How Long to Cook Whole Beets (Skin On, For Peeling) in the boiling
Specification: Medium red beets (2–3 inch), tops trimmed to 1 inch, roots intact, unpeeled, started in cold water covering by 2 inches
3-Step Execution Protocol
Preheat boiling to 212°F (100°C), reduce to steady simmer once boiling. Prepare whole beets (skin on, for peeling) (Medium red beets (2–3 inch), tops trimmed to 1 inch, roots intact, unpeeled, started in cold water covering by 2 inches).
Cook for 30–45 min (30 min small / 40 min medium / 45+ min large). Do not flip; allow surface to develop undisturbed.
A paring knife slides all the way in and back out with no resistance at the center, and the skin loosens visibly around the tops when the beets are lifted from the water. Rest for 10 minutes before serving.
