3-Step Execution Protocol

Preheat & Prep

Add whole baked russet potatoes (no foil, no water) (6–8 medium russet potatoes (8–10 oz each), scrubbed and thoroughly dried, pricked all over with a fork, rubbed with olive oil and kosher salt; loaded directly into a dry 6-qt crock in a single crowded layer with no liquid, no foil, and the lid seated tight) to the slow cooker. Set to LOW (7–8 hrs) or HIGH (4–5 hrs).

Slow Cook

Cook for 7–8 hours on LOW. Keep lid on; do not stir unless specified.

Check & Rest

A cake tester or thin paring knife slides into the thickest potato with the same feel as pushing through soft butter — no resistance, no snap in the centre; the skins have gone leathery and matte with visible salt crust, and the potato yields like a bean bag when squeezed with tongs. Rest for 5 minutes before serving.

Verification Basis & Testing Rig

Idaho Potato Commission "Slow Cooker Baked Potatoes" published method (LOW 7–8 hrs / HIGH 4–5 hrs for medium russets, no foil, no water); Crock-Pot 6-Qt Set & Forget recipe archive "Baked Potatoes" (LOW 7–8 hrs); no probe target — doneness is a cake-tester slide-in test typical for whole starchy vegetables, so internalTempTargetF is intentionally omitted per HR-2.

Pro Tip: Skip the foil wrap and skip adding water — both are holdovers from oven baked-potato recipes that do the exact wrong thing here. Foil traps steam against the skin and gives you soggy, wet potato instead of the dry-fluffy interior a russet is capable of, and any added liquid in the pot pools at the bottom and boils the underside instead of steaming the whole potato evenly in its own moisture.
