6 tablespoons olive oil
3 small garlic cloves, peeled and minced
1 teaspoon dried basil (or other herbs, to taste)
1 teaspoon salt
1 teaspoon black pepper
2 tablespoons lemon juice
4 6-ounce halibut fillets, skin removed
1 tablespoon light olive oil or vegetable oil
Chopped parsley, for garnish, optional

In a large sealable plastic bag, combine the 6 tablespoons olive oil, garlic, basil, salt, pepper and lemon juice. Add fish, seal bag, and turn to coat. Refrigerate for at least 30 minutes or up to 2 hours.

In a large flat skillet (do not use a ridged pan), pour light olive oil or vegetable oil, tilting pan to spread evenly. Warm over medium-high heat until almost smoking, then add fish fillets. Brush top and sides with marinade. Cook until seared, about 3 minutes; turn and sear other side, about 3 more minutes. Brush top and sides with marinade again. Reduce heat to medium. Cook until centers of fillets are just opaque, 2 to 4 minutes more on each side depending on thickness, brushing with marinade as before. Garnish with parsley, if desired, and serve.
