Instructions

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.
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.
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. 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.

Notes

Do not leave the fish in the pan when it is done. The residual heat from the cast iron will continue to cook the fish.
Try to buy fillets that are similar in size so they cook evenly.

How to Store:

Storage – I like to transfer leftovers to an airtight glass container and keep in the refrigerator for 3-4 days. Or, portion them out into meal prep containers to have for lunches throughout the week.

Reheating – For best results, heat in a pan on the stove so the halibut doesn't dry out. You can also heat in the microwave along with some sides for a full meal at once.
