Before it goes in the basket
Break it into florets by hand where you can rather than cutting through the head — hand-broken florets have rougher surfaces and more edges, and edges are what brown. Toss with oil in a bowl; cauliflower is even more absorbent than broccoli.
Step by step
- 1. Preheat the air fryer to 390°F (200°C) for 2–3 minutes.
- 2. Single layer. Arrange without crowding — air needs to reach every side.
- 3. Cook 12–15 minutes. Shake the basket or flip at the halfway mark.
- 4. Check doneness. Edges are deeply browned and a fork slides into the stems with ease.
The tip that matters
Toss with a pinch of curry powder or smoked paprika; cauliflower is a spice sponge.
Why this temperature
390°F is what turns cauliflower nutty instead of merely soft. Below about 375°F it cooks through without browning, and unbrowned cauliflower tastes of very little.
What usually goes wrong
- Soft but bland. Not hot enough or not long enough. The flavour is in the browning, not the cooking.
- Burnt edges, raw stems. Florets too large. Cut them so no piece is thicker than about 3 cm.
- Wet and pale. Washed and not dried. Cauliflower holds water in its crevices — let it drain properly.
Times vary — here's why
Air fryers differ in wattage and basket size, so treat 12–15 minutes as a range, not a promise: check early the first time, then note what your machine needed. Quantity matters too — a full basket can add 2–3 minutes, and anything stacked will steam instead of crisp. Converting your own oven recipe instead? Use our air fryer conversion calculator.
