Eating Your Way Through Cambodia: Khmer Food for Thailand-Based Travellers

If you know Thai food, you arrive in Cambodia with useful instincts and one wrong assumption. The instincts: rice is the centre of the meal, markets are where food culture lives, soup for breakfast is perfectly normal, and the best eating is often at the simplest-looking place with the busiest kitchen. The wrong assumption is that Khmer food is a milder copy of Thai food. It is not. Cambodian cooking grows from the same regional pantry - rice, river fish, coconut, lemongrass, galangal, lime, fermented fish - but it arranges those ingredients to its own taste: generally less chilli heat, less sweetness, a deep savoury base built on prahok rather than fish sauce alone, and fragrant kroeung pastes that give dishes a character you will learn to recognise within days. This guide explains the key dishes and flavours for travellers who already love eating in Thailand, so you can order in Cambodia with confidence and actually taste the difference.

A practical starting point: eat where Cambodians eat, in the order they eat. Noodle soup in the morning at a market stall. Rice with several shared dishes at lunch. Grilled and snack foods in the evening, fruit whenever it appears, strong coffee at any hour. Khmer food is not organised around a single famous dish the way visitors sometimes expect; it is a daily system, and a week of following its rhythm will teach you more than a hunt for one perfect amok. That said, the famous dishes are famous for a reason, and we will start with them.

The Dishes to Know First

Fish amok is the dish Cambodia offers first-timers, and it earns the role. Freshwater fish is coated in a coconut-rich curry built on kroeung paste, often with a leafy green folded through, then gently steamed - traditionally in a banana leaf cup - until it sets into something closer to a delicate mousse than a saucy Thai curry. The flavour is aromatic and rounded rather than fiery, with lemongrass and turmeric forward and chilli present as warmth, not attack. Compared with a Thai gaeng, amok is milder, thicker and more perfumed than pungent. Eat it with plain rice, order it at a proper Khmer restaurant rather than a generic tourist menu for your first time, and you will understand immediately that this kitchen is doing its own thing.

Beef lok lak is the other name every visitor learns. Cubes of beef are stir-fried and served - classically on a bed of salad leaves, tomato and onion, with a fried egg on top in many places - alongside a dipping sauce of lime juice and black pepper that does much of the dish's work. The pepper matters: Cambodia, and especially the Kampot region, is renowned for pepper, and lok lak is one of its best showcases. Thailand-based travellers will think of a peppery beef stir-fry, but the presentation as a salad-plate with a sharp, peppery dip is distinctly Khmer-French in feel - a reminder that Cambodian food also carries a French colonial layer, visible in its bread, its coffee culture and dishes like this one.

Kuy teav is breakfast. This clear noodle soup - rice noodles in a pork-based broth, with sliced pork, minced pork, offal for those who want it, bean sprouts, herbs and garlic oil - is the bowl Phnom Penh starts its day with. If you know Thai kuay teow, the format is familiar but the bowl is different: less sweet, rarely as chilli-hot, with the diner seasoning at the table from a familiar caddy of sugar, chilli, fish sauce and pickled garlic. Order it at a busy morning stall, add herbs generously, and drink the iced tea or strong coffee that arrives alongside. A traveller who has eaten kuy teav at a market stall at seven in the morning has had a more authentically Cambodian food experience than one who has eaten three famous dishes at a hotel.

Around those three, keep an eye out for the wider repertoire. Samlor - soups and soupy curries - come in many forms, including sour soups brightened with tamarind or lime and herbal broths that will remind Thai-food lovers of tom-style soups while tasting distinctly themselves. Grilled river fish, eaten with rice and a herb-heavy dip, is everyday food near the Mekong and Tonle Sap. Bai sach chrouk - grilled pork over broken rice, with pickled vegetables - is the other great Cambodian breakfast, simple and deeply satisfying. Nom banh chok, fresh rice noodles with a fish-based gravy and a tumble of raw herbs and vegetables, is the dish many Cambodians name as their own favourite, and its herb basket makes Thai khanom jeen the obvious, imperfect comparison: similar idea, different gravy, different balance.

Prahok: The Flavour Underneath

No ingredient explains Khmer food better than prahok, the fermented fish paste made from the catch of the Tonle Sap and Cambodia's rivers. Where Thai cooking uses fish sauce as a primary salty seasoning - clean, liquid, precise - Cambodian cooking leans on prahok's deeper, funkier, more complex savouriness, used in pastes, dips and soups, sometimes fried, sometimes blended with lemongrass and herbs into prahok ktiss, a rich dip eaten with raw vegetables. First encounters can be intense for newcomers; prahok does not apologise for itself. But it is the foundation note of the cuisine, and travellers who give it a few tries, in well-made dishes rather than as a dare, usually come to appreciate the depth it gives food that no other seasoning replicates.

The comparison with Thailand is instructive here, because Thailand has its own fermented fish traditions - pla ra in Isan cooking is a close cousin in spirit - and Scott's home province of Surin, in southern Isan near the Cambodian border, sits in the cultural zone where those flavours overlap. Food, like language, ignores the modern border in the border provinces. Elsewhere, though, the distinction holds as a useful rule of thumb: Thai food builds saltiness primarily with fish sauce and lifts dishes with chilli, lime and sugar in a bright balance; Khmer food builds depth with prahok and kroeung and keeps the bright notes quieter. Neither is better. They are two answers to the same abundant rivers and rice fields.

