What is a Blackstone Smash Burger?

A Blackstone smash burger is a small burger ball that is smashed thin and cooked on a flat-top griddle until both sides are crispy.

Top with your favorite burger toppings and pair with a butter toasted mini pretzel bun or regular burger buns. The smash burger flavors are endless!!!!!

How Do You Make a Blackstone Smash Burger?

Learning how to smash your burger on a Blackstone Flat Top takes a little bit of practice. This is where many cooks fall short.

Some use a smash Blackstone burger kit; others use a burger press. You need to find the style that works for you!!

I like to just use one griddle spatula along with a piece of parchment paper to make my smash burgers. The trick is the parchment paper in-between the burger patty and the smashing tool!

How Hot Should Griddle Be for Smash Burgers?

The temperature of your Blackstone Flat Top is very important. If the griddle is not hot enough, you will not get a good crispy beef patty.

If the temperature is too hot, the beef patties will become over cooked and loose it’s great flavor. I like to set my griddle to medium heat.

If you would like a griddle temperature, it should be around 375°F. All burgers cook differently! This Blackstone griddle smash burgers tips and tricks will help you create the best burgers.

How to Make an Onion Swiss Pretzel Bun Burger

Preheat the Blackstone Griddle Grill on medium heat. Gather your ingredients to make your pretzel bun burger.

You want to use ground beef that has a little bit of fat in it. I like to use 80/20 ground beef (80% lean).

Gently form your burger balls. That’s right, burger balls, not burger patties! Start your fried onion burgers by lightly oiling the griddle.

Place your onions onto the hot oil. Let the onions caramelize as they cook and only toss occasionally.

Onion Burger – Two Ways!

First Way: Place the burger balls onto the hot flat top grill making sure to space them out. Have the onions on the side, cooking separately with a little bit of olive oil.

A pile of cooked onions on a flat top griddle along with a couple of round smash burger balls.

Smash the burger balls on the flat top (as described below). Let the burger cook on both sides. Assemble your swiss and grilled onion burger in layers.

Second Way: After the sliced onions have been cooking on the griddle for several minutes (with a little bit of olive oil), place the burger ball on top of the cooking onions. Smash the burger ball over top of the onions so that the ground meat and onions start cooking all together.

When the burger is ready to flip, take the spatula under the whole pile and flip both the patty and onions at the same time. Cook the second side of the patty until done. Top with the swiss cheese and assemble your burger in layers.

Try both cooking methods because they will taste completely different. You will have to let me know which one is your favorite!! I would love to know which one everyone likes best.

Smashing Burgers

Smashing burgers on a Flat Top griddle takes practice. Use the back of your griddle spatula with a piece of parchment paper on top of the burger ball.

Flatten the burger balls in a quick swift motion getting them very thin. Don’t forget, a thin patty is what you want!

Some gridlers use 1 or 2 spatulas to smash the burger patty. You might like to use a Blackstone burger press (hamburger press).

All works, but the smashing burgers trick is to use wax or parchment paper in between the burger and the tool used to smash the patties.

Once the beef burger patty is smashed, carefully peel the paper off starting on one side and working your way to the other side until the paper is completely separated from the beef patty.

Season your mini grilled onion burger with your favorite seasoning such as salt and pepper. My family likes to use Lawry’s Seasoned Salt and Morton’s Natures Seasons.

Remember that the SMASHING burger patties should be thin and fry up crispy. Let the burgers cook and do not fuss with them.

Meanwhile, on a separate part of the griddle. Lightly butter the inside of the pretzel buns, place on the flat top, and toast while everything is cooking.

You will not believe how much better these taste with toasted pretzel buns! If using older pretzel buns, using melted butter to create buttered buns will revive your bread.

How Long to Cook Smash Burgers on a Griddle?

Smash patties fry up quickly! Two to three minutes on each side if the Blackstone flat top is hot.

Cook the first patty side until golden and crispy, then flip to cook the second side until desired doneness is achieved. Place a slice of swiss cheese on top and let melt.

Air temperature and wind will play a role in how long it takes to cook the patties. You want a golden-brown crispy outside with a juicy inside.

Don’t overcook the patties causing them to dry out. Overcooked patties do not taste very well!

Onion and Swiss Burgers Assembly

Once the onions and burger patties are cooked, it’s time to assemble your pretzel bun burger. I made onion swiss sliders with mini pretzel burger buns.

Start with the griddle toasted bottom pretzel bun topped with a layer of crisp lettuce. Next, top with the melted swiss cheese smash burger.

If making a double stack onion and swiss burger, add a second swiss cheese patty. Top with the sautéed griddle onions and all your favorite toppings and condiments.

Finally, place the toasted top pretzel bun to the Blackstone burger stack and serve while hot.

Pretzel Bun Burger on Blackstone – FAQ

Pretzel Buns – Where to buy?

You have several options when buying pretzel burger buns. Try your local bakery. If you don’t see any then ask. They might have insight on if they will make some or where to get them.
