• 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

Directions

1. Pat the sea bass fillets dry with paper towels. Season both sides with salt, pepper, and Creole seasoning.

2. Heat a cast-iron skillet over medium-high. Melt 2 tbsp butter until bubbling, then place the fish skin-side down. Sear 3–4 minutes until golden. Flip and cook 2 more minutes.

3. Transfer the skillet to a 400°F (200°C) oven and bake 8–10 minutes, until flaky.

4. For the creamed spinach, melt 1 tbsp butter in a pan. Sauté garlic for 1 minute. Add spinach and cook until wilted. Stir in cream, salt, and pepper, simmering until thickened.

5. For the sauce, melt 3 tbsp butter in a saucepan. Whisk in flour and cook 1–2 minutes. Stir in garlic, then slowly whisk in broth and cream. Add Parmesan, garlic powder, oregano, pepper, salt, lemon juice, and zest. Simmer 3–4 minutes until thickened.

6. To assemble, place creamed spinach on plates, top with sea bass, and drizzle with lemon Parmesan sauce.

Variations

• Swap sea bass with halibut or cod for a similar flaky texture.

• Add a pinch of crushed red pepper to the sauce for a spicy kick.

• Use kale instead of spinach for a heartier green side.

• Make it lighter by substituting half-and-half for heavy cream.

Storage/Reheating

Refrigerate leftovers in an airtight container for up to 2 days. To reheat, warm the fish in the oven at 300°F until just heated through, and gently reheat the sauce and spinach on the stovetop over low heat. Avoid microwaving the fish to preserve its texture.

FAQs

Can I use frozen sea bass for this recipe?

Yes, but make sure it’s fully thawed and patted dry to achieve a good sear.

What can I use instead of heavy cream?

Half-and-half or whole milk can work, but the sauce will be less rich and creamy.

How do I know when the sea bass is cooked?

The fish should flake easily with a fork and reach an internal temperature of 145°F (63°C).

Can I make the sauce ahead of time?

Yes, prepare it up to a day in advance and reheat gently before serving.

Is there a dairy-free option for this dish?

You can substitute coconut cream for the spinach and sauce, and use a plant-based butter alternative.

What skillet works best for searing?

A cast-iron skillet is ideal because it retains heat well and helps form a crisp crust.

Can I grill the sea bass instead of searing and baking?

Yes, grill over medium heat for about 4–5 minutes per side, then serve with the spinach and sauce.

Can I make the creamed spinach on its own?

Absolutely, it works as a versatile side dish for steak, chicken, or pasta.

What wine pairs well with this dish?

A crisp Chardonnay or Sauvignon Blanc complements the lemony, buttery flavors.

How do I prevent the sauce from curdling?

Keep the heat moderate and whisk continuously while adding cream to avoid separation.
