Wash beets and cut off the tops and stems. Place the beets on a large piece of aluminum foil and drizzle each beet with one teaspoon olive oil.
Wrap foil tightly to make a pouch and place on a baking tray or sheet.
Bake for 1 hour until beets are tender. Let cool for 20 minutes so that they are cool enough to handle. Peel the beets and use them as needed. Can be kept in an airtight container for a few days in the fridge.
