Step 1

In a large skillet heat olive oil over medium high heat. Pat halibut fish dry with paper towel and season all over with garlic powder, onion powder, paprika and salt and pepper.

Step 2

Place the halibut filets in a large (10-inch) cast iron skillet and turn the heat to medium. Sear fish for 3-4 minutes. Flip your fish fillets over to cook the other side. Set aside once the fish is cooked.

Step 3

Reduce the heat to low and add butter in the skillet. When it melts, add garlic. Cook for about 30 seconds or 1 minute. Be careful not to burn the garlic.

Step 4

Gently bring back the fish to the pan. Using a spoon, pour some of the butter sauce left in the skillet onto the halibut fillets before serving. Garnish with fresh rosemary.
