Frequently Asked Questions
How long do I roast cauliflower at 400°F?

How long does cauliflower take in the air fryer?

Cauliflower florets take 10–15 minutes at 400°F in the air fryer, shaking the basket once at halfway. Toss with oil first for the crispiest edges.
How long does a whole head of cauliflower take to roast?
+
A whole cauliflower head takes 50–70 minutes at 400°F. Rub the entire head with oil and seasonings and roast until a knife slides through the core with no resistance.

No. Raw cauliflower florets roast beautifully straight from the head — boiling first adds water and makes it harder to get crispy edges. Only blanch first if you're making cauliflower 'steaks' that need a faster finish.
