How to Make Zesty Lemon Butter Fish Fillet: Step-by-Step

Step-by-Step Instructions for Zesty Lemon Butter Fish Fillet

  1. Prepare the Fish:
    Pat your fish fillets dry with paper towels. Season both sides with salt and black pepper. For extra crispiness, lightly coat each fillet in flour and shake off the excess.
  2. Cook the Fish:
    In a large skillet, heat olive oil and 1 tablespoon butter over medium-high. Add fillets and cook for 3–4 minutes per side, until golden and just cooked through. Remove fillets from the skillet and set aside.
  3. Make the Sauce:
    Lower the heat to medium and add 2 tablespoons butter. Stir in minced garlic and sauté for 1 minute until fragrant.
  4. Add the Liquid:
    Pour in the broth and fresh lemon juice, scraping up any browned bits for extra flavor. Let it simmer for 2–3 minutes to reduce slightly.
  5. Finish the Sauce:
    Stir in lemon zest and chopped parsley. Season with a pinch more salt and pepper to taste.
  6. Combine:
    Gently return the fish to the skillet. Spoon the warm, zesty sauce over the fillets and heat through for 1–2 minutes.
  7. Serve:
    Plate the fish, drizzle with sauce, and serve immediately with your favorite sides like steamed vegetables, rice, or salad.

Tips and Twists

  • Dry the fillets well before seasoning for the best crust.
  • Use fresh lemon juice—it makes the sauce shine.
  • Don’t overcook: Fish cooks fast, so watch for opaque flesh and easy flaking.
  • Deglaze the pan with broth for extra flavor.
  • Taste as you go and adjust salt, pepper, or lemon.
  • Variations:
    • Swap in lime or orange for a citrus twist.
    • Add capers for a briny punch.
    • Toss in a handful of cherry tomatoes or thinly sliced shallots for extra flavor.

Storage, Reheating, and Make-Ahead Tips for Zesty Lemon Butter Fish Fillet

  • Storage:
    Store leftover fish and sauce in an airtight container in the fridge for up to 2 days.
  • Reheating:
    Warm gently in a skillet over low heat, adding a splash of broth or lemon juice to keep things moist.
  • Make-Ahead:
    You can prep the lemon butter sauce a day ahead; just reheat gently and finish with parsley and lemon zest before serving. Cook the fish fresh for the best results.
