Trim off the thin, stringy part of the root. Also, trim the greens, leaving about 1 inch of the stems attached to prevent them from bleeding too much juice while roasting.
Wash and scrub the beets to remove any dirt. Next, pat them dry with a paper towel.
Place the beets on a large piece of aluminum foil. Drizzle the olive oil over the beets and rub to evenly coat them. Then, season them with salt, pepper, and optional herbs to taste.
Add another piece of aluminum foil over the beets and wrap them in the foil packet.
Place the foil-wrapped beets on a baking sheet and bake them at 400°F for 50-60 minutes, depending on the size. They are done when easily pierced with a fork.
Once done, let the beets cool slightly. Then, rub off the skins using your hands or a paper towel.
Leave the beets whole or chop them into small pieces. After that, serve or store them in an airtight container in the refrigerator to enjoy later.
