How to Make Slow Cooker Korean Beef Noodles Recipe
Step 1: Prepare the Beef and Sauce
Start by combining the finely diced onion, gochujang, dark soy sauce, rice vinegar, light brown sugar, garlic ginger paste, tomato paste, and low-sodium beef stock directly in your slow cooker. This mixture forms a complex, flavorful sauce that will slowly infuse into the beef. Next, place your ox cheek on top of the sauce, ensuring it’s nestled well—it will soak up all those wonderful flavors as it cooks.
Step 2: Cook the Beef Low and Slow
Set your slow cooker to low and let it work its magic for 8 hours. This long, gentle cooking method is what transforms tough cuts like ox cheek into beautifully tender, shreddable meat. The slow stew melds the spicy, sweet, and savory sauce with the beef’s richness, creating an irresistible depth of flavor that’s truly the heart of this Slow Cooker Korean Beef Noodles Recipe.
Step 3: Shred the Beef and Return to the Slow Cooker
Once the beef is fall-apart tender, carefully shred it using two forks. Return all that lovely shredded meat back into the slow cooker, stirring it through the flavorful liquid. This step ensures every bite of meat is perfectly coated and juicy.
Step 4: Add Noodles and Fresh Coriander
Add the ready-to-use udon noodles and chopped fresh coriander to the slow cooker, then change the setting to high and cook for an additional 25 minutes. This allows the noodles to soak up the sauce and warm through without overcooking. Before serving, season the dish with kosher salt and freshly cracked black pepper to taste, enhancing the layers of flavor.
Step 5: Garnish and Serve
Finish off your Slow Cooker Korean Beef Noodles Recipe by sprinkling a tablespoon of black sesame seeds over the top. The sesame seeds add a satisfying crunch and a nutty aroma that complements the dish perfectly, completing this comforting, restaurant-quality meal made effortlessly at home.
How to Serve Slow Cooker Korean Beef Noodles Recipe

Garnishes
Fresh garnishes really lift this dish to the next level. Beyond the black sesame seeds, consider adding extra fresh coriander or even thinly sliced spring onions for a burst of color and brightness. A small drizzle of toasted sesame oil can also heighten the flavor notes, making each bowl feel special and beautifully balanced.
Side Dishes
This Slow Cooker Korean Beef Noodles Recipe pairs wonderfully with simple, fresh sides that won’t compete with the main dish. Think steamed or roasted vegetables like bok choy or broccoli for added green crunch. A crisp cucumber salad or kimchi can add a refreshing, acidic contrast that perfectly complements the rich beef.
Creative Ways to Present
To make your meal feel even more fun and inviting, serve the beef noodles in individual rustic bowls, letting guests customize their portions of garnishes at the table. You can also spoon some of the beef mixture over rice for a hearty variation or wrap it in lettuce leaves for a low-carb, handheld delight. The versatility of this recipe makes it a crowd-pleaser in many forms.
Make Ahead and Storage
Storing Leftovers
Leftover Slow Cooker Korean Beef Noodles Recipe keeps beautifully in the fridge for up to 3 days. Store it in an airtight container to preserve moisture and prevent the noodles from drying out. When ready to eat, you may need to add a splash of broth or water to loosen the sauce during reheating.
Freezing
You can absolutely freeze this dish, which makes it perfect for meal prep or busy weeknights. Freeze portions in freezer-safe containers or bags for up to 2 months. Just keep in mind that the noodles may soften slightly once thawed, so it’s best to consume within that timeframe for optimal texture.
Reheating
To reheat, gently warm the leftovers on the stove over medium-low heat, stirring occasionally and adding a bit of water or beef stock if needed. Avoid overheating as it can cause the noodles to become mushy. Reheating in the microwave works too—just cover loosely and heat in short intervals, stirring between each.
FAQs
Can I use other cuts of beef for this recipe?
Absolutely! While ox cheek is ideal for its rich texture, you can substitute with ox tail, short ribs, or chuck roast. Just be sure the cut you choose is suitable for slow cooking to ensure tenderness.
What if I can’t find gochujang?
If gochujang is not available locally, you can substitute with a mix of miso paste and chili paste, adjusting quantities to your heat preference. However, gochujang provides a unique sweet-spicy character that’s hard to replicate exactly.
Can I make this dish without a slow cooker?
Yes, you can use a heavy pot or Dutch oven on low heat on the stove, cooking for several hours until the beef is tender, or use a pressure cooker to expedite the process. Just be mindful that slow cooking allows the flavors to develop gradually.
Are udon noodles the best choice for this recipe?
Udon noodles are perfect because of their thick, chewy texture that stands up well to the robust sauce. However, if you prefer, you could use other noodles like soba or even rice noodles, keeping in mind that cooking times and texture will vary.
How spicy is the Slow Cooker Korean Beef Noodles Recipe?
The dish has a moderate level of heat thanks to the gochujang, balanced by sweet and savory elements. Adjust the amount of gochujang if you prefer more or less spice. It’s a warm, inviting dish rather than overpoweringly spicy.
