Recipe Science

  • Pressing the burger patty onto a hot griddle maximizes surface contact, creating a flavorful crust through the Maillard reaction.
  • The high heat quickly sears the outside, locking in juices and keeping the inside of the patty moist and tender.
  • Thin patties cook rapidly, which helps maintain their juiciness while developing a crispy, caramelized exterior.

Why It Works

We all love a thick and juicy stovetop burger, but you’re in for a culinary treat if you haven’t tried a smash burger! As the name hints, the burger patty is formed into a ball, added to a hot pan, then pressed down until thin. The result is a more flavorful browned crust on the surface with crisp edges. It’s absolutely delicious!

Typically a cast iron press is used for smashing the burgers down, but I’ll show you other simple techniques with the tools you already have. The patties start smaller since they will expand with flattening. Single or double them up and stack them on soft toasted buns with a special sauce and your favorite toppings. Serve with onion rings, tater tots, or French fries for the ultimate experience!

Ingredients You’ll Need

Ingredients needed to make a smash burger recipe.
  • Ground Beef: Use ground chuck, which is 80% lean ground beef. It has the proper ratio of meat to fat, making for juicy and flavorful patties easy to smash down. There should be at least 20% fat, or it will be hard to press thin.
  • Seasoning: Use a simple combination of salt and pepper. You can also use garlic or onion powder for extra seasoning on the burger patties.
  • Cheese: American cheese will give the best melt and is often used in burger joints and diners. However, mild or sharp cheddar is a delicious choice for a stronger taste.
  • Burger Buns: Brioche buns are my top choice because they are sturdy, tender, and rich in egg flavor. Plain hamburger buns, potato buns, or sesame topped work well. Don’t purchase the jumbo size; the patties will be too small.
  • Sauce: The smash burger sauce recipe is a simple combination of mayonnaise, yellow mustard, and sweet pickle relish.

See the recipe card below for all ingredients and measurements (US and metric).

Ingredient Substitutions

  • Herbs and Spices: Herbs like rosemary, oregano, or thyme add a nice herbaceous note. Add dried alliums like garlic powder and onion powder. Sprinkle on a little smoked paprika for a barbecued flavor. For a shortcut, make a batch of my hamburger seasoning.
  • Spicy: Add chili powder or cayenne for a spicy kick. Give this cajun seasoning a try!
  • Meat: For your next smash burger, try lamb, bison, pork, turkey, or chicken. Mix ground beef with Italian sausage to enhance the savory taste.
  • Umami: Add 1 to 2 teaspoons of soy sauce, coconut aminos, Worcestershire sauce, miso paste, or anchovy paste to increase the beefy flavor of the meat.
  • Toppings: Avocado, butter lettuce, arugula, sundried tomatoes, fresh tomatoes, caramelized onions, pickled red onions, crispy bacon, grilled pineapple, or a fried egg.
  • Cheese: Add cheddar, brie, mozzarella, gouda, swiss, provolone, blue cheese, or feta.
  • Sauces: If you like a tomato-flavored spread, try my grilled burgers recipe for the sauce. Barbecue sauce, ranch, green goddess, or homemade teriyaki sauce add a delicious twist.
  • Hamburger Buns: Brioche, sesame, potato, plain, or pretzel buns.

How to Make Smash Burgers

Mayonnaise, mustard, and sweet relish in a bowl with a whisk.

Step 1: Make the Sauce

A good burger always benefits from a sauce to complement the meat. You just need to mix three ingredients: mayonnaise, yellow mustard, and sweet pickle relish.

Since the burgers are rich from 80% lean ground beef, I like adding mustard-based sauce.

Quick Substitutions: Dijon mustard is a good substitute for a less tangy flavor. Dill pickles can be chopped up to substitute the relish. I recommend adding ½ to 1 teaspoon of honey to balance the pickled vegetable.

Step 2: Form the Patties

Divide the ground beef into 4-ounce portions. Gently form them into a round shape until they just hold together. You don’t want to compact the proteins, or it will make it difficult to press down. Overworking the muscle fibers also causes the proteins to contract and squeeze out more juices. Lightly flatten the top, then season with salt and pepper on both sides.

