Homemade Tomato Paste For Canning

Golden Thyme Homestead

You need pounds of tomatoes! Choose a variety that is meaty and not too watery. Roma-style tomatoes are ideal as a low-moisture, low-seed variety.

Let’s get started!

Prep Tomatoes


Core tomatoes, and 1 pound at a time slice them in quarters and add them to a hot large pot to mash.



Reduce heat and allow to simmer until mixture is reduced by ½ and vegetables are cooked.

Strain Mixture


Place your tomato mixture through a food mill or use a wooden spoon to press the mixture in batches through a fine mesh strainer

Second Simmering


Return the remaining tomato mixture to the stove, add citric acid and seasonings, and simmer for 2-5 hours until it thickens to a paste.

Can Finished Paste


Funnel hot paste into hot sterilized jars leaving 1/2 inch headspace. Process jars for 45 minutes (accounting for altitude).
