This elegant sea bass dish is one of my go to weeknight dinners because it comes together in under an hour and feels surprisingly restaurant quality. The delicate fish pairs beautifully with buttery roasted celery and a bright lemon sauce that really lets the natural flavors shine through. Sea bass is packed with omega 3 fatty acids, which are wonderful for heart health, and the whole meal is light yet satisfying. What I love most is how simple it truly is to make, despite tasting like you spent all day in the kitchen. Fresh thyme and garlic round out the flavors perfectly, creating something I'm genuinely proud to serve to family and friends.

Instructions
- 1
Preheat your oven to 400°F. Pat the sea bass fillets dry with paper towels and season both sides generously with sea salt and black pepper.
Tip: Drying the fish ensures a crispier skin when roasted.
- 2
Heat 1 tablespoon of butter and the olive oil in a large oven-safe skillet over medium-high heat. Once shimmering, arrange the celery batons in a single layer and roast for 8-10 minutes, stirring halfway through, until they develop light golden color at the edges.
Tip: Don't overcrowd the pan; let the celery caramelize for better flavor.
- 3
Push the celery to the sides of the skillet and add the sliced garlic and minced shallot to the center. Cook for 1-2 minutes until fragrant, then add the white wine and bring to a gentle simmer.
Tip: The wine adds acidity that balances the richness of the butter sauce.
- 4
Nestle the sea bass fillets skin-side up among the celery, pour the lemon juice over the fish, and top each fillet with the remaining thyme sprigs.
Tip: Position fillets skin-side up to help maintain their delicate texture during roasting.
- 5
Transfer the skillet to the preheated oven and roast for 12-15 minutes, until the fish is opaque and flakes easily with a fork.
Tip: Fish cooks quickly; check for doneness at 12 minutes to avoid overcooking.
- 6
Remove from the oven and carefully whisk in the remaining 3 tablespoons of cold butter, one piece at a time, until the sauce becomes creamy and emulsified.
Tip: Adding cold butter at the end creates a silky sauce without breaking it.
- 7
Taste the sauce and adjust seasoning with additional salt and pepper if needed. Sprinkle the lemon zest over the dish just before serving.
Tip: Fresh lemon zest brightens the final dish with a pop of citrus aroma.
