Roasted Root Vegetables with Tahini Pesto

Roasted Rood Vegetables

Growing up in France, I remember hearing countless stories about World War II. Some of them were about food shortages during these hard times, and how when things were really bad, people survived on boiled turnips and rutabaga! Maybe that’s why I don’t remember ever eating them during my childhood! It was only a few years ago that I explored the world of less common root vegetables like parsnips, turnips, rutabaga, taro, and a few others.  It is my opinion that these humble vegetables do deserve a second look and a place on our table! You can mash them, pickle them, roast them, steam them!

Turnip root and greensAbout Turnips

If you wonder what they look like, imagine a large radish. White inside and on the bottom with purple on top.  The root and the leaves (also called turnip greens) are edible. They can be made into fries, coleslaw, stir-fry, or shredded in salads.

Health Benefits of Turnips

Part root and cruciferous vegetable, turnips are good for the immune system because they supply vitamin C, B6, folate, calcium, potassium, copper, and manganese. Not bad for a large-looking radish!
Fun fact: it was a favorite weapon during Roman times to throw at unpopular public figures!

Close up raw parsnipAbout Parsnips

Parsnips are a cross between carrots and parsley. I often wonder how this came about! They become sweeter when roasted just like carrots do.
Fun fact: parsnips were used as a source of sugar in Europe before cane and beet sugars were available.

Are parsnips good for you?
Yes, they are high fiber, in potassium, vitamin C and B6/Folate. They also have anti-inflammatory and anti-fungal properties.

RutabagaAbout Rutabaga

It is a member of the mustard family and a cousin of the turnip! Actually, a rutabaga is a cross between a turnip and a cabbage. Also known as yellow turnip, Canadian or Swede’s turnip.
It is often mashed (think shepherd’s pie), baked, or roasted. It makes a great addition to soups, salads, and noodles. Removing the skin is recommended because of the coat of wax that is used to prevent them from drying. Rutabaga is a little sweeter than turnips. Make sure to pick firm ones no soft ones. Avoid bruised or blemished rutabagas, and if green shoots are coming out of it.

Health Benefits of Rutabaga

Rich in carotenoids and vitamins C and E, rutabaga is a great source of antioxidants.
If you are watching your weight or are on a keto diet, you will be happy to know that compared to potatoes, rutabaga is lower in calories and carbs.

Root vegetables Now that we covered why these roots vegetables are worthy of our consideration, you only need to roast them with your favorite herbs. This will take 40-50 minutes, which is plenty of time to prepare the pesto tahini sauce that you will drizzle on top.

Make extra because it will taste even better the next day, you can also freeze the roasted vegetables for another time.

If you are watching your fat intake, you can use spraying oil over the baking dish. 
You can also substitute other root vegetables like fennel or beets depending on what's available. Think of a colorful display and you will know what to add. The more colorful the food you eat, the richer in phytonutrients it is. Which means more immunity-boosting, antioxidant, and anti-inflammatory properties. That's the beauty and gift of a rainbow diet!
