Ingredients You’ll Need
The beauty of this recipe lies in its simplicity yet deliberate choice of ingredients. Each component plays a vital role in building layers of flavor, contributing texture, and giving the stew its iconic Korean-inspired taste and vibrant color.
- 1.5 lbs flank steak: A lean cut that becomes meltingly tender after slow cooking, perfect for shredding.
- 1/4 cup corn starch: Adds subtle thickness and body to the sauce, ensuring it clings beautifully to the meat.
- 2 tbsp sesame oil: Infuses a toasted, nutty aroma that’s signature in Korean dishes.
- 1/2 tsp garlic powder: Provides robust garlicky undertones without overpowering the stew.
- 1/2 cup soy sauce: The salty backbone that deepens the umami and brings harmony to the sweet and spicy notes.
- 3/4 cup brown sugar: Offers a rich sweetness and slight molasses character that balances the heat.
- 1 diced onion: Adds natural sweetness and texture as it slowly softens during cooking.
- 1/4 tsp red pepper flakes: Delivers a perfect kick of heat, awakening the palate without overpowering it.
How to Make Sweet and Spicy Korean Beef Stew Recipe
Step 1: Mix Ingredients
Start by combining all the ingredients except for the flank steak in a mixing bowl. Whisk them well to create a perfectly blended sauce that balances sweet notes from the brown sugar with the savory depth of soy sauce and the warming heat of red pepper flakes. This sauce is the heart of your stew, so take a moment here to enjoy the aromas coming together.
Step 2: Cook in Crockpot
Place your flank steak into the crockpot and pour the prepared sauce over it, ensuring every inch of the meat is bathed in this luscious mixture. Cover the crockpot and set it to cook on low for 6 to 8 hours, which allows the flavors to meld and the beef to become fork-tender. If you’re short on time, cooking on high for 3 to 4 hours works well, but the low-and-slow method is where this stew truly shines.
Step 3: Shred Meat
Once the cooking time is up, carefully remove the steak from the crockpot and shred it using two forks or slice it thinly if you prefer more texture in each bite. Return the shredded meat back into the crockpot and stir it gently to coat it in the sauce, letting it soak up every bit of flavor before serving.
How to Serve Sweet and Spicy Korean Beef Stew Recipe

Garnishes
Adding fresh garnishes transforms your stew into an even more vibrant and inviting dish. Chopped green onions, toasted sesame seeds, and a sprinkle of fresh cilantro brighten the stew’s richness and introduce a delightful contrast in both color and texture.
Side Dishes
This Sweet and Spicy Korean Beef Stew Recipe pairs wonderfully with steamed white rice, which helps mellow out the heat and soak up all that incredible sauce. For a bit of crunch and freshness, serve with quick pickled vegetables or kimchi on the side.
Creative Ways to Present
For a fun twist, try serving this stew over a bed of glass noodles or alongside vegetable pancakes for a Korean-inspired feast. You could also spoon the stew into warm bibimbap bowls, topped with a fried egg to add a rich creaminess that contrasts perfectly with the spicy-sweet flavors.
Make Ahead and Storage
Storing Leftovers
This stew keeps beautifully in the refrigerator for up to four days. Store leftovers in an airtight container to preserve the flavors and prevent the meat from drying out. The flavors often deepen overnight, making your next meal even better.
Freezing
If you want to stretch your batch further, this stew freezes well. Portion it into freezer-safe containers and freeze for up to three months. Thaw overnight in the fridge for the best results and freeze in smaller servings for easy meal prep.
Reheating
Reheat gently on the stovetop over medium-low heat to avoid toughening the meat. Stir occasionally, adding a splash of water or broth if the sauce has thickened too much. You can also microwave individual portions, covering the dish loosely to retain moisture.
FAQs
Can I use a different cut of beef instead of flank steak?
Absolutely! While flank steak is ideal for shredding and absorbs flavors beautifully, cuts like chuck roast or brisket work just as well with slow cooking to create tender, flavorful results.
How spicy is this Sweet and Spicy Korean Beef Stew Recipe?
The heat level is mild to moderate thanks to a quarter teaspoon of red pepper flakes. You can easily adjust the spice to your preference by adding more or less, making this stew versatile for different palates.
Can I make this recipe without a slow cooker?
Yes, you can! Simmer the beef and sauce in a covered pot over low heat on the stove for 3 to 4 hours, or until the meat is tender. Just make sure to check occasionally and add water or broth if the liquid reduces too much.
Is this stew gluten-free?
Traditional soy sauce contains gluten, so to make this stew gluten-free, opt for tamari or a gluten-free soy sauce alternative. Everything else in the recipe is naturally gluten-free.
What’s the best way to thicken the stew if needed?
If you find the sauce too thin after cooking, mix a small amount of cornstarch with cold water and stir it into the stew. Let it simmer for a few minutes until it thickens to your liking.
Final Thoughts
I can’t recommend this Sweet and Spicy Korean Beef Stew Recipe enough for anyone looking to add a new twist on comfort food to their repertoire. It’s incredibly forgiving, full of flavor, and perfect for cozy nights in or feeding a hungry crowd.
