Dehydrating Tomatoes: Air Fryer Magic

Yes, you can dehydrate tomatoes in an air fryer. This is a great way to preserve your tomatoes and create a sweet, concentrated flavour. The process is simple and can be done in a few easy steps. You can use any type of tomato, but the cooking time will vary depending on the size and juiciness of the tomato. The air fryer is an excellent alternative to sun-drying, especially if you live in a place with limited sunshine.

How to cut tomatoes for air frying

There are several ways to cut tomatoes for air frying, and the method you choose will depend on the type of tomatoes you are using and the desired outcome. Here is a detailed guide on how to cut tomatoes for air frying:

Cherry tomatoes or grape tomatoes:

Cherry and grape tomatoes are small and can be air-fried whole. However, if you want to cut them, you can halve or quarter them. Cutting them will reduce the cooking time, so keep an eye on them to avoid overcooking.

Medium-sized tomatoes:

For medium-sized tomatoes, cut each tomato into two pieces. You can then remove the inner part of the tomato, or keep it in for a juicier result.

Large tomatoes:

For larger tomatoes, such as Roma or beefsteak tomatoes, it is recommended to cut them into smaller pieces before air frying. You can cut them into slices, halves, or quarters, depending on your preference. Larger pieces may take longer to cook, so adjust your cooking time accordingly.

Plum tomatoes:

Plum tomatoes are smaller in size, but you may still want to cut them before air frying. Cutting them in half or quarters will help speed up the drying process.

Green tomatoes:

Green tomatoes can be air-fried as well. You can cut them into slices or wedges, depending on their size and your preference.

Heirloom tomatoes:

Heirloom tomatoes come in various sizes, so the cutting method will depend on their size. You can cut them into slices, halves, or quarters.

Once you have cut your tomatoes to the desired size, you can proceed with your air fryer recipe. Remember to adjust the cooking time based on the size and type of tomatoes you are using.

Air fryer temperature and time settings

To dehydrate tomatoes in an air fryer, the temperature and timing will depend on the type of tomatoes you are using and the desired level of dehydration.

For smaller tomatoes, such as cherry, grape, or Campari tomatoes, an air fryer temperature of 240°F (115°C) is recommended. For these varieties, the cooking time can range from 45 minutes to 1 hour and 15 minutes. It is important to check on the tomatoes every 10 minutes or so to ensure they do not get too dried out or burned.

For larger tomatoes, such as heirloom, on-the-vine, or Roma tomatoes, a lower temperature setting of 190°F (88°C) is suggested, with a cooking time of around 3 hours. Again, it is important to periodically check on the tomatoes and adjust the time as needed, depending on their moisture content and thickness.

If you are aiming for a smoky char on the outside of the tomatoes, you can increase the temperature to 390°F (200°C) for the final 5-6 minutes of cooking time. This step should be carefully monitored, as the tomatoes will char very quickly at this high temperature.

The ideal temperature and time settings for dehydrating tomatoes in an air fryer can vary depending on the specific model of the appliance and personal preferences for the final texture of the tomatoes. It is always a good idea to refer to the manufacturer's instructions for your particular air fryer model and to experiment with different settings to find the optimal combination for your desired results.

Storing dehydrated tomatoes

Firstly, it is important to let the dehydrated tomatoes cool completely before storing them. Then, decide on your storage method. There are several options, including airtight containers, freezer bags, or glass jars. If using a glass jar, you can cover the tomatoes with olive oil and seal the jar tightly. This method allows the tomatoes to be stored at room temperature for several months. However, if you choose not to store them in olive oil, they will need to be soaked in water for an hour or two before use. Alternatively, you can store dehydrated tomatoes in airtight containers or freezer bags in a cool, dark place. Be sure to press out as much air from the bags as possible, and use them within 6 to 9 months for the best quality.

Another option is to freeze dehydrated tomatoes. Before doing so, spread them on a baking sheet and place them in the freezer for about 2 hours. Then, transfer the frozen tomatoes to a freezer-safe bag or container. They can be stored in the freezer for at least a year.

Regardless of the storage method, it is important to ensure that the tomatoes are completely dry before storing them. This helps prevent spoilage and the growth of bacteria. Additionally, if you notice any condensation in the storage container during the first week, return the tomatoes to the oven or dehydrator to dry further.

By following these simple steps, you can enjoy your dehydrated tomatoes for many months!

Rehydrating dehydrated tomatoes

The next step is to prepare the tomatoes for rehydration. Place the desired amount of dehydrated tomatoes in a heatproof bowl and cover them with the chosen rehydration liquid. For saltwater, dissolve 3/4 teaspoon of salt in 1.5 cups of warm tap water. For broth, use 1 cup of broth for every 1/2 cup of tomatoes.

Once the tomatoes are covered in liquid, microwave the bowl for 2 minutes. After microwaving, let the tomatoes sit in the liquid until the skin side can be pierced easily with a fork, which should take approximately 5 to 10 minutes.

The final step is to drain the excess liquid from the tomatoes and blot them with paper towels. The tomatoes can then be topped with oil and stored in an airtight container in the refrigerator for up to 2 weeks.

Rehydrated tomatoes can be used in a variety of dishes, such as soups, sauces, salads, and sandwiches. They add a sweet and concentrated flavour to recipes and are a great way to include the health benefits of tomatoes in your meals all year round.

Creative ways to use dehydrated tomatoes

Dehydrated tomatoes can be used in a variety of creative ways. Here are some ideas to elevate your dishes with dehydrated tomatoes:

Salads and Sandwiches

Enhance your winter salads or sandwiches by rehydrating dehydrated tomatoes. Marinate them in a bit of salad dressing, or puree them into a tomato vinaigrette. You can also add them to scrambled eggs or deviled egg filling.

Snacks and Appetisers

Create your own tomato chips by thinly slicing tomatoes, drizzling them with olive oil, and sprinkling them with salt before dehydrating. These crispy treats can be enjoyed straight out of the jar or served with dips like pesto or aioli. Alternatively, dehydrate tomatoes until they are chewy, resembling fruit leather or candy, for a sweet and savoury snack.

Soups and Sauces

Dehydrated tomatoes are perfect for adding a burst of flavour to your soups and sauces. Simply rehydrate them by simmering in a bit of water or your favourite stock. You can also puree dehydrated tomatoes into a powder, which can be used as a tomato paste alternative or to boost the flavour of lacklustre tomatoes.

Enhancing Dishes

Use dehydrated tomatoes as a versatile garnish to elevate fish, chicken, or vegetable dishes. They can also be crumbled or minced and added to biscuits, cornbread, savory muffins, or waffles for a savoury surprise. For a more intense tomato flavour, add them to pasta sauces or bruschetta.

Creative Combinations

Get creative by making a sundried tomato "pesto." Pulse together dried tomatoes, water, nuts, herbs, and grated Parmesan cheese in a food processor until you reach your desired consistency. This versatile spread can be used on pasta, pizza, sandwiches, or as a sauce for vegetables or eggs.
