Classic Smashed Burgers Recipe (2024)

Why It Works

  • Smashing down on the burger patties within the first 30 seconds of hitting a hot skillet ensures maximum juiciness and a flavorful, well-browned crust.
  • Using a well-heated, heavy-bottomed skillet helps the crust brown evenly.
  • A firm, flat metal spatula helps to get every last bit of crust off of the skillet.

"Never ever press down on your burger!"

Classic Smashed Burgers Recipe (1)

How many times have you read that in a book or heard a TV chef say it?"It squeezes the juices out!" "It turns your lunch into a hockey puck!" Sometimes they'll try and appeal to your compassionate side."Certainly there are some things that deserve crushing. Evil grapes. T-800 model Terminators. Rebel scum trapped in trash disposals. But what has that poor, defenseless little burger ever done to you to deserve such a fate?"

You've heard it so many times you can'thelpbut believe it's true, right?

Well okay, Mr. Smarty-Chef, I'll believe you, but first, you must answer me these questions three:

  • Question the first:One of my favorite burgers in New York—the one that folks'll stand in line for an hour to get—is smashed. How does theShake Shack burger still retain such abundant juiciness?
  • Question the second:TheSmashBurger chain of fast-casual burger joints has built its reputation on its smashing technique. Are all of its fans (which are legion) deluded into enjoying the flavor of dry hockey pucks?
  • Question the third:I just had what was the finest burger I've tasted in recent memory atOff-Site Kitchenin Dallas where—guess what?—the burgers are smashed. What gives?

Now, these questions are largely rhetorical, and anybody who's been making burgers for a while or has been reading Serious Eatsfor long enough knows the answer: not smashing your burgers isalways,sometimes, only sort of occasionally, good advice.

When is it okay to smash your burgers and when is it not? Well first, let's consider theadvantagesof smashing a burger.

A Good Crust Creates Deep Flavor

Classic Smashed Burgers Recipe (2)

There's really only one reason to do it, and it's the reason that all three of the burgers I mentioned above (as well as countless others) taste so good:The Maillard reaction. The Maillard reaction—also known as the browning reaction*—is a series of chemical reactions that take place when protein-rich foods are heated. Large proteins break into smaller compounds, which react with others and recombine into new configurations. They break apart again, recombine, and on and on in a cascade of chemical reactions that create hundreds of brand new compounds.

*This is not to be confused with caramelization, which is a reaction that takes place when sugar is heated. You can't caramelize a steak or a burger, no matter what any TV chef tells you!

It's what creates the crust on your steak or burger, the golden brown color on your toast, and the complex, pleasing aromas and flavors that accompany that browning. It's the smell of a steakhouse and fresh bread from the oven.And it's the smell of a good burger joint.It doesn't just make meat taste good, it actually makes ittaste more meaty.

Most of the browning reactions don't take place until foods are heated to at least 300°F (150°C) or so, and are greatly accelerated at temperatures higher than that, so if maximizing browning is your goal when cooking a burger (and it should be!), then it's plain to see why smashing a burger can improve its flavor:It maximizes contact with the pan, which means it increases the surface area directly in contact with the hot metal and therefore maximizes browning.

While it's true that given enough time you can brown even a non-smashed burger, there are a couple of problems. If the heat is too high, the browning will be uneven—at worst, the bits of meat directly in contact with the skillet or griddle will burn before the bits elevated above it can even begin to brown properly. With lower heat, you can get more even browning, but it takes longer—long enough that your burger will end up overcooking in the middle (and overcooking is therealpath to dry burgers).

Smashing allows you to get a deep brown crust before the interior overcooks, even with a relatively small patty.

Proper Smashed Burgers Are All About Timing

Classic Smashed Burgers Recipe (3)

So when is itnota good idea to smash? Well, there's the obvious:you can't smash a burger on a grill.

But what about in a skillet or griddle? I cooked through a couple dozen burgers smashing at various stages during cooking in order to make sure. The results?If you don't want to lose juices, you must smash within the first 30 seconds of cooking.

When ground beef is cold, its fat is still solid and its juices are still held firmly in place inside small, chopped up segments of muscle fibers. That's the reason why you can push and press on ground meat without squeezing out too much liquid, and the reason why you can smash a burger during the initial phases of cooking without fear of losing moisture.

But what happens after that initial cooking phase as the meat warms up?

When you look at a burger under a microscope, you basically see what amounts to an interconnected network of proteins interspersed with fat and water-based liquids. Like all meats, as a burger cooks, this protein network tightens, squeezing out liquids. Simultaneously, the fat begins to render and liquefy, allowing it to be squeezed out right along with the other juices.

In a properly formed burger—one that is made with meat that's been ground properly, kept chilled, and minimally handled while shaping—the protein matrix is relatively loose. Even once fat has been liquefied and the protein network tightens, juices can remain trapped in the patty, only getting released when you bite into the burger, in much the same way that liquids can be trapped in a sponge and only released by squeezing.

Press down on a burger duringthisphase, and the juices come gushing out into the skillet or onto your coals. You're left with what amounts to a meat patty with the texture of a sponge that's been run through a ringer.

