Methods of Dehydrating Tomato Slices
There are several methods of dehydrating tomato slices, including using a food dehydrator, oven, and sun drying.
Using a Food Dehydrator
A food dehydrator is a specialized appliance that is designed specifically for dehydrating foods. It works by circulating hot air around the food, which helps to remove the water content.
- Temperature: Set the temperature to 135°F – 140°F (57°C – 60°C).
- Time: Dehydrate for 6-8 hours, or until the tomato slices reach your desired level of dryness.
- Trays: Place the tomato slices in a single layer on the dehydrator trays.
Using an Oven
If you don’t have a food dehydrator, you can also use your oven to dehydrate tomato slices.
- Temperature: Set the temperature to its lowest setting (usually around 150°F – 200°F or 65°C – 90°C).
- Time: Dehydrate for 3-4 hours, or until the tomato slices reach your desired level of dryness.
- Trays: Place the tomato slices in a single layer on baking sheets.
Sun Drying
Sun drying is a simple and cost-effective way to dehydrate tomato slices.
- Temperature: Place the tomato slices in direct sunlight, ideally in a warm and dry location.
- Time: Dehydrate for 2-3 days, or until the tomato slices reach your desired level of dryness.
- Trays: Place the tomato slices in a single layer on wire racks or paper towels.

Freezer Storage
- Freezer bags: Store the dehydrated tomato slices in freezer bags, such as Ziploc bags.
- Freezer containers: Store the dehydrated tomato slices in airtight freezer containers, such as plastic containers.
Rehydrating Dehydrated Tomato Slices
To rehydrate your dehydrated tomato slices, simply soak them in water or broth.
Water Rehydration
- Water: Soak the dehydrated tomato slices in water for around 30 minutes, or until they reach your desired level of rehydration.
Broth Rehydration
- Broth: Soak the dehydrated tomato slices in broth for around 30 minutes, or until they reach your desired level of rehydration.
In conclusion, dehydrating tomato slices is a simple and effective way to preserve the flavor and nutritional value of fresh tomatoes. By following the methods outlined in this article, you can enjoy your tomatoes throughout the year.
What are the benefits of dehydrating tomato slices?
Dehydrating tomato slices is a great way to preserve the freshness and flavor of tomatoes for a longer period.

What equipment do I need to dehydrate tomato slices?
To dehydrate tomato slices, you will need a few basic pieces of equipment. A food dehydrator is the most common and efficient way to dehydrate tomatoes. However, if you don’t have a dehydrator, you can also use your oven on the lowest temperature setting or even the sun to dry the tomatoes.
In addition to a dehydrator or oven, you will also need some basic kitchen tools such as a cutting board, knife, and tray or sheet pan. You may also want to use parchment paper or a silicone mat to line the tray and prevent the tomatoes from sticking.
How do I prepare tomato slices for dehydrating?
To prepare tomato slices for dehydrating, start by washing and drying the tomatoes thoroughly. Remove any stems or leaves, and slice the tomatoes into thin, uniform pieces. You can slice the tomatoes by hand or use a mandoline or food slicer for more precise slices.
Next, remove any excess moisture from the tomato slices by gently patting them dry with a paper towel. This will help the tomatoes to dry more evenly and prevent them from sticking together. You can also sprinkle the tomato slices with salt or other seasonings before dehydrating for added flavor.
What is the ideal temperature and time for dehydrating tomato slices?
The ideal temperature and time for dehydrating tomato slices will depend on the equipment you are using and the desired level of dryness. Generally, a temperature of 135-140°F (57-60°C) is recommended for dehydrating tomatoes. If using a dehydrator, you can set the temperature and timer according to the manufacturer’s instructions.
If using your oven, set the temperature to the lowest setting (usually around 150-200°F or 65-90°C) and dehydrate the tomatoes for 6-12 hours. You can also check on the tomatoes periodically to ensure they are not overdrying. The ideal dryness level will depend on your personal preference, but generally, dehydrated tomato slices should be flexible and slightly chewy.
How do I store dehydrated tomato slices?
