What Is a Smash Burger?
I used to make dry, sad burgers too. Then I discovered the smash.
And honestly? It changed everything.
A smash burger isn’t just a thinner patty. It’s a whole different technique. Instead of forming a thick disk and hoping for the best, you take a ball of 80/20 ground beef, throw it on a screaming-hot surface, and smash it flat with all your strength. The result? A thin patty with crispy edges that are almost lacelike, a caramelized crust that’s deeply savory, and a juicy burger interior that stays tender. It’s the opposite of a grilled burger. It’s better.
These smash burgers are the kind you’d get at a diner. Or that trendy spot downtown. But you’re making them in your own kitchen, in about 25 minutes, with ingredients you can grab at Ralphs or Trader Joe’s. No fancy equipment required. Just a cast iron skillet or flat top griddle, a sturdy spatula, and a little bit of patience for that first side to get properly brown.
Why This Recipe Works
Look, I’ve tested a lot of smash burger recipes. Some are too complicated. Some use lean meat and end up dry. Some skip the secret sauce, which is honestly a crime. This one works because it’s built on three things that actually matter.
First, the meat. 80/20 ground beef is non-negotiable. That 20% fat is what renders out and creates those crispy edges. It’s what keeps the interior from tasting like a hockey puck. If you use 90/10, you’ll get a dry, sad patty. Don’t do it.
Second, the technique. You don’t just form a patty. You roll the meat into a ball, then smash it flat on the hot surface. This maximizes surface area. More surface area means more caramelized crust. More crust means more flavor. It’s simple physics, really.
Third, the sauce. This secret sauce is what takes these smash burgers from good to unforgettable. It’s tangy, creamy, and just a little bit sweet. It ties everything together. And it takes about 30 seconds to whisk together while your pan heats up.
Plus, this recipe is designed for a quick dinner on a busy weeknight meal. From start to finish, you’re looking at 25 minutes. That’s less time than it takes to order delivery and wait for it to show up.
Ingredients for Smash Burgers
Here’s what you need. Nothing weird, nothing hard to find. Just good, simple ingredients.
For the Burgers
- 12 oz ground beef (80/20) This is the sweet spot. Enough fat for flavor and crust, not so much that the patty falls apart.
- Salt Use kosher salt if you have it. But regular table salt works fine. Just season generously.
- Freshly cracked black pepper Don’t use pre-ground. It makes a difference. Trust me.
- 2 slices cheddar cheese Optional, but why would you skip it? American cheese is also classic. Use what you love.
- 2 brioche buns Split and toasted. The slight sweetness of brioche is perfect against the savory beef and tangy sauce. Potato rolls work great too.
- Dill pickle slices For serving. They add that essential crunch and acidity.
- Lettuce leaves For serving. Crisp and fresh.
- Tomato slices For serving. Use ripe ones if you can.
- Thinly sliced red onion For serving. Adds a little bite.
For the Secret Sauce
- 1/2 cup mayonnaise The base. Use full-fat for the best texture.
- 1/4 cup sour cream Adds tang and creaminess.
- 1-2 tablespoons ketchup For sweetness and color. Start with one, taste, add more if you like.
- 1 tablespoon yellow mustard That classic burger-joint flavor.
- Freshly cracked black pepper To taste. Just a pinch.
That’s it. No secret ingredients. No weird spices. Just good stuff.
How to Make Smash Burgers
Okay, let’s get into it. This is where the magic happens. I’ll walk you through each stage, and I’ll tell you exactly what to look for so you nail it on your first try.
Stage 1: Form the Patties
Start by dividing your 80/20 ground beef into 4 equal portions. Each one should be about 3 ounces. Roll each portion into a tight ball. Don’t overwork the meat just roll it gently between your palms until it holds together.
Here’s a trick I learned after my first attempt ended in a sticky mess: place each ball between two pieces of parchment paper. Then use the flat bottom of a small skillet to press it down. Press until it’s very thin, about 1/4-inch thick. The edges should be uneven and a little ragged. That’s exactly what you want. Those ragged edges will turn into crispy edges and lacy edge bits that are the best part.
Set the pressed patties aside on a plate, still between the parchment. Pop them in the fridge while you get the pan ready. Cold meat sears better.
Stage 2: Make the Sauce
While your pan heats up, make the secret sauce. In a small bowl, whisk together the mayonnaise, sour cream, ketchup, mustard, and a pinch of black pepper. That’s it. Taste it. Add a little more ketchup if you want it sweeter. Add more mustard if you want it tangier. This is your sauce make it yours.
Pop it in the fridge until you’re ready to use it. It’ll keep for up to a week, so you can make it ahead if you’re planning a quick dinner later in the week.
Stage 3: Cook the Patties
This is the most important part. Get your cast iron skillet or flat top griddle over medium-high heat. Let it heat up until it’s smoking hot. I mean really smoking. You see those wisps of smoke? That’s your signal. This is not the time to be shy with the heat.
Do NOT grease the pan. I know it sounds wrong, but trust me. You want the meat to stick a little. That sticking is what creates the crust.
Take one of your cold patties (still between the parchment). Peel off one side of the parchment. Season the exposed side with salt and pepper. Place it seasoned-side down onto the hot pan. Immediately peel off the other piece of parchment. Season the top side with salt and pepper.
Now, here’s the key: don’t touch it. Let it cook for 1 to 2 minutes. Listen for that sizzle. It should be loud and aggressive. If it’s not sizzling, your pan isn’t hot enough.
