Ingredients:

  • 2 lbs beef chuck, thinly sliced against the grain
  • 2 tbsp cornstarch
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/2 cup soy sauce
  • 1/2 cup brown sugar, packed
  • 1/4 cup hoisin sauce
  • 1 tbsp sesame oil
  • 1 tbsp fresh ginger, minced
  • 3 cloves garlic, minced
  • 1/2 tsp red pepper flakes
  • 2 stalks green onions, thinly sliced
  • 1 tbsp toasted sesame seeds

Instructions:

  1. Slice the beef chuck into thin strips, about 1/4 inch thick. Make sure you cut across the grain so the meat is easy to chew.
  2. Toss the beef strips in a large bowl with cornstarch, salt, and pepper. Stir until every piece is lightly coated.
  3. Whisk together the soy sauce, brown sugar, hoisin, sesame oil, ginger, garlic, and red pepper flakes in a separate bowl. Stir until the brown sugar is fully dissolved.
  4. Place the coated beef into the slow cooker.
  5. Pour the sauce over the meat. Stir gently to ensure all the beef is submerged in the liquid.
  6. Cover and cook on Low for 8 hours. You can use High for 4 hours, but the Low setting usually results in more tender beef.
  7. Check the meat 30 minutes before the end. It should be tender enough to break with a fork.
  8. If the sauce looks too thin, leave the lid off for the final 30 minutes of cooking to let it reduce and thicken.
  9. Stir the beef one last time to coat it in the glossy sauce.
  10. Garnish with sliced green onions and toasted sesame seeds before serving.
