Roasting root vegetables

I try my best to eat seasonal produce, but by February it’s a struggle. Like other Chicagoans, I’ve endured a marathon of gray-skied days and yearn for green grass, green leaves, and green vegetables. Asparagus, leeks, and artichokes won’t be harvested in the Midwest for weeks, but I start to fantasize about them anyway, which is a shame, I know. Carrots, sweet potatoes, and other root vegetables offer so much promise this time of year. They can serve as sunken treasures in soup and nuggets of flavor in stir-fries. They can also be transformed into mouthwatering sides using one of the simplest cooking methods of all: roasting.

Thanks to their low moisture content, root vegetables develop a sweet-savory flavor when exposed to high heat. Coating them with a thin layer of oil keeps them from drying out, and cutting them into relatively uniform pieces ensures even cooking. To build in even more flavor, toss root vegetables with your favorite hardy herbs or sprinkle them with a smidge of your favorite spices. Really, there’s little more to roasting root vegetables, so if you could use a little warmth in your house and in your belly, don’t pass them by.

How to Roast Root Vegetables

Heat the oven to 400 degrees. Wash your favorite root vegetables. Here, I’m using parsnips, carrots, and sweet potatoes because I love the color combination and the way their gentle flavors blend together. 

Cut off the stem ends from the carrots and parsnips. Peel the vegetables and cut them down the middle lengthwise to create a flat surface.

Place the parsnip and carrot halves on a cutting board, cut side down. Roughly chop them into one-inch pieces, crosswise. Discard the very narrow ends.

Place the sweet potato halves on the cutting board, cut side down. Cut them into three large pieces, lengthwise. Roughly chop each piece into one-inch pieces, crosswise. 

Line a baking sheet or shallow pan with aluminum foil and layer the chopped vegetables on top. Sprinkle them with salt, pepper, and just enough olive oil to coat. Rub the vegetables with your fingers to thoroughly coat them with the oil. This will prevent them from sticking.

Cook the vegetables, flipping and stirring occasionally, for 35 minutes, or until they are tender enough to pierce with a fork.

For dinner tonight, I roasted delicata squash, carrots, apples, and a handful of golden raisins. I drizzled a little canola oil and honey over the top, mixed it with my hands, and put it in the oven for about 20 minutes at 425 degrees (the pieces were small). It was delicious! A wonderful combination of sweet tastes from the honey, raisins, and the natural sweetness of the veggies and apples.

Yum! However, I would use parchment paper, instead of aluminum foil, because of the toxicity transfered from the aluminum to the food. Also, olive oil becomes toxic when subjected to high heat, as it is in this case. I prefer to use coconut oil, instead. http://www.drpepi.com/aluminum-poisoning.php http://www.examiner.com/article/cooking-with-olive-oil-at-high-heat-can-be-toxic

Love roasted vegetables and I use purple potatoes to add color as well. I have a tip for you, instead of drizzling olive oil then fingering the vegetables to coat them, I put all of my cut veggies in a ziplock bag, drizzle in the oil and seasonings, then close it and give the bag some good turns and shakes. It evenly coats all the veggies and clean up is a lot easier. :) Fresh springs of rosemary are wonderful when they are added the last 10 minutes of roasting, but I always use Herbes de Provence when I roast my veggies. Brings me back to France.

I have some in the oven now. I always use coconut oil at high temps also. I WISH I read to use parchment before I got them in the oven. You learn something new every day. :)
