- Cooking: 12 minutes
- Total Time: 27 minutes
Yield
- Serves 4 people
Difficulty Level
- easy to Medium
Ingredients
- For the grilled Fish:
- 4 fillets of firm white fish (such as cod, sea bass, or halibut), skin on
- 2 tablespoons olive oil
- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 lemon, sliced (for grilling and garnish)
- For the Zesty Caper and Red Onion Dressing:
- ½ cup red onion, finely diced
- 3 tablespoons capers, rinsed and chopped
- 2 tablespoons fresh parsley, chopped
- 2 tablespoons extra virgin olive oil
- 1 tablespoon fresh lemon juice
- 1 teaspoon Dijon mustard
- 1 teaspoon honey
- Salt and pepper, to taste
Instructions
- Prepare the Fish: Pat the fish fillets dry with paper towels. Drizzle olive oil over both sides,then season evenly with salt and pepper.
- Grill the Fish: Preheat your grill to medium-high heat (about 400°F/200°C). Place the fish skin-side down on the grill grates. Grill for 4-5 minutes without moving to get a nice sear, then flip carefully and grill for another 3-4 minutes until the fish is opaque and flakes easily with a fork.
- Make the Dressing: While the fish grills, combine the finely diced red onion, chopped capers, and parsley in a medium bowl. In a small bowl, whisk together the olive oil, lemon juice, Dijon mustard, honey, salt, and pepper until emulsified. Pour the dressing over the onion mixture and toss well.
- Rest the Fish: Remove fish from the grill and let it rest for 2 minutes to allow juices to redistribute, enhancing moisture and flavor.
- Serve: Place the grilled fillets on plates,spoon generous amounts of the zesty caper and red onion dressing over each piece,and garnish with grilled lemon slices.
Tips for Success
- Choose firm, thick fillets for grilling to avoid delicate fish drying out or breaking apart.
- Patting fish dry before seasoning prevents sticking and promotes crispy skin.
- To prevent the fish from sticking, oil your grill grates or use a well-seasoned cast iron grill pan.
- If you prefer, swap the red onion for shallots for a milder dressing flavor.
- This dressing can be made ahead and refrigerated for up to 24 hours – allow it to come to room temperature before serving for best flavor.
- Experiment with fresh herbs such as dill or basil for a different aromatic twist.
Serving Suggestions to Impress with Flavor and Presentation
Present your grilled fish atop a vibrant bed of seasonal greens or a light quinoa salad tossed with cherry tomatoes and herbs. Layer the zesty caper and red onion dressing generously to add a punch of brightness. For an elegant touch, garnish with fresh lemon wedges and a sprinkle of finely chopped parsley or microgreens. Pair this dish with a chilled glass of crisp Sauvignon Blanc to enhance the Mediterranean flavors and create an unforgettable dining experience.
