Ingredients
- 4 fillets (6 oz each) sea bass fillets
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 4 tbsp unsalted butter
- 3 sprigs fresh thyme sprigs
- 2 tbsp lemon juice
- 1 tsp lemon zest
Instructions
- Step 1: Pat dry 4 sea bass fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering.
- Step 2: Place the fillets skin-side down in the skillet and cook for 4-5 minutes until the skin is crisp and golden. Flip the fillets carefully and cook for another 2-3 minutes until the fish is opaque and flakes easily.

- Step 4: Remove the pan from heat and stir in 2 tbsp lemon juice and 1 tsp lemon zest. Spoon the lemon-thyme butter sauce over the fillets before serving.
Frequently asked questions
How long does Pan-Seared Sea Bass with Lemon and Thyme Butter take to make?
Total time is about 20 minutes (10 min prep + 10 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.
How do I store leftover Pan-Seared Sea Bass with Lemon and Thyme Butter?
Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep salt from drying out.
Can I substitute ingredients in Pan-Seared Sea Bass with Lemon and Thyme Butter?
Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.
How do I scale Pan-Seared Sea Bass with Lemon and Thyme Butter for a different number of people?
