Ingredients & Their Flavor Purpose

For the Patty Melts:

1 lb ground beef – The star of the show. Provides juicy, meaty flavor with a perfect sear.
6 slices rye bread – Classic choice for a patty melt, offering robust flavor and crunch.
½ tsp onion powder & ½ tsp garlic powder – Season the beef with subtle, savory depth.
Salt and pepper, to taste – Essential for enhancing and balancing all other flavors.
6 slices cheddar cheese – Sharp and creamy, it melts beautifully for that classic cheeseburger vibe.
6 slices provolone cheese – Mellow and stretchy, it complements the cheddar and beef.
6 tbsp unsalted butter, softened – Coats the bread for a golden, crisp exterior.

For the Secret Sauce:

¼ cup mayonnaise – The rich, creamy base of the sauce.
2 tbsp chopped bacon pieces – Adds smoky crunch and savory umami.
3 tbsp ketchup – Sweet and tangy with a classic burger flavor.
1 tsp sugar – Balances acidity and enhances flavor.
1 tsp relish – Brings a zingy, pickle-forward brightness.

How to Make the Perfect Patty Melt with Secret Sauce

Step 1: Shape and Season the Patties

Form the ground beef into 3 thin, wide patties roughly the same shape as your bread slices.
Season both sides with onion powder, garlic powder, salt, and pepper.

Step 2: Cook the Patties

Heat a skillet over medium-high and cook the patties for about 3–4 minutes per side, until fully cooked through with a good crust.
Remove from skillet and set aside.

Step 3: Make the Secret Sauce

In a small bowl, combine mayonnaise, bacon, ketchup, sugar, and relish.
Mix until smooth and well blended. Refrigerate until ready to use.

Step 4: Assemble the Patty Melts

Wipe the skillet clean and reduce heat to medium.
Butter one side of each bread slice.
Place 3 slices, buttered side down, in the skillet.
On each slice, layer 2 slices of provolone, a beef patty, and 2 slices of cheddar.

Step 5: Finish & Toast

Spread secret sauce on the non-buttered side of the remaining bread slices.
Place them sauce-side down over each patty.
Grill until the bottom is golden and cheese begins to melt.
Carefully flip each sandwich and toast the other side until crisp and golden brown.

Pro Tips for the Ultimate Patty Melt

Shape patties thin and wide to avoid thick, burger-style bites—Patty Melts are meant to be flat and stacked.
Use a cast iron skillet for even heat and the perfect crust.
Don’t skip the double cheese combo—cheddar adds sharpness while provolone brings that ideal melt.
Let the sandwiches rest for 2 minutes after grilling to let the cheese settle and flavors meld.

Serving Suggestions

Pair your Patty Melts with:

Crispy seasoned fries or garlic Parmesan wedges
A simple arugula salad with vinaigrette for a fresh contrast
Pickles or coleslaw on the side for crunch and acidity
A cold craft beer or creamy milkshake to complete the retro diner vibe
