onion and beans

ProduceFresh onions peak in late summer through fall; however, storage onions remain available year-round due to their excellent keeping qualities. Sweet onion varieties are seasonal, typically available spring through early summer.

Onions are low in calories but rich in vitamin C, dietary fiber, and quercetin, a potent antioxidant flavonoid with anti-inflammatory properties. They also contain prebiotic compounds that support digestive health.

About

The onion (Allium cepa) is a bulbous herbaceous plant native to Central Asia, belonging to the allium family alongside garlic, leeks, and chives. The edible portion is the layered underground bulb, composed of concentric rings of leaf bases filled with starches and sugars. Common varieties include yellow, red (purple), and white onions, each with distinct flavor profiles: yellow onions are pungent and sweet when cooked, red onions are milder and slightly sweet with a purplish hue, and white onions are sharper and more delicate. Raw onions contain sulfur compounds responsible for their characteristic pungency and tear-inducing properties when cut; cooking transforms these compounds into sweeter, more mellow flavors through caramelization and Maillard reactions.

Culinary Uses

Onions are a foundational aromatic in cuisines worldwide, forming the flavor base for soups, stews, sauces, and braises across European, Asian, African, and American traditions. They are sautéed as a soffritto (Italy), mirepoix (France), or holy trinity (Louisiana Creole) to build savory depth. Raw onions provide sharp, fresh bite in salsas, salads, and pickled preparations. They are caramelized for French onion soup, grilled for kebabs, roasted as a side dish, or used in curries and stir-fries. Sweet varieties like Vidalia and Walla Walla are suited for raw applications and desserts, while storage varieties tolerate prolonged cooking.
