To begin, gather all the necessary ingredients for Ina Garten's Halibut recipe. Next, prepare a shallow glass dish by lining it with parchment paper. This will prevent the fish from sticking to the dish.
Place the halibut fillets in the dish, making sure they are arranged in a single layer.In a small bowl, combine the olive oil, lemon juice, minced garlic, chopped parsley, basil, salt, and pepper. Mix the ingredients together well to create a flavorful marinade. Pour the marinade over the halibut fillets, ensuring that each piece is coated evenly. Cover the dish and place it in the refrigerator to marinate for about 1 hour. This will allow the flavors to penetrate the fish.
Preheat your oven to 450°F (230°C). Remove the dish from the refrigerator and pour out the excess marinade.
Place the dish with the marinated halibut fillets in the preheated oven, leaving them uncovered. Bake the fish for approximately 15 minutes or until it easily flakes apart when tested with a fork.
Once the halibut is cooked, remove it from the oven and serve immediately while it's still hot and flavorful. Pair it with your favorite side dishes or enjoy it as is for a delicious seafood meal.
