What’s a Patty Melt?
Imagine a cheesy, beefy, melty, and saucy sandwich topped with caramelized onions and a delicious sauce. Served between hearty bread slices, a classic Patty Melt is the best kind of sandwich. It’s ooey, it’s gooey, and it’s loaded with flavor.
And, made with affordable ground beef and your pick of cheese, it’s an inexpensive way to enjoy something delish. Layer caramelized onions, Swiss cheese, and a perfectly thin beef patty between toasted bread for the BEST patty melt ever!
More cheeseburger than sandwich? It is impossible to categorize. The legend in restaurants says that this beloved meaty, crispy, and melty sandwich was born sometime in the 1970s and was originally created in a restaurant in San Fernando.
It became incredibly popular among diners in most of the US. Some have described a hamburger melt as lovechild of hamburgers and a grilled cheese sandwich.
Blackstone Patty Melt Ingredients
- Bread – 2 slices (Rye bread, White bread, or your favorite)
- Ground beef, 2 smashed burger patties
- White Onion
- Swiss Cheese, Slices
- Patty Melt Sauce
How To Make a Patty Melt on Your Blackstone Griddle
Gather all your ingredients – this Patty Melt sandwich recipe cooks quickly once you start so you won’t have time to run around gathering ingredients. Preheat your Blackstone Griddle on medium heat. If using an Electric Blackstone Griddle, then set the dial to 400°F.
Slice the onion into thin strips. Melt the butter on the hot flat top. Add the sliced onions and cook until the onions are tender and golden brown.
While the onions are cooking, prepare the smash burgers. Place the hamburger balls onto the hot flat top griddle. Use a piece of parchment paper and a griddle spatula or burger press to smash the burger into thin patties.
Season the burger patties with your favorite seasoned salt and pepper. Let the patties cook until you have a crispy golden-brown outside layer.
Flip and cook the smashed burger patties until they are no longer pink inside. They should have a deep golden-brown color.
Top the beef patties with cheese, then butter and toast the bread. Add the cheese-topped patties to the toasted bread, top with the caramelized onions and the Patty Melt Secret Sauce. Serve immediately.
Patty Melt Sauce
Classic patty melt sauce is made with a few simple ingredients. Combine ¼ cup mayo, 2 tablespoons ketchup, 1 tablespoon of Dijon mustard, 1 teaspoon of pickle juice, ¼ teaspoon garlic powder and ¼ teaspoon paprika in a bowl until all ingredients are smooth.
Spread a dollop of the patty melt secret sauce onto the top piece of bread and place face down onto the burger and grilled onions.
Patty Melt Variations
The great thing about homemade Patty Melts is that you can jazz them up and change them any way you like! Here are some of my favorite variations:
- Use ground pork or turkey instead of beef to make the patties.
- Sauté some mushrooms and peppers with the onions for a fully loaded Patty Melt.
- Add some spice! Sauté some jalapeno’s with the onions.
- Switch up the cheese – Swiss is my favorite with Patty Melts, but you can use cheddar, pepper jack, blue cheese, a combination of several different cheeses, or whatever you like.
Tips for Making a Patty Melt
It is not just the caramel onion that makes the patty melt. The onions need to cook slowly for their caramelization so that they are brown and sweeter. It’s nice adding some cider vinegar to the onion to boost its sweetness.
The rich onion sweetness gives this patty a rich complex flavor. Without these you’d have cheeseburgers on toast, but onions give them a nice tangy flavor.
- You can use sweet onion or regular white or yellow onion.
- Swiss cheese is my pick for patty melts, but you can switch up the cheese. Get it pre-sliced from the deli to save you some time.
- Use good, thick bakery-fresh bread for this recipe. Inexpensive sandwich bread will fall apart. Try your Patty Melts with sourdough, crusty Italian, or rustic white bread.
- Watch your heat – onions will burn if the heat is too hot.
- Cook the patty melts in the buttery onions for even more flavor.
What To Serve with a Patty Melt?
Patty melts are pretty casual but make sure to have lots of napkins handy – so you’ll want to serve patty melts with equally casual side dishes.
I love a patty melt with a simple salad or a bowl of corn chowder soup, or you can go with more classic picks like Cheesy Tater Kegs or Sweet Potato Fries. Even a handful of crispy potato chips pair well with this easy Blackstone recipe.
How To Store Patty Melts
Once cooked and assembled, a Patty Melt won’t keep well because it’ll get the bread soggy. If you have leftovers, I suggest packaging the bread, onions, and beef separately.
The bread can stay on the counter for a day or two (provided it didn’t come in contact with the beef patties), and the remainder can be kept in an airtight container in the fridge for 3-4 days.
Frequently Asked Questions About Patty Melt Sandwiches
Leftover Patty Melts are so terrific and they’re easy to reheat. Toast the bread to warm it up a bit, then reheat the patty in a skillet or the microwave. Assemble your patty melt and enjoy!
Sure, Patty Melts can be keto or low carb if you skip the bread. Just omit the bread and grab a knife and fork and dig in, or wrap your patty melt in lettuce leaves.
No. Patty Melts are typically served on bread instead of a bun, and they don’t have the same toppings. Patty Melt Sauce is used in place of ketchup, relish, mustard, and other usual burger condiments.
There’s just something so delicious about cheesy, beefy goodness, and this greasy (but in a good way!) patty melt sandwich with onions and toasted bread is just an explosion of flavor.
Patty Melt Recipe
For the recipe and nutrition facts, click below.
- Bread, Thick Cut 2 slices
- Ground Beef 8 ounces
- Onion, Sweet White. 1/2 cup
- Butter 1 Tablespoon
- Swiss Cheese, Slices 2 each
- Preheat your Blackstone Griddle
- Slice the onion into thin strips.
- On a hot griddle, melt 1 tablespoon of the butter. Top the melted butter with the sliced onion. Caramelize the onion until a golden brown color is achieved.
- Cook the smashed burger patties by placing 2 - 4 ounce hamburger balls on the Blackstone Griddle. Put a piece of parchment paper on top of the burger ball and use your griddle spatula to smash the meat into very thin patties. Let the patties cook until they are crispy brown which will take about 2 - 3 minutes. Flip the patties over and cook the second side until crispy. Top with cheese before the burger is done so that you are not over cooking the patties.
- Butter the bread and toast on the flat top griddle.
- Stack the sandwich together starting with a piece of bread (toasted side down), add the cheese burger patties, top with the caramelized onions and add the patty melt secret sauce if desired. Finish the patty melt recipe sandwich with the top piece of bread making sure the toasted side is out.
- Serve hot with your favorite sides.
- I suggest you use sweet onion or you can use regular white or yellow onion.
- Swiss cheese is my preference for patty melts, but you can switch up the cheese. Make sure to get it pre-sliced from the deli to save you some time.
- Thick bakery-fresh bread works best for this recipe.
Cheap sandwich bread will fall apart. Try your Patty Melts with a good sourdough, crusty Italian, or rustic white bread.
- Watch your heat when cooking your onions. They will burn if the heat is too hot. You can also add a splash of apple cider vinegar to help with the caramelization process.
- Many Blackstone Griddlers like to cook their burger patty in the buttery onions for even more flavor.
- Patty Melt Sauce
This patty melt sauce is made with a few ingredients: combine ¼ cup mayo, 2 tablespoons ketchup, 1 tablespoon of Dijon mustard, 1 teaspoon of pickle juice, ¼ teaspoon garlic powder and ¼ teaspoon paprika in a bowl until all ingredients are smooth.
