- 3 cloves of garlic, minced: Garlic brings a savory depth and richness when combined with olive oil.
- 1/4 cup olive oil: A good quality olive oil helps keep the fish moist and enhances its natural flavors.
- Salt and freshly ground black pepper: Essential seasonings that elevate every bite without overpowering.
- 1/4 cup white wine (optional): Adds an elegant acidity that balances the buttery and citrus components.

How to Make Lemon and Thyme Roasted Sea Bass Recipe
Step 1: Prepare Your Oven and Fish
First things first, preheat your oven to 400°F (200°C). This temperature is perfect for roasting the sea bass evenly, allowing the skin to crisp slightly and the flesh to become tender and flaky. While the oven heats, rinse each fillet under cold water and gently pat them dry with paper towels. Dry fish helps achieve that ideal roast without steaming.
Step 2: Create the Garlic Olive Oil Mixture
In a small bowl, mix the minced garlic with the olive oil. This simple combination will coat the fish, infusing it with subtle garlic flavor that pairs wonderfully with the herbs and lemon. Make sure the garlic is finely minced so that its flavor disperses evenly without becoming overpowering.
Step 3: Season and Arrange the Sea Bass
Lay the fillets skin-side down on a parchment-lined baking sheet to prevent sticking and ensure easy cleanup. Lightly season each fillet with salt and freshly ground black pepper. Then, brush the garlic and olive oil mixture over the top of each piece, making sure every inch is coated. This step is key to locking in moisture and flavor during roasting.
Step 4: Add Lemons and Thyme
Place thin slices of lemon directly on top of the fish. These slices release aromatic oils and juices as the fish cooks, making every bite bursting with fresh citrus notes. Nestle the sprigs of thyme alongside and on top of the fillets to infuse a fragrant herbal aroma throughout the cooking process.
Step 5: Pour Wine and Dot Butter
If using white wine, pour it gently over the fillets to introduce a refined acidity that perfectly balances the richness of the butter and olive oil. Dot each fillet with small pieces of butter to melt over during roasting, adding silkiness and depth to this vibrant dish.
Step 6: Roast to Perfection
Place the baking sheet in the oven and roast for 15 to 18 minutes. You’ll know the fish is done when it turns opaque and flakes easily with a fork. The lemon and thyme will have melded into the fish and butter, creating an irresistible aroma that will fill your kitchen.
Step 7: Rest and Garnish
Once out of the oven, let the sea bass rest for a few minutes. This helps the juices settle so every bite is juicy and tender. Finish by sprinkling fresh thyme leaves on top for a pop of color and fresh herbal flavor that complements the rich, roasted fish.

Garnishes
Simple garnishes elevate this elegant dish beautifully. Consider adding a few extra lemon zest curls or a sprinkle of finely chopped fresh parsley for freshness and a burst of color. The lemon and thyme leaves used as garnish not only look inviting but add a final aromatic touch that tempts your senses before the first bite.
Side Dishes
Lemon and Thyme Roasted Sea Bass Recipe is wonderfully versatile when it comes to sides. It pairs superbly with light, crisp vegetables such as roasted asparagus or sautéed green beans. For a heartier meal, serve alongside buttery mashed potatoes or a fragrant herb rice pilaf. A crisp salad with a citrus vinaigrette will also balance the dish perfectly.
Creative Ways to Present
If you’re hosting guests or want to impress, serve the roasted sea bass on a beautiful rustic wooden board or individual ceramic plates with lemon slices and thyme sprigs artfully arranged. Drizzle any pan juices over the top for a gorgeous, glossy finish. For a modern twist, place the fish atop a bed of lemon-infused quinoa or alongside colorful vegetable ribbons.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftovers from your Lemon and Thyme Roasted Sea Bass Recipe, store them in an airtight container in the refrigerator. They will stay fresh for up to two days, making it easy to enjoy a quick, flavorful meal the next day.
Freezing
While fresh sea bass is best enjoyed right after cooking, you can freeze leftovers by wrapping them tightly in plastic wrap and placing them in a freezer-safe container. Use within one month for best quality. Keep in mind that the texture may slightly change after freezing and thawing.
Reheating
To reheat leftovers without drying out the fish, warm gently in a low oven around 275°F (135°C) for about 10 minutes, or until heated through. Alternatively, you can reheat in a microwave on low power in short bursts, covered with a damp paper towel to retain moisture.
FAQs
Can I use frozen sea bass fillets for this recipe?
Yes, you can use frozen sea bass fillets, but be sure to thaw them fully and pat dry before cooking to avoid excess moisture. This helps achieve that perfect roast and crispy edges.
Is white wine necessary in this Lemon and Thyme Roasted Sea Bass Recipe?
White wine is optional, but it adds a lovely acidity and complexity. If you prefer not to use alcohol, simply omit it or substitute with a splash of vegetable broth or lemon juice for brightness.
Can I substitute other herbs for thyme?
Thyme’s subtle earthiness pairs perfectly with sea bass, but you can experiment with rosemary or tarragon for a different flavor profile. Just use fresh herbs to keep the dish light and aromatic.
How do I know when the sea bass is cooked properly?
The fish is done when it becomes opaque all the way through and flakes easily with a fork. Overcooking can make it dry, so watch carefully especially if your fillets are on the thinner side.
Can this recipe be doubled for a larger group?
Absolutely! Simply increase the quantities proportionally and use a larger baking sheet or multiple trays to ensure even cooking. Just keep an eye on the cooking time as it may vary slightly depending on your oven.
