These slow cooker 5-ingredient Korean beef lettuce wraps are one of those easy, dependable recipes that make busy days feel a little more manageable. Flank steak cooks low and slow until it turns tender enough to shred, and a simple mixture of soy sauce, brown sugar, garlic, and a touch of sesame flavor gives it that sweet-savory takeout-style taste people love. Tucked into crisp lettuce leaves, it becomes a fresh, crowd-pleasing meal or party bite that feels special without asking much from the cook.
Serve these lettuce wraps with steamed rice, cucumber salad, kimchi, or a tray of shredded carrots and sliced green onions so everyone can build their own. For a heartier spread, I like to add simple fried rice, edamame, or a bowl of chilled noodles, and if you're setting these out for guests, a platter with extra lettuce leaves and plenty of napkins goes a long way.
Slow Cooker 5-Ingredient Korean Beef Lettuce Wraps
Servings: 6
Ingredients
1 1/2 to 2 pounds flank steak
1/2 cup soy sauce
1/3 cup packed brown sugar
3 cloves garlic, minced
1 tablespoon sesame oil
12 to 16 butter lettuce or romaine leaves
Directions
1. Place the flank steak in the slow cooker. Pour the soy sauce over the meat, then add the brown sugar, minced garlic, and sesame oil on top.
2. Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the beef is very tender and easy to pull apart with a fork.
3. Transfer the beef to a cutting board or large bowl and shred it with two forks. Return the shredded beef to the slow cooker and toss it with the cooking juices.
4. Spoon the warm beef into lettuce leaves and serve right away. If you'd like, set the wraps out on a platter so everyone can help themselves.
Variations & Tips
For picky eaters: Serve the shredded beef with rice instead of lettuce wraps, or let everyone build their own with mild toppings on the side. This is an easy way to make dinner feel interactive without changing the whole recipe.
Make it a little sweeter: If your family likes that classic sweet-savory flavor, stir in an extra spoonful of brown sugar after shredding and let it warm through in the sauce for a few minutes.
Add a little heat: A spoonful of chili paste, a drizzle of sriracha, or a pinch of red pepper flakes can be stirred into the sauce for anyone who wants more kick. I usually keep it mild in the cooker and offer heat at the table.
Use the right lettuce: Butter lettuce is soft and easy to fold, while romaine gives more crunch and holds up well on a party platter. If you're serving a crowd, rinse and dry the leaves well ahead of time so assembly goes faster.
Prep ahead tip: The beef can be cooked, shredded, and refrigerated in its sauce for up to 3 days. Reheat it gently and set out fresh lettuce right before serving so the wraps stay crisp.
