Ninja Foodi Tomato Confit: A Culinary Delight
Creating tomato confit in your Ninja Foodi is remarkably simple and yields an incredibly flavorful result. This method requires no special racks, making it an excellent starting point for beginners. Tomato confit is essentially slow-cooked tomatoes in olive oil, often infused with garlic and herbs, resulting in tender, bursting tomatoes that are sweet, savory, and intensely aromatic.
To begin, simply layer the bottom of your Ninja Foodi pot with a generous amount of whole cherry tomatoes. Drizzle them with about 1/2 cup of quality olive oil. Thinly slice two cloves of fresh garlic and scatter them over the tomatoes, followed by a sprinkle of sea salt, a teaspoon of balsamic vinegar, and a few sprigs of fresh or dried thyme. Gently mix all the ingredients to ensure the tomatoes are evenly coated.
Select the “Bake” mode on your Ninja Foodi and set the temperature to approximately 120°C (250°F) for about 45 minutes. The goal is to cook the tomatoes until they are soft, tender, and slightly squishy, with their skins just beginning to wrinkle. Stir every 10-15 minutes to prevent sticking and ensure even cooking. This gentle baking process allows the flavors to meld beautifully, creating a rich and concentrated tomato essence.
Once your tomato confit is ready, you can enjoy it immediately or store it for later. Ideally, this confit serves as a perfect base for a homemade pressure cooker spaghetti sauce, which you can even prepare in the same pot! If you’re not using it right away, allow the confit to cool completely before transferring it to airtight containers. Properly stored in the refrigerator, it will last for up to 3 months, and can be frozen for even longer periods, ensuring you always have a burst of summer flavor on hand.

Dehydrating Tomatoes in Your Ninja Foodi
Dehydrating tomatoes is an excellent way to preserve their flavor and create versatile ingredients for various dishes. Your Ninja Foodi, with its dedicated “Dehydrate” function or even its air crisp mode, makes this process incredibly straightforward. This method concentrates the natural sugars and umami in the tomatoes, resulting in intensely flavorful, chewy bites perfect for snacks, salads, or adding depth to cooked meals.
For best results, slice baby plum tomatoes in half lengthwise, or use thicker slices of larger tomatoes. In a bowl, toss the tomato pieces with a light coating of olive oil. Season generously with a blend of garlic powder, onion powder, dried oregano, dried basil, salt, and black pepper. The olive oil helps distribute the seasonings and aids in the dehydration process, while the herbs infuse a classic Italian flavor profile.
Arrange the seasoned tomato halves in a single layer on your Ninja Foodi’s dehydrator racks, ensuring the skin side is facing down. This allows for optimal airflow and efficient drying. Set your Ninja Foodi to the “Dehydrate” mode at 60°C (140°F) for an initial 3 hours. After this period, carefully flip the tomato pieces and continue dehydrating for another 3 hours. The total dehydration time can vary slightly depending on the thickness of your tomato slices and the moisture content, so always monitor their progress.
Once the dehydration process is complete, the tomatoes should feel firm and leathery, resembling a texture similar to Ninja Foodi beef jerky. To ensure they are fully dried and to prevent condensation, lay the dehydrated tomatoes on paper towels for about an hour after removing them from the Foodi. This allows any residual moisture to escape. Once completely cool and dry, store them in a sealed, airtight container. These dehydrated tomatoes can be enjoyed as a healthy snack, added to trail mixes, or rehydrated in warm water for use in sauces and stews.
Crafting Sun-Dried Tomatoes with Ninja Foodi Air Fry
While often used interchangeably, there’s a subtle distinction between purely “dehydrated” and “sun-dried” tomatoes, particularly in texture and preparation. Traditional sun-dried tomatoes are intensely flavored, often chewy, and can be achieved efficiently using your Ninja Foodi’s air fryer function. The “Air Crisp” mode provides the perfect environment for achieving that concentrated, slightly shriveled texture reminiscent of true sun-dried tomatoes, but in a fraction of the time. The key difference lies in the level of dryness; sun-dried tomatoes often retain a bit more pliability compared to fully brittle dehydrated ones.
The cooking time for your sun-dried tomatoes will depend largely on your desired final texture and how you plan to use them. If you’re incorporating them into a homemade sauce, you might prefer them with a bit more texture, still soft and pliable, to blend seamlessly. For pizza toppings, baked goods, or antipasto platters, you might aim for a more thoroughly dried, firmer consistency. The beauty of using your Ninja Foodi is the ability to check them frequently and adjust the cooking time to meet your specific needs.
Storing Sun-Dried Tomatoes Long Term
For long-term storage, especially if you plan to enjoy your homemade sun-dried tomatoes in the months to come, it’s crucial that they are completely dry, with absolutely no trace of moisture. They should ideally reach a tough, leathery, almost beef jerky-like consistency. Remember that as they cool, they will continue to dry out and harden further, so account for this during the cooking process.
Once cooled, transfer the sun-dried tomatoes to a thick freezer bag. The most important step for long-term storage is to remove as much air as possible from the bag; a vacuum sealer works best, but you can also use the water displacement method with a zip-top bag. Store the sealed bag in a cool, dark place, ideally no warmer than 60°F (15°C), away from direct sunlight. Stored this way, your sun-dried tomatoes can last for 6-9 months, ready to enhance salads, pastas, sandwiches, and more throughout the year.

