Ingredients

  • 1 pound beef sirloin, sliced into thin strips
  • 1 large white onion, sliced
  • 3 cloves garlic, minced
  • 1 teaspoon ground ginger
  • 2 cups beef broth
  • 1/4 cup soy sauce
  • 2 tablespoons brown sugar
  • 2 tablespoons cornstarch
  • 1 green bell pepper, sliced
  • 1 red bell pepper, sliced
  • Steamed white rice, for serving

Instructions

  • Prepare the slow cooker by placing beef sirloin, sliced onion, minced garlic, and ground ginger inside.
  • In a bowl, mix beef broth, soy sauce, and brown sugar until sugar dissolves.
  • Pour the sauce over the beef and onion in the slow cooker, coating evenly.
  • Cover and cook on low for 5 hours.
  • After 5 hours, remove 1 cup of cooking liquid, whisk in cornstarch, and return to slow cooker.
  • Add sliced bell peppers, switch to high, and cook for 45 minutes until sauce thickens and peppers soften.
  • Serve over steamed white rice.

Notes

Slice beef against the grain for maximum tenderness
If sauce isn't thickening, mix cornstarch with 2 tbsp water separately before adding
Freshly grated ginger yields better flavor than powdered
