The Smash Burger Starter Kit: 5 Tools for Crispy, Diner-Style Burgers at Home

As an Amazon Associate, PlanetBurger earns from qualifying purchases. How we choose the gear we recommend.

To make diner-style smash burgers at home, you need a heavy flat cooking surface, a stiff scraping spatula, and a way to smash the beef hard and evenly. A smash press, an instant-read thermometer and a cheese melting dome make the job easier and more consistent. If you're starting from scratch, a cast iron skillet, a heavy-duty spatula and a thermometer cover the essentials.

Quick picks

• Best overall surface: Made In Carbon Steel Griddle. A large flat-top with room to cook a full batch.
• Best budget pan: a Lodge cast iron skillet. A great crust, two patties at a time.
• Most overlooked tool: Firsgrill Heavy-Duty Griddle Spatula. Scrapes up the crust instead of leaving it on the pan.

What makes a great smash burger

Every tool in this kit supports one of three jobs:

1. A ripping-hot, flat surface that stays hot when cold beef lands on it.
2. One hard smash early, within roughly the first 30 seconds, while the beef is still cold.
3. Getting every bit of crust off the pan when you flip.

You can make good smash burgers with any heavy pan and a sturdy spatula. The rest of the kit is about doing it faster, more evenly and with less guesswork. If you're new to the style, start with Smash Burger vs. Regular Burger.

1. A flat, heavy cooking surface

The crust forms where beef meets hot metal, so the pan matters more than anything else. Thin pans lose heat the moment cold meat hits them, and the beef steams instead of browning. Look for:

• Thick cast iron or carbon steel that holds heat.
• A flat, rimless or low-sided surface so your spatula can get under patties at a low angle.
• Enough room for the batch size you usually cook.

Our top pick is the Made In Carbon Steel Griddle, a flat-top for the stove or the grill with room for several patties at once. Learn more on our flat-top griddle page.

On a budget? A cast iron skillet builds an excellent crust; you'll just cook two or three patties at a time.

2. A stiff, sharp spatula

The best part of the crust sticks to the pan. A rigid spatula with a sharp front edge scrapes under the patty and brings that crust with it. A flexible fish spatula or a plastic turner won't. This is the tool most home cooks are missing, and it can also smash in a pinch if you push down on it with a second spatula.

Look for a blade that doesn't flex, a straight sharp edge and a handle that keeps your hand clear of the heat. Our pick is the Firsgrill Heavy-Duty Griddle Spatula from the quick picks above.

3. A smash press

A press gives you even, thin patties with one firm push. A flat base means consistent thickness, and a vertical handle lets you put your weight behind it. Lay a square of parchment between the beef and the press so nothing sticks.

It's the most optional tool in the kit, but it's worth it if you cook smash burgers often or for a crowd. See our smash burger press pick, or compare the two approaches in smash burger press vs. spatula.

4. An instant-read thermometer

Thin smash patties cook in just a few minutes, but the USDA still recommends 160°F for ground beef. Checking by color isn't reliable, so a fast instant-read thermometer is the easiest way to know. It's even more important when you cook thicker burgers. When shopping, look for a quick reading, a thin probe tip and a display that's easy to read over a hot pan. See our instant-read thermometer pick.

5. A cheese melting dome

Here's the diner trick: add cheese right after the flip, squirt a little water on the griddle beside the patty, and cover. The trapped steam melts American cheese into a glossy layer in seconds. A dome is wide, lightweight and easy to grab with one hand. See our cheese melting dome pick.

The budget starter kit

Just getting started? These three tools cover the essentials. Add a press and a dome later if you find yourself making smash burgers every week.

• A cast iron skillet for the crust.
• A heavy-duty spatula for smashing (with a second spatula on top) and scraping.
• An instant-read thermometer for food safety and consistency.

How to use your kit

1. Roll cold 80/20 beef into loose balls and keep them in the fridge until the pan is ready.
2. Preheat your griddle or skillet until it just starts to smoke, with a thin film of high smoke point oil.
3. Place a ball, top with parchment and smash hard to about a quarter inch thick.
4. Season, cook until the edges are deeply browned, then scrape under and flip.
5. Add cheese, steam briefly under the dome, and check the temperature.
6. Stack on a toasted bun and serve right away.

Caring for your gear

• Cast iron and carbon steel: scrape while warm, rinse, dry completely on the burner, and wipe on a thin layer of oil.
• Spatula and press: wash and dry promptly, and check the maker's instructions before putting anything in the dishwasher.
• Thermometer: wipe the probe clean between checks and after cooking, and never submerge it unless it's rated for that.

FAQ

What's the one tool I should buy first?

A stiff, sharp-edged griddle spatula. It scrapes up the crust, flips cleanly and can smash too. Most kitchens already have a pan that will work to start.

Can I make smash burgers in a regular nonstick pan?

It's not ideal. Smash burgers need very high heat and hard metal scraping, which most nonstick coatings aren't designed for. Cast iron or carbon steel gives a better crust.

Do I need a thermometer for thin smash burgers?

Thin patties cook quickly, so many cooks go by color. A thermometer is the only reliable way to confirm 160°F, and it's essential once you cook thicker burgers.

Can I use this kit on an outdoor grill?

Yes, if you have a flat surface. A carbon steel griddle or cast iron skillet can sit on a gas or charcoal grill. Smash burgers won't work directly on grill grates.
