Ingredients

• 1½ pounds Korean beef flank steak, thinly sliced across the grain (choose USDA Choice)
• ¼ cup low-sodium soy sauce (or tamari for gluten-free)
• 2 tablespoons gochujang (Korean chili paste)
• 2 tablespoons brown sugar or coconut sugar
• 1 tablespoon toasted sesame oil (extra virgin for best flavor)
• 2 cloves garlic, finely minced (or 1 teaspoon garlic powder)
• 1 inch fresh ginger, peeled and grated (about 1 tablespoon)
• 1 small onion, thinly sliced (sweet onion or Vidalia)
• 1 scallion, thinly sliced for garnish
• 1 teaspoon toasted sesame seeds (plus extra for serving)
• 1 teaspoon vegetable oil (for stir-fry)
• Pinch of red pepper flakes (optional, for extra heat)

Tips:
– For even thinner slices, freeze the steak for 20 minutes before cutting.
– Use fresh ginger for bright flavor; jarred ginger works in a pinch.
– Swap brown sugar for honey or maple syrup if you like a floral sweetness.

Directions

1. Marinate the beef: In a shallow bowl, whisk soy sauce, gochujang, brown sugar, sesame oil, garlic, and ginger until sugar dissolves. Add sliced flank steak, toss to coat, and let rest for at least 15 minutes (up to 1 hour in the fridge).
2. Heat the pan: Warm a large skillet or wok over medium-high heat and swirl in the vegetable oil. You want it almost smoking—this seals in juices.
3. Sear the beef: Remove steak from marinade (reserve liquid), then spread in a single layer. Let each side cook for 1–2 minutes without stirring; you’re aiming for a caramelized crust.
4. Add onion & marinade: Push beef to one side, add sliced onion, and cook 1 minute. Pour in reserved marinade and toss everything together. Stir-fry for another 2–3 minutes until sauce thickens slightly.
5. Finish with flair: Sprinkle red pepper flakes if using, then turn off heat. Garnish with scallions and sesame seeds. For an extra pop, drizzle a few drops of sesame oil over the top.
6. Serve hot: Plate over steamed rice, zucchini noodles, or lettuce wraps for a lighter twist.

Servings & Timing

Prep Time: 15 minutes (plus 15–60 minutes marinating)
Cook Time: 10 minutes
Total Time: 40 minutes (with 15-minute marinade)

Variations

• Spicy Beef Bowl: Add a tablespoon of chili crisp for extra heat.
• Bulgogi Twist: Swap gochujang for 2 tablespoons of pear puree and ½ tsp black pepper.
• Keto-Friendly: Serve over cauliflower rice and skip the brown sugar.
• Vegetarian Swap: Use thinly sliced king oyster mushrooms instead of beef.
• Citrus Kick: Stir in 1 tablespoon of rice vinegar and zest of lime.

Storage & Reheating

Store leftover Korean beef in an airtight container in the fridge for up to 3 days. To freeze, place cooled beef in freezer-safe bags for up to 2 months. Reheat gently in a skillet over medium heat or microwave covered for 1–2 minutes—add a splash of water to revive the sauce. Make-ahead tip: Marinate and slice the beef the night before for truly effortless cooking.

Notes

• I learned that thinly slicing the beef on the bias makes every bite melting-tender.
• If your sauce thickens too much, stir in a teaspoon of water or stock.
• For a cleaner sugar caramel, dissolve the sugar in the soy sauce before adding the beef.
• Don’t overcrowd the pan—stir-fry in batches if needed to maintain that perfect sear.

FAQs

Q: Can I prepare this for meal prep?
A: Yes—store beef and side separately, then reheat together to keep veggies crisp.
