Sun-dried tomatoes: their intense, concentrated flavor adds a burst of sunshine to any dish. Whether you’re tossing them into pasta, blending them into pesto, or simply snacking on them straight from the jar, they’re a culinary powerhouse. But store-bought sun-dried tomatoes can be expensive, and sometimes lack the vibrant taste you crave. The solution? Make your own! Drying tomatoes at home is surprisingly easy, and the results are infinitely more flavorful than anything you’ll find on a supermarket shelf. Plus, you get the satisfaction of knowing exactly what went into them.
Understanding the Magic of Sun-Drying
Sun-drying isn’t just about leaving tomatoes out in the sun and hoping for the best. It’s a process that concentrates the tomato’s natural sugars and acids, intensifying its flavor and creating a wonderfully chewy texture. The sun’s heat evaporates the water content, which inhibits microbial growth and preserves the tomatoes. The result is a shelf-stable ingredient packed with umami.
The key to successful sun-drying lies in controlling the temperature and humidity. You need enough heat to dry the tomatoes quickly and evenly, but not so much that they burn or become leathery. Low humidity is also crucial, as it allows the moisture to escape more easily. That’s why sun-dried tomatoes are traditionally made in regions with hot, dry climates. However, even if you don’t live in such a place, you can still achieve excellent results with a little ingenuity.
Choosing the Right Tomatoes
The type of tomato you choose will significantly impact the final product. Roma tomatoes are the most popular choice for sun-drying because they have a meaty texture, relatively few seeds, and a good balance of sweetness and acidity. Other good options include San Marzano and other paste-type tomatoes.
Avoid using overly juicy tomatoes like beefsteak or heirloom varieties, as they will take much longer to dry and may not have the same concentrated flavor. Look for tomatoes that are ripe but firm, without any blemishes or soft spots. Overripe tomatoes will be mushy and difficult to work with.
Prepping Your Tomatoes for Drying
Proper preparation is essential for achieving evenly dried tomatoes. This step involves washing, coring, and halving or quartering the tomatoes, depending on their size.
Start by thoroughly washing the tomatoes under cool running water. Remove any stems or leaves. Next, core each tomato by cutting out the tough white core at the stem end. Now, depending on the size of your tomatoes, you can either halve them lengthwise or quarter them. Smaller Roma tomatoes can simply be halved, while larger tomatoes should be quartered to ensure they dry properly.
If desired, you can remove the seeds from the tomatoes, although this isn’t strictly necessary. Removing the seeds will speed up the drying process and result in a slightly chewier texture. To remove the seeds, gently squeeze each tomato half or quarter over a bowl to dislodge the seeds and pulp.
Methods for Sun-Drying Tomatoes
While the name suggests relying solely on the sun, you can achieve fantastic sun-dried tomatoes using a variety of methods, depending on your climate and equipment. Each method has its advantages and disadvantages.
Traditional Sun-Drying: A Labor of Love
This is the most authentic method, but it requires a hot, dry climate and plenty of patience. If you live in a sunny, low-humidity area with daytime temperatures consistently above 85°F (29°C), you can try sun-drying your tomatoes outdoors.
To sun-dry tomatoes, arrange the prepared tomato halves or quarters, cut-side up, on a wire rack or a clean screen. Make sure the tomatoes are not touching each other, to allow for good air circulation. Sprinkle the tomatoes lightly with salt, which helps to draw out moisture.
Cover the tomatoes with cheesecloth or netting to protect them from insects and birds. Place the rack in a sunny, well-ventilated spot. Bring the tomatoes indoors at night or if it rains.
The drying process can take anywhere from 3 to 7 days, depending on the weather conditions. The tomatoes are ready when they are leathery and pliable, with a slightly shriveled appearance. They should still have some moisture in them, but not be wet or sticky.
Oven-Drying: A Reliable Alternative
If you don’t have the right climate for traditional sun-drying, oven-drying is an excellent alternative. It’s more reliable and faster, and you have more control over the temperature.
Preheat your oven to the lowest possible setting, ideally around 200°F (93°C). If your oven doesn’t go that low, prop the door open slightly to allow some heat to escape.
Arrange the prepared tomato halves or quarters, cut-side up, on a baking sheet lined with parchment paper. Sprinkle the tomatoes lightly with salt.
