Which Vegetables Tolerate Countertop Storage Longest? Room-Temperature Shelf Life Compared
Whole, unwashed onions, garlic, winter squash, sweet potatoes, and firm potatoes usually tolerate countertop storage longer than leafy greens, tomatoes, cucumbers, or cut vegetables. Their dense structure and relatively low surface moisture slow softening and microbial spoilage, especially in a cool, dry, shaded, well-ventilated spot.
