Recipe FAQ

Can I make this without oil?

Yes, you can roasted frozen cauliflower without oil, but it will be harder to get the spices to stick and the cauliflower may stick to the air fryer basket. I recommend using cooking oil spray to coat the florets and also lightly spray the air fryer basket.

Should I thaw frozen cauliflower before cooking?

There’s no need to defrost frozen cauliflower before cooking. In fact, it’s best to cooking it straight from frozen. They can be added straight into dishes being cooked, like casseroles, stews and oven bakes, or throw in for the last few minutes with pasta being cooked in boiling water.

How long does frozen cauliflower take to cook?

Frozen cauliflower generally takes about 25 minutes to cook in the air fryer. However this depends on your specific air fryer model, the size of the cauliflower florets and how much you are cooking at the same time.
