What Is Romanesco?

This funky looking vegetable is also called Romanesco broccoli or Roman cauliflower, but it's neither broccoli nor cauliflower. Some also call it broccoflower, but that name refers to green-colored cauliflower, which it is not. (It's not broccolini or caulilini either.) Rather, romanesco is part of the brassica family along with cauliflower, cabbage, and kale. As such, it's more closely related to cauliflower than broccoli. (Did you know there are a bunch of different types of kale?)

Romanesco dates back to 16th century Italy but didn't debut in the U.S. until the 1990s. It has a texture similar to cauliflower but is slightly crunchier with a bit of a nutty flavor. It's covered in cone-shaped florets that make it look sort of like a miniature Christmas tree. (Cute, right?)

It's available during the late fall and winter and you'll find it sold as a head (similar to cauliflower), which can be up to 5 pounds each (!!). You can probably find it at your local farmer's markets or in select supermarkets when it's in season.

Romanesco Nutrition Facts

One-half cup chopped romanesco provides 10 calories, 2 grams carbs, 1 gram fiber, 1 gram protein, and is fat-free. It also provides numerous vitamins and minerals including a whopping 90 percent of the daily recommended amount of vitamin K (important for bone and heart health) and 60 percent of the daily recommended amount of the antioxidant vitamin C. It's also a good source of folate and vitamin A, providing 10 percent of the daily recommended amount of each. (Nutritionally, it's pretty similar to broccoli: One-half cup of chopped broccoli provides 15 calories, 3 grams carbs, 1 gram fiber, 1 gram protein, and is fat-free.)

Buying and Storing Romanesco

When selecting Romanesco, look for heads that are bright in color and have their leaves still attached. The stems should be firm and show no signs of wilting. When you pick up a head, it should be heavy for its size. Once you bring it home, store your fresh Romanesco unwashed in a resealable plastic bag in the fridge for up to 1 week.

How to Cook Romanesco

You can prepare romanesco similar to cauliflower or broccoli—raw or cooked—but remember that it still has its own unique flavor.

  • Blanch romanesco florets for several minutes in boiling water then shock on ice so they don't get mushy. Add larger chunks to crudité, soups, or grain bowls, or chop and add to pasta, rice dishes, or omelets.
  • Steam the florets and remove immediately from the heat so they maintain their crispiness. Sprinkle with salt and pepper and a touch of extra-virgin olive oil and sprinkle of Parmesan cheese.
  • Add it to a tofu, chicken, or beef stir-fry with other vegetables like carrots, snow peas, and mushrooms.
  • Roast them (like in the recipe below).
