Ingredients with Measurements
- 1.5 lbs flank steak (680 g)
- 1/4 cup cornstarch (30 g)
- 2 tbsp sesame oil (30 ml)
- 1/2 tsp garlic powder (2.5 g)
- 1/2 cup soy sauce (120 ml)
- 3/4 cup brown sugar (150 g)
- 1 diced onion
- 1/4 tsp red pepper flakes (0.5 g)
Step-by-Step Instructions
1. Prepare the Sauce
In a medium bowl, whisk together the soy sauce, brown sugar, sesame oil, garlic powder, red pepper flakes, and diced onion. This flavorful mixture will be the heart of your Korean beef, providing that perfect balance of sweet, spicy, and savory notes.
2. Prepare the Beef
Pat the flank steak dry with paper towels. Cut it into manageable pieces if necessary. Place the beef in a large bowl and sprinkle the cornstarch evenly over it. Toss gently to coat all sides—this helps tenderize the meat and creates a nice glaze when cooked.
3. Assemble in the Slow Cooker
Place the coated beef into your slow cooker. Pour the prepared sauce mixture over the beef, ensuring all pieces are covered. Cover with the lid and set the slow cooker to low for 6-8 hours or high for 3-4 hours, depending on your schedule.
4. Shred or Cut the Beef
Once the cooking time is up, open the lid and check the beef. It should be tender and easy to shred with two forks or cut into bite-sized pieces. Return the shredded or chopped beef to the slow cooker and stir well to coat with the sauce.
5. Serve & Enjoy!
Serve your Slow Cooker Korean Beef hot over steamed rice, noodles, or even wrapped in lettuce leaves for a low-carb option. Garnish with chopped green onions or sesame seeds if desired. Enjoy the explosion of flavors with every bite!
Presentation & Serving Ideas
- Over Fluffy Rice: Classic and comforting, serve your Korean beef over jasmine or short-grain rice for a hearty meal.
- With Noodles: Toss the beef with cooked soba or udon noodles for a filling Asian-inspired dish.
- In Lettuce Wraps: For a fresh, crunchy twist, spoon the beef into crisp lettuce leaves and top with shredded carrots or sliced cucumbers.
- As a Topping: Use the beef as a flavorful topping for salads or grain bowls for added protein and zest.
How to Store & How Long It Lasts
Store any leftovers in an airtight container in the refrigerator for up to 3 days. For longer storage, transfer the beef and sauce to a freezer-safe container and freeze for up to 3 months. To reheat, simply microwave or warm on the stovetop until heated through. The flavors tend to deepen over time, making leftovers even more delicious!
