How to Make Zesty Lemon Butter Fish Fillet
1. Season the Fish
Pat the fish fillets dry with paper towels. Season both sides with salt and black pepper.
2. Sear the Fillets
In a large nonstick or cast-iron skillet, heat olive oil over medium-high heat. Place fillets in the pan and cook for 3–4 minutes on each side, or until golden and just cooked through. (The fish should flake easily with a fork.) Remove from pan and set aside on a plate.
3. Make the Lemon Butter Sauce
Reduce heat to medium. Add butter to the same skillet. Once melted, stir in minced garlic and cook for 30 seconds until fragrant. Add lemon juice and zest. Let the sauce simmer for 1–2 minutes to slightly reduce and concentrate the flavor.
4. Return Fish to the Pan
Gently return the fillets to the pan, spooning the sauce over them to coat. Cook for another 1–2 minutes to warm everything through.
5. Finish and Serve
Sprinkle with chopped parsley and garnish with lemon slices if desired. Serve immediately with your favorite sides.
