IS KETCHUP LOW CARB?
There are various reasons that you could be looking for sugar-free ketchup. Some people just want to reduce their sugar intake (which is great!), while others may be eating low carb or keto.
So, can you eat ketchup on a low carb diet? The answer is, it depends, but usually no.
Traditional store bought ketchup is not low carb or keto. It’s made with added sugar, or even worse, corn syrup. The nutrition info varies by brand, but it’s roughly 4 to 5 grams of sugar per tablespoon of ketchup. That may not sound like much, but it can really add up! And because it’s mostly simple, added sugar, it definitely spikes insulin.
There are some sugar-free ketchup brands, but most of them use artificial sweeteners, which I prefer to avoid.
Fortunately, there is still a way to enjoy ketchup on a low carb diet and avoid sugar. Just use my sugar-free ketchup recipe instead! It has only 1 gram of sugar per serving, which comes only from the tomatoes.
THE KEY TO LOW CARB KETCHUP OR KETO KETCHUP
The key to making low carb ketchup or keto ketchup is really just the sweetener. Instead of sugar, or syrup, we use powdered monk fruit or powdered erythritol.
Why powdered and not granulated? Because this ensures that the ketchup is smooth, and not grainy.
You can also use a concentrated liquid sweetener if you prefer. Liquid monk fruit extract is my favorite. Otherwise, you can also make this sugar-free ketchup with stevia. Make sure it’s the liquid or concentrated powdered form, not a granulated blend.
INGREDIENTS FOR A SUGAR-FREE KETCHUP RECIPE
To figure out the ingredients for a homemade sugar-free ketchup recipe, I simply looked at the bottles of several popular brands of regular ketchup.
Of course they didn’t specify amounts, and some of the listings for spices were nondescript. But, it was a good starting point.
Here are the ingredients I ended up with in my low carb ketchup recipe:
- Tomato paste
- Powdered sweetener (see notes about sweeteners above!)
- White vinegar (or use apple cider vinegar for paleo)
- Sea salt
- Onion powder
- Garlic powder
- Ground cloves
- Mustard powder
HOW TO MAKE SUGAR-FREE KETCHUP FROM SCRATCH
The process for how to make sugar-free ketchup is super simple! It’s actually somewhat similar to my favorite low carb sugar-free BBQ sauce.
Start by whisking all the ingredients together in a small saucepan. Then, simmer over low heat for about 30 minutes. The mixture will reduce, meaning some of the water evaporates, the flavors will combine, and the sugar-free ketchup will thicken.
The amount of time needed for the keto ketchup to reduce and thicken will vary widely. It will depend on the size of your pan and the temperature of your stove. Just continue simmering gently, stirring occasionally, until it’s as thick as you want it.
Finally, puree the sugar-free ketchup in a blender. (A high-power blender works best.) This step is not required, but I highly recommend it for the smoothest texture that is most similar to the ketchup you’re probably used to.
HOW TO STORE HOMEMADE SUGAR-FREE KETCHUP
Homemade sugar-free ketchup stores very well in the fridge. It will keep for at least a week, maybe even longer. The vinegar really helps to preserve it.
Sometimes, this low carb ketchup can separate a bit if it sits for a while. Give it a stir and it will return to normal.
