Ingredients
- 1 lb, thinly sliced against the grain flank steak
- 6 cups, washed fresh spinach
- 1 tbsp, minced ginger
- 3 cloves, minced garlic
- 3 tbsp soy sauce (tamari for gluten free)
- 2 tbsp sesame oil
- 2 tbsp olive oil
- 1/4 tsp red pepper flakes
- 1/2 tsp salt
- 1/4 tsp black pepper
- 2 stalks, sliced thin for garnish green onions
- 1 tbsp, toasted for garnish sesame seeds
Instructions
- Step 1: Heat 2 tbsp olive oil in a large wok or skillet over high heat until shimmering. Add 1 lb thinly sliced flank steak and sear for 2-3 minutes, stirring frequently until beef is browned but still tender. Remove beef and set aside.
- Step 2: In the same skillet, add 2 tbsp sesame oil, 1 tbsp minced ginger, and 3 minced garlic cloves. Sauté for 30 seconds until fragrant, stirring constantly to prevent burning.
- Step 3: Add 6 cups fresh spinach and stir-fry for 2 minutes until wilted but still vibrant green.
- Step 4: Return beef to skillet and pour in 3 tbsp soy sauce (or tamari), 1/4 tsp red pepper flakes, 1/2 tsp salt, and 1/4 tsp black pepper. Toss everything together and cook for 1-2 minutes until sauce coats beef and spinach evenly.
- Step 5: Remove from heat, garnish with 2 sliced green onions and 1 tbsp toasted sesame seeds before serving.
