- 4 sea bass fillets (skin on or off, as preferred): Fresh, firm fillets are key for that flaky texture and mild flavor.
- 2 tablespoons olive oil: Adds a subtle fruity richness and helps crisp the fish nicely in the oven.
- 1 lemon, sliced into rounds: Provides zesty brightness and a touch of acidity to balance the fish.
- 4 sprigs fresh thyme (or 1 teaspoon dried thyme): Offers an earthy, fragrant note that complements the sea bass beautifully.
- Salt and pepper, to taste: Enhances the natural flavors with essential seasoning.
- 2 cloves garlic, minced (optional): Adds a gentle aromatic punch if you want extra depth.
- Fresh parsley, chopped (for garnish): Brings a fresh, green pop of color and mild herbal flavor at the end.
How to Make Lemon and Thyme Roasted Sea Bass Recipe
Step 1: Preheat the Oven and Prepare the Baking Dish
Set your oven to 400°F (200°C) so it’s perfectly hot when your sea bass is ready to go in. While it heats, lightly grease a baking dish with a bit of olive oil; this helps the fish cook evenly and prevents sticking, giving you a lovely caramelized edge.
Step 2: Season the Sea Bass Fillets
Pat the sea bass fillets dry with paper towels. This step is crucial because it ensures the olive oil and seasonings stick well, helping the fish to crisp up. Rub both sides with olive oil, then generously sprinkle salt and pepper. If you love garlic, mix the minced cloves with the oil before applying to infuse the fish with a mild garlicky note.
Step 3: Arrange the Fillets in the Baking Dish
Place the seasoned fillets skin side down if they have skin, or simply flat side down if not. Layer the lemon slices on top and tuck the thyme sprigs around and on the fillets. This simple arrangement not only looks inviting but allows the lemon and thyme to release their flavors gradually, soaking into the fish while roasting.
Step 4: Roast the Sea Bass
Pop the baking dish into your hot oven for about 12 to 15 minutes, depending on thickness. You’ll know it’s done when the fish flakes easily with a fork and has turned opaque. Keep an eye so it doesn’t overcook — you want tender, moist fillets, not dry ones.
Step 5: Garnish and Serve
Once out of the oven, sprinkle fresh chopped parsley over the fish for a burst of color and fresh herb flavor. Serve hot directly from the baking dish or carefully transfer to plates for a beautiful presentation.

Garnishes
Fresh parsley is a classic, but you might also try some thin lemon zest curls to intensify the citrus aroma. A drizzle of extra virgin olive oil or a light sprinkle of flaky sea salt just before serving can add another layer of texture and flavor. These small touches make the dish feel special and restaurant-worthy.
Side Dishes
This Lemon and Thyme Roasted Sea Bass Recipe pairs wonderfully with many side options. Consider serving it alongside roasted baby potatoes tossed in garlic and rosemary, or a bright and crunchy arugula salad with shaved fennel. Steamed asparagus or sautéed green beans with almonds also complement the fish’s delicate profile perfectly.
Creative Ways to Present
For a crowd-pleasing presentation, arrange the individual fillets on a large platter layered with extra lemon slices and thyme sprigs. You can also place the fish atop a bed of fluffy couscous or creamy risotto to add height and elegance. Wrapping the fillets in parchment paper with lemon and thyme before roasting not only locks in moisture but creates a charming package for each plate.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, place them in an airtight container and refrigerate promptly. They should stay fresh for up to 2 days. Keep the fish fillets separated from wet lemon slices if you want to avoid the texture becoming mushy.
Freezing
Freezing cooked sea bass is possible, but it’s best done if you plan to eat it within 1 month for optimum flavor and texture. Wrap portions tightly in plastic wrap and then foil to prevent freezer burn. Thaw overnight in the fridge before reheating gently.
Reheating
To reheat, avoid the microwave if possible as it can dry out the delicate fish. Instead, warm gently in a low oven (around 275°F or 135°C) for about 10 minutes, covered loosely with foil. This keeps the sea bass moist and flaky.
FAQs
Can I use dried thyme instead of fresh in the Lemon and Thyme Roasted Sea Bass Recipe?
Yes, dried thyme works well here. Use about 1 teaspoon of dried thyme in place of the fresh sprigs. It won’t be quite as vibrant but still delivers that lovely herbal flavor.
Is it necessary to keep the skin on the sea bass fillets?
Keeping the skin on helps the fillets hold together better during cooking and adds a delightful crisp texture if cooked properly. However, if you prefer skinless, that’s perfectly fine and still delicious.
Can I prepare this Lemon and Thyme Roasted Sea Bass Recipe ahead of time?
You can prep the seasoning and arrange everything in your baking dish ahead of time, but it’s best to roast the fish just before serving to ensure freshness and optimal texture.
What sides are best with Lemon and Thyme Roasted Sea Bass Recipe?
Light, fresh sides like steamed vegetables, salads, or simple roasted potatoes complement the fish without overwhelming the delicate flavors.
Can I substitute lemon with another citrus?
Absolutely! Lime or orange slices can bring an interesting twist. Just keep in mind the flavor profile will shift slightly, so adjust seasoning accordingly.
