How to Make The Ultimate Smash Burger
Let me show you how to make these incredibly delicious Smash Burgers:
Mix Secret Sauce
- I mix the secret sauce ingredients (mayo, ketchup, mustard, pickle relish, onion powder, and smoked paprika) in a bowl.
- I store it in the refrigerator until ready to use.
Form Burger Balls
- Very gently, I form the ground beef into rough balls - just enough to give them shape without compressing the beef. This is important for achieving those crispy edges.
Heat Griddle/Skillet
- I heat my grill to 400 degrees F (200°C) on medium-high direct heat.
- I place a large cast iron skillet on the grill or use the flat, griddle side of grill grates. I give my surface a few minutes to get nice and hot.
Cook Onions
- I add half of the butter to the skillet and let it melt.
- I add the onions and let them cook until translucent.
- I remove the onions from the skillet and set them aside.
Smash and Cook Burgers
- I add more butter to the skillet.
- Working in batches, I place the burger balls on the hot skillet.
- I immediately flatten them with a sturdy metal spatula to about ½-inch thick. This is the "smashing" part!
- I sprinkle the burgers with salt and pepper.
- I flip the burgers when the edges begin to form a nice, crispy crust.
- Add cheese and continue to cook.
- I remove the burgers once both sides have achieved those crispy, griddled edges.
Assemble Burgers
- To assemble the burgers, I slather the bun with the secret sauce.
- Next, I add a patty and top it with the grilled onions.
- Optionally, I add tomato and pickles.
Tips and Tricks for the BEST Smash Burgers
Here are my secrets for making these burgers truly the ultimate:
- Use 80/20 Ground Chuck: The higher fat content in 80/20 ground chuck is essential for juicy, flavorful burgers.
- Don't Overwork the Meat: Handle the ground beef gently when forming the balls. Overworking the meat will result in tough burgers.
- Hot Skillet/Griddle: Make sure your cooking surface is very hot before adding the burgers. This is crucial for achieving those crispy edges.
- Smash Thin: Don't be afraid to smash the burgers really thin - this creates maximum surface area for browning.
- Use a Sturdy Spatula: You'll need a sturdy metal spatula to properly smash the burgers.
- Don't move the burger Let it sit for 2 minutes
How to Serve
These Smash Burgers are perfect for:
- Cookouts and Barbecues: A fun and delicious alternative to traditional burgers.

Ingredients
Scale
For the Burgers:
- 2 pounds ground chuck (80% lean / 20% fat)
- ½ stick (4 tablespoons) unsalted butter, divided
- 1 medium yellow onion, finely chopped
- 1 tablespoon kosher salt, divided
- ½ tablespoon coarsely ground black pepper, divided
- 4 hamburger buns (or your favorite burger buns)
- 4 slices cheese (cheddar, American, or your preference), optional
- Tomato slices, optional
- Pickles, optional
For the Secret Sauce:
- ½ cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon yellow mustard
- 1 tablespoon pickle relish (sweet or dill)
- ¼ teaspoon onion powder
- ¼ teaspoon smoked paprika
Instructions
- Make Secret Sauce: In a small bowl, combine the mayonnaise, ketchup, mustard, pickle relish, onion powder, and smoked paprika. Whisk until well combined. Cover and refrigerate until ready to use.
- Prepare Burger Meat: Gently divide the ground chuck into 4 equal portions (about 8 ounces each). Very gently form each portion into a loose ball. Do not overwork or compress the meat. The goal is to keep the meat as loosely packed as possible for the best smash.
- Preheat Grill/Skillet: Preheat your grill to medium-high heat (about 400°F / 200°C) with direct heat. Place a large cast-iron skillet on the grill grates, or if your grill grates have a flat griddle side, flip them over and use that. Let the skillet or griddle get very hot.
- Cook Onions: Add half of the butter (¼ stick or 2 tablespoons) to the hot skillet/griddle. Let it melt. Add the finely chopped onions and cook, stirring occasionally, until they are translucent and softened, about 5-7 minutes. Remove the onions from the skillet and set them aside.
- Smash Burgers (Batch 1): Add the remaining butter (¼ stick or 2 tablespoons) to the skillet. Working in batches (2 burgers at a time is usually best), place two of the loosely formed ground beef balls onto the hot skillet/griddle. Immediately use a sturdy, flat metal spatula (ideally a burger press or a spatula reinforced with another spatula) to firmly smash the burgers down to about ½-inch thickness. Season the smashed patties generously with half of the salt and half of the pepper.
- Cook Burgers (First Side): Cook the smashed burgers, undisturbed, for 2-3 minutes, or until the edges are very crispy and browned.
- Flip and Cook (Second Side): Carefully flip the burgers. If adding cheese, place a slice on top of each patty. Continue to cook for another 1-2 minutes, or until the cheese is melted and the burgers are cooked to your desired level of doneness.
- Repeat with Remaining Burgers: Remove the cooked burgers from the skillet and set aside. Repeat steps 5-7 with the remaining two ground beef balls, adding more butter to the skillet if needed, and using the remaining salt and pepper.
- Assemble Burgers: Spread the secret sauce generously on both the top and bottom buns. Place a cooked smash burger patty on the bottom bun. Top with the grilled onions, and any optional toppings like tomato slices and pickles. Add the top bun.
- Serve: Serve the smash burgers immediately.
Notes
- Ground Chuck: 80% lean / 20% fat ground chuck is essential for juicy and flavorful smash burgers.
- Do Not Overwork Meat: The key to a great smash burger is to handle the meat as little as possible before smashing. Overworked meat will result in tough burgers.
- Hot Skillet/Griddle: A very hot cooking surface is crucial for creating the crispy, lacy edges.
- Smashing Technique: Use a sturdy, flat metal spatula (a burger press is ideal) and press down firmly and evenly on the burger balls immediately after placing them on the hot surface.
- Cooking in Batches: Cooking the burgers in batches prevents overcrowding the pan, which would lower the temperature and steam the burgers instead of searing them.
- Serving Suggestions: Serve these smash burgers with your favorite burger sides, such as french fries, onion rings, or a salad.
