Ingredients

• 500 grams beef sirloin
• 60 ml soy sauce
• 15 grams cornstarch
• 10 grams sugar
• 1 teaspoon black pepper
• 15 ml sesame oil
• 30 ml vegetable oil
• 2 medium onions
• 3 garlic cloves
• 10 grams ginger
• 2 stalks green onions
• 1 red bell pepper
• 60 ml water

Directions

Step 1

Begin by slicing the beef sirloin into thin strips, approximately 1/4 inch thick.

Step 2

In a medium bowl, combine the sliced beef, soy sauce, cornstarch, sugar, and black pepper. Mix well to ensure the beef is evenly coated and set aside to marinate for at least 15 minutes.

Step 3

While the beef is marinating, slice the onions into thin wedges. Mince the garlic cloves and ginger. Cut the red bell pepper into thin strips.

Step 4

Heat a large wok or a heavy frying pan over medium-high heat. Add the vegetable oil and swirl to coat the surface.

Step 5

Once the oil is hot, add the minced garlic and ginger. Stir-fry for about 30 seconds until fragrant.

Step 6

Increase the heat slightly, then add the marinated beef strips. Stir-fry for about 2-3 minutes until the beef starts to brown, and remove from the wok. Set aside.

Step 7

In the same pan, add the sliced onions and red bell pepper. Stir-fry for about 2-3 minutes until they begin to soften.

Step 8

Return the beef to the pan along with any accumulated juices. Add the water and sesame oil. Stir-fry everything together for another 2-3 minutes, ensuring the beef is cooked through and the vegetables are tender-crisp.

Step 9

Adjust seasoning with additional soy sauce or salt if needed.

Step 10

Before serving, sprinkle the sliced green onions over the stir-fry for garnish.

Step 11

Serve hot with steamed rice or noodles, and enjoy your delicious beef stir-fry with onions!
