Place all ingredients in a medium sized saucepan with heat set to medium/low. Stir until well combined (You can use a whisk for this if it’s easier, but I didn’t because I didn’t want an extra dish to wash).
Stir until there are no lumps and water starts to evaporate. Keep mixture on heat until ketchup has reached desired consistency.
Let cool before transferring to storage container. Store in an airtight container in the refrigerator for no more than 2 weeks. Enjoy!
*Can sub equal amount xylitol, cane sugar, or other granulated sweetener of choice
