Authentic Thai Beef Larb Recipe

Beef Larb (ลาบเนื้อ) is a bold, herb-forward Thai beef salad from Northeastern Thailand, known for its bright lime, fish sauce, toasted rice powder, chilies, and fresh herbs. This version uses grilled, thinly sliced steak for a heartier, meat-forward take while staying true to classic Isaan flavors.

For the most traditional Isaan-style version made with ground pork, see my Laab Moo (Isaan-Style Thai Pork Larb).

In Isaan cooking, beef larb is made in many ways depending on the household and personal preference. While some versions use lightly parboiled or finely chopped beef, this recipe uses grilled, sliced steak for deeper flavor and texture.

What Is Beef Larb?

Larb (also spelled laab or laap) is a traditional Thai meat salad seasoned with lime juice, fish sauce, toasted rice powder (khao khua), chilies, and fresh herbs. It’s one of the most popular dishes in Isaan cuisine.

Why This Version Uses Grilled, Thinly Sliced Beef

Growing up in Isaan, I ate beef larb prepared in many different ways. This version is inspired by my nephew Youn, who often makes larb using grilled, sliced beef instead of minced or parboiled meat. That method always stood out to me.

This recipe reflects how larb can be cooked and shared at home in Isaan. It’s still very much larb, just bold, meaty, and full of flavor, not a single fixed or “official” version.

Key Ingredients for Beef Larb

• Grilling beef. This is an important ingredient for this recipe. Choose thick-cut beef with some fat in it for this recipe. I used top London broil and ribeye. 
• Fish sauce. I used Squid brand fish sauce. Adjust yours as needed, as each fish sauce has a different level of saltiness. Soy sauce is not recommended.
• Fresh Lime juice. Lemon juice can be used as a substitute, but lime juice is best as it adds a sharp flavor to the salty flavor of the salad. 
• Shallot. Red onions are fine as a substitute.
• Green onions. Use both the white and green parts of the green onions. 
• Cilantro. Cilantro is optional but common. Often times, culantro is used instead, but hard to find in the West.
• Mint leaves. An essential ingredient that adds a light and refreshing flavor to many Thai recipes. 
• Sugar. Use white, brown, or palm sugar to help balance out the salty and sour spicy dressing.
• Fresh chili pepper. Use as many as needed for your spice level tolerance. Find these at most Asian grocery stores or your local farmer's markets. 
• Dried chili flakes. For added spice and nutty flavor from the toasted chili flakes.
• Oil. Just a tiny amount if pan frying the meat. No need for oil if grilling.
• Toasted Rice Powder (Khao Khua): An essential ingredient that adds nutty flavor and a lightly crunchy texture.
• MSG. Optional and traditional in many Isaan kitchens. Used in very small amounts (½ ts) to enhance savory balance. MSG in Thai Cooking here.
• Pla ra. Also optional but will add an umami isaan flavor to your laab. (1-2 teaspoons).

How to Make Larb

Step 1: Make Khao Khua. Toast uncooked rice, preferably Thai glutinous rice, in a small dry pan over medium heat. Stir often until the grains turn lightly golden and fragrant. Transfer to a spice grinder or use a small mortar and pestle, then grind into a coarse powder. Set aside.

Step 2: Lightly marinate the beef. In a large bowl, mix fish sauce, lime juice, and 1 teaspoon of sugar. Whisk until the sugar dissolves. Add the beef and toss gently so the marinade coats all sides. This is a quick, light marinade, not meant to sit for long.

Step 3: Cook the beef. Heat a sauté pan over medium-high heat and add just a small drizzle of oil. If grilling, no oil is needed. Add the marinated beef and cook for a couple of minutes per side, depending on how rare or cooked you prefer it.
Remove from heat and let the beef rest for 8 to 10 minutes before slicing. This helps keep it juicy and tender.

Step 4: Prepare the salad base. In a large bowl, combine the herbs and remaining dressing ingredients. Toss gently to mix. The herbs are what give larb its fresh, vibrant flavor, so don’t be shy here.

Step 5: Slice and add the beef. Thinly slice the rested beef, including some of the fat, into small pieces about ⅛ to ¼ inch thick. Add the sliced beef to the bowl with the herbs and toss gently to combine.

Step 6: Finish with toasted rice powder. Sprinkle the toasted rice powder over the meat mixture. This adds a light crunch and nutty flavor that defines larb. Stir gently with a wooden spoon, then taste and adjust with more Thai chili, fish sauce, lime juice, or sugar as needed.

How Thai Larb Is Traditionally Enjoyed

Beef larb is rarely eaten on its own. It’s typically part of a larger Isaan food spread that may include: Thai sticky rice, papaya salad or Som Tam, raw vegetables like cabbage, green beans, cucumber, and herbs, grilled meats or sausages.

Kitchen Tips

• Use enough lime juice and fish sauce to fully season the beef. In traditional larb, these ingredients also help “set” the meat when it’s lightly cooked.
• Toasted rice powder (Khao Khua) can be found at Asian markets, or you can make it at home by dry-roasting raw rice until golden and grinding it into a coarse powder.
• Fresh herbs matter. Mint is essential, and green onion, shallot, and cilantro add depth. If you can find culantro, it’s a great addition. More about Thai herbs guide here.
• Adjust the heat to your liking by adding more or fewer chilies or dry ground chili flakes (Prik Bon).
• For serving, larb can be eaten with sticky rice, raw vegetables, or spooned into lettuce leaves for a lighter, wrap-style option.

Variations

• Laab Gai, chicken larb . A more lean version using ground chicken. Same bold flavors, different protein.
• Pork Larb: Use pork shoulder or pork butt for a slightly sweeter, more tender result.
• Vegetarian Larb: Try a mushroom larb using finely minced mushrooms, or a tofu-based larb for a vegan option.

Storing Leftover

Beef larb is best enjoyed fresh. If needed, leftovers can be stored in an airtight container in the refrigerator for up to 1 to 2 days. Keep in mind the herbs will soften over time.
