Fish and seafood just begs for creamy and tangy tartar sauce. But most bottled tartar sauces are chock full of preservatives and questionable ingredients. This easy keto tartar sauce recipe will help you make it at home in less than 10 minutes. Enjoy it with my keto crab cakes for an easy main dish!

What is tartar sauce?
Tartar sauce is a mayonnaise-based sauce that you typically serve with seafood such as crab cakes, salmon, fish and chips, and so on.
You can often get tartar sauce at your local grocery store near the seafood or condiment sections. But, for a better flavor that is easy to make at home, which is why I’m sharing my homemade keto tartar sauce recipe.
Ingredients in Tartar Sauce

- Mayonnaise: If you are following a low carb or keto diet, you want to look for full-fat mayo. Fat-free, reduced-fat, or mayo dressings often contain added sugars to help offset flavor lost from the removal of fat.
- Dill Pickles: You can chop these to mimic the size of relish. Larger chunks will result in more bite.
How to Make Tartar Sauce

To make homemade tartar sauce, measure the ingredients and add them all into a small bowl (photo 1).
When they are all in the bowl, mix the ingredients together (photo 2).
Top Recipe Tips & FAQs
- Let the tartar sauce sit for 15 to 20 minutes to allow the flavors to come together.
- Spice it up with horseradish add a 1/2 teaspoon at a time since a little goes a long way and things can get too spicy quick!
Bottled versions of tartar sauce are usually low-carb, but not necessarily keto because it contains added sugar, preservatives and other stuff to stabilize it’s shelf life. If you are following strict keto, Whole30, or paleo, homemade versions are better options.
If you are following a Whole30 or paleo diet, you will need to substitute the mayo from the one I suggested. Here are some vegan mayo options.
If you plan on storing homemade keto tartar sauce, keep in mind, the recipe does not call for any preservatives. In the refrigerator, the homemade sauce will last 2 to 3 days in a sealed container. I prefer to use a glass jar to store the tartar sauce in. And, to save a bowl from being washed, I will often make the tartar sauce in the same jar.
