Substitutions · 18 dishes here use it

Out of lettuce

Structure and water, and it is worth being fussy about. Dry it properly or dressing slides off and pools, which is the single most common salad failure.

Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.

3 of the 18 dishes here that mention lettuce list it as optional — 17% of them. In those, the correct substitution is nothing.

What to reach for

Instead · 1

any other salad green — arugula, spinach, mizuna

one for one by volume

What it gets you
Leaves in a bowl, dressed the same way.
What it costs you
Crunch, mostly. Arugula is peppery and spinach is soft, so both want a firmer dressing and something crisp added.

Instead · 2

cabbage, sliced very thin

half the volume

What it gets you
Crunch that lasts, and a salad that can be dressed an hour ahead without collapsing.
What it costs you
Delicacy. This is a slaw, and it should be dressed like one.

Instead · 3

cucumber and celery, sliced

one for one by volume

What it gets you
Cold, wet crunch for a sandwich or a bowl.
What it costs you
The leaf, and the way a leaf carries dressing. This is a chopped salad now.

Where you can just leave it out · 3

These dishes list lettuce as optional. They were written to work without it, so no ratio is needed and nothing has to be bought.

Where the swap will be tasted · 2

These need it and are short enough that nothing hides: 4 required ingredients or fewer, which makes lettuce a quarter of what is in the pan. Make the swap a decision rather than a repair.

Check what else is in the pan

The company lettuce keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
