Homemade Fry Sauce

If you walk into a restaurant in most states and ask for fry sauce, you are likely to get either a strange look, or a handful of ketchup packets. Trust me. I know from experience. And no, it’s not Thousand Island Dressing either. This fry sauce is so yummy and really easy to make, I can’t explain how just a few 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. Try it. You will love it. You will never go back to eating fries with plain old ketchup again.

This is just one of many delicious dips and sauces we love! Try dipping breadsticks in our homemade alfredo sauce, drench chicken with our yummy homemade barbeque sauce or serve fish and chips with this easy to make tartar sauce.

What is Fry Sauce?

For the most part, this tasty condiment can be 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 spoonsful of each in a bowl and whisk until you get a glorious pink color. However, as you’ll see when you read our recipe below, there are several ways to create this iconic dipping sauce. Once it’s made, 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.

Restaurant Variations

Now as you will see in the recipe below, there are all kinds of variations you can make to the original fry sauce. We have included three different variations including:

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.

In-n-Out Fry Sauce

This version has 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.

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 Tasty Fry Sauce Ideas

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.

  • Add a little pickle juice to the mayo and ketchup for an extra tangy flavor.
  • For a little kick, toss in a dash or two of hot sauce, cayenne pepper and paprika.
  • Add any spices you like to a basic ketchup and mayo mixture: garlic powder, salt, black pepper, onion powder or grill seasoning.
  • A teaspoon of Worcestershire sauce will give the fry sauce a deep flavor that tastes delicious on a burger.
  • Stir in a a splash of apple cider vinegar to the ketchup and mayo.

    1. My ex husband said the basic ingredients for the fry sauce is french salad dressing when you don’t have any, but i didn’t like it on lettuce

      1. Fry sauce is thicker, and to me tastes different. It’s not as tangy as French salad dressing – but, maybe that’s just me. In either case, the fry sauce is delicious on French fries!

    2. I have been making the basic fry sauce (though I didn’t have a name for it) for at least fifty years and spooning it over lettuce wedges. I’m a Texan, born and raised in Houston.

    3. Fry Sauce is nothing more than Mayo, Ketchup, & whatever else you choose to add into it – depending upon your palate, and on what you’ll be eating it with. IMO, add in whatever you desire. OMG, it’s NOT a recipe which is chiseled in stone, so go with your personal taste buds. It’s REALLY not a big deal for most of us.

    4. 5 stars
      I can not wait to try each and every one of these fry sauces! I can’t decide which one to try first as they all look and sound incredible!!
