How to Make Grilled Fish with Caper and Red Onion Dressing

  1. Whisk together the olive oil, apple cider vinegar, and crushed garlic in a bowl. Don’t shy away from seasoning generously with sea salt and ground pepper. Stir in the capers, thinly sliced red onion, and chopped parsley. Set the dressing aside to allow the flavors to blend beautifully.

  2. Heat up a large sauté pan over medium-high heat and add a generous amount of olive oil along with a knob of butter. Season the fish fillets with sea salt and ground pepper, then carefully place them in the pan. Cook for about 4-5 minutes on each side until they’re golden brown and just cooked through. Remember, it’s okay to work in batches if your pan is too small.

  3. Drain the cooked fish on kitchen towels to absorb any excess oil, then transfer to a large lipped platter. This will help keep any juices contained, adding to the flavors.

  4. Spoon the dressing generously over the warm fish and let it sit for 15 minutes. This resting time allows the dressing to soak into the fish, enhancing every bite with its delicious flavors.

Optional: Serve with a wedge of lemon for an extra burst of freshness.

Expert Tips for Grilled Fish with Caper and Red Onion Dressing

Choose Fresh Fish: Opt for fresh, high-quality fish fillets for the best flavor and texture. Avoid pre-packaged if possible.

Perfectly Seasoned: Season your fish well with sea salt and ground pepper before cooking. This enhances the fish’s natural taste and complements the dressing.

Avoid Overcooking: Watch the cooking time closely—overcooked fish can become dry. Aim for a golden crust while keeping it moist inside.

Let It Rest: After plating, let the dressed fish sit for 15 minutes before serving. This allows the dressing’s flavors to meld beautifully into the grilled fish.

Grilled Fish with Caper and Red Onion Dressing Recipe FAQs

What type of fish should I use for this recipe?
Absolutely! I recommend using firm, white fish like cod, halibut, or tilapia, as these hold up well during cooking and pair beautifully with the dressing. If you’re feeling adventurous, salmon or trout can also work wonderfully, bringing a richer flavor to the dish.

How should I store leftovers from this grilled fish recipe?
Very good question! Allow the leftover grilled fish to cool to room temperature, then place it in an airtight container. It will keep in the fridge for up to 3 days. I often keep the dressing separate to maintain its bright flavors and freshness. If you’re worried about sogginess, this is a great approach!

Can I freeze the grilled fish with caper and red onion dressing?
Yes, you absolutely can freeze it! Wrap the grilled fish fillets tightly in plastic wrap and then in aluminum foil to prevent freezer burn. They will stay good for up to 2 months. To reheat, simply thaw overnight in the fridge and warm in a skillet over low heat or in the microwave until heated through.

How can I tell if the fish is cooked properly?
Great question! The fish is done when it flakes easily with a fork and is opaque throughout. If you have a meat thermometer, the internal temperature should reach about 145°F (63°C). Be careful not to overcook; otherwise, it can become dry. Remember, the fish should have a nice golden color on the outside while remaining tender on the inside.

Can I make this dish gluten-free or cater to other dietary restrictions?
Absolutely, and the more, the merrier! This grilled fish with caper and red onion dressing is naturally gluten-free as it contains no wheat products. If you have certain allergies, just check the specific brands of olive oil and condiments to ensure they’re allergy-friendly. Additionally, you can customize the dressing by swapping capers with olives for a milder flavor, which might suit different preferences.

How ripe should my ingredients be?
For optimal flavor, select fresh ingredients. Look for bright green parsley and firm, vibrant red onions. The garlic should be plump; avoid any cloves with dark spots. The fresher the ingredients, the better the final dish will taste!
