How To Make Tomato Powder and Use It, Too

Knowing how to make tomato powder and use it is one of the keys to getting your time and money’s worth from the tomatoes in your garden.
If you’ve ever made salsa, you’ve probably looked at that pile of tomato skins, seeds, and pulp and felt just a little ripped off. Well, no more! Rather than tossing those parts of the tomato away, turn them into tomato powder.
How To Make Tomato Powder
Not into canning or making fresh salsa? You can turn mealy tomatoes, or ones that are about to go bad (cut away any black spots) into tomato powder, too. Now you don’t have to feel guilty for not using your produce quickly enough.
Step 1. Prepare the peels
Squeeze tomato peels dry with a clean towel then scatter them on a dehydrator tray. If you don’t have a dehydrator, spread the peels in a single layer on a baking sheet. (I use this inexpensive dehydrator.)
Step 2: Prepare the pulp
Pulp left from seeding tomatoes for sauce isn’t a kitchen scrap to throw away — turn it into homemade tomato powder. Just line a dehydrator tray with a piece of parchment or wax paper to fit. If you don’t have a dehydrator, line a baking sheet with parchment paper or a silicone baking mat. Spoon the tomato pulp onto the sheet and spread it thinly using a spatula.
Step 3: Dry them
Turn your dehydrator to 135°F/57°C, or pop the baking sheets into a 180°F/82°C oven, and check the trays regularly. For dehydrators, you’ll want to rotate the racks hourly. If using an oven, rotate them after two hours.
The skins are usually the first to dry — around 4 hours in my dehydrator — followed an hour or two later by the pulp. You’ll know when it’s dry enough because you can crush it in your hand easily.
Step 4: Cool them
Remove the trays from the dehydrator or oven but leave the tomato peels and pulp on them. Let them sit until they’re completely cooled, even overnight. Waiting overnight allows any remaining moisture to evaporate and keeps your tomato powder from clumping during storage.
Step 5: Powder them
Once completely cooled, tip the skins into a blender or food processor and whir them until they’re powdery. If you’re doing just a few peels, you can even use a clean coffee grinder. Dump that into a bowl and repeat using the tomato pulp. Combine the two and transfer the powder to airtight storage containers or vacuum seal small bags of the stuff.
Tomato Powder
Equipment
- Dehydrator OR baking sheets if using oven
- Parchment paper
- Blender or food processor
Ingredients
- 2 cups Tomato skins and pulp
Instructions
- Squeeze the tomato skins in a paper towel to remove as much moisture as possible.
- Spread the tomato skins on one unlined dehydrator tray and the pulp on another one lined with parchment. If using an oven, spread on lined baking sheets.
- Turn your dehydrator to 135°F/57°C. For oven-drying, place the sheets in the middle of the oven and set it to 180°F/82°C. Rotate dehydrator racks or baking sheets every 30 minutes. Remove the skins when they’re papery and the pulp when it’s completely dry.
- Let cool completely on the counter until room temperature. Transfer to a blender or food processor and blend on HIGH until powdered. Store in an air-tight container.

How To Use Tomato Powder
Once you know how to make tomato powder, you’ll find it an amazingly versatile addition to your pantry. I often stir it into soups or stews, sprinkle it on scrambled eggs and pasta, and even use it to jazz up a homemade vinaigrette. Basically, add it to anything that you want a bit of oomph and extra tomato flavor. Here are some other uses for it:
Tomato paste: Only need a tablespoon or two of tomato paste? Don’t open a can. Mix 2 parts powder to 1 part water to make as much or as little tomato paste as you need.
Tomato sauce: Combine 1 part tomato powder with 6 parts water to make tomato sauce. To make the equivalent of a 15-oz can use 1/3 cup tomato powder and 2 cups of water.
Tomato juice: Stir 2 tablespoons tomato powder into 8 ounces of cold water for a refreshing tomato juice without all the nasty sodium and preservatives of the store-bought stuff. (Add a splash of clam juice for homemade Clamato.)
Instant tomato soup: Stir 2 tablespoons of tomato powder into 8 ounces of boiling water. Add a pinch of onion and/or garlic powder, and season with salt and pepper to taste. Mmmm, good!
Pizza sauce Combine 1/2 cup tomato powder and 1 1/2 cups water in a saucepan. Bring to a boil, reduce heat and stir in 1/2 teaspoon each of garlic powder, oregano, and basil, plus a pinch of salt. Add 1 tsp. of sugar to counter the acidity, and simmer until the sauce is thick.
Tomato cream cheese: Stir 1-2 tablespoons into softened cream cheese for a delicious sandwich filling or schmear for your bagel.
Now that you know how to make tomato powder and use it, don’t let those peels and pulp or the mealy tomatoes on your counter go to waste!
Let’s say you purchase 16oz. of whole tomatoes from your local big-name supermarket. You steam them, ice ’em, and peel the skins; remove the seeds, and make them into 12oz. worth of tomato sauce that you’ll use later. At $1.49 a pound for tomatoes, that’s a bit more expensive than the $0.99 15oz. can of store-brand plain tomato sauce.
Would you get enough tomato powder from the scraps of making the 12oz. tomato sauce that if you turned it all into paste, and compared it to a like amount of generic canned paste, it would make/exceed the cost deficit?
