What is Popeyes Mardi Gras Mustard?
Mardi Gras Mustard is a Cajun-inspired sauce that is served at Popeye's Louisiana Kitchen. It is often used as a signature dipping sauce for their famous chicken tenders or as a spread for chicken sandwiches.
It's a creamy and tangy blend of flavors, with a hint of heat from the Cajun spices.
The sauce's name is a nod to the festive and vibrant New Orleans celebration of Mardi Gras. It nails the bold and tasty flavors that make Louisiana's food so famous!
Key ingredients
Using a combo of easy ingredients, this recipe for homemade Mardi Gras mustard is the perfect copycat of the original.
Here's why these ingredients are important...
Whole Grain Mustard: To make the perfect copycat version of Popeyes Mardi Gras mustard, you need to use the right mustard. Now, there are so many types of mustard, but whole-grain mustard works the best! It has a coarse texture and adds a unique tangy flavor to the sauce.
Horseradish Sauce: I know it's a bit random, but it's a key ingredient in this homemade mustard recipe! Horseradish adds a little zesty kick to the sauce and pairs perfectly with the whole-grain mustard.
Brown Sugar: To balance out the tanginess of the mustard and horseradish, I like to add a teaspoon of brown sugar for sweetness. It doesn't make the sauce overly sweet, but just enough to round out all the flavors. Use my tips to make sure your brown sugar doesn't go bad.
Heather's helpful hints
If you can't find Cajun seasoning, creole seasoning could be a great substitute!
Cajun seasoning usually packs more heat because it has a bigger kick of cayenne pepper. Creole seasoning, while still tasty, is generally a bit milder on the heat scale. It's really up to you!
You can grab some whole-grain mustard from the store, or if you're feeling adventurous, try making it at home with this recipe.

Meal ideas
Whenever I order Popeye's chicken, I always make sure to get a side of Mardi Gras mustard. It goes perfectly with their crispy fried chicken tenders and brings a little something extra to the meal. But don't limit yourself there!
Here are some other ways you can use this delicious homemade sauce:
- Use it as a dipping sauce for seasoned fries or roasted veggies. The tanginess of the mustard pairs well with the saltiness of fries or the sweetness of roasted veggies.
- Spread it on a sandwich for an extra layer of flavor. It goes great with deli meat, grilled chicken, or even as a condiment for burgers and hot dogs.
- Mix it into your deviled egg filling for a twist on the classic dish. The horseradish and mustard add a unique flavor that will make your deviled eggs stand out.
- Use it as a marinade for chicken, pork, or seafood before grilling. The mustard's acidity helps tenderize the meat while also adding flavor.
- Thin it out with a bit of olive oil and use it as a salad dressing. It's perfect for a tangy, creamy dressing on a Caesar or mixed greens salad. It'd be great mixed with ranch dressing for a combo flavor!
