Small potatoes typically take about 9 to 11 minutes to microwave until tender when placed on a microwave-safe plate in a single layer, with fork pokes to check doneness during cooking. Some recipes suggest starting with around 10 minutes, then adjusting if needed. Microwaving for about 6 minutes is also noted for baby or new potatoes, with checking at 4 minutes to adjust based on microwave wattage. The potatoes should be soft inside when fully cooked. Covering the potatoes loosely and adding a small amount of water or using a covered microwave-safe dish can help cook them evenly. After microwaving, adding butter or seasonings is common.
