Equipment

Ingredients

  • 1 pound Chilean sea bass fillets
  • 1.5 teaspoons kosher salt
  • 1 teaspoon oregano
  • ½ teaspoon Italian seasoning
  • ¼ teaspoon black pepper
  • ¼ teaspoon red pepper flakes (optional and to taste)
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 medium lemon, zest (zest of 1 lemon)
  • ½ medium lemon, juiced (juice of ½ lemon)
  • 4 cloves garlic, minced
  • lemon slices to top the fillets
  • oregano & parsley to garnish

Instructions

  • Preheat the oven to 400°F. Prepare a baking sheet with parchment paper. Dry off the sea bass fillets very well with paper towels.
  • In a small bowl, combine 1.5 teaspoons of kosher salt, 1 teaspoon of oregano, ½ teaspoon of Italian seasoning, ¼ teaspoon of black pepper, and ¼ teaspoon of red pepper flakes. Sprinkle the seasoning mixture all over the sea bass fillets, and make sure everything is covered.
  • In another small bowl, melt butter. Add minced garlic, lemon juice, lemon zest, and olive oil and mix to combine. Pour the butter mixture over top of the sea bass fillets.
  • Transfer the Chilean sea bass to the prepared baking sheet. Place lemon slices over top of the fillets. Bake for 12-15 minutes, until the internal temperature reaches 145°F and the fish can be flaked with a fork. Set aside for a few minutes to let the fish rest after cooking.
  • Garnish with fresh parsley, oregano, and lemon slices for garnish. Spoon any butter sauce overtop of the fish. Enjoy!
  • Store leftovers in an airtight container in the fridge for 2-3 days. Reheat gently in the microwave or oven. Do not freeze.

Notes

  • Thaw the sea bass completely before cooking if frozen. 
  • Make sure to dry off the fillets very well to soak up any excess moisture.
  • Use parchment paper for easy cleanup.
  • Don't overcook the fish, or it will become dry and lose flavor. A meat thermometer is the best way to ensure it's cooked to perfection.
  • Let the fish rest for a few minutes after cooking to allow the fish to hold onto some of the moisture and the flavor.
  • Feel free to add or omit seasonings, lemon juice, and herbs as you see fit.
  • For dairy free, swap the butter with olive oil.
