How to Make Homemade Tomato Powder (Without a Dehydrator!)

Homemade Tomato Powder is an ancient anti-waste recipe, created to reuse the outer skin of tomatoes left over from the preparation of tomato puree or peeled tomatoes. In the past, in fact, when tomato preserves were prepared, the scraps were not thrown away, but dried in the sun, crushed and preserved throughout the winter in glass jars, in a similar way to what happens with sun-dried tomatoes in oil.

In our version of homemade tomato powder, the peels are left to dry in the oven, at a low temperature, for about 3 hours. Once cold, they can be flavored with herbs of your choice (in our case oregano and garlic powder) and finally blended: the result is a tasty and incredibly fragrant powder, ideal to use as a spice, therefore to flavor meat and fish, to cream risottos or to give a touch of extra flavor to soups, salads and first courses, but also perfect to use as a natural food coloring for fresh pasta, gnocchi, bread or breadsticks.

What is Tomato Powder?

Tomato powder, a versatile and nutrient-rich ingredient, has roots deeply entwined with the history of tomato preservation. While tomatoes themselves originated in the Americas and were first cultivated by the Aztecs and Mayans, their use spread to Europe in the 16th century following Spanish colonization. Drying and grinding tomatoes into powder became a practical method of preservation, especially in regions like southern Italy, where sun-drying was a traditional practice to extend the fruit's shelf life. This technique allowed tomatoes to be stored without spoilage, maintaining their rich flavor and nutritional value year-round. Over time, tomato powder has gained global popularity, celebrated for its convenience and ability to infuse dishes with intense, concentrated tomato essence.

Pro Tips for The Best Homemade Tomato Powder

• Slice the tomatoes evenly to ensure consistent drying. Thinner slices will dry faster, while thicker slices may retain moisture and take longer.
• Whether using a dehydrator, an oven at low heat, or sun-drying, make sure the tomatoes dry completely to avoid spoilage. Flip them occasionally to promote even drying.
• When using an oven or dehydrator, keep the temperature between 50–60°C (120–140°F) to preserve the natural flavors and nutrients without burning the tomatoes.
• Allow the dried tomato slices to cool completely before grinding. This prevents moisture from accumulating in the powder.
• Keep the tomato powder in an airtight container in a cool, dark place to preserve its flavor and color. Adding a silica gel packet can help absorb any residual moisture.

What Are The Best Tomatoes to Use For Powder?

The best tomatoes for making tomato powder are varieties with low water content and intense flavor, such as Roma, San Marzano, or plum tomatoes. These tomatoes have fewer seeds and thicker flesh, making them ideal for drying and grinding into powder. Opt for fully ripe, firm, and unblemished tomatoes to ensure maximum flavor and quality.

Can I Also Add Other Flavorings to Tomato Powder?

As an alternative to oregano and garlic, you can flavor the tomato powder with chili pepper, paprika or a mix of dried aromatic herbs such as basil, thyme and rosemary; if you prefer, you can leave it natural, making it even more versatile.

What Can You Do With Tomato Powder?

Tomato powder is a versatile ingredient that enhances dishes with rich, concentrated tomato flavor. Use it to make tomato sauce, soups, and stews, or sprinkle it on pizza, pasta, and roasted vegetables. It works as a seasoning for popcorn or chips, a flavor boost in marinades, or a base for dry rubs and spice blends. It’s also great for adding color and taste to bread, dips, and even beverages like Bloody Marys!

Can I Make Tomato Paste or Sauce From Tomato Powder?

Yes, you can use tomato powder to make tomato paste or sauce! For tomato paste, mix tomato powder with a small amount of water to create a thick, concentrated consistency. To make tomato sauce, combine tomato powder with more water, adjusting for your desired thickness, and season with herbs, salt, and spices for extra flavor.

Can This Tomato Powder Be Frozen?

Yes, tomato powder can be frozen to extend its shelf life. Store it in an airtight, freezer-safe container or resealable bag to protect it from moisture and freezer odors. Freezing helps preserve its flavor, color, and freshness for longer periods.

How to Store Tomato Powder

If tightly closed in sterilized glass jars with new caps, tomato powder can be stored for up to 12 months in the pantry, away from sources of light and heat.

How to Make Homemade Tomato Powder

First, wash the tomatoes under running water and dry them with a clean cloth. Then make a cross on the top with the help of a knife.

Blanch the tomatoes in boiling salted water for a couple of minutes, just long enough for the peel to start peeling off. Once cool, separate the peel from the pulp, setting aside the latter, which can be used to prepare sauces and gravies.

Rinse the peels to remove any residue, dry them thoroughly to eliminate the vegetation water and finally arrange them on a baking tray, covered with parchment paper, well spaced apart.

Add salt and let them dry in a static oven at 170°F/80°C for about 3 hours, turning them often. You will know when they're ready because they will be completely dry and slightly curled: take them out of the oven and let them cool completely.

Once they are completely cold, transfer the peels into a glass jar and season with the garlic powder.

Add the oregano.

At this point, blend until you obtain a more or less fine powder, depending on your tastes.

Your homemade tomato powder is ready to be used!
