Preheat oven to 400 degrees.
Wash your beets. Cut into six wedges and place in a shallow dish. Drizzle with olive oil and season with salt and pepper. Toss to coat.
Place a piece of aluminum foil in a baking pan. Arrange the beets on the pan and top with rosemary. Fold the foil around the beets and seal tightly.
Bake until the beets are tender; about 1 hour. Open the foil carefully as steam will be released. Discard the rosemary sprigs. Season again with salt and pepper, to taste (optional).
Serve and enjoy!
