This Louisiana-style remoulade sauce is creamy, tangy, and packed with bold Cajun flavor. Mix it up in 5 minutes, let it chill, and you have a restaurant-quality dipping sauce that's perfect for seafood, fried foods, and sandwiches.
Combine all ingredients in a medium bowl and stir well until fully incorporated.
Cover tightly and refrigerate for at least 2 hours, or overnight for best flavor.
Taste before serving and adjust seasoning as needed. Garnish with chopped green onions if desired.
Notes
Mayo quality matters. This sauce is mostly mayo, so use the best you have. Duke's is a great choice. Avoid fat-free or light mayo.
Don't skip the chill time. The sauce tastes flat right after mixing. Two hours is the minimum; overnight is best.
Use fresh lemon juice for the best flavor.
To reduce heat: Swap spicy brown mustard for stone ground or whole grain mustard, or omit the hot sauce.
Horseradish substitute: Leave it out or replace with a small amount of extra mustard. The sauce will be slightly milder.
Cajun seasoning: This recipe was developed using my homemade Cajun seasoning, but any store-bought blend works. Taste and adjust after chilling since salt and heat levels vary by brand.
Storage: Keep refrigerated in an airtight container for up to 1 week.
Freezing: Not recommended. The mayo base will separate once frozen.
