What is it?

A sweet, aromatic bulb containing sulfur compounds which break down into caramelized sugars upon heating. Slicing along the fiber helps maintain structural integrity during simmering.

Substitution Guide

✅ Best Substitute

Sweet Onion

Milder raw heat and cooks down slightly faster; works beautifully in Oyakodon.

⚠️ Acceptable

Shallots

More concentrated, delicate flavor with a hint of garlic aroma; delicious but changes the traditional profile.

🚫 NEVER Use

Red Onion

Red onion stays sharp when cooked. It also bleeds colour into a clear broth.
