Frequently Asked Questions
How long do I roast cauliflower at 400°F?
+
Cauliflower florets take 25–32 minutes at 400°F in the oven, flipping once at halfway. Toss with olive oil and salt, spread in a single layer, and roast until edges are deeply browned.
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.
Should I boil cauliflower before roasting?
+
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.
