Why you should make Freddy’s Fry Sauce at home

Get a whole lot more flavor into your life with Freddy’s Famous Fry Sauce! Freddy’s serves some of the best burgers, hot dogs, and chicken tenders, but it’s the famous Fry Sauce for their tots and french fries that really has customers talking. The dipping sauce strikes the perfect balance between creamy, tart, and savory, making it completely addictive.

The Fry Sauce from Freddy’s goes on just about everything, and as an added bonus, the spice blend works wonderfully for seasoning burgers and more. This two-in-one copycat recipe is easy to make and one you’ll want to keep on hand.

Fry Sauce ingredients and their roles in the recipe

For the spice blend, you’ll need:

Paprika (regular, not smoked) – gives the sauce its characteristic reddish color and a mild, slightly sweet pepper flavor.
Garlic powder – provides the aromatic flavor of garlic without any of the harshness that can come from fresh cloves.
Onion powder – imparts the deep, savory notes of onions without the sharpness fresh onions can have.
Ground mustard – adds tang and a subtle bite while letting you control the amount of vinegar in the dip.
Ground black pepper – supplies a mild warmth and a slight bite.
Turmeric – adds color and a bit of earthiness to balance the sauce’s acidity.
Kosher salt – enhances the flavor of the other ingredients.

For the fry sauce, you’ll need:

Full-fat mayonnaise (Duke’s preferred for its tang; Hellmann’s is also an option) – is the base of the sauce and provides richness and some tang.
Ketchup – cuts the fat in the mayo with its acidity and adds sweetness.
Dill pickle juice (from a jar of dill pickles, not sweet pickles) – boosts the tang, thins the sauce, and adds savory elements.
Distilled white vinegar – gives the sauce a clean, bright edge.
The spice blend from above – turns a simple “secret sauce” into something with complex flavors.
