You can use sugar free tinned chopped tomatoes or a sugar free passata in it’s place. The recipe also requires tomato paste to thicken the sauce and make it richer. Again, make sure you check for additives such as sugar in any tinned tomato products.

Tomatoes do contain natural sugar so if you ate a lot of them you could be pushing your carb limit. Tomato sauce or ketchup is always going to be high in carbs because of this. Because this is a condiment and served on the side of foods, you would be hard pressed to consume a huge number of carbs. If you had 1 tablespoon or 1 serve of this delicious sauce, it contains less than 1 net carb, which is a lot less than the amount you would consume by using a store bought sugar laden brand.


Because this sauce is cooked off and vinegar is used, it helps your sauce/ketchup to last longer. It should remain fresh in an airtight jar in the fridge for about two weeks. The recipe also freezes really well, so make it in batches to defrost for another time.

Recipe Notes

If you don't have the time you can just blitz this sauce and not cook it. The sauce won't be quite as rich and thick. Reduce amount of water added to 2 tablespoons if you do this.
Because emulisifiers aren't added to this recipe, the sauce can separate slightly. Simply stir to get a smooth texture again.
