Preserving Tomatoes as Dehydrated Tomato Powder

Preserving Tomatoes as Dehydrated Tomato Powder
Home » Preserving Food » DIY tomato powder

There is no comparison between the sad tasteless grocery store tomatoes of winter and the fresh summer tomatoes which are packed with umami, a bit of sweetness and a touch of acid. There is an option however for that fresh tomato taste in winter. Dehydrating mid-summer tomatoes in their peak and then grinding them to a tomato powder can stand in for fresh tomato flavor in many dishes, and it’s easy! (Video included)

Enhancing Flavor of Tomato Powder

In it’s simplest form, tomato powder is simply dried tomatoes that have been ground into a powder for long term storage and use. As with other dehydrated fruits and vegetables, the sugars concentrate and the flavor tends to intensify so you don’t need to add very much to get a lot of punch in return.

Tomato powder is typically just one ingredient (the tomatoes), but adding some salt to the powder will enhance the flavor and also keep it from clumping over time.

Salt is a preservative and will keep the powder fresh longer, as well as preventing clumping. If you do add salt, just be sure to modify your recipe if it also calls for salt. You don’t want to oversalt.

If you happen to be a tomato aficionado and grow or buy different varieties of heirloom tomatoes, you can also add nuanced flavor to the powder by choosing heirlooms with specific flavor profiles.

**Tip: Tomato powder is rich and a bit sweet and it pairs well with paprika and/or garlic

How to Dry the Tomatoes?

While extremely easy to make, just know that tomatoes do take some time to dry, especially the juicier ones. Roma tomatoes won’t take as long because they are meatier, but I find many Romas don’t have the robust flavor that I like in a tomato. I opt for the meatiest beefsteak-type tomatoes I can find.

Most often the tomatoes are dried in a dehydrator, but it is possible to dry them in the oven or outside in a warm, dry climate.

It is also possible to dry tomatoes in an oven. Most ovens won’t go under 200 degrees however, so if you are drying in an oven, make sure and check them more often. Also know that they will probably be a darker color if you are drying in an oven.

Dehydrator Method:

The beauty of the dehydrator is control. A dehydrator allows you to control the temperature and sometimes the time, depending on the dehydrator.

I generally cut them into 1/2” slices (they will shrink a lot) and place them in the dehydrator at 135 degrees F for 12-24 hours. The lower heat allows the tomatoes to preserve their bright color, adding a nice visual element to your dish. Higher temperatures will render darker tomatoes and can also burn them, resulting in a bitter taste.

Check them every so often until they are no longer pliable and then grind them up in a coffee grinder and you’re good to go.

**Pro Tip: Don’t oil the dehydrator racks. Oil on the fruit or vegetable being dried can cause spoilage and rancidity during long term storage.

How to Use Tomato Powder in Cooking

Let me count the ways. It’s a perfect option not only for replacing tomato juice, paste, and sauce, but if you get a bit more creative, the uses are endless.

Here are some of my favorite ideas for using tomato powder. Remember to add salt to these ideas to bring out the best of the tomato flavor (if you didn’t add salt to your original powder).

  • Add a tablespoon to savory winter stews or pasta sauces (flavor-wise, a tablespoon of the powder can replace a can of tinned tomatoes
  • For a tomato sauce, use 1 part powder to 2 or 3 parts water, And 1/4 tsp salt
  • Shake it up with an oil and vinegar salad dressing
  • Use it as a secret ingredient in dry rubs or BBQ rubs. Mix tomato powder, salt and your other favorite dry rub ingredients, apply to chicken or beef and grill or roast as a sheet pan dinner
  • Reconstitute tomato powder with hot water, add some herbs and then add it to your pizza as a sauce (or fold it into the dough if you make your own pizza dough)
  • Rehydrate the powder with heavy cream and add to your scrambled eggs
  • Use it as a rub for roasted vegetables. Shake on, toss with oil and roast in a 350 degree oven.
  • Make a homemade spanish rice
  • Add more robust flavor to your salsa by adding some powder to the chopped grocery store tomatoes
  • Mix it with parmesan or powdered cheese and sprinkle over popcorn
  • Make a homemade spanish rice
  • Add it to your Bloody Mary 
  • Add it to mayonnaise for a zesty, creamy sandwich spread. 
  • Mix tomato powder and herbs into some cream cheese to use as a spread for crackers
  • Add it to a meatloaf recipe
  • Stir it into bread doughs or pastry dough (sourdough bread anyone?)
  • Add to deviled egg toppings
  • Sprinkle on top of hummus

