Cambodian beef lok lak is a quick skillet dish of savory, peppery beef served with rice, crisp vegetables, and a tangy lime-and-pepper dipping sauce. This version uses familiar pantry sauces and garlic; fresh lemongrass and Kampot pepper are optional touches, since Cambodian households and recipes vary in their seasonings.
Ingredients
- 1½ cups (285 g) long-grain white rice
- 2¼ cups (530 ml) water, or the amount specified on your rice package
- 1½ lb (680 g) boneless beef sirloin, tenderloin, or flank steak, cut across the grain into strips about ½ inch (1.3 cm) thick
- 2 tbsp (30 ml) soy sauce
- 1 tbsp (15 ml) oyster sauce
- 1 tbsp (15 ml) fish sauce
- 1 tsp (4 g) granulated sugar
- 3 garlic cloves (about 9 g), finely minced
- 1 tsp (2 g) freshly cracked black pepper, preferably Kampot pepper if available
- 1 tbsp (15 ml) neutral cooking oil, such as canola or sunflower oil
- 2 tbsp (30 ml) fresh lime juice, for the dipping sauce
- 1 tsp (2 g) freshly cracked black pepper, for the dipping sauce
- ¼ tsp (1.5 g) fine salt, for the dipping sauce
- 1 tbsp (15 ml) water, for the dipping sauce
- 1 small head (about 150 g) butter lettuce or green-leaf lettuce, leaves separated and washed
- 2 medium tomatoes (about 300 g), cut into wedges
- ½ small red onion (about 55 g), thinly sliced
- 1 small cucumber (about 200 g), sliced, optional
- 1 lime (about 60 g), cut into wedges, for serving
Instructions
- Prepare the rice. Rinse the rice in a fine-mesh strainer until the water runs mostly clear, then drain. Combine it with the measured water in a saucepan and bring to a boil. Cover, turn the heat to low, and cook according to the package directions, usually about 15 minutes. Turn off the heat and leave it covered for 5 minutes, then fluff with a fork. If your rice package calls for a different water ratio or timing, follow that guidance.
- Mix and chill the beef. In a medium bowl, stir together the soy sauce, oyster sauce, fish sauce, sugar, minced garlic, and 1 teaspoon cracked pepper until the sugar dissolves. Add the beef and turn to coat. Cover and refrigerate for 20 minutes while you prepare the vegetables and dipping sauce. Avoid leaving raw beef at room temperature to marinate.
- Make the lime-pepper sauce. Stir the lime juice, 1 teaspoon pepper, salt, and water together in a small serving bowl. Taste it: it should be sharply sour and peppery, with enough salt to balance the lime. Add a little more water if you prefer a milder dip. Set the lettuce, tomatoes, onion, cucumber if using, and lime wedges on a platter.
- Heat the pan. When the rice is nearly ready, heat a large, heavy skillet over medium-high heat until hot. Lift the beef from the marinade, letting excess liquid drip back into the bowl. Discard the used marinade; do not serve it as a sauce. Patting the strips lightly with a paper towel helps them brown instead of steam.
- Sear in batches. Add the oil to the hot skillet and swirl to coat. Arrange enough beef in a single layer to leave a little space between pieces. Sear for about 2 minutes, turn, and cook for another 1–2 minutes, adjusting for the thickness of the strips. Transfer the first batch to a clean plate and repeat with the remaining beef. Crowding the skillet cools it and can make the meat release liquid, so use three batches if needed.
- Check doneness and rest. Use a food thermometer to check the thickest beef pieces. USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of beef. Transfer the cooked beef to a clean plate and let it rest for 3 minutes. If a piece has not reached the safe minimum, return it to the hot pan and check again.
- Serve. Spoon rice into bowls or onto plates. Add the beef and arrange the lettuce, tomato, onion, and cucumber alongside. Serve the lime-pepper sauce and lime wedges at the table so each person can dip or dress the beef to taste.
Tips
- Cut across the grain. Look for the long muscle fibers in the steak and slice across them. This shortens the fibers and makes each bite easier to chew. Keep the strips a similar thickness so they cook at roughly the same rate.
- Choose a suitable cut. Sirloin and tenderloin cook quickly and stay tender, while flank steak has a more pronounced beefy texture. If using flank, slice it particularly carefully across the grain. Very lean, thin-cut steak can dry out if left in the pan too long.
- Swap the pepper thoughtfully. Kampot pepper is a Cambodian-grown pepper prized for its aromatic, bold character, but it can be hard to find. Freshly cracked black pepper is a practical substitute; use the same quantity, knowing the flavor will be less distinctive. Pre-ground pepper works in a pinch but tastes flatter.
