Grilled Sea Bass with Herb Butter tastes rich and clean, with crisp edges, a silky center, and bright lemon-herb aromas. It suits weeknight cooks and dinner-party hosts alike, and you can plate it in about 20 to 25 minutes. I once grilled it in flip-flops while my kid timed me with a kitchen timer.
Why Grilled Sea Bass with Herb Butter Is Worth It
Grilled Sea Bass with Herb Butter gives you restaurant results without fancy techniques. The hot grill kisses the skin until it turns shatter-crisp, while the herb butter melts into a glossy sauce. You get big flavor from simple ingredients.
You also get flexibility. You can swap herbs, change the citrus, and use a grill pan if rain starts. The method stays steady, and the fish stays tender.
Ingredients You Need
- Sea bass fillets, skin-on, 1 to 1.5 inches thick, 6 to 8 ounces each
- Chilean sea bass works, but branzino or black cod also grill well
- Kosher salt and freshly ground black pepper
- I like Diamond Crystal; if you use Morton, use a little less
- Extra-virgin olive oil for brushing
- Lemon, zest and wedges for serving
- Herb butter
- 4 tablespoons unsalted butter, softened
- 1 small garlic clove, minced or 1 teaspoon jarred minced garlic
- 2 tablespoons chopped fresh herbs: parsley, chives, dill, or tarragon
- 1 teaspoon lemon zest
- Pinch of chili flakes or Aleppo pepper, optional
- Pinch of flaky sea salt
- Pantry shortcuts
- Use store-bought garlic-herb compound butter if you need speed
- Swap fresh herbs with 1 teaspoon dried Italian seasoning in a pinch
- Bottled lemon juice works, but fresh lemon tastes brighter
- Sub notes
- No sea bass at the market? Try halibut, snapper, branzino, or trout
- Dairy-free? Use olive oil and a drizzle of good pesto at the end
Equipment
- Gas or charcoal grill, or a grill pan or cast-iron skillet
- Long tongs and a fish spatula
- Paper towels and high-heat oil for the grates
- Instant-read thermometer
- Optional cedar plank, soaked 1 hour
Quick Tips & substitutions
- Dry the fillets very well and oil the skin so it releases from the grates.
- Heat the grill to medium-high, about 425 to 450 F, and clean the grates.
- Lightly score the skin with a few shallow slashes to prevent curling.
- Aim for 125 to 130 F in the thickest part for juicy, flaky fish.
- Slide a thin spatula under the skin and lift with confidence once the skin crisps.
- No outdoor grill? Use a ripping-hot grill pan or cast iron on the stovetop.
- Swap herbs based on what you have: basil and chives in spring, dill and parsley in summer, thyme in fall.
- Use ghee for a nutty butter flavor if you keep it in the pantry.
How to Make Grilled Sea Bass with Herb Butter
Prep Time: 10 minutes
Cook Time: 8 to 10 minutes
Total Time: 20 minutes
- Stir the herb butter: mix softened butter, garlic, chopped herbs, lemon zest, chili flakes, and a pinch of flaky salt. Taste and adjust salt. Spoon onto parchment, roll into a short log, and chill while you heat the grill.
- Heat the grill to medium-high, about 425 to 450 F. Scrub the grates clean, then oil them by rubbing a folded, oiled paper towel with tongs.
- Pat the sea bass dry on all sides. Lightly score the skin with 3 to 4 shallow slashes. Brush the fish with olive oil and season both sides with kosher salt and black pepper.
- Place the fish on the grill skin-side down. Close the lid and cook 4 to 5 minutes until the skin turns crisp and the fish releases when you nudge it.
- Flip with a fish spatula and cook 2 to 4 minutes more, depending on thickness. Check the center with a thermometer and pull at 125 to 130 F. Set a slice of herb butter on each fillet during the last minute so it melts over the top.
- Rest the fish off heat for 2 minutes. Finish with a squeeze of lemon and a sprinkle of fresh herbs. Plate with any melted butter from the resting platter.
Note for stovetop: Heat a grill pan or cast iron over medium-high, oil it lightly, and follow the same timing.
Simple Variations
- Citrus swap: Use lime zest and wedges with cilantro and chives.
- Smoky vibe: Add 1 teaspoon smoked paprika to the herb butter and grill over charcoal.
- Mediterranean twist: Add capers and chopped olives to the butter and finish with cherry tomatoes.
- Chili-lime: Blend softened butter with chili crisp and lime zest, then top with scallions.
Ways to Serve Grilled Sea Bass
- Spoon over garlicky mashed potatoes or lemony couscous.
- Pair with grilled asparagus, blistered green beans, or a crisp fennel salad.
- Serve on toasted ciabatta with arugula for a knife-and-fork sandwich.
- Pour a chilled Sauvignon Blanc, Albariño, or a light pilsner.
Storage
Cool leftovers to room temp for 20 minutes, then refrigerate in a shallow, airtight container for up to 2 days. Reheat gently in a covered skillet over low heat with a spoon of water or extra butter so the fish stays moist. Flake cold leftovers into a salad or tacos for the best texture. Freeze cooked fish only if you must, up to 1 month, and thaw in the fridge before a gentle reheat.
