Patty Melts with Secret Sauce

🥪 Patty Melt with Secret Sauce (Serves 2)

Ingredients

For the Patty Melts

  • 1 lb (450 g) ground beef (80/20 is ideal)

  • Salt & black pepper

  • 1 large onion, thinly sliced

  • 4 slices rye bread (marbled rye if you can find it)

  • 4 slices Swiss cheese

  • 2–3 tbsp butter (softened)

Secret Sauce

  • ¼ cup mayonnaise

  • 1 tbsp ketchup

  • 1 tbsp yellow mustard

  • 1 tbsp dill pickle relish (or finely chopped pickles)

  • ½ tsp garlic powder

  • ½ tsp onion powder

  • Pinch of smoked paprika (optional but 🔥)


🍳 Step-by-Step Instructions

1. Caramelize the Onions

  • Heat a skillet over medium-low heat.

  • Add a little butter or oil, then the onions.

  • Cook slowly, stirring occasionally, for 20–25 minutes until deep golden and jammy.

  • Set aside.

👉 Don’t rush this. Sweet onions = soul of the patty melt.


2. Make the Secret Sauce

  • Mix all sauce ingredients in a bowl.

  • Taste and adjust (more pickle = tangier, more ketchup = sweeter).

  • Chill if you have time—flavors get better after 10–15 minutes.


3. Form & Cook the Patties

  • Divide beef into 2 thin patties, slightly wider than the bread (they shrink).

  • Season both sides generously with salt and pepper.

  • Heat skillet to medium-high.

  • Cook patties about 3–4 minutes per side until browned.

  • Remove and rest.


4. Assemble the Sandwiches

For each sandwich:

  1. Butter one side of each bread slice.

  2. Inside-facing sides:

    • Spread secret sauce on both slices.

    • Add Swiss cheese → beef patty → caramelized onions → more Swiss.

  3. Close sandwich, buttered sides out.


5. Grill to Golden Perfection

  • Cook in skillet over medium-low heat.

  • Press gently with spatula.

  • Grill 3–4 minutes per side, until bread is crisp and cheese is fully melted.

  • Slice diagonally (mandatory, it tastes better).


🧠 Q & A (Real-Life Patty Melt Wisdom)

Q: Why rye bread instead of regular sandwich bread?

A: Rye has structure, flavor, and won’t collapse under grease and cheese. It’s part of the diner magic.


Q: Can I use a different cheese?

A: Yep.

  • Swiss = classic

  • American = ultra-melty

  • Cheddar = sharper flavor

  • Gruyère = fancy upgrade


Q: My sandwich burns before the cheese melts—help?

A: Heat is too high. Patty melts want low and slow at the end. You can also cover the pan briefly to trap heat.


Q: Can I make the sauce ahead of time?

A: Absolutely. It keeps 3–4 days in the fridge and actually tastes better the next day.


Q: What’s the best beef for patty melts?

A: 80/20 ground chuck. Lean beef dries out and kills the vibe.


Q: Can I make this on a griddle or cast iron?

A: Yes—and cast iron is actually ideal. Best crust, best melt.


Q: Any variations worth trying?

A: Oh yes:

  • Add sautéed mushrooms

  • Swap onions for grilled shallots

  • Add a dash of hot sauce to the secret sauce

  • Use sourdough if rye isn’t your thing
