Ingredients

Scale

Meat

  • 2 pounds flank steak, sliced into ¼-inch strips
  • 34 tablespoons cornstarch

Vegetables

  • 1 large green bell pepper, sliced thick
  • 1 large red bell pepper, sliced thick
  • 1 medium onion, sliced thick
  • 1 (14.5 oz) can petite diced tomatoes, with liquid

Sauce

  • ½ cup beef broth (or water)
  • ½ cup soy sauce
  • 23 tablespoons brown sugar, to taste
  • 1 teaspoon Worcestershire sauce
  • 34 garlic cloves, minced
  • 1 teaspoon fresh ginger, peeled and minced
  • 1 teaspoon salt
  • 1 teaspoon black pepper

To Serve

  • Cooked white rice, for serving

Instructions

  1. Coat the Steak: Add the sliced flank steak to your slow cooker and sprinkle the cornstarch evenly over the top. Stir thoroughly until the meat is well coated, helping to thicken the sauce as it cooks.
  2. Add Vegetables: Add in the thickly sliced green and red bell peppers, onion, and the petite diced tomatoes along with their liquid to the slow cooker. For firmer peppers, wait to add them during the last 1–2 hours of cooking to maintain their texture.
  3. Prepare Sauce Mixture: In a small bowl, whisk together the beef broth or water, soy sauce, brown sugar (adjusting sweetness to your taste), Worcestershire sauce, minced garlic, minced fresh ginger, salt, and black pepper until well combined.
  4. Combine and Cook: Pour the sauce mixture evenly over the steak and vegetables in the slow cooker. Cover and cook on LOW for 6 hours or on HIGH for 3 hours, until the beef is tender and the flavors have melded beautifully.
  5. Serve: Stir the contents gently to combine everything just before serving. Serve the pepper steak hot over cooked white rice for a complete and satisfying meal. Enjoy your hearty Crockpot Pepper Steak!

Notes

  • For firmer bell peppers, add them during the last 1–2 hours of cooking instead of at the beginning.
  • You can substitute beef broth with water if you prefer a lighter sauce.
  • Adjust the brown sugar quantity to suit your desired level of sweetness.
  • Slicing the flank steak thinly helps it cook more quickly and become tender in the slow cooker.
  • This recipe can be made a day ahead; flavors often improve after resting overnight in the refrigerator.
