Step-by-Step Instructions

1. Prepare the Beef

1. In a bowl, toss the thinly sliced flank steak with ¼ cup cornstarch until evenly coated. Let sit for 5 minutes—this helps create a crispy texture.

2. Cook the Beef

2. Heat 2 tbsp avocado oil in a large skillet or wok over medium-high heat.
3. Add the beef in batches, ensuring the pieces are not overcrowded. Sear for 1-2 minutes per side until crispy and browned. Remove from the skillet and set aside.

3. Make the Sauce

4. In the same skillet, add the garlic and ginger and sauté for 30 seconds until fragrant.
5. Pour in the tamari, brown sugar, water, and red pepper flakes (if using). Stir and let the sauce simmer for 2-3 minutes until slightly thickened.

4. Combine and Serve

6. Return the cooked beef to the skillet and toss to coat in the sauce. Cook for another 2 minutes until the sauce fully thickens.
7. Remove from heat and garnish with sliced green onions and sesame seeds (if using).
8. Serve hot over steamed rice or vegetables.
