Instructions

1. Step 1: In a small bowl, mix 3 tbsp soy sauce, 1 tsp brown sugar, 1 tsp cornstarch, and 3 tbsp water until smooth to create the stir fry sauce.
2. Step 2: Heat 2 tbsp vegetable oil in a large skillet over medium-high heat. Add 8 oz beef sirloin strips and cook for 3-4 minutes until browned and just cooked through, then remove the beef and set aside.
3. Step 3: In the same skillet, add 1 tbsp sesame oil and 8 oz sliced button mushrooms. Sauté for 5 minutes until mushrooms release their moisture and begin to brown.
4. Step 4: Add 4 minced garlic cloves and sauté for 30 seconds until fragrant, then return the beef to the skillet.
5. Step 5: Pour the prepared soy sauce mixture over the beef and mushrooms. Stir continuously for 2-3 minutes until the sauce thickens and evenly coats the beef and mushrooms.
6. Step 6: Season with 1/4 tsp black pepper and 1/4 tsp red pepper flakes, if using. Garnish with 2 sliced green onions before serving hot with steamed rice or noodles.
