What is Slow Cooker Korean Beef?

Slow cooker Korean beef is a simplified, set-it-and-forget-it take on the beloved Korean bulgogi flavors. Instead of thinly slicing and quickly searing meat, this method uses the slow cooker to break down a cut like flank steak until it’s incredibly tender and can be easily shredded. The dish is characterized by its savory, slightly sweet, and deeply umami sauce, which is infused with classic Korean elements like soy sauce, brown sugar, and a hint of garlic.

This recipe captures the essence of Korean BBQ in a way that’s perfect for busy home cooks. The slow cooking process allows the beef to absorb all the delicious marinade, resulting in moist, flavorful meat that practically melts in your mouth. It’s a fantastic way to enjoy Korean-inspired flavors without the fuss of traditional stir-frying, making it a go-to for comforting weeknight meals.

Ingredients Needed to Make Slow Cooker Korean Beef

• 1.5 lbs flank steak (trimmed of excess fat)
• ¼ cup cornstarch
• 2 tablespoons sesame oil
• ½ teaspoon garlic powder
• ½ cup soy sauce (low sodium is great if you prefer)
• ¾ cup brown sugar (packed)
• 1 medium yellow onion (diced)
• ¼ teaspoon red pepper flakes (adjust to your spice preference)

Instructions to Make Slow Cooker Korean Beef – Step by Step

Step 1: Begin by preparing your slow cooker sauce. In a medium bowl, whisk together the cornstarch, sesame oil, garlic powder, soy sauce, packed brown sugar, diced yellow onion, and red pepper flakes. You want to make sure everything is well combined and the brown sugar has started to dissolve into the liquid ingredients, creating a smooth, aromatic marinade. This step is quick, but it’s where all those delicious flavors begin to meld.

Step 2: Next, place the whole piece of flank steak into your slow cooker. It might seem a bit daunting to cook a whole piece, but this is part of the magic! Pour the prepared sauce mixture evenly over the top of the flank steak, making sure it coats the meat as much as possible. This ensures that the beef will be infused with that wonderful Korean BBQ flavor as it cooks.

Step 3: Cover your slow cooker with its lid and set it to cook. For the most tender results, cook on the LOW setting for 6 to 8 hours. If you’re shorter on time, you can cook it on HIGH for about 3 to 4 hours, but the low and slow method really enhances the texture. During this time, the beef will become incredibly tender, and the sauce will thicken beautifully.

Step 4: Once the cooking time is complete and the beef is fork-tender, carefully remove the steak from the slow cooker and place it on a cutting board. You can either shred the meat using two forks until it’s in bite-sized pieces, or thinly slice it against the grain if you prefer a more defined cut. Return the shredded or sliced beef back into the slow cooker with the thickened sauce, and stir to coat every piece.

Step 5: Give everything a good stir to ensure the beef is completely coated in the warm, flavorful sauce. This final step helps the beef soak up any remaining sauce and brings all the elements together beautifully. Your delicious slow cooker Korean beef is now ready to serve and enjoy!

Chef’s Tips for a Perfect Result

• For the most tender beef, always cook on the LOW setting of your slow cooker. This longer cooking time breaks down the connective tissues more effectively.
• Don't skip the cornstarch; it acts as a thickener for the sauce, giving it that desirable glossy finish and ensuring it coats the beef beautifully.
• Taste and adjust the seasoning before serving. You might want a little more soy for saltiness, brown sugar for sweetness, or red pepper flakes for heat.
• Consider trimming excess fat from the flank steak before cooking. This will result in a less greasy dish and a cleaner flavor profile.
• If your sauce seems too thin after shredding the beef, you can mix a tablespoon of cornstarch with two tablespoons of cold water and stir it into the slow cooker on the WARM setting for about 15 minutes until thickened.

Variations and Substitutions

Gluten-Free Alternative:

• What to change: Swap the soy sauce.
• Suggested substitute: Use tamari or a gluten-free soy sauce alternative.
• How it impacts flavor or texture: The flavor profile will remain very similar, especially with good quality tamari.

Spicy Kick:

• What to change: Add more heat.
• Suggested substitute: Increase the red pepper flakes, or add a pinch of gochugaru (Korean chili flakes) or a tablespoon of your favorite hot sauce to the marinade.
• How it impacts flavor or texture: Will result in a spicier dish; gochugaru will add a more authentic Korean heat.

Vegetable Boost:

• What to change: Incorporate vegetables directly into the slow cooker.
• Suggested substitute: Add sliced carrots, bell peppers, or mushrooms during the last hour of cooking.
• How it impacts flavor or texture: Adds extra nutrients and texture to the dish; vegetables will be tender-crisp.

Onion-Free Version:

• What to change: Omit the diced onion.
• Suggested substitute: Use 1-2 teaspoons of onion powder in place of the diced onion.
• How it impacts flavor or texture: Provides onion flavor without the texture of diced pieces; may slightly alter sauce consistency.

How to Serve and Pair

This slow cooker Korean beef is wonderfully versatile. The most classic way to serve it is over a bed of steamed white rice or brown rice, allowing the grains to soak up that delicious sauce. For a more complete meal, pair it with a side of steamed or stir-fried vegetables like broccoli, bok choy, or snap peas. A simple kimchi or a quick pickled cucumber salad also makes a fantastic accompaniment, providing a bright, tangy contrast to the rich beef.

Presentation can be simple yet elegant. Garnish your serving of Korean beef with a sprinkle of sliced green onions and a dusting of toasted sesame seeds for added color and flavor. This dish is perfect for a relaxed weeknight family dinner, a casual get-together with friends, or even for meal prepping lunches throughout the week. It’s a comforting meal that feels special enough for any occasion.

Storage and Reheating

Refrigerator:

• Storage duration: Leftovers can be stored in the refrigerator for up to 5 to 7 days.
• Best storage method: Transfer the cooled beef and sauce into an airtight container. Ensure the container is sealed tightly to prevent air from drying out the meat.
• Tips to preserve texture and flavor: The sauce helps keep the meat moist, so be sure to include plenty of it with your leftovers.

Freezer:

• Storage duration: For longer storage, freeze the Korean beef for up to 2 to 3 months.
• Best storage method: Use freezer-safe airtight containers or heavy-duty freezer bags. Portioning into smaller containers makes reheating easier.
• Tips to preserve texture and flavor: Ensure there’s enough sauce to cover the meat; freezing can sometimes dry out meat.

Reheating:

• Best methods: Reheating on the stovetop or in the microwave are generally best. You can also gently reheat in the oven.
• Practical tips: On the stovetop, heat in a skillet over medium-low heat, stirring occasionally. Add a tablespoon or two of water or broth if the beef seems dry. In the microwave, heat on 50% power, stirring halfway through. If reheating in the oven, place in a covered oven-safe dish at 300°F (150°C) until warmed through, adding a splash of liquid if needed.