Kroeung: The Paste at the Heart of It

If prahok is the foundation, kroeung is the architecture. Kroeung refers to the family of freshly pounded herb pastes - lemongrass, galangal, turmeric, garlic, shallots and kaffir lime zest in varying proportions, with dried chillies in the red versions - that season curries, stir-fries, soups and amok. Thai curry paste is the obvious comparison, and the ingredient lists overlap heavily, but the emphasis differs: kroeung tends to foreground lemongrass and turmeric aromatics over chilli heat, which is why so many Khmer dishes taste fragrant and golden rather than fiery and red. In markets across Cambodia you will see kroeung sold freshly made, in mounds, by vendors whose customers buy it by the spoonful for that day's cooking - a sign of a living, everyday cuisine, not a preserved one.

For the home cook travelling slowly, markets are a classroom. Spend a morning in a Cambodian market with no shopping list at all, just watching: the herb piles, the fish from the Tonle Sap laid out by size, the prahok and fermented products in their own pungent corner, the kroeung vendors, the pepper, the palm sugar, the fruit you know from Thailand - mango, mangosteen, rambutan, durian in season - alongside everything arranged for a Khmer kitchen. Markets in Phnom Penh, Siem Reap and Kampot all reward this kind of slow looking, and a guided market visit, where offered by a reputable cookery class, is one of the best food investments a long-staying traveller can make. Cookery classes in Siem Reap and Phnom Penh commonly include a market tour plus amok and a soup or salad, and you will taste your own kroeung-based cooking with new respect for the vendors who pound it daily.

Heat, Pepper and the French Layer

Chilli in Cambodia is a seasoning you add, more than a foundation you endure. This surprises travellers arriving from Thailand, where heat is often built into the dish before it reaches you. In a Khmer kitchen, the base dish is commonly mild-to-warm, with fresh chillies, chilli sauces and pepper on the table or in a dipping sauce, so each diner sets their own level. People who love Thai food but struggle with its hottest dishes often find Khmer food a relief; people who chase heat will find it, but they will add it themselves. Kampot pepper deserves its reputation in this system: used fresh as green peppercorns in stir-fries and sauces, or dried in the lok lak dip, it provides a fragrant, building warmth that is Cambodia's signature form of spice. If you buy one food souvenir, pepper from a reputable source in Kampot itself is the one travellers consistently use up and regret not buying more of.

The French layer is the other difference a Thailand-based eater notices quickly. Baguettes are everyday food in Cambodia in a way they are not in Thailand - sold from carts and bakeries, filled as sandwiches with pate, meats and pickles in a combination that echoes the Vietnamese banh mi while remaining its own Cambodian street staple, the num pang. Coffee culture, too, carries the French influence, adapted to local taste: strong coffee, often served iced with condensed milk, in cafes that range from plastic-stool street corners to elegant old Phnom Penh interiors. Pate appears, butter appears, and certain restaurant dishes carry French technique under Khmer seasoning. Rather than feeling imported, this layer has been absorbed over generations into what Cambodian food simply is - much as Thai food absorbed Chinese techniques so completely that they now read as Thai.

Markets, Street Food and Eating Safely

Street and market eating in Cambodia follows the same common-sense rules as in Thailand, and travellers who already eat confidently in Thai markets need no new system - just the discipline to keep using the one they have. Choose stalls that are busy, ideally with a crowd of local customers, because high turnover means fresh ingredients and a reputation being protected. Prefer food cooked to order and served hot over food that has sat; soups, grilled items and stir-fries at active stalls are the natural choices. Drink water and ice from sources you trust - factory ice is the regional norm in established eateries - and wash or sanitise hands before eating, as you would at home in Isan.

Ordering without Khmer is manageable. Menus in tourist-facing places are often bilingual, market ordering runs on pointing and smiling everywhere in the region, and learning the names in this article - amok, lok lak, kuy teav, nom banh chok, bai sach chrouk - covers a remarkable share of what you will actually want to eat. Add the words for rice, water, coffee and thank you, and you can feed yourself well in any market in the country. Prices in markets and local eateries are generally reasonable by regional standards; carry small notes in both dollars and riel, expect small change partly in riel, and bargain in markets gently and only where it is clearly the custom, keeping the amounts in perspective.

One adjustment for Thailand-based travellers: meal timing. Breakfast is early and taken seriously, lunch is the other substantial meal, and in smaller towns kitchens close earlier in the evening than a Bangkok or Patong regular might expect. Plan dinner earlier outside Phnom Penh and central Siem Reap, and let the early schedule carry you - a market breakfast at seven and dinner by seven is the rhythm the country itself keeps, and eating on local time is half of eating local food properly.

A Week of Eating Your Way Through

To close, here is how a food-focused week might actually unfold. Day one in Phnom Penh: kuy teav at a market stall, a long look around the market afterwards, amok for dinner at a Khmer restaurant. Day two: bai sach chrouk for breakfast, a cookery class or market tour if you have booked one, grilled fish and prahok ktiss with vegetables for those ready for the deep end. In Siem Reap: nom banh chok from a morning vendor, samlor at a family restaurant for lunch, lok lak with proper Kampot pepper in the evening - and street snacks and fruit in between, because a slow stay should always leave room for whatever the stall on the corner is selling that day. On the coast in Kampot and Kep: seafood first, especially Kep's crab prepared simply, pepper crab if you see it, and a bag of Kampot pepper bought from a source you trust to take home.

None of this requires expertise, a tour or a large budget. It requires appetite, mornings, and the willingness to let a neighbouring cuisine be itself rather than a variation on the one you already love. Thailand-based travellers are, in fact, the ideal audience for Khmer food: close enough to recognise the foundations, far enough to be surprised by what Cambodia builds on them. Eat the soup at seven in the morning, taste the prahok without flinching, add your own chilli - and Cambodia will feed you very well indeed.
