Where it comes from

Lettuce was cultivated in ancient Egypt — depicted in hieroglyphs — and spread through the Greek and Roman worlds. European settlers brought it to the Americas, where it was grown in kitchen gardens from colonial times. The iceberg lettuce revolution of the 20th century, driven by refrigerated rail transport, made lettuce a national staple in North America. Today the diversity of lettuce varieties at grocery stores and farmers markets reflects waves of culinary influence from European, Asian, and Latin American traditions.

Varieties — Butter (Boston/Bibb) lettuce has soft, loosely cupped leaves with a mild, buttery flavor. Iceberg is crisp and watery with a very mild taste. Green leaf and red leaf lettuces are tender with a slightly more pronounced flavor. Romaine (cos) is upright and sturdy with a crisp rib — see also romaine-hearts for the inner leaves specifically.

Iceberg lettuce is essential to the classic American wedge salad; butter lettuce cups are the vehicle for Vietnamese lettuce wraps and Korean ssam (pork or beef wrapped in leaves); romaine is the defining green in Caesar salad.

In a modern kitchen — Wash and spin lettuce dry before dressing — excess water dilutes dressing and makes leaves go limp. Store clean, dry lettuce loosely wrapped in a paper towel in a bag in the crisper drawer for up to 5 days.

Buying it

Choose heads with crisp, unblemished leaves and a fresh, clean smell. Avoid any with brown spots, slimy patches, or wilted outer leaves. Heads should feel heavy for their size. Loose-leaf varieties should be bright-colored with no yellowing.

Storing it

Store lettuce unwashed in a sealed bag or container in the fridge crisper, with a paper towel to absorb extra moisture. Remove slimy or brown-edged leaves promptly to keep the rest fresh.

Keeps about 7 days in the fridge.

In season

Peak season is May–June & September–October, though it's available year-round.

Lettuce is often best in cooler spring and fall weather, with regional and greenhouse supply year-round.

Out of lettuce? Good swaps

  • Spinach — Slightly more flavor and nutrition; use 1:1 raw in salads or as a wrap
  • Radicchio — Bitter and colorful; mix with milder greens — use ¼ to ½ the amount
  • Napa cabbage — Crunchy with a mild, slightly sweet flavor; great shredded in slaws and wraps — use 1:1
