Slow Cooker Pepper Steak

Sure, here’s a recipe for Slow Cooker Pepper Steak:


  • 2 pounds (about 1 kg) beef steak, thinly sliced (sirloin or flank steak works well)
  • 1 onion, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 3 cloves garlic, minced
  • 1/2 cup beef broth or stock
  • 1/4 cup soy sauce
  • 2 tablespoons tomato paste
  • 2 tablespoons brown sugar
  • 1 teaspoon ginger, minced or grated
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon red pepper flakes (adjust to your preferred level of spiciness)
  • 2 tablespoons cornstarch (optional, for thickening)
  • 2 tablespoons water (optional, for cornstarch slurry)
  • 2 green onions, sliced (for garnish)
  • Sesame seeds (for garnish)
  • Cooked rice or noodles (for serving)


  1. In a bowl, whisk together the beef broth, soy sauce, tomato paste, brown sugar, minced ginger, black pepper, and red pepper flakes. This will be your marinade and sauce.
  2. Place the sliced beef in a large resealable plastic bag or a bowl. Pour half of the marinade over the beef, making sure it’s well coated. Reserve the remaining marinade for later.
  3. Refrigerate the marinating beef for at least 30 minutes, but ideally 1-2 hours, to let the flavors infuse.
  4. In the slow cooker, layer the sliced onions, red bell pepper, green bell pepper, and minced garlic.
  5. Place the marinated beef on top of the vegetable layers.
  6. Pour the reserved marinade over the beef and vegetables in the slow cooker.

  1. Cover the slow cooker and cook on low heat for 6-8 hours or on high heat for 3-4 hours. The beef should become tender and the flavors should meld together.
  2. If you desire a thicker sauce, mix cornstarch and water in a small bowl to create a slurry. About 30 minutes before serving, stir the cornstarch slurry into the slow cooker and let it continue cooking until the sauce thickens.
  3. Once the cooking time is complete, taste and adjust the seasoning if needed.
  4. Serve the slow cooker pepper steak over cooked rice or noodles. Garnish with sliced green onions and sesame seeds.