Ninja Foodi Tomatoes and Onions: Perfect for Salsa and Beyond
The Ninja Foodi’s “Air Crisp” function is incredibly versatile, allowing you to roast a variety of vegetables alongside your tomatoes. As demonstrated in our guide on How to Roast Tomatoes in Air Fryer, incorporating other ingredients like onions and jalapeños can create a fantastic base for blended sauces or salsas. Roasting whole tomatoes, jalapeños, and onions together in the air fryer basket infuses them with a beautiful smoky depth that is perfect for a vibrant homemade salsa. Simply toss them with a touch of olive oil and seasonings, then air crisp until tender and slightly charred before blending.
Alternatively, if you prefer the “Bake” function, you can dice yellow onions and cook them alongside your tomatoes and olive oil. The timing will remain similar to our tomato confit method, as the onions will soften and caramelize beautifully in the gentle heat, adding another layer of sweetness and complexity to your dish. This combination is excellent for side dishes, bruschetta toppings, or mixing into grain bowls.

How Long to Cook Tomatoes in Ninja Foodi: Understanding Various Methods
The cooking time for tomatoes in your Ninja Foodi can vary significantly, ranging anywhere from 45 minutes to 6 hours. This wide range depends on several factors: the specific cooking mode you’re using (bake, dehydrate, or air crisp), the size and type of tomatoes, and most importantly, your desired level of “doneness.”
- Bake Mode (Confit): For a soft, squishy confit, expect around 45-60 minutes at 120°C (250°F). You’re looking for tomatoes that have burst their skins and are tender enough to mash easily.
- Air Crisp Mode (Sun-Dried Style): To achieve a chewy, sun-dried texture, cooking times generally fall between 1 to 2 hours at a moderate temperature like 120°C (250°F) or slightly higher if aiming for more char.
- Dehydrate Mode (Fully Dehydrated): For thoroughly dried, leathery tomatoes, plan for a longer duration, typically 4-6 hours at 60°C (140°F).
The best aspect of using the Ninja Foodi is its accessibility; you can open the lid and check on your tomatoes frequently. This allows you to remove them precisely when they reach your preferred texture and consistency, ensuring perfect results every time. Don’t be afraid to pull them out a little earlier or let them go a bit longer based on visual cues and how they feel.
How Long to Roast Tomatoes in Air Fryer for Soup
If your ultimate goal is to create a rich and flavorful sun-dried tomato soup, roasting the tomatoes in the air fryer first will significantly deepen their flavor profile. This process concentrates their natural sweetness and umami, resulting in a bold, rich soup that stands apart from simply cooking down fresh tomatoes. For soup purposes, I recommend following the 45-minute confit steps described earlier, utilizing olive oil and seasonings. The objective here is to soften and season the tomatoes thoroughly, making them ready to be pureed into a silky-smooth, intensely flavored soup or a delightful side dish.
Can You Can Tomatoes in Ninja Foodi? Safety and Equipment
It’s important to clarify that electric pressure cookers, including the Ninja Foodi, are not designed or recommended for safe home canning. While these appliances can reach high temperatures and pressure, they often lack the precise pressure control and sustained high temperatures required for safe pressure canning of low-acid foods like tomatoes. The internal temperature and pressure necessary to kill harmful bacteria (like Clostridium botulinum) are specific and must be maintained consistently for a certain duration, which standard multi-cookers cannot guarantee.
Additionally, electric pressure cookers typically have a smaller capacity, making them unsuitable for accommodating standard canning jars in the quantities needed for efficient canning. For safe home canning, you must use a dedicated stovetop pressure canner, which is specifically engineered to reach and maintain the necessary temperatures and pressures with precision. For those interested in preserving, we have guides like how to can jam using appropriate methods.
