There’s nothing quite like the aroma of lemongrass-marinated beef sizzling over hot coals. This Cambodian classic brings bold, citrusy flavors to your grill with a foolproof technique I’ve perfected through years of competition cooking.
The marinade combines fresh lemongrass with garlic, fish sauce, and a touch of sugar to create a balance of sweet, salty, and umami. I always source my herbs from local farmers markets for the most aromatic results.
After marinating for at least 4 hours, the beef skewers cook quickly over high heat, developing a beautiful char while staying tender inside. The citrus notes from the lemongrass shine through with every bite.
Serve these skewers with rice or fresh herbs for a complete meal that captures the essence of Cambodian street food. The flavors are complex yet approachable, perfect for adventurous home cooks.

The lemongrass is non-negotiable here. Farmers markets or Asian grocers have the freshest (look for firm, pale green stalks). I’ve tried dried lemongrass paste in a pinch—it works but lacks that bright, citrusy punch. For the beef, sirloin is ideal (tender, flavorful), but flank steak works too. Costco has great sirloin at a good price if you’re feeding a crowd.
No fresh lemongrass? Lemongrass paste at half the amount (sold in tubes near the fresh herbs). Fish sauce is key—Red Boat or Three Crabs are my go-tos. Vegetarian? Coconut aminos gets you close. Short on marinating time? Even 1 hour makes a difference (but 4+ is ideal). The brown sugar can be swapped for coconut sugar if you prefer.
Marinated beef keeps in the fridge for 1-2 days—great for prepping ahead. Leftovers? Slice thin and toss into stir-fries or rice bowls. The skewers themselves are best hot off the grill, but they’ll keep 3-4 days refrigerated. Reheat quickly on the grill or in a hot pan to keep them tender.

Step-by-Step Instructions for Cambodian Grilled Lemongrass Beef Skewers
Here’s how I create these skewers with maximum flavor and that perfect char.
Step 1: Prepare the Lemongrass Beef Marinade
In a large bowl, combine the 3 tbsp fish sauce, 2 tbsp brown sugar, 2 tbsp soy sauce, 2 tbsp lime juice, 2 tbsp vegetable oil, 1 tsp black pepper, and 1 tsp salt. Whisk until the brown sugar dissolves completely—this ensures even flavor distribution.
Add the minced 3 whole fresh lemongrass stalks and 6 cloves garlic cloves to the bowl. Stir well to combine. The aromatics should release their fragrance immediately, signaling the marinade is ready for the 1.5 lb beef sirloin.
Step 2: Marinate the Beef Sirloin Cubes
Add the 1.5 lb beef sirloin (cut into 1-inch cubes) to the marinade. Use your hands to gently massage the marinade into every piece, ensuring full coverage. Cover the bowl with plastic wrap and refrigerate for at least 4 hours, or ideally overnight.
This marinating time allows the bold flavors of the fish sauce, lime juice, and garlic to penetrate the beef deeply. You’ll notice the meat darkens slightly as it soaks up the marinade—a sign the flavors are working their magic.
Step 3: Skewer and Grill to Perfection
Thread the marinated beef cubes onto the 12 pieces bamboo skewers (soaked in water for 30 minutes to prevent burning). Leave a little space between each piece so the heat can circulate and cook the beef evenly.
Grill the skewers over medium-high heat for 3-4 minutes per side until the beef is charred at the edges and reaches an internal temperature of 145°F for medium-rare. The sugar in the marinade will caramelize, creating a beautiful, slightly sticky glaze.
Step 4: Serve with Fresh Garnishes and Jasmine Rice
Transfer the skewers to a platter and let them rest for 5 minutes. This allows the juices to redistribute, keeping the beef tender and flavorful. While they rest, thinly slice the 1 whole red onion and chop the 0.5 cup fresh cilantro.
Serve the skewers hot, garnished with the sliced red onion and chopped fresh cilantro. Pair with 2 cups jasmine rice, cooked according to package instructions. The combination of the smoky beef, fresh herbs, and fragrant rice is what makes this dish unforgettable.
Pro Tips For Making Cambodian Grilled Lemongrass Beef Skewers
- Soak the Skewers: I learned this the hard way—soak your wooden skewers in water for at least 30 minutes before threading the beef. Otherwise, they’ll char before the meat even cooks through.
- Pound the Lemongrass: Sounds weird, but it works: lightly smash the lemongrass stalks with the side of your knife before mincing. It releases way more aromatic oils into the marinade.
- Slice Against the Grain: Cut the sirloin into thin strips against the grain for tender skewers. After burning three batches of chewy beef, I finally figured out this was the culprit.
- Char Quick, Rest Long: Grill over high heat for 2-3 minutes per side for a good sear, then let the skewers rest under foil for 5 minutes. The juices redistribute—my grandmother swore by this, and she was right.

Frequently Asked Questions
How do I prepare lemongrass for the marinade?
Remove the tough outer layers and trim the root end. Use only the tender 4-6 inches of the stalk, then mince finely. For best results, use fresh lemongrass—dried paste lacks the bright citrus flavor.
Can I use a different cut of beef?
Yes! While sirloin is ideal, flank steak or ribeye work well too. Avoid lean cuts like tenderloin—they lack the fat needed for juicy skewers. Always cut against the grain for tenderness.
How do I know when the skewers are done?
Grill until the beef reaches an internal temperature of 145°F for medium-rare, about 3-4 minutes per side. Look for charred edges and a slight caramelized glaze from the marinade.
Can I make these skewers ahead of time?
Marinate the beef for up to 2 days in the fridge. Thread onto skewers just before grilling to prevent drying. Leftovers keep 3-4 days and reheat well on the grill or in a pan.
