1. Not All Foods Cook Well in Air Fryers
Foods that require even, low-temperature cooking over a long time — like large roasts, casseroles, baked goods, and some vegetables — often do better in a conventional oven. Air fryers circulate very hot air in a confined space, which can lead to uneven cooking for dense or thick foods.
2. Texture and Quality Can Be Compromised
While air fryers excel at crunch, they can dry out foods that benefit from moisture retention. A turkey breast or a moist cake, for example, may come out dry or over-browned in an air fryer.3. Potential for Acrylamide Formation
Some research suggests that cooking starchy foods (like potatoes) at high temperatures — especially with direct hot air contact — could increase levels of acrylamide, a compound linked to health concerns when consumed in large amounts. Oven cooking at appropriate temperatures can sometimes reduce this risk, depending on the method used.
