  • Yield: 6 servings

Ingredients

2 lbs beef sirloin strips or sirloin steak, sliced

3 large bell peppers (red, yellow, or green), sliced thick

1 large onion, sliced

3 garlic cloves, minced

1 1/2 cups beef broth (hot)

2 beef bouillon cubes

1/4 cup soy sauce

2 tbsp Worcestershire sauce

2 tbsp honey

1 tsp ground ginger

1/2 tsp black pepper

1/2 tsp salt

2 tbsp cornstarch or flour

Instructions

  2. Add the sliced beef strips to the slow cooker.
  3. Pour the prepared sauce over the beef in the slow cooker.
  4. Layer the sliced bell peppers, onion, and minced garlic on top of the meat.
  5. Cover and cook on LOW for 6 hours or HIGH for 3 hours. Stir halfway through if possible.
  6. Once cooking is complete, stir everything together and serve hot over rice, noodles, or mashed potatoes.

Notes

  • Add peppers during the last 1–2 hours for firmer texture.
  • Flank or round steak can be used instead of sirloin.
  • No need to brown the meat beforehand.
  • Can be made on stovetop—simmer for 1.5–2 hours on low heat.
  • Use a mix of red, yellow, and green peppers for best flavor and presentation.
  • Dish can be made ahead and tastes even better the next day.
  • Use frozen peppers if needed, but they may be softer.
  • Store leftovers in the fridge up to 4 days or freeze up to 3 months.
  • Reheat in microwave or stovetop until heated through.
  • This dish is kid-friendly and easy to double for larger servings.
