Ingredients & Instructions
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 chuck beef, cut into bite-sized cubes
- 3 tablespoons cornstarch
- 3 tablespoons water
Step-by-Step Instructions
1. Prepare the Sauce
In your slow cooker, combine diced onion, crushed garlic, minced ginger, rice wine vinegar, sesame oil, soy sauce, beef stock, brown sugar, and red chili flakes. Stir the mixture well to ensure the sugar dissolves and the flavors start to meld.
Tip: Adjust the chili flakes according to your preferred spice level—add more for heat, or reduce for a milder flavor.
2. Add the Beef
Add the bite-sized chuck beef cubes to the slow cooker and toss until each piece is well coated in the sauce. The beef will absorb the sweet and savory flavors during cooking, ensuring each bite is tender and full of flavor.
3. Slow Cook
Cover the slow cooker and cook on low for several hours (usually 6–8 hours) until the beef is fork-tender. The slow cooking process breaks down the meat fibers, creating a melt-in-your-mouth texture without any extra effort.
Pro Tip: If you’re short on time, you can cook on high for 3–4 hours, but low and slow always yields the best tenderness.
4. Thicken the Sauce
In a small bowl, mix cornstarch and water to create a slurry. Pour it into the slow cooker and stir well to combine. Increase the heat to high and cook for another 15–20 minutes until the sauce thickens to a glossy, restaurant-quality consistency.
5. Serve and Enjoy
Serve the Korean beef hot, ideally over steamed white or brown rice. Garnish with sliced green onions or sesame seeds for added texture and flavor. The tender beef combined with the rich, sweet-savory sauce makes each bite utterly satisfying.
