Korean Barbecued Flank Steak: A Flavorful Fusion

The first time I tasted truly exceptional Korean barbecue, I was wandering the vibrant streets of Seoul. The air hummed with the sizzle of meats and the intoxicating aroma of garlic, sesame, and soy. But it wasn’t in a fancy restaurant; it was from a small, family-run stall, where the matriarch expertly tended a grill overflowing with marinated meats. One bite of the thinly sliced, impossibly tender beef, bursting with sweet and savory flavors, transported me. Ever since, I’ve been chasing that perfect balance, and this Korean barbecued flank steak recipe comes incredibly close, bringing the essence of those Seoul street flavors to my own kitchen.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 10-16 minutes
• Total Time: 25-31 minutes (plus marinating time)
• Servings: 4-6
• Dietary Type: Varies depending on grill seasoning

Ingredients

• 1 tablespoon grill seasoning, such as McCormick’s Montreal Steak Seasoning
• 1/4 cup tamari, dark soy sauce (regular works also)
• 1 tablespoon honey
• 1 teaspoon red pepper flakes
• 2 large garlic cloves, minced
• 2 teaspoons dark sesame oil
• 2 scallions, finely chopped
• 2 tablespoons vegetable oil
• 2 lbs flank steaks

Equipment Needed

• Shallow dish or ziploc bag
• Indoor electric grill (such as a Foreman grill) or outdoor grill

Instructions

1. In a shallow dish or a plastic ziploc bag, prepare the marinade. Combine the grill seasoning, tamari, honey, red pepper flakes, minced garlic, sesame oil, finely chopped scallions, and vegetable oil. Whisk or shake well to ensure all ingredients are evenly distributed.
2. Place the flank steak into the marinade, ensuring both sides are thoroughly coated. You can gently massage the marinade into the meat.
3. Let the flank steak marinate for at least 10 minutes at room temperature. For deeper flavor, marinate in the refrigerator for several hours or even overnight. If marinating for an extended period, make sure the steak is properly covered to prevent drying.
4. Preheat an indoor electric grill (like a Foreman grill) or an outdoor grill to medium-high heat. Ensure the grill grates are clean and lightly oiled to prevent sticking.
5. Once the grill is hot, carefully place the marinated flank steak onto the preheated grill.
6. Cook for approximately 5 minutes per side for medium-rare. For medium-well, cook for 7-8 minutes per side, or adjust to your preferred level of doneness. Use a meat thermometer to ensure accuracy; 130-135°F for medium-rare, 140-145°F for medium. Note that the internal temperature will continue to rise slightly after removing from the grill. Cooking times can vary depending on the grill used and the thickness of the steak. On a Foreman grill, it may take about 6-8 minutes for medium-rare, depending on your taste.
7. Remove the cooked flank steak from the grill and transfer it to a cutting board. Tent loosely with foil and let it rest for at least 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak.
8. Using a sharp knife, thinly slice the flank steak against the grain. This is crucial for tenderness, as it shortens the muscle fibers.
9. Serve immediately and enjoy!

Expert Tips & Tricks

• Marinating is Key: The longer you marinate the flank steak (within reason, up to 24 hours in the refrigerator), the more flavor it will absorb. However, be mindful that excessive marinating with acidic ingredients (like tamari) can sometimes affect the texture of the meat, making it slightly mushy.
• Achieving a Perfect Sear: Make sure your grill is thoroughly preheated before adding the steak. A hot grill sears the outside quickly, creating a delicious crust while keeping the inside juicy.
• Don’t Overcook: Flank steak is best served medium-rare to medium. Overcooking will result in a tough, chewy texture. Use a meat thermometer to ensure accurate doneness.
• Slice Against the Grain: This is perhaps the most important tip for ensuring a tender final product. Look for the direction of the muscle fibers and slice perpendicular to them.
• Spice Adjustment: Adjust the amount of red pepper flakes according to your spice preference. For a milder flavor, reduce or omit the flakes entirely.
• Marinade as Sauce: After removing the steak from the grill, you can simmer the leftover marinade in a saucepan over medium heat until it thickens slightly. This creates a delicious sauce to drizzle over the sliced steak. Be sure to boil it thoroughly to kill any bacteria from the raw meat.

Serving & Storage Suggestions

Serve the Korean barbecued flank steak immediately after slicing for the best flavor and texture. It’s delicious served with rice, noodles, or a fresh salad. Consider pairing it with Rachael Ray’s Hot and Sour Slaw Salad for a complete and balanced meal.

Leftover cooked flank steak can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm the steak in a skillet over low heat or in the microwave. Be careful not to overcook it, as it can become dry. Adding a splash of water or broth to the skillet or microwave can help retain moisture. You can also enjoy the leftover steak cold in salads or sandwiches. Freezing is not recommended as it will significantly change the texture.

Variations & Substitutions

• Gluten-Free: Ensure the grill seasoning and tamari are gluten-free. Use coconut aminos as a substitute for tamari for a soy-free option.
• Spicy Level: Adjust the amount of red pepper flakes or add a dash of gochujang (Korean chili paste) for extra heat.
• Sweetness: Substitute maple syrup or agave for honey if desired.
• Vegetable Options: Add sliced onions, bell peppers, or mushrooms to the grill alongside the steak for a complete meal. Marinate the vegetables in a small amount of the same marinade used for the steak.
• Citrus Boost: Add a squeeze of lime or lemon juice to the marinade for a brighter flavor.
• Herbal Infusion: Incorporate fresh ginger or lemongrass into the marinade for an aromatic twist.
• Steak Cut: While flank steak is ideal, skirt steak can also be used. Adjust cooking time accordingly.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of soy sauce?
A: Yes, regular soy sauce can be used in place of tamari. However, tamari has a richer, slightly less salty flavor, which complements the other ingredients nicely.

Q: How long should I marinate the flank steak?
A: A minimum of 10 minutes is recommended, but for the best flavor, marinate for at least a few hours or overnight in the refrigerator.

Q: Can I cook this in the oven if I don’t have a grill?
A: Yes, you can broil the flank steak in the oven. Preheat your broiler, place the steak on a broiler pan, and cook for approximately 4-6 minutes per side, depending on the thickness and desired doneness.

Q: What is the best way to slice flank steak?
A: The most important thing is to slice against the grain. This means cutting perpendicular to the muscle fibers. This technique helps to shorten the fibers, making the steak more tender and easier to chew.

Q: Can I freeze the marinated flank steak?
A: Yes, you can freeze the flank steak in the marinade. Place the steak and marinade in a freezer-safe bag, remove excess air, and freeze for up to 2-3 months. Thaw completely in the refrigerator before grilling.
