cebolla mediana

ProduceYear-round. Onions are storable crops with excellent shelf life when kept cool and dry; peak harvest occurs in late summer and fall, but commercial availability and quality remain consistent throughout the year in most regions.

Onions are low in calories while providing vitamin C, B vitamins, and quercetin, a flavonoid with antioxidant properties. They also contain inulin, a prebiotic fiber that supports digestive health.

About

Cebolla mediana refers to a medium-sized onion, typically weighing 150-250 grams, from the genus Allium cepa. Onions are bulbous vegetables native to Central Asia and cultivated worldwide for thousands of years. The bulb consists of concentric layers of modified leaf bases rich in sugars and sulfurous compounds, enclosed in papery outer skin (tunic) in colors ranging from yellow, white, or red depending on variety. The flavor profile ranges from sharp and pungent when raw to sweet and caramelized when cooked, as heat breaks down sulfur compounds and converts sugars through the Maillard reaction.

Medium onions are the standard culinary size, offering balanced proportions for dicing, slicing, and roasting without excessive waste or cooking time variation within a single bulb. Common varieties include yellow (most common, mildly sweet), white (crisp, slightly sharper), and red/purple (sweeter, milder).

Culinary Uses

Cebolla mediana serves as a foundational aromatic across global cuisines, particularly in Spanish, Latin American, and Mediterranean cooking. It is essential to sofrito and mirepoix-style flavor bases, where diced onions are sweated in fat to build umami depth. Medium onions are ideal for caramelization, roasting whole or halved, pickling, and use in soups, stews, salsas, and rice dishes. Raw applications include slicing for salads, sandwiches, and fresh salsas. The medium size suits individual portion roasting and provides optimal balance between cook time and sweetness development without becoming overly soft.

Forms & Preparations

Diced — Cut into small cubes, standard preparation for sofrito, soups, and salsas
Sliced — Thinly or thickly sliced for raw applications, caramelization, and layered cooking
Whole/Halved — Roasted whole or split in half for individual servings or use in stock-making
Caramelized — Slowly cooked over low heat until deeply browned and sweet, used as base for soups or side dish
Pickled — Sliced and preserved in vinegar brine, common accompaniment in Latin American and Spanish cuisine
Minced — Finely chopped into small pieces for even distribution in raw salsas and salads

Substitutes

Unknown — Use approximately 1.5 shallots per medium onion for milder, slightly sweet flavor; best in applications where onion prominence is less desired
Unknown — If medium yellow onion unavailable, use white onion at 1:1 ratio; expect slightly crisper texture and more pungent raw flavor
Unknown — Substitute 1:1 for sweeter, milder profile; adds visual color to raw preparations but may discolor acidic dishes
Unknown — Use white and light green parts only at 2:1 ratio; provides more delicate onion flavor, better suited to refined dishes than robust stews
Unknown — Not ideal for cooking applications requiring caramelization; use primarily as raw garnish or in quick-cooking dishes at 3:1 ratio
