This is one of my favorite weeknight dinners because it feels fancy but comes together in under an hour. Grilled sea bass is naturally lean and packed with omega 3 fatty acids that are wonderful for your heart, and the delicate fish pairs beautifully with bright lemon and tender leeks. What I love most is how simple it truly is, just a few quality ingredients and some gentle heat on the grill. The lemon butter sauce is pure magic, turning something humble into something that tastes like it came from a restaurant kitchen. Your guests will be amazed, and you'll barely break a sweat.

Instructions
- 1
Preheat grill to medium-high heat (around 400°F). Pat sea bass fillets dry with paper towels and lightly coat both sides with olive oil. Season generously with salt and pepper.
Tip: Dry fish ensures better browning and prevents sticking to the grill grates.

Heat 2 tablespoons of butter in a large skillet over medium heat. Add sliced leeks and sauté for 5-7 minutes, stirring occasionally, until they begin to soften and turn golden. Add minced garlic and cook for 1 minute more until fragrant.
Tip: Don't rush the leeks; slow cooking brings out their natural sweetness.
- 3
Pour white wine into the skillet with leeks, scraping up any browned bits from the bottom. Reduce heat to low and simmer for 3-4 minutes until the wine reduces slightly. Set aside and keep warm.
- 4
Place sea bass fillets skin-side down on the preheated grill. Grill for 5-6 minutes without moving, allowing the skin to crisp and char slightly.
Tip: Resist the urge to flip too early; let the skin develop a protective crust.
- 5
Carefully flip the fillets and grill for another 3-4 minutes on the flesh side until the fish is opaque and flakes easily with a fork.
Tip: The total cooking time depends on fillet thickness; aim for an internal temperature of 145°F.
- 6
Transfer grilled sea bass to a serving platter. Stir remaining 2 tablespoons of butter and fresh lemon juice into the warm leek mixture. Pour the leek and butter sauce around the fish.
Tip: The residual heat will melt the butter into a silky sauce.
- 7
Garnish each fillet with fresh thyme sprigs, lemon zest, and chopped parsley. Serve immediately while hot.
Tip: The fresh herbs add brightness and aroma to complement the delicate fish.
