Turnip and Mustard Tart
To get ahead with dinner prep, make the crust in the morning (or better yet, the day before), so you’ll be ready to assemble.
Extra-virgin olive oil
1 large turnip (about 1 pound), diced into 1/2-inch pieces
1 brown onion, diced
1 garlic clove, minced
1 bunch chard, stems removed and thinly sliced into ribbons
1 sprig thyme, leaves removed
1 buckwheat crust (via Sprouted Kitchen)
3 tablespoons Dijon mustard (I like a combination of whole grain and smooth)
Salt and pepper
4 sprigs thyme
1 cup grated gruyere
1 large egg, lightly beaten
Preheat the oven to 400 degrees.
Saute the turnips in 1 tablespoon of oil over medium low heat for 8-10 minutes, or until just beginning to turn golden. Season with a pinch each of salt and pepper. Add the turnips to a large bowl and heat another tablespoon of oil in the same pan. Add the onion and garlic; cook for 2 to 3 minutes, then add the chard, thyme, and season with a pinch each of salt and pepper. Cook for an additional 3 to 5 minutes, or until the chard is wilted. Scrape the vegetables into the bowl with the turnips.
Roll out the crust in an 11 to 13-inch circle and gently place into a tart pan. Lop off any overhang by running your rolling pin over the top. Add a piece of foil and a cup or so of beans or pie weights on top; bake for 15 minutes.
Once the vegetables have cooled slightly, add the egg and half the gruyere; mix well to combine. Pour the filling into the crust and spread in an even layer. Top with the remaining gruyere. Bake for about 25 minutes, or until the tart is just set and the top is starting to brown.
