Notes

For best texture, slice potatoes thin so they finish tender within the 6-7 hour low cook time. Refrigerate leftovers in a sealed container for up to 3 days; reheat in the microwave or in a covered pot until hot. Freezing is not recommended because potatoes can soften further after thawing. Dietary swap: use a lower-sodium cream of mushroom soup and reduce added salt to keep flavor while lowering sodium.
