    You don’t have to give up ketchup with this Sugar-Free Instant Pot Ketchup recipe. This recipe uses fresh tomatoes and is quick and easy.

    Due to the large amounts of added sugar in store-bought ketchup, it is usually one of the first condiments to go when starting a sugar-free lifestyle.

    Luckily, ketchup is easy to make, and with the help of the Instant Pot, you can do it with minimal hands-on time.

    Are tomatoes keto?

    Tomatoes are a wonderful healthy low-carb vegetable that is low in carbs, high in fibre, low calorie, and packed with nutrients, minerals, and vitamins.

    Nutrition values, tomato, red, raw per 100 g: 2.6 g net carbs, 1.2 g fibre, 0.9 g protein, 0.2 g fat, and only 18 calories.

    Nutritional values from cronometer.com

    Ingredients you need

    For this ketchup recipe, you will use fresh tomatoes. This recipe is perfect for gardeners, or anyone who has a couple of pounds of tomatoes in their fridge.

    Perhaps you received a bunch of tomatoes in your food co-op this week and don't know what to do with them.

    All ingredients, quantities, and instructions can be found in the recipe card below.

    • Fresh tomatoes - I used plum tomaotes but you may use whichever tomatoes you prefer or have on hand. Top tip: If your tomato variety is watery, you may want to strain some of the excess liquid before making your ketchup.
    • Fresh mushrooms - diced.
    • All spice - this is one of the traditional spices used in store-bought ketchup. It gives homemade ketchup an authentic taste.
    • Onion powder and garlic powder - two more authentic ketchup flavours.
    • Powdered sweetener - add more or less to your taste preferences.
    • White vinegar - for that tangy ketchup taste.

    How to thicken homemade ketchup

    Tomatoes are naturally watery. Since we cannot use wheat flour or corn starch to thicken the ketchup, I used mushrooms to thicken it. Mushrooms can act as a natural thickening agent.

    Since they are low in carbs and high in fibre they make the perfect addition.

    If you are allergic to mushrooms, or just don’t like them, feel free to leave them out. You will have to simmer the ketchup a little longer to thicken it. This will yield a lower amount of ketchup though.

    Which fresh tomatoes are best ?

    I chose plum tomatoes for this recipe since they are firmer and have a lower water content. You can use any tomatoes, but you will want to keep the water content in mind.

    Some tomatoes, like beef steak, have more liquid than others. If you can’t find plum tomatoes I would recommend grape tomatoes instead.

    How to make sugar-free ketchup

    • A person holding a pot water into the instant pot to make home-made sugar free ketchup
      1: Place all the ingredients into the Instant Pot
    • Instant pot with 10 minutes on the timer
      2: Cook at pressure for 10 minutes
    • Pouring home-made catch up from the blender back into the instant pot
      3: Puree until smooth, then cook again
    • Pouring sugar free catch up into the glass storage jars
      4: Pour into clean jars and store

    1: The first step to make this ketchup is to cut the fresh tomatoes into quarters and chop the mushrooms. This will help the tomatoes cook faster and the mushrooms to soften. Making them easy to blend later on.

    2: Next, you will dump everything in the Instant Pot and cook for 10 minutes. I did a quick release, but if you lose track of time and it naturally releases don't worry. You did not ruin the ketchup.

    3: When the tomatoes are done cooking dump all the contents from the Instant Pot into a blender then blend until smooth. If you have an immersion blender you can use that as well and dirty one less dish.

    At this point, the ketchup will be watery. Just add the ketchup back to the Instant Pot and bring it to a simmer using the sauté function.

    Let the ketchup simmer for about 5 minutes until it thickens. That's all, you now have delicious sugar-free ketchup.

    4: Store the ketchup in a sterilized airtight container in the fridge for 2-4 weeks. Be sure to let the ketchup cool completely to room temperature before closing the lid.

    This will ensure bacteria doesn’t grow in the container causing your ketchup to spoil quickly. You should yield about a pint of sugar-free ketchup.

    How much liquid do I need?

    The vinegar in this recipe adds enough liquid to bring the Instant Pot to pressure.

    Keep in mind the tomatoes will release more liquid as they heat up and break down. I use a 6-quart Instant Pot, if you use an 8-quart Instant Pot you may want to double the recipe to ensure you have enough liquid.

    How to serve

    Having a variety of low-carb sauces can really bring the main meal to life. It also helps to transition kids to stop their regular ketchup that has added sugar and starches.

    It's the perfect sauce to serve with chicken, beef, pork, steak, and of course, garlic bread.

        Yes, you can cook this in a saucepan on the stovetop. I would cook it on a medium-high heat for 20 minutes, stirring occasionally to ensure nothing sticks and burns on the bottom of the pan.

        Yes, but it will take a lot longer. It's easier and quicker to make it on the stovetop or the Instant pot but if you only have a slow cooker, sure thing, that would work. I would estimate 4 hours on HIGH and 6 hours on LOW.

          Just finished making a batch, waiting for it to cool. So incredibly easy! Flavor is perfect but it's still more like tomato soup after about 10 min simmering. Hope it thickens as it cools down

        A pressure cooker is just one of the features as an Instant Pot.

      Do you peel the tomatoes first before putting in the instant pos?

      Do you think that it would freeze well in a plastic container or bag? Would like to make a double batch!

        That would work brilliantly! I would freeze for up to 3 months.
