Patty Melt Ingredients
Classic patty melts are a delightful comfort food that everyone needs to try!
For the Caramelized Onions
- Unsalted Butter Adds richness and helps in cooking the onions to perfect sweetness; can substitute with olive oil for a lighter option.
- Onions Choose yellow onions for the best flavor and sweetness; sweet or red onions can also provide lovely alternatives.
For the Patty
- Ground Beef (at least 20% fat) The main protein, offering juiciness and flavor; turkey or plant-based meats can be used for healthier or vegetarian options.
- Kosher Salt & Black Pepper Essential for seasoning and bringing out the flavors in both the beef and onions.
For the Sandwich
- Seeded Rye Bread This provides a unique texture and flavor; pumpernickel or whole wheat bread can also work in a pinch.
- Swiss Cheese Melts beautifully to create that gooey texture; try cheddar or provolone for a fun twist.
How to Make Patty Melts
Caramelize Onions: In a skillet over high heat, melt 2 tablespoons of unsalted butter. Add the sliced onions, sprinkle with kosher salt, and cook without stirring for 1 minute. Stir for 5 minutes until translucent, then reduce the heat and cook for 30-40 minutes until golden brown and sweetly fragrant.
Prepare Burger Patties: In the same skillet, add the remaining butter. Form the ground beef into four patties, seasoning them with salt and black pepper. Cook for 2-2.5 minutes on high heat without moving them. Flip and cook until rare, then let them rest to retain juices.
Assemble Sandwiches: In the skillet, toast 4 slices of rye bread in the beef fat for extra flavor. Layer with a slice of Swiss cheese, add a beef patty, top with the caramelized onions, place another slice of cheese, and finally crown with another slice of rye. Press down gently and flip to brown both sides until the cheese is oozy and the bread is golden brown.
Serve: Slice the sandwiches in half to reveal the glorious fillings and serve warm.
Optional: Pair with crispy fries or a tangy pickle for the ultimate diner experience.

Tips for the Best Patty Melts
Perfectly Caramelized Onions: Keep the heat low and stir occasionally after the initial cooking. This ensures they become sweet and tender without burning, enhancing the flavor of your patty melts.
Flavorful Seasoning: Don’t skip on salt and pepper! Season both the onions and patties generously to elevate the dish. Remember, seasoning is key to a well-balanced flavor.
Don t Overwork Meat: Handle the ground beef gently when forming patties. Overworking can lead to a tough texture, making your patty melts less enjoyable.
Hot Skillet Magic: Preheat your skillet properly to ensure that both the patties and bread brown perfectly. A hot surface helps to lock in juices while creating that delicious crispy crust we all love.
Cheese Melting Tip: Layer cheese on both sides of the patty for maximum gooeyness. This creates a delightful experience that you won’t be able to resist!

If you’re accommodating specific diets, consider using ground turkey or plant-based meat alternatives for a healthier or vegetarian option.

The more the merrier when it comes to fulfilling everyone s cravings!

To reheat your frozen patty melts, start by removing them from the freezer and letting them thaw overnight in the refrigerator.

This method will keep all the flavors intact and the bread just as delightful as when they were freshly made.
