Is ketchup keto-friendly?
Your typical ketchup, also known as Tomato Sauce in the Commonwealth, is not at all keto-friendly.
And no, this is not solely because of the tomatoes. Store-bought ketchup is so high in carbs because it has added sugar. Check out the food label above. Sugar is the second ingredient!
Tomato is a low-carb vegetable with 2.6g of net carbs per 100g. So let’s see below how we can turn this low-carb vegetable into keto-friendly ketchup!

- Tomato puree, or fresh tomatoes.
- Tomato Paste made with only tomatoes.
- Onions for the taste. Yes, onions are also a low-carb vegetable. Not the lowest, but since we’re not using too many of them, it’s fine!
- Erythritol to replace the sugar added in classic ketchup recipes. You could pick another keto-friendly sweetener. Make sure to read my sweetener guide to make the best choice!
- Apple Cider Vinegar to add the typical bitter ketchup taste.
- Ground Paprika
- Extra Virgin Olive Oil
I took my inspiration from Sugar-free Mom’s Ketchup recipe. Her sugar-free ketchup recipe is quite different as she is using honey, so it isn’t keto-friendly.
If you are not particularly low-carb and want to try honey in my recipe, I would recommend using 4 tablespoons of honey instead of the 2 tablespoons of erythritol and then adjusting to taste.
How to make sugar-free keto ketchup
Making the recipe is very easy. It only takes a few steps!
Prepare the low-carb vegetables
Chopped your onions and the garlic cloves into small bits.
Fry the onions in a saucepan with olive oil, and add the garlic and paprika.
Add the tomato paste
Once the onions are coated in paprika, add your tomato paste. Make sure it does not contain any added sugar!
Let it simmer for a couple of minutes, and then add the tomato puree, also known as tomato passata.
For a sweet taste, add a sugar-free sweetener like Erythritol. Let it simmer for a few more minutes over low heat.
Blend the ketchup
Once your sauce has thickened, use an immersion blender to turn it into smooth ketchup.
The color of the ketchup is slightly lighter than the store-bought version, but the taste is very similar. This is a very simple ketchup recipe that makes about 300g of ketchup.
