30 Minutes in the Oven Equals How Long in the Air Fryer?
The instant answer, plus the food specific breakdown below.
Temperature: set the air fryer 25°F (about 15°C) lower than your oven recipe states. Check food 2 to 3 minutes before the end on your first attempt.
30 Oven Minutes by Food Type
| Food Type | Oven Time | Air Fryer Time |
|---|---|---|
| General / Mixed | 30 min | 24 min |
| Chicken and Poultry | 30 min | 23 min |
| Red Meat | 30 min | 25 min |
| Fish, Seafood or Vegetables | 30 min | 23 min |
| Baked Goods | 30 min | 25 min |
| Frozen Foods | 30 min | 26 min |
| Casseroles and Dense Dishes | 30 min | 26 min |
Frozen foods and dense dishes keep more of the original time because they need the extra minutes to heat through. For temperature and portion adjustments too, use the full oven to air fryer calculator.
What Cooks in 30 Minutes?
Thirty minutes is the single most common cooking time in oven recipes, the default for casseroles, whole chicken pieces, roasted vegetables, small cakes, stuffed peppers and most weeknight bakes. It converts to 24 minutes in the air fryer, and because so many recipes use it, this is the conversion worth memorising: 30 becomes 24.
\nThe variety inside this bracket is wide, so food type matters more than at shorter durations. Bone in chicken wants the full 24 minutes and a thermometer check. Roasted vegetables are often done at 18 to 20. Anything baked, brownies, small cakes, sits closer to 25 or 26 minutes at a lower temperature than the standard drop, which the baking conversion page covers properly.

30 Minutes Oven to Air Fryer: Frequently Asked Questions
About 24 minutes, with the air fryer set 25°F (15°C) lower than the oven temperature. This is the most common recipe time there is, so 30 becomes 24 is the conversion worth memorising.
Not quite. Dense casseroles keep more time, around 25 to 26 minutes, because heat takes longer to reach the centre. Chicken pieces take the standard 24 and should be verified at 165°F internal.
Use gentler settings for cakes: drop the temperature further than the standard rule, keep 25 to 26 of the minutes, and test with a skewer. Fast moving air browns cake tops before centres set, so baking has its own conversion rules.
Smaller portions, a preheated basket, or a high wattage model all speed things up. The 20% cut assumes a medium portion in a typical basket. Treat 24 minutes as the outer edge and start checking at 20.
