Instructions

  1. Step 1: Combine 3 tbsp soy sauce, 1 tsp brown sugar, 1 tsp cornstarch, and 1/4 cup water in a small bowl, stirring until smooth to make the stir-fry sauce.
  2. Step 2: Heat 2 tbsp sesame oil in a large skillet over medium-high heat until shimmering. Add 3 minced garlic cloves and 1 tbsp minced fresh ginger, sauté for 30 seconds until fragrant.
  3. Step 3: Add 12 oz thinly sliced beef sirloin to the skillet, stir-fry for 3-4 minutes until the beef is browned but still tender.
  4. Step 4: Toss in 1 sliced medium red bell pepper and stir-fry for another 2 minutes until the pepper softens but retains some crunch.
  5. Step 5: Pour the prepared sauce over the beef and peppers, stirring constantly for 1-2 minutes until the sauce thickens and coats the ingredients.
  6. Step 6: Season with 1/4 tsp black pepper and sprinkle 2 chopped green onions on top before serving.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep beef sirloin from drying out.

Can I substitute ingredients in Spiced Beef and Roasted Pepper Stir Fry?