All burgers will lose weight as you cook them—it's not possible to hold on to all liquefied fat and exuded juices. In my testing, four-ounce burgers that started as round pucks and were smashed down to a half-inch thickness any time before 30 seconds still lost a little over 20% of their weight while cooking. This was comparable to four-ounce burgers that were formed into 1/2-inch disks and cooked with no smashing at all. Both burgers tasted quite juicy, while the smashed burger had better flavor (obviously!).

Once you start smashing after the 1 minute mark, juicesreallystart to flow and you end up with a dramatically drier burger—a good 50% more moisture is lost in a burger smashed after 1 minute versus one smashed within 30 seconds.

Move into the territory ofdouble- or even triple-smashing—that is, smashing once at the beginning, then getting impatient and smashing again and again during the middle and latter phases of cooking—and a burger can easily lose half of its weight to the evil griddle gods. I've seen more than one short order cook at a greasy spoon with a backup of orders resort to this dastardly method, and not once have I ever taken more than one bite of a burger that's been exposed to it.

If you've read my breakdown of theFake Shackburger, you already know the best way to cook a smashed burger at home. But I realized that I've never produced a more generic recipe for a classic smashed burger, so here you go.

Three Rules for Smashed Burger Success

Other than the basic rules of burgers (use meat with at least 20% fat; make it with a goodblend of cutsor straight ground chuck, preferablyfreshly ground; and don'tadd salt or other seasoningsuntil after the patties are formed), making a smashed burger is simple. Just follow these basic rules:

Rule 1: Use a good stainless steel, carbon steel, or cast iron skillet.

Classic Smashed Burgers Recipe (6)

The goal is steady, even heat, so you want to use a relatively thick pan and allow it to preheat for long enough that there are no hot or cool spots. I let my pans preheat over medium heat for a few minutes, pumping them up to high just before I add the meat. Don't use a non-stick pan, as the high heat required for a good crust is damaging to non-stick coatings and can cause the coatings to vaporize. You don't want to breathe that junk in.

Rule 2: Smash early and smash firmly.

Classic Smashed Burgers Recipe (7)

I have a thick, flat,sturdy metal spatulaspecially devoted to the task of smashing burgers. You'll need one to do this properly. Form four to five ounces of meat into a puck about 2 inches high, season liberally with salt and pepper, and place it on the preheated skillet, then smash down on it with the spatula, using a second spatula to add pressure if necessary. Then just cook without moving until a deep brown crust develops. This'll take about a minute and a half.

Rule 3: Leave no crust behind.

The whole goal of smashing is to develop a nice, deeply browned crust, so it's important that you scrape it all up intact. Once again, a sturdy metal spatula is your friend. I find that flipping the spatula upside down to help scrape the crust off is pretty effective. If your crust is properly developed and your burger properly smashed, it should spend very little time on its second side—just enough to finish cooking through and to allow cheese to melt (if added), about 30 seconds or so.

Prep5 mins

Cook10 mins

Active6 mins

Total15 mins

Serves4 burgers


  • 1/2 teaspoon vegetable oil

  • 16 to 20 ounces (455g to 570g) ground beef, divided into four 4-ounce portions (see notes)

  • Kosher salt and freshly ground black pepper

  • Cheese slices (if desired)

  • Four toasted burger buns

  • Toppings and condiments, as desired


  1. Add oil to a 12-inch stainless steel, carbon steel, or cast iron skillet and wipe around with a paper towel. Set skillet over medium heat and allow to preheat for about 5 minutes. Meanwhile, gently form each portion of ground beef into a cylindrical puck about 2 inches tall, pressing together just until meat holds its shape without falling apart. Season generously on all sides with salt and pepper.

  2. Increase heat under skillet to high and heat until skillet is smoking. Add 2 beef pucks to skillet and, using a firm, stiff metal spatula, press down on each one until they're roughly 4 to 4 1/2 inches in diameter and 1/2-inch thick. It helps to use a second spatula to apply downward pressure to the first if you are having trouble smashing them hard enough.

  3. Cook without moving until a golden brown crust develops, about 1 1/2 minutes. Use the edge of the spatula to carefully scrape up and flip the patties one at a time, making sure to get all browned bits removed from the skillet. If using cheese, add now.

  4. Continue to cook until patties are cooked to desired doneness—about 30 seconds longer for medium-rare. Transfer patties to toasted buns, topping buns and/or patties as desired, close burgers, and serve immediately. Wipe out skillet with paper towel and repeat process with remaining ground beef pucks.

Special Equipment

Heavy-bottomed stainless steel, carbon steel, or cast iron skillet; large, firm metal spatula


For best results, ask your butcher to freshly grind beef for you, or do it yourself at home. You can use straight ground chuck, or for better flavor, use a blend of short rib, brisket, and chuck or oxtail meat. Proper care of your meat grinder is critical if you choose to grind at home. You can read our review of the best meat grinders right here.

We recommend cooking only two patties at a time in a 12-inch skillet. Patties can also be cooked one at a time using a smaller skillet.
