Raw or roasted Onions gives Salad crunch and earthy flavor. A stand-in should offer a similar bite and pair well with the dressing.

adjustment for this dish
Shallots swap at 0.75 cup per cup and have about 40% less sulfur than yellow onion, so the ice-water soak drops from 15 minutes to 5 — any longer and they lose the crunch that balances fresh leaves. Slice paper-thin and toss with vinaigrette immediately because shallots absorb dressing acid twice as fast.
02
Carrots
10.0best for salad1 cup : 1 cup
Sweet and aromatic when diced and sauteed; classic mirepoix swap in soups
10.0
adjustment for this dish
Carrots go in 1:1 and bring sweet crunch instead of sulfur bite, so add 1 extra teaspoon acid (lemon or vinegar) to the dressing to keep the balance. Shred on the large holes or cut into matchsticks; skip the ice-water soak — carrots don't need the sulfur pull and soaking leaches their beta-carotene into the bowl.
03
Leeks
6.7best for salad1 cup : 3/4 cup
Stronger flavor, use slightly less
6.7
adjustment for this dish
Leeks swap at 0.75 cup but raw leek is fibrous, so use only the pale-green hearts sliced 1/16 inch thin. Soak 20 minutes in ice water (5 minutes longer than onion) to soften the fibers and chill for crunch. Drizzle dressing just before serving because leeks wilt faster than onion and coat unevenly once limp.

Fennel
6.71 cup : 1 cup
Mild anise when raw, sweet onion-like cooked
6.7
adjustment for this dish
Fennel replaces 1:1 and brings a celery-anise crunch that survives an acid-based emulsify better than onion. Shave on a mandoline at 1/16 inch, toss with vinaigrette, and serve within 10 minutes — fennel oxidizes faster than onion and turns grey at the edges, dulling the fresh visual of the bowl.
05
Celery
6.71 cup : 1 cup
Aromatic base vegetable, milder but similar role
6.7
adjustment for this dish
Celery swaps 1:1 by volume but contributes pure crunch rather than flavor, so double the aromatics in the dressing — fresh herbs, minced garlic, or extra mustard to emulsify. Slice on the bias at 1/8 inch and chill 10 minutes in the bowl before you drizzle, so the coat of vinaigrette grips the curved surface instead of beading off.

Cabbage
6.71 cup : 1 cup
Mild sweet bulk for braises and stews when sauteed; won't build the same aroma base

Diced bell pepper adds sweetness and crunch; good aromatic base in stir-fries

technique for salad
technique
Raw onions in a salad deliver bite through allyl propyl disulfide, and that compound peaks within 10 minutes of slicing — so prep the onion last and dress the bowl immediately, or the flavor oxidizes and turns harsh. Slice to 1/16 inch on a mandoline, soak in ice water for 15 minutes to pull out 30% of the sulfur punch, then pat bone-dry so the vinaigrette will emulsify rather than skid off wet rings.
Toss with fresh leaves and 2 tablespoons dressing per 4 cups greens; any more and the acid will wilt the onion into limp strands within 5 minutes. Drizzle, don't pour, and balance with something sweet like pear to soften the onion's edge.
Unlike onions in soup where long simmer tames them, the salad version lives or dies on that chill-and-crunch window. Serve within 20 minutes of dressing so the coat of vinaigrette stays bright and the onion keeps its snap.
pitfalls to avoid
watch out
Avoid dressing raw onion more than 20 minutes ahead — the acid in the vinaigrette wilts the rings into limp strands and kills the crunch you wanted.
watch out
Don't skip the ice-water soak; unsoaked sliced onion dominates the bowl and overpowers the fresh leaves and delicate coat of drizzle.
watch out
Reduce to 2 tablespoons dressing per 4 cups greens when onions are present, or excess acid pulls water from the onion and dilutes the emulsified vinaigrette.
watch out
Chill the sliced onion separately until the final toss, because warm onion in a cool bowl sweats and breaks the balance between crunch and dressing.
watch out
Don't slice thicker than 1/16 inch on a mandoline; thick raw rings won't coat properly and deliver bites of pure sulfur instead of balanced flavor.
