Step 1: Preparing Your Tomatoes

Before you begin the drying process, it’s crucial to prepare your tomatoes properly to ensure they dry evenly and maintain their flavor. Start by selecting fresh, ripe tomatoes—Roma or plum varieties are ideal due to their lower moisture content and firmer flesh.

Begin the preparation by washing your tomatoes thoroughly under cool running water to remove any dirt or residue. This step is important for hygiene and to ensure the quality of your dried tomatoes.

Next, use a sharp knife for slicing. A dull knife can squash the tomatoes and make uneven cuts. On a clean cutting board, carefully slice the tomatoes into uniform pieces, aiming for about ¼ inch in thickness. Consistency in slice thickness is key; it ensures that all the pieces will dry at the same rate. Take your time with this step, as even slices contribute significantly to the success of the drying process.

Step 2: Preparing the Baking Sheets

Proper preparation of your baking sheets is a simple yet vital step in the oven-drying process. It’s all about creating a non-stick surface for the tomatoes and ensuring hassle-free cleanup after drying.

Start by choosing the right size of baking sheets. They should be large enough to accommodate all your tomato slices in a single layer without overcrowding. Overlapping slices will lead to uneven drying.

Next, line your baking sheets with parchment paper or a silicone baking mat. Both options are effective in preventing the tomatoes from sticking to the baking sheet during the drying process.

Parchment paper is a disposable option that makes cleanup quick and straightforward. On the other hand, a silicone baking mat is reusable and environmentally friendly, offering an easy-to-clean surface that can be used repeatedly for various baking and drying needs.

Ensure that the lining covers the entire surface of the baking sheet. This not only prevents sticking but also protects the sheet, preserving its quality and extending its usability. Once lined, your baking sheets are ready for the tomato slices to be placed and dried.

Step 3: Arranging the Tomatoes

Once your tomatoes are sliced and your baking sheets are prepared, the next crucial step is arranging the tomatoes for drying. Begin by placing the tomato slices on the prepared baking sheets. It’s essential to lay them out in a single layer with none of the slices touching or overlapping. This spacing is crucial as it allows for even air circulation around each slice, promoting uniform drying.

If you desire to enhance the flavor of your tomatoes, you can lightly drizzle them with olive oil. Choose a good quality olive oil for this purpose. The oil not only adds a subtle richness to the flavor but also helps in preserving the tomatoes later. Be sure to drizzle it sparingly; too much oil can make the tomatoes greasy and affect the drying process.

Additionally, you can season the slices with salt, which helps in bringing out the natural flavors of the tomatoes. If you’re feeling adventurous, consider adding other herbs and spices such as basil, oregano, thyme, or garlic powder. These can create a variety of flavor profiles, suitable for different culinary uses. Remember, the flavors will intensify as the tomatoes dry, so use seasonings moderately.

Step 4: Oven Drying Process

The oven-drying process is where the magic happens, slowly transforming your fresh tomatoes into rich, flavorful dried pieces. Start by preheating your oven to 200°F (93°C). This low temperature is critical as it allows the tomatoes to dry out slowly without actually cooking them. Higher temperatures might cook the tomatoes, causing them to lose their texture and flavor nuances.

Once the oven is preheated, carefully place the baking sheets inside. If you have multiple sheets, position them on different racks to ensure even heat distribution. However, avoid overcrowding the oven – good air circulation is key for even drying.

How Long to Oven Dry Tomatoes

The drying time for tomatoes can vary significantly based on several factors, including the thickness of your slices, the type of tomato, and individual oven temperature variances. As a general guideline, expect the drying process to take about 3-4 hours. However, it’s advisable to start checking your tomatoes after 2 hours.

During this checking process, look for changes in texture. The goal is to achieve a leathery texture in your tomatoes; they should be pliable but not crispy or brittle. If they are underdone, they’ll feel too soft and might retain moisture, leading to a risk of mold. Over-dried tomatoes, on the other hand, become tough and lose their flavor quality.

Remember, every oven is different, and drying times can vary, so frequent checking is crucial. Adjust the time as needed based on your observations.

Step 5: Cooling and Storing

After your tomatoes have reached the desired level of dryness, the next step is to let them cool and prepare them for storage. This is a crucial stage in preserving their quality and extending their shelf life.


Remove the baking sheets from the oven and set them aside in a safe, heat-resistant area. Allow the tomatoes to cool completely at room temperature. This cooling process is important as it stops the drying process and stabilizes the texture of the tomatoes.

Rushing this step or storing the tomatoes while they are still warm can lead to condensation inside the storage container, which might cause mold or spoilage.


Once the tomatoes are completely cool, it’s time to store them. Choose an airtight container for storage; this could be a zip-lock bag, a glass jar, or a plastic container with a tight-sealing lid. The key is to ensure that no air or moisture can enter the container, as this could compromise the quality of the tomatoes.

Place the cooled tomato slices in the container, taking care not to overcrowd or compress them. If you’re using a bag, gently press out as much air as possible before sealing. Store the container in a cool, dark place like a pantry or cupboard. Properly stored, your oven-dried tomatoes can last for several months, retaining their flavor and texture.

Troubleshooting Tips: How to Oven Dry Fresh Tomatoes

Sometimes, you might encounter issues during the drying process. Here are a couple of tips to help you troubleshoot common problems:

Uneven Drying

If you notice that your tomatoes are drying unevenly, a simple solution is to rotate the baking sheets. Do this approximately every hour. This rotation helps to expose different parts of the tomatoes to the various temperature zones in your oven, promoting more uniform drying.

Too Quick Drying

In some cases, tomatoes may dry out too quickly, which can result in them becoming too brittle or losing flavor. If you observe this, try lowering the oven temperature slightly. Reducing the temperature by 10-15 degrees can slow down the drying process, allowing the tomatoes to dry evenly without over-dehydrating.
