What Makes a Smash Burger a Smash Burger?
These truly are a family staple for us now that we’ve started making them! A smash burger is exactly what it sounds like – a burger that is smashed down until it’s thin and crispy! As a result, smash burgers are typically cooked until well done, unlike thick burgers that can range from rare to well done.
Don’t worry, though! This recipe is far from bland or dry. Smashing the beef increases its surface area, locking in the natural juices and flavor. Paired with the sweet onions and tangy sauce, the burgers are juicy, savory, and completely irresistible. Plus, they cook super quickly, making them perfect for busy weeknights or feeding a large crowd!
Load them up with your favorite toppings, and you’ll never go back to restaurant versions again.

Ingredients Needed and Substitutions
*Scroll down to the recipe card for the full recipe and ingredient list!
Smash Burgers
- Onion: I like to use white onion for a slightly more savory taste, but yellow onions will also work.
- Ground Beef: For the best results, I recommend using 80/20 beef. This helps keep the burgers moist and juicy.
- Seasonings: Use salt and pepper, or opt for your favorite burger seasoning.
- Yellow Mustard: This coats the buns, adding a delicious tangy taste. Feel free to substitute Dijon mustard if preferred!
- Cheese: Use slices of cheese that melt well such as cheddar, muenster, provolone, or American cheese. Or, use your favorite plant-based cheese if you need to keep this recipe dairy-free.
- Toppings: Mix and match all your favorite burger toppings such as burger sauce (see below), pickle chips, lettuce, and tomato slices.
Burger Sauce
*If you don’t want to make it, I love this one!
- Mayonnaise: Use your favorite store-bought mayonnaise, or make homemade Paleo mayo!
- Mustard: Yellow mustard or Dijon mustard both work well.
Ketchup: I like to use a low-sugar ketchup, but whatever you like best will taste great. - White Vinegar: This adds just a touch of tangy flavor. Feel free to substitute apple cider vinegar.
- Seasoning: Garlic powder, paprika, and salt create a savory flavor with lots of depth.
- Hot Sauce: This is optional, but I love to add a dash of hot sauce for a touch of heat!
- Relish: Again, this is optional but really takes the flavor of the sauce over the top!

How to Make Smash Burgers
- Portion the beef: Divide the ground beef, and form the meat into 3-ounce balls.
- Cook the onions: Spread the onions out on a hot griddle, flat top, or cast iron pan. Cook for 1-2 minutes over medium heat, adding oil as needed so they don’t stick or burn.

Tools for Success
This recipe is already virtually failproof, but the following tools help ensure your burgers turn out crisp and flavorful with ease, no matter how you’re cooking them!
- Flat Top Accessories – I love cooking on a flat top, especially when I’m making several burgers at once, and these accessories allow for easy cooking, flipping, and cleanup.
- Griddle Insert – This makes it easy to cook on a grill without the thin patties sliding right through the grates. You can also use it to make eggs, pancakes, and more!
- Griddle and Grill Press – Of course, you can use a metal spatula to flatten your burgers if needed. However, I’ve found that these tools create the super thin, restaurant-quality patties we want.
- Kitchen Scale – Use this to portion the beef mixture evenly so all your burgers cook evenly.
Serving Suggestions
If you want to keep this recipe low-carb and gluten-free, feel free to skip the bun, and use a lettuce wrap instead. Then, create a complete meal with sides like:
- Baked Sweet Potato Fries
- Sweet Cucumber Salad
- Grilled Sweet Potatoes
- Air Fryer Asparagus
- Mediterranean Quinoa Salad

FAQs
Can I make this smash burger recipe ahead of time?
Yes, you can prep the burger patties 1-2 days in advance and the burger sauce up to 3 days ahead of time. Store them in separate airtight containers in the fridge. Then, reheat the burgers in the microwave or a cast iron skillet over medium-high heat, and assemble with your favorite toppings when you’re ready to eat.
Can I make this recipe without beef?
I haven’t tested it out, but ground bison, ground turkey, or ground chicken should work. Just be sure to adjust the cooking time as needed, and keep in mind that the taste and texture of the burgers will change slightly!
Why are my smash burgers tough?
Using meat leaner than 80% can cause your burgers to be tough. Also, be sure not to press the patties after they begin to cook. This can squeeze out excess juice, making the meat dry.
