Why Smash Burgers Need a Special Sauce

This crust produces richer flavor than many traditional burgers.
Crispy Texture
Smash burgers have crispy edges that benefit from a creamy sauce.
Thin Patties
Because smash burgers are thinner, the sauce plays a larger role in the overall flavor profile.
Simple Toppings
Many smash burgers use minimal toppings, making the sauce even more important.
For these reasons, the best smash burger sauce emphasizes balance rather than overwhelming the burger with excessive sweetness or spice.
