Keto Ketchup Recipe

Ketchup is King of the Condiments.

Unfortunately, you can’t really find a low carb version of it out there anywhere. So people on Keto are just SOL.

Since Rebecca likes it on her eggs and I like it on everything else, we decided to get in the kitchen and start tinkering with recipes.

After some trial runs and testing out different ingredients, we’ve landed on a Keto Ketchup that we really like. I really just took an old Ketchup recipe that I developed years ago and retooled it. My old recipe had brown sugar in it, so that wouldn’t do for Keto.

The good thing about converting this recipe to Keto is that I used my original in a number of different BBQ Sauce recipes. I’m looking forward to using this as a base for some new Keto Sauce recipes to post for you later…. and also so I can use the sauce on the grill! I’m not not completely altruistic, afterall.

Hopefully, you will enjoy it too.

It’s really easy to put this together and I only have a couple minor recipe notes for you on this on

Recipe Notes

The Sweetener

We tried a few different sweeteners with this Ketchup Recipe and ultimately landed on confectioners Monk Fruit.

  • Erythritol gave the ketchup an unpleasant, tinny aftertaste.
  • Golden Monk Fruit, which I tried because it’s so much like brown sugar, left a few granules in the finished ketchup. While it tastes great, there’s a slight texture issue. Even after it sets for a while, it doesn’t fully dissolve; though it IS much less noticeable after sitting overnight. If this is all you have, it’ll work.
  • Confectioners Monk Fruit: This provided the perfect amount of sweetness and texture. It also didn’t require any cooking, so everything can be mixed together cold and you still end up with a very smooth texture in your final product.

Confectioners Monkfruit:

Monkfruit is a wonderful, Keto-approved sweetener. Since we discovered it, we’ve started using it in everything that needs sweetness.

Monkfruit sweetener stands up well to the heat of baking, it tastes great and doesn’t have a bad aftertaste. It has no carbs, and actually contains a substance that is reported to help stabilize blood glucose levels.

Amazon is the most reasonably priced and convenient place we've found to purchase it.

We put together a handy chart of 55 sweeteners commonly used on the market today. The chart shows you which sweeteners are actually sugar, which ones are bad chemicals or natural, where they land on the Glycemic Index and more.

We also rank each sweetener on the list as Good, Bad, or Ugly for Keto.

Tomato Paste

We looked all over the place for a lower carb tomato paste. I just don’t think such a thing exists. We also weighed the possibility of making our own. That’s such a long process, though, we didn’t feel like it was worth it.

The plain old Huntz 6oz cans of tomato paste did the trick for us in this recipe. You can easily find those in any grocery store.
