Smash burgers are proof that the best meals don't need to be complicated. Some grass-fed and finished ground beef, a hot skillet, and a little salt and pepper — that's all it takes to get a thin, crispy-edged, flavourful burger that rivals anything from a restaurant. If you've never made one at home, you're in for something special.
Why Smashing Works
The idea of pressing a burger flat on the grill used to be thought of as a mistake. Conventional wisdom held that if you did that it would squeeze out all the juices. But with smash burgers, the opposite is true.
When you press cold ground beef onto a very hot surface, you maximize the contact between the meat and the heat. That triggers something called the Maillard reaction — a chemical process where amino acids and sugars in the beef react at high temperatures to create hundreds of flavour compounds and that irresistible, deeply browned crust. The thinner the patty, the more surface area gets that treatment, and the more flavour you get in every bite.
And because you're smashing the beef while it's still cold — before the fat has a chance to render — the juices stay locked in. The result is a patty that's crispy and caramelized on the outside and juicy on the inside.
It also helps to start with ground beef that has a good fat content. That fat is where much of the flavour lives, and it's what gives a smash burger its richness as it caramelizes on the hot surface.
How to Make Them at Home
You don't need any special equipment. A heavy skillet — cast iron or stainless steel — and a sturdy metal spatula are all it takes.
Start by portioning your ground beef into loose balls, roughly 115 to 140 grams (4 to 5 oz) each. Don't overwork the meat or pack it tightly. Keeping it loosely formed helps the patty stay tender. Season the outside of each ball with salt and pepper, and keep them cold until you're ready to cook.
Heat your skillet over high heat — ideally to around 200 to 230°C (400 to 450°F). If you don't have a way to check, a drop of water should sizzle and evaporate almost immediately. Place a ball of beef on the skillet and immediately press it down as flat as you can with your spatula, holding firm for about 10 to 15 seconds. If the meat sticks to the spatula, placing a small piece of parchment paper between the two does the trick. You're aiming for a patty that's about 6 mm (¼ inch) thick with edges that spread out and get crisp.
Don't touch the patty once it's down. Let it sear undisturbed for about 2 minutes. You'll see the colour creeping up the sides as the crust develops underneath. When the edges are browned and the top is starting to turn from pink to grey, use your spatula to scrape the patty up from the skillet — make sure you get all of that beautiful crust — and flip.
If you're adding cheese, lay a slice on as soon after you flip the burger. The residual heat melts it perfectly. Cook for another minute or so, and you're done.
A Few More Tips
Toast your buns. Butter the cut side and press them face-down in the skillet for a minute until golden. It adds flavour and keeps the bun from getting soggy under all those juices.
Try a double stack. Many smash burger fans swear by two thinner patties with cheese melted between them — more crust, more flavour, and the cheese stays perfectly good in the middle.
Keep your toppings simple. Classic choices like pickles, mustard, relish, and sliced onion all work beautifully. If you want to go bold, try aged cheddar, blue cheese, or jalapeños.
Honestly though, when you start with quality beef, you don't need much else. Our grass-fed and finished ground beef has the fat content and flavour to make smash burgers your whole family will want more of.
