Keto Cocktail Sauce

It’s easy to make low carb keto cocktail sauce! Simply replace the sugary ketchup with unsweetened ketchup. It tastes just like the restaurant version!

I’ve been wanting to make low carb keto cocktail sauce for a long time now. I don’t know why it took me so long – it’s so very easy to make.

Can you eat shrimp cocktail on keto?

Yes! You just need to make a low-sugar sauce. To make it, you can use any recipe you like. Simply replace the regular, sugary ketchup with unsweetened ketchup.

I like to use this brand, that I buy at Whole Foods, and is also available on Amazon.

If you look at the ingredients list you’ll see that it’s not perfect. It contains maltodextrin, the all-mysterious “spice,” and “natural flavor,” all of them fairly questionable ingredients.

But it is very low in carbs, and a good compromise to use once in a while when I serve boiled shrimp as an appetizer (or have a big plate of them for my lunch) and want a keto cocktail sauce for dipping.

The ingredients needed for this recipe

You’ll only need a few ingredients to make this easy recipe (the exact measurements are in the recipe card below):

  1. Unsweetened ketchup
  2. Horseradish
  3. Worcestershire sauce
  4. Hot pepper sauce

How to make keto cocktail sauce

It’s so easy, I can hardly call it a recipe! Here are the steps:

  1. In a small bowl, whisk together the ingredients.
  2. Cover and chill until ready to use.
  3. Mix again before serving.

Drawn butter is another keto option

Shrimp cocktail is one of my favorite appetizers to order in restaurants (another favorite is deviled eggs).

I realize that the sauce served in restaurants is high in sugar, so sometimes I ask them to serve the shrimp with melted butter. It’s delicious!

But I like cocktail sauce so much, that sometimes I figure the little I use with the six prawns they typically give you won’t be so bad. So I go ahead and order it.

Why is there so much sugar in regular ketchup?

This sauce tastes amazing. It basically tastes just like the restaurant version. It makes me wonder, why do they add so much sugar to regular ketchup? It’s completely unnecessary.

The only difference I notice is that I don’t like lemon juice in this recipe, so I omit it. Perhaps this is because there isn’t enough sugar in the ketchup to balance out the acidity.

How much horseradish should I add to keto cocktail sauce?

The brand of prepared horseradish I use is quite potent, so I only use one tablespoon of it.

Depending on the brand you use, you might need to add up to two tablespoons. It’s best to start with less, then taste and decide for yourself.

If you’re like me and really like shrimp cocktail, you can now enjoy it freely, even on a low carb or a keto diet! Here’s the recipe.

How long will it keep?

You can keep it in the fridge, in an airtight container, for up to 5 days. Give it another good stir before using it.
