Conclusion
Air fryers are excellent machines: fast, convenient, lower‑oil, great for certain foods, small batches, crisping. But experts caution against treating them as full replacements for ovens. When cooking large meals, baking, roasting, or for volume, ovens often win on capacity, quality, cost efficiency.
If you want to “use your air fryer smartly, not just constantly” — do this:
Evaluate what you’re cooking, how much, how often.
Do the wattage / cost calculation.
Maintain your appliances well.
Also, keep an oven around unless you invariably cook only small portions.
In short, the expert advice is: Don’t ditch your oven just because air fryers are trendy. Instead, view the air fryer as a useful supplement to your kitchen, not a complete replacement
