Easy keto ketchup recipe

Most store-bought ketchup (and a variety of other dips and condiments, for that matter) contain added forms of sugar ranging from cane sugar, to high fructose corn syrup, to dextrose, and more.

More than other condiments, ketchup is one of the major culprits that are highest in sugar content. Just 1 tablespoon of Heinz Ketchup contains 5 grams of sugar!

Is ketchup vegan?

Ketchup is typically vegan-friendly. This particular recipe does contain Dijon mustard and some vegans do not consume Dijon because of the wine used to make it (the filtering process of wine often uses animal-based agents). If you do not eat Dijon mustard because you follow a vegan diet, but want to make this keto ketchup, simply sub in yellow mustard at a 1:1 ratio.

Monk fruit sweetener is a keto-friendly sweetener that contains 0 grams of net carbs. You can read more about it in this post all about monk fruit sweetener.

Monk fruit sweetener is widely available at many grocery stores. I personally purchase mine online and have it directly shipped to me.

Instructions

  2. Over low heat, simmer ketchup mixture until thickened, about 20 minutes, stirring occasionally.
  3. Remove pan from heat and, once cooled, taste and add additional salt based on your taste preference. Optionally, using an immersion blender, pulse mixture until desired consistency is reached (I did not do this and the mixture was smooth). Transfer prepared ketchup to a glass jar and chill in the refrigerator before stirring and serving.

Recipe Notes:

Tomato Purée Substitution: Make 1 cup of homemade tomato purée by combining 1/3 cup of tomato paste with 2/3 cup of water.

Golden Monk Fruit Sweetener Substitution: Classic Monk Fruit Sweetener, erythritol, Swerve, or Truvia can be used at a 1:1 ratio. If you are wanting to use liquid stevia or powdered stevia, be sure to check the brand’s website for measurement conversions (pure stevia is not a 1:1 substitution for monk fruit sweetener).

Where Monk Fruit Sweetener Can Be Purchased: Monk fruit sweetener can be purchased in some speciality food stores or online. If you want to order your monk fruit sweetener online, you can use discount code REALBALANCED for 20% OFF your order!

Red Wine Vinegar Substitution: White wine vinegar or apple cider vinegar can be subbed in here at a 1:1 ratio.

      Hi, Judie! There is refrigeration storage recommendations listed in the blog post and recipe card already (store ketchup in a glass container in the refrigerator for up to 1 week. Stir between uses.). As for freezing it, I’m sure it would work, I just haven’t personally tested that. If I were to guess, I would say to freeze in an airtight container and, when you’re ready to eat it, unthaw it overnight in the refrigerator or you could even unthaw it on the stovetop or in the microwave. It also may be a good idea to freeze in a silicone ice cube tray; that way, you can pop out as much ketchup as you’d like to unthaw just that when you’re ready to eat it.
