Ingredients

Scale

Main Ingredients

  • 1 onion, diced
  • 3 teaspoons garlic, crushed
  • 2 teaspoons ginger, minced
  • 1 tablespoon rice wine vinegar
  • 2 tablespoons sesame oil
  • ½ cup soy sauce
  • ½ cup beef stock
  • ½ cup brown sugar
  • ¼ teaspoon red chili flakes
  • 1 kilogram (2.2 pounds) chuck beef, cut into bite-sized cubes

Thickener

  • 3 tablespoons cornstarch
  • 3 tablespoons water

Instructions

  1. Prepare the sauce mixture: In a slow cooker, combine the diced onion, crushed garlic, minced ginger, rice wine vinegar, sesame oil, soy sauce, beef stock, brown sugar, and red chili flakes. Stir well to thoroughly mix all the flavors.
  2. Add beef to slow cooker: Add the bite-sized beef cubes into the slow cooker. Toss and stir to ensure all the beef pieces are evenly coated with the sauce mixture.
  3. Cook the beef low and slow: Cover the slow cooker and set it to cook on low heat for 8 hours. This slow cooking will tenderize the beef and allow flavors to meld deeply.
  4. Create thickening slurry: In a small bowl, mix together the cornstarch and water until smooth to make a slurry.
  5. Thicken the sauce: After 8 hours, pour the cornstarch slurry into the slow cooker. Stir to combine, then increase the heat to high and cook for an additional 30 minutes. This will thicken the sauce to a rich consistency.
  6. Serve and garnish: Serve the Korean beef hot, optionally garnished with sliced green onions and sesame seeds for added flavor and texture. Enjoy your hearty slow-cooked meal!

Notes

  • For additional heat, adjust the red chili flakes to taste or add fresh chopped chilies.
  • Serve over steamed rice or with steamed vegetables for a complete meal.
  • Leftovers can be refrigerated for up to 3 days or frozen for longer storage.
  • Substitute chuck beef with brisket or short ribs for different textures and flavors.
