What You'll Learn

Choosing your vegetables
You can also use frozen vegetables, like a bag of frozen cauliflower, broccoli, or carrots, and roast them in the air fryer without any additional preparation.
Root vegetables, like beets and sweet potatoes, can be roasted in an air fryer, but they take longer to cook, so they may not be the best choice if you're looking for a quick option. However, if you're willing to parboil them first, they can be a great option for air fryer roasting.
When choosing your vegetables, consider the flavors you want to create. For example, if you want a more earthy flavor, root vegetables are a good choice. If you're looking for a crunchier texture, roasting vegetables like broccoli or kale can deliver that.

Preparing your vegetables
Firstly, select the vegetables you want to roast. You can choose from a variety of options, such as bell peppers, zucchini, squash, broccoli, cauliflower, Brussels sprouts, potatoes, carrots, asparagus, green beans, or any other vegetable you prefer. It is recommended to avoid tough root vegetables like beets, as they require a longer cooking time.
Once you have chosen your vegetables, wash and rinse them thoroughly. Then, cut the vegetables into uniform sizes, typically around 1-inch pieces. This ensures even cooking and browning. Place the chopped vegetables in a large bowl.
Next, add a drizzle of oil to the bowl. You can use extra virgin olive oil, avocado oil, or coconut oil. The oil helps the vegetables brown and soften during cooking. Give the vegetables a good toss to ensure they are evenly coated with oil. You can also add spices and herbs to the bowl and toss again to coat the vegetables with the seasonings. Some popular seasoning options include Italian seasoning, garlic powder, salt, and pepper.
If you are using potatoes, a helpful tip is to par-cook them in the microwave before adding them to the air fryer. Cut the potatoes into small chunks, place them in a microwave-safe dish with water, and cook for about 3 minutes. Drain the water, and then add your desired spices, salt, and a bit of cooking spray before placing them in the air fryer.
After your vegetables are prepared and seasoned, preheat your air fryer to a temperature between 360-400 degrees Fahrenheit. While the air fryer is warming up, spray the basket insert with a non-stick cooking spray to prevent sticking.
Now, you are ready to place the vegetables into the air fryer basket. Arrange them in a single layer to ensure even cooking. Avoid overcrowding the basket, as this can affect the cooking time and quality. Depending on the size of your air fryer and the amount of vegetables, you may need to cook in batches.

Seasoning and coating
When it comes to seasoning and coating your vegetables for air frying, there are several options to consider. Firstly, decide on the type of oil you want to use. Extra virgin olive oil is a popular choice for its flavour and high smoke point, but alternatives such as avocado or coconut oil can also be used. Oils help the vegetables to brown and soften, and they can be drizzled or sprayed onto the vegetables before cooking.
After choosing your oil, select your seasonings. A simple combination of salt and pepper is always a good option, but you can also experiment with Italian seasoning, garlic powder, red pepper flakes, cayenne pepper, or crushed ghost pepper salt for an extra kick. If you're feeling creative, try adding some toasted nuts like almonds or cashews for crunch, or squeeze some lemon juice over your vegetables for a tangy finish.
For a more complex flavour profile, consider adding spices like rosemary, garlic, or red wine vinegar to the air fryer and tossing them with the vegetables. If you're cooking in batches, separate the soft vegetables from the hard ones to get the cooking times right, then toss them together at the end.
Finally, don't be afraid to experiment with different vegetables. Bell peppers, zucchini, squash, and onions are great options, but you can also try broccoli, cauliflower, carrots, Brussels sprouts, or potatoes. Just remember that root vegetables like beets and sweet potatoes may require a longer cook time.

Cooking times and temperatures
The cooking time and temperature for roasted vegetables in an air fryer depend on the type of vegetables and the desired level of crispiness.
Firstly, it is important to note that different air fryers may yield different results. Therefore, it is recommended to keep a close eye on the vegetables while they are cooking to prevent overcooking or burning.
For soft vegetables or those with high water content, such as zucchini, a shorter cooking time is required. These vegetables should be added later in the cooking process if they are being cooked alongside hardier vegetables. A cooking time of 8 to 15 minutes is generally recommended for softer vegetables, with tossing or shaking the air fryer basket halfway through to ensure even cooking and prevent sticking.
Hardier root vegetables, such as potatoes, carrots, and sweet potatoes, require a longer cooking time to become tender. It is advisable to par-cook root vegetables in the microwave before transferring them to the air fryer to speed up the cooking process. When cooking only root vegetables, preheating the air fryer to 360-400 degrees Fahrenheit (180-204 degrees Celsius) and roasting for 10 to 20 minutes is suggested.
Additionally, the desired level of crispiness will impact the cooking time. For a more well-done result, increase the cooking time by a few minutes. Conversely, for a slightly charred but tender texture, aim for the lower end of the cooking time range.
