Ingredients You’ll Need

For the Patty Melt:

1 pound ground beef (80/20 blend recommended for flavor)
1 large yellow onion, thinly sliced
4 slices Swiss cheese (or American, if preferred)
4 slices rye bread (or any preferred sandwich bread)
2 tablespoons butter, for toasting the bread
Salt and pepper to taste

For the Secret Sauce:

¼ cup mayonnaise
2 tablespoons ketchup
1 tablespoon mustard
1 teaspoon Worcestershire sauce
½ teaspoon garlic powder
½ teaspoon onion powder
1 teaspoon pickle relish (optional for added tang)

How to Make the Ultimate Patty Melt

Step 1: Caramelize the Onions

Start by heating a skillet over medium heat and adding a drizzle of oil or butter. Add the thinly sliced onions to the pan and cook them slowly, stirring occasionally. The key here is patience – let the onions cook for about 15-20 minutes until they turn a deep golden brown and become sweet and tender. This process enhances the flavor profile of the sandwich.

Step 2: Prepare the Beef Patties

While the onions are caramelizing, shape your ground beef into 2 or 3 thin patties, depending on how thick you prefer them. Season both sides with salt and pepper. Cook the patties in a hot skillet until they’re nicely browned and cooked to your liking. You want the outside to have a good sear while the inside remains juicy.

Step 3: Make the Secret Sauce

In a small bowl, mix together all the secret sauce ingredients: mayonnaise, ketchup, mustard, Worcestershire sauce, garlic powder, onion powder, and pickle relish if you like an extra zing. This sauce adds a tangy, creamy element that ties everything together.

Step 4: Assemble the Sandwiches

Butter one side of each bread slice. On the unbuttered side, spread a generous layer of the secret sauce. Add a slice of cheese, then the cooked beef patty, caramelized onions, another slice of cheese, and finally, top with another slice of bread, buttered side up.

Step 5: Grill the Patty Melt

In the same skillet, grill each sandwich over medium heat until the bread turns golden brown and crispy, and the cheese is melted inside. Flip carefully to ensure even cooking on both sides, usually about 3-4 minutes per side. Serve immediately and enjoy the gooey, savory goodness!

Tips for the Best Patty Melt

Choose the Right Bread: Rye bread is a classic choice, but sourdough or white sandwich bread works well too.
Don’t Rush the Onions: Caramelizing onions takes time, but the flavor payoff is worth it.
Custom Cheese Choices: Swiss cheese offers a slightly nutty flavor, while American cheese melts beautifully for that classic diner-style melt.
Extra Crispy: For an extra crunch, try grilling the sandwich with a light coating of mayonnaise on the outside instead of butter.

Variations to Try

Spicy Patty Melt: Add some heat by mixing a little hot sauce into the secret sauce or topping the patty with pickled jalapeños.
Mushroom Patty Melt: Sauteed mushrooms make a great addition to the onions for even more umami flavor.
Bacon Patty Melt: Everything’s better with bacon! Add crispy bacon strips to your sandwich for an extra layer of indulgence.

What to Serve with Patty Melt

The Ultimate Patty Melt pairs wonderfully with classic sides such as:

French Fries: Go with crispy fries, sweet potato fries, or onion rings for a classic diner experience.
Coleslaw: The tanginess of coleslaw cuts through the richness of the sandwich.
Pickles: Dill pickles add a refreshing crunch to balance out the melt’s hearty flavors.

Storing and Reheating

If you have leftovers (though it’s hard to imagine with a sandwich this good), store the assembled patty melt in an airtight container in the fridge for up to 2 days. When reheating, it’s best to do so in a skillet to maintain the crispiness of the bread. Avoid microwaving as it will make the bread soggy.

Frequently Asked Questions

Can I make a patty melt with a different type of meat?

Absolutely! While ground beef is traditional, you can make a patty melt using turkey, chicken, or even plant-based patties for a vegetarian option.

What’s the best cheese for a patty melt?

Swiss and American cheese are the top choices due to their meltability, but you can experiment with cheddar, provolone, or pepper jack for a twist.

Can I prepare the onions ahead of time?

Yes, you can caramelize the onions a day in advance and store them in the fridge. Just reheat them before assembling the sandwiches.
