Ingredients

Beef and Vegetables

  • 2 lbs beef sirloin strips (or sirloin steak cut into slices)
  • 3 large colorful bell peppers, sliced thick
  • 1 large onion, sliced
  • 3 garlic cloves, minced

Sauce

  • 3/4 cup hot beef broth
  • 3 beef bouillon cubes
  • 1/4 cup soy sauce
  • 2 tsp Worcestershire sauce
  • 2 tbsp honey
  • 1 tsp ground ginger
  • 1/2 tsp black pepper
  • 1/2 tsp salt
  • 2 tbsp cornstarch (or flour)

Instructions

  1. Make the sauce: In a mixing glass, combine the hot beef broth and crush in the beef bouillon cubes. Add soy sauce, Worcestershire sauce, honey, ground ginger, black pepper, salt, and cornstarch or flour. Stir well until the bouillon cubes dissolve and the mixture is smooth.
  2. Prepare the slow cooker: Place the beef sirloin strips into the slow cooker. Pour the prepared sauce evenly over the beef. Layer the sliced bell peppers, onions, and minced garlic on top of the beef and sauce.
  3. Cook: Cover and set the slow cooker to LOW for 6 hours or HIGH for 3 hours. If possible, stir the ingredients halfway through cooking to ensure even flavor distribution and tenderness.
  4. Serve: After cooking, stir the mixture well and transfer it to a serving dish. Serve hot over cooked rice or noodles, or as a side dish alongside mashed or baked potatoes for a hearty meal.

Notes

  • You can substitute cornstarch with flour for the sauce thickening.
  • Stirring halfway through cooking helps blend flavors and prevents sticking.
  • Adjust the amount of soy sauce and honey according to your taste preference.
  • Adding more vegetables such as mushrooms or snap peas can enhance the dish.
  • Leftovers keep well in the refrigerator for up to 3 days and can be reheated gently on the stovetop or microwave.
