Step‑by‑Step Instructions for Cambodian Pepper Beef (Lok Lak)

Step 1: Prepare the Marinade
In a bowl, combine your thinly sliced sirloin steak with oyster sauce, soy sauce, sweet dark soy sauce, ground Kampot pepper, cornflour, baking soda, and grated garlic. Mix well until the beef is thoroughly coated. Set aside for at least 30 minutes to allow the flavors to meld, making your Cambodian Pepper Beef even more delicious.

Step 2: Mix the Sauces
While the beef marinates, prepare the sauces. In a small bowl, blend together the oyster sauce, soy sauce, and sugar for the stir-fry sauce; set this aside. For the dipping sauce, combine fresh lime juice, ground Kampot pepper, and sea salt in another bowl. This delicious tangy combination will elevate your Cambodian Pepper Beef experience.

Step 3: Heat the Wok
Place a large wok or skillet over high heat and add a splash of vegetable oil. Allow the oil to heat until it shimmers, indicating it’s hot enough for searing. This step is crucial for achieving that beautiful caramelization on your beef, ensuring it stays juicy and enhances the flavor of your Cambodian Pepper Beef.

Step 4: Sear the Beef
Once the oil is hot, carefully add the marinated beef in a single layer; avoid overcrowding the pan to achieve a nice sear. Cook for about 30 seconds on each side until you see a golden-brown char. This quick high-heat technique locks in moisture and flavor, making your beef tender and delicious.

Step 5: Toss in the Onions
After searing the beef, add the wedges of red onion to the wok. Stir-fry for a minute until they soften slightly, releasing their sweet fragrance. Next, pour in the stir-fry sauce mixture and toss everything together for another 30 seconds, ensuring the beef and onions are well coated in the rich sauce, intensifying the flavors of your Cambodian Pepper Beef.

Step 6: Rest & Serve
Once everything is cooked to your liking, remove the wok from the heat. Let the beef rest briefly before serving to keep it juicy. Arrange the beef and onion mixture on a bed of lettuce leaves, alongside fresh tomato slices. Serve your Cambodian Pepper Beef with steamed rice and the lime dipping sauce on the side for a complete, satisfying meal.

Expert Tips for Cambodian Pepper Beef

  • Hot Wok Essential: Ensure your wok is properly heated before adding the beef. A hot surface creates a perfect sear, locking in the moisture for your Cambodian Pepper Beef.

  • Avoid Overcrowding: Cook the beef in batches if necessary to prevent steaming. This guarantees a lovely char on each piece, ensuring tenderness and flavor.

  • Timing is Key: Monitor the cooking time for the beef closely; cooking for too long can lead to chewy meat. Aim for a quick sear for a medium-rare finish.

  • Fresh Ingredients Matter: Use fresh lime juice and high-quality Kampot pepper for the best flavor in the dipping sauce. Freshness enhances the overall taste profile of the dish.

  • Customize Your Spice Level: If you prefer a spicier kick, add more ground pepper to the marinades or sauces. Adjust according to your taste to make this Cambodian Pepper Beef your own.

Cambodian Pepper Beef (Lok Lak) Recipe FAQs

What type of beef is best for Cambodian Pepper Beef?
For the best flavor and tenderness, sirloin or striploin steak works wonderfully in Cambodian Pepper Beef (Lok Lak). If needed, flank steak can be a suitable substitute. Look for cuts that have some marbling, as this fat contributes to juiciness and flavor when cooked.

How should I store leftovers, and how long do they last?
Place leftover Cambodian Pepper Beef in an airtight container in the fridge, where it will stay fresh for up to 3 days. To keep the flavors intact, ensure the container is sealed well to prevent air exposure.

Can I freeze Cambodian Pepper Beef?
Absolutely! For freezing, first spread the cooked beef in a single layer on a baking sheet. Once frozen solid, transfer the beef to an airtight freezer bag. It can be kept in the freezer for up to 3 months. This step prevents it from clumping together, making it easier to portion later.

What if my beef turns out tough?
If your beef is tough, it may be due to overcooking. To avoid this in the future, cook the beef quickly on high heat, searing it for just 30 seconds per side. Remember, the residual heat will continue to cook the beef slightly after you remove it from the pan, so it’s best to err on the side of undercooking a bit.

Are there any dietary considerations for Cambodian Pepper Beef?
If you’re cooking for someone with dietary restrictions, consider using low-sodium soy sauce to cut back on salt. For a vegetarian option, replace beef with tofu and use mushroom-based sauces instead of oyster sauce. Always check for allergies to the specific sauces and seasonings used, especially for shellfish in oyster sauce.
