Dehydrating tomatoes is a fantastic way to preserve the summer’s bounty, concentrating their flavor into a sweet, tangy treat perfect for snacking, adding to soups, stews, sauces, and so much more. But before you load up your dehydrator, a crucial question arises: Should you peel your tomatoes before dehydrating them? The answer isn’t a simple yes or no. It depends on several factors, including your personal preferences, the type of tomato you’re using, and the final product you envision. Let’s dive into the peeling debate and explore the pros and cons of each approach.
The Case for Peeling Tomatoes Before Dehydrating
Peeling tomatoes before dehydrating offers several potential benefits, primarily concerning texture and ease of use in certain recipes. The skin of a tomato, while perfectly edible, can become tough and leathery when dehydrated. This toughness can be particularly noticeable when using larger tomato varieties or if you plan to use your dehydrated tomatoes in sauces or other dishes where a smooth consistency is desired.
Improved Texture
The most significant advantage of peeling is the resulting texture. Without the skin, the dehydrated tomato pieces are generally smoother and more pliable. This is especially important if you’re aiming for a gourmet product or plan to grind the dehydrated tomatoes into a powder for use as a seasoning. A smoother texture translates to a more pleasant eating experience, especially for those who find the chewy skin of unpeeled dehydrated tomatoes unappealing. The rehydrated peel, depending on the type of tomato and how you are using it, can take longer to soften than the flesh.
Easier Blending and Grinding
If you intend to use your dehydrated tomatoes in sauces, soups, or as a powder, peeling them beforehand makes the process significantly easier. The skin can be difficult to blend smoothly, potentially leaving small, noticeable pieces in your final product. Removing the skin ensures a silky-smooth consistency, creating a more refined and professional result. This is especially important for commercial applications or when aiming for a specific texture in your culinary creations.
Visual Appeal
While arguably less important than texture, peeled tomatoes tend to have a more consistent and appealing appearance after dehydration. The skin can sometimes wrinkle and separate during the drying process, leading to an uneven and less aesthetically pleasing final product. Peeling eliminates this issue, resulting in a more uniform and visually attractive dehydrated tomato.
The Argument Against Peeling: Leaving the Skins On
While peeling tomatoes may seem like the obvious choice, there are compelling reasons to leave the skins on before dehydrating. These reasons range from nutritional benefits to convenience and even flavor enhancement.
Nutritional Value
Tomato skins are a rich source of nutrients, including lycopene, a powerful antioxidant linked to various health benefits. By removing the skin, you’re essentially discarding a significant portion of the tomato’s nutritional value. Leaving the skin on allows you to retain these beneficial compounds, making your dehydrated tomatoes a healthier snack or ingredient.
Increased Fiber Content
The skin also contributes to the overall fiber content of the tomato. Fiber is essential for digestive health and can help regulate blood sugar levels. Dehydrating the tomatoes with the skins intact provides a valuable source of dietary fiber, adding another nutritional benefit to your preserved product.
Enhanced Flavor
Some believe that the skin of the tomato contributes to its overall flavor profile. While the flesh is sweet and juicy, the skin can add a slightly tangy or earthy note that complements the sweetness. Leaving the skin on can result in a more complex and nuanced flavor in your dehydrated tomatoes.
Time and Effort
Peeling tomatoes can be a time-consuming and tedious process, especially when dealing with large quantities. Leaving the skins on saves you valuable time and effort, allowing you to focus on other aspects of the dehydration process. This can be a significant factor for those who are dehydrating large batches of tomatoes for preservation purposes.
Factors to Consider Before Making Your Decision
Ultimately, the decision of whether or not to peel your tomatoes before dehydrating depends on several factors. Carefully consider these points to determine the best approach for your specific needs and preferences.
Tomato Variety
The type of tomato you’re using can significantly influence the outcome of the dehydration process, and therefore, your decision to peel or not. Some varieties, like Roma tomatoes, have thinner skins that tend to dehydrate well and don’t become overly tough. Other varieties, particularly larger heirloom tomatoes, may have thicker skins that are more prone to becoming leathery. For thicker-skinned varieties, peeling might be the preferred option.
