What Is Creamy Mustard Sauce?
Creamy mustard sauce is a smooth blend of mustard and mayonnaise, often balanced with a sweetener and acid for depth.
This version leans slightly sweet thanks to brown sugar, with apple cider vinegar adding brightness. The result is a well-rounded Dijon dipping sauce that complements salty meats and fried appetizers.
Unlike traditional Dijon cream sauce, this recipe does not use heavy cream. The mayonnaise provides richness while keeping the sauce thick and stable.
Ingredients (& What They Do)
1/4 cup Dijon mustard – Provides sharp, tangy flavor and depth.
1/4 cup mayonnaise – Adds creaminess and balances the mustard’s bite.
3 tablespoons brown sugar – Brings warmth and sweetness to offset acidity.
2 teaspoons apple cider vinegar – Brightens the sauce and enhances contrast.
Salt and pepper, to taste – Sharpens flavor and balances sweetness.
How to Make Creamy Mustard Sauce

Recipe Tips
