Learn how to make homemade ketchup without sugar. This homemade ketchup recipe is naturally sweetened with monk fruit, is low in calories and and has zero net carbs. It has a bold tomato flavor that goes perfectly with sandwiches or anywhere you need to use ketchup and is great option for diabetics or those on a keto diet.


Homemade Ketchup without Sugar


Have you read the label on store bought ketchup lately? Most brands have a lot of sugar and even preservatives. Many are also sweetened with high fructose corn syrup, which I actively try to avoid in my diet. Instead of going without this classic condiment, I decided I’d make my own homemade ketchup recipe.


Not only is this recipe for homemade ketchup sugar free and naturally sweetened, it is also low carb with fewer calories. In addition, you’ll find that it also has a fresher flavor than its store bought version as it uses fresh, natural ingredients. As a result, it is typically also higher in nutrient rich vitamins and minerals.


Is Homemade Ketchup Better?


If you’ve never had healthy homemade ketchup, then you’re in for a fun treat. Since this tomato ketchup recipe is made from real tomatoes and fresh spices, it has a bold, robust tomato flavor. You can also taste the spices in this sugar free ketchup recipe.


This no sugar homemade ketchup is also a healthy ketchup alternative. It is sweetened naturally with monk fruit, so it’s sweet without adding any calories or extra carbs. Additionally, unlike sugar, monk fruit won’t impact glucose levels. Therefore it’s a great alternative for those with diabetes as well.


How Long Does Homemade Ketchup Last?


This homemade ketchup recipe will last for about two to three weeks in the fridge. To help it last longer, sterilize the jar for 10 minutes in boiling water before putting the healthy homemade ketchup in the jar.


I would like to offer a word of caution if you plan on boiling the jar. Not all jars can be reheated or boiled. I’m all for reusing glass jars that came with other foods in them, but some glass is meant to be heated just once and can’t be reheated again. If you boil it, the glass could burst.


I recommend using canning jars if you plant to boil the jar for your homemade ketchup with fresh tomatoes. Canning jars are made for heating over and over again.


Can You Can This Sugar Free Tomato Ketchup?


No, I do not recommend canning this no sugar homemade ketchup. It makes a small batch of two cups of homemade ketchup, so it’s not enough to can anyway. This recipe hasn’t been tested for pH, and tomatoes are a borderline low acid food. The vinegar may not be enough to get the pH within the safe range.
