What Is Popeyes Mardi Gras Mustard?

Not to be confused with honey mustard or hot sauce, Mardi Gras mustard is a cunning hybrid—an irresistible blend of sweet and savory, spicy and smooth. Thrillist named it one of the top 10 fast food dipping sauces, writing: “It looks like a regular honey mustard, but tastes like a horseradish-filled take on the classic, with pleasant mustard notes in the finish.” The sauce is the perfect pairing for Popeyes’ menu, which features Southern comfort food favorites like fried chicken, biscuits and Cajun-spiced sides.

Unfortuntely for mega fans, it seems that the restaurant has discontinued the beloved sauce, at least at some locations. The good news is that it’s easy to make a super similar sauce at home with our Mardi Gras mustard copycat recipe.

How to Make Popeyes Mardi Gras Mustard


  • 1/2 cup mayonnaise
  • 3 tablespoons Creole mustard
  • 2 teaspoons prepared horseradish
  • 1 teaspoon brown sugar
  • 1/2 teaspoon garlic powder
  • 1/8 teaspoon cayenne pepper
  • Dash paprika


Step 1: Mix

In a small bowl, combine all the ingredients. Stir until well mixed. We like to use a fork or whisk to thoroughly mix in the spices.

Step 2: Chill

Cover the bowl and refrigerate. The flavors will develop over an hour or two.

Step 3: Eat

After a chill, the sauce is ready to enjoy. Slather a generous amount on your favorite chicken sandwich, or serve as a dipping sauce with breaded chicken cutlets, fries or pretzels. It’s also delicious on most cold or hot sandwiches, especially with ham.
