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: Finely dice the onion and gather all the sauce ingredients including gochujang, dark soy sauce, rice vinegar, light brown sugar, garlic ginger paste, tomato paste, and low-sodium beef stock.
- Combine Sauce Ingredients: In the slow cooker, combine the diced onion, gochujang, soy sauce, rice vinegar, brown sugar, garlic-ginger paste, tomato paste, and beef stock, stirring gently to mix all components evenly.
- Add the Beef: Place the whole ox cheek on top of the sauce mixture in the slow cooker, making sure it is mostly submerged in the liquid for even cooking.
- Cook the Beef: Cover and cook on low heat for approximately 8 hours until the beef is tender and easily shredded.
- Shred the Meat: Remove the ox cheek from the slow cooker, shred it finely with forks, then return the shredded beef to the slow cooker, stirring to incorporate it back into the sauce.
- Add Noodles and Coriander: Add the ready-to-use udon noodles and roughly chopped fresh coriander to the slow cooker. Increase the heat setting to high and cook for an additional 25 minutes to warm the noodles and allow flavors to meld.

- Leftovers keep well refrigerated for up to 3 days and reheat gently on the stovetop or microwave.
