Ingredients
1poundbeetstrimmed (select similar sized beets, 2-3 inches in diameter)
1/2cupwater
1/4cupsherry vinegar
2tablespoonsextra-virgin olive oilplus extra for drizzling
1teaspoonfresh thyme leaves
Salt and pepper
2oranges
4ouncesbaby mixed greens or arugula
2ouncesParmesan or Pecorino Romano cheeseshaved with vegetable peeler
1/2cupwalnutstoasted and chopped coarse
Instructions
Adjust oven rack to middle position and heat oven to 400 degrees. Place 16 by 12-inch piece of aluminum foil on rimmed baking sheet. Arrange beets in center of foil and lift sides of foil to form bowl. Add water to beets and crimp foil tightly to seal. Roast until beets can be pierced easily with fork, 1 1/4 to 1 1/2 hours.
Peel beets once they are just cool enough to handle (you want them to still be slightly warm to better absorb the marinade.) Halve each beet vertically, then cut into ½-inch-thick wedges.
Whisk vinegar, oil, thyme, 1/2 teaspoon salt, and 1/4 teaspoon pepper together in large bowl. Add beets and toss to combine. Cover and refrigerate for at least 30 minutes or up to 24 hours (I marinated for 24 hours and they turned out delicious and flavorful!)
Cut away peel and pith from oranges. Holding fruit over bowl, use paring knife to slice between membranes to release segments; set aside. Arrange greens on a serving platter. Spoon beets over green and drizzle with remaining marinade. Arrange orange segments over salad and top with shaved cheese and walnuts. Season with salt and pepper to taste. Drizzle with extra oil and serve.
Notes
Canned Mandarin oranges (drained) are an option if you don't want to peel fresh oranges.
