Why Experts Warn Against Replacing an Oven With an Air Fryer
1. Air fryers cook differently than ovens
Air fryers use intense, concentrated convection heat in a very small chamber.
This means food cooks faster, but:
-
It can dry out or burn easily.
-
Recipes designed for oven heat may not translate well.
Many baked goods (cakes, breads, casseroles) require gentle, even heat an air fryer cannot provide.
2. Capacity is much smaller
Air fryers hold only a small amount of food.
Replacing an oven for:
-
family meals
-
large cuts of meat
-
full baking sheets
…is impractical.
Overfilling the air fryer causes uneven cooking and unsafe temperature zones.
3. Some cookware is unsafe in an air fryer
Because air fryers have much closer heating elements, items that are safe in an oven—such as parchment paper, some baking dishes, or even foil—can:
-
burn
-
melt
-
block airflow
This can be a fire hazard.
4. Not all foods are safe to cook in an air fryer
Foods that release a lot of moisture or oil (high-fat meats, cheese-heavy dishes) can cause:
-
smoking
-
splattering
-
potential grease fires
Ovens handle these foods more safely because of better ventilation and pan space.
5. Temperature accuracy varies
Air fryers often run hotter than the displayed temperature.
When baking or cooking precise recipes (custards, roasts, pastries), this can:
-
ruin texture
-
undercook or overcook the food
-
create food safety risks
6. Airflow matters
Air fryers require unobstructed airflow around the basket.
Certain techniques that are normal in ovens—like covering a casserole with foil—can block airflow and cause overheating.
When an Air Fryer Is a Good Substitute
-
Reheating leftovers
-
Small batches of roasted vegetables
-
Frozen snacks
-
Chicken wings, small pork chops, cutlets
-
Toasting small items
-
Quick crisping
When an Oven Is Still Better
-
Baking breads, cakes, pies
-
Large roasts (turkey, big brisket, bone-in ham)
-
Casseroles, lasagnas, pot pies
-
Cooking for multiple people
-
Dishes requiring exact temperature control
