Ingredients for Blackstone Patty Melt Recipe
- Ground beef – We recommend using a lean ground beef so that the burgers aren’t too greasy. A ground chuck would also be tasty.
- Butter – Salted and unsalted butter will both work in this easy griddle patty melt recipe. Choose whichever you like best, or whatever you have on hand!
- White onion – White onion has the best flavor for patty melts. It isn’t too strong, and caramelizes really well.
- Beef seasoning – We’re pretty partial to our Gimme Some Grillin’ Beef Seasoning, so that’s what we’d recommend to give it great flavor. However, if you do not have that on hand you can use any of your favorite beef seasoning or sub in beef rub.
- Swiss cheese – That weird looking cheese with all the holes in it — it’s the secret ingredient to a perfect patty melt! If you don’t like Swiss cheese any type of cheese will work.
- Mayonnaise – Even if you’re not a fan of mayo, you should give it a shot in this recipe.
- Thick and hearty bread – It is important to use thick sliced bread so that the sandwich doesn’t fall apart and can withstand a little extra moisture.
How to Make a Blackstone Patty Melt
Preheat the Blackstone over medium-high heat. You can check it with an infrared thermometer, it should be about 450 degrees Fahrenheit.
Then, mix the ground beef and beef seasoning together in a large mixing bowl. Divide the beef into four even sized balls, about 4 ounces each.
Spread some mayo onto one side of each piece of bread.
Next, melt butter on one side of the flat top grill and then place the sliced onions on top. Sauté the onions in the butter for 3-5 minutes until they have caramelized, then move them to the side of the Blackstone.
Place the ground beef balls onto the griddle, where the onions were. Then put a piece of parchment paper on top of each beef patty and using a burger press, smash the meat into thin patties exactly like we do when we make smash burgers on the Blackstone.
Let the patties cook until they are browned and the edges are crispy. Then flip them over again and cook for 2-3 more minutes until brown. You’ll get the perfect tasty burgers.
Place 2 slices of Swiss cheese onto each patty to let it get all gooey and melted.
Next, place a slice of bread onto the Blackstone mayonnaise side down to toast it until it’s golden brown.
Once toasted, assemble each griddle patty melt with bread, a patty, ¼ of the sautéed onions, one tablespoon of mayo and the last piece of bread.
Cut in half and enjoy!
How to Store Leftover Blackstone Patty Melt
If you know in advance that you’ll have leftovers, don’t assemble extra patty melts. A burger will get soggy when stored after being assembled and cooked.
Place leftover toasted bread into an airtight container or plastic bag and store in the fridge for up to 2 days. Beef patties and onions should be stored in separate airtight containers. They will last for up to 4 days.
The cheese will last however long the package instructions say after opening.
What to Serve with Blackstone Patty Melt
After making a patty melt on Blackstone, you need some killer side dishes to go with it. You could go with a classic and make some french fries, or make something a bit more fancy and do some seasoned smoked potatoes.
Grilled foil packet potatoes are another delicious way to make potatoes and serve with this addictively good patty melt. Of course, you don’t have to do potatoes. Go with some veggies sides and make something like grilled sweet potatoes and grilled zucchini.
Smoked potato skins may typically be an appetizer, but they’re also a fabulous side dish. These Blackstone loaded smashed potatoes would be delicious too.
What bread is best for a patty melt?
A thick bread that isn’t too soft typically does best in a patty melt. Sourdough bread and rye bread are most popular and what you typically see used. However, a lot of people like using Texas toast too. My kids pick this because it looks like white bread and it’s easy to find at any local grocery store.! Really, you just need some thick sliced bread that will do well with hearty toppings inside.
Do I have to use swiss cheese?
Swiss cheese is most popular in patty melts, but certainly do not have to use it in this Blackstone patty melt recipe. Feel free to use any kind of cheese you want. Provolone is a great choice, as well as sharp or mild cheddar cheese, and even American cheese.
Pro Tips
- Don’t leave too much debris behind before toasting the bread. You want the Blackstone to still be greasy, but don’t leave chunks of onion or meat or they may leave a burnt taste on the toasted bread.
- If you do not have a burger press, just use parchment paper and a spatula to smash the burgers.
- Patty melts will cook more quickly than regular Blackstone burgers since they are smashed down. Make sure you watch them closely and don’t overcook!
The perfect patty melt in just twenty minutes time. An absolute star of a recipe that you are sure to enjoy!
