Prawns cook fast and absorb flavour fast. NEVER marinate prawns longer than 30 minutes in acidic marinades — the acid will start "cooking" them and they'll turn rubbery.

How to Make Korean BBQ Prawns Marinade

Combine: Mix all marinade ingredients in a bowl or ziplock bag until well combined.
Prep the prawns: Pat the prawns dry with paper towel. Peel and devein if desired, or leave shell on for extra flavour.
Marinate: Add the prawns to the marinade, making sure every piece is well coated. Refrigerate for 15-30 minutes (no longer!).
Bring to temp: Remove from the fridge 20-30 minutes before cooking to take the chill off.
BBQ: Shake off excess marinade and grill over high heat (220-250°C / 425-480°F) until the internal temperature reaches 63°C (145°F) — opaque and pink.
Rest: Let the prawns rest for 1-2 minutes before serving.

Tips for the Best Korean BBQ Prawns

Don't skip the rest — resting allows the juices to redistribute for a juicier result.
Watch the clock — prawns go from perfect to rubbery in seconds. Pull them off the moment they turn pink and opaque.
Reserve some marinade — set aside a portion before adding raw meat to use as a finishing sauce or baste.
Watch for burning — the sugar in this marinade caramelises quickly. Use medium-high heat and watch closely.

Common Mistakes to Avoid

Marinating too long in acid — more than 30 minutes will start chemically "cooking" the prawns, making them mushy.
Grilling straight from the fridge — cold meat doesn't cook evenly. Let it come to room temperature first.
Using the same marinade as a sauce — never reuse marinade that has touched raw meat. Always reserve a clean portion first.
Overcrowding the BBQ — give each piece space so it sears rather than steams.

How long should I marinate prawns in korean bbq marinade?

Can I use korean bbq marinade on other meats?

Yes! Korean BBQ marinade works well on chicken and beef too. Adjust the marinating time based on the protein — delicate proteins need less time.

Should I marinate prawns in the fridge or at room temperature?

Always marinate in the fridge for food safety. Bacteria multiply rapidly at room temperature. Take the meat out 20-30 minutes before cooking to take the chill off for more even cooking.
