Potatoes can be difficult to store without sprouting or turning mushy. Chef and cookbook author Sara Moulton has shared the most effective method: use a common household item that most people already have.
The Problem with Common Storage Methods
Potatoes release moisture during storage, which can soften their skin if kept in enclosed spaces like under the sink, in a cupboard, or inside a plastic bag. Light exposure causes them to turn green, sprout, and become harmful. Leaving them on a worktop is also inadvisable.
The Best Container: Paper Bag or Cardboard Box
Moulton explains: "Potatoes keep best when placed in a well-ventilated container and stored in a dry location, away from sunlight, and at temperatures between 45 and 55 degrees F [7C to 13C]." She recommends a paper bag, cardboard box, or bowl—not a plastic bag. These breathable materials absorb moisture, preventing spoilage. Plastic retains moisture, causing condensation and faster deterioration.
Where to Store Potatoes
Place the container in a cool, dark area with good airflow. Avoid high cupboards near the oven or hob, as rising heat and steam accelerate spoilage. A lower cupboard away from the sink and appliances is ideal. In a pantry, keep potatoes on a lower shelf, away from garlic and onions, which release moisture.
Storing potatoes in the fridge is not recommended, as cold temperatures break down starches, affecting texture and flavor. With proper storage, potatoes can last one to three months longer than usual, reducing food waste.