- Keep the pan hot and uncrowded. If the beef is steaming or turning gray, cook smaller batches and let the skillet reheat between them. A little browned color adds savory flavor, but avoid cooking the strips long after they reach the safe temperature.
Serving Suggestions
Serve lok lak hot over steamed white rice, with the vegetables arranged beside it rather than stirred into the beef. The crisp lettuce, juicy tomatoes, and sharp onion provide contrast to the salty, browned meat, while the lime-pepper sauce cuts through its richness. Diners can spoon the sauce over a few bites or dip each piece of beef immediately before eating. A bowl of extra lime wedges makes it easy to adjust the acidity at the table.
For a more filling meal, add a fried egg on top, as some versions do, or serve a simple vegetable soup alongside. The egg is an optional addition, not part of the timing or ingredients above. If you include one, cook it until the white and yolk are firm or, for an egg dish prepared another way, to 160°F (71°C). Keep the rice and beef warm while setting out the cold vegetables so they stay crisp.
Variations
Add lemongrass: For a fragrant variation, finely mince 1 tablespoon (about 6 g) tender inner lemongrass and mix it into the beef marinade. Remove any tough outer layers first. Lemongrass is not required for this pepper-forward version, and it gives the meat a brighter citrus-herbal note.
Adjust the sauces: Fish sauce contributes salty depth, while oyster sauce adds sweetness and body. If you need to avoid fish sauce, replace it with an equal amount of soy sauce; the result will be less pungent and slightly less rounded. For a vegetarian variation, use thick strips of firm tofu and vegetarian mushroom stir-fry sauce in place of the beef and oyster sauce. Brown the tofu in batches and season to taste; the texture and cooking time will differ from the beef version.
Use a different pepper dip: Increase the cracked pepper for a more assertive sauce, or leave it at the stated amount and add another teaspoon of lime juice for a sharper dip. A small pinch of sugar can soften the acidity, but keep the sauce tart enough to balance the savory beef. These adjustments are easy to make at the table without changing the marinade.
Storage and Reheating
Refrigerate cooked beef and rice within 2 hours of cooking, ideally in separate shallow, airtight containers so they cool promptly. They keep for 3–4 days in a refrigerator at 40°F (4°C) or colder. Store the washed vegetables and lime-pepper sauce separately; the vegetables are best eaten fresh, and the sauce is brightest on the day it is made. Discard any sauce that has been in contact with raw beef or used for dipping after serving.
Reheat only the amount you plan to eat. Warm the beef in a covered skillet over medium-low heat with a teaspoon or two of water, stirring just until hot, or microwave it in short bursts, stirring between intervals. Reheat leftovers to 165°F (74°C), checking with a food thermometer. Rice can be reheated with a splash of water, covered, until steaming hot and at the same temperature. Do not reheat the same portion repeatedly. For longer storage, freeze the beef and rice in airtight containers for up to 2 months for best quality, then thaw in the refrigerator and reheat to 165°F (74°C).
Frequently Asked Questions
Is Cambodian beef lok lak spicy? It is usually peppery rather than chile-hot. This recipe uses black pepper in the marinade and dipping sauce but no chile. Add sliced fresh chile or a pinch of chile flakes at the table if you want heat; keeping it separate lets everyone adjust their own serving.
Can I make the beef ahead? You can mix the marinade and slice the beef a few hours ahead, then keep them covered separately in the refrigerator. For best texture, coat the beef and marinate it for about 20 minutes just before cooking; a much longer soak can make the surface overly salty. You can also wash and slice the vegetables ahead, storing them chilled in a separate container.
What can I use instead of Kampot pepper? Freshly cracked black pepper is the easiest substitute and is what this recipe is designed to use. Kampot pepper has its own aromatic character, but it is not essential to the method. Use an equal amount and taste the dipping sauce before serving, since pepper varieties can vary in pungency.
Can I cook this without a wok? Yes. A large, heavy skillet works well and is often easier to manage on a home stove. Heat it thoroughly and sear the beef in batches rather than trying to cook everything at once. A wok is useful, but it is not necessary for the browned, quick-cooked result.
Can I use a different cut of beef? Sirloin, tenderloin, and flank steak are all suitable when sliced across the grain. Choose a relatively tender cut because the strips cook quickly and are not braised. If using a thicker or tougher cut, do not simply leave it in the pan for a long time; cut it thinly across the grain and check the temperature and texture as it cooks.
