Pleah is a Cambodian lime-cured beef salad โ thinly sliced sirloin that firms and brightens in lime juice, then gets tossed with cucumber, mint, cilantro, chili, and shallot. The whole thing comes together in 15 minutes with no stove required. That alone is reason enough to make it on a busy weeknight.
Smart swaps
- Beef sirloin: Sirloin works well here because itโs lean and slices cleanly. Flank steak or eye of round are solid alternatives โ just freeze the cut for 20 minutes first so itโs easier to slice thin.
- Fish sauce: Any good Southeast Asian fish sauce works. If you only have Thai fish sauce, use it โ the difference is subtle once the lime and sugar are in the mix.
- Fresh lime juice: Bottled lime juice wonโt cut it. The acid needs to be sharp and fresh to actually cure the beef. Use real limes.
- Red chili: A Fresno chili or a small serrano both work. If heat is a concern, leave the seeds in fewer slices rather than skipping the chili entirely โ it adds more than just heat.
The technique that matters
Slicing the beef against the grain is the single most important thing you can do here. Cut with the grain and youโll get chewy, stringy strips that the lime canโt fully penetrate in 10 minutes. Against the grain, the slices are short-fibered and tender, and the lime juice reaches every surface quickly. Aim for slices no thicker than 3mm โ if your knife skills are inconsistent, a brief stint in the freezer firms the meat up and makes thin, even cuts much easier. Dress it at the table โ a pre-dressed salad goes limp fast, and the cucumber especially loses its crunch within minutes of contact with the acidic marinade.
Common problems and fixes
- Beef stays grey and rubbery after marinating: The slices were too thick. Thicker cuts need significantly more than 10 minutes to cure through, and even then the texture suffers. Re-slice thinner next time, or pound the slices briefly between plastic wrap.
- Dressing tastes flat: Fish sauce and lime juice both vary in intensity by brand. If the salad tastes dull, add fish sauce in small increments first โ it usually needs salt before it needs more acid.
- Everything is too wet and the salad pools at the bottom: Cucumbers release water fast once sliced. Pat them dry with a paper towel before adding them to the bowl, especially if theyโve been sitting out.
- Too sour to eat: A pinch more sugar fixes this faster than adding more beef. Stir it in and let it dissolve for 30 seconds before tasting again.
- Herbs wilt and turn dark: The lime juice will bruise delicate herbs if they sit in it. Add mint and cilantro right before serving, not during the beef marinating step.
Storage and make-ahead
This salad does not store well once assembled โ the cucumber softens, the herbs darken, and the beef continues to cure and tighten in the fridge. If you want to get ahead, slice the beef and mix the lime juice, fish sauce, and sugar separately; keep both refrigerated for up to 4 hours. Prep the vegetables and herbs and store them dry in a covered bowl. When youโre ready to eat, combine the beef with the dressing for 10 minutes, then toss everything together. Leftovers are edible the next day but noticeably softer โ the flavors will still be there, the texture wonโt.
Pleah (Cambodian Lime-Cured Beef Salad)
Ingredients
- 500 grams beef sirloin Thinly sliced against the grain for tenderness
- 3 tablespoons fresh lime juice Key ingredient for curing the beef
- 1 tablespoon fish sauce Preferably Cambodian fish sauce for authenticity
- 1 teaspoon sugar To balance the flavors
- 1 cup cucumber Thinly sliced
- ยฝ cup mint leaves Fresh, roughly chopped
- ยฝ cup cilantro With stems, roughly chopped
- 1 piece red chili Seeded and finely sliced
- 1 unit shallot Thinly sliced
Instructions
- In a large mixing bowl, combine the thinly sliced beef with fresh lime juice, fish sauce, and sugar. Use your hands or a mixing spoon to ensure each slice is evenly coated. Allow it to marinate for about 10 minutes, during which the beef will begin to 'cook' and change color.
- Add the thinly sliced cucumber, mint leaves, cilantro, red chili, and shallots to the marinated beef. Toss gently to combine, distributing the flavors evenly throughout the dish.
- Taste and adjust seasoning if needed, adding more lime juice, fish sauce, or sugar to achieve a balanced flavor profile.

Common questions
Is the beef actually safe to eat if itโs only marinated for 10 minutes?
Yes, with important caveats. The lime juice changes the color and texture of the outer surface of the beef, but it does not sterilize it the way heat does. Use the freshest beef you can find, buy from a trusted source, and slice it yourself rather than using pre-packaged thin-sliced meat that has had more handling.
Can I use a different protein instead of beef?
Thinly sliced raw fish โ such as snapper or sea bass โ works well and cures even faster than beef. Cooked shrimp is another practical option if youโre not comfortable with raw protein; just reduce the marinating time to 2โ3 minutes so it doesnโt turn rubbery.
How thin does the beef actually need to be?
Aim for about 3mm or roughly the thickness of a coin. Thinner than that and the beef can over-cure and turn chalky; thicker and the center stays raw-tasting and chewy even after 10 minutes in the lime juice.
Do I need to use a specific type of cucumber?
Persian or English cucumbers are the best choice because they have thin skin, small seeds, and less water than standard field cucumbers. If youโre using a regular cucumber, scoop out the seeds with a spoon before slicing to cut down on excess liquid.
Can I make this without fish sauce to keep it vegetarian?
A good-quality soy sauce or tamari gets you most of the way there in terms of saltiness, but the umami depth will be different. Adding a small amount of seaweed-based seasoning or a few drops of liquid aminos alongside the soy sauce helps close that gap.
My shallot tastes harsh and sharp โ what can I do?
Soak the sliced shallot in cold water for 5 minutes, then drain and pat dry before adding it to the salad. This pulls out some of the sulfur compounds that make raw shallot pungent without removing its flavor entirely.
