Fry sauce is a creamy, tangy condiment made from a simple blend of ketchup and mayonnaise, sometimes with a splash of pickle juice or vinegar. It is a beloved regional staple in Utah and the surrounding Mountain West, where it is served with french fries, onion rings, and even burgers. Its appeal lies in its perfect balance of sweet, savory, and tangy flavors, and its versatility makes it a favorite for dipping everything from fries to chicken tenders.
Ingredients
- 1/2 cup (120 g) mayonnaise
- 1/4 cup (60 g) ketchup
- 1 teaspoon (5 ml) dill pickle juice (optional)
- 1/2 teaspoon (2.5 g) garlic powder
- 1/4 teaspoon (1.5 g) onion powder
- 1/8 teaspoon (0.5 g) smoked paprika (optional)
- Salt and freshly ground black pepper, to taste
Instructions
- In a small bowl, combine the mayonnaise, ketchup, pickle juice (if using), garlic powder, onion powder, and smoked paprika (if using).
- Whisk until the mixture is smooth and well blended. The color should be a uniform pink-orange.
- Taste and season with salt and pepper as needed. Keep in mind that ketchup and pickle juice are already salty, so add salt sparingly.
- Cover and refrigerate for at least 30 minutes before serving to allow the flavors to meld. This step is optional but recommended.
- Serve as a dip for fries, onion rings, or as a spread for burgers and sandwiches.
Tips
- Substitutions: Use Greek yogurt or sour cream in place of some or all of the mayonnaise for a tangier, lighter sauce. For a vegan version, use vegan mayonnaise and ensure your ketchup is vegan (most are).
- Storage: Store fry sauce in an airtight container in the refrigerator for up to 1 week. Stir well before using, as separation may occur.
- Common mistake: Don’t overdo the ketchup. The classic ratio is about 2 parts mayonnaise to 1 part ketchup. Too much ketchup makes it taste like sweet tomato soup, not fry sauce.
- Flavor boost: A dash of hot sauce or a pinch of cayenne adds a nice kick. For a more authentic Utah-style sauce, some people add a few drops of liquid smoke.
Serving Suggestions
Fry sauce is traditionally served with hot, crispy french fries—whether they are thin, steak-cut, or curly. It also pairs wonderfully with onion rings, tater tots, and sweet potato fries. Beyond fries, use it as a spread on burgers, a dip for chicken nuggets or fish sticks, or even as a dressing for a simple coleslaw.
Variations
- Spicy Fry Sauce: Add 1-2 teaspoons of sriracha or your favorite hot sauce to the base recipe for a spicy kick.
- Smoky Fry Sauce: Stir in 1/2 teaspoon of liquid smoke or an extra 1/4 teaspoon of smoked paprika for a barbecue-inspired flavor.
- Herbed Fry Sauce: Mix in 1 tablespoon of finely chopped fresh dill, chives, or parsley for a fresh, garden-like taste.
- Honey Mustard Fry Sauce: Replace the ketchup with 2 tablespoons of yellow mustard and 1 tablespoon of honey for a sweet and tangy twist.
Storage and Reheating
Fry sauce is best served cold or at room temperature. Store it in an airtight container in the refrigerator for up to 1 week. Because it is a cold sauce, there is no need to reheat it; just take it out of the fridge about 10 minutes before serving to take the chill off. If the sauce separates after sitting, simply stir it well to bring it back together. Do not freeze fry sauce, as the mayonnaise will break and become watery upon thawing.
Frequently Asked Questions
Why is it called fry sauce? The name is straightforward: it is a sauce for fries. The term became popular in the 1940s in Utah, where the condiment was served in local drive-ins and burger joints.
Is fry sauce the same as thousand island dressing? No, but they are similar. Thousand island dressing usually includes chopped pickles, onions, and sometimes hard-boiled eggs, making it chunkier. Fry sauce is smooth and simpler, typically just ketchup and mayonnaise.

What is the best ratio of ketchup to mayonnaise? Most people prefer a 2:1 ratio of mayo to ketchup, but it is a matter of taste. Some like it more tomatoey (1:1), while others like it creamier (3:1). Start with 2:1 and adjust from there.
How long does homemade fry sauce last? When stored in an airtight container in the refrigerator, it will stay fresh for up to 1 week. Always check for any off smells or mold before using.
Can I use this sauce as a burger spread? Absolutely. In fact, many Utah burger joints use fry sauce as a signature spread on their burgers. It adds a creamy, tangy flavor that complements the meat and cheese.
