A recent article about leafy tops of certain root vegetables on The Kitchn had me reconsidering my habit of blithely chucking them, especially after my attention snagged on a link for
Grilled Cheese with carrot top pesto. I happen to have a thing for unconventional pestos, so this weekend when I found myself with a nice bunch of organic carrots, an unruly shock of greens still attached, I seized the opportunity to try the pesto recipe out. The carrots went towards a batch of carrot soup, a standard of mine. Usually I spice it with a big pinch of ras el hanout, but with good, sweet carrots and a zingy pesto in the mix, I just let the carrot flavor speak for itself this time. The pesto, which I slathered on toasted baguette slices, turned out to be a pretty awesome pairing with the soup - the acidity of the lemon juice and the mildly bitter flavor of the greens added a lovely balance to the bowl. I'll certainly be saving shorn carrot tops from now on, I love the idea of buying two vegetables for the price of one!
Roasted Carrot Soup with Carrot Top Pesto Crostini
Makes 1 large serving or 2 modest servings
*1 bunch (1 lb) organic carrots with greens attached
*Half of a small white potato
*4 cloves garlic, 2 minced
*1 tablespoon butter
*1 cup vegetable stock
*1 cup water
*1/4 cup extra virgin olive oil
*Juice of 1/2 lemon
*1 heaping tablespoon grated asiago cheese
*S&P
*Slices of good crusty bread
Heat oven to 420 degrees. Cut the tops off of the carrots. Tear enough of the leafier parts from the harder stems to equal two heaping cups. Wash and dry the greens well, and set them aside. Peel the carrots and potato and dice into 1 inch pieces. Toss with olive oil, salt and pepper (I use a harissa-infused olive oil, which adds a hint of heat) and roast in the oven for 20 minutes. Stir the vegetables and reduce the heat to 300; roast another 10 minutes or so.
Meanwhile, in a pot, melt the butter and saute the minced garlic. Add the stock and water, a sprinkle of salt and pepper (and red pepper flakes, if you're not using a spicy olive oil and would like a little heat). Add the roasted carrots and potatoes and simmer until the vegetables are all very soft. Blitz the contents of the pot in a blender or with an immersion stick, and then strain the soup with a sieve to get it as silky as possible. I like a thicker soup, but you can thin it with a little water or stock if you prefer. Season to taste.
For the pesto crostini, brush one side of the bread slices with a little olive oil, then place on a cookie sheet and flick on the broiler for a few minutes until the slices are toasted. Blend the garlic cloves, carrot greens, lemon juice, asiago and pinches of S&P together in a small food processor, and then drizzle in the olive oil until it is of pesto consistency. Spread on the toasted bread and serve the crostini with the soup.
Makes between a third and a half-cup of pesto.
NOTE: There is a fair amount of discussion on the internet about the supposed toxicity of carrot tops, but that claim appears to be totally a myth. From reading very reputable sources, I have come to the conclusion that carrot greens are NOT toxic, but may cause mild allergic reactions in a small segment of the population. In any case, I ate my carrot greens and loved 'em, but to eat or not to eat is up to you! I say go for it. Free greens with purchase of any organic carrots.
