Ingredients

For the Sea Bass:

1 lb Chilean sea bass fillet (skin-on, if possible)

1 tsp sea salt

1 tsp black pepper

1 tsp Creole seasoning

2 tbsp butter

For the Creamed Spinach:

12 oz fresh spinach leaves

2 tsp minced garlic

1/4 cup heavy whipping cream

1 tbsp butter

1/4 tsp sea salt

1/4 tsp black pepper

For the Lemon Parmesan Sauce:

3 tbsp butter

2 tbsp all-purpose flour

3 tsp minced garlic

1/4 cup chicken broth

1/2 cup heavy whipping cream

3 tbsp grated Parmesan cheese

1/2 tsp garlic powder

1 tsp dried oregano

1/4 tsp black pepper

1/4 tsp sea salt

Zest and juice of 1 lemon

Instructions

  1. Preheat oven to 400°F (200°C).
  2. Pat sea bass fillets dry. Season both sides with salt, pepper, and Creole seasoning.
  3. Heat a cast-iron skillet over medium-high. Melt 2 tbsp butter, then place fish skin-side down. Sear 3–4 minutes until golden. Flip and cook 2 minutes.
  4. Transfer skillet to oven and bake 8–10 minutes, until fish is flaky.
  5. For the spinach: Melt 1 tbsp butter in a pan. Sauté garlic for 1 minute, then add spinach and cook until wilted. Stir in cream, salt, and pepper. Simmer until thickened.
  6. For the sauce: Melt 3 tbsp butter in a saucepan. Whisk in flour, cooking 1–2 minutes. Stir in garlic, then gradually whisk in broth and cream. Add Parmesan, garlic powder, oregano, salt, pepper, lemon juice, and zest. Simmer 3–4 minutes until thickened.
  7. To serve: Place creamed spinach on plates, top with sea bass, and drizzle with lemon Parmesan sauce.

Notes

  • Swap sea bass with halibut or cod for a similar texture.
  • Add a pinch of red pepper flakes to the sauce for heat.
  • Use kale instead of spinach for a heartier green.
  • Make lighter by using half-and-half in place of cream.
  • Pair with roasted potatoes, rice, or crusty bread to soak up the sauce.
