Ingredients

For the Sea Bass:

• 4 sea bass fillets (6 oz each), skin-on
• 3 tablespoons olive oil
• 4 tablespoons (½ stick) unsalted butter
• 4 cloves garlic, minced
• 1 lemon, zested and juiced
• 2 tablespoons fresh parsley, chopped
• 1 teaspoon sea salt
• ½ teaspoon freshly ground black pepper

For the Creamed Spinach:

• 2 pounds (32 oz) fresh spinach, washed
• 2 tablespoons unsalted butter
• 1 shallot, finely diced
• 2 cloves garlic, minced
• 1 cup heavy cream
• ¼ cup Parmesan cheese, freshly grated
• ⅛ teaspoon freshly grated nutmeg
• Salt and pepper to taste

The star ingredients in our Luscious Lemon-Garlic Sea Bass with Creamed Spinach are high-quality sea bass fillets—look for firm, translucent flesh with a clean ocean scent. Fresh lemon provides both zest and juice for a bright flavor profile, while real butter creates that irresistible golden crust on the fish. For the creamed spinach, baby spinach offers more tender texture, but regular spinach works well too—just remove any tough stems before cooking.

Pro Tips

Achieving restaurant-quality results with your Luscious Lemon-Garlic Sea Bass with Creamed Spinach comes down to mastering a few critical techniques:

First, the secret to perfectly crispy fish skin is starting with thoroughly dry fillets. Pat the sea bass completely dry with paper towels, then let it sit at room temperature for 10-15 minutes before cooking. This prevents the fish from steaming rather than searing. When you place the fish in the pan, press down gently with a spatula for the first 30 seconds to ensure even contact with the hot surface.

Second, don’t rush the spinach preparation. The most common mistake is undercooking the spinach water. After wilting the spinach, press it firmly in a colander to remove excess moisture—this prevents watery creamed spinach. Taking this extra minute makes the difference between silky, luxurious creamed spinach and a watery disappointment.

Finally, master the art of basting. When you add butter to the pan with the fish, tilt the pan slightly to collect the melted butter, then continuously spoon it over the fish. This technique, called butter basting, ensures even cooking and develops extraordinary flavor throughout the fillet, not just on the surface.

Instructions

Step 1: Prepare the Sea Bass

Pat the sea bass fillets completely dry with paper towels—this is essential for achieving a crispy skin. Season both sides generously with salt and pepper, ensuring even coverage. Allow the fish to rest at room temperature for 10-15 minutes to promote even cooking. While waiting, zest and juice your lemon, and finely mince the garlic, keeping them in separate small bowls.

Step 2: Start the Creamed Spinach

Heat a large, deep skillet over medium heat and add 2 tablespoons of butter. Once melted, add the diced shallot and cook until translucent, about 2-3 minutes. Add the garlic and cook for another 30 seconds until fragrant but not browned. Working in batches, add the fresh spinach, stirring constantly until it wilts down. This process transforms a mountain of raw spinach into a manageable amount. Once all spinach is wilted, transfer to a colander and press firmly with the back of a spoon to remove excess water.

Step 3: Cook the Sea Bass

Heat a large stainless steel or cast-iron skillet over medium-high heat. Add olive oil and wait until it’s shimmering hot. Place the sea bass fillets skin-side down in the pan, pressing gently with a spatula for the first 30 seconds to ensure the skin makes even contact with the hot surface. Cook undisturbed for 3-4 minutes until the skin is golden and crispy.

Step 4: Flip and Butter Baste

Add the butter, minced garlic, and lemon zest to the pan alongside the fish. Once the butter melts, carefully flip the fillets and reduce heat to medium. Tilt the pan slightly to pool the butter mixture and spoon it continuously over the fish for another 2-3 minutes until the fish is opaque and flakes easily with a fork. Remove the pan from heat and drizzle with fresh lemon juice.

