🍔 Smash Burger
Adaptable for: 🌾 Gluten-Free 🥑 Keto 🥛 Dairy-Free 🍃 Paleo
A smash burger is all about the crust. Smashing a loose ball of beef onto a screaming-hot surface maximizes contact, and that contact is where the deeply browned, crispy-edged magic happens.
The smash burger looks like a trick and is actually the easiest great burger to make at home — if you understand what the smash is for. It is not about making the patty thin for the sake of it; it is about forcing the maximum amount of beef against the maximum amount of hot metal to trigger the Maillard reaction. That browning is the entire point, so everything in this method protects the crust.

From I Love Hamburger — ilovehamburger.com
Ingredients
- 1 lb (450g) ground beef, 80/20 chuck
- 4 slices American cheese
- 4 soft potato buns
- Kosher salt and black pepper
- Neutral oil, for the griddle
- Optional: thinly sliced onion to smash into the patty
- Burger sauce, to serve
Instructions
- Do NOT season or pack the beef. Roll it into 4 loose balls (about 4 oz each, or 8 balls at 2 oz for doubles). Keep them loose — packing kills the crust.
- Heat a flat griddle or cast iron over high until it is rippling hot. A drop of water should evaporate on contact. Add a thin film of oil.
- Place a ball on the surface. If using onions, put a pinch on top first. Lay a piece of parchment over it and smash HARD and flat with a press for a full 10 seconds, until it is about 1/4" thick.
- Remove the parchment and now season the top with salt and pepper. Do not move the patty — let it cook undisturbed for about 2 minutes until the edges are brown and lacy.
- Scrape under it with a stiff, thin spatula to keep all the browned crust attached, then flip.
- Immediately add cheese. Cook just 45–60 seconds more — the thin patty cooks fast. Ground beef should reach 160°F (71°C).
- Toast the buns on the griddle in the rendered fat. Build with sauce, stack the patty (or two), and serve right away.
👨🍳 Tips for the best Smash Burger
- A flat, heavy press beats a spatula. You want even, full-contact pressure for the first 10 seconds only.
- Smash within the first 30 seconds of the beef hitting the heat — once it starts to cook it won't spread thin.
- Use parchment between the press and the beef so it doesn't stick and tear the crust.
- Two thin patties (a double) give more crust than one thick one — that's the smash-burger move.
🥗 Make it fit your diet
This smash burger adapts easily. Here's how to make it work for common specialty diets:
🌾 Gluten-Free
Use a certified gluten-free bun or wrap it in crisp lettuce. Double-check sauces and seasoning blends — soy sauce, some Worcestershire, and pre-mixed rubs can hide gluten.
🥑 Keto / Low-Carb
Go bun-less or lettuce-wrapped (a.k.a. protein-style), skip ketchup and BBQ sauce or use no-sugar-added versions, and pile on cheese, bacon, and avocado.
🥛 Dairy-Free
Skip the cheese or use a dairy-free alternative, cook in oil instead of butter, and stick to dairy-free sauces (most mayo, ketchup, and mustard are fine).
🍃 Paleo / Whole30
Wrap it in lettuce (no bun), skip the cheese, and use compliant sauces with no added sugar, soy, or dairy. For Whole30, make sure any bacon is sugar-free.

Frequently asked questions
Why aren't my smash burgers crispy?
Almost always one of three things: the surface wasn't hot enough, you packed the beef too tightly, or you moved the patty too soon. Read our Smash Burger Mistakes to Avoid guide.
Do you smash burgers on a grill?
Not directly on the grates — the beef falls through and you lose the crust. Put a cast iron pan or griddle plate on the grill and smash on that.
What beef is best for smash burgers?
80/20 ground chuck. The fat renders against the hot surface and crisps the edges. Don't use lean beef for smash burgers.
