Start by harvesting fresh tomatoes. They should be ripe or nearly ripe with solid red flesh and no soft or bad spots. You start by harvesting fresh tomatoes. They should be ripe or nearly ripe with solid red flesh and no soft or bad spots. Roma tomatoes are preferred if you have access to them, but other varieties will work too. Wash and set aside for now. This is not a quick recipe, but it is easy and so worth the effort.

Decide if you want to freeze or can your ketchup. Wash and organize your equipment for whichever method you plan on using. I have both frozen and canned this recipe in 4 – 8 ounce jars. After opening, it will keep for about 10 – 14 days in the refrigerator. Plan the size of your containers based on how quickly you expect to finish a container.

Many recipes you find start with tomato paste, or if they use fresh tomatoes, they will blanch the tomatoes to remove the peels. I don’t do either.

After washing, remove the stems. Cut the tomatoes into quarters. Remove most of the seeds and liquid from inside the tomatoes. If there are a few seeds left behind, don’t worry about it. You will blend the ketchup after cooking, and this will take care of any strays.

Cooking Your Sugar-Free Ketchup Recipe

Put the tomatoes in a large soup kettle or stockpot. Mix in all the other ingredients.

Place on the stove over medium heat or medium to high heat. Cook until it just starts to bubble. Change your burner to low heat to maintain a simmer. Continue cooking at a slow simmer, stirring frequently, until the mixture has cooked down to the thickness of commercial ketchup. Your ketchup will also thicken a bit as it cools.

Finishing and Storing Your Homemade Ketchup

After the mixture is at the consistency you desire, use an immersion blender to break down the peels and any stray seeds that remained. Continue to blend until you achieve a smooth texture.

If you are planning on water bath canning your Sugar-Free Tomato Ketchup, it is a good practice to check the acidity level of the tomatoes. This is done simply by using PH strips dipped in the final mixture.

Follow recommendations for acceptable PH level for water bath canning method.

Transfer your sugar-free ketchup into either freezer containers. If you prefer, your ketchup can be canned by the water bath method, following instructions for tomato sauce. And of course, keep any leftovers out to use fresh!

Enjoy!
