Shallots
Also known as: Xiao Cong, Asian Shallots, Allium cepa var. aggregatum, French Shallots
Shallots occupy a specific niche in Chinese cooking — sweeter and more delicate than onions, more complex than scallions, they are used both as a fresh aromatic and, when fried until crispy, as one of the great condiments of Southeast Asian and southern Chinese cooking.
Crispy fried shallots (zha cong su) scattered over noodle soups, congee, and braised dishes add texture, sweetness, and a deep, caramelized onion flavor that transforms even the simplest preparation.

Traditional Medicine Perspectives
Traditional Chinese Medicine
Shallots share the TCM profile of other alliums — warm, acrid, and associated with the Lung and Stomach meridians. They are used to release the exterior, warm the middle, and move Qi. Shallots are considered gentler and more tonifying than garlic, making them suitable for people with more sensitive constitutions who need warming without excessive stimulation.
Modern Scientific Research
Shallots contain high concentrations of quercetin and other flavonoids — research indicates shallots have among the highest antioxidant content of any allium.
They contain allicin precursors similar to garlic and onions, with associated antimicrobial and anti-inflammatory properties.
The caramelization that occurs during frying creates additional antioxidant Maillard reaction products.
Cultural History
Shallots have been cultivated across Asia for millennia and are particularly important in the cooking of southern China, Vietnam, Thailand, Malaysia, and Indonesia.
In Cantonese and Teochew cooking, fried shallots are a finishing condiment used with the same casual confidence as black pepper in a Western kitchen. In Shanghainese cooking, shallot-infused oil is a foundational flavoring.
The small, elongated Asian shallot — more pungent and less watery than European varieties — is the preferred type across Chinese and Southeast Asian cuisines.
Culinary Uses
Use raw in dressings and cold preparations where a milder onion flavor is wanted.
Slice thinly and fry until crispy for a finishing garnish over noodles, congee, and braised dishes. Use in aromatics bases for Cantonese and Shanghainese preparations.
Crispy fried shallots add texture, sweetness, and deep caramelized flavor to even the simplest preparation.
Infuse in oil for shallot oil. Use in Vietnamese and Southeast Asian preparations.
Preparation Methods
For crispy fried shallots: slice thinly and evenly (a mandoline helps). Start in cold oil, bring to medium heat, and fry slowly until deep golden — this produces crispy results without burning.
Drain on paper towels; they crisp further as they cool. Store in an airtight container for up to a week.
