Step 1: Preparing the Beef
Slice the flank steak thinly against the grain to ensure tenderness.
Sprinkle ¼ - ½ tsp baking soda over the beef and let it sit for 15 minutes to tenderize. Rinse off thoroughly.
Marinate the beef with 2 tsp soy sauce and coat it with 2 - 2.5 tbsp tapioca or arrowroot starch.
Step 2: Stir-Frying the Beef
Heat 1.5 tbsp avocado oil in a 12-inch pan or wok over medium-high heat.
Add the beef in a single layer and let it sear for about 2 minutes until caramelized.
Flip the beef and cook for another 1 minute, then remove from the pan and set aside.
Step 3: Making the Garlic Sauce
In a small bowl, mix chicken stock, soy sauce, honey, rice wine vinegar, and ¼ cup water.
In a separate small bowl, mix ½ tbsp cornstarch with 1 tbsp water to create a slurry.
Heat 1 tbsp sesame oil in the same pan over medium-high heat.
Add minced garlic and minced ginger, sautéing for 15-30 seconds until aromatic.
Pour in the sauce mixture while stirring constantly to prevent lumps. Let it thicken.
Step 4: Bringing Everything Together
Return the seared beef to the pan, stirring to coat evenly with the sauce.
If using, add bean sprouts and diced scallions, cooking for 30 seconds.
Serve hot with steamed rice, brown rice, or noodles.
