Ingredients:
- For the Marinade:
- 500g (1 lb) beef sirloin or flank steak, thinly sliced
- 2 tablespoons fish sauce
- 1 tablespoon soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon sugar
- 1 tablespoon cornstarch
- 1 tablespoon vegetable oil
- For the Stir-Fry:
- 2 tablespoons vegetable oil
- 2 stalks lemongrass, finely minced (white part only)
- 4 cloves garlic, minced
- 2 shallots, thinly sliced
- 1 red chili, thinly sliced (optional)
- 1 bell pepper, thinly sliced
- 1 onion, thinly sliced
- 2 tablespoons fish sauce
- 1 tablespoon soy sauce
- 1 teaspoon sugar
- Freshly ground black pepper, to taste
- Fresh cilantro or green onions, chopped (for garnish)
- Cooked rice or noodles, for serving
Instructions:
- Marinate the Beef:
- In a large bowl, combine the fish sauce, soy sauce, oyster sauce, sugar, cornstarch, and vegetable oil.
- Add the thinly sliced beef and mix well to ensure all pieces are coated with the marinade.
- Cover and let it marinate for at least 30 minutes, preferably up to 1 hour, in the refrigerator.
- Prepare the Vegetables and Aromatics:
- Finely mince the lemongrass (use only the tender white part), garlic, and thinly slice the shallots, red chili, bell pepper, and onion.
- Cook the Beef:
- Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat until shimmering.
- Add the marinated beef in a single layer and sear until browned, about 2-3 minutes per side. Do this in batches if necessary to avoid overcrowding the pan.
- Remove the beef from the wok and set aside.
- Stir-Fry the Aromatics and Vegetables:
- In the same wok, add the remaining 1 tablespoon of vegetable oil.
- Add the minced lemongrass, garlic, shallots, and red chili (if using). Stir-fry for about 1-2 minutes until fragrant.
- Add the sliced bell pepper and onion, and stir-fry for another 2-3 minutes until they start to soften.
- Combine and Season:
- Return the cooked beef to the wok.
- Add the fish sauce, soy sauce, and sugar. Stir everything together until well combined and heated through.
- Season with freshly ground black pepper to taste.
- Serve:
- Garnish with chopped fresh cilantro or green onions.
- Serve hot with cooked rice or noodles.
Tips for Success:
- Beef Selection: Choose a tender cut of beef like sirloin or flank steak for the best texture. Freezing the beef slightly can make it easier to slice thinly.
- Marinade Time: Allow the beef to marinate for at least 30 minutes to absorb the flavors fully.
- High Heat: Stir-frying is a quick cooking method, so ensure your wok or skillet is hot before adding the ingredients to achieve a nice sear and maintain the vegetables’ crisp-tender texture.
- Lemongrass Preparation: Peel off the tough outer layers of the lemongrass and use only the tender white part. Mince it finely to release its fragrant oils.
