  • Food Dehydrator, or Oven
  • Blender, food processor or coffee grinder
  • Airtight storage container


  • Tomatoes or tomato skins (cherry tomatoes make super flavorful tomato powder!)


  • To make tomato powder using tomato skins only, skip to step 4.
  • Using whole fresh tomatoes, start by washing and cutting the tomatoes. Cut cherry tomatoes in half, small tomatoes into quarters, and larger tomatoes into thin even slices. (It’s important to try to keep all your tomato pieces roughly the same size and thickness so they’ll dry evenly)
  • Squeeze or scoop out the seeds and guts to expedite drying time.
  • Place cut tomatoes skin side down on dehydrator drying racks (or on oven baking sheet) in a single layer, not overlapping.
  • Using a food dehydrator, dry the tomatoes on 135-145 degrees F (OR in an oven on the lowest temperature possible) until they're completely dry and crisp. This will take several hours to a couple days, depending on your machine and how large your tomato pieces area. (Skins will dry MUCH faster)
  • The tomatoes are “done” drying when they’re crispy and no longer soft or chewy. They’ll be a lot more firm than sun-dried tomatoes, and should snap in half rather than bend.
  • As soon as they're finished drying, use a blender, food processor, or coffee grinder to pulverize and grind the dry tomatoes into a fine powder.
  • Store tomato powder in an airtight container with a lid in a cool dark location.
  • Homemade tomato powder should last up to a year (or longer) when dried and stored properly. Discard if mold develops. Otherwise, enjoy!

How to Turn Tomato Powder into Tomato Paste

  • Mix 1 to 2 parts water with 1 part tomato powder. For instance, combine 1 to 2 tablespoons of water for 1 tablespoon of tomato powder. Start with a 1-to-1 ratio and then gradually add more water to adjust the consistency of the tomato paste to your liking.
