med onions

ProduceYear-round. Onions are harvested in late summer through fall but store exceptionally well, maintaining quality for 4-6 months under proper cool, dry conditions, ensuring consistent availability throughout the year.

Medium onions are a good source of vitamin C, dietary fiber, and quercetin (a flavonoid antioxidant); they are low in calories (approximately 45 calories per medium onion) and contain prebiotic compounds that support digestive health.

About

Medium onions are bulbous vegetables of the Allium cepa species, characterized by a papery golden or reddish-brown outer skin encasing layers of white or pale purple flesh. The term "medium" refers to size classification, typically weighing between 5-7 ounces (140-200 grams). Medium onions represent the most versatile size for general culinary applications, offering a balance between pungent sulfur compounds when raw and sweeter, caramelized notes when cooked. The flavor intensity varies by variety and storage duration, with yellow onions being the most common and providing a balanced sweet-savory profile, while red onions offer milder, slightly sweet characteristics with purple pigmentation.

Culinary Uses

Medium onions are foundational aromatic vegetables in virtually all global cuisines, serving as the base for sauces, stocks, soups, and stir-fries. They are raw in salads, salsas, and relishes; caramelized for gratins and French onion soup; roasted whole or halved; and pickled for preservation and condiments. Medium onions are ideal for dicing into uniform pieces for even cooking, making them the preferred size for mirepoix (French vegetable base), soffritto (Italian), and similar foundational preparations. Their size allows efficient hand-chopping while providing enough volume for substantial dishes.

Forms & Preparations

Diced — Cut into uniform cubes (¼ to ½ inch), the standard preparation for sautéing as an aromatic base or in raw applications.
Sliced — Cut into rings or half-moons for caramelization, grilling, frying into crispy strings, or serving raw in salads and burgers.
Minced — Finely chopped into small pieces for quick dissolution into sauces, dressings, or when a subtle onion presence is desired without visible chunks.
Whole roasted — Left intact or halved and roasted with skin until soft and caramelized, then peeled and served as a vegetable or component in composed dishes.
Julienned — Cut into thin matchstick-like strands for stir-fries, quick cooking, or dishes where rapid and even cooking is desired.
Pickled — Sliced and preserved in vinegar-based brine for use as a condiment, garnish, or ingredient in ceviche and Latin American preparations.

Substitutes

Unknown — Use in equal volume; shallots are smaller and more delicate with subtle garlic notes. Better for refined sauces; less suitable for caramelization due to higher moisture and quicker burning.
Unknown — Use 1.5 times the volume; milder and sweeter flavor with less pungency. Requires more thorough washing. Works well for soups and braises but lacks the intensity for sauces.
Unknown — Use 6-8 cloves per medium onion; much more pungent and assertive. Suitable only when onion's sweetness is not essential; will dominate the dish.
Unknown — Equal substitution by volume; sharper, more astringent flavor with thinner, more papery skin. Better for Mexican and Southwestern dishes; less versatile for caramelization.
