Seafood Dipping Sauce
Spicy Mustard Seafood Sauce Recipe – A 5-ingredient Seafood Dipping Sauce for crab legs and shrimp. Plus, it’s gluten free, dairy free, and ketogenic!
Seafood Dipping Sauce for Crab Legs and Shrimp
Do you eat more seafood in the summer than at any other time of year? We do.
Many types of fish and shellfish are so plentiful in the summer that it seems fitting to strap on a plastic bib and pull out the shell crackers.
Not to mention that summertime is the best time to head out towards the beach for vacation. This crab mustard sauce recipe will be your saving grace when making fresh seafood from home (or your vacation rental!)
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.
Seafood Mustard Sauce Recipe
Today’s 5-ingredient Spicy Mustard Seafood Sauce recipe is my absolute new favorite seafood dipping sauce for fresh-caught Dungeness crab and local Carolina shrimp. Yes, we have a popular cocktail sauce recipe that can be used for dunking. However, if you are looking for something unique, this is the seafood sauce for you!
It’s light and perky with a mellow base of gluten-free mayonnaise, a strong tangy note, 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!

I used S&B oriental mustard powder instant of prepared mustard or horseradish. That S&B stuff is HOT, like Chinese restaurant hot, like wasabi hot!!!! Mixed with water to make a paste, added mayo, lemon juice, hot sauce, and black pepper. It was still super hot so mellowed it out with sweet relish and rose wine balsamic. That toned it down a lot. Served with steamed shrimp and oysters on the half shell. Everyone loved it but agreed a little goes a long way. We were thinking it might be really good putting that on good-quality hot dogs with some sauerkraut. Labor Day is coming up! Thanks for the inspiration!
I have enough left over I’m thinking of making a potato salad with it. Maybe add some seafood to it also. It also would be great to mix in for deviled eggs or as a sandwich spread. I’m feeling my Labor Day taking shape. Again, THANKS!
This is absolutely the best mustard sauce I’ve ever made! You can put this on a car bumper and it’d be delicious! I use Dijon instead of yellow mustard cuz I like the heat but the shallot is what makes this IMO.
Glad you didn’t say flip-flop. HeHe.
That spicy mustard is so good on seafood! It gives it a nice flavor!
I made this sauce with our shrimp last night and it was incredible! Definitely our new go to condiment!
I’ve been doing this sauce for years, but I add fresh garlic and little honey ?
these are some great meals for the beach
Thank you for such a great recipe. My husband’s family tradition is fondu on Christmas Eve. We have wanted a non sweet mustard sauce for dipping. This was it! Balanced and wonderful. It will be used in our family on Christmas Eve every year!
