The biggest and best reason to make tomato ketchup at home is so you can control the ingredients. There are no preservatives, added “flavors,” and no sugar or high fructose corn syrup, which is common in most bottle ketchups you can find at the grocery store. Even some homemade ketchup recipes call for a ton of sugar!

Most bottled and store-bought ketchup contains sugar and those who don’t are very expensive, so do yourself a favor and make it yourself!

Key ingredients

Here are the ingredients you’ll need to make this sugar-free ketchup. You can find these everyday items at your local grocery store if you don’t already have them in your own kitchen.

  • Tomato paste: Tomato paste is rich and flavorful and the perfect base for the ketchup. Make sure there is no added sugar here too.
  • White vinegar: You can also use apple cider vinegar if you prefer.
  • Sugar-free sweetener: Sweeteners that can be used are erythritol, allulose, monk fruit, or blended sweeteners like erythritol & monk fruit or allulose and monk fruit. Basically, any sweetener that measures a cup of sugar.
  • Water: A little bit helps the consistency to thin out and become easier to spread or dip.
  • Salt: Kosher salt adds and enhances the natural flavors.
  • Dry mustard powder: This adds flavor and helps bind the ingredients, so they don’t separate.
  • Onion powder and garlic powder: Adding some spices makes this dish even more flavorful.

    Storage information & bulk preparation

    To refrigerate: Store the ketchup in an airtight container in the refrigerator for up to three weeks.

    To serve, pull it out of the fridge, spoon some into a bowl, and enjoy as a dipping sauce.

    To prepare in bulk: You can easily make this flavorful dip in a double batch and freeze any that you won’t use right away.

    The best way to do this is to pour it into ice cube trays, freeze, then transfer the ketchup cubes to a large freezer bag and return to the freezer. You can freeze ketchup for up to 6 months.

    This allows you to use what you need instead of thawing the entire batch and only using a small amount.

    1. Love this recipe! I didn’t have enough honey so I had to top the 1/4 c off with a bit of organic maple syrup; and also had to sub Dijon for the dry mustard. Delicious!
