Tomatoes are a garden treasure, and for those who have experienced the joy of a bumper crop, the question of how to preserve them often arises. While many turn to canning or freezing, there’s a lesser-known method that allows you to preserve tomatoes for an astonishing two years without the use of any additional ingredients—just your trusty oven. In this article, we’ll embark on a culinary adventure to discover how you can achieve this remarkable feat of tomato preservation.

The Oven-Drying Technique:

Oven-drying tomatoes is an ancient preservation method that removes moisture from the fruit, preventing bacterial growth and spoilage. With careful preparation and patience, you can enjoy the vibrant flavors of your homegrown tomatoes for an extended period.

Ingredients and Equipment:

  • Ripe Tomatoes
  • Olive Oil (Optional)
  • Salt (Optional)
  • Baking Sheets
  • Parchment Paper
  • A Sharp Knife
  • A Cooling Rack

Step-by-Step Guide:

1. Select the Finest Tomatoes:

  • Begin with ripe, high-quality tomatoes from your garden or local market. Choose varieties known for their rich flavor.

2. Preheat Your Oven:

  • Preheat your oven to the lowest setting, typically around 150-200°F (65-95°C).

3. Slice the Tomatoes:

  • Wash and slice the tomatoes into 1/4-inch thick rounds. Removing the seeds is optional.

4. Arrange on Baking Sheets:

  • Line baking sheets with parchment paper for easy removal and cleanup.
  • Place the tomato slices on the sheets in a single layer, ensuring they do not touch.

5. Optional Seasoning:

  • Drizzle olive oil over the tomato slices for added flavor and preservation. A sprinkle of salt is optional.

6. Slow and Steady Drying:

  • Place the baking sheets in the preheated oven.
  • The slow drying process can take anywhere from 6 to 12 hours, depending on your oven’s temperature and humidity levels. Patience is key.

7. Check for Desired Consistency:

  • The tomatoes are ready when they are dry but still pliable. They should not be crispy.

8. Cool and Store:

  • Remove the dried tomato slices from the oven and allow them to cool on a wire rack.
  • Once completely cool, store them in airtight containers or vacuum-sealed bags.

Tips for Long-Term Storage:

  • Store your oven-dried tomatoes in a cool, dark, and dry place to prevent moisture absorption.
  • Check for any signs of moisture or spoilage during storage and discard affected pieces.
  • Use your oven-dried tomatoes in a variety of dishes, from pasta and salads to sandwiches and pizzas.


Oven-drying tomatoes is not only a practical method of preserving your tomato harvest but also a delightful culinary experience. As you savor the intense flavors of your oven-dried tomatoes, you’ll appreciate the fruits of your labor and the ability to enjoy your homegrown tomatoes for up to two years.
