Chicago Fry Sauce is the better-tasting version of Special Sauce. Inspired by the 7 classic toppings of a Chicago-style hot dog, we blend mustard, relish, pickles, tomatoes, onions, sport peppers, and celery salt into a smooth, craveable condiment. Then we take it further: Chicago Fry Sauce = Chicago Sauce + Mayo + Ketchup. The result? A sauce that outshines yum yum sauce, special sauce, secret sauce, Big Mac sauce, and even remoulade — versatile, bold, and downright delicious. Perfect for dunking fries, onion rings, or tots, spreading onto burgers and fried chicken sandwiches, or swirling into potato salad and slaw. Made in small batches in Chicago with clean, high-quality ingredients, it’s the sauce that makes everything better.
