FAQ

Can I use frozen cauliflower instead of fresh?

Yes, just make sure to thaw completely and pat dry with paper towels to remove excess moisture before roasting.

What if I don't have Parmesan-Romano cheese?

Regular Parmesan works perfectly, or try Pecorino Romano for a sharper flavor. Nutritional yeast makes a good dairy-free substitute.

How long will leftovers keep in the refrigerator?

Store covered in the refrigerator for up to 4 days. Reheat in a 400°F oven for 5-7 minutes to restore crispiness.
