Prepare the Dressing: In a medium bowl, whisk together ¼ cup of olive oil, 2 tablespoons of apple cider vinegar, and 2 crushed garlic cloves. Season generously with sea salt and ground pepper. Then, add in 2 tablespoons of drained capers, 1 thinly sliced red onion, and 2 tablespoons of chopped parsley. Allow the dressing to sit while you cook the fish.

Heat the Pan: Place a large sauté pan over medium-high heat and add 2 tablespoons of olive oil along with 1 tablespoon of butter. Heat until the oil shimmers and the butter is melted, creating a luscious base for cooking.

Cook the Fish: Season 750 grams of fresh fish fillets with sea salt and ground pepper on both sides. Carefully place the fillets into the hot pan, making sure not to overcrowd them. Cook for about 3-4 minutes on each side until the fish is golden brown and flakes easily with a fork.

Drain and Rest: Once the fish is cooked, transfer the fillets to a plate lined with paper towels to absorb any excess oil. Allow them to rest for a minute to enhance tenderness.

Serve the Dish: Arrange the perfectly cooked fish fillets on a serving platter. Spoon the tangy caper and red onion dressing over the top, ensuring each piece is well-coated. Let the fish sit for about 15 minutes.

Complement Your Meal: Serve your Grilled Fish with Caper and Red Onion Dressing alongside a light green salad and some crusty bread.
