Roasted Turnips with Balsamic Vinegar
(2-3 servings, recipe can be doubled. Recipe created by Kalyn, with possible inspiration from
this recipe.)
2 large turnips
1 T olive oil
1 T balsamic vinegar
additional 1 tsp. balsamic vinegar for finishing
Salt and freshly ground black pepper to taste
Preheat oven to 425 F for convection or 450 F for regular oven. Peel turnips with knife, then cut into pieces about 1 inch square. Whisk together olive oil and balsamic vinegar and toss with turnips, then spread in single layer in roasting pan. Roast turnips 25-30 minutes, or until slightly browned and softened.
Remove turnips from oven and place into serving bowl. Toss with additional 1 tsp. balsamic vinegar, season to taste with salt and freshly ground pepper, and serve immediately. (I didn't use much salt and only a tiny bit of pepper.)
