Peel and cut beet into ½-inch cubes. Wrap in foil and bake until soft and easily pierced with a fork, about 40 minutes. Let cool completely.
In the work bowl of a food processor, combine ¼ cup cubed beets, chickpeas, tahini, lemon juice, lemon zest, garlic, salt, pepper, and 1 tablespoon cold water. Process until mixture is smooth and creamy, 1 to 2 minutes. With food processor running, pour olive oil through chute in a slow, steady stream until combined. Serve immediately. Garnish with olive oil and pepper, if desired. Refrigerate in an airtight container for up to 3 days.
