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:
-
Rinse the fish thoroughly under cold water. Pat dry with a paper towel.
-
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.
-
Open the fish like a book. You should now see the spine.
-
Remove the backbone carefully, cutting it away from the rib cage. Be gentle to keep both fillets attached at the belly.
-
Trim away the ribs and belly lining, and remove the gills by pulling or cutting them out.
-
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.
