Cambodian curry paste, often referred to as kroeung, is the aromatic base used in many Khmer recipes. The three principal varieties—red, yellow and green—use different spice and herb combinations and are applied to distinct types of soups, stews and grilled dishes.
What Cambodian curry paste is and its culinary background
Kroeung is the Khmer term for a blended spice-and-herb paste that provides the core flavor for much of Cambodia's cooked food. The mixture typically combines fresh aromatics like lemongrass, galangal and kaffir lime with dried spices and, in many preparations, a touch of shrimp paste for umami.
The pastes are not a single recipe but a family of closely related preparations. Regional and household differences mean each kroeung can vary in proportion and addition of ingredients, yet the function is the same: to season proteins, vegetables and broths before cooking.
Key features and the main types of kroeung
There are three widely recognised kroeung profiles. Red kroeung uses dried red chillies and warmer spices; yellow kroeung highlights fresh or dried turmeric for its golden color; green kroeung emphasises fresh green herbs and chillies for a perfumed, herbaceous character. Each produces a distinct color and aroma when cooked.
Common components across the three include lemongrass, galangal, shallots, garlic and kaffir lime zest. Coconut milk is often added to Cambodian curry dishes rather than to the paste itself, supplying a creamy balance to the spice blend when the paste is cooked into a sauce or broth.
- Red kroeung: typically spicy and robust; often paired with slow-cooked meats and thicker curries.
- Yellow kroeung: dominated by turmeric and citrusy notes; popular for skewers and some snack-style sauces.
- Green kroeung: fresher, brighter and more herb-forward; used for lighter soups and quick pan-fried dishes.
Practical tips for buying, storing and making kroeung
If you plan to cook with kroeung, note that commercially prepared pastes vary in concentration and saltiness. Visitors report that market-made pastes are usually fresher and more aromatic than supermarket jars, but they can also be stronger, so adjust quantities to taste.
Home cooks can build a paste in a food processor or traditional mortar and pestle. Softening dried chillies before blending and adding a small amount of neutral oil helps the blades or pestle create a smoother texture. Leftover paste keeps best refrigerated in an airtight container for several days or frozen in portions for longer storage.
- Soak dried chillies in hot water for 10–20 minutes to soften before blending.
- Reserve a tablespoon of shrimp paste (kapi) to add depth; use sparingly if you prefer milder umami.
- Portion and freeze to preserve freshness and make future meal prep quicker.
Cultural role and how kroeung fits into Khmer food traditions
Kroeung is more than a seasoning; it represents a cooking technique passed down through families and marketplaces. Many dishes start by frying the paste briefly to release oils and mellow raw edge before adding liquids, proteins or vegetables.
Street food and home-style plates both rely on kroeung, but they use it in different ways. Street vendors might mix a paste into quick grill marinades or noodle soups, while household cooks often use it as a base for longer-simmered curries and stews.
- Frying the paste in oil or coconut cream softens its sharpness and builds depth.
- Local recipes vary; visitors typically notice differences between urban and provincial styles.
Who will enjoy cooking with kroeung and who should be cautious
Home cooks who like to experiment with aromatics and spice blends will find kroeung rewarding: it allows control over heat level, herb freshness and salty umami. It also adapts well to proteins, vegetables or plant-based alternatives when coconut milk or stock is added.
People sensitive to hot chillies or strong fermented seafood flavours should approach kroeung with care. Many recipes include shrimp paste, which gives a pronounced savoury note; that can be omitted or reduced, but the flavour profile will shift noticeably.
- Good for: cooks who enjoy layered flavours, makers of grilled meats, and those learning Southeast Asian spice techniques.
- Be cautious if: you avoid shrimp-based products or have a low tolerance for chilli heat.
Comparisons and alternatives to Cambodian curry paste
Kroeung shares some similarities with other Southeast Asian pastes—Thai curry pastes and Malaysian rempah, for example—yet it retains distinct ingredient choices and proportions. Compared with Thai pastes, kroeung often leans more on lemongrass and galangal with a less uniform use of fresh chillies.
If you cannot find kroeung, you can sometimes adapt nearby pastes by adding missing aromatics (for example, boosting lemongrass and kaffir lime in a store-bought Thai paste). However, that substitution will not reproduce the exact Khmer profile.
| Aspect | Red kroeung | Yellow kroeung | Green kroeung |
|---|---|---|---|
| Typical dominant ingredients | dried red chillies, galangal, lemongrass | turmeric, lemongrass, kaffir lime zest | green chilli, cilantro, basil, lemongrass |
| Common colour | deep red | golden yellow | green |
| Heat level (typical) | medium to hot | mild to medium | mild to medium |
| Best used for | richer curries, marinades, stews | skewers, snack sauces, some curries | soups, stir-fries, light sauces |
Recipes and dishes that feature kroeung
Several well-known Khmer dishes rely on one of the kroeung varieties. Sach Ko Ang, or grilled beef skewers, commonly uses yellow kroeung to produce a golden coating on the meat. Cambodian chicken red curry—often referred to by locals with a name meaning chicken curry—makes use of red kroeung combined with coconut milk for a richer, saucier result.
Noodle soups are another important context for kroeung. Samla Num Banh Chok, a popular rice-noodle dish served with a green herb-scented broth, typically features a green kroeung influence on its soup base.

Street vendors often produce skewers and quick snacks close to cycling routes and temple areas; visitors using two wheels to explore heritage zones will find many stalls serving kroeung-seasoned street food.

Frequently Asked Questions
What is kroeung and how does it differ from Thai curry paste?
Kroeung is a Khmer blended paste built from aromatics like lemongrass, galangal and kaffir lime, often combined with spices and sometimes shrimp paste. While similar in purpose to Thai curry pastes, kroeung recipes place distinct emphasis on certain herbs and may use different chilli types and proportions, creating a unique Khmer flavour profile.
Can I make kroeung without shrimp paste?
Yes. Shrimp paste adds salty, fermented depth to many traditional recipes, but omitting it is common for those with allergies or dietary restrictions. If you remove it, consider increasing other umami elements (such as roasted spices or a small amount of soy) to compensate, keeping in mind the result will not exactly match the original taste.
How should kroeung be stored and for how long?
Freshly made kroeung will keep refrigerated in an airtight container for several days. For longer preservation, freeze small portions in ice-cube trays or sealed bags; thaw only what you need to retain aromatic quality. Commercial jars may last longer but check labels and vendors’ advice for specific guidance.
Which kroeung should I use for noodle soups?
Green kroeung is most commonly associated with herbal, broth-based noodle dishes, as its fresh herbs and green chillies complement lighter broths. Red kroeung can be used for richer, coconut-based soups when a more robust flavour is desired.
Are kroeung pastes spicy?
Spice level varies by recipe and maker. Red kroeung tends to be the hottest of the three, while yellow and green versions are often milder. When buying in markets, vendors can usually indicate heat level; when cooking, adjust chilli amounts to your preferred tolerance.