Pro Tip: Refrigerate until ready to cook. Don’t let the burgers be at room temperature; otherwise, the fat will melt too quickly, causing a dry taste and a less crisp surface. If you’re going to add two patties, like the famous double-double at In-N-Out Burger, then make eight patties.

Step 3: Heat the Pan

Grease the pan with vegetable oil to prevent sticking and kickstart browning. Heat the pan over medium heat to ensure it’s evenly heated throughout.

Use a large, heavy-bottomed pan for even cooking and the best crust formation. A cast iron skillet is my first choice, but a stainless steel pan works, too. The crust sticks more to the stainless steel pan, so make sure the pan is preheated and a crust forms on it to make it easier to flip.

Pro Tip: Avoid nonstick pans; the high heat required will ruin the coating. A sizeable hot cast iron griddle or outdoor barbecue with a flat surface works well for making a larger batch. Smash burgers should not be made on barbecue grates, or they will fall through when pressed.

Step 4: Cook the Burgers

When ready to cook the patties, add the beef balls one at a time to allow for spreading when pressed. Don’t wait longer than 30 seconds to smash the burgers down with a sturdy, flat metal spatula. Otherwise, the fat will warm up and release its juices.

Cook each burger until a golden crust forms, about 2 minutes. Use the edge of the spatula to scrape and release the patty from the pan. Flip the burger and cook for about 1 minute.

You want maximum contact with the bottom of the hot pan. It helps to use another spatula or meat pounder to press straight down on the patties. They should be about 1/2-inch thick and 4 inches wide.

Step 5: To Serve

Toast the buns in the toaster oven, or butter and toast on the pan until warm and the cut side is crisp—layer on the smash burger sauce, pickles, lettuce, patty, tomato, and onion.

Now that you know how to make a smash burger have fun customizing it. There are endless ways to switch up the sauces and toppings. Make a burger bar for your next party. Guests will have a blast building their own creations.

Tools for Making Smash Burgers

The ideal tool for smashing the beef is a round smashed burger press. It’s wide enough to make 4 to 5-inch wide patties, and the handle makes it easy to push down just once. However, here are some other options with tools you already have in your kitchen:

  • Cast Iron Skillet: Use the bottom of a mini cast iron skillet, 4 to 5 inches in size, to push down on the patty.
  • Measuring Cups: Use the bottom of a 1 or 1-1/2-cup measuring cup. You must quickly press down a few times since it’s smaller than 4 inches wide.
  • Spatula: Use a flat metal spatula to push down on the patties. It helps to use a meat pounder or another spatula to push straight down on the top of the blade to flatten the meat.
  • Parchment Paper: Cut 4 to 5-inch sized squares. Place a piece on top of the burger before flattening it with the desired tool. This helps to prevent sticking. If you feel more comfortable flattening the patties before adding them to the pan, do this in between two squares or parchment, then transfer them to the pan.

Frequently Asked Questions

What is the secret to smash burgers?

Use a heavy bottom pan, like cast iron, that is preheated for even and quick surface browning. Immediately smash the burgers to 1/2-inch thick so they stay juicy and develop a delicious crust. Don’t move them so that a crust forms!

How is a smash burger different from a hamburger?

Smashing ground beef into thinner patties creates more surface area for a well-browned crust with crisp edges. These patties only need about 2 minutes to cook per side, as you don’t want them to dry out. Hamburgers are shaped before adding to the pan and not pressed down. These are thicker and less crisp and can have more of a pink center.

Should smash burgers be at room temperature before cooking?

No! The meat should be chilled before cooking. This helps the fat in the ground beef stick together to hold the patty shape. The cold fat also prevents the juices from releasing too quickly, preventing a dry texture.

What creates a flavorful Smashburger?

It’s not loading up the beef with seasonings. As the beef reaches 300ºF, the change in the protein structure and flavor and aroma development occurs. It’s the characteristic smell in burger restaurants. Smashing allows for more surface area contact with the hot pan, creating a crisp and delicious browned crust. Smash the burgers down within 30 seconds to ensure a juicy texture and enough time to brown without overcooking the center of the patties.
