Fry sauce is the creamy, tangy condiment that makes fries, tots, and onion rings disappear. While ketchup is the traditional base, you can make a genuinely delicious fry sauce without it—using roasted red peppers, tomato paste, or even butternut squash for color and depth. These five versions range from a 5-minute pantry staple to a smoky, roasted option, so you can pick the one that fits your craving and what you have on hand.
Ingredients
For the Classic No-Ketchup Fry Sauce (makes about 1 cup / 240 ml):
- 1/2 cup (120 g) mayonnaise
- 2 tablespoons (30 ml) tomato paste
- 1 tablespoon (15 ml) white vinegar
- 1 teaspoon (5 g) sugar
- 1/2 teaspoon garlic powder
- 1/4 teaspoon onion powder
- 1/4 teaspoon smoked paprika (optional)
- Salt to taste
- 1–2 tablespoons (15–30 ml) water, to thin
For the Roasted Red Pepper Version:
- 1/2 cup (120 g) mayonnaise
- 1/4 cup (60 g) roasted red peppers, drained and chopped
- 1 tablespoon (15 ml) red wine vinegar
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon salt
For the Butternut Squash Version:
- 1/2 cup (120 g) mayonnaise
- 1/4 cup (60 g) cooked butternut squash puree
- 1 tablespoon (15 ml) apple cider vinegar
- 1/2 teaspoon Dijon mustard
- 1/4 teaspoon salt
Instructions
- Classic No-Ketchup: In a small bowl, whisk together the mayonnaise, tomato paste, vinegar, sugar, garlic powder, onion powder, and smoked paprika (if using) until smooth. Add salt to taste. If the sauce is too thick, whisk in 1 tablespoon (15 ml) of water at a time until it reaches a drizzling consistency.
- Roasted Red Pepper: Place all ingredients in a blender or food processor. Blend on high for 30–60 seconds until completely smooth. If you don’t have a blender, finely mince the peppers and stir everything together.
- Butternut Squash: Whisk all ingredients in a bowl until smooth. If the squash puree is chunky, blend it first. This version is slightly sweeter and thicker than the others.
- For any version, taste and adjust seasonings—more vinegar for tang, more salt for savoriness, or a pinch of cayenne for heat.
- Cover and refrigerate for at least 30 minutes before serving to let the flavors meld. The sauce will thicken slightly as it chills.
Tips
- Substitutions: Use Greek yogurt or sour cream instead of mayonnaise for a lighter sauce (it will be tangier and less rich). For a vegan version, use vegan mayo and ensure the tomato paste is free of added fish sauce (most are).
- Storage: Store in an airtight jar in the fridge for up to 5 days. The flavors actually improve after a day. Stir well before using, as separation is normal.
- Common mistake: Adding too much tomato paste makes the sauce bitter and pasty. Start with 2 tablespoons (30 ml) and add more only if you want a stronger tomato flavor. Also, don’t skip the sugar—it balances the acidity of the vinegar and tomato paste.
- Make it smoky: A drop of liquid smoke (about 1/8 teaspoon) gives a barbecue-like depth without ketchup. Add it sparingly; it’s potent.
Serving Suggestions
Use this sauce on crispy french fries, sweet potato fries, tater tots, onion rings, or as a spread for burgers and sandwiches. It also works as a dip for roasted vegetables, chicken tenders, or even as a dressing for a hearty potato salad (thin with a little water or milk).
Variations
- Spicy Chipotle: Add 1–2 teaspoons of minced chipotle pepper in adobo sauce to the classic version. This adds heat and a deep, smoky flavor.
- Herby Green: Stir in 2 tablespoons of finely chopped fresh dill, parsley, or chives. This brightens the sauce and pairs well with fish and chips.
- Curry Ketchup-Free: Add 1 teaspoon of curry powder and a pinch of cayenne to the classic recipe. This gives an intriguing, warm spice that’s great with sweet potato fries.
- Honey Mustard Style: Replace the tomato paste with 2 tablespoons of Dijon mustard and add 1 tablespoon of honey. This is more of a honey mustard sauce, but it’s a delicious ketchup-free alternative.
Storage and Reheating
Store the sauce in a sealed container in the refrigerator for up to 5 days. Do not freeze, as the mayonnaise will separate and become watery. This sauce is served cold, so there is no reheating needed. If it has been refrigerated, let it sit at room temperature for 10 minutes before serving to soften. Stir vigorously to recombine any separated liquids.
Frequently Asked Questions
Can I use tomato sauce instead of tomato paste? Yes, but tomato sauce is thinner and less concentrated. Use 3–4 tablespoons (45–60 ml) of tomato sauce and reduce the water. The flavor will be milder, so you may need extra vinegar and salt.
My sauce is too tangy. How do I fix it? Add a pinch more sugar or a teaspoon of honey to balance the acidity. You can also stir in a little more mayonnaise to mellow it out.
Can I make this without any tomato product at all? Absolutely. The roasted red pepper version has no tomato paste. For a completely tomato-free, pale orange sauce, use the butternut squash version—it’s naturally sweet and creamy.
Is this sauce safe to take on a picnic? Yes, as long as you keep it cold. Perishable foods like mayonnaise-based sauces should not sit at room temperature for more than 2 hours (1 hour if it’s above 90°F/32°C). Use an ice pack in a cooler.
Can I use this as a salad dressing? Yes, thin it with 2–3 tablespoons of water or milk until it reaches a pourable consistency. It makes a great creamy dressing for potato, pasta, or coleslaw.
Why does my sauce taste bitter? Bitterness usually comes from too much tomato paste or over-processing the roasted red peppers (the seeds can turn bitter). Make sure to remove all seeds from the peppers, and use the exact amount of paste.
