A great smash burger sauce recipe can transform a good burger into an unforgettable one. At Benny’s Smash Burgers in Plantation, FL, the sauce is not an afterthought. It is the finishing detail that ties together the crispy smashed patty, the soft toasted bun, and the cold crunch of fresh toppings. After countless requests from our regulars, we are pulling back the curtain on exactly what goes into that creamy, tangy, slightly smoky special sauce that keeps people coming back to 1023 S. University Dr. week after week.
In this guide you will find the full smash burger sauce recipe we use as our base, three flavor variations to match different palates, and the tips that make or break the application. Whether you are making burgers at home or just want to understand what makes the Benny’s menu taste the way it does, this breakdown covers everything.
What Makes a Smash Burger Sauce Different
Smash burger sauce is not the same as a standard burger sauce, a thousand island dressing, or plain mayo. The distinction matters because smash burgers have a very specific flavor profile. The intense Maillard crust on the patty, the caramelized onions smashed into the beef, and the molten American cheese create a rich, savory base that calls for a sauce with real acidity, a little sweetness, and a clean finish.
Classic thousand island dressing is too sweet and too chunky. Plain aioli is too mild. The ideal smash burger sauce recipe sits in the middle: creamy enough to coat the bun and hold the toppings in place, tangy enough to cut through the fat, and seasoned enough to hold its own against the char on the patty. If you have ever eaten at Benny’s and wondered what that sauce is, this is the closest you will get to replicating it at home.
The Classic Smash Burger Sauce Recipe
This is the foundation. Every variation below starts here. The measurements below make enough for eight to ten burgers and will keep in the refrigerator for up to one week in an airtight container.
Ingredients
- 1/2 cup real mayonnaise (Duke’s or Hellmann’s, not light)
- 2 tablespoons ketchup
- 1 tablespoon yellow mustard
- 1 tablespoon dill pickle brine (straight from the jar)
- 1 teaspoon white wine vinegar
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon fine sea salt
- 1/4 teaspoon black pepper
- 1 teaspoon sugar (optional, balances acidity)
Instructions
- Combine all ingredients in a small bowl.
- Whisk until fully smooth and uniform in color. There should be no streaks of ketchup or mustard remaining.
- Taste and adjust. If you want more tang, add another half teaspoon of pickle brine. If you want more heat, add a pinch of cayenne. If the acid is too sharp, add the optional teaspoon of sugar.
- Cover and refrigerate for at least 30 minutes before using. The rest time allows the garlic powder and smoked paprika to bloom in the fat of the mayonnaise. The sauce tastes noticeably better after 30 minutes than it does fresh.
- Apply with a spoon or squeeze bottle to both bun halves before building the burger.
At Benny’s, we spread the sauce on both the top and bottom bun. The bottom bun gets a slightly heavier hand because the patty sits directly on it and needs something to absorb a bit of the juice from the meat. The top bun gets a thinner layer that holds the toppings in place without making the whole thing slip.
Three Variations Worth Knowing
The classic recipe above works for most situations. But depending on what you are building, these three variations will serve you better in specific cases.
Spicy Smash Burger Sauce
Start with the classic base and add one tablespoon of hot sauce (Cholula or Texas Pete work well), one teaspoon of chipotle powder, and two teaspoons of finely minced pickled jalapenos. The chipotle powder adds smokiness in addition to heat, which pairs well with beef that has a heavy crust from the smashing technique. This is the variation we recommend if you are topping your burger with pepper jack cheese instead of American.
Smoky BBQ Smash Sauce
Replace the ketchup and yellow mustard in the base recipe with two tablespoons of good quality BBQ sauce and one teaspoon of Worcestershire sauce. Keep everything else the same. The Worcestershire adds depth and a slight umami note that complements the beef without overwhelming it. This version pairs well with a burger that has crispy bacon and sharp cheddar instead of American cheese.
