Oven to Air Fryer Conversion Guide: Temperature, Time & Charts

The complete, no-guesswork guide to converting any conventional oven recipe for your air fryer. Covers the golden –25°F / –20% time rule, a full conversion chart across every food type, frozen food rules, brand-specific adjustments for Ninja, Cosori and Philips, safe internal temperatures — plus a free oven to air fryer calculator to do the maths for you.

Why You Need to Convert Oven Recipes for an Air Fryer

An air fryer is not simply a smaller oven. It is a compact convection cooker with a high-speed fan that blasts superheated air around your food at significantly higher velocity than a conventional oven. This makes it cook food 25–30% faster and with more aggressive browning than a standard oven at the same temperature.

If you put a chicken breast in your air fryer at the same temperature and time your oven recipe suggests, you will likely get a result that is over-browned on the outside and potentially dry inside. That's why knowing how to convert oven to air fryer is one of the most useful kitchen skills you can have.

The Golden Conversion Rule: –25°F & –20% Time

After decades of testing and widespread community consensus, one rule consistently works as a reliable starting point for the vast majority of oven recipes:

Quick examples

• Chicken thighs at 400°F for 35 min → Air fryer: 375°F for 28 min
• Roasted vegetables at 425°F for 25 min → Air fryer: 400°F for 20 min
• Baked salmon at 375°F for 20 min → Air fryer: 350°F for 16 min
• Pizza at 220°C for 15 min → Air fryer: 200°C for 12 min
• Jacket potato at 200°C for 60 min → Air fryer: 185°C for 48 min

Frozen Food Air Fryer Conversion Rules

Frozen food behaves differently — the moisture in ice crystals creates steam as it melts. The key insight:

Not all air fryers are created equal. The same recipe can produce noticeably different results depending on which brand you own:

Safe Internal Temperatures — Never Guess on Meat

The only way to confirm meat is cooked safely is with an instant-read thermometer. Use these USDA-recommended temperatures:

Pro Tips for Perfect Air Fryer Results

1. Use a light coat of oil — but not too much

A thin coat of high-smoke-point oil (avocado, sunflower) promotes Maillard browning and crispiness. Too much oil creates steam and makes food greasy.

2. Pat proteins completely dry before cooking

Surface moisture is the enemy of crispiness. Before placing any meat, fish or vegetables in the air fryer, pat them dry with kitchen paper.

3. Season generously — flavour concentrates

The rapid air circulation causes surface moisture evaporation, concentrating flavours on the exterior. Season more assertively than you would for the oven.

4. Cover the top with foil if browning too fast

Because the heating element is directly above, the top of baked goods can brown before the interior is cooked. Lay foil loosely over the top for remaining time.

5. Never use non-stick spray on the basket

Aerosol non-stick sprays contain additives that damage basket coatings over time. Use an oil mister with pure oil, or apply oil directly to food.

6. Cook in batches for best results

The single biggest mistake is overcrowding. Two smaller batches always beats one overfull basket. The second batch cooks slightly faster because the air fryer is already hot.

Frequently Asked Questions

What is the general rule for oven to air fryer conversion?

The golden rule is to reduce the oven temperature by 25°F (about 15°C) and reduce the cooking time by 20%. For example, 400°F for 30 minutes in the oven becomes 375°F for 24 minutes in the air fryer.

Does the conversion rule work for frozen food?

For most frozen foods, keep the temperature the same as the oven package instructions but reduce time by 25–40%. Frozen fries at 425°F for 20 min typically cook in 10–14 min in an air fryer. Do not thaw — cook from frozen.

Do different air fryer brands need different settings?

Yes. Ninja runs hotter — reduce time by an extra 5–10%. Cosori is standard. Philips has gentler airflow and may need 1–2 extra minutes. Always check your model's manual.

Should I preheat my air fryer before cooking?

Yes — preheating for 3–5 minutes ensures the cooking chamber is at target temperature. This gives more consistent results, especially for meats and baked goods. Skip preheating = add 2–3 min to cook time.

Can I bake in an air fryer using oven recipe settings?

Yes, but use a smaller reduction — about 15–20°F instead of 25°F — for delicate baked goods like cakes and muffins. The smaller chamber means heat is more intense and tops brown quickly. Cover with foil if needed.

What is 180°C oven converted to air fryer?

180°C oven converts to approximately 165°C in an air fryer (reduce by 15°C). Cooking time should also be reduced by 20%. So 180°C for 30 min becomes 165°C for 24 min.

Why does my air fryer food come out burnt outside and raw inside?

This usually means the temperature is too high for the thickness of the food. Lower temp by an additional 25°F and extend time slightly. Also avoid sugary sauces or marinades which burn quickly in intense heat.

Can I use a convection oven chart for my fan oven?

If your recipe is for a convection (fan) oven, temps are already lower. Only reduce by 10–15°F (not the full 25°F) and time by 15% (not 20%). Air fryers and fan ovens use similar technology — the main difference is chamber size and fan speed.
