Ingredients (and Why They Matter)

• 2 pounds beef sirloin or flank steak (thinly sliced)
  The star of the dish. These cuts become incredibly tender in the slow cooker and absorb the savory sauce beautifully. Slicing the beef into thin strips helps it cook evenly and soak up all the flavor.
• 2 large bell peppers (any color), sliced
  Bell peppers bring a natural sweetness, bright color, and gentle crunch to the dish. Using a mix of red, yellow, or green peppers creates a more vibrant and flavorful meal.
• 1 medium onion, sliced (optional)
  Onions add depth and natural sweetness as they slowly soften during cooking. They blend perfectly with the savory sauce and enhance the overall flavor profile.
• 3/4 cup low-sodium soy sauce
  Soy sauce forms the base of the sauce and provides the signature umami-rich flavor associated with traditional pepper steak dishes.
• 1/2 cup beef broth
  Beef broth adds richness while balancing the saltiness of the soy sauce, creating a smoother and more well-rounded sauce.
• 2 tablespoons brown sugar
  This ingredient adds subtle sweetness that balances the savory flavors and enhances the caramelized taste of the beef and peppers.
• 2 tablespoons cornstarch (optional)
  Cornstarch thickens the sauce at the end of cooking, turning it into a glossy, restaurant-style gravy that coats the beef perfectly.
• Cooked rice or noodles for serving
  A warm bed of rice or noodles soaks up the rich sauce and completes the meal.

Step-by-Step Instructions

1. Prepare the beef.
   Slice the beef sirloin or flank steak into thin strips. Place the strips evenly in the bottom of your slow cooker.
2. Add the vegetables.
   Layer the sliced bell peppers and onions over the beef. This allows the vegetables to soften and release their natural sweetness as they cook.
3. Make the savory sauce.
   In a small bowl, whisk together the soy sauce, beef broth, and brown sugar until the sugar dissolves.
4. Combine everything.
   Pour the sauce mixture evenly over the beef and vegetables in the slow cooker.
5. Slow cook to perfection.
   Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours. The beef should be tender and the peppers soft.
6. Thicken the sauce (optional).
   Mix the cornstarch with 2–3 tablespoons of cold water to create a slurry. Stir it into the slow cooker during the last 20 minutes of cooking and let the sauce thicken.
7. Serve and enjoy.
   Spoon the pepper steak over freshly cooked rice or noodles and drizzle extra sauce on top for maximum flavor.
