How to Make Texas Roadhouse Cajun Horseradish Sauce

  • Horseradish Sauce: When making this sauce, it’s important that you use prepared horseradish and not horseradish sauce. Horseradish sauce is going to already have mayo or sour cream added to it so it won’t be very spicy.
  • Mix: Grab a medium-sized bowl and add the mayonnaise, sour cream, chili sauce, cayenne pepper, and horseradish sauce. Mix it all together with a spoon, spatula, or whisk.
  • Chill: Place your sauce in the fridge to chill for at least 2 hours and serve in your favorite serving bowls.

Can Cajun Horseradish Sauce be made ahead of time?

This sauce will last a couple of weeks in the fridge, so go ahead and make it ahead of when you need to serve it. It will make food prep that much easier if you are expecting company.

Variations on Texas Roadhouse Cajun Horseradish Sauce

  • Sweet: If you like a little sweet with your spicy, add some brown sugar to the mix.
  • Extra Seasonings: Add Cajun or Creole seasoning mix into the dip to give it even more flavor.
  • Spicy: If you are looking for a spicier version of this Cajun Horseradish Sauce, add more cayenne pepper or a few drops of your favorite hot sauce.

Key Ingredients

  • Chili Sauce: Similar to ketchup with added spices, surprisingly Chili Sauce doesn’t have any chili in it. Some recipes call for cayenne pepper but most are just tomato paste, brown sugar, vinegar, cinnamon, and allspice. It’s a mild sweet tomato sauce used in recipes like Cocktail Meatballs.
  • Prepared Horseradish: This is a pickled version of the grated horseradish root with vinegar and salt. It is not the same thing as horseradish sauce, which is creamy and mild. You can usually find prepared horseradish in the deli department and near pickled items or condiments.
  • Mayonnaise & Sour Cream: These two ingredients will add the creaminess to the dip. Sour cream will also bring a tangy flavor and mayonnaise will add a slight sweetness and richness.

  • Store: Store your sauce in a jar or an airtight container for up to 2 weeks in the refrigerator.
