Essential Ingredients

Here’s what you need to make Zesty Lemon Butter Fish Fillets at home:

• 4 white fish fillets (cod, tilapia, halibut, haddock, or snapper) – Fresh or frozen (thawed)
• 2 tablespoons unsalted butter – Can substitute with olive oil for a lighter version
• 2 tablespoons fresh lemon juice – About 1 lemon’s worth; bottled juice works in a pinch
• 1 teaspoon lemon zest – Optional but boosts the citrus flavor
• 2 cloves garlic, minced – Fresh garlic gives the best aroma, but garlic powder works too
• 1 tablespoon fresh parsley, chopped – Basil, dill, or cilantro also work well
• Salt and black pepper – To taste
• 1 tablespoon olive oil – Helps prevent butter from burning
• Lemon wedges – For serving

Substitutions and Variations:

• Fish choice: If you can’t find white fish, salmon works beautifully with lemon butter.
• Herbs: Swap parsley for dill for a more delicate flavor.
• Dairy-free: Use vegan butter or olive oil instead of regular butter.
• Extra zest: Add a sprinkle of red pepper flakes for a subtle heat.

Step-by-Step Instructions

Step 1: Prepare the Fish

1. Pat the fillets dry with a paper towel to remove extra moisture. This helps them sear better.
2. Season both sides generously with salt and black pepper.

Tip: Drying the fish ensures the butter doesn’t sputter too much in the pan and gives you a nice, even sear.

Step 2: Heat the Pan

1. Place a large skillet over medium heat.
2. Add olive oil and butter. The olive oil helps keep the butter from browning too fast.

Tip: Use a stainless steel or non-stick skillet to prevent sticking.

Step 3: Cook the Fish

1. Once the butter is melted and foamy, gently lay the fillets in the skillet.
2. Cook for about 3–4 minutes per side, depending on thickness, until the flesh is opaque and flakes easily with a fork.
3. Remove fish from the pan and set aside on a warm plate.

Tip: Avoid moving the fish around too much while cooking. Letting it sit helps develop a nice crust.

Step 4: Make the Lemon Butter Sauce

1. Lower the heat to medium-low.
2. Add minced garlic to the same pan and cook for 30 seconds, stirring so it doesn’t burn.
3. Stir in lemon juice and lemon zest. Let it bubble for about 1 minute.
4. Taste and adjust seasoning if needed.

Tip: If you like extra sauce, double the lemon juice and butter amounts.

Step 5: Combine and Serve

1. Return the fish to the pan and spoon the lemon butter sauce over the fillets.
2. Sprinkle with fresh parsley.
3. Serve with lemon wedges on the side.

Assembly & Presentation Tips

• Serve the fillets over a bed of steamed vegetables, rice, or pasta to soak up the sauce.
• Garnish with thin lemon slices or twists for a fresh, bright look.
• A sprinkle of fresh herbs at the very end keeps the dish vibrant and aromatic.

Serving Suggestion:
Pair with garlic roasted potatoes and a crisp green salad for a complete meal.

Storage and Make-Ahead Tips

• Refrigerate: Store leftovers in an airtight container for up to 2 days.
• Reheat: Warm gently in a skillet over low heat with a splash of water or extra lemon juice to prevent dryness. Avoid microwaving for too long, as it can make the fish tough.
• Make-ahead: You can prep the lemon butter sauce up to 1 day in advance and store it in the fridge. Reheat it gently before pouring over freshly cooked fish.

Recipe Variations

1. Garlic Herb Butter Fish: Add rosemary, thyme, and oregano for a deeper herb flavor.
2. Spicy Lemon Butter Fish: Mix in cayenne pepper or chili flakes for a kick.
3. Mediterranean Style: Add olives, capers, and cherry tomatoes to the skillet before serving.
4. Baked Version: Instead of pan-searing, place the fillets in a baking dish, top with lemon butter, and bake at 375°F (190°C) for 12–15 minutes.
