥 Step-by-Step Cooking Instructions

1️⃣ Make the Secret Sauce

In a small bowl, combine mayonnaise, ketchup, relish, and Worcestershire sauce. Stir until smooth and set aside.

2️⃣ Caramelize the Onions

Melt 1 tbsp butter in a skillet over medium heat. Add the sliced onions and cook, stirring occasionally, until they become golden and caramelized (about 15–20 minutes). Set aside.

3️⃣ Cook the Beef Patties

Divide the ground beef into 4 equal portions and shape into thin patties slightly larger than your bread (since they shrink when cooked). Season with salt and pepper.

Cook patties in the same skillet over medium-high heat for about 3–4 minutes per side until they’re cooked through. Remove from the skillet.

4️⃣ Assemble the Patty Melts

• Butter one side of each slice of rye bread.

• On the non-buttered side of 4 slices, layer Swiss cheese, a beef patty, caramelized onions, cheddar cheese, and top with another slice of bread (butter side up).

5️⃣ Grill the Sandwiches

Heat a clean skillet or griddle over medium heat. Cook each sandwich for 2–3 minutes per side until the bread is golden brown and the cheese is melted.

6️⃣ Serve with Secret Sauce

Slice each patty melt in half and serve hot with a side of the secret sauce for dipping or drizzling.

💡 Tips for the Best Patty Melt

✔ Use sturdy bread. Rye is traditional, but sourdough or Texas toast also work well. Avoid soft sandwich bread as it can become soggy​

.

✔ Don’t skip the caramelized onions! Cooking them low and slow brings out their natural sweetness, enhancing the flavors of the sandwich​

.

✔ Season your beef properly. Salt and pepper right before cooking to lock in flavor​

.

✔ Cook on medium-low heat. This prevents the bread from burning before the cheese has melted​

.

✔ Customize the cheese. Swiss and cheddar are classics, but pepper jack or American cheese can add a unique twist​

.

✔ Press down lightly. Use a spatula to gently press the sandwich while grilling for even toasting and melting​
