These fish fillets cook evenly and absorb the lemon butter sauce beautifully. Whether you use fresh or frozen fish, just make sure it’s fully thawed before cooking to ensure even searing.
Ingredients for Simple Fish Fillets with Lemon Butter
Here’s what you’ll need:
For the Fish:
- 4 fish fillets (about 6 oz each)
- Salt and pepper to taste
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 tablespoon fresh parsley (chopped)
For the Lemon Butter Sauce:
- 3 tablespoons unsalted butter
- 3 garlic cloves (minced)
- Juice of 1 large lemon
- 1 teaspoon lemon zest
- Optional: 1 tablespoon white wine or vegetable broth

Step-by-Step Instructions:
1. Prep the Fish
Pat the fillets dry with a paper towel to remove any excess moisture. This helps them sear better. Season both sides with salt, pepper, and garlic powder.
2. Sear the Fillets
In a large non-stick skillet, heat olive oil over medium-high heat. Add the fish fillets and cook for 3–4 minutes per side, depending on thickness. The fish should be golden brown and flaky.
Remove the fillets from the pan and place them on a plate. Tent with foil to keep warm.
3. Make the Lemon Butter Sauce
In the same skillet, reduce heat to medium. Add butter and minced garlic. Sauté until fragrant (about 1 minute). Add lemon juice, lemon zest, and optional white wine or broth. Stir continuously until the sauce slightly thickens (2–3 minutes).
4. Combine and Serve
Return the fish fillets to the skillet and spoon the lemon butter sauce over them. Cook for another minute so the flavors can meld. Sprinkle with chopped parsley and serve immediately.