Place the baking sheet in the oven and dry the tomatoes for 6 to 12 hours, or until they are leathery and pliable. The drying time will depend on the size of the tomatoes and the temperature of your oven. Check the tomatoes periodically and rotate the baking sheet to ensure even drying.
Dehydrator Drying: Precision and Control
Using a food dehydrator is perhaps the easiest and most consistent method for drying tomatoes. Dehydrators provide a controlled environment with consistent temperature and airflow, resulting in evenly dried tomatoes every time.
Arrange the prepared tomato halves or quarters, cut-side up, on the dehydrator trays. Make sure the tomatoes are not touching each other. Sprinkle the tomatoes lightly with salt.
Set the dehydrator to 135°F (57°C) and dry the tomatoes for 6 to 12 hours, or until they are leathery and pliable. The drying time will depend on the size of the tomatoes and the model of your dehydrator. Check the tomatoes periodically and rotate the trays to ensure even drying.
Enhancing the Flavor: Herbs and Spices
While salt is essential for drawing out moisture and preserving the tomatoes, you can also add other herbs and spices to enhance their flavor. These additions should be subtle, allowing the natural tomato flavor to shine through.
Some popular choices include:
- Dried oregano: A classic Mediterranean herb that complements tomatoes perfectly.
- Dried basil: Adds a sweet and aromatic note.
- Garlic powder: Provides a savory depth.
- Red pepper flakes: Adds a touch of heat.
- Freshly ground black pepper: Enhances the overall flavor.
Sprinkle the herbs and spices over the tomatoes along with the salt before drying. You can also add a drizzle of olive oil for extra flavor and richness.
Storing Your Homemade Sun-Dried Tomatoes
Proper storage is crucial for preserving the flavor and quality of your homemade sun-dried tomatoes. There are several ways to store them, depending on how long you want to keep them.
Dry Storage
Once the tomatoes are fully dried, you can store them in an airtight container at room temperature for several months. Make sure the tomatoes are completely dry to prevent mold growth. It’s best to keep them in a cool, dark place.
Oil-Packed Storage
Packing sun-dried tomatoes in olive oil is a delicious way to preserve them and infuse them with even more flavor. This method is particularly good for tomatoes that are not completely dry, as the oil helps to prevent spoilage.
To pack sun-dried tomatoes in oil, place the dried tomatoes in a clean jar. Add any desired herbs and spices, such as garlic cloves, rosemary sprigs, or bay leaves. Pour olive oil over the tomatoes until they are completely submerged.
Make sure to remove any air bubbles by pressing down on the tomatoes with a spoon. Seal the jar tightly and store it in the refrigerator for up to several months. The oil may solidify in the refrigerator, but it will return to its liquid state at room temperature.
It’s important to note that oil-packed sun-dried tomatoes should always be stored in the refrigerator, as they can harbor bacteria at room temperature.
Freezing
Sun-dried tomatoes can also be frozen for longer storage. Spread the dried tomatoes in a single layer on a baking sheet and freeze them until solid. Then, transfer them to a freezer bag or container.
Frozen sun-dried tomatoes can be stored for up to a year. You can use them directly from the freezer without thawing.
Rehydrating Sun-Dried Tomatoes
While sun-dried tomatoes can be enjoyed as is, they can also be rehydrated to soften their texture and intensify their flavor even further.
To rehydrate sun-dried tomatoes, place them in a bowl and cover them with hot water or olive oil. Let them soak for 30 minutes to an hour, or until they are soft and pliable.
You can then drain the tomatoes and use them in your favorite recipes. The soaking liquid can also be used as a flavorful addition to sauces, soups, and stews.
Culinary Uses for Sun-Dried Tomatoes
Sun-dried tomatoes are incredibly versatile and can be used in a wide variety of dishes. Their intense flavor adds depth and complexity to everything from pasta sauces to salads.
Here are just a few ideas for using your homemade sun-dried tomatoes:

What type of tomatoes work best for sun-drying?
