Fry sauce is a creamy, tangy, slightly sweet dipping sauce made from a simple blend of ketchup and mayonnaise, with a few seasonings to brighten it up. It is a beloved staple in Utah, where it is served with fries, onion rings, and even burgers. This homemade version is quick to whisk together and tastes far fresher than anything bottled, letting you adjust the balance of tang, sweetness, and spice to your liking.
Ingredients
- 1/2 cup (120 g) mayonnaise
- 1/4 cup (60 g) ketchup
- 1 tablespoon (15 ml) dill pickle juice (or white vinegar)
- 1 teaspoon (5 ml) Worcestershire sauce
- 1/2 teaspoon (2.5 g) garlic powder
- 1/2 teaspoon (2.5 g) onion powder
- 1/4 teaspoon (1.5 g) smoked paprika (optional, for a smoky note)
- 1/8 teaspoon (0.7 g) cayenne pepper (optional, for heat)
- Salt and freshly ground black pepper, to taste
Instructions
- In a medium bowl, combine the mayonnaise, ketchup, pickle juice, Worcestershire sauce, garlic powder, onion powder, and smoked paprika and cayenne if using.
- Whisk until completely smooth and uniform. The color should be a light pinkish-orange.
- Taste and season with salt and pepper. Remember that the pickle juice and ketchup add saltiness, so start with a pinch and add more if needed.
- Transfer to a serving bowl or an airtight container. For the best flavor, let the sauce rest in the refrigerator for at least 30 minutes before serving, though it can be used immediately.
Tips
- Substitutions: Use Greek yogurt or sour cream in place of some or all of the mayonnaise for a lighter, tangier sauce. If you don’t have pickle juice, use white vinegar or apple cider vinegar mixed with a pinch of sugar. For a vegan version, use vegan mayonnaise and ensure your Worcestershire sauce is vegan (many brands are, but check the label).
- Adjust the consistency: If you prefer a thinner sauce for drizzling, add a teaspoon of water or milk at a time until it reaches your desired consistency. For a thicker dip, use less ketchup or add an extra tablespoon of mayonnaise.
- Common mistake: Over-salting. The pickle juice and ketchup already contain salt, so taste before adding any. Also, avoid using sweet pickle relish juice, which will make the sauce too sweet and change the texture.
- Make it ahead: The flavors meld and improve after a few hours in the fridge. Make it up to 3 days in advance and store in a sealed jar.
Serving Suggestions
This fry sauce is perfect for dipping hot, crispy french fries, sweet potato fries, onion rings, or tater tots. It also works wonderfully as a spread on burgers, a topping for loaded baked potatoes, or a dip for chicken tenders and mozzarella sticks. For a classic Utah-style meal, serve it alongside a pastrami burger or a scoop of fry sauce with a side of crispy hash browns.
Variations
- Spicy Fry Sauce: Add 1–2 teaspoons of hot sauce (like Sriracha or Frank’s RedHot) or an extra pinch of cayenne pepper.
- Smoky BBQ Fry Sauce: Replace the ketchup with BBQ sauce and add a dash of liquid smoke (if you have it) for a deeper, smokier flavor.
- Herb Fry Sauce: Stir in 1 tablespoon of finely chopped fresh chives, dill, or parsley for a fresh, garden-like taste.
- Honey Mustard Fry Sauce: Mix in 1 tablespoon of Dijon mustard and 1 teaspoon of honey for a sweet-tangy twist.
Storage and Reheating
Store leftover fry sauce in an airtight container in the refrigerator for up to 5 days. The sauce does not need reheating; serve it cold or at room temperature. If it thickens after chilling, stir in a teaspoon of water or milk to loosen it. Do not freeze, as the mayonnaise will separate and become watery upon thawing.
Frequently Asked Questions
Can I use low-fat mayonnaise? Yes, you can use low-fat or light mayonnaise, but the sauce may be slightly thinner and less rich. You may need to add a little extra ketchup or a pinch of sugar to balance the flavor.
How long does fry sauce last? When stored in an airtight container in the refrigerator, it will stay fresh for up to 5 days. Always check for any off smells or changes in texture before using.
Can I make this without pickle juice? Absolutely. Use white vinegar or apple cider vinegar mixed with a pinch of sugar to mimic the tangy-sweet flavor of pickle juice. Start with 1 teaspoon and adjust to taste.
Is fry sauce the same as Thousand Island dressing? No, but they are similar. Thousand Island dressing typically includes chopped pickles, onions, and sometimes hard-boiled eggs, making it chunkier. Fry sauce is smooth and simpler, usually just ketchup and mayonnaise.
Why is my fry sauce too thin? If your sauce is too thin, you may have added too much pickle juice or vinegar. To thicken it, add an extra tablespoon of mayonnaise or a teaspoon of tomato paste and whisk well.
Can I use this sauce as a burger spread? Yes, it is excellent on burgers. It adds a creamy, tangy kick that pairs well with beef, chicken, or veggie patties. Spread it on the bun before adding the patty.
