The Patty Melt is a glorious diner classic that sits right at the intersection of a cheeseburger and a grilled cheese. It’s a masterpiece of simplicity and comfort food.
Here’s everything you need to know to make the perfect one at home.
The Core Concept
A patty melt is a sandwich consisting of a ground beef patty, sliced onions, and Swiss cheese, grilled between two slices of rye bread with butter.
Key Components & Why They Matter
-
The Bread: Rye (Marble Rye is ideal).
-
Why: The sturdy, slightly tangy flavor of rye stands up to the juicy beef and rich cheese without getting soggy. White or wheat bread doesn’t provide the same character. Marble rye (swirled light and dark) is the diner standard.
-
-
The Cheese: Swiss (or Gruyère).
-
Why: Swiss melts beautifully and has a nutty, sharp flavor that cuts through the richness of the beef and onions. American cheese is too mild and doesn’t belong here.
-
-
The Onions: Thinly Sliced Yellow Onions, caramelized.
-
Why: They are non-negotiable. Slowly cooked until sweet, golden, and soft, they are the “melt” in patty melt. Raw onions are too harsh.
-
-
The Patty: Thin, Seasoned Beef.
-
Shape: Form it slightly larger than your bread slice (it will shrink). Keep it thin—about 1/3 to 1/2 inch thick. Thick pub burgers don’t work here.
-
Seasoning: Salt and black pepper are essential. Sometimes a dash of Worcestershire sauce in the meat is a great boost.
-
-
The Cooking Fat: Butter.
-
Why: The bread is buttered on the outside and griddled until crisp and golden brown. This gives it that quintessential grilled cheese exterior.

Classic Patty Melt Recipe
Yield: 2 sandwiches
Prep/Cook Time: ~30 minutes
Ingredients
-
4 slices rye bread (marble rye preferred)
-
2/3 lb (300g) ground beef (80/20 lean/fat for flavor)
-
1 large yellow onion, thinly sliced
-
4-6 slices Swiss cheese
-
3 tbsp butter, divided
-
Salt and black pepper
-
Optional: Worcestershire sauce, mustard (yellow or Dijon)
Instructions
-
Caramelize the Onions: Melt 1 tbsp butter in a skillet or griddle over medium-low heat. Add onions, a pinch of salt, and cook slowly, stirring occasionally, for 20-25 minutes until soft, sweet, and golden brown. Transfer to a bowl.
-
Form the Patties: Divide beef into two equal portions. Gently form into oval shapes to match the rye bread. Season liberally with salt and pepper on both sides.
-
Cook the Patties: In the same skillet (increase heat to medium-high), cook patties for 2-3 minutes per side, until well-browned and cooked to your desired doneness (medium is typical). Remove and set aside.
-
Assemble the Sandwiches:
-
Spread a thin layer of mustard on the inside of each bread slice (optional but classic).
-
On one slice, place 1 slice of Swiss cheese, then the beef patty.
-
Top the patty with a generous heap of caramelized onions, then another slice of Swiss cheese.
-
Cap with the second slice of bread (mustard-side down).
-
-
Grill the Melts:
-
Wipe the skillet clean and return to medium-low heat.
-
Add 1 tbsp butter. Place assembled sandwiches in the skillet.
-
Cook for 3-4 minutes per side, pressing down gently with a spatula, until the bread is deeply golden brown and crisp, and the cheese is fully melted. Add the remaining butter when you flip.
-
-
Serve: Cut in half diagonally (the diner way!) and serve immediately.
Pro Tips & Common Variations
-
Don’t Rush the Onions: Low and slow is the key. If you’re short on time, at least cook them until very soft and translucent.
-
The Smash Variation: For extra crust, press the patty down firmly with a spatula when it first hits the hot pan (a “smash” technique).
-
The “California” Patty Melt: Adds thousand island dressing. (This is essentially a Reuben with a beef patty instead of corned beef).
-
The “Texas” Patty Melt: Uses sourdough bread and adds jalapeños.
-
Grilling: A cast-iron skillet or griddle is the best tool for the job.
What to Serve With It
-
Classic diner sides: French fries (shoestring or steak-cut), coleslaw, pickle spear, or a simple side salad.