Garlic Herb Smash Sauce
For a lighter, more refreshing take, replace the smoked paprika with one teaspoon of dried dill and add one tablespoon of finely minced fresh chives. Use lemon juice in place of white wine vinegar. This version is less sweet and more herb-forward, which makes it an excellent match for a turkey or chicken smash patty if you are going that route. It also works well as a dipping sauce for fries on the side.
The Role of Sauce in a Smash Burger vs. a Regular Burger
If you have read our breakdown on smash burgers vs. regular burgers, you already know that the smash technique produces a flatter, crispier patty with more surface area in contact with the griddle. That difference in geometry matters when it comes to sauce.
A thick, juicy burger patty is self-basting. The juice runs down through the stack and keeps everything moist. A smash burger patty, which is thin and fully crisped on both sides, does not release juice in the same way. The sauce has to carry more of the moisture load, which is why the recipe above is slightly more mayonnaise-forward than a typical burger sauce. The fat in the mayo compensates for the drier patty and gives the bite the lubrication it needs.
This is also why the brine from the pickle jar is not just a seasoning choice. The acidity and moisture from the brine keep the sauce from feeling heavy on the palate, even though it is technically a high-fat condiment. Every element in the recipe is doing structural work, not just adding flavor.
How to Build the Burger Around the Sauce
A great smash burger sauce recipe only delivers results if the rest of the burger is built correctly. Here is how we think about it at Benny’s.
Toast the Bun Before You Apply
A cold, soft bun will absorb the sauce too quickly and turn soggy by the time the burger reaches the table. Always toast the bun cut-side down on a flat top or in a skillet with a thin film of butter until the face is golden and slightly firm. That crust creates a barrier that slows absorption. The sauce stays on the surface where it belongs instead of sinking into the bread.
Apply Sauce at Room Temperature
Cold sauce straight from the refrigerator will cool down the patty faster than you want. Pull the sauce out 10 minutes before you start cooking so it is at or near room temperature when you apply it. The difference in the final bite is noticeable. The sauce integrates with the warmth of the patty instead of fighting it.
Do Not Overload
The instinct when you have a good sauce is to use a lot of it. Resist that instinct. A tablespoon per bun half is usually enough. The sauce should be present in every bite without dominating. When you can taste the patty, the cheese, the onion, and the sauce all together in equal measure, that is the target. If the sauce is the only thing you taste, you have used too much.

Smash Burger Sauce FAQ
What is smash burger sauce made of?
Classic smash burger sauce is made from mayonnaise, ketchup, yellow mustard, pickle brine, vinegar, garlic powder, onion powder, smoked paprika, salt, and pepper. The base is mayonnaise and the acidity comes from the pickle brine and vinegar. Most recipes also include a small amount of sugar to balance the tang.
Can I make smash burger sauce ahead of time?
Yes, and it is actually better when made ahead. The sauce needs at least 30 minutes to rest so the dry spices can bloom in the fat of the mayonnaise. You can make it up to five days in advance and store it in an airtight container in the refrigerator. Stir before each use as the vinegar may settle slightly at the bottom.
What is the difference between smash burger sauce and Big Mac sauce?
Big Mac sauce contains sweet pickle relish, which makes it chunkier and sweeter than most smash burger sauces. Smash burger sauce typically uses pickle brine rather than relish, which gives it a cleaner, more liquid texture that coats the bun evenly. Smash burger sauce also tends to lean more on mustard and smoked paprika for savory depth, while Big Mac sauce is intentionally sweeter.
How much sauce should I put on a smash burger?
About one tablespoon per bun half, or two tablespoons total per burger. Apply it to the cut face of the toasted bun using a spoon or squeeze bottle. The sauce should cover the surface but not pool or drip heavily. When the burger is assembled and pressed together, the sauce should be visible at the edges without running out.
Is smash burger sauce the same as fry sauce?
They share similar base ingredients but the proportions and seasoning differ. Fry sauce is typically just mayo and ketchup with a little vinegar. Smash burger sauce adds mustard, pickle brine, garlic powder, onion powder, and smoked paprika to create a more complex flavor profile designed specifically to complement the char on a smash patty. Fry sauce works fine as a dipping sauce but lacks the depth needed to anchor a burger.
