Homemade tomato sauce is very simple to make in the Thermomix, and contains a lot less sugar than the bought stuff, plus no preservatives and colours! Here’s how I make my sauce (or ‘ketchup’), which we use just as an everyday tomato sauce and also as a baking sauce for chicken, ribs, roast, meatloaf, etc. 

When I’ve got to go out for the day, I often just throw some chicken pieces or beef ribs into the crockpot, pour this sauce over, and leave it to cook until tender (usually 4 hours on high, or 8 hours on low – except beef ribs which take about 6 hours on high and I add a bit of water so they don’t dry out). Adjust seasonings to taste, and try some of the variations below the recipe to get it just how you like it.

Note: This sauce won’t be quite as red as bought tomato sauce, but tastes very rich and delicious!

Quirky Cooking


You can play with the flavour, adding in one or more of the following if you like, and adjusting the sweetness (and sweetener) to taste:

fresh basil and/or oregano or chives
a little rosemary or thyme
black pepper
smoked paprika
a red chilli or chilli powder
a few sprigs fresh parsley

Note: In the fridge this will keep a few weeks. Or if you like you can put it into glass jars or bottles with screwtop lids that will seal well, then boil the sealed jars for 15-20 minutes to vacuum seal. This way you can keep it in the pantry indefinitely until opened. (After opening store in the fridge.) Thanks for this tip Bee!

    Thanks for this recipe. It’s amazing. As your recipes always are 🙂 just wondering if you’ve ever made it more chunky so it’s like a chutney? I’d love to make chutney but every recipe I find has sugar in it and I love the dates in this one instead

  3. sabrina Borovina says:

    Fantastic! Thank you for sharing and I’m definitely going to make this as a gift for chrissy. So tasty and nutritional so I don’t mind my boys getting stuck into it.

  4. Kristyn says:

    This is the best sauce I’ve ever tasted!

  5. Margaret Rose says:

    I made this using dates as the sweetener but found it way to thick and had to add a lot of water to thin it out. Other than that, simple and delicious.

  6. Alison says:

    Why do you need tomato paste in the recipe?

  7. Pixi bowen says:

    As I am doing low carb/keto can the sugar be replaced with something like stevia ?

    Very glad to have found your site – lovely recipes

    I decided to make this last minute and was outraged at the price of tomatoes at the supermarket so I bought two 400g tins of whole, roma tomatoes. I made no other changes (used sundried tom and honey) and the recipe turned out delicious! My husband said it tasted better than my other batches made on fresh tomatoes. I’d prefer to use fresh tomatoes – but it’s good to know this can be made last-minute, with pantry staples.
