Turn your tomato skins into tomato powder by baking them in the oven or food dehydrator and then grinding into a powder. This is great no waste recipe that every gardener needs to make!

Homemade Tomato Powder

It’s raining tomatoes!  Don’t I always say that during July and August? Well it’s true – we have so many tomatoes right now! You guys know I love my Stewed Tomatoes recipe and Roma Tomato Soup but with that comes a lot of extra tomato skins.

Being one that loves to use up the whole fruit or vegetable, I wanted to come up with a way to use use the tomato skins in a way that can be enjoyed in different recipes throughout the seasons.  By making tomato powder we can enjoy our Summer tomato harvest, even during Winter!

Since I know not everyone has a food dehydrator I will supply both methods below – for making it in a food dehydrator and in the oven! Whatever way you choose, I hope you like it!

Love making homemade spices? Check out my homemade onion powder, garlic powder, adobo seasoning, dried basil, dried parsley, and dried oregano too!

How to Use Tomato Powder

Here are some great ways to use tomato powder in everyday recipes:

  1. Sprinkle on slices of pizza. (try this pizza dough!)
  2. Use as a meat seasoning. (great for oven baked burgers!)
  3. Use on sandwiches or subs.
  4. Throw in soups (like slow cooker barley sausage soup – pictured below!), stews and chili.
  5. Throw in pasta dishes.
  6. Use in fritters batter, like these zucchini corn fritters or mashed potato patties.
  7. Throw in tomato sauces for more tomato flavor!
  8. Popcorn!

How to Make Tomato Powder in the Oven

Preheat your oven to a low temperature, around 150-170 degrees F. (Up to 190 degrees F is ok if that’s as low as your oven goes).

Gather your tomato skins. These can be leftover from canning, making tomato sauce, or peeling fresh tomatoes. Make sure they are clean and free from any debris.

Line a baking sheet with parchment paper. Spread the tomato skins evenly on the baking sheet, ensuring they are not overlapping. This helps with even drying.

Place the baking sheet in the preheated oven. The drying time can vary but generally takes around 4-8 hours, depending on oven temperature and how wet the tomato skins are.

After a few hours, check the tomato skins for dryness. They should be brittle and easily snap. If they are not completely dry, continue to bake and check at 30 minute intervals until they are ready.

Once the tomato skins are fully dried, remove them from the oven and let them cool to room temperature. This prevents condensation from forming when you store them.

Transfer the cooled, dried tomato skins to a coffee/spice grinder or food processor. Pulse until you achieve a fine powder consistency.

How to Make Tomato Powder with Food Dehydrator

  1. Collect your tomato skins, ensuring they are clean and free from debris.
  2. Lay the tomato skins on dehydrator sheets and dehydrate them at 135 degrees F for 8-12 hours until they become brittle and lose all moisture.
  3. Transfer the dried skins to a coffee grinder and process them until you have a fine powder. Store the powder in an airtight jar.

Want to make tomato flakes instead?

If you prefer flakes, place the dried skins in a food processor and pulse a few times until you achieve the desired flake consistency. Store the flakes in an airtight jar.

How to Store Tomato Powder

Transfer the tomato powder to an airtight container. Store it in a cool, dark place away from direct sunlight and heat. Using a vacuum-sealed container can also help extend its shelf life.

Homemade tomato powder should last up to a year (or longer) when stored properly.

Ingredients

  • Tomato skins (as many as you have)

Instructions

To Make Tomato Powder in the Oven

  • Preheat your oven to a low temperature, around 150-170 degrees F. (Up to 190 degrees F is ok if that's as low as your oven goes).
  • Line a baking sheet with parchment paper. Spread the tomato skins evenly on the baking sheet, ensuring they are not overlapping.
  • Place the baking sheet in the preheated oven. The drying time can vary but generally takes around 4-8 hours, depending on oven temperature and how wet the tomato skins are. After a few hours, check the tomato skins for dryness. They should be brittle and easily snap in half. If they are not completely dry, continue to bake and check at 30 minute intervals until they are ready.
  • Once the tomato skins are fully dried, remove them from the oven and let them cool to room temperature. This prevents condensation from forming when you store them.
  • Transfer the cooled, dried tomato skins to a spice or coffee grinder. Pulse until you achieve a fine powder consistency.
  • Transfer the tomato powder to an airtight container or spice jar. Store it in a cool, dark place away from direct sunlight and heat. Tomato powder should last up to a year (or longer) when stored properly.

To Make Tomato Powder in Food Dehydrator

  • Gather your tomato skins. Place on dehydrator sheets. Dehydrate at 135 degrees for 8-12 hours until brittle and no longer wet. For powder: Put dried tomato skins in coffee grinder and grind until powder. For flakes: Put dried tomato skins in food processor and pulse a few times until flakes. Store in an airtight container in a cool, dark place away from direct sunlight and heat. Tomato powder should last up to a year (or longer) when stored properly.

    I was reading about your tomato powder and I would love to try it out. Now my problem is I don’t have a dehydrator, could I use the oven to dry the skins out and get the same outcome.

    Tried this and I could not ever get skins brittle . Dried for 6 days still not brittle enough to chop up. Does it matter on type of tomato used?

      Hi Terry, how are you drying your tomato skins (for 6 days?!)? I would suggest using an oven to dry them or food dehydrator if you have one.

    I use the whole tomato for my tomato powder. I live in a small cabin, not much storage. Powdering saves a lot of space. I prefer cherry tomatos. I just half them place them skin side on trays and dry. Process them in a coffee grinder, wala powder. I use for sauces, chili, etc.

      Yes! Lay them out on parchment paper on a cookie sheet and bake at 200 degrees for 3-4 hours until dried. I just did it today. I had one pan that took way longer as I had put too many skins on it, so definitely don’t overlap!

      Hey Heather, you could. Just put them in at the lowest temperature and watch them closely until crisp.

    Hey Emily, I do my tomato powder with a twist. I roast and can 40-50 quarts of Roma tomatoes every fall. I use my outdoor gas grill to get a good char on the tomatoes and also help with removal of skins. I usually have a ton of skins. I then cold smoke the skins in my electric smoker. I use a fruit wood like apple or peach to smoke them. Them flavor profile is amazing with a ton of umami. Fresh tomato basil pasta dishes never tasted so good! One tip is just make enough to use over the winter and freeze the rest of the roasted skins in baggies. Pull out a bag of skins and smoke them and your good to go! I call it “Essence of smoked tomato skins”

    Any idea how long the shelf life would be on tomato powder? I too have it in a mason jar in my spice rack.

      Hey Emily, I’ve had some for over 2 years and it’s fine! But then again I’m not the first to throw out spices! 😉
