Why You Will Love This Recipe

This Slow Cooker Korean Beef is an absolute weeknight hero. The magic happens while you are busy with other tasks, as the low and slow cooking process ensures the beef becomes fall-apart tender.

It’s incredibly easy to assemble, requires minimal cleanup thanks to the slow cooker, and freezes beautifully for future meals.

Ingredients

• 3 pounds beef chuck roast, trimmed and cut into 2-inch chunks
• 1/2 cup low-sodium soy sauce
• 1/2 cup packed light brown sugar
• 1/3 cup water or low-sodium beef broth
• 1/4 cup ketchup
• 2 cloves garlic, minced
• 1 tablespoon fresh ginger, grated
• 1 teaspoon sesame oil
• 1/2 teaspoon red pepper flakes (optional, for a little heat)
• 1 tablespoon cornstarch mixed with 2 tablespoons cold water (for slurry)
• Sliced green onions, for garnish
• Toasted sesame seeds, for garnish

Step-by-Step Instructions

1. Place the beef chuck roast chunks into the basin of your slow cooker.
2. In a medium bowl, whisk together the soy sauce, brown sugar, water (or broth), ketchup, minced garlic, grated ginger, sesame oil, and red pepper flakes (if using). Whisk until the brown sugar is mostly dissolved.
3. Pour the sauce mixture evenly over the beef in the slow cooker.
4. Cover and cook on LOW for 7 to 8 hours, or on HIGH for 3.5 to 4 hours, until the beef is extremely tender and shreds easily with a fork.
5. Once cooked, remove the beef from the slow cooker using tongs or a slotted spoon and place it onto a large cutting board. Shred the beef using two forks.
6. To thicken the sauce: Leave the liquid remaining in the slow cooker. Whisk the cornstarch slurry (cornstarch and cold water) together until smooth. Turn the slow cooker setting to HIGH (if it was on LOW) and stir the slurry into the liquid. Cook, uncovered, for 10 to 15 minutes, stirring occasionally, until the sauce thickens significantly.
7. Return the shredded beef to the thickened sauce and toss gently to coat completely.
8. Serve immediately over rice, garnished with sliced green onions and toasted sesame seeds.

Expert Tips / Pro Tips

• Trimming the Fat: While chuck roast is ideal for slow cooking, be sure to trim off any overly thick layers of fat before placing the meat in the slow cooker, as fat doesn’t always render down smoothly.
• Achieving the Best Consistency: Do not skip the cornstarch slurry step! The sauce straight from the slow cooker is thin; adding the slurry at the end is crucial for achieving that thick, glossy coating typical of restaurant-style Korean beef.
• Taste Before Serving: Always taste the sauce after thickening. If it seems too salty, a tiny splash of rice vinegar can brighten the flavor. If it needs more sweetness, add a teaspoon more brown sugar.
• Use High Quality Soy Sauce: Since soy sauce is the backbone of this flavor profile, using low-sodium soy sauce ensures you have control over the salt level, and a decent brand will provide deeper umami flavor.

Variations & Substitutions

• Protein Swaps: This method works wonderfully with pork shoulder (Boston butt) cut into chunks, cooked until shreddable. Chicken thighs can also be substituted, reducing the cooking time slightly.
• Spice Level Adjustment: If you prefer more heat, increase the red pepper flakes, or add one tablespoon of Gochujang (Korean chili paste) into the sauce mixture before cooking.
• Healthier Option: Substitute the brown sugar with maple syrup or honey for a slight shift in sweetness profile, though you may need slightly less liquid, as these sweeteners are more liquid than packed sugar.
• Onion Flavor: Add one large, sliced yellow onion along with the beef; it will break down beautifully and integrate flavor into the overall sauce.

Serving Suggestions

The quintessential way to serve Slow Cooker Korean Beef is piled high over steaming hot jasmine or short-grain white rice to soak up every bit of that savory sauce. For added texture and nutrition, serve alongside steamed broccoli florets or kimchi. For a lighter, low-carb option, serve this beef over cauliflower rice or wrapped in crisp lettuce cups.

Storage, Freezing & Reheating

Storage: Store leftover Slow Cooker Korean Beef in an airtight container in the refrigerator for up to 4 days. Note that the sauce may thicken considerably as it cools.

Freezing: This recipe freezes exceptionally well. Once cooled completely, transfer the beef and sauce mixture into heavy-duty freezer bags or freezer-safe containers, leaving about an inch of headspace. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating: To reheat on the stovetop, place the desired amount in a saucepan over medium-low heat, stirring frequently until heated through and the sauce is loosened. In the microwave, cover loosely and heat in 60-second intervals, stirring in between.

FAQ

What cut of beef is best for this recipe?

Beef chuck roast is highly recommended because it has the necessary connective tissue and fat content that breaks down beautifully during the long, slow cooking process, resulting in extremely tender, shreddable meat.

Can I use artificial sweetener instead of brown sugar?

While you can theoretically replace the sugar, it will significantly alter the texture and caramelization of the sauce. If you must substitute due to dietary restrictions, use a zero-calorie sweetener measured for equivalent sweetness, but be aware that the final sauce consistency might be less viscous.

How long does it take to prep this meal?

The hands-on preparation time is very short, usually under 15 minutes. Most of the time involved is passive while the slow cooker does the work of tenderizing the meat.

Can I make this recipe in an Instant Pot instead?

Yes, you can adapt this recipe for an Instant Pot. Sear the beef first, then add the sauce. Cook on High Pressure for 60 minutes, followed by a Natural Pressure Release (NPR) for 15 minutes before quick releasing any remaining pressure. Thicken the sauce afterward.

Method

 

Instructions

1. Place the beef chuck roast pieces into the basin of a slow cooker.
2. In a medium bowl, whisk together the soy sauce, brown sugar, 1/4 cup water, mirin, sesame oil, minced garlic, grated ginger, and gochugaru (if using). Mix well until the brown sugar is mostly dissolved.
3. Pour the sauce mixture evenly over the beef in the slow cooker, ensuring the meat is well coated.
4. Cover and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the beef is fork-tender.
5. Remove the beef from the slow cooker and place it on a cutting board. Use two forks to shred the meat completely. Set aside.
6. Skim any excess fat from the liquid remaining in the slow cooker. If you desire a thicker sauce, mix the 1 tbsp cornstarch with 2 tbsp cold water to create a slurry. Stir the slurry into the sauce in the slow cooker and cook on high for 10-15 minutes until thickened. (Alternatively, just simmer the sauce on the stovetop if the slow cooker doesn’t allow switching to high).
7. Return the shredded beef to the sauce and toss gently to coat thoroughly. Let it simmer in the sauce for a final 10 minutes to absorb the flavor.
8. Serve the Korean beef hot over steamed white rice or alongside lettuce wraps. Garnish generously with toasted sesame seeds and sliced green onions.

Notes

This beef freezes excellently. For an authentic flavor boost, consider adding 1 teaspoon of Gochujang (Korean chili paste) to the sauce mixture. The slow cooking process makes the meat incredibly tender.
