Bò Lúc Lắc Shaking Beef with Watercress

Ingredients

• 1 lb beef sirloin, cut into 1-inch cubes
• 2 tbsp oyster sauce
• 1 tbsp soy sauce
• 1 tbsp fish sauce
• 2 tsp sugar
• 4 cloves garlic, minced
• 2 tbsp neutral oil
• 1 red onion, sliced into thin wedges
• 3 cups Watercress
• 2 tbsp lime juice
• ½ tsp black pepper, plus more for the dip

Method

1. Toss the beef with oyster sauce, soy, fish sauce, sugar, garlic, and pepper. Let it sit 10 minutes while you make a lime-pepper dip: lime juice, a big pinch of salt, and plenty of coarse pepper.
2. Heat the oil in your widest pan until it shimmers hard. Add the beef in a single layer and leave it alone for 90 seconds — the crust only forms if you don't fuss.
3. Now shake: toss the cubes and sear another 2 minutes for medium-rare centers. Add the onion for the final minute so it stays snappy.
4. Tumble everything over a bed of Watercress — the hot juices wilt it just enough. Serve with the lime-pepper dip and rice.
