The smash burger is the most honest burger there is. No fancy technique, no special equipment beyond a flat iron pan and a heavy spatula. You take a ball of 80/20 ground beef, press it hard onto a screaming hot surface, and cook it fast. The result is a burger with a deeply caramelised, lacey-edged patty that no thick-cut burger can match for flavour per bite. The fat you cook it in matters enormously. Tallow’s high smoke point gives you deep, even browning.
Why Tallow Makes the Best Smash Burgers
The Maillard reaction — the browning reaction between proteins and sugars that creates flavour — requires high heat and dry conditions. Tallow has a smoke point of approximately 420°F, significantly higher than butter at 300°F. This means the surface of the pan can be significantly hotter when you press the beef, producing a faster and deeper crust before the centre overcooks. The result is a burger that is crispy on the outside and still pink in the middle.
Serves 2 · Prep 10 min · Cook 8 min
Ingredients
- 400g 80/20 beef mince
- 2 tsp beef tallow
- Salt and black pepper
- 4 slices American cheese
- 4 brioche buns, toasted
- Yellow mustard
- Diced white onion
- Pickles
- Special sauce: 2 tbsp mayonnaise, 1 tbsp ketchup, 1 tsp pickle juice
- Lodge Cast Iron Skillet, 12 in: Heavy cast iron stays hot when the meat goes in, so it browns instead of steaming. Check price on Amazon
Method
- Divide beef into 4 equal balls (100g each). Do not season yet.
- Heat cast iron pan over highest heat for 3-4 minutes. Add tallow. The pan is ready when the tallow smokes immediately on contact.
- Place beef balls in the pan. Season the top with salt and pepper.
- Immediately press flat with a heavy spatula or burger press. Hold pressure for 10 seconds.
- Cook 90 seconds. Do not move the burger. The edges should be brown and lacey.
- Flip once. Add cheese immediately. Cook 60 more seconds.
- Stack two patties per bun. Serve with mustard, diced onion, pickles, and special sauce.
The Double Smash
The classic smash burger is always a double — two thin patties rather than one thick one. Two 100g patties gives more crust-to-meat ratio than a single 200g patty, and the cheese melts between the two layers creating a pull that a single-patty burger cannot achieve. Stack them tight.
Which fat for smash burgers?
| Fat | Flavour | Verdict |
|---|---|---|
| Beef tallow | Beefy, matches the patty | Best choice |
| Ghee | Nutty, buttery | Good alternative |
| Lard | Neutral, mild | Good, slightly weaker crust |
| Butter | Rich, dairy | For finishing only: the milk solids burn on a very hot pan |

Getting the crust: technique notes
- Use 20% fat mince. Leaner mince sticks and dries out; the fat is what fries the edges.
- Keep the balls cold and loose. Roll about 80 to 90g per patty and don't pack them tight. Keep them in the fridge until the pan is ready.
- Get the pan very hot. Cast iron or carbon steel, heated for several minutes, with a thin film of tallow.
- Smash once, early. Press hard within the first 10 to 15 seconds, using a square of baking paper between the spatula and the meat. Pressing later squeezes out juice instead of building crust.
- Leave it alone. Don't move the patty until the edges are deep brown and lacy, about 2 minutes. Season the top while you wait.
- Scrape, don't lift. Use a stiff, sharp-edged spatula to scrape under the crust, flip, add cheese and give it 30 to 60 seconds more.
Troubleshooting
- Sticks to the pan: the pan was not hot enough, or you flipped too soon. Scrape firmly with a metal spatula.
- Grey instead of brown: too many patties at once cools the pan. Cook two at a time.
- Falls apart: the mince was too lean or it was smashed after it had started to set.
- Lots of smoke: normal at this heat, but open a window and turn the extractor on. Tallow copes with the heat better than butter, whose milk solids burn.
What to serve with them

Frequently Asked Questions
Butter will work but has a lower smoke point, which means less browning. Use clarified butter (ghee) as the closest substitute for tallow's high-heat performance.
80/20 is the standard — 80% lean, 20% fat. Going leaner produces a drier burger. Going fattier can cause excessive flare-up and an oily result. 80/20 is the sweet spot.
Ideally yes. Cast iron retains heat better than stainless steel, which means when the cold beef hits the surface it does not drop the temperature significantly. A stainless steel griddle works as an alternative.
