How to Make Baked Lemon Butter Sea Bass Fillet
For the Sea Bass Fillet:
- Preheat oven to 400°F (200°C). While the oven heats, line a baking dish with foil or parchment paper to ensure easy cleanup and prevent sticking.
- Season fillets by gently patting each sea bass fillet dry with paper towels, then sprinkle salt and freshly ground black pepper evenly over the flesh and skin sides.
For the Lemon Butter Sauce:
- Melt butter in a small saucepan over medium heat, stirring occasionally until fully melted and slightly bubbling, about 1 to 2 minutes for a smooth sauce base.
- Add garlic and cook over medium heat, stirring constantly until fragrant and lightly golden around the edges, about 30 seconds to 1 minute.
- Stir in lemon juice and zest, whisking continuously until the sauce turns smooth, bright yellow, and beautifully tangy, about 30 seconds for maximum citrus infusion.
- Fold in parsley off heat to preserve its fresh green color, stirring gently until chopped parsley is evenly distributed throughout the lemon butter sauce.
To Bake and Serve:
- Arrange fillets skin-side down in the prepared baking dish, spacing them evenly so hot air circulates and ensures uniform, flaky cooking.
- Pour sauce over the arranged sea bass fillets, using about half of the lemon butter mixture now and reserving the remainder for a finishing drizzle.
- Bake fish in the preheated 400°F oven for 12 to 15 minutes, until the flesh is opaque, flakes easily, and reaches 135°F internal temperature.
- Garnish & serve by spooning the reserved butter sauce over hot fillets, then garnish with extra lemon slices and a sprinkle of fresh parsley for color.
Optional: Serve with crusty bread for dipping into any leftover lemon butter.

Baked Lemon Butter Sea Bass Fillet Recipe FAQs
How do I know if my sea bass fillets are fresh and ready to cook?
Look for fillets that have firm flesh, a mild ocean scent (not fishy), and moist, translucent skin without any dark spots or discoloration. Fresh sea bass should bounce back slightly when pressed gently.
What’s the best way to store leftover Baked Lemon Butter Sea Bass Fillet?
Absolutely keep leftovers in an airtight container, preferably with some of the lemon butter sauce to lock in moisture. Store in the fridge for up to 3 to 4 days for the best flavor and texture.
Can I freeze the baked sea bass fillets? If yes, how?
Very much yes! Wrap each cooled fillet tightly in plastic wrap, then cover with aluminum foil to prevent freezer burn. Label and freeze for up to 3 months. To thaw, place the wrapped fillets in the fridge overnight, then gently reheat in a 350°F oven for 10–15 minutes to preserve their flaky texture.
What should I do if the fish turns out dry after baking?
This happens if it’s overcooked or the fillets are too thin. Next time, reduce baking time slightly and ensure an internal temperature of about 135°F. Also, serve immediately with reserved lemon butter sauce to add moisture back to the fish. Using thicker fillets helps keep that tender, juicy bite!
Is this recipe safe for pets or people with allergies?
This recipe features common allergens like butter and fish. It’s best not to share with pets due to seasoning and lemon, which can be harmful. For those allergic to dairy, consider substituting butter with olive oil or a vegan butter alternative, and always avoid cross-contamination during prep.
