Lemon Cucumber
Lemon cucumber is a round, tennis-ball-sized cucumber variety (Cucumis sativus) with pale yellow skin that resembles a lemon in shape and color, though it tastes nothing like citrus. The flesh is pale green, crisp, and slightly sweeter and less bitter than standard slicing cucumbers, with thin, tender skin that rarely needs peeling.
Varieties
Lemon cucumber is a true heirloom cucumber variety, not a cross between a cucumber and a lemon, and it is unrelated to the citrus fruit despite the resemblance in color and shape.
Buying tips
Choose ones that are pale yellow to yellow-green and firm, about the size of a lemon or slightly larger. Avoid any that have turned deep golden yellow or feel soft, both signs of overripeness that bring on a bitter, seedy interior.
Substitutes
Persian cucumber — 1:1 by weight
Similar thin skin, small seeds, and crisp texture; closest substitute for both raw and pickled uses.
English (hothouse) cucumber — 1:1 by weight
Slightly less sweet and with a bit more moisture; seed and pat dry if using in salads to avoid a watery result.
Kirby cucumber — 1:1 by weight
Firmer flesh and thicker skin than lemon cucumber, so peel it if the recipe depends on tender skin; works well pickled.
Standard slicing cucumber, peeled and seeded — 1:1 by weight
More bitter skin and larger seeds, so remove both; flavor is noticeably less sweet than lemon cucumber.
Storage
Store unwashed in the refrigerator crisper drawer, ideally in a perforated plastic bag, for up to a week. Lemon cucumbers have thinner skin than standard cucumbers and bruise or soften faster, so keep them away from heavier produce.
How to use
Eat raw in salads, sliced onto sandwiches, or cut into wedges for dipping since the skin is thin enough to skip peeling. They hold up well in quick pickles and refrigerator pickles because the flesh stays crisp longer than watery slicing cucumbers. Their round shape also makes them good for hollowing out and stuffing.
What it pairs with
Pairs well with feta, fresh dill, mint, and a simple vinaigrette, and balances richer dishes like grilled fish or lamb. Works nicely alongside tomatoes and red onion in a summer salad.
Nutrition
Like other cucumbers, lemon cucumbers are around 95% water and low in calories, with small amounts of vitamin K and vitamin C. Their slightly higher natural sugar content compared to slicing cucumbers gives them a milder, sweeter taste rather than added nutritional value.
FAQ
Do lemon cucumbers taste like lemons?
No, the name refers only to their round shape and yellow color. The flavor is a mild, slightly sweet cucumber taste, generally less bitter than standard cucumbers.
Do you need to peel lemon cucumbers?
Usually not. The skin is thin and tender, similar to a Persian cucumber, so most people eat it as is unless the cucumber has grown overripe and the skin has toughened.
Why are my lemon cucumbers bitter?
Bitterness usually shows up in cucumbers left on the vine too long or grown under water stress. Harvest them while still pale yellow, before they deepen to a strong golden color.
Can lemon cucumbers be used for pickling?
Yes, their firm, crisp flesh holds up well in both quick refrigerator pickles and canned pickles, and their small size makes them easy to pickle whole or halved.
