1/8 teaspoon cayenne pepper
Salt and black pepper to taste

Step-by-Step Instructions

Expert Tips

To achieve the best results with your Smash Burger Sauce Recipe, always use a high-quality mayonnaise as your base, as this provides the necessary richness. If you prefer a smoother consistency, ensure your spices are finely ground. Another pro tip is to let the sauce chill in the refrigerator for an hour before use; this cold temperature provides a refreshing contrast to a hot, seared burger patty. Don’t be afraid to adjust the ratios—add a splash more pickle brine if you enjoy extra acidity, or a pinch more cayenne if you want a lingering heat.

There are many ways to tweak this recipe to make it your own. For a garlicky twist, stir in one small clove of grated garlic or a pinch of garlic powder. If you prefer an oniony profile, add a tablespoon of very finely minced shallots or white onion. To increase the umami depth, try adding a teaspoon of Worcestershire sauce or a half-teaspoon of fish sauce. If you do not have dill pickle brine on hand, you can substitute it with white vinegar, apple cider vinegar, or fresh lemon juice to maintain that essential tang. For a smoky version, swap the cayenne pepper for chipotle chili powder.

Serving Suggestions

While this sauce is designed for smash burgers—especially when served on a toasted brioche or seeded bun—it is incredibly versatile. Use it as a dipping sauce for crispy french fries, onion rings, or sweet potato wedges. It also pairs beautifully as a spread for fried fish sandwiches or as a zesty dressing for a wedge salad. If you are making plant-based burgers, this sauce works perfectly with Impossible or Beyond patties to replicate a traditional fast-food flavor profile.

This sauce should be stored in an airtight container or a glass jar in the refrigerator. It will stay fresh and flavorful for up to one week. Because this is a mayonnaise-based sauce, freezing is not recommended as the emulsion will break upon thawing, resulting in an oily texture. This sauce is intended to be served cold or at room temperature, so no reheating is required.
