The absolute best shallot substitute is a 50/50 blend of onion and garlic. Take half the amount of shallot called for in your recipe—say, one tablespoon—and use half a tablespoon of finely diced onion and a tiny, tiny pinch of minced garlic. This is the nuclear option of replacement.
Why does it work? Because shallots are basically nature’s cheating device. They taste like a union between the pungent might of an onion and the spicy warmth of garlic, but without the drama. Your friend’s tongue won’t know the difference, but your secret ingredient stash will thank you.
Just remember: garlic is potent. A little goes a very long way. Unless you want your vinaigrette to taste like a vampire apocalypse, be stingy with the clove.
The Scallion (Green Onion) Gambit
Okay, let’s talk about the scallion, also known as the green onion. This is your “I ran out of ideas five minutes ago” substitute. Scallions are extremely mild, almost watery, and they’re missing that subtle garlic note. But if you’re making a fresh salsa, a mild dressing, or a garnish, they’ll do the job with a smile.
The trick here is to use the white and light green parts only. The dark green part is tough and grassy—save it for stock or a compost bin. Use about one and a half times the amount of shallot called for, because scallions are shy and won’t shout as loud.
Fun fact: scallions and shallots are not even related in the way you think. Shallots are a type of onion. Scallions are just baby onions pulled early. It’s like comparing a toddler to a teenager—both are annoying, but one is definitely more sophisticated.
