Cambodia food guide
What Khmer cuisine actually is, the dishes worth eating, and where to find them in Phnom Penh and Siem Reap.
Cambodian food is underrepresented in the international conversation about Southeast Asian cuisine. It gets overshadowed by Thailand and Vietnam — which is unfair, because Khmer cooking occupies a genuinely distinct flavour space: fermented, smoky, palm-sweet, and built around the freshwater fish that come from the Tonlé Sap, one of the world's great inland fishing lakes.
This is not a guide to the whole country. It covers the food itself — what it is, what makes it Khmer, and where in Phnom Penh and Siem Reap you can eat the real version rather than the tourist adaptation.
What makes Khmer food Khmer
Three things define Cambodian cooking more than anything else:
Kroeung — the aromatic spice paste that underpins most Khmer dishes. Made from lemongrass, galangal, kaffir lime, turmeric, shallots, and garlic, ground fresh and used as the base of curries, stir-fries, and marinades. The ratios and additions vary by dish and family; no two kroeungs are quite the same.
Prahok — fermented mud fish, Cambodia's defining condiment. Intensely savoury and funky in its pure form, used more subtly in cooking as a seasoning that gives Khmer dishes their depth. The equivalent in Khmer cooking to fish sauce in Vietnamese or shrimp paste in Thai — but its own thing, darker and more complex.
Tonlé Sap fish — the Tonlé Sap lake system is one of the world's largest freshwater fisheries, and freshwater fish is the protein that defines Cambodian food. Catfish, snakehead, trey riel — these are the animals around which the cuisine was built, not the ocean fish that define Thai and Vietnamese coastal cooking.
The essential dishes
Kuy Teav — Khmer noodle soup
The Cambodian equivalent of pho. Rice noodles in a clear pork or beef broth, with bean sprouts, lime, fresh herbs, and your choice of additions. Eaten at breakfast, primarily from street stalls. Every Cambodian family has a preferred stall; the best versions have been running for decades. The broth is lighter and more delicate than pho.
Amok Trey — steamed fish curry
Fish (usually freshwater) steamed in a banana leaf cup with coconut cream, kroeung, and eggs — lightly set, fragrant, subtle. The single most-cited dish of Cambodian cuisine, and for good reason. The tourist version is often too sweet and too thick; the real version is a mousse-like custard with the depth of the kroeung doing the work. Order it at Mahob or Yum Bay for the fine-dining version, or look for it at local Khmer restaurants where the banana leaf is the real thing.
Lok Lak — stir-fried beef
Cubed beef wok-tossed in oyster sauce and soy, served on a bed of lettuce and tomatoes, with a raw egg and a lime-black pepper dipping sauce. A French colonial influence is visible here — the dish was shaped by the colonial period and has been adopted completely into the Cambodian canon. The pepper sauce (tuk meric) is the key; Kampot pepper, if you can get it, is the reason to care.
Bai Sach Chrouk — pork and rice
Slow-grilled coconut-marinated pork over charcoal, served with broken rice and pickled cucumber and daikon. A Phnom Penh morning food, eaten at plastic stools on the pavement. The quality of the charcoal-grilled pork is what distinguishes a good version from a generic one.
Nom Banh Chok — Khmer noodles with green fish curry
Fresh, fermented rice noodles served cold with a thin, green kroeung-and-fish curry sauce, topped with raw vegetables and fresh herbs. A distinctly Cambodian dish — the fermented noodles and the light curry sauce have no direct equivalent in neighbouring cuisines. Found at morning markets across the country; the Siem Reap version has a distinct regional character.
Prahok Ktis — fermented fish dip
Prahok (fermented fish paste) cooked with minced pork, coconut cream, and kroeung into a thick, deeply flavoured dip, served with raw vegetables and rice crackers for dipping. The dish that tests a visitor's willingness to engage with Cambodian food on its own terms — pungent, rich, and genuinely extraordinary when made well.
Where to eat in Phnom Penh
For serious Khmer cooking: Yum Bay (six-seat tasting menu around a charcoal hearth, BKK1 — book on the first of the month) and Mahob (royal Khmer in a 1930s villa, Daun Penh). These are the two best arguments for what Khmer food can be at the highest level.
For traditional, neighbourhood Khmer: Sambok in Toul Tom Poung for slow-cooked market-driven stews; Phka Slaa for a garden kitchen with river fish and banana-flower salads; Sambo Fish for grilled freshwater fish on Riverside.
For late-night modern Khmer: Ratri in BKK1 — a kitchen that takes the cuisine seriously and opens when others have closed.
For street food and breakfast: The night markets near Orussey market and the morning stalls along Sisowath Quay. Kuy teav and bai sach chrouk are the two things to find before 9am.
Where to eat in Siem Reap
Siem Reap is a tourist city and its restaurant scene reflects that — there is a tourist corridor around Pub Street and the Old Market that serves a generic approximation of Khmer food. The real eating happens away from that strip.
The night market and the local restaurants around Phsar Chas (Old Market) on the east side of the river have more genuine Cambodian cooking. The proximity to the Tonlé Sap lake means freshwater fish is particularly good here — fish amok and grilled river fish in Siem Reap should taste different from the Phnom Penh version because the fish is closer. Look for that distinction.
Siem Reap also has a growing number of younger Cambodian-chef-driven restaurants that are doing serious work with the local cuisine — a reflection of the same revival visible in Phnom Penh.
Frequently Asked
What is Khmer food?
The traditional cuisine of Cambodia — built around freshwater fish from the Tonlé Sap, rice, fermented fish paste (prahok), and kroeung aromatic spice paste. Gentler and less chili-forward than Thai food; similar in some ways to Vietnamese but distinctly its own.
What are the must-try Cambodian dishes?
Kuy teav (noodle soup, the national breakfast), amok trey (fish steamed in banana leaf with coconut and kroeung), lok lak (stir-fried beef with Kampot pepper sauce), bai sach chrouk (slow-grilled pork and rice), and nom banh chok (cold noodles with green fish curry sauce). These five give you a complete picture of the cuisine.
How is Cambodian food different from Thai and Vietnamese?
Less chili heat than Thai; less emphasis on fresh-herb-as-primary-flavour than Vietnamese. The defining notes are prahok (fermented fish paste), palm sugar, smoke, and the aromatic depth of kroeung. The Tonlé Sap freshwater fish focus is not shared by either neighbour.
Where is the best Khmer food in Phnom Penh?
For fine dining: Yum Bay (six-seat tasting menu, BKK1) and Mahob (royal Khmer, Daun Penh). For neighbourhood cooking: Sambok (Toul Tom Poung), Phka Slaa (Riverside), Sambo Fish (Riverside). See the full Khmer restaurant guide.
Is Cambodian food spicy?
Less than Thai food. Traditional Khmer cooking uses chilies more subtly — the heat is present but not the defining note. Kuy teav, amok, and nom banh chok are mild enough for most palates. Some dishes, particularly the more regional or fermented preparations, can be more assertive, but Cambodia is not a cuisine that leads with heat.
