Smash burgers stand out for their thin patties, deeply browned crust, and crispy edges while staying juicy inside. Getting that signature texture comes down to a few details, from choosing the right beef to smashing it against a very hot, flat cooking surface.
This guide covers how to make smash burgers at home, including the basic technique and methods for a Blackstone, stovetop, or outdoor grill.
1. What Makes a Good Smash Burger?
A good smash burger is all about contrast: a thin patty with a deeply browned crust and crispy edges, while the inside stays juicy. Unlike a thick burger, the beef is pressed firmly onto the cooking surface at the beginning of cooking to maximize contact with the heat.
That direct contact encourages the Maillard reaction, the browning process that creates the savory flavor and dark crust associated with smash burgers. A very hot, flat surface such as a cast iron skillet or griddle gives the beef more contact than standard grill grates, helping that crust develop quickly.
2. What You Need to Make Smash Burgers
Before learning how to make smash burgers, gather everything first because the actual cooking happens quickly.
Ingredients:
- Ground beef: 80/20 beef is a good choice because the higher fat content helps keep thin patties juicy.
- Salt and pepper: Keep the seasoning simple so the browned beef remains the focus.
- Cheese: American cheese melts particularly well, but cheddar or another melting cheese also works.
- Burger buns: Soft buns such as potato or brioche buns work well with thin patties.
- Toppings and sauce: Pickles, onions, lettuce, burger sauce, mustard, or your preferred toppings.
Equipment:
- Heavy spatula or burger press: You need firm, even pressure to smash the beef.
- Parchment paper: Place a small sheet between the beef and press to prevent sticking.
- Flat cooking surface: A cast iron skillet, flat-top griddle, or Blackstone provides the direct surface contact needed for a strong crust.
3. How to Make Smash Burgers: 6 Easy Steps
The key to how to make smash burgers at home is to work quickly and avoid handling the beef more than necessary. Have the toppings and buns ready before the patties hit the hot surface.
Step 1. Divide the Beef Into Loose Balls
Divide the ground beef into loosely packed balls, roughly 2-3 ounces each for thin patties. Avoid squeezing or compacting the meat as you shape it.
Keep the beef refrigerated until shortly before cooking. Loose balls are easier to flatten and help create the irregular, crispy edges characteristic of smash burgers.
Step 2. Preheat the Cooking Surface
Heat a cast iron skillet or griddle over medium-high to high heat until it is very hot. The beef should begin sizzling immediately when it touches the surface.
A properly preheated surface is important because rapid browning helps form the crust before the interior overcooks.
Step 3. Smash the Patties Thin
Place a beef ball on the hot surface, cover it with a small piece of parchment paper, and immediately press it firmly with a heavy spatula or burger press.
Smash the patty until it is very thin, around ¼ inch thick or thinner. Apply the pressure at the beginning rather than repeatedly pressing the burger as it cooks.
Step 4. Season and Let a Crust Develop
Season the exposed side with salt and pepper, then leave the patty alone.
Cook for roughly 1½-2 minutes, or until the bottom develops a dark brown crust and the edges look browned and crisp. Avoid moving the patty around while the crust is forming.
Step 5. Scrape, Flip, and Add Cheese
Slide a firm metal spatula underneath the patty and scrape firmly against the cooking surface so the browned crust stays attached to the beef.
Flip the patty once, immediately add cheese, and cook the second side briefly until the beef is cooked through and the cheese melts.
Step 6. Toast the Buns and Assemble
Toast the cut sides of the buns on the hot cooking surface until lightly golden.
Add your sauce and toppings, then place one or two patties on each bun. Serve immediately while the edges are still crisp and the cheese is hot.
4. How to Cook Smash Burgers on Different Surfaces
The basic smash technique stays the same, but the cooking setup changes depending on what you have available. The most important requirement is a very hot, flat surface that gives the beef enough direct contact to develop its signature crust.
On a Blackstone Griddle
For how to make smash burgers on Blackstone, preheat the griddle over medium-high to high heat and lightly oil the surface if needed. Place the beef balls on the hot griddle, smash them immediately, and cook without moving them until a dark crust forms.
A Blackstone works especially well because its large, flat surface provides plenty of room for multiple patties while maintaining direct contact with the beef.
On the Stove
If you’re learning how to make smash burgers on stove, a heavy cast iron skillet is one of the best options. Preheat the skillet until very hot, then cook only as many patties as comfortably fit without crowding.
Smash each beef ball immediately after it hits the skillet. Because indoor cooking can create plenty of smoke and splatter, use your kitchen ventilation and keep the surrounding area clear.
On an Outdoor Grill
For how to make smash burgers on the grill, avoid smashing the beef directly onto standard grill grates. The gaps prevent full surface contact and make it difficult to create the characteristic crust.
Instead, place a flat griddle, plancha, or cast iron skillet over the grill grates and allow it to preheat thoroughly. Then smash and cook the patties on that flat surface just as you would on a stovetop or Blackstone.

5. Common Smash Burger Mistakes to Avoid
Once you understand how to make smash burgers, avoiding a few common mistakes can make the difference between a crisp, juicy burger and a dry or poorly browned one:
- Using beef that’s too lean: Some fat helps thin patties stay juicy and flavorful. An 80/20 blend is a reliable choice.
- Packing the beef too tightly: Keep the beef balls loose rather than forming dense patties beforehand.
- Starting with a cool cooking surface: Without enough heat, the beef can steam instead of developing a deep crust.
- Smashing too late: Press the beef immediately after it hits the surface, before the patty has started cooking through.
- Pressing repeatedly: Smash once at the beginning rather than continuing to press the patty and squeeze out juices.
- Moving the patty too soon: Give the first side enough uninterrupted contact with the surface to brown properly.
- Flipping without scraping: Scrape firmly underneath the patty so the browned crust comes off the cooking surface with the burger.
- Overcooking the second side: Thin patties cook quickly, so they generally need much less time after flipping.
Conclusion
Learning how to make smash burgers comes down to three essentials: loosely packed beef, a very hot flat surface, and a firm smash at the start of cooking. Give the first side time to develop a deep crust, flip only once, and serve immediately for crispy edges and a juicy center.
