Season fish with garlic powder, salt and pepper, to taste. Set aside.
Pour oil into a large oven-proof skillet to coat the bottom of the pan (about 2 tablespoons). Heat over medium heat. Add butter, let it melt.
Place fish in the oil and butter, skin side down. Cook until bottom is lightly browned (about 3-4 minutes).
Use a spatula to gently turn the fish over.
Place skillet in the oven and bake for about 8 more minutes, or until fish is cooked through and flakes easily with a fork.
Garnish with a squeeze of fresh lemon juice, sprinkle with chopped fresh herbs, and serve.
Notes
Cooking Just for Two? You can easily cut all of the ingredients in half and just cook about 3/4 lb. of fish. The cooking process and time will remain the same.