Intended Use
How you plan to use your dehydrated tomatoes is a crucial factor in determining whether or not to peel them. If you plan to use them in sauces or soups where a smooth consistency is essential, peeling is likely the best choice. If you intend to use them as a snack or in dishes where a slightly chewy texture is acceptable, leaving the skins on might be perfectly fine.
Personal Preference
Ultimately, the decision boils down to personal preference. Some people simply dislike the texture of dehydrated tomato skins, regardless of the variety or intended use. Others appreciate the added flavor and nutritional benefits that the skins provide. Experiment with both peeled and unpeeled tomatoes to determine which you prefer.
Time Constraints
If you’re short on time, leaving the skins on is the more practical option. Peeling tomatoes can add a significant amount of time to the dehydration process, especially if you’re working with a large batch.
Methods for Peeling Tomatoes
If you decide that peeling is the right choice for you, there are several methods you can use to easily remove the skins from your tomatoes.
Blanching
Blanching is a common and effective method for peeling tomatoes. Here’s how:
- Bring a large pot of water to a boil.
- Score the bottom of each tomato with an “X” using a sharp knife.
- Carefully drop the tomatoes into the boiling water for 30-60 seconds, or until the skin begins to peel back.
- Immediately transfer the tomatoes to an ice bath to stop the cooking process.
- Once cooled, the skins should easily slip off with your fingers or a paring knife.
Roasting
Roasting tomatoes can also make peeling easier. Roasting brings out the natural sweetness of the tomato as well.
- Preheat your oven to 400°F (200°C).
- Cut the tomatoes in half.
- Place the tomatoes cut-side up on a baking sheet.
- Roast for 20-30 minutes, or until the skins begin to blister and separate.
- Let cool slightly, then peel off the skins with your fingers or a paring knife.
Tips for Dehydrating Tomatoes Successfully
Regardless of whether you choose to peel your tomatoes or not, here are some tips to ensure a successful dehydration process.
Choose Ripe Tomatoes
Select ripe, firm tomatoes for the best flavor and texture. Overripe tomatoes may become mushy during dehydration.
Slice Evenly
Slice the tomatoes into even pieces to ensure consistent drying. Unevenly sliced tomatoes will dry at different rates, leading to some pieces being over-dried while others are still moist.
Consider Pre-Treating
Some people like to pre-treat their tomatoes with a light coating of salt or herbs before dehydrating. This can help to enhance the flavor and preserve the color.
Monitor the Drying Process
Keep a close eye on the tomatoes during the dehydration process and adjust the temperature and drying time as needed. The ideal drying temperature is typically between 135°F (57°C) and 145°F (63°C).
Store Properly
Once the tomatoes are fully dehydrated, store them in an airtight container in a cool, dark place. Properly stored dehydrated tomatoes can last for several months or even years.
Experiment and Enjoy
The best way to determine whether you prefer peeled or unpeeled dehydrated tomatoes is to experiment and see for yourself. Try dehydrating both peeled and unpeeled tomatoes and compare the results. Pay attention to the texture, flavor, and overall appearance of each batch. Don’t be afraid to experiment with different tomato varieties and pre-treatment options to find what works best for your taste. Dehydrating tomatoes is a rewarding process that allows you to enjoy the flavors of summer all year round. Whether you choose to peel or not, the most important thing is to have fun and enjoy the delicious results.
Dehydrated Tomato Applications
Once you have your dehydrated tomatoes, the possibilities are truly endless. Here are just a few ideas to get you started.
- Snacking: Dehydrated tomatoes make a delicious and healthy snack.

Dehydrating tomatoes is a rewarding and versatile way to preserve the flavors of summer. By carefully considering the factors outlined in this article, you can make an informed decision about whether to peel your tomatoes or not and create delicious, long-lasting treats that you can enjoy all year round.
Is it necessary to peel tomatoes before dehydrating them?
No, peeling tomatoes before dehydrating is not strictly necessary. Many people choose to dehydrate tomatoes with the skins on, as the skins provide additional nutrients and fiber. The skins also help the tomato halves retain their shape better during the drying process, preventing them from becoming overly thin and brittle. However, some people find the skins tough or prefer the texture of peeled tomatoes, especially when rehydrating and using them in sauces or other dishes.
