FAQs
Can I use frozen cauliflower?
Yes. Thaw and pat dry before roasting to avoid sogginess.
Do I need to peel garlic?
No need—roast unpeeled cloves for mellow, sweet flavor.
Why is my cauliflower soggy?
Crowding the pan traps steam. Roast in a single layer for crisp edges.
Can I roast at a lower temperature?
Yes, but cooking time will increase and caramelization may be reduced.
How do I store leftovers?
Cool completely, then refrigerate in an airtight container.
Can I make this vegan?
Omit Parmesan or use a vegan cheese alternative.
Is there a make-ahead option?
Roast fully and reheat before serving; add fresh cheese after reheating.
