Per 1 medium (110g)Chef’s Secret
Caramelizing onions slowly over low heat with a pinch of salt unlocks their deep, natural sweetness and adds complex umami.
Substitutions
Shallots
Milder, more delicate flavor, great for sauces and vinaigrettes where a less aggressive onion flavor is desired.
Leeks (white parts)
Offers a milder, sweeter onion flavor, excellent in soups, stews, and braises.
Onion Powder
For dried applications or when fresh onion isn't available; provides concentrated flavor, but lacks texture.
Celery
Provides aromatic base and crunch, often used in mirepoix, but lacks onion's pungent flavor.
Buying Guide
Choose firm, dry onions without soft spots or sprouts. Store in a cool, dark, well-ventilated area.
