Step‑by‑Step Instructions for Grilled Fish with Caper and Red Onion Dressing
Step 1: Prepare the Dressing
In a medium bowl, whisk together ¼ cup of olive oil, 2 tablespoons of apple cider vinegar, and 1 crushed garlic clove. Season the mixture with sea salt and ground pepper to taste, ensuring a balanced flavor. Finally, stir in 2 tablespoons of capers, ¼ cup of thinly sliced red onion, and a handful of chopped fresh parsley. Set the dressing aside to allow the flavors to meld beautifully.
Step 2: Heat the Pan
Place a large sauté pan over medium heat and add 2 tablespoons of olive oil along with a knob of butter. Allow the oil to heat and the butter to melt, creating a shimmering surface in the pan. This combination will enhance the flavors of the grilled fish. Keep an eye on the pan, ensuring it doesn’t smoke—a sign it’s too hot for cooking.
Step 3: Season the Fish
While the pan heats, season your fish fillets, such as snapper or salmon, generously with sea salt and ground pepper on both sides. This step is crucial for ensuring the fish is flavorful throughout. Let the fish sit at room temperature for a few minutes while the pan finishes heating; this helps achieve a perfect sear when cooking.
Step 4: Cook the Fish
Once the sauté pan is hot, carefully place the seasoned fish fillets in the pan. Sauté for about 3-4 minutes on each side, or until the fish turns golden brown and flakes easily when prodded with a fork. Monitor the cooking progress, and avoid overcrowding the pan; cook in batches if necessary to prevent steaming.
Step 5: Rest the Fish
After cooking, gently remove the fish from the pan and place it on a plate lined with kitchen towels. This will absorb any excess oil and keep the fish from becoming soggy. Let the fish rest for a few minutes, enhancing its tenderness while you prepare to plate the dish.
Step 6: Serve with Dressing
Transfer the rested fish fillets to a serving platter and generously spoon the prepared caper and red onion dressing over the top. For the best flavor experience, allow the fish to sit for about 15 minutes before serving. This resting time lets the dressing soak into the fish, providing a delicious and vibrant finish to your grilled fish with caper and red onion dressing.

Expert Tips for Grilled Fish
-
Choose Fresh Fish: Always select the freshest fish available for the best flavor and texture. Look for clear eyes and shiny skin.
-
Let It Rest: Before cooking, allow your fish fillets to come to room temperature. This helps them cook evenly, avoiding a cold center.
-
Don’t Overcrowd the Pan: Cook fish in small batches to ensure it gets a nice golden crust. Overcrowding leads to steaming instead of searing.
-
Monitor Cooking Time: Fish cooks quickly; sticking to about 3-4 minutes per side will help prevent it from drying out. Flake test to check for doneness.
-
Flavor Infusion: For an added punch, let the grilled fish with caper and red onion dressing sit for 15 minutes before serving. It allows the flavors to meld beautifully.
