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 Beer Prawns Marinade

  1. Combine: Mix all marinade ingredients in a bowl or ziplock bag until well combined.
  2. Prep the prawns: Pat the prawns dry with paper towel. Peel and devein if desired, or leave shell on for extra flavour.
  3. Marinate: Add the prawns to the marinade, making sure every piece is well coated. Refrigerate for 15-30 minutes (no longer!).
  4. Bring to temp: Remove from the fridge 20-30 minutes before cooking to take the chill off.
  5. 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.
  6. Rest: Let the prawns rest for 1-2 minutes before serving.

Frequently Asked Questions

How long should I marinate prawns in beer marinade?

Marinate prawns in beer marinade for 15-30 minutes maximum. Any longer and the acid will start breaking down the delicate flesh.

Can I use beer marinade on other meats?

Yes! Beer 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.

What temperature should I BBQ beer marinated prawns?

Grill beer marinated prawns over high heat (220-250°C / 425-480°F). Cook until the internal temperature reaches 63°C (145°F) — opaque and pink.
