🛒 Ingredients
🥩 For the Beef
- 1 lb flank steak or sirloin, thinly sliced against the grain
- ¼ cup cornstarch
- 2 tbsp vegetable oil (for searing)
🧄 Sauce
- ½ cup low-sodium soy sauce
- ⅓ cup brown sugar
- ½ cup water
- 4 cloves garlic, minced
- 1 tsp grated fresh ginger
- 2 tsp sesame oil (optional)
🌿 Garnish
- 2 green onions, sliced
- Sesame seeds (optional)
- Cooked rice or noodles, for serving
👩🍳 Directions
Step 1: Prep the Beef
- Toss beef slices with cornstarch until evenly coated. Let sit for 10 minutes—this gives the beef a light crust when cooked.
Step 2: Make the Sauce
- In a bowl or measuring cup, mix soy sauce, brown sugar, water, garlic, ginger, and sesame oil. Set aside.
Step 3: Sear the Beef
- Heat oil in a large skillet or wok over medium-high heat.
- Add beef in batches and sear for 2–3 minutes per side until crispy and browned. Remove to a plate.
Step 4: Simmer the Sauce
- In the same pan, pour in the sauce mixture. Bring to a simmer and cook 3–4 minutes until slightly thickened.
- Return the beef to the pan and toss to coat in the sauce. Heat through for another 2 minutes.
Step 5: Serve
- Serve hot over rice or noodles. Garnish with green onions and sesame seeds.
