Ingredients
For the Beef Patties
- Ground beef – 2 pounds
- Worcestershire sauce – 2 tablespoons
- Garlic powder – ½ teaspoon
- Salt & black pepper – to taste
For the Onions
- Extra-large sweet onion, thinly sliced – 1
- Butter – 4 tablespoons (for caramelizing)
For the Sandwich Assembly
- Thick-cut sandwich bread (Texas toast) – 12 slices
- American cheese – 6 slices
- Swiss cheese – 6 slices
- Yellow mustard – 2 tablespoons
- Butter – 4 tablespoons (for grilling bread)
Step-by-Step Instructions
Caramelizing the Onions
Start by caramelizing the onions, which will bring sweet, savory depth to the patty melt.
Melt 4 tablespoons of butter in a large skillet over medium heat. Add the thinly sliced onions and season with a generous pinch of salt and pepper.
Lower the heat to medium-low and allow the onions to slowly cook, stirring occasionally. After about 15 to 20 minutes, they should be golden brown, tender, and caramelized.
Once done, remove from heat and set aside.
Preparing the Burger Patties
In a large mixing bowl, combine the ground beef, Worcestershire sauce, garlic powder, and a pinch of salt and pepper.
Gently mix the ingredients by hand or with a fork until evenly combined. Do not overmix to avoid tough patties.
Divide the meat mixture into six equal portions and shape each into oval patties slightly larger than your bread slices. This ensures full coverage once cooked and assembled.
Cooking the Patties
Preheat a griddle or large skillet over medium heat.
Place the patties onto the hot surface and cook for about 3 minutes per side, or until they’re browned on the outside and just cooked through in the center. The patties will continue to cook slightly during the sandwich grilling stage.
Remove from the heat and set aside.
Assembling the Patty Melts
Begin building your patty melts while the patties are still warm.
Spread a thin layer of yellow mustard on one side of six bread slices. Top each with a cooked beef patty.
Add a generous spoonful of caramelized onions over each patty, followed by one slice of American cheese and one slice of Swiss cheese.
Top with the remaining bread slices to form six full sandwiches.
Grilling the Patty Melts
Wipe the griddle or skillet clean if needed. Melt 2 tablespoons of butter on the hot surface, then place the assembled sandwiches on top.
Cook over medium heat for 2–3 minutes per side, pressing gently with a spatula, until the bread is crispy and golden brown and the cheese is thoroughly melted.
If necessary, grill in batches, adding more butter between rounds to maintain a crisp, golden exterior.
Serving
Cut each patty melt in half diagonally and serve hot.
They’re great on their own or paired with classic diner sides like:
- Crispy fries
- Pickles
- Coleslaw
- Potato chips
- A dill pickle spear and soda pop
Flavor Profile
A patty melt is all about balance and texture:
- The juicy beef patty brings savory richness.
- The caramelized onions lend sweetness and depth.
- The two cheeses (American and Swiss) offer sharpness, creaminess, and that signature melt.
- The buttery, toasted bread provides crunch and a golden exterior.
Together, it’s a perfect blend of bold and cozy, crunchy and gooey, savory and sweet.
Tips for the Perfect Patty Melt
- Use thick bread: Texas toast or any thick-sliced bread holds up well during grilling and supports the heavy filling.
- Butter generously: Don’t skimp on the butter—it’s what gives that signature diner-style crispiness.
- Choose the right cheese: The mix of American cheese (for meltability) and Swiss (for nutty flavor) gives the best results.
- Caramelize low and slow: Resist turning up the heat on your onions. Low and slow brings out the deep, sweet flavor.
- Press lightly: Don’t smash your sandwich too hard while grilling, or the fillings might spill out.
- Customize the size: For smaller appetites, use regular sandwich bread and divide into 8 smaller melts.
Storage and Reheating
Refrigeration
Wrap leftovers tightly in foil or an airtight container. Store in the fridge for up to 2 days.
Reheating
Reheat patty melts in a skillet over medium heat to restore the crispy crust. Avoid the microwave—it makes the bread soggy.
Variations and Add-Ins
- Grilled onions and mushrooms: Add sautéed mushrooms for an umami boost.
- Spicy kick: Mix in chopped jalapeños or add spicy mustard to the sandwich.
- Different cheese options: Try pepper jack, provolone, or cheddar instead of Swiss.
- Rye bread: For a traditional twist, swap the Texas toast for light or marbled rye.
- Bacon strips: Add a couple slices of crisp bacon for extra indulgence.
- Patties from ground turkey: Use ground turkey with added olive oil and herbs for a leaner version.
FAQs
What’s the difference between a patty melt and a cheeseburger?
A patty melt is made on grilled bread (often Texas toast or rye) rather than a burger bun and usually includes caramelized onions and multiple cheeses. It’s grilled like a sandwich instead of flame-broiled like a burger.
Can I prepare the patties and onions ahead of time?
Yes! You can caramelize the onions and shape or cook the patties a day in advance. Store both in the refrigerator and reheat before assembling the sandwiches.
What bread works best for patty melts?
Texas toast is ideal for its thickness and sturdiness, but you can also use sourdough, rye, or hearty white sandwich bread.
Can I freeze patty melts?
You can freeze the cooked patties and onions separately, then assemble fresh. Freezing fully assembled melts isn’t recommended, as the bread may become soggy when thawed.
How can I prevent the bread from burning while the cheese melts?
Grill the sandwich on medium heat, not high, and cover the skillet briefly to trap heat and melt the cheese faster without burning the bread.
What can I serve with a patty melt?
Classic sides include French fries, onion rings, coleslaw, or pickles. For a lighter option, try a simple green salad or steamed veggies.
