What Tomatoes Are Best for Making Tomato Powder?

When it comes to making tomato powder, you can use any tomato you like, but my favorites are the Italian plum tomatoes. And if you are lucky enough to find fresh San Marzano tomatoes, you’ve hit the jackpot! They have an unbeatable flavor.

Tasty Italian Plum Tomatoes

Italian plum tomatoes are my favorite for making tomato powder because I like to use the skins to make the powder and save the rest of the tomato for another recipe.

For example, I’ll peel and dehydrate the tomato skins and use the skinless tomatoes to make a homemade marinara sauce. Oh, and when making any type of tomato sauce, plum tomatoes are an excellent choice because they are full of flavor and generally have very few seeds.

Use Tomato Skins or the Whole Tomato for Tomato Powder?

To make tomato powder, I like to use dried tomato skins, but you can also choose to use whole tomatoes that you have cut into slices for drying. (Don’t try to dehydrate a whole tomato without cutting it into slices! 😊)

However, keep in mind, if you decide to use slices cut from a whole tomato, you want to use a dehydrator for this process. This is because drying tomato slices in the oven can take quite a bit of time.

Tomato Skins Are Packed with Flavor and Nutrition

Speaking of flavor, you will be pleased to know that the flavor of dehydrated tomato skins is equally as robust as dehydrated slices from the entire tomato.

So don’t worry that you will be missing out on a richer tomato flavor if you only use the skins. And the tomato skins are also loaded with nutrients, so you won’t lose out on those either!

What Equipment Do You Need to Dehydrate Tomatoes?

You don’t need any special equipment to dehydrate tomatoes. You can use your oven or a dehydrator. However, using a dehydrator will make the process easier, since you can usually set your drying temperature lower in a dehydrator than in an oven. For example, I use an Excalibur Food Dehydrator in my recipe video.

The following subsections describe how you can dehydrate tomato skins or tomato slices in your oven or dehydrator.

Dehydrating Tomato Skins: Dehydrator

In my printable recipe, I explain that if you use a dehydrator, you will need to set your equipment temperature to 135°F for about six hours to allow your skins to dry to a crisp texture.

Dehydrating Tomato Skins: Oven

If you decide to dry your tomato skins in your oven, you’ll want to set the oven to its lowest temperature, preferably under 200°F. The drying time will be less than that of the dehydrator.

Most importantly, you’ll need to keep your eyes on the tomato skins and ensure they are drying and not cooking. (If you notice the tomatoes bubbling instead of shrinking, your tomatoes are probably cooking and not drying.) Plus, you never want to allow the skins to burn!

Dehydrating Whole Tomato Slices: Dehydrator

Like tomato skins, you can dry whole tomato slices in a dehydrator. You’ll use the same 135°F temperature setting as the skins. However, the time to dry the slices to a crisp will most likely take at least eight hours and possibly up to 12 hours, depending on the thickness of the slices.

Dehydrating Whole Tomato Slices: Oven

Trying to dry whole tomato slices in the oven will be a challenge. It will be difficult to get them to dry to a crisp, and you will need to run your oven for at least 12 hours. (Understandably, few of us want to leave our ovens running for twelve or more hours!)

Plus, when you try to dehydrate whole tomato slices in the oven, you will need to contend with two potential problems:

  • You need to avoid cooking them.
  • You need to prevent them from burning.

You’re going to spend a lot of time babysitting your tomato skins between the 12 hour drying time and trying to avoid cooking or burning your slices. So, as you can imagine, I don’t recommend trying to dry whole tomato slices in the oven.

Can I Use My Pilot or Electric Oven Light for Dehydrating?

But what if your oven has a pilot light or an electric light? Would turning your oven off, but keeping your oven light on, mimic the environment of a dehydrator?

Unfortunately, based on my experience, I have not found this to work. By itself, your oven light doesn’t produce enough heat for dehydrating. A dehydrator machine also constantly circulates air to help the drying process, and you can’t replicate the airflow with an oven light. And with the lack of heat and airflow, sadly, mold often sets in too!

So, no don’t try to use your pilot or electric oven light for dehydrating.

How to Grind Crisp Tomato Skins or Slices into Tomato Powder

Once your tomato skins or tomato slices are dried to a crisp, it’s time to grind them into a powder, and you can use different kitchen tools for this job:

  • Blender or food processor
  • Mortal and Pestle (If you’re feeling particularly like a pioneer, you can grind your dehydrated tomatoes by hand.)
  • Small spice or coffee bean grinder (I use this equipment in my video, and it’s my favorite way to make tomato powder.)

