Scrub beets and trim tops to 1 inch. Place on a large piece of heavy-duty foil. Drizzle 2 teaspoons olive oil over beets, and wrap in foil, sealing tightly. Place on a baking sheet.
Bake until tender, about 45 minutes. Open foil carefully, allowing steam to escape. Let cool.
Trim tops, peel, and cut each beet into wedges (6 if medium, 4 if small); place in a small bowl. Add remaining 2 teaspoons olive oil, salt, rosemary, and pepper; toss.
