Grilled Fish With Lemon-Caper Sauce: A Taste of Summer

I remember the first time I made this dish. It was a sweltering summer evening, the kind where the air hangs thick and heavy. My friends and I were gathered at my tiny apartment’s rooftop, a makeshift grill precariously balanced on a stack of bricks. Despite the less-than-ideal setup, the grilled fish, bathed in the bright, briny lemon-caper sauce, was a revelation. The smoky char of the grill, the delicate flakes of the fish, and the vibrant sauce – it was pure summer on a plate. That night, surrounded by laughter and good company, this dish became synonymous with easy elegance and the joy of shared meals.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 6
• Dietary Type: Pescatarian

Ingredients

• 2 tablespoons olive oil, divided (add 1/2 tsp if using a disposable aluminum pan to grill your fish in)
• 6 fish fillets, about 2 pounds (red snapper, grouper, amberjack, catfish, or tilapia)
• 1 teaspoon dried dill
• 3⁄4 teaspoon lemon-pepper seasoning
• 1⁄2 teaspoon salt
• 1⁄4 cup onion, chopped
• 1 cup mayonnaise
• 1 (2 ounce) jar pimentos, diced and drained
• 1 tablespoon capers, rinsed
• 1 teaspoon capers, rinsed
• 1 tablespoon fresh parsley, chopped
• 1 tablespoon lemon juice
• 1⁄4 teaspoon black pepper, cracked
• 2 lemons, thinly sliced
• 2 limes, thinly sliced
• Fresh parsley sprig, for garnish

Equipment Needed

• Grill
• Fish grilling basket or disposable aluminum pan (13X9X2 inch)
• Large skillet
• Spatula or stirring spoon
• Serving platter

Instructions

1. First, prepare your grill. If using a fish basket, brush it with olive oil to prevent sticking. If opting for a disposable aluminum pan (13X9X2 inch), brush it with 1/2 teaspoon of olive oil.

2. Place the fish fillets in the prepared basket or pan, ensuring that they do not overlap. This allows for even cooking.

3. Brush the fish fillets with 1 tablespoon of olive oil. This will help them stay moist and develop a nice sear.

4. Sprinkle the fillets generously with dried dill, lemon-pepper seasoning, and salt.

5. Place the pan or basket on the grill rack. Grill, covered, over medium-hot coals for about 25 minutes, depending on the thickness of your fish fillets. Remember, this cook time is for fillets that are approximately 1 inch thick; adjust accordingly.

6. To check for doneness, insert a fork into the thickest part of the fish. It should flake easily when tested. Once cooked through, transfer the fillets to a serving platter and keep them warm. You can tent them with foil if needed.

7. While the fish is grilling, prepare the lemon-caper sauce. In a large skillet, sauté the chopped onion in 1 tablespoon of olive oil over medium-high heat, stirring constantly until the onion becomes tender and translucent. This should take about 3-5 minutes.

8. Remove the skillet from the heat. Stir in the mayonnaise, diced and drained pimentos, 1 tablespoon of rinsed capers, 1 teaspoon of rinsed capers, chopped fresh parsley, lemon juice, and cracked black pepper.

9. Cook the sauce over low heat, stirring frequently, until just heated through. Be careful not to boil the sauce, as this can cause the mayonnaise to separate. This process usually takes about 7 to 10 minutes, so time it carefully according to the cooking progress of your fish.

10. Arrange the thinly sliced lemons and limes attractively around the fish fillets on the serving platter.

11. Garnish with fresh parsley sprigs, if desired. Spoon the warm lemon-caper sauce generously over the fillets and serve immediately.

Expert Tips & Tricks

• Choose the right fish: While this recipe works well with various firm, white fish, consider the thickness of the fillets. Thicker fillets may require a longer cooking time.
• Don’t overcook the fish: Overcooked fish is dry and tough. Use a fork to check for doneness, and aim for a slightly undercooked texture, as the fish will continue to cook slightly off the grill.
• Rinse the capers thoroughly: Rinsing the capers removes excess salt, preventing the sauce from becoming too salty.
• Prepare the sauce ahead of time: The lemon-caper sauce can be made a few hours in advance and gently reheated before serving. This allows the flavors to meld together.
• Grill Marks: For beautiful grill marks, make sure your grill grates are clean and well-oiled. Place the fillets on the grill at an angle, then rotate them slightly after a few minutes to create crosshatched marks.

Serving & Storage Suggestions

Serve the grilled fish immediately, garnished with fresh parsley sprigs and lemon and lime slices. This dish pairs beautifully with a light salad, grilled vegetables (such as asparagus or zucchini), or a simple side of rice or quinoa.

To store leftovers, allow the fish to cool completely before transferring it to an airtight container. Refrigerate for up to 2 days. Reheat gently in a skillet over low heat or in the microwave. Be careful not to overcook the fish when reheating, as it can become dry. It is not recommended to freeze the fish with the sauce as the sauce may separate upon thawing.
