This patty melt turns a regular sandwich into something unforgettable thanks to a special sauce. Toasty rye bread, gooey cheese, sweet caramelized onions, and juicy beef come together to hit the spot every time. That tangy secret sauce brings extra zip, balancing out all the rich flavors so nothing feels too heavy.
I came up with these patty melts one chilly night when our family needed a real pick-me-up. The smell of onions caramelizing pulled everyone into the kitchen. Now, whenever someone needs cheering up, this sandwiches always gets requested—sometimes more than once a month.
Tasty Ingredients
- Dijon mustard gives a fancy tang, making everything taste brighter
- Rye bread stands out and pairs perfectly with the beef
- 85/15 ground beef keeps things juicy but not greasy
- Cheddar and Swiss cheeses melt together for the best cheesy pull
- Caramelized onions, thinly sliced, get super sweet and juicy—take your time when cooking them
- Worcestershire sauce brings unbeatable savory depth to the patties
- Mayonnaise is the creamy base that holds the special sauce together
Simple How-To
- Assemble and Toast Your Sandwich
- Spread butter on one side of each bread slice. Lay a piece down in the pan, butter side down, and start stacking: cheddar, beef patty, onions, a generous helping of your special sauce, then Swiss. Place the second bread slice on top, buttered side up. Cook on medium until the outside is golden and crispy and cheese is fully melty, flipping carefully so all the good stuff stays inside.
- Shape and Fry the Patties
- Mix ground beef with salt, pepper, and Worcestershire sauce just until everything's combined—don't mash too much. Flatten into thin patties that fit the bread. Cook each one in a hot pan for 3-4 minutes per side until both sides are nicely browned and cooked through.
- Sauté Your Onions
- Pour a bit of olive oil into a pan and gently cook the onions over medium-low heat. Let them cook slowly, stirring every so often, until they're soft, super sweet, and deep golden—about half an hour. If they start sticking, splash in a little water and turn down the heat.
- Mix Your Secret Sauce
- Dump mayonnaise, ketchup, Dijon, pickle juice, paprika, and garlic powder into a bowl. Stir until you've got a creamy, blended sauce. Make this before anything else so the flavors have a chance to come together (the pickle juice pops out and cuts the richness nicely).

My favorite thing? Adding Worcestershire to the meat. It actually has anchovies, which is why the patties taste so rich and savory. My grandma always kept a bottle of it handy—said it made any beef dinner shine. This sandwich is proof she was right.
Awesome Caramelized Onions
If you want those patty melts to truly stand out, take your time with the onions. Don't rush things. Let them slowly cook on medium-low for at least 30 minutes. The longer they go, the sweeter and more jammy they'll get. You'll know they're done when they're a deep gold and taste almost like onion candy—worth every second of waiting.
Prep Ahead Tips
This dish is great for prepping ahead or making for company. Whip up the sauce and onions days in advance, and you can even shape the patties the night before and stash in the fridge. Everything keeps fine in airtight containers. When it's time, just fry the patties and build your sandwiches—super simple yet seriously impressive.
Tasty Pairings
These melts shine on their own, but pairing with sides really rounds things out. Fries or kettle chips are classic, but if you're looking to lighten things up, go for a crisp salad with vinaigrette. During colder weather, a bowl of homemade tomato soup is unbeatable—the tangy soup balances all that cheesy richness and beefy goodness perfectly.
