Crispy Smash Burgers with American Cheese (Easy Cast Iron Recipe)

Every once in a while I make a dish that instantly becomes the new favorite, and these crispy smash burgers are the latest. After one bite, my husband declared them “better than a restaurant burger,” which is about the highest praise a homemade burger can get around here.

What makes smash burgers so special is how you cook them. The beef hits a blazing hot cast iron skillet, gets pressed thin, and forms those irresistible crispy, caramelized edges while the center remains juicy and flavorful. Add a slice of melty American cheese and stack the patties on a soft bun with your favorite toppings, and you’ve got a burger that tastes like it came straight from a diner.

The best part? They come together in just minutes and use simple ingredients you probably already have on hand. Once you try them, there’s a good chance they’ll become your new favorite burger too.

Enjoy!

Ingredients

This recipe keeps things simple and classic so the flavor of the beef really shines.

Ground Beef – I like using 85/15 for the perfect balance of flavor and juiciness.

Kosher Salt & Freshly Ground Black Pepper – Simple seasoning that lets the beef develop that signature smash burger flavor.

American Cheese – The classic choice for smash burgers because it melts beautifully and creates that creamy, diner-style finish.

Hamburger Buns – Soft buns work best since the crispy patties are thin and stack nicely.

Optional Toppings – Mayonnaise, mustard, ketchup, lettuce, pickles, sliced tomatoes, and onions are all great choices depending on how you like your burger dressed.

-- Let’s Make It Together

Start by dividing the ground beef into eight small portions. Very loosely form each portion into a ball—don’t pack the meat tightly or the burgers will lose that tender texture.

Heat a cast iron skillet or griddle over high heat until it’s very hot. Place the beef balls onto the skillet and immediately use a sturdy spatula or bench scraper to smash them down as thin as possible.

Season the patties with salt and pepper and cook for about one minute, until the edges start to brown and crisp.

Flip the patties, season the second side, then place a slice of American cheese on top. Let the patties cook another 30–60 seconds, just until the cheese melts.

Stack two patties per bun, add your favorite toppings, and serve immediately.

-- Perfecting the Cooking Process

The secret to perfect smash burgers is high heat and pressing the patties immediately after they hit the skillet. This creates maximum contact with the hot surface, which is what forms those irresistible crispy, caramelized edges while the inside stays juicy. Resist the urge to press the burgers again after flipping—doing so can squeeze out the flavorful juices.

-- Add Your Touch

One of the best things about smash burgers is how easy they are to customize.

Try adding crispy bacon, sautéed onions, or sliced avocado for extra flavor. A swipe of burger sauce or garlic aioli can take things up a notch, while shredded lettuce and pickles add a nice crunch.

You can also toast the buns lightly in the skillet for a little extra texture. However you dress them up, these burgers are incredibly versatile and easy to make your own.

Before You Start

Do I need a cast iron skillet?
Cast iron works best because it holds high heat well, but a heavy stainless steel skillet or flat griddle will also work.

Why are smash burgers so thin?
Pressing the burgers thin increases surface contact with the hot pan, which creates the crispy edges that make smash burgers famous.

Can I make these ahead of time?
Smash burgers are best cooked and served immediately since they cook very quickly and taste best fresh off the skillet.

What’s the best beef for smash burgers?
Ground beef with a little fat—around 80/20 or 85/15—creates the juiciest burgers and helps develop that crispy crust.
