Step-by-Step Instructions

Prepare the Fish
  1. Dry the Fillets: Start by patting each fillet dry with a clean paper towel. Removing excess moisture is crucial to getting a crispy, golden sear on the fish. Moisture can cause the fillets to steam rather than brown.
  2. Season Generously: Sprinkle both sides of the fillets evenly with salt and black pepper. Feel free to adjust the amount of seasoning based on your taste preferences. You can also add a light sprinkle of garlic powder or paprika for additional flavor.
  3. Check for Bones: Run your fingers lightly along the fillets to ensure there are no stray bones. If you find any, use fish tweezers to remove them.
Heat the Skillet
  1. Choose the Right Pan: Use a heavy-bottomed skillet or cast-iron pan for even heat distribution. Avoid nonstick pans as they may not create the same crispy texture.
  2. Heat the Oil: Pour the olive oil into the skillet and heat it over medium-high heat. The oil should shimmer but not smoke. Test if the pan is ready by flicking a few drops of water into the oil—if they sizzle, it’s time to cook.
Sear the Rockfish
  1. Place the Fish Skin-Side Down: Gently lay the fillets into the skillet, skin-side down if applicable (even if skinless, treat one side as the “presentation side”). Press the fillets lightly with a spatula to ensure even contact with the pan, which helps prevent curling.
  2. Cook the First Side: Allow the fillets to cook undisturbed for 3–4 minutes. Avoid flipping too soon—let the fillets develop a deep golden crust.
    • Visual Cue: Look at the edges of the fish as it cooks. When the bottom half turns opaque, it’s ready to flip.
  3. Flip and Finish Cooking: Carefully flip the fillets using a fish spatula or tongs. Cook the second side for another 2–3 minutes, or until the fish flakes easily with a fork.
    • Internal Temperature: If you’re using a food thermometer, the fish should reach an internal temperature of 145°F.
Remove and Rest
  1. Transfer the Fillets: Remove the cooked fish from the pan and place them on a plate or a wire rack to prevent them from getting soggy.
  2. Tent with Foil: Lightly tent the fish with aluminum foil to keep them warm while you prepare the sauce.
Make the Lemon Garlic Butter Sauce
  1. Melt the Butter: Reduce the heat to medium and add the butter to the skillet. Swirl it around until fully melted. Be sure to scrape up any brown bits left in the pan from the fish—these add amazing flavor to the sauce.
  2. Cook the Garlic: Add the minced garlic and sauté for 1 minute, stirring constantly. Garlic can burn quickly, so keep an eye on it and reduce the heat slightly if needed.
  3. Add Lemon Juice and Zest: Pour in the fresh lemon juice and add the zest. Stir to combine, and allow the sauce to simmer gently for 1–2 minutes to meld the flavors. You can taste and adjust the acidity by adding more lemon juice or a pinch of salt.
  4. Incorporate Fresh Parsley: Sprinkle in the chopped parsley and stir for another 30 seconds, just until it wilts slightly. Remove the skillet from the heat.
Combine and Serve
  1. Coat the Fish: Return the cooked rockfish fillets to the skillet, spooning the sauce over each fillet to ensure they’re coated evenly.
  2. Serve Immediately: Plate the fillets and drizzle any extra sauce over the top. Garnish with additional parsley and serve with lemon wedges on the side for an extra burst of flavor.

Variations of the Recipe

  1. Spicy Rockfish: Add a pinch of red pepper flakes or cayenne to the sauce for a hint of heat.
  2. Herb-Crusted Rockfish: Coat the fillets with a mixture of breadcrumbs, Parmesan, and dried herbs before searing.
  3. Citrus Twist: Swap lemon juice with orange or grapefruit juice for a sweeter citrus flavor.
  4. Dairy-Free Option: Use olive oil or coconut oil instead of butter for the sauce.

Serving Suggestions

  • Side Dishes: Pair this rockfish recipe with garlic mashed potatoes, roasted asparagus, or a light quinoa salad. Try serving it alongside this sausage broccoli stir-fry for a balanced, flavorful dinner.
  • Drinks: Serve with a refreshing iced tea, sparkling water with lemon, or a non-alcoholic sparkling cider.
  • Presentation: Plate the fillets over a bed of sautéed spinach or rice pilaf, drizzling extra sauce on top for a professional touch.

Tips for the Best Rockfish

  1. Dry the Fish: Always pat the fillets dry to ensure a crispy, golden crust when searing.
  2. Don’t Overcrowd the Pan: Cook the fillets in batches if necessary, giving each piece enough space to sear evenly.
  3. Check for Doneness: The fish is done when it flakes easily with a fork and is opaque throughout.
  4. Use Fresh Lemon Juice: For the best flavor, squeeze juice from a fresh lemon rather than using bottled juice.
  5. Keep it Warm: If making multiple batches, keep the cooked fillets warm in a low oven (200°F) while preparing the sauce.

Tips for Frying Rockfish

Do You Leave Skin on Rockfish?

Whether to leave the skin on rockfish depends on the cooking method and your personal preference.

When to Leave the Skin On

  • Grilling or Pan-Seared Recipes:
    The skin helps keep the fish moist and prevents it from sticking to the pan or grill. It also adds a delicious crispy texture when cooked properly.
  • Nutritional Benefits:
    Fish skin contains healthy omega-3 fatty acids and collagen, which contribute to the dish’s nutritional value.

When to Remove the Skin

  • Baking or Poaching:
    The skin may become soft and less appealing in these methods, so it’s better to remove it beforehand.
  • Preference for Skinless Fillets:
    If you don’t enjoy the taste or texture of fish skin, it’s easy to peel off before or after cooking.

How to Prepare the Skin

  • If you leave the skin on, ensure it’s scaled and cleaned properly. Pat the skin dry before cooking for the best results.