Plus, you can decide what texture of tomato powder you want. I like to grind my powder finely so that I can mix it with other seasonings, like the ones in my Homemade Seasoning Blends recipe video, to make a perfect homemade blend for topping focaccia. However, you can also just do a quick pulse with any grinder to create tomato flakes.

How Can You Use Tomato Powder?

Here are just a few ways for you to use your homemade tomato powder:

  • Seasoning
  • Soup or Juice
  • Dry Rub

Using Tomato Powder: Seasoning

I like to use my tomato powder as a seasoning. It’s tasty mixed with some sea salt, red pepper flakes, and dried oregano. Afterward, you can add your seasoning to olive oil for a flavorful dipping sauce for Italian bread.

Want to boost the flavor profile of your homemade barbecue sauce? Add tomato powder. You’ll notice the taste of your delightful homemade tomato powder even more when adding it to a store-bought barbecue sauce, since store-bought is usually not as flavorful as a homemade sauce.

Using Tomato Powder: Soup or Juice

You can also add a tablespoon of tomato powder to a mug along with some hot water for instant tomato soup! Or you can use cold water for instant tomato juice.

Tomato powder also comes in handy as a flavor boost for soups and stews, and it will even act as a bit of a thickener.

Using Tomato Powder: Dry Rub

The next time you need a dry rub before grilling your meat, chicken, or fish, try adding tomato powder to the rub. Everyone will be asking you what’s that amazing flavor!

And best of all, you can even use tomato powder as a substitute to any dish that calls for tomato paste. The possibilities for using tomato powder in recipes are endless!

Learn how to make tomato powder from tomato skins to create a tasty flavoring powder you can add to recipes or sprinkle on food.


  • Stockpot
  • Dehydrator or Oven
  • Silicon mats or fruit leather trays, optional
  • Parchment paper, optional


  • 48 medium Plum tomatoes You can use any tomato, but I prefer Italian plum tomatoes.


  • Blanch tomatoes six at a time in boiling water for 30-60 seconds until the skins split and begin to pull away from the flesh of the tomato. (See video.)
  • Submerge each batch of blanched tomatoes into a bowl of ice water to stop the cooking.
  • Remove the cooled tomatoes from the ice water and peel the skin from the flesh of the tomato.
  • Set the skinless tomatoes aside to be used for another purpose. (I made marinara sauce with mine.)

Instructions for Drying Tomato Skins in the Dehydrator

  • Place the tomato skins in a single layer on a silicon-lined dehydrator tray or a dehydrator fruit leather tray.
  • Once you have placed all the skins on dehydrator trays, put the trays into the dehydrator and set the temperature to 135°F. Set the timer for 6 hours.
  • After 1 hour, check the tomato skins to ensure that none are sticking to the dehydrator trays. If any skins are sticking to the trays, simply loosen them.
  • After 6 hours, check the skins to ensure that they have dried to a crisp. (See video.) It is essential to make sure that the skins are completely dry.

Instructions for Drying Tomato Skins in the Oven

  • Place the tomato skins in a single layer on a parchment paper-lined baking sheet pan.
  • Once all the skins have been placed on a parchment paper-lined baking sheet pan, put the pan on an oven rack.
  • Set the oven temperature to its lowest setting.
  • The lowest setting of your oven will determine how long it will take to dry the tomato skins. The warmer the oven, the faster the tomato skins will dry. Drying time may vary from 2-5 hours.
  • Watch the drying process closely. If any of the tomato skins begin to stick to the parchment paper, loosen them.
  • Periodically during the drying time, shake the pans to redistribute the tomato skins to make sure they dry evenly.
  • Once the tomato skins have dried to a crisp, move on to the next step to make your tomato powder. But before starting the grinding process, make sure the skins are completely dry.

How to Make Tomato Powder from Dried Tomato Skins

  • Pulverize the dried skins to the consistency you like. I pulverized the dried skins for approximately 30-60 seconds in a spice grinder to achieve the consistency of a finely ground powder. (See video.)
  • Store the tomato powder in an airtight jar in a cool dark pantry or cupboard. It should retain its tomato flavor for about 3-6 months.
