Ingredients
Beef and Sauce
- 1 large onion, finely diced
- 2 tablespoons gochujang
- 2 tablespoons dark soy sauce
- 2 tablespoons rice vinegar
- 1 tablespoon packed light brown sugar
- 1 tablespoon garlic-ginger paste
- 1 tablespoon tomato paste
- 3 1/2 ounces low-sodium beef stock
- 14 ounces ox cheek (or substitute ox tail, short ribs, or chuck roast)
Noodles and Garnish
- 4 pouches ready-to-use udon noodles
- 1 to 2 tablespoons fresh coriander, roughly chopped
- 1 tablespoon black sesame seeds, for garnish
- Kosher salt and freshly cracked black pepper, to taste
Instructions
- Prepare the Beef: In a slow cooker, combine the finely diced onion, 2 tablespoons of gochujang, 2 tablespoons dark soy sauce, 2 tablespoons rice vinegar, 1 tablespoon packed light brown sugar, 1 tablespoon garlic-ginger paste, 1 tablespoon tomato paste, and 3 1/2 ounces low-sodium beef stock. Mix these ingredients well to create a flavorful base for the beef.
- Cook the Beef: Place the 14 ounces of ox cheek on top of the sauce mixture in the slow cooker. Cook on low heat for 8 hours to allow the beef to become incredibly tender and absorb all the rich flavors.
- Shred the Meat: After 8 hours, shred the cooked beef using two forks, then return the shredded meat back into the slow cooker to soak up the juices and sauce.
- Finish the Dish: Add the 4 pouches of ready-to-use udon noodles and 1 to 2 tablespoons of roughly chopped fresh coriander to the slow cooker. Increase the heat to high and cook for an additional 25 minutes until the noodles are hot and have absorbed some of the sauce.
- Season and Garnish: Season the dish with kosher salt and freshly cracked black pepper to taste. Sprinkle 1 tablespoon of black sesame seeds over the top as a garnish before serving for added flavor and texture.
Notes
- If you prefer, substitute ox cheek with ox tail, short ribs, or chuck roast depending on availability.
- For enhanced flavor, you can marinate the beef in the sauce mixture for an hour before placing it in the slow cooker.
- Use low-sodium beef stock to control the saltiness of the dish.
- Ready-to-use udon noodles save time, but fresh udon or other thick wheat noodles can be used as alternatives.
- Adjust the spice level by adding more or less gochujang according to your taste preference.
- The dish can be garnished with additional fresh herbs or sliced green onions for extra freshness.
