How to Make Cajun Lamb Marinade

  1. Combine: Mix all marinade ingredients in a bowl or ziplock bag until well combined.
  2. Prep the lamb: Pat the lamb dry with paper towel. Trim any excess fat if needed.
  3. Marinate: Add the lamb to the marinade, making sure every piece is well coated. Refrigerate for 4 hours minimum, up to 24 hours for deeper flavour.
  4. Bring to temp: Remove from the fridge 20-30 minutes before cooking to take the chill off. This helps it cook more evenly.
  5. BBQ: Shake off excess marinade and grill over high heat (220-260°C / 425-500°F) until the internal temperature reaches 54-63°C (130-145°F) depending on preference.
