Ingredients

Scale

For the Sauce:

  • 3/4 cup hot beef broth
  • 3 beef bouillon cubes
  • 1/4 cup soy sauce
  • 2 teaspoons Worcestershire sauce
  • 2 tablespoons honey
  • 1 teaspoon ground ginger
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt
  • 2 tablespoons cornstarch or flour

For the Pepper Steak:

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

Instructions

  1. Make the sauce: Combine the hot beef broth with beef bouillon cubes in a mixing glass, stirring well to dissolve the bouillon cubes. Add soy sauce, Worcestershire sauce, honey, ground ginger, black pepper, salt, and cornstarch or flour. Stir thoroughly to create a smooth sauce mixture that will thicken during cooking.
  2. Prepare the slow cooker: Place the beef sirloin strips evenly into the slow cooker. Pour the prepared sauce over the beef to coat all pieces.
  3. Add vegetables: Layer the thickly sliced bell peppers, sliced onion, and minced garlic on top of the beef and sauce in the slow cooker, ensuring even distribution for balanced flavors.
  4. Cook the pepper steak: Cover and set the slow cooker to LOW heat for 6 hours or HIGH heat for 3 hours. If possible, stir the ingredients about halfway through cooking to help meld the flavors and ensure even cooking.
  5. Finish and serve: When cooking time is complete, stir the contents well. Transfer the pepper steak to a serving dish and serve hot over rice, noodles, or as a side dish with mashed or baked potatoes for a satisfying meal.

Notes

  • You can substitute cornstarch for flour to keep the sauce gluten-free if desired.
  • For best results, slice the beef and vegetables uniformly to ensure even cooking.
  • Stirring halfway through the cooking process helps prevent sticking and blends flavors better.
  • This recipe can be doubled to serve a larger crowd; just adjust slow cooker capacity accordingly.
  • Leftovers keep well refrigerated for up to 3 days and reheat beautifully.
