Demystifying Root Vegetables + A Get-Started Recipe

Q: I want to eat a healthy diet/lose some weight/keep those pounds off. I know I have to eat lots of vegetables. But how do I get beyond raw carrots, steamed broccoli and salad, salad, and more salad? 

A: Have a wide variety of vegetable dishes at your fingertips.

Unfortunately, this is easier said than done. I don’t know about you, but I didn’t grow up learning how to be innovative with vegetables. In fact, they were generally just a humble afterthought, plopped down next to the good stuff—meat and potatoes—and followed by the highlight of our family dinner—dessert.

Consequently, I’ve spent a lot of time trying to find ways to eat large quantities of vegetables without getting bored. As part of this investigation, I learned to roast vegetables: a sure-fire way to have a lot of ready-to-eat vegetables in the refrigerator.

Roasted Vegetables with Grated Cheese

My initial dishes contained a mix of traditional vegetables: carrots, cauliflower, zucchini, leeks, butternut squash, and so on, with a sprinkling of an herb or spice.

For example, in the photo to the left, the dish contains broccoli, rutabaga, parsnip, and thyme, topped with melted, grated sheep romano. Yum. (Really. The cheese does amazing things for rutabaga.)

Now I’ve started to focus on the humblest of the humble—root vegetables. Apparently, I’m not alone. According to Mark Bittman, a New York Times food columnist and cookbook author, root vegetables are the latest food trend:

“There was a time when the only root vegetables anyone paid attention to were carrots and potatoes…Turnips were déclassé, celeriac unheard of, beets a pain to clean. The perception has changed, in part because it was all wrong; in part because if you’re going to eat seasonal and local, you are going to eat roots in winter, even if you live in California; and in part because roasted root vegetables, which most of us have discovered only recently, are, like, the greatest thing ever.” (New York Times: January 26, 2012)

Q: Why are roasted root vegetables so terrific?

A: Because they taste great, they’re great for you, and they make a great contribution to vegetable variety. (Most of them are also the cheapest vegetable you can buy in the winter.)

Again, starting to use root vegetables is easier said than done because many of them are strange to us. For example, if you’re like I was three months ago, you…

  • Have no idea what to do with a kohlrabi.
  • Think that celeriac (celery root) looks like something from a horror flick.
  • Are convinced that the taste will be strong and possibly bitter.

Here’s the surprise. The interiors of root vegetables are surprisingly mild in taste, non-threatening in appearance, and easy to cook. Just peel ’em (if necessary), chop ’em and throw ’em into a pan.  (You can also eat many raw, but that’s the subject of another post.)



Celeriac/Celery Root

And don’t worry about mixing and matching root vegetables in one dish. Bittman says that when it comes to cooking root vegetables, they are “interchangeable…Their density is quite similar, so they cook at about the same rate. Most contain starchy sugars, so they brown beautifully and become sweet after cooking.”

Recipe: Roasted Root Vegetables with Mustard Dressing

  1. Ready for Roasting

    Spray a large baking pan with cooking spray.

  2. Peel, chop, and add to the pan: 2 kohlrabis, 1 fennel, and 1 celeriac (celery root).
  3. Peel, chop, and add to the pan: 1 onion (for more taste and crunch), 2 cups cabbage (had some leftover from another recipe), 2 parsnips (bought marked-down and needed to be used), and 2 carrots (for colour.) In other words, be creative!
  4. Mix everything together.
  5. Chop up and sprinkle the feathery and tender stem parts of the fennel over the vegetables (to add to the “look” of the dish. A cook is an artist too, right?).
  6. Mix into the vegetables: a dressing* made of of ¼ cup olive oil, 1 tbsp. mustard seed, 1 tbsp. dijon mustard, and ¼ tsp. balsamic vinegar.
  7. Salt, to taste, if you wish. (I usually don’t addd salt to a dish, but let people add their own preferred quantity later.)
  8. Put the pan, uncovered, into a 425° F oven and cook it for 45 minutes.

  1. Fennel is delicious, but *technically* a stem. (Teaching third graders about plant parts = very specific knowledge!) Salsify is the one root vegetable that I’ve never tried, but would like to.

    Another unusual one is gobo, or the root of the annoying weed burdock. They use it quite a lot in Japan, typically in semi-sweet cold cooked salads and stir-fries. Unfortunately, the roots get wicked fibrous if the plant is too old, so you can’t really go pull up the roots and just eat them from the yard.

    • Hi, thanks for letting me know about fennel. Actually, I like very specific knowledge, probably a trait I acquired in 3rd grade. 🙂 I know I have only scratched the surface of the root-vegetable possibilities. I’m looking forward to a lot of experimenting!

  2. Ola! Foodrefashionista,
    Thanks for the info, Here is a great healthy recipe that not many people have tried – Fried Yucca!

    Yucca contains a high amount of vitamin C and carbohydrates. It is also a good source of dietary fiber and contains approximately 120 calories per 1 cup serving.

    1 pound fresh yucca (cassava), cut into 3-inch sections and peeled

    In a pot combine the yucca with enough cold water to cover it by 1 inch. Boil then slowly simmer the yucca for 20 to 30 minutes, or until it is tender.
    Preheat oven to 350? F.
    Transfer the yucca with a slotted spoon to a cutting board, let it cool, and cut it lengthwise into 3/4-inch-wide wedges, discarding the thin woody core.
    Spray cookie sheet with the nonstick cooking oil spray. Spread yucca wedges on cookie sheet. Cover with foil and bake for 8 minutes. Uncover and return to oven to bake for 7 minutes.

    Season with butter and salt alone is fine.

    Keep up the good work
