Spicy Mustard Seafood Sauce Recipe – A 5-ingredients dipping sauce for crab legs and shrimp. Plus, it’s gluten free, dairy free, and ketogenic!
Do you eat more seafood in the summer than any other time of year? We do.
Many types of fish and shellfish are so plentiful in the summer months, it just seems right to strap on a plastic bib and pull out the shell crackers.
We love to steam or grill seafood in the warm season, then serve it with melted butter or creamy sauces.
However, this year I’ve been experimenting with dairy-free seafood dipping options, because our daughter is currently dealing with several food intolerances.
I want her to feel excited about her meals, even though she can no longer consume all the foods the rest of us can eat. Therefore, I’m skipping the classic standbys loaded with dairy and gluten, and using cleaner ingredients with bold flavor.
Today’s 5-ingredient Spicy Mustard Seafood Sauce recipe is my absolute new favorite dipping sauce for fresh-caught Dungeness crab and local Carolina shrimp.
It’s light and perky with a mellow base of gluten free mayonnaise, a strong tangy note from French’s® Classic Yellow Mustard, and a pop of spicy heat from onions and horseradish.
It’s got a kick, yet does not overpower the fresh sweet flavor of the seafood. Perfection!
French’s Classic Yellow Mustard is a summertime staple because it is packed with zesty appeal, and provides a gorgeous sunshine yellow color to recipes.
Yet, did you know it’s also very easy to incorporate into allergy-friendly foods?
Made with only mustard seeds, vinegar, water, and spices, French’s Classic Yellow Mustard is naturally gluten free, dairy free, soy free, nut free, and free of artificial colors and preservatives. Plus, it’s low carb keto fans!
It makes this Spicy Mustard Seafood Sauce a lean, yet tantalizing, addition to all your protein-packed seafood dishes.
