If you don’t know what Fry Sauce is, you are missing out! Just mix a few simple ingredients and you will never dip your fries in anything else again!

Not too long ago, if you’d walk into a restaurant in most states and ask for fry sauce, you would likely get either a strange look or a handful of ketchup packets. Trust me. I know from experience. Thankfully that’s not the case anymore! The secret is out! This irresistibly creamy sauce is the belle of the french fry ball, and has won over tastebuds throughout the nation with its charming deliciousness. Seriously, this fry sauce is so yummy and super easy to make! I can’t explain how just a couple simple ingredients can take the potato world by storm, but they have and they do. I grew up on this stuff. To be honest, it’s probably the first “recipe” I ever made when I was 4 or 5. Try it. You will love it. You will never go back to eating fries with plain old ketchup again.

What is Fry Sauce?

Originally, this tasty condiment was mainly found in Utah, Idaho, and parts of Oregon. At its most basic level, a fry sauce recipe is just a combination of ketchup and mayonnaise. Put a couple of spoonfuls of each in a bowl and whisk until you get an orange-y pink color. Once you have the basics down, the options for what to dip into it are endless. Make sure to store it in the fridge, and the batch will last up to a week.

Ingredients to make Fry Sauce including ketchup and mayonnaise.

Fry Sauce Ingredients

Fry sauce is made of 2 ingredients: Ketchup and Mayonnaise. Pretty simple, right? There is no need to overcomplicate it. In my opinion, it is very best with Best Foods Mayo (Hellmann’s for you East coasters) and Heinz Ketchup. Combine 1 part ketchup to 2 parts mayo (1:2 ratio) and stir well. That’s it!

Restaurant Variations

As you will see in the recipe below, there are all kinds of variations you can make to the original fry sauce. Here are some of our favorites

Red Robin Campfire Sauce: BBQ sauce replaces ketchup in Red Robin’s Campfire Sauce. It tastes great with onion rings, fries, and chicken strips or nuggets. This is a sweet and savory sauce that is a delicious dip to go with a variety of recipes. The perfect combination for thick fries!

In-N-Out Fry Sauce: This version has a pickle relish in it. The relish gives it more of a dill flavor and the little chunks of pickles give it some texture and crunch. Mix together in a small bowl and get ready for loads of flavor!

Outback Steakhouse Blooming Onion Sauce: A little horseradish and brown mustard give this fry sauce some kick. It gives onion rings and French fries a richer, more mature taste.

More Additions and Variations

You can mix and match or substitute the flavors above or come up with your own. They are all the same basic idea and they are ALL so tasty in their own way. Here are a few additional ideas to try:

  • Mustard: Yellow mustard is the most popular addition for most fry sauce recipes. It adds a new dimension of flavor that I absolutely love. Just a little squirt of mustard is all you need to take your fry sauce to the next level.
  • Pickle Relish: Add a little pickle relish or juice (dill or sweet) to the mayo and ketchup for an extra tangy flavor.
  • Hot sauce: For a little kick, toss in a dash or two of hot sauce, cayenne pepper and paprika.
  • Spices: Add any spices you like to a basic ketchup and mayo mixture: garlic powder, salt, black pepper, onion powder, or grill seasoning.
  • Worcestershire: A teaspoon of Worcestershire sauce will give the fry sauce a deep flavor that tastes delicious on a burger.

    In and out sauce is the go to, and not just for fries! I make it with my homemade zucchini relish
    Also great with Mozzarella stix, and veggies!

  2. 5 stars
    I’m an Idaho girl, and we take our potatoes seriously around here! Fry sauce is the best way to enjoy our homegrown spuds! This recipe is perfect to get the right ratios, and I love all the variations you listed to mix things up. Once you dip with fry sauce, it’s the only condiment you will want to use!

  3. 5 stars
    Love this as a base- added smoked paprika and few dashes of cholula. Served with oven fries. It was gobbled up!

  4. 5 stars
    I would give this recipe 5 stars! It’s so versatile. My mom made a version of this when I was growing up – it was the only dip we had and we loved it! Thanks for the variations – I will try them with my family.
