This quick fry sauce blends creamy mayo, ketchup and a touch of tang for the classic Utah-style dip you’ve seen at burger joints. It’s smooth, zippy and perfect for French fries, burgers, onion rings and more.

What is Fry Sauce?
Turns out all the special sauce consists of is mayonnaise, ketchup and garlic powder. Real special. Well, turns out, most craveable fast food restaurants have the same mayo-ketchup base, but with a few extra ingredients.
Whopper sauce, In-n-Out Burger and Cali Burger all add minced dill pickles and a little bit of sweet and tangy with sugar and vinegar to their mix.

Gather This
Use simple ingredients to whip this versatile fry sauce, the perfect accessory to a plate of French fries. A full list of ingredients with measurements for this recipe is available in the printable recipe card below.
- Mayonnaise– this is the base of the sauce. Some folks that are adverse to mayonnaise can use a plain Greek yogurt, but make sure that it is Greek because it is thicker because it has been drained and thus more the same consistency as mayo.
- Ketchup– The other prime ingredient in the sauce, there isn’t much you can swap it out with, but if you want to try to make your own to control the sugar levels.
- Dill pickles (or relish)
- Yellow mustard
- Fine sea salt
- Ground black pepper
- Sugar
- Apple cider vinegar
- Scallions

You are going to love how easy it is to make this versatile sauce.
- Add ingredients to food processor. Place the mayo, ketchup, pickles, vinegar, mustard, pepper, sugar and salt to a small food processor or bowl.

- Use or chill. Serve immediately or cover and refrigerate.

Variations & Add Ins
You can mix up this fry sauce recipe in just about any way you’d like to. Here are a few suggestions.
- Spicy – Spice things up by adding a couple dashes or sriracha or your favorite hot sauce.
- Smoky – If you like a smoky flavor, try adding liquid smoke or a sprinkle of smoked paprika.
- Zesty – There is already some zest from the mustard, but add a little more by adding some apple cider vinegar.
- Pickle-forward – In addition to the pickles or relish, try adding a splash of pickle juice.
Other options include adding a dash of onion powder, garlic powder, Worcestershire sauce, cayenne pepper, jalapenos, bacon or a little bit of pickle juice or lemon juice.

What to Use it On
Clearly, just use the homemade fry sauce for dipping homemade french fries, but I also used it on my Copycat In-N-Out Burger Animal Style Fries. If you’ve never had them, you don’t even know what you are missing.
Use fry sauce for onions rings and Onion Strings, tater tots, chicken nuggets, sweet potato fries, potato wedges or slather it onto a burger, hot dog or chicken sandwich. Also great for dipping chicken wings!

I drowned my smash burger in this sauce and it was awesome! I had some extra and drizzled it all over my salad the next day! haha Thanks for sharing this!
This is unbelievable and we’ve been using it with so many things! Fries, chicken strips, breaded shrimp… it’s just so good!
I love dipping fries in mayonnaise so this sauce is a great easy variation without buying another bottle – perfect.
This was so easy to make and was delicious!
Hi, I would like to try this recipe, but we do not reside in the USA, so I would like to know if the yellow mustard would be the powder or the one you get in the restaurants to put over your fries? Kind regards

The one you get in a bottle for your fries 🙂 Let us know how it turns out!
FYI the whopper has only mayo and ketchup.
Thanks for that- I’ve honestly never had one 🙂
The ingredients sound a little weird, but surprisingly enough it’s delicious. I ate this on a hamburger. I haven’t tried this with BBQ sauce because I enjoyed the ketchup so much. Don’t think hubby would care for it… he’s not a big fan of Maya. Very quick and simple.
So glad you enjoyed it!
Your Fry Sauce was excellent and so very easy to make!!!!! We dipped our fries and put it on our cheeseburgers. Next time we have it will need to double the recipe! Thanks for sharing it with us.❤
Pam, that is lovely to hear and thank you for taking the time to stop by and let me know!
Thank you. This is fun.
