How the air fryer converter works
An air fryer is essentially a compact convection oven. Its fan circulates superheated air at high speed around the food, making heat transfer far more efficient than a conventional oven's radiant heat. The result: you can cook at a lower temperature and for less time — typically 25°F (15°C) cooler and 20% faster.
Because air fryers require little or no preheating (2–3 minutes at most versus 10–15 minutes for a conventional oven), total cooking time including preheat is often 25–30% shorter overall. The compact basket also means heat is never far from the food surface, which is why the temperature reduction prevents burning the exterior before the interior cooks through.

Your recipe says 400°F for 25 minutes in a conventional oven. You want to cook it in the air fryer instead.
10 common recipes: oven vs. air fryer
Use this table as a starting point. Actual times vary with the size and thickness of food, how full the basket is, and the specific air fryer model. Always check doneness a few minutes early on your first attempt.
| Recipe | Oven Temp | AF Temp | Oven Time | AF Time |
|---|---|---|---|---|
| Chicken breast | 400°F / 205°C | 375°F / 190°C | 25 min | 20 min |
| Frozen fries | 425°F / 220°C | 400°F / 205°C | 25 min | 20 min |
| Salmon fillet | 400°F / 205°C | 375°F / 190°C | 15 min | 12 min |
| Roasted vegetables | 425°F / 220°C | 400°F / 205°C | 30 min | 24 min |
| Small cake (6 in) | 350°F / 175°C | 325°F / 165°C | 35 min | 28 min |
| Cookies | 375°F / 190°C | 350°F / 175°C | 12 min | 10 min |
| Pork chops (1 in) | 400°F / 205°C | 375°F / 190°C | 20 min | 16 min |
| Shrimp | 400°F / 205°C | 375°F / 190°C | 10 min | 8 min |
| Bacon | 400°F / 205°C | 375°F / 190°C | 12 min | 10 min |
| Fish fillets | 400°F / 205°C | 375°F / 190°C | 15 min | 12 min |

Tips for air fryer cooking
The 25°F / 20% rule is a reliable starting formula, but getting great results also depends on a few habits that seasoned air fryer cooks develop quickly.
- Don't overcrowd the basket — air fryers work by circulating air around every surface of the food. A single layer with space between pieces gives far better results than a packed basket, which essentially steams the food instead of crisping it.
- Check 5 minutes early for frozen foods — frozen items often cook faster than the formula predicts because there is no residual cold oven air to contend with. Start checking 5 minutes before the converted time.
- Use a thermometer for thick cuts — for whole chicken, thick pork roasts, or anything over 2 inches thick, use the 15% time reduction rather than 20%, and always verify internal temperature with an instant-read thermometer.
- Shake or flip halfway — for fries, nuggets, shrimp, or any smaller items, shaking the basket or flipping pieces halfway through ensures even browning on all sides.
- Lightly oil the food, not the basket — a light spray or brush of oil on the food itself promotes browning; oiling the basket can cause smoking. For very lean proteins like fish, a thin coat of oil prevents sticking and aids crisping.
Accuracy and limitations
The −25°F / ×0.80 conversion is an industry-standard rule of thumb derived from manufacturer testing and home cook experience. It applies reliably to most proteins, vegetables, and baked goods in the 325–450°F oven range. However, every air fryer model runs slightly differently — some run hot, some have more powerful fans — so treat converted times as a starting point, not a guarantee.
Very delicate items (soufflés, custards, chiffon cakes) are generally not suitable for air fryer cooking, as the forceful airflow can disrupt structure. Wet batters (tempura, beer batter) drip and create smoke without a specialized air fryer rack. For anything involving liquid-heavy sauces or very large formats (full turkey, large casseroles), a conventional oven remains the better tool.
