How to Make Grilled Korean Flank Steak with Gochujang Marinade Recipe
Step 1: Prepare the Marinade
Start by whisking together the soy sauce, Gochujang chili sauce, ginger paste, garlic paste, brown sugar, and sesame oil in a bowl until everything is fully blended. This harmonious mixture is where the magic begins—the flavors meld together to create that signature Korean flair.
Step 2: Marinate the Flank Steak
Place your flank steak into a dish or a large plastic bag, then pour 3/4 of the marinade over it. Make sure to toss or turn the steak so the marinade coats every inch evenly. Let the steak chill out in the fridge for at least one hour — or better yet, overnight — to soak up all those vibrant flavors nicely and develop extra tenderness.
Step 3: Fire Up the Grill
Preheat your grill or griddle to medium to medium-high heat. This temperature is perfect because it allows you to cook the flank steak quickly, locking in juices while achieving a delightful sear and caramelization from that brown sugar in the marinade.
Step 4: Grill the Steak
Place the marinated steak directly over the heat, grilling it for about 3 to 4 minutes on each side for medium doneness. Be sure to brush the steak with the reserved marinade during grilling to keep it juicy, flavorful, and beautifully glazed with that irresistible sticky finish.
Step 5: Rest and Slice
Once grilled to perfection, let your flank steak rest for a few minutes so the juices settle. Then, slice the steak thinly against the grain to ensure each bite is tender and easy to eat—this step is crucial to maximize that melt-in-your-mouth experience.
Step 6: Optional Dipping Sauce
Mix together the remaining soy sauce and Gochujang to create a tangy, spicy dipping sauce that perfectly complements the savory grilled steak. Drizzle this over your slices or serve it on the side for dipping.
How to Serve Grilled Korean Flank Steak with Gochujang Marinade Recipe

Garnishes
Sprinkle toasted sesame seeds and chopped green onions over the sliced steak to add delightful crunch and vibrant pops of green. These simple touches brighten the presentation and add extra flavor complexity.
Side Dishes
Serve your grilled Korean flank steak alongside steamed jasmine rice or sticky short-grain rice to soak up the marinade’s tantalizing juices. Pair it with quick pickled vegetables or a crisp Asian slaw for a refreshing contrast that balances the spice and richness.
Creative Ways to Present
For a fun twist, assemble the steak into warm lettuce wraps topped with crunchy cucumbers and a drizzle of the dipping sauce. Alternatively, use it as the star ingredient in a bibimbap bowl layered with sautéed veggies, a fried egg, and a zigzag of extra Gochujang sauce for a colorful and hearty meal.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover grilled Korean flank steak tightly in plastic wrap or place it in an airtight container and refrigerate. It will stay delicious for 3 to 4 days, making it perfect for quick lunches or dinner on the go.
Freezing
If you want to keep the steak longer, freezing is a great option. Slice the cooled steak first, then lay the pieces flat in a freezer-safe bag or container. Frozen steak retains good flavor and texture for up to 2 months.
Reheating
Reheat gently in a skillet over low heat or warm it in the microwave with a damp paper towel covering to maintain juiciness. Avoid high heat to prevent drying out; adding a splash of water or broth can help keep it tender.
FAQs
Can I use other cuts of beef instead of flank steak?
Absolutely! While flank steak is ideal because of its texture and ability to absorb marinades, skirt steak or sirloin can also work nicely. Just be mindful of adjusting grilling times based on thickness.
How spicy is this Grilled Korean Flank Steak with Gochujang Marinade Recipe?
The heat level is moderate thanks to the Gochujang chili sauce, which balances spice with sweetness. You can adjust the amount of Gochujang to suit your preference, adding more for extra kick or less for milder flavor.
Can I marinate the steak for less than an hour?
While one hour is the minimum for good flavor infusion, marinating longer—up to overnight—really elevates the tenderness and depth. If short on time, try to at least give it 30 minutes for the basics to absorb.
Is this recipe suitable for grilling indoors?
Yes! You can use a grill pan or an electric griddle indoors to achieve great results. Just preheat your cooking surface well and follow the same timing for grilling.
What should I serve the steak with for a complete meal?
Pair the steak with rice or noodles and a side of pickled or fresh vegetables to create a balanced, satisfying meal with contrasting textures and flavors.
