Ingredients

Instructions

  1. Step 1: Heat 2 tbsp unsalted butter in a large wok or skillet over medium-high heat until melted and hot. Add 12 oz thinly sliced beef sirloin and stir-fry for 3-4 minutes until browned and just cooked through. Remove beef and set aside.
  2. Step 2: In the same wok, add 2 tbsp unsalted butter and 4 minced garlic cloves, sautéing for 30 seconds until fragrant but not browned.
  3. Step 3: Add 3 cups broccoli florets, 2 tbsp water, 1/2 tsp salt, and 1/2 tsp black pepper. Stir-fry for 4-5 minutes until broccoli is bright green and tender-crisp.
  4. Step 4: Return the cooked beef to the wok. Add 2 tbsp low sodium soy sauce and 1 tsp sesame oil. Toss everything together and cook for an additional 1-2 minutes until the sauce coats the beef and broccoli evenly. Serve hot.