I suppose the bottom line is – Can this still be cost effective with purchased tomatoes as opposed to gardened ones?
I wouldn’t bother doing such a small amount, personally. I make tomato powder from the scraps left after making ketchup or tomato sauce. The juice gets canned as tomato juice. So, basically, I’m getting three products out of any tomatoes I buy, which is what helps make this more economical.
As for the price of tomatoes, I pay $0.99 a pound at our green grocery, but in about 3 weeks the grocery stores will be running tomatoes at $0.50 a pound. Local farmer’s markets also have tomatoes very cheap this time of year, too.
Where I live it’s pretty common to see local gardeners selling home-grown tomatoes out of the back of pickup trucks or lemonade-style stands at the gas station or garden center. I often wait until they’re getting ready to close up then offer to buy whatever they have left. Doing that, I’ve managed to get tomatoes as low as $0.30 per pound because they don’t want to haul them home.
So to answer your ultimate question: it’s cost-effective if you’re a good shopper, and if you’re using the tomatoes for more than just converting them into powder.
How long is the powder good for ???
I’d treat it like any dried, ground herb and use it within two years.
Woah. And another woah. I have never heard of doing this before but it’s brilliant!!! How long do you think the powder will last in a mason jar? I’m wondering too if I could freeze the powder. The last time I grew tomatoes I wept at the amount of stuff that was wasted.
Providing you completely dry the stuff, it should last at least a year. You could always toss one of those moisture-absorbing packets (the kind you find in new handbags or shoe boxes) and it’ll last even longer.
This looks like a great idea! I recently canned diced tomatoes, so I only have the skins. The pulp and seeds stayed in the jars. I was wondering if the power will still turn out if I only process the skins?
Absolutely! In fact, you’ll probably get a smoother powder from it.
I dry my excess tomatoes as above then freeze them as dried slices. When I use them I grind them in a nutribullet and add them to sauces to thicken them and add flavour. Have always still been good at a year in a ziplock palstic bag. takes up very little space.
That’s a wonderful way to do it, Kazevac!
Thank you so much for this very complete, useful post. I am wondering about the pizza sauce recipe: what is the other spice besides garlic powder that is meant when you say 1/2 tsp “each”? Again, many thanks!
Thank you for catching that, Becky! I’ve fixed it so now it reads 1/2 tsp. each garlic powder, basil, and oregano, plus a pinch of salt. 🙂
Can you give more thorough measurements for tomato paste and tomato sauce. Thank you.
When a recipe calls for 1 part of one ingredient to 6 parts of another, you adjust it based on how much you want to make. The tomato sauce use, for example, says 1 part tomato powder to 6 parts water. You can make those parts teaspoons, in which case you’d use 1 teaspoon of tomato powder and 6 teaspoons of water. Or, you could make them cups and combine 1 cup of tomato powder and 6 cups water.
After you think it is to old put in compost pile.. Mine are vacuum seals in canning jars. Over 1 year old fast fine still. Also if you grow worms for your garden… I make a mix vegie blend. Add water put in ice tray. Frozen worm food. They thrive on it
Hi Katie,
This is my first time coming across your website…and what a happy delight! I’ve been looking for recipes all day for Ketchup
made with tomato powder. I see where you’ve mentioned making ketchup from tomato powder…..I wonder if you please share
your recipe with us?!?? It would be Highly Appreciated. Thank you in advance.
I made tomato powder last night. It seems to wasnt to get clumpy. Any ideas how to not have it clump into one blob?
It’s possible that it’s not fully dry. Even though you’ve already powered it, you can dry it a bit more to see if that helps. Just keep an eye on it, to make sure it doesn’t burn. Another option is to mix it with a little cornstarch, but that will thicken whatever you use it in. I’ve found the very best solution is to add a silica packet to the container. You don’t have to buy them — they often come tucked inside shoeboxes or clothing purchased online, in new handbags, or other items. Don’t open it — just pop the entire packet in the container and it’ll soak up any moisture to keep your tomato powder dry.
Thank you so much for the information. I planted about 40 tomato plants in my garden and I have a bucket full of ripe tomatoes. I was actually wondering where to sell them coz the market is kind of overflowing with tomatoes. Thank you
I have recipes that use tomato powder in baking—- savory macaroons. I would think you could add it to cheese coins or biscuits as well.
Oh, savory macaroons sound intriguing!
I have been doing this for years. Another thing I use the powder for is to add to breading. I usually bake my breaded stuff, so I can not vouch how good it would it would come out fried. It us great fir breaded and baked fish, pork chops, and especially chicken parm. Also great for simple pasta sauces, or anything you want to add some concentrated umami flavor to. When I make kimchi for a vegan family member, I use homemade pwdered shitake mushrooms, seaweed, and this stuff to get the seafood umami flavor normally achieved with fish sauce and other sea fare.
Aside from having Tomato Paste (which sounds wonderful), why do you have to dry & powder the skins before making them into tomato paste? It seems like its an extra unnecessary step?
Thanks!
You don’t have to if you have a fresh tomato paste recipe you want to use. The instructions I provided are for people who have already dried and powered tomato skins and find themselves wanting to use them in different ways.
