How to Make Cambodian Pepper Beef
Marinate the Beef: In a bowl, mix the sirloin cubes with cornflour, baking soda, garlic, vegetable oil, oyster sauce, soy sauce, and sweet dark soy sauce. Let it sit for about 15 minutes to soak up the flavors.
Prepare Sauces: While the beef is marinating, separately mix the sugar and lime juice for your dipping sauce, then set both sauces aside.
Cook the Beef: Heat vegetable oil in a wok or large frying pan over high heat. Sear the marinated beef cubes in batches for about 30 seconds on each side until they have a nice char and are cooked to your desired doneness.
Add Onions: Quickly toss in the red onion towards the end of the beef cooking time. Stir to combine, letting the onion soften slightly and blend with the beef.
Combine with Sauce: Pour in the stir-fry sauce and mix thoroughly. Cook for an additional 30 seconds to allow the flavors to meld together beautifully.
Serve: Lay down the lettuce on your serving plate, layer with slices of fresh tomato, and generously pile on the cooked beef. Serve alongside steamed rice and your zesty dipping sauce for a complete meal!
Optional: Add sliced cucumbers or pickled vegetables on the side for extra freshness.