Step 5: Finish the Creamed Spinach

Return to your second pan and add the drained spinach back to the skillet. Pour in the heavy cream and bring to a gentle simmer over medium-low heat. Stir in the grated Parmesan cheese and nutmeg, allowing the sauce to thicken for 3-5 minutes. Season with salt and pepper to taste, adjusting the consistency with a splash more cream if needed.

Step 6: Serve

Divide the creamed spinach among four warm plates, creating a bed for the fish. Place a sea bass fillet on top of each, skin-side up to maintain crispness. Spoon any remaining lemon-garlic butter from the pan over the fillets and garnish with chopped fresh parsley. Serve immediately while the contrast between the crispy skin and tender fish is at its peak.

Variations

Transform your Luscious Lemon-Garlic Sea Bass with Creamed Spinach with these delicious variations:

Mediterranean Style: Incorporate sun-dried tomatoes, kalamata olives, and crumbled feta into the creamed spinach. Top the finished dish with a sprinkle of toasted pine nuts for added texture. This Mediterranean twist adds bright, briny notes that complement the lemon-garlic sea bass beautifully.

Dairy-Free Version: Create a dairy-free alternative by replacing the butter with olive oil and substituting the heavy cream with full-fat coconut milk in the spinach. Add a tablespoon of nutritional yeast instead of Parmesan for a surprisingly cheesy flavor without the dairy. The coconut milk adds a subtle sweetness that works wonderfully with the lemon-garlic profile.

Herb-Crusted Upgrade: Before cooking, press a mixture of fresh herbs (dill, parsley, and chives), lemon zest, and panko breadcrumbs onto the non-skin side of the fish. This creates a beautiful textural contrast with a herbaceous crust on one side and crispy skin on the other, elevating your lemon-garlic sea bass to a new level of sophistication.

Storage and Serving

Your Luscious Lemon-Garlic Sea Bass with Creamed Spinach is best enjoyed immediately after preparation to maintain the perfect contrast between crispy skin and tender fish. However, if you have leftovers, store the fish and spinach separately in airtight containers in the refrigerator for up to 2 days. When reheating, do so gently—place the fish in a 275°F oven for 10-15 minutes, and warm the creamed spinach in a skillet over low heat with a splash of cream to revive its silky texture.

For an elegant presentation, serve this dish with a simple side of roasted fingerling potatoes seasoned with herbs and a drizzle of extra virgin olive oil. The potatoes’ crispy exterior and creamy interior complement both the fish and spinach beautifully.

This sea bass also pairs wonderfully with a chilled glass of unoaked Chardonnay or Sauvignon Blanc, whose bright acidity cuts through the richness of the dish while complementing the lemon notes. For a complete dinner party experience, start with a light salad dressed in a lemon vinaigrette to introduce the citrus theme that runs throughout the meal.

FAQs

Can I use a different fish for this recipe?
Yes! While sea bass provides a beautiful buttery texture, this lemon-garlic preparation works wonderfully with other white fish like halibut, cod, or even snapper. Adjust cooking times according to thickness—thinner fillets may need only 2-3 minutes per side.

How can I tell when the fish is perfectly cooked?
Sea bass is done when the flesh turns from translucent to opaque and flakes easily when tested with a fork. For precision, the internal temperature should reach 137°F. Avoid overcooking as it quickly dries out the fish.

Can I make the creamed spinach ahead of time?
Yes! The creamed spinach can be made up to 2 days ahead and stored in the refrigerator. Reheat gently on the stovetop with an extra splash of cream to restore its silky texture before serving.

What’s the best substitute for heavy cream in the spinach?
Half-and-half provides a lighter alternative while maintaining creaminess. For dairy-free options, full-fat coconut milk works surprisingly well, adding a subtle sweetness that complements the garlic and spinach.

Why is my sea bass skin not getting crispy?
Three common reasons: the fish wasn’t dried thoroughly before cooking, the pan wasn’t hot enough, or the fish was moved too soon. Ensure your fish is completely dry, your pan is properly heated, and resist the urge to move the fish for at least 3 minutes after placing it skin-side down.
