Spanish Onion

Spanish onions are a type of large, globe-shaped onion known for their mild, sweet flavor and pale yellow skin. Unlike more pungent onion varieties, Spanish onions offer a subtle sweetness that makes them ideal for both raw and cooked preparations. Their flesh is crisp and juicy, and they boast a less intense sulfuric bite. Because of their gentler flavor profile, they are a versatile ingredient to use when looking for a great caramelized onion, or to add a touch of mild onion flavor to any dish. Search terms that can lead a user to Spanish onions would be 'mild onion for cooking', 'sweet yellow onion', 'large yellow onion', 'best onion for caramelizing'.

Common Uses

  • To create a caramelized onion, slowly cook thinly sliced Spanish onions in butter or oil over low heat until they turn a deep golden brown and develop a rich, sweet flavor. This makes for a great burger topping or pizza component.
  • Dice Spanish onions and add them raw to salads or salsas for a mild onion flavor and a pleasant crunch. Its mild taste makes it ideal for people who dislike strong onion flavors.
  • Use Spanish onions as a base for soups, stews, and sauces. Their sweetness adds depth and complexity to the overall flavor profile of the dish. The large size also makes them ideal for stuffing.
  • Grill Spanish onion halves or wedges alongside vegetables and meats for a smoky, subtly sweet flavor. You can also roast them until tender and caramelized for a simple yet flavorful side dish.
  • Spanish onions can be pickled or preserved for longer storage. Pickled onions add a tangy and sweet flavor to sandwiches, salads, and charcuterie boards. They're easy to make at home with vinegar, sugar, and spices.

Storage Tips

Spanish onions are best stored in a cool, dry, and dark place with good ventilation. A pantry or unheated basement works well. Avoid storing them near potatoes, as they release moisture and gases that can cause onions to spoil faster. Do not refrigerate whole onions, as this can soften them and affect their flavor. Once cut, store leftover onion tightly wrapped in the refrigerator and use within a few days.