**Tip: If the dish you are making does not have added salt, be sure and add 1/4 tsp or so. It will really enhance the flavor profile of the tomato powder. Some people ad a little bit of sugar also, but that is usually not warranted unless you have tasteless tomatoes to begin with.

General Ratios for Making Tomato Products from the Powder

In the following recipes (except for the spice blend), always simmer the powder with the water while stirring or whisking to fully dissolve the powder and thicken the sauce.

Tomato Paste: Start with a 1:1 ratio of powder to water and then simmer it down to the desired consistency. Add salt to taste.

Tomato Sauce: Depending upon how thick you want your tomato sauce to be, you will want to add somewhere around 1 part of water to 1 part tomato powder. 1/2 cup tomato powder + 1/2 cup hot water + salt to taste makes about 8 ounces

Enchilada sauce or pizza sauce: For a thinner sauce for something like enchiladas or a pizza sauce, you will want to add more water. 1/2 cup tomato powder + 1 – 1 1/2 cups water + salt to taste

Italian Spice: For 3-4 T of mix, blend 1 T tomato powder with 1 1/2 t dried onion, garlic, basil, parsley, and oregano, and 1 t salt

How to Store

Store the dried and ground powder in an airtight containers. If you store them in plastic bags, remove as much air as possible before sealing them.

You can store the dried tomatoes at room temperature if they have been thoroughly dehydrated. If you haven’t got them completely dried, you will need to store in the fridge to help keep mold from forming on them.

I don’t recommend storing in oil. It can go rancid and it is not as safe as storing them in dried form.

One of the really nice things about tomato powder is that it doesn’t take up much room and it can last indefinitely if it was thoroughly dehydrated.

  • ¼ Tsp Salt Optional


  • Rinse tomatoes and pat dry. Slice tomatoes approximately 1/2” thick. You do not need to peel, de-seed or core.

  • Lay the slices on the dehydrator trays, in a single layer. You won’t need to turn the tomatoes
  • Set the dehydrator to 130 – 135F. The time it takes to dehydrate will vary depending on the tomatoes you use, but they’ll take at least 8 hours and probably more. Check them at the 8 hour mark first. Tomatoes should be crisp and not at all pliable.
  • Once the tomatoes are 100% COMPLETELY dry, peel them off of the trays and place them in your blender or food processor. Blend the tomatoes for about 30 seconds, and then let the machine cool for about 30 seconds. Repeat until all the tomatoes are a fine powder.
    If you are using salt, add it to the blender when grinding.

**If you package your product in mason jars with the metal rings and lids it will stay good for at least a year. Don’t use the plastic storage lids they sell, they are not air tight. If you use a vacuum sealer (foodsaver) with a mason jar attachment, you can store dehydrated fruits and vegetables for years.

    This was very helpful! I plan on trying out many ways to use tomato powder.

  2. T Gore says:

    Have made many rubs and powders over the years. A little hint I have discovered is to add about 10 grains of uncooked rice to the spice mill when grinding the herbs and doesn’t effect the flavor but prevents caking in humid conditions..

    • Perfect. Thank you for the tip. I do get some caking with a few of my spice blends but I’ve been reluctant to add the anticaking product (not really sure what is in it). I’ll try your rice tip on my next batch!

  3. Kathryn Uptain says:

    Can I add salt to my tomato powder? Thought it might help deserve it and keep it from clumping? Thank you in advance.

    • Yes, please do add salt. It not only helps to preserve it, but it “deserves” it also lol. Actually salt brings out the flavor more also. I just avoid it because I sell the product and a lot of people can’t take much salt. A lot of processed food is oversalted but anything you make at home should have salt in my opinion. It’s much harder to oversalt if you cook at home.

    Preserve it not deserve it. Sorry for the typo.