Ultimately, the decision to peel or not to peel is a matter of personal preference. If you dislike the texture of tomato skins, particularly after drying, peeling is recommended. If you’re looking for extra nutrients and a slightly firmer texture, leaving the skins on is perfectly acceptable. Consider the intended use of the dried tomatoes when making your decision.
Does peeling affect the drying time of tomatoes?
Yes, peeling tomatoes can slightly reduce the drying time. The skin acts as a barrier, slowing down the evaporation of moisture from the tomato flesh. When the skin is removed, the moisture can escape more easily, leading to a faster drying process. This difference in drying time is usually not dramatic, but it can be noticeable, especially when dehydrating large batches of tomatoes.
However, the difference in drying time isn’t significant enough to make peeling a mandatory step solely for the purpose of speeding up dehydration. Factors like humidity, the thickness of the tomato slices, and the temperature of the dehydrator will have a much larger impact on the overall drying time. So, focus on consistent slicing and proper dehydrator settings for optimal results.
What is the easiest way to peel tomatoes for dehydrating?
The blanching method is widely considered the easiest and most efficient way to peel tomatoes. Start by bringing a pot of water to a rolling boil. While the water is heating, use a paring knife to score an “X” on the bottom of each tomato. This helps the skin to easily peel away after blanching. Prepare a bowl of ice water.
Carefully lower the tomatoes into the boiling water for 30-60 seconds, or until the skins start to loosen around the scored “X”. Immediately transfer the tomatoes to the ice water bath to stop the cooking process. Once cooled, the skins should easily peel off with your fingers or a paring knife.
What types of tomatoes are best for dehydrating?
Roma or plum tomatoes are generally considered the best varieties for dehydrating. They have a meaty texture, fewer seeds, and lower water content compared to other types of tomatoes. This makes them ideal for drying as they result in a more concentrated flavor and texture. Their firm flesh also holds up well during the dehydration process.
However, you can dehydrate almost any type of tomato. Cherry and grape tomatoes are also popular choices, as they are easy to prepare and dry quickly. Larger varieties, like beefsteak tomatoes, can be dehydrated, but they have a higher water content and may require a longer drying time. Experiment with different varieties to find your personal favorite.
How thinly should I slice tomatoes for dehydrating?
The ideal thickness for slicing tomatoes for dehydrating is around ¼ to ½ inch. This thickness provides a good balance between drying time and the final texture of the dehydrated tomatoes. Slices that are too thin may become brittle and papery, while slices that are too thick may take significantly longer to dry and may not dry completely in the center.
Adjust the thickness slightly based on the type of tomato you’re using. For smaller tomatoes like cherry or grape tomatoes, you can simply cut them in half. For larger, more watery tomatoes, consider slicing them slightly thicker to prevent them from becoming too thin and fragile during the drying process. Consistency in slice thickness is crucial for even drying.
How do I know when my dehydrated tomatoes are done?
Dehydrated tomatoes are done when they are leathery and slightly pliable but not sticky. They should be significantly reduced in size and weight. When you squeeze a piece, no moisture should be expressed. The texture should be similar to that of dried fruit. If they are still moist, they need to be dried for a longer period.
Allow a piece to cool completely before testing for doneness. Warm tomatoes can feel softer than they actually are. If you’re unsure, it’s better to err on the side of over-drying rather than under-drying, as under-dried tomatoes can mold during storage. A properly dried tomato will feel firm but still flexible, and will not feel wet or sticky to the touch.
How should I store dehydrated tomatoes to maximize their shelf life?
Proper storage is essential for extending the shelf life of dehydrated tomatoes. Once the tomatoes are completely cooled, store them in an airtight container, such as a glass jar or a resealable plastic bag. Make sure the container is completely dry to prevent any moisture from rehydrating the tomatoes and causing mold growth.
Store the container in a cool, dark, and dry place, away from direct sunlight and heat. A pantry or cupboard is ideal. Properly stored dehydrated tomatoes can last for 6-12 months. For even longer storage, consider vacuum sealing the tomatoes or storing them in the freezer, where they can last for several years. Check periodically for any signs of moisture or mold, and discard any affected tomatoes.
