When we moved there from Kansas to Idaho, we would go to a fast foods place and they would ask us if we would like some fry sauce for our French fries. We didn’t have a clue what it was but we found out fast and it was delicious. You don’t need to use it just for fries either. You can put it on hamburgers too.
Homemade Fry Sauce
1 cup mayonnaise
1/2 cup ketchup
To taste; garlic salt, salt, Worcestershire sauce
Buttermilk or half and half* (optional)
Mix it all together. *If too thick, use the buttermilk or half and half to thin.

This recipe has been around for a long time! If you add some lemon juice to it, it is called Marie Rose sauce, which is usually served with fried fish. They also make this sauce in Belgian fry shops. :-]
Wow, I use to combine ketchup and mayo together, put in some chopped sweet pickles to use as a dressing resembling thousand island.
This might be similar to the sauce that Outback serves with their blooming onion. I’ve never heard of fry sauce but it looks good.
YUM! I’m going to make this tonight.
You forgot the pickle juice! lol
I made this sauce last night along with homemade french fries and was very good!
This is awesome
My dad and I both love fry sauce. He makes his own now, and in addition to what you have here, he adds a little bit of sweet pickle relish. I’m going to send him this link. He’ll really enjoy this

Yes admittedly we love our fry sauce. I make it a lot at our house.
I found out about Fry sauce when I moved to Utah. Oh I loveeeeee it!
Haha! I’ve been making my own fry sauce for years and I didn’t even know it. I just thought it was my own strange combination. It really is delicious.
Never been asked if I want this in a restaurant. Sounds like Chik Fil a’s Chik fil a sauce. my daughter told me about it and once I tried it, I loved it.
I think it depends on what part of the country you are from. We had never even heard of it in Kansas or Colorado but was asked if we wanted when we lived in the northwest.
Thank you for the recipe. I hadn’t thought to thin the sauce but will do so in the future. The most outstanding fry sauce I have found is a combination of cocktail sauce and tartar sauce! Sprinkle the fries with malt vinegar and dip them in the sauce.
