Overcrowding the basket can block the airflow, leading to uneven cooking and, consequently, dry spots. If you're using a large air fryer, take advantage of the extra space by spreading out your ingredients for even better air circulation.
Most air fryers will need 1-2 teaspoons of oil when cooking; breads will need 1–2 tablespoons to reach the ideal crispiness. Adding the correct amount of oil keep the texture of your food from becoming dry and leathery.
An air fryer's fast-moving convection heat can cause meat and certain vegetables to dry out. Leafy greens, lean meats and certain seafoods, for instance, are no longer welcome in my air fryer.
Try soaking them in water for 30 mins, drain then dry in a tea towel. Take the trivet out of the bottom of your air frier and put in half a tbsp of oil, heat that for 3 mins then put in your chips and move them around in the oil with a plastic spoon so they are lightly coated.
Why is my food not crispy in an air fryer? If your food is not crispy when coming out of an air fryer, you may not have patted it dry before putting it in to cook. Meat or proteins, or foods you may have washed, will fry better without the added moisture.
Another technique is to add a small amount of water to the bottom of the air fryer basket (under the cooking grate, not in direct contact with the food). The steam created from the water can help maintain a humid environment inside the fryer, reducing the chance of food drying out.
Firstly, if your potatoes are still wet before being placed into an air fryer, this can cause your potatoes not to crispen up. You can avoid this by thoroughly patting dry your potatoes before you place them in the air fryer. Secondly, you might be putting in too many potato chips so they aren't cooking evenly.
Chicken breasts should be cooked to 160°F, but if you cook them all the way to that temperature in the air fryer, carryover cooking will take them beyond that temp and cause them to dry out. Stop the cooking five degrees sooner and let carryover cooking do the rest.
I wouldn't bother doing potatoes from the raw state, without soaking. It will take about a half an hour and the texture won't be nearly as rewarding. They just don't get very crispy without that cold soak.
Adding a small amount of water to the bottom of the air fryer can create steam, which keeps the inside of the food tender while allowing the outside to crisp up. For baked goods, such as pastries or bread, a little water can mimic the humid environment of a traditional oven, giving a softer texture or a better rise.
Dehydrate option is to remove moisture content from veggies or fruits to dry and preserve them. Set the function knob to Dehydrate. The preset temperature of 150°F will be shown. If desired, rotate the temperature or timer knob to adjust.
Air fryers cook hot and fast, so the internal temperature can rise 10-15°F after cooking. Aim for your target temperature accordingly. Let the Beef Rest: After cooking, rest the beef for at least 10 minutes. This allows the muscle fibers to relax and redistributes the juices, keeping the roast tender and moist.
Using oil
 Using oil in an air fryer is perfectly fine and helps the meat to remain moist and come out looking golden brown. However, a little oil in an air fryer does go a long way. With most cuts of pork, simply rubbing some oil into the meat will be all you need. You can use either regular olive oil or a spray oil.
While air fryers are popular, the most expensive models can start to get a little pricey, which could undermine their status as a budget item. Taking to social media to share their opinions, many people have revealed that they reckon halogen ovens are the best option for frugal cooking.
Ensure there is enough space between the chicken breasts in the air fryer basket. The air fryer cooks the protein by circulating the hot air, so it is important. Flip the chicken halfway through so both sides cook equally and yield a juicy chicken breast.
After your chicken breasts are done cooking, let them rest for at least half the time that you cooked them for before slicing into them. This will ensure that the breasts stay super juicy and flavorful, and that they're fully cooked.
Entire chickens (with one exception)
 As a result, you'll likely end up with a chicken that's dry, has burnt bits and is unevenly cooked. There is a solution, though. There are air fryer models that come with a rotisserie function. This will give you more than enough room to roast a delicious, juicy chicken.
The drier your food is when it goes in, the crispier it'll be when it comes out. Extra liquid can also cause splattering and smoking, so even if you think your ingredients are dry, give them one last pat with a paper towel before adding them to the basket.
Oil or fat has not been used correctly
 Also, use low-fat snack varieties where possible. It will be difficult to get a crispy result with snacks that have a high-fat percentage. To find out how to use oil in your airfryer correctly, please follow the next tips: Dry the outside of the food properly before you add oil.
Use a spritz of oil
 A very light spritz of oil will ensure your air fryer fries don't dry out. Some people swear by spraying a little of your go-to cooking oil, like canola, olive or avocado, into the basket and over frozen french fries before air frying.
Foil is safe to use in an air fryer so long as you follow three basic rules: never let foil touch the heating element; make sure the foil is weighted so it doesn't blow around the basket; and avoid contact with acidic ingredients, which can cause the foil to leach onto your food.
Air fryers are capable of dehydrating food as they function quite similarly to dehydrators. But you must check your own individual air fryer to see what settings you need to use to dehydrate your own food. Your air fryer needs to be on a low heat to be able to dehydrate food, and it must be at a temperature below 45℃.
