Thai food is one of the highlights of visiting Koh Samui, but many visitors end up ordering the same familiar dishes throughout their holiday. While there's nothing wrong with a Pad Thai or Green Curry, Thailand's cuisine is far broader than the handful of dishes that appear on restaurant menus around the world.
Whether you're eating at a beachfront restaurant, a local family-run café or one of the island's night markets, you'll find plenty of opportunities to try authentic Thai cooking. Knowing what to order makes a huge difference, especially when menus don't always explain what each dish actually is.
These are seven Thai dishes worth ordering while you're on Koh Samui, along with what to expect before they arrive at your table.
1. Pad Krapow (Holy Basil Stir Fry)
If there's one dish that locals eat as often as visitors order Pad Thai, it's Pad Krapow. Made with minced pork, chicken or beef, it's stir-fried with garlic, fresh chillies and holy basil before being served over steamed jasmine rice. A crispy fried egg on top is the finishing touch and well worth adding.
Don't confuse holy basil with the sweet basil used in many Western Thai recipes. Holy basil has a peppery, slightly spicy flavour that gives the dish its distinctive character. It's fast, inexpensive and found almost everywhere on the island, from roadside cafés to restaurant menus.
Be aware that local versions can be surprisingly spicy. If you prefer something milder, simply ask for fewer chillies.
2. Tom Yum Goong
Few dishes capture the balance of Thai flavours better than Tom Yum Goong. This hot and sour soup combines prawns with lemongrass, galangal, kaffir lime leaves, mushrooms and fresh chillies to create a broth that's aromatic rather than heavy.
Some restaurants serve a clear broth, while others add evaporated milk or a spoonful of chilli paste to create a richer version. Neither is more authentic than the other, so it's worth trying both during your stay.
Despite the name, Tom Yum can also be prepared with seafood, chicken or fish if prawns aren't your preference.
3. Massaman Curry
Unlike Thailand's fiery red and green curries, Massaman Curry is gentle, rich and comforting. Influenced by Persian and Malay cooking, it combines slow-cooked beef or chicken with potatoes, onions, roasted peanuts and warming spices such as cinnamon and cardamom.
It's one of the easiest Thai curries for newcomers to enjoy because the spice level is usually much lower than many other traditional dishes. The flavour comes from the spice blend rather than overwhelming heat.
If you're introducing someone to Thai food for the first time, Massaman Curry is often a safe place to start.
4. Som Tam (Green Papaya Salad)
Som Tam looks innocent enough until the first mouthful. Made from shredded green papaya, tomatoes, long beans, peanuts, dried shrimp, fish sauce, lime juice and fresh chillies, it's one of Thailand's most refreshing dishes.
The combination of sweet, sour, salty and spicy flavours is what makes it so popular, particularly on hot afternoons. It's commonly ordered alongside grilled chicken or sticky rice rather than eaten on its own.
Heat levels vary dramatically depending on who's preparing it. If you don't enjoy very spicy food, asking for one or two chillies instead of the traditional handful can make all the difference.
5. Pad Thai
It may be Thailand's most recognised dish internationally, but that's no reason to skip it. A well-made Pad Thai deserves its reputation.
Rice noodles are stir-fried with egg, tofu, bean sprouts and your choice of prawns, chicken or pork before being finished with crushed peanuts, fresh lime and chilli flakes served on the side. The balance of tamarind, fish sauce and palm sugar is what separates a great Pad Thai from an average one.
Every restaurant seems to have its own version, making it one of the easiest dishes to compare during your time on Koh Samui.
6. Khao Soi
Khao Soi originates from Northern Thailand rather than the islands, but it's becoming increasingly common in Koh Samui's restaurants, particularly those specialising in regional Thai cuisine.
The dish combines egg noodles with a creamy coconut curry broth, usually topped with chicken or beef, crispy fried noodles, pickled mustard greens, shallots and lime.
It's richer than many noodle dishes and makes an excellent choice if you're looking to try something beyond the standard tourist favourites.
7. Mango Sticky Rice
No introduction to Thai food is complete without dessert. Mango Sticky Rice combines sweet ripe mango with glutinous rice that's been cooked in coconut milk before being finished with a drizzle of coconut cream and toasted mung beans or sesame seeds.
The quality depends almost entirely on the mango. During mango season you'll understand why this simple dessert has become so well known, while outside the season the fruit can vary considerably.
If you see it freshly prepared at one of Koh Samui's markets, it's well worth trying.
A Few Tips Before You Order
One mistake many visitors make is asking for "Thai spicy" because they assume they'll receive the authentic version. Thai spice levels can be significantly hotter than most people expect, and many restaurants automatically reduce the heat for visitors for good reason.
If you're unsure, start with mild or medium and work your way up. You can always add extra chilli, but it's much harder to rescue a meal that's become too spicy to enjoy.
It's also worth exploring beyond the busiest tourist areas. Small family-run restaurants often serve some of the island's most memorable meals, even if the décor is basic and the menu has seen better days.
