🐟 Why Red Rockfish?

Red rockfish is a Pacific gem, harvested wild from the cold waters of the North Pacific. What makes it ideal for grilling?

  • Firm, white flesh that stays intact on the grill

  • Mild flavor that works with bold marinades or simple salt and lemon

  • Skin crisps beautifully with heat

  • The head adds moisture and smokiness when cooked whole

  • Budget-friendly compared to snapper or sea bass

🔪 How to Butterfly & Clean a Whole Rockfish (Head-On)

What You’ll Need:

  • Whole red rockfish (scaled)

  • Boning or fillet knife

  • Cutting board

  • Clean running water

  • Paper towels

Step-by-Step Guide:

  1. Rinse the fish thoroughly under cold water. Pat dry with a paper towel.

  2. Lay the fish on its side. Insert your knife along the backbone from the top of the head to the tail—don’t cut through the other side.

  3. Open the fish like a book. You should now see the spine.

  4. Remove the backbone carefully, cutting it away from the rib cage. Be gentle to keep both fillets attached at the belly.

  5. Trim away the ribs and belly lining, and remove the gills by pulling or cutting them out.

  6. Rinse again to remove any blood or guts, and pat dry completely.

💡 Leaving the head on adds dramatic presentation and brings smoky flavor to the grill. It also helps keep the fish moist.

🌶️ Rockfish Marinade: Traditional, Bold & Balanced

This marinade is designed to infuse flavor deep into the fish—especially in those belly and spine areas that soak up seasoning beautifully.

  • 1 tsp black pepper

  • 1 tsp paprika (smoked or sweet)

  • ½ tsp ground coriander

  • ¼ tsp chili flakes (optional)

  • 1 tbsp olive oil

  • 2 cloves garlic, minced

  • 1 tbsp chopped fresh herbs (dill, thyme, or parsley)

Instructions:

  1. Mix all ingredients in a small bowl.

  2. Rub generously inside the fish cavity and on the outside skin.

  3. Place in a zip bag or covered glass dish.

  4. Refrigerate for 24–48 hours for best flavor.

🧊 The longer it marinates, the deeper the flavor—don’t skip this step.
