This sugar free ketchup is sweet, tangy, and tastes so good, you won’t miss the sugar! Keto friendly, low in carbs, and using just 3 ingredients. 

sugar free ketchup.

We take our condiments seriously in our house and always have at least one or two on the table for every meal. So, when I’m watching my sugar intake, you better believe I’m making sugar free BBQ sauce, sugar free honey mustard, and sugar free ketchup.  

Mainstream brands pack their sauces with copious amounts of sugar and, worse–high fructose corn syrup. Luckily, this sugar-free version tastes just as good as store-bought ketchup but with a fraction of the carbs and calories.

Why I love this recipe

  • Easy to make. If you ever thought making your favorite sauces and condiments from scratch was hard, this recipe will convince you otherwise. 
  • Simple ingredients. There are no hard-to-pronounce ingredients or additives in this recipe. Just kitchen staples and a little sugar substitute. 
  • Guilt-free. At 8 calories and 1 gram of net carbs per serving, this is a game changer for those of us on a low carb diet or trying to cut back on added sugar.
  • It goes with anything. From air fryer french fries to healthy burgers and keto chicken nuggets, you can use this ketchup exactly as you would regular ketchup.

Ingredients you’ll need

  • Tomato paste. Not tomato sauce or passata! Tomato paste is super concentrated and gives plenty of tomato flavor, with no tomatoes needed.
  • White vinegar. I used a combination of apple cider and white vinegar, so the apple flavor would not be overpowering. 
  • Sweetener of choice. Either keto brown sugar or powdered sugar substitutes. I prefer the former, as it gives the ketchup a more authentic flavor, but any store-bought or homemade sugar-free sweetener will work.
  • Onion and garlic powder. A little of both for added flavor. Do not use onion salt and garlic salt, or the ketchup will be too salty! 
  • Water. To thin out the mixture and the ketchup.

Step 1- Simmer: Start by mixing all your ingredients in a small saucepan. On medium heat, heat the mixture until it simmers. Once it has simmered, reduce to very low heat and stir regularly, for 10 minutes. 

Step 2- Chill: Remove from the heat and let cool completely, to thicken.

Recipe tips and variations

  • Be sure to taste-test the ketchup while you are stirring it up. If it is too thick, you can add more water to thin it out. Also, if you prefer sweeter ketchup, add extra sweetener.  
  • Do not use stevia or stevia blends of sugar. They are renowned for having a bitter flavor. 
  • Add other spices or herbs like oregano, cayenne pepper, or even red pepper flakes.
  • Store in a squeezable bottle, for the same convenience as store-bought ketchup.

How to store leftovers

To store: Leftover ketchup must always be stored in the refrigerator since it doesn’t contain added preservatives to keep it safe at room temperature. If kept in an airtight container, it’ll stay good for up to 1 month. 
To freeze: Place the ketchup in a freezer-friendly container and store it in the freezer for up to 2 months. Thaw overnight in the refrigerator and give it a mix before enjoying it.

    The flavor is great, I like it better than store bought.
    I didn’t have the brown sugar substitute, so I used white sugar substitute.

  2. Love the simplicity here. I replaced all refined ingredients with ‘el fresco’: ‘brown sugar substitute’ replaced by 1 heaping tablespoon smoked real maple sugar from Quebec🍁, all apple cider vinegar (no white), fresh pressed garlic.

  3. 5 stars
    Fabulous! I used Xylitol as the sweetener. Tastes like and has the texture of regular ketchup. Used it to make my famous baked bean recipe, and everyone thought it was the best ever. No one knew it was low carb. Glad I made a triple batch!

  4. 5 stars
    This is GREAT recipe. I did add 1/2 t paprika (to make the ketchup a bit darker) and 1/8 t of ground cloves. Husband loves this ketchup. So easy and so much better than commercial.

  5. Delicious replacement for ketchup, my husband won’t eat any other now. This weekend I made shrimp cocktail using it ! So good,everyone loved it 😊

    Great ketchup recipe. The advice to use keto brown sugar is best. Simple to make and will become a base for several sauces. Thank you for sharing!!

    Best ketchup I’ve ever tasted! I don’t see myself buying store bought ketchup ever again! Thank you for sharing this recipe with the world!! ❤

    I made this as described. It was an excellent replacement for the sugar filled tomato sauce from a bottle that I would normally use (I am an Aussie so we tend to call the bottled stuff sauce rather than ketchup).

    Was easy to make and will be on my must have recipe list! Good job!

    Cheers,
    Michael

    1. Cheers, Michael- Fellow Aussie here, I call it sauce too personally, but had to call it ketchup for the majority haha!)
