On a cool evening when I want the house to smell amazing and everyone to linger around the table, I make slow cooker Korean beef. The beef turns tender enough to melt in your mouth while a savory sweet soy glaze coats every bite. This recipe is just the fix for a cozy weekend or hands off weekday meal.
I first made this after picking up some marbled beef on sale and it instantly became my go to crowd pleaser. My kids love piling the saucy beef on rice or in lettuce wraps and there are never any leftovers left for the next day.
Ingredients
- Onion diced: Adds sweetness and depth to the sauce. Look for onions with tight skin and no soft spots
- Garlic crushed: Brings sharp aroma and flavor. Always choose fresh firm bulbs
- Ginger minced: Brings a zesty bite. Fresh ginger is best but you can use jarred in a pinch
- Rice wine vinegar: Brightens the overall flavor. Go for clear unseasoned vinegar if you can
- Sesame oil: Gives nutty deep flavor. Toasted sesame oil packs the most punch
- Soy sauce: Foundation of the savory sauce. Use low sodium if you prefer to control saltiness
- Beef stock: Rounds out the marinade with extra richness. Opt for homemade or low sodium brands when possible
- Brown sugar: Adds sweetness and a sticky finish. Dark brown sugar makes the sauce even richer
- Red chili flakes: Gives a gentle kick of heat. Adjust to taste or omit if cooking for kids
- Chuck beef cut into bite sized cubes: Choose well marbled pieces for the best tenderness. Look for bright red meat with some fat streaks
- Cornstarch mixed with water: Thickens the sauce so it coats every morsel. Ensure cornstarch is not expired for best results
Instructions
- Sauté the Aromatics:
- Dice the onion finely and add it straight to the bottom of your slow cooker. Smash and mince the garlic and ginger and scatter them over the onion. Pour in the rice wine vinegar and sesame oil so the pungent notes infuse into the mix
- Mix the Sauce:
- Add the soy sauce, beef stock, and brown sugar. Stir everything thoroughly so the sugar starts to dissolve and the aromatics are evenly distributed
- Add the Beef:
- Cut your beef into bite sized cubes and drop them into the slow cooker. Gently turn the cubes in the sauce mixture so each piece is completely coated and tucked in well
- Slow Cook Until Tender:
- Cover the slow cooker and set it on low for eight hours. During this time the beef will relax and pull apart easily, soaking up all those flavors
- Thicken the Sauce:
- A half hour before serving, mix the cornstarch and water into a smooth slurry. Carefully stir it into the hot beef mixture. Crank your slow cooker to high and let it bubble until the sauce thickens to a shiny glaze
- Serve and Enjoy:
- Ladle the tender beef with its thick glossy sauce over hot rice. Top with sliced green onions and sesame seeds for a finishing touch if you like

I will always remember making a big batch for a family gathering and seeing everyone go back for seconds with big smiles.
Storage Tips
Leftovers keep well in the fridge for up to four days. Store in a sealed glass or plastic container and reheat gently in the microwave or a saucepan. If you want to freeze, let the beef cool completely and portion into freezer bags. Label with the date so you can keep track.
Ingredient Substitutions
No rice wine vinegar? White wine vinegar or apple cider vinegar both work in a pinch. No chuck beef? Try brisket or even boneless short ribs with good marbling for tender results. Need less sugar? Use coconut sugar or reduce the amount to taste. The sauce still comes out flavorful. If gluten is a concern use tamari or coconut aminos instead of traditional soy sauce.
Serving Suggestions
Serve over steamed jasmine or short grain rice for classic comfort. Wrap the beef in crisp butter lettuce leaves with fresh carrot and cucumber for a low carb option. Add a side of quick sautéed bok choy or steamed broccoli to complete the meal.
Cultural and Seasonal Context
Korean beef dishes like this are inspired by bulgogi with its savory sweet notes. Slow cooking is not traditional but works perfectly for busy schedules. This recipe brings a taste of Korean family tables home in a way that fits any season. While this beef is amazing in winter you can lighten it with fresh herbs or pickled vegetables for summer.
Seasonal Adaptations
Serve with steamed sweet corn or grilled zucchini in summer. Top with pomegranate seeds for a winter holiday vibe. Stir in green peas or snow peas in the last half hour for a spring touch.
Success Stories
I have served this beef for big birthday feasts and quiet Sunday dinners. It is the type of dish that wins over both kids and adults and leftovers vanish quickly. A friend once froze a batch and claimed the flavors were even deeper after reheating.
Freezer Meal Conversion
To make this a freezer meal, assemble everything except the cornstarch slurry in a gallon freezer bag. Freeze flat and label with the date. When ready to cook just thaw overnight in the fridge and dump into the slow cooker in the morning.

This Korean beef is simple but full of comfort and bold flavor. Once you try it, it will become a reliable favorite you return to all year long.
