How to cook a whole cauliflower in air fryer
Here are the step-by-step instructions for making a roasted head of cauliflower in air fryer. The cooking time can change slightly depending on the size of the cauliflower and the air fryer model.
1. Wash and preheat
Wash the cauliflower and pat it dry. Preheat the air fryer at 160°C / 320°F for 5 minutes.
2. Brush with oil and salt
Brush the cauliflower with oil mixed with salt. Try to cover the top, sides, and any visible gaps between the florets.
3. Place in the air fryer
Place the whole cauliflower in the air fryer basket or tray, stem side down. Leave some space around it so the hot air can move properly.
4. Air fry the first round
Cook at 160°C / 320°F for 10 minutes. Brush or spray with a little more oil, then cook for another 10 minutes. This helps the cauliflower start softening before the spices are added.
5. Make the spice oil
In a small bowl, mix oil with the seasoning or spices from the recipe card. Adding the spice mix after the first round of cooking helps reduce the chance of the spices burning.
6. Brush with spice mix
Brush the spice oil all over the top and sides of the cauliflower. Use the brush to gently push some seasoning into the gaps between the florets.
7. Air fry until golden
Continue to cook at 160°C / 320°F for 10 minutes. Brush or spray with a little oil again, then cook for another 10 minutes.
8. Check for doneness
Depending on the size of the cauliflower, cook for 5-10 minutes more, or until a knife or fork goes through the centre easily. Add lemon juice before serving.
Serve warm with hummus, tahini sauce, buffalo sauce, or your favourite dip.
