What Is Smash Burger Sauce?

Smash burger sauce is a creamy, mayonnaise-based condiment that balances sweet, tangy, savory, and slightly smoky flavors. It’s typically spread generously on both buns of a smash burger.

The idea behind smash burgers is simple: thin beef patties are pressed (“smashed”) onto a hot surface to create a crispy crust through the Maillard reaction. Because the patty is thin and intensely savory, it pairs perfectly with a creamy sauce that adds moisture and contrast.

Unlike basic ketchup and mustard, this special burger sauce blends multiple ingredients into one smooth, balanced spread.
