Description

This Slow Cooker Korean Beef recipe is a deliciously tender and flavorful dish that simmers for hours to develop rich, savory, and slightly sweet flavors. Featuring tender chuck beef cooked with garlic, ginger, soy sauce, and a hint of chili, this recipe is perfect for a comforting and easy weeknight meal served over steamed rice or noodles.


Ingredients

Beef and Sauce

  • 1 onion, diced
  • 3 tsp garlic, crushed
  • 2 tsp ginger, minced
  • 1 Tbsp rice wine vinegar
  • 2 Tbsp sesame oil
  • ½ cup soy sauce
  • ½ cup beef stock
  • ½ cup brown sugar
  • ¼ tsp red chili flakes
  • 1 kg (2.2 lb) chuck beef, cut into bite-sized cubes

Thickening Slurry

  • 3 Tbsp cornstarch
  • 3 Tbsp water


Instructions

  1. Prepare the Sauce: 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 thoroughly to blend all the flavors evenly.
  2. Add the Beef: Place the bite-sized chuck beef cubes into the slow cooker and toss them in the sauce to ensure every piece is coated for maximum flavor during cooking.
  3. Slow Cook the Beef: Set the slow cooker to low heat and let the beef cook for 8 hours until it becomes tender and easy to shred, allowing the flavors to fully penetrate the meat.
  4. Make Cornstarch Slurry: In a small bowl, mix cornstarch and water until smooth to create a slurry that will thicken the sauce.
  5. Thicken the Sauce: Pour the slurry into the slow cooker, stir to combine, then increase the heat to high and cook for an additional 30 minutes, stirring occasionally, until the sauce thickens to a rich, glossy consistency.
  6. Serve: Once thickened and tender, serve the Korean beef hot over steamed rice or noodles to enjoy a savory, slightly sweet, and comforting meal.

Notes

  • For extra flavor, garnish with toasted sesame seeds and chopped green onions before serving.
  • This dish can be made a day ahead; flavors deepen when refrigerated overnight.
  • Use low-sodium soy sauce to control the saltiness.
  • If you prefer a spicier version, increase red chili flakes or add a dash of gochujang.
  • The cornstarch slurry ensures a perfect, glossy sauce that clings to the beef.
