Homemade Tomato Paste – Super Fresh From The Garden!

Ok , how many ways can I use these bazillion tomatoes from my garden? A lot of different ways, actually!

Roast, roast, roast! I always roast the tomatoes first, before processing. It makes a huge difference!

This is a view of one of the sheet pans I used for making the tomato paste in the oven. The orange vs red is because I had 2 different batches of tomatoes roasting and both batches had very different varieties of tomatoes in them. 🙂

It is seriously worth it to make this yourself. You control the ingredients, you ALWAYS have some around when you need it. I can’t even count how many times I’ve needed tomato paste and have been out. Not anymore! I like to store mine in the fridge and in the freezer. I use it often enough and it lasts a long time! Just don’t forget to store it with olive oil on top.

It’s so easy. No excuses! If you have tomatoes, you can make this!


10 pounds tomatoes

2 tablespoons olive oil

2 teaspoons sea salt

1/2 teaspoon citric acid


Chef’s knife

Cutting board

Large saucepan

Food mill, sieve, or chinois

8oz Bell Canning jars


1 Preheat the oven to 350°F.

2 Chop tomatoes into quarters.

3 Simmer the tomatoes with the olive oil: Combine the chopped tomatoes and olive oil in a large saucepan. Bring to a simmer. Cook until the tomatoes are soft and the peels begin to detach from the tomato flesh.

4 Pass the tomatoes through a food mill: Push the warm tomatoes through a food mill, sieve or chinois to separate the tomato pulp from the seeds and skins. Stir the sea salt and citric acid into the pulp. Discard or compost the seeds and skins.

5 Divide the tomato pulp between two large, rimmed baking sheets. You can also use a large roasting pan, but it will take longer to cook down that way.

6 Bake the tomato pulp until reduced to a paste: Place the baking sheets in the oven. Check the tomatoes every half hour, stirring the paste and switching the position of the baking sheets so that they reduce evenly. Over time, the paste will start to reduce to the point where it doesn’t fill the baking sheet any more. At this point, combine the contents of the two pans into and continue to bake.

7 The paste is done when shiny and brick-colored, and it has reduced by more than half (3 to 4 hours). There shouldn’t be any remaining water or moisture separating from the paste at this point. This will take 3 to 4 hours, though exact baking times will depend on the juiciness of your tomatoes.

8 Divide finished paste into Bell 8 oz jars, leaving 3/4 inch headspace.

9 Preserving Option 1 — Process the tomato paste in a hot water bath: Apply lids and rings and process in a boiling water bath for 15 minutes.

10 Preserving Option 2 – (My favorite) Refrigerate or Freeze: If you don’t want to process the paste, you can refrigerate or freeze it instead. Scrape finished paste into clean half or quarter pint jars. Top each jar with a layer of olive oil and place in either the refrigerator or the freezer. As long as you keep it well-covered with olive oil and ensure that you only use a very clean spoon to remove it from the jar, it will keep in the fridge for 3 to 4 weeks. Frozen, it will keep for up to nine months.

Happy cooking!