After 1 to 2 minutes, the edges will be browned and the bottom will be deeply crispy. You’ll see that caramelized crust forming. It should be a deep golden-brown. Use a thin metal spatula to get under the patty and scrape it loose. Flip it. Cook for another 30 seconds to 1 minute. During the last 30 seconds, top one patty with a slice of cheese. Stack the second patty on top of the cheese-topped patty. Remove the double patty from the pan.
Repeat with the remaining patties to make two double stacks.
Stage 4: Assemble the Burgers
While the pan is still hot, toast your brioche buns on the hot surface for about 30 seconds. Just until they’re lightly golden and warm. Don’t walk away they burn fast.
Now, assembly time. Spread a generous spoonful of the secret sauce on the bottom bun. Top with lettuce, a tomato slice, and some red onion. Place the double patty stack on top. Add a few dill pickle slices. Add more sauce on top of the pickles. Then the top bun.
Serve immediately. Like, right now. Don’t let it sit. The bun will get soggy, the cheese will firm up, and you’ll lose the magic.
Tips for the Crispiest Crust
Getting that perfect crust is the whole point of smash burgers. Here’s what I’ve learned from making these dozens of times.
My Top Tips
- Use 80/20 ground beef. I said it before, I’ll say it again. The fat is what creates the crust. Lean meat is for meatballs, not smash burgers.
- Get the pan screaming hot. If it’s not smoking, it’s not ready. You need that intense heat to create the Maillard reaction that gives you that deep brown crust.
- Don’t grease the pan. Counterintuitive, I know. But you want the meat to stick slightly. That sticking creates the crust. If you grease the pan, the meat slides around and you get a pale, sad patty.
- Smash thin. Really thin. Like, almost too thin. The thinner the patty, the more surface area contacts the pan, and the more crust you get.
- Don’t move the patty. Once it hits the pan, leave it alone. Let it cook for that full 1-2 minutes. Peeking too early will tear the crust.
- Use a thin metal spatula. A thick spatula won’t get under the crust. A thin, flexible one will slide right under and lift the patty cleanly.
Variations and Toppings
These smash burgers are perfect as written, but I’m not here to tell you what to do. Feel free to play around.
- Cheese swap: Cheddar is great, but American cheese gives you that classic diner melt. Swiss or Pepper Jack work too if you want something different.
- Bun swap: Brioche is my favorite, but potato rolls are a close second. They’re soft, slightly sweet, and hold up well.
- California twist: Add sliced Hass avocado. It’s not in the base recipe, but it’s a fantastic addition if you have ripe avocados.
- Onion smash: Try the Oklahoma onion burger style. Add a handful of thinly sliced onions on top of the patty right after you smash it. The onions cook into the meat and get crispy and sweet.
- Sauce variations: Add a little hot sauce to the secret sauce for a spicy kick. Or swap the yellow mustard for Dijon. Or add a pinch of smoked paprika.
- Toppings: Shredded lettuce instead of leaves gives better texture. Pickled jalapeños add heat. Crispy bacon is always welcome.
What to Serve with Smash Burgers
These smash burgers are pretty complete on their own, but a good side dish never hurt anyone.
- French fries Classic. Crispy, salty, perfect for dipping in extra secret sauce.
- Onion rings Beer-battered and golden. A great textural contrast.
- Coleslaw Tangy and crunchy. Cuts through the richness of the burger.
- Side salad Keep it simple with lettuce, tomato, and a light vinaigrette.
- Grilled corn on the cob Summer vibes. Brush with butter and sprinkle with salt.
- Sweet potato fries A slightly healthier option that still feels indulgent.
How to Store and Reheat Leftovers
Honestly, smash burgers are best eaten fresh. The crust is at its peak right off the pan. But if you have leftovers (unlikely, but possible), here’s how to handle them.
Storage: Store the patties and buns separately. Wrap the patties in foil and put them in an airtight container. Keep the buns in a bag at room temperature. Store toppings separately. The secret sauce keeps in the fridge for up to a week.
Reheating: The microwave will ruin the crust. Don’t do it. Instead, reheat the patties in a hot skillet over medium-high heat for about 30 seconds per side. This will restore some of the crispiness. Toast the buns again too.
Freezing: You can freeze the raw patties (between parchment) for up to 3 months. Cook them straight from frozen just add an extra minute to the first side. You can also freeze cooked patties, but the crust won’t be as good after thawing.

Notes

What kind of meat is used for Smashburgers?
Use 80/20 ground beef. That 20% fat content is crucial for creating the crispy edges and keeping the patty juicy. Leaner meat like 90/10 will result in a dry, less flavorful burger. Ground chuck works great too.
How do you smash burgers?
Roll the 80/20 ground beef into balls, place each between two pieces of parchment paper, and press flat with a heavy skillet or burger press until about 1/4-inch thick. Then cook on a screaming-hot cast iron skillet for 1-2 minutes per side.
Can I make smashburgers on the stovetop?
Absolutely. A cast iron skillet on the stovetop is perfect. Just make sure it’s smoking hot before you add the patties. Expect some smoke, so turn on your vent fan or open a window. A flat top griddle works even better if you have one.
Why does the beef need to be cold?
Cold beef sears better. When the meat hits the hot pan, the cold temperature helps create a more dramatic temperature difference, which leads to a better caramelized crust without overcooking the interior. Keep your patties in the fridge until you’re ready to cook.
What’s the best meat for smash burgers?
80/20 ground beef is the gold standard. The fat renders out and creates those crispy edges and that deep, beefy flavor. Ground chuck (also 80/20) is a great substitute. Avoid anything leaner than 85/15.
I don’t have a griddle what can I use?
A cast iron skillet is your best bet. It gets hot and stays hot, which is exactly what you need for a good crust. A stainless steel pan works too, but avoid nonstick pans they prevent the sticking that creates the crust.
