The Best Patty Melt Recipe

Making a homemade patty melt is about achieving perfection. A nostalgic sandwich like this is about reaching back into your memory banks to recreate that patty melt you always ordered at the diner near your grandparents house. A fast-food patty melt might let you down, but our patty melt recipe just might measure up. Caramelized Onions are the key, as is the homemade patty melt sauce. Sauce is the key to all great sandwiches, as proven by our perfect Burger Sauce, Thousand Island Dressing, and smoky Chipotle Mayonnaise.

How To Make A Patty Melt

  1. Make caramelized onions. You’ll need a good skillet and about an hour of time, but the best patty melt relies on a few really good ingredients, and you can’t skip the onions. You make them a day or two ahead of time and store them in the fridge, if need be.

  2. Season the beef, then form it into ¼ pound patties.

  3. Cook the patties! In large pan, until it’s cooked to your preferred level of doneness.

  4. Mix together the softened butter and mayo in a small bowl, and slather your bread with a that slightly wicked mixture.

  5. Build the patty melts. The order is as follows: slathered bread slice, Swiss cheese slice, beef patty, caramelized onions, second cheese slice, slathered, butter-side-up bread slice.

  6. Griddle your patty melts! Cook them over medium low heat—if your pan is too hot, the bread will burn before the cheese melts.

  7. Eat your patty melts!

How To Store + Tips For The Best Patty Melt

  • Leftover patty melts are not a thing. Well, maybe they are but we don’t recommend storing patty melts for long. They’ll be safe to eat for up to 3 days in the fridge, but patty melts are really meant to be eaten as soon as they’re cooked.

  • Swiss cheese is best and most classic kind of cheese to use on a patty melt. It’s worth a quick run to the store if you don’t have any on hand.

  • When mixing and forming the patties, use a gentle touch — don’t overwork the meat.

    About how many onions does it take to make 1 1/2 cups of caramelized onions?

    about 3 large onions. hope you enjoy! the "caramelized onions" in the ingredient list is a link if you want the recipe for the caramelized onions.

  • Abbi

    Does cooking the bread to melt the cheese also continue to cook the meat? Should I cook the patties a little more rare than usual? Thanks!

    No need, they will be fine. Hope you enjoy Abbi!

  • Jeffrey

  • CB

    Made it for my meal this evening and it was EXCELLENT! Unfortunately, I won't be able to eat it that often because of the high fat content, but it will become a favorite monthly meal. Thanks so much, because I'm a patty melt lover!

    Thanks CB, glad you loved it!

  • Chris

    These patty melts are perfect! Love this recipe. I have made several times. Thanks for posting .

    YAY! So glad you love them so much, thanks Chris!

  • Joan

    Was pretty good -- but I found the butter burned when grilling the sandwich at the very end, thus the bread also burned. I also made the meat patties way too thick.

    Glad you liked them Joan, you might want to turn the heat down a bit if the butter burned. Your stove might just run a little hot.

  • Monica

    Easy to follow and absolutely delicious! Will definitely make again.

    Thank you Monica! Happy to hear this! Thanks for trying it out.
