What Ingredients You Will Need

This recipe calls for straightforward, wholesome ingredients that work harmoniously to bring out bold Korean BBQ flavors and a crisp cucumber kimchi side. Most of these you might already have or can easily grab from your local grocery or Asian market.

For the Korean BBQ Flanken Short Ribs Marinade:

• Flanken-style short ribs, 2 pounds (900g), thinly sliced across the bone
• Soy sauce, 1/2 cup (120ml), low sodium preferred (I like Kikkoman for consistent flavor)
• Brown sugar, 2 tablespoons (adds caramelized sweetness)
• Asian pear juice or grated Asian pear, 1/4 cup (60ml) (tenderizes and sweetens naturally)
• Sesame oil, 1 tablespoon (toasted for depth)
• Garlic, 4 cloves, minced (fresh is best)
• Ginger, 1 tablespoon, grated (fresh and aromatic)
• Green onions, 2 stalks, thinly sliced
• Gochujang (Korean chili paste), 1 tablespoon (optional for a mild kick)
• Black pepper, freshly ground, 1/2 teaspoon

For the Quick Cucumber Kimchi:

• Kirby cucumbers or Persian cucumbers, 2 medium (crisp and small-seeded preferred)
• Salt, 1 tablespoon (to draw moisture out)
• Garlic, 2 cloves, minced
• Gochugaru (Korean chili flakes), 1 tablespoon (adjust for spice level)
• Fish sauce, 1 tablespoon (adds umami depth; substitute with soy sauce for vegetarian)
• Rice vinegar, 2 tablespoons (for tang and brightness)
• Sesame seeds, 1 teaspoon, toasted (adds nuttiness)
• Green onions, 1 stalk, thinly sliced

Feel free to swap gochujang or gochugaru with milder chili powders if you prefer less heat. For a gluten-free version, use tamari instead of soy sauce. Also, if you want a vegan kimchi, leave out the fish sauce and add a splash of seaweed broth for that savory punch.

Equipment Needed

• Grill or grill pan – I prefer a charcoal grill for that authentic smoky flavor, but a cast-iron grill pan works well indoors
• Mixing bowls – for marinating the ribs and preparing the cucumber kimchi
• Sharp knife and cutting board – essential for slicing the ribs and cucumbers thinly and evenly
• Measuring cups and spoons – accurate measurements help balance flavors perfectly
• Colander or strainer – to drain excess moisture from cucumbers
• Plastic wrap or airtight containers – for marinating and storing kimchi

If you’re on a budget, a simple stovetop grill pan and glass mixing bowls will do just fine. Also, keeping your knives sharp makes prep smoother and safer—trust me, I learned that the hard way when a dull blade slipped mid-slice! For toastier sesame seeds, I recommend a small dry skillet rather than the microwave—it gives you more control.

Preparation Method

1. Prepare the marinade: In a large bowl, combine 1/2 cup soy sauce, 2 tablespoons brown sugar, 1/4 cup Asian pear juice, 1 tablespoon toasted sesame oil, minced garlic, grated ginger, sliced green onions, gochujang (if using), and freshly ground black pepper. Stir until sugar dissolves and ingredients blend well. (Approx. 5 minutes)
2. Marinate the ribs: Add the flanken short ribs to the marinade, making sure each piece is well coated. Cover with plastic wrap and refrigerate for at least 1 hour, preferably up to 4 hours for deeper flavor. (If you’re short on time, 30 minutes still works.)
3. Prepare the quick cucumber kimchi: Thinly slice the cucumbers (about 1/4 inch or 0.6 cm thick). Place in a colander, sprinkle with 1 tablespoon salt, toss, and let sit for 20 minutes to draw out excess moisture. Rinse cucumbers under cold water and gently squeeze out any remaining water.
4. Mix kimchi ingredients: In a bowl, combine minced garlic, gochugaru, fish sauce, rice vinegar, toasted sesame seeds, and sliced green onions. Add the drained cucumbers and toss until evenly coated. Set aside to marinate while you cook the ribs (about 15-20 minutes).
5. Prepare the grill or grill pan: Preheat to medium-high heat (about 400°F/200°C). If using a charcoal grill, wait until the coals are covered in white ash.
6. Grill the short ribs: Place the marinated ribs on the grill. Cook about 2-3 minutes per side, depending on thickness, until nicely charred and cooked through but still juicy. Avoid overcooking to keep them tender. (Total grilling time approx. 6-8 minutes)
7. Rest and serve: Transfer ribs to a plate and let rest for 5 minutes. Serve alongside the quick cucumber kimchi for the perfect fresh contrast. Garnish with extra green onions or sesame seeds if desired.

Pro tip: Keep a close eye on the ribs while grilling—they cook fast! If flare-ups happen, move the meat to a cooler part of the grill to avoid burning. Also, don’t skip resting the ribs after grilling; it helps the juices redistribute for that melt-in-your-mouth texture.

Cooking Tips & Techniques

Getting the perfect Korean BBQ flanken short ribs comes down to a few key techniques I’ve learned the hard way:

• Slice the ribs thinly: Flanken style means cutting across the bones in thin strips. This helps marinade absorb quickly and cooks the meat fast without drying out.
• Marinate long enough: While 30 minutes is the minimum, giving the ribs 2-4 hours really boosts flavor and tenderness. The Asian pear juice acts as a natural tenderizer without turning the meat mushy.
• Use medium-high heat: A hot grill creates that signature caramelized crust. Just watch carefully to avoid charring.
• Don’t overcrowd the grill: Give each piece space so heat circulates evenly. Crowding causes steaming rather than grilling.
• Make quick cucumber kimchi fresh: This side is meant to be lively and crunchy, so eat it within 24 hours for best texture and flavor.

One cooking fail I recall: I once tried to rush the ribs on low heat—big mistake! They turned out tough and lacked that smoky char I was craving. Lesson learned: patience and heat are your friends here.

Variations & Adaptations

If you want to play around with this recipe, here are some ideas that work well and keep things interesting:

• Spicy version: Add extra gochujang or finely chopped fresh chili to the marinade for a bolder kick.
• Gluten-free: Swap soy sauce for tamari and ensure gochujang is gluten-free (many brands are, but double-check).
• Vegan adaptation: Use thick slices of king oyster mushrooms or seitan in place of ribs. Marinate and grill the same way for a smoky plant-based BBQ.
• Quick stove-top method: If you don’t have a grill, use a heavy cast iron skillet over medium-high heat. Sear the ribs for the same timing, making sure to get a nice crust.
• Seasonal cucumber swaps: In winter, use pickled radish or carrot kimchi instead for a crunchy side.

Personally, I once tried marinating the ribs overnight with a splash of whiskey in the mix—yielded a subtle depth that wowed my guests at a backyard party. Experiment and find your favorite twist!

Serving & Storage Suggestions

Serve the Korean BBQ flanken short ribs hot off the grill with a generous side of quick cucumber kimchi chilled or at room temperature. The contrast between smoky, sweet meat and bright, tangy kimchi is irresistible.

For a full Korean-inspired meal, add steamed rice and spicy garlic greens for a fresh vegetable side. A cold Korean beer or lightly sweetened iced tea pairs beautifully.

Store leftover ribs in an airtight container in the refrigerator for up to 3 days. The flavor actually deepens, but reheat gently in a skillet or oven to avoid drying out. Keep the cucumber kimchi separate and consume within 24 hours for best crunch and flavor.

If freezing, wrap ribs tightly in foil and place in a freezer bag for up to 2 months. Thaw overnight in the fridge before reheating.
