Air fryers are basically high-powered, compact countertop convection ovens. Instead of submerging food in oil like a deep fryer, they use a robust fan and heating element to rapidly circulate super-hot air around the food. This gives you that "fried" crispy exterior with little to no oil.
While air fryers offer a quick and healthy alternative to deep-frying, they come with several notable disadvantages. These include severe size constraints, a high risk of burning certain foods, tedious cleaning, potential health considerations regarding non-stick coatings, and counter space consumption.
Air frying is highly suitable for diabetics as it uses hot circulating air to crisp food, requiring up to 80% less oil than deep-frying. This significantly reduces calories and fat, helping you manage weight and protect heart health.
The air fryer 20/20 rule is a, roughly, 20-25% reduction in both cooking temperature and time when converting standard oven recipes. Specifically, it means reducing the temperature by 20–25°F (or 15−20∘𝐶) and reducing the cooking time by 20% to avoid overcooking and burning food due to rapid air circulation.
Wet-battered foods, large whole roasts, cheese-heavy dishes, leafy greens, and raw grains generally cannot be cooked properly in an air fryer. These items often result in messy, unevenly cooked, or dry food due to the high-speed air circulation and limited space. Wet batters slide off, leafy greens burn or fly around, and cheese melts through the basket.
Avoid these 5 foods in your air fryer:
Yes, you can safely use aluminum foil in an air fryer. Because an air fryer works like a small convection oven, it is safe to use—but you must follow specific placement and safety rules.
Air frying and baking are nutritionally very similar because both use circulating dry heat to cook food. However, air frying is generally considered slightly healthier because its rapid airflow requires significantly less oil to achieve a crispy texture, which reduces total fat and calorie intake.
This is because the air fryer's concentrated heat can cause the outside to brown before the inside is fully cooked. For example, if your oven recipe calls for 400°F, try 375°F or even 350°F in the air fryer for crispy results.
An air fryer only has one heating element on top. A convection oven, which is also an air fryer of sorts, has one on top and one on the bottom. I do find that flipping can make the underside more well done, or crispy. A full basket of fries needs a few flips.
The #1 absolute worst foods for your blood sugar are sugar-sweetened beverages (sodas, sweetened iced teas, fruit punches, and energy drinks).
Air fryers may be better for you than deep fryers, but they're only as healthy as the food you put inside. They won't magically remove the saturated fat from bacon or the trans fats from a bag of processed chicken wings. To reap the benefits, reach for better-for-you options like vegetables and lean proteins.
Clean your air fryer by letting it cool and unplugging the unit. Soak the basket and tray in warm, soapy water and scrub with a non-abrasive sponge. Wipe the interior and exterior with a damp cloth, and gently clean grease off the heating element with a soft brush.
You can prevent stubborn grease from forming
Air fryers accelerate this process because of the high heat and circulating air, creating tough layers that get harder to remove each time you cook. Use protective liners like parchment paper or silicone mats in the basket to catch grease before it hits the surface.
An air fryer is generally healthier than a microwave if your goal is reducing fat and calories, as it uses 70–80% less oil than traditional frying. However, microwaves are better at preserving heat-sensitive vitamins and nutrients since they cook much faster.
The safest air fryers ditch conventional Teflon/PTFE coatings for completely non-toxic alternatives made of ceramic, stainless steel, or heat-tempered glass. Top-rated, thoroughly vetted, PFAS-free options include the COSORI TurboBlaze (ceramic), the Ninja Crispi Pro (glass), and the Fritaire (glass bowl).
You can safely use parchment paper in an air fryer as long as it's oven-safe and kept below 450°F. Trim or perforate the parchment and weigh it down with food to prevent airflow blockage or fire hazards.
Below, you'll find 10 foods that the air fryer can annihilate.
Always preheat your air fryer with the basket inside the unit. Leaving the basket in lets the metal heat up so it will toast or sear your food as soon as you drop it in.
Air-fried potatoes can be a healthy, low-calorie alternative to deep-fried versions, provided you use minimal oil. Because air fryers function like convection ovens, they crisp potatoes with hot air rather than submerging them in vats of fat.
Avocado oil and light olive oil shine for their high smoke points, while ghee and peanut oils each add unique flavours and health perks. For those looking to experiment, grapeseed and refined coconut oils bring subtle tones and nutritional benefits.
The healthiest cooking methods are steaming, poaching, and microwaving. They require no added fats and use low, gentle heat, which prevents the formation of harmful compounds and best preserves the food's natural nutrients, vitamins, and antioxidants.
You can line your air fryer basket with perforated parchment paper liners, silicone air fryer pots, or aluminum foil. Always place food on top of the liner immediately after preheating so the weight holds it down, and never use a liner without food on it to prevent fire hazards.
“Air frying is definitely a healthier alternative to deep-frying,” said registered dietitian and diabetes care and education specialist, Gale Pearson of TPMG Nutrition Services in Newport News and Williamsburg. Air fryers work like convection ovens and mimic the effects of deep-frying with hot air instead of oil.
Yes, you can absolutely air fry taco shells! The air fryer is perfect for quickly warming store-bought hard shells, making crispy homemade shells from soft tortillas, or frying up stuffed tacos.
