Best Secret Sauce For Burgers And Fries

The best thing about eating fast food is the secret sauce, in my opinion. The favorite fast food joint in my area is In-n-Out. While I personally am not a fan (don’t come after me 😆) one thing I do love is the In-n-Out burger and fry sauce.

Now I just make my own secret sauce at home to go along with my favorite frozen French fries. This recipe makes a large batch for all of your secret sauce needs. Feel free to halve the recipe if you only need it for one meal.

What Does Fry Sauce Taste Like

Secret Sauce is a creamy, tangy, slightly sweet dip. This version uses chili powder which brings just a touch of heat.

Some secret sauce recipes have onions or relish in them. I prefer the smooth, creamy, lump-free style. But go ahead and add onions and relish if you prefer.

  1. Maybe this is obvious to everyone but me, but I have to ask: is the pickle juice sweet or dill???

    1. Dill, I should add that clarification to the recipe 🙂
