How to Make Slow Cooker Korean Beef

Step 1: Combine the Sauce

In your slow cooker, add the diced onion, crushed garlic, minced ginger, rice wine vinegar, sesame oil, soy sauce, beef stock, brown sugar, and red chili flakes. Stir everything together until well combined.

Step 2: Add the Beef

Place the cubed chuck beef into the slow cooker, coating it thoroughly with the sauce mixture.

Step 3: Slow Cook

Cover and cook on low for 8 hours, or until the beef is tender and easily shredded with a fork.

Step 4: Thicken the Sauce

In a small bowl, mix the cornstarch with water until smooth to form a slurry. Pour it into the slow cooker and stir to combine. Increase the slow cooker setting to high and cook for 30 more minutes until the sauce thickens to a rich, glossy consistency.

Step 5: Serve

Serve the Korean beef over steamed rice, noodles, or cauliflower rice. Garnish with sliced green onions and sesame seeds for an extra touch of flavor.

Tips for Success

• Use low-sodium soy sauce if you want to control the saltiness
• Skim excess fat from the top of the sauce if desired
• Adjust the brown sugar to your preferred level of sweetness
• Make sure to cut the beef into uniform cubes for even cooking

Equipment Needed

• 5.5L (6 Quart) slow cooker – Adjust ingredients if using a different size
• Small bowl for cornstarch slurry
• Spoon or spatula for mixing
• Knife and cutting board for prepping ingredients

Recipe Variations

• Spicy Version: Add more red chili flakes or a tablespoon of gochujang for extra heat
• Sweet & Savory: Increase brown sugar slightly for a caramelized sauce
• Low-Carb Option: Serve over cauliflower rice instead of white rice
• Vegetable Boost: Add carrots, bell peppers, or broccoli in the last hour of cooking

Serving Suggestions

Serve over steamed jasmine rice, brown rice, or rice noodles. Garnish with toasted sesame seeds, chopped green onions, or a drizzle of sesame oil for an extra flavor boost. Pair with a side of kimchi or sautéed vegetables to complete the meal.
