How to Make Slow Cooker Korean Beef Noodles
Step 1: Make the Flavorful Sauce
Whisk together the soy sauce, brown sugar, sesame oil, rice vinegar, freshly grated ginger, garlic, red pepper flakes if you like a little kick, and beef broth right in the slow cooker. This is your powerhouse marinade—so take a second to enjoy the lovely scent as everything comes together!
Step 2: Add the Beef
Drop the beef chuck roast chunks into the slow cooker and toss them thoroughly in the sauce. This is where the magic begins, as the beef soaks up all that bold, Korean-inspired flavor right from the start.
Step 3: Slow Cook Until Tender
Cover the slow cooker and cook on low for 7–8 hours or on high for 4–5 hours. You’ll know it’s ready when the beef is exceptionally tender—almost falling apart when you poke it. The whole kitchen will smell incredible by this point!
Step 4: Shred the Beef
Carefully lift out the beef and shred it using two forks. This little step helps each piece of meat cling to the luscious sauce, guaranteeing that every bite of Slow Cooker Korean Beef Noodles is packed with flavor.
Step 5: Add Veggies and Thicken the Sauce
Return the shredded beef to the slow cooker, then stir in the shredded carrots, sliced red bell pepper, and your cornstarch slurry. Cover and cook on high for another 15–20 minutes so the sauce can thicken slightly, and the veggies turn perfectly tender-crisp.
Step 6: Cook and Toss in the Noodles
Meanwhile, prepare the noodles according to their package instructions, drain, and then add them straight into the slow cooker. Give everything a good toss—watch as the sauce coats every noodle and strand of beef—then get ready to serve!
How to Serve Slow Cooker Korean Beef Noodles

Garnishes
Don’t skip the classic finishing touches: green onions and sesame seeds showered liberally over each bowl. They aren’t just for looks—their fresh snap and toasty flavor complete this dish beautifully, adding texture and flair.
Side Dishes
Balance out this hearty main with simple sides like lightly steamed broccoli, crisp cucumber salad, or even some kimchi for a little fermented spice. A fresh green salad with a tangy dressing would also be right at home next to Slow Cooker Korean Beef Noodles!
Creative Ways to Present
Try serving the noodles in big, shallow bowls with extra veggies on top for a vibrant touch, or pile high in a family-style platter for gatherings. Small bowls work as part of an Asian-inspired feast alongside dumplings or spring rolls—the possibilities are endless when it comes to showcasing these flavor-packed noodles!
Make Ahead and Storage
Storing Leftovers
Leftover Slow Cooker Korean Beef Noodles store beautifully! Cool everything to room temperature, then transfer to airtight containers. They’ll keep well in the fridge for up to 4 days, making for easy lunches or quick dinners when you need them most.
Freezing
For longer storage, simply freeze the cooled beef and sauce (without noodles) in freezer-safe bags or containers. Add fresh-cooked noodles after reheating for best texture. Stored this way, your delicious Korean beef and sauce will keep for up to 2 months.
Reheating
Reheat portions gently on the stovetop or in the microwave, adding a splash of beef broth or water if needed to loosen the sauce. If you’ve frozen just the beef and sauce, thaw overnight in the fridge before gently reheating and tossing with hot cooked noodles.
FAQs
Can I use a different cut of beef?
Absolutely! While beef chuck roast is ideal for tenderness, you can also use brisket or flank steak. Just keep in mind that leaner cuts might not be quite as juicy, so watch your cooking time closely.
Are rice noodles the only option?
No way! While they add a wonderful silkiness, lo mein noodles, udon noodles, or even regular spaghetti work in a pinch. Feel free to swap based on what you have in your pantry or personal preference.
Is this recipe spicy?
As written, it’s only mildly spicy thanks to the optional red pepper flakes. If you like your Slow Cooker Korean Beef Noodles with extra heat, add more flakes or a squeeze of gochujang for a real kick.
Can I make this recipe gluten-free?
Definitely! Choose gluten-free tamari or coconut aminos in place of soy sauce, and be sure to use gluten-free noodles. The rest of the ingredients are naturally gluten-free, making it easy to adapt.
How can I make this meal even faster?
To shave down the time, prep everything the night before. Combine the sauce and beef in the slow cooker insert, cover, and refrigerate overnight. In the morning, just pop it into the base and start cooking—easy and efficient!
Final Thoughts
If you’re in the mood for something bold, comfy, and utterly delicious, give Slow Cooker Korean Beef Noodles a whirl. It’s a true weeknight hero—full of big flavors and guaranteed to become a fast favorite at your table. I can’t wait for you to try it and share the joy with everyone you love!
