- 4 fillets (6 oz each) Chilean sea bass fillets
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 4 tbsp unsalted butter
- 2 cloves garlic cloves, minced
- 3 tbsp fresh lemon juice

- Step 1: Pat dry 4 Chilean sea bass fillets (6 oz each) and season both sides with 1 tsp kosher salt and 1/2 tsp black pepper.
