Mardi Gras mustard sauce brings amazing flavor and a touch of New Orleans to any dish. I remember when I first tried it, I wanted to use it on all of my food.

Unfortunately, some Popeye’s discontinued their popular Mardi Gras mustard sauce so naturally I had to try making my own. This copycat version comes so close to the restaurant version and adds a wonderful, zesty kick to everything from chicken to vegetables.

What makes this Mardi Gras Mustard stand out?

  • Sweet and spicy – You can’t beat the flavor fusion of this incredible sauce recipe.
  • Great copycat – When you can’t get the sauce at the restaurant anymore, this is the perfect substitute.
  • Versatility – Can be served with so many types of food as a dip, sauce, or dressing.

Ingredients needed for Mardi Gras sauce

This easy copycat recipe needs just a few ingredients to taste so close to the restaurant favorite.

  • Mayonnaise – Use your favorite mayonnaise.
  • Creole mustard – If you can’t find prepackaged creole mustard you can make your own homemade creole mustard.
  • Prepared horseradish – This adds a little bit of spicy heat to the sauce. It can usually be found in the condiments aisle of the grocery store.
  • Brown sugar – A little sweetness to balance out the spice. I am using light brown sugar but you could use dark brown sugar.
  • Garlic powder
  • Paprika
  • Creole seasoning – You can typically find a Creole seasoning or Cajun seasoning blend in the spice aisle.

How to make copycat Popeye’s Mardi Gras mustard sauce

Step one: Place the mayonnaise, creole mustard, horseradish, and seasonings in a small bowl. Stir to fully combine. Cover the bowl and let chill in the refrigerator to let the flavors blend together and develop. I like to let it sit for at least an hour.

Recipe tips and substitutions

Mustard – If you have a hard time finding creole mustard and don’t want to make your own, you can substitute with 1 tablespoon of whole grain mustard plus 1 tablespoon of spicy brown mustard.

Heat – If you like your mustard sauce extra spicy, add a little extra horseradish or a splash of hot sauce.

Chill time – I recommend letting the sauce chill for at least an hour to really maximize on the flavors developing.

Store – Keep the sauce in an airtight container in the refrigerator for up to a week.
