- 3/4 cup brown sugar: Brings a rich sweetness that balances the spice and savory notes.

How to Make Sweet and Spicy Korean Beef Stew Recipe
Step 1: Mix the Sauce Ingredients
Begin by combining the corn starch, sesame oil, garlic powder, soy sauce, brown sugar, diced onion, and red pepper flakes in a mixing bowl. Whisk everything together until it forms a smooth, flavorful sauce. This mix is where all the sweet, savory, and spicy magic starts to happen.
Step 2: Prepare the Beef in your Crockpot
Place the flank steak into your slow cooker, then pour the prepared sauce over the meat, ensuring it’s thoroughly coated. Cover the crockpot and set it to cook low for 6 to 8 hours, or if you’re short on time, cook on high for 3 to 4 hours. This slow cooking tenderizes the beef while letting the flavors meld beautifully.
Step 3: Shred and Return the Meat
Once the cooking time is complete and the beef is fork-tender, carefully remove it from the crockpot. Slice or shred the meat, then return it back to the slow cooker to soak up every last drop of that incredible sauce. This step ensures every bite bursts with flavor.
Step 4: Ready to Serve!
Serve the Sweet and Spicy Korean Beef Stew over fluffy steamed rice, or get creative with your favorite grains. This dish is a guaranteed crowd-pleaser that brings warmth and satisfaction with each spoonful.

Side Dishes
This stew pairs beautifully with a crisp cucumber salad or sautéed greens like bok choy or spinach. The freshness and slight bitterness from the sides balance the rich, sweet, and spicy meat, making every mouthful perfectly enjoyable.
Creative Ways to Present
For a fun twist, serve the stew inside lettuce cups for a handheld delight or spoon it over creamy mashed potatoes for a comforting fusion. You can even turn the leftovers into a Korean beef burrito bowl, layering rice, veggies, and that incredible stew for an innovative meal that tastes just as amazing.
Make Ahead and Storage
Storing Leftovers
This Sweet and Spicy Korean Beef Stew Recipe keeps wonderfully in the fridge for up to 4 days. Store it in an airtight container to maintain the flavors and prevent any moisture loss. The stew actually tastes even better the next day as the flavors continue to deepen.
Freezing
If you want to keep this deliciousness for longer, freezing is a great option. Place the stew in freezer-safe containers or heavy-duty bags, leaving some room for expansion. It will stay good for up to 3 months, making it perfect for meal prepping or quick future dinners.
Reheating
Reheat the stew gently on the stovetop over medium-low heat or in the microwave in short bursts, stirring occasionally. Adding a splash of water or broth helps restore the original saucy texture and ensures every bite is just as tender and flavorful as the first time.
FAQs
Can I use a different cut of beef for this stew?
Absolutely! While flank steak is ideal for its texture and flavor, you can use chuck roast or brisket. Just adjust the cooking time as these cuts may need a bit longer to become tender.
Is it possible to make this stew spicy for those who love heat?
Definitely. Increase the amount of red pepper flakes or add fresh sliced chili peppers to the sauce. Just tailor the spice level to your preference, since the dish balances heat with sweetness beautifully.
Can I make this Sweet and Spicy Korean Beef Stew Recipe on the stovetop?
You can! Brown the beef first in a large pot, then add the sauce and simmer on low heat with a lid on for 2 to 3 hours, stirring occasionally until the meat is tender and the sauce thickens.
What are some alternatives to soy sauce for this recipe?
You can use tamari if you want a gluten-free option or coconut aminos for a slightly sweeter, less salty profile. Both work well while keeping the umami flavor intact.
Is this stew freezer-friendly after shredding the meat?
It is! Shredding the beef before freezing allows the flavors to meld even better after thawing. Just reheat it slowly to keep the meat tender and juicy.