The best tomatoes for sun-drying are those with thick walls, meaty flesh, and lower water content. Roma or plum tomatoes are ideal choices due to their elongated shape, robust flavor, and ability to hold their shape during the drying process. Larger, juicier tomatoes like beefsteak varieties can be used, but they will require more time and effort to dry properly, and the end result may be less concentrated in flavor.
Avoid tomatoes that are overly ripe or bruised, as these can spoil during the drying process. Choose firm, ripe tomatoes that are free from blemishes and have a deep red color. Experimenting with different varieties can lead to interesting flavor profiles, but sticking to Roma or plum tomatoes is a safe bet for consistent and delicious results.
How long does it take to sun-dry tomatoes at home?
The time it takes to sun-dry tomatoes depends heavily on factors such as the weather, humidity, and the size of the tomato pieces. Under optimal conditions – hot, sunny days with low humidity – it can take anywhere from 2 to 5 days for tomatoes to dry properly using the traditional method. Check the tomatoes daily and bring them indoors if rain or dew is expected.
If you’re using a dehydrator, the drying time can be significantly reduced, typically ranging from 6 to 12 hours, depending on the dehydrator’s settings and the tomato size. An oven can also be used at a low temperature (around 200°F or 93°C), which usually takes 3 to 4 hours. Regardless of the method, the goal is to remove most of the moisture without burning the tomatoes, resulting in a leathery texture and intensified flavor.
What’s the best way to store homemade sun-dried tomatoes?
Proper storage is crucial to preserve the quality and prevent spoilage of your homemade sun-dried tomatoes. The most common method is to pack them in olive oil, ensuring they are completely submerged. Add herbs like rosemary, thyme, or garlic cloves to the oil for extra flavor. Store the jar in the refrigerator, where they can last for several months.
Alternatively, you can store dried tomatoes in an airtight container in a cool, dark, and dry place. They will keep for several weeks in this manner, although their texture might become slightly tougher. To rehydrate them before use, simply soak them in warm water or olive oil for about 30 minutes. Freezing is also an option. Spread the dried tomatoes on a baking sheet and freeze them individually before transferring them to a freezer bag. They can then be used directly from the freezer, though freezing might slightly alter their texture.
Do I need to blanch the tomatoes before sun-drying them?
Blanching tomatoes before sun-drying is generally not necessary, but it can help loosen the skins and make them easier to peel if you prefer a smoother final product. Some people find the skins can become tough during the drying process, so removing them beforehand can improve the texture.
However, skipping the blanching step saves time and effort, and the skins are perfectly edible. If you choose to blanch, simply immerse the tomatoes in boiling water for about 30-60 seconds, then immediately transfer them to an ice bath. The skins should then slip off easily. Whether or not to blanch is largely a matter of personal preference.
How do I prevent mold from growing on my sun-drying tomatoes?
Preventing mold growth is essential for producing safe and delicious sun-dried tomatoes. Proper drying is the key. Ensure the tomatoes are thinly sliced or halved to allow for even drying. Position them on a drying rack or baking sheet with adequate spacing for air circulation. If drying outdoors, choose a sunny location with good airflow and protect them from insects with a mesh cover.
Regularly check the tomatoes during the drying process and remove any that show signs of mold or discoloration. If you live in a humid climate, consider using a dehydrator or oven instead of sun-drying, as these methods provide more control over the drying environment. Make sure the tomatoes are thoroughly dried before storing them to minimize the risk of mold growth.
What are some creative ways to use homemade sun-dried tomatoes?
Homemade sun-dried tomatoes are incredibly versatile and can add a burst of flavor to a wide range of dishes. They are delicious in pasta sauces, pesto, salads, and sandwiches. Chop them up and add them to bread dough for a savory twist, or incorporate them into quiches and frittatas for added depth of flavor.
Beyond the usual applications, try blending them into dips and spreads, such as hummus or tapenade. They can also be used to infuse olive oil with their rich, concentrated flavor. Consider adding them to stews and soups for a hint of sweetness and umami. The possibilities are truly endless, and their intense flavor will elevate any dish.
Can I add salt and herbs while sun-drying my tomatoes?
Yes, adding salt and herbs during the sun-drying process is a great way to enhance the flavor of your homemade sun-dried tomatoes. Sprinkling the tomatoes with salt before drying helps draw out moisture, which speeds up the drying process and concentrates the flavors.
