Easy Zesty Lemon Butter Fish Fillet is the kind of dinner that feels nicer than the work it asks from you. The fish stays tender, the sauce is glossy and sharp with lemon, and everything happens in one skillet.
I like this with cod, tilapia, haddock, or any mild white fish that looks fresh at the counter. The real trick is simple. Dry the fillets well, cook them just until they flake, and let lemon zest do as much work as the juice.
Easy zesty lemon butter fish fillet
Use mild white fish that smells clean and feels firm, not mushy. Fresh lemon matters here because the zest gives the sauce its sharp, sunny flavor without making it sour.
Ingredients
- For the fish
- 4 white fish fillets, about 6 oz (170 g) each, such as cod, tilapia, haddock, or snapper
- 3/4 teaspoon fine sea salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon paprika
- 2 tablespoons olive oil
- For the lemon butter sauce
- 3 tablespoons (42 g) unsalted butter
- 3 garlic cloves, minced
- 1/4 cup (60 ml) low-sodium chicken broth or vegetable broth
- 2 tablespoons fresh lemon juice
- 1 teaspoon finely grated lemon zest
- 1/4 teaspoon red pepper flakes, optional
- 1 tablespoon capers, drained, optional
- 2 tablespoons chopped fresh parsley
- Lemon slices, for serving
Instructions
1. Season the fish: Pat the fish fillets dry on both sides. Season with salt, pepper, and paprika.
2. Sear the fillets: Heat olive oil in a large nonstick or stainless skillet over medium-high heat. Add the fish and cook for 3-4 minutes per side, until golden and opaque. Transfer to a plate.
3. Start the sauce: Lower the heat to medium. Add butter to the same skillet, then stir in the garlic and cook for about 30 seconds until fragrant.
4. Add the lemon: Stir in broth, lemon juice, lemon zest, red pepper flakes, and capers if using. Simmer for 1-2 minutes until slightly glossy.
5. Finish and serve: Stir in parsley. Return the fish to the skillet or plate it, then spoon the warm lemon butter sauce over each fillet. Serve with lemon slices.
Good to know
- Best served right after cooking while the fish is tender and the sauce is glossy.
- Use fillets of similar thickness for even cooking.
- Fish is safely cooked when it reaches 145°F in the thickest part.
