Ingredients

1 lb ground beef
8 slices of rye bread
8 slices of Swiss cheese
1 large onion, thinly sliced
4 tbsp butter, plus more for spreading on bread
Salt and pepper to taste
1/2 cup mayonnaise
2 tbsp ketchup
1 tbsp relish
1 tsp Worcestershire sauce
1/2 tsp garlic powder
1/2 tsp onion powder

Step-by-Step

Start by caramelizing the onions. In a large skillet over medium heat, melt 2 tablespoons of butter. Add the sliced onions and a pinch of salt. Cook, stirring frequently, until the onions are soft, jammy, and golden brown, about 15-20 minutes. Remove the onions from the skillet and set aside.
While onions cook, mix together the ground beef with a little salt and pepper. Shape the beef into 4 thin, wide patties (they should be roughly the size of your bread slices).
In a small bowl, stir together the mayonnaise, ketchup, relish, Worcestershire sauce, garlic powder, and onion powder to make your secret sauce. Set aside.
In the same skillet (wipe clean if needed), melt another tablespoon of butter over medium-high heat. Sear the beef patties for 3-4 minutes per side, until well-browned and cooked through. Remove from skillet and set aside.
Assemble the patty melts: Lay out 4 slices of rye bread. Spread a layer of secret sauce on one side of each slice. Top each with a slice of Swiss cheese, a beef patty, a scoop of caramelized onions, another slice of cheese, and finally, another slice of bread. Spread the outsides of each sandwich with a thin layer of butter.
Working in batches (as needed), place the sandwiches in the skillet over medium heat. Press gently with a spatula and cook 3-4 minutes per side, until the bread is golden brown and the cheese is completely melted.
Remove from heat, slice diagonally, and serve hot with extra secret sauce for dipping.

What to Serve Ultimate Patty Melt with Secret Sauce With

Nothing beats a cozy meal that’s well-rounded and satisfying! Serve your patty melt with a crisp dill pickle spear for that classic diner touch. Pair it with homemade French fries or sweet potato fries for crunch, or go lighter with a fresh green salad or tangy coleslaw. Creamy tomato soup is another comforting choice, perfect for dunking those cheesy corners. For a drink, ice-cold lemonade, root beer, or a simple iced tea completes the nostalgic feel. Dessert? Why not finish with a warm cookie or a scoop of vanilla ice cream?

Top Tips for Perfecting

For extra flavor, swap Swiss cheese for sharp cheddar or provolone.
Don’t rush caramelizing the onions—low and slow is key for deep, sweet flavor!
Make sure beef patties are thin and even, slightly larger than the bread—they’ll shrink as they cook.
Rye bread is classic, but sourdough or Texas toast make tasty alternatives.
Ensure the skillet isn’t too hot; cook over medium to prevent burning before cheese melts.
Butter the bread, not the pan, for even browning and crunch.
Add a sprinkle of pepper or hot sauce to the secret sauce if you like a bit of kick.

Storing and Reheating Tips

Patty melts are best enjoyed fresh, but leftovers can be just as tasty! Store any cooled sandwiches in an airtight container or wrap tightly in foil. Refrigerate for up to 3 days. To reheat, pop a sandwich in a nonstick skillet over medium-low heat, pressing gently until warmed through and crispy again—about 4-5 minutes per side. Alternatively, reheat in a toaster oven for extra crunch. Avoid microwaving, as the bread may become soggy. To freeze, wrap uncut, cooked patty melts in foil, then in a freezer bag—freeze up to 1 month. Thaw in the fridge overnight before reheating as above.

FAQs

How can I make the patty melt healthier?
Use lean ground beef or swap in ground turkey for a lighter option. Try low-fat cheese and mayonnaise in the sauce, and use whole grain rye bread.

Can I prepare the onions or sauce ahead of time?
Absolutely! Caramelized onions and secret sauce can be made a day or two in advance and kept in the fridge. Making ahead speeds up assembly on busy nights.

What if I don’t have rye bread?
Sourdough, whole wheat, or even regular sandwich bread will all work in a pinch. The flavor will change slightly, but you’ll still have a delicious result.

Is there a vegetarian version?
Yes! Substitute the beef patties with a plant-based burger option or even a thick-cut portobello mushroom. Keep the same assembly, and you’ve got a vegetarian-friendly patty melt.

Can I add more toppings?
Definitely. Feel free to add sautéed mushrooms, roasted red peppers, sliced pickles, or pepper jack cheese for a spicy kick. This recipe is super versatile!
