What Is Romanesco and How the Heck Do You Cook It?

What Is Romanesco and How the Heck Do You Cook It? This funky looking vegetable is part of the brassica family along with cauliflower, cabbage, and kale. It's available during late fall and winter and you'll find it sold as a head. It has a texture similar to cauliflower but is slightly crunchier with a nutty flavor. One-half cup chopped Romanesco provides a whopping 90% of the daily recommended amount of vitamin K. It's also a good source of vitamin C, folate, and vitamin A. When selecting Romanesco, look for heads that are bright in color and have their leaves still attached. You can prepare Romanesco similar to cauliflower or broccoli—raw or cooked.
