Why You’ll Love Smash Burger Sauce
Creamy, tangy and full of flavor this Burger Sauce is a must anytime we serve Homemade Smash burgers for a delicious condiment! It blends mayo for richness with ketchup and yellow mustard for sweet–savory flavor. We also add in pickle relish, garlic powder, onion powder, and paprika for depth.
The result is a creamy, pink spread that melts into the toasted bun and clings to the crispy edges of a smash burger patty, balancing salty crust with just enough savory flavor.
Chill the sauce for about 30 minutes so the flavors combine, then spread generously and get ready for burger-joint perfection at home!
