Benefits of Dehydrating Tomato Skins


1. Nutrient-Rich: Tomato skins are packed with vitamins A and C, potassium, and fiber. Dehydrating them preserves these nutrients, making them a healthy addition to your diet.


2. Zero-Waste: Dehydrating tomato skins is an excellent way to use every part of the tomato, reducing food waste and making the most of your garden’s bounty.


3. Flavor Enhancer: Dried tomato skins can be ground into a powder and used to add a rich, umami flavor to soups, stews, sauces, and even bread.


4. Easy Storage: Dehydrated tomato skins have a long shelf life and require minimal storage space, making them a convenient pantry staple.


Step-by-Step Guide to Dehydrating Tomato Skins


Step 1: Prepare the Tomato Skins

After peeling tomatoes for canning or cooking, save the skins and spread them out on a clean kitchen towel to remove excess moisture. You can use skins from any variety of tomatoes, but make sure they are clean and free of blemishes.


Step 2: Arrange on Dehydrator Trays

Place the tomato skins in a single layer on dehydrator trays. If you don’t have a dehydrator, you can use a baking sheet lined with parchment paper in your oven. Make sure the skins are not overlapping to ensure even drying.


Step 3: Dehydrate

Set your dehydrator to 135°F (57°C) and dry the tomato skins for 8-12 hours, or until they are completely dry and brittle. If using an oven, set it to the lowest temperature possible and check the skins every few hours until they are fully dehydrated.


Step 4: Cool and Store

Once dried, allow the tomato skins to cool completely. Store them in an airtight container in a cool, dark place. Properly stored, they can last for up to a year.


Step 5: Grind into Powder (Optional)

For a versatile seasoning, grind the dried tomato skins into a fine powder using a spice grinder or blender. Tomato skin powder can be used to add flavor to a variety of dishes, from soups and sauces to homemade bread and pasta.
