Introduction
Few dishes strike the perfect balance between elegance and simplicity quite like pan-seared cod with a luscious lemon butter sauce. This recipe transforms humble, flaky white fish into a restaurant-quality meal that comes together in under 20 minutes.
The magic lies in the textural contrast: a delicate, golden-brown crust giving way to tender, moist flesh, all enveloped in a rich, tangy, and aromatic butter sauce. With just a handful of fresh ingredients and one skillet, you can create a dish that feels special enough for a dinner party yet is quick and easy enough for a busy weeknight.
Ingredients
For the Cod:
· 4 cod fillets (150-200g each)
· Salt and pepper, to taste
· ½ cup all-purpose flour (for coating)
· 2 tbsp olive oil
· 1 tbsp unsalted butter
For the Lemon Butter Sauce:
· 3 tbsp unsalted butter
· 2 cloves garlic, minced
· Juice of 1 lemon (about 3 tbsp)
· Zest of 1 lemon (optional, for extra brightness)
· ¼ cup chicken or vegetable broth (optional, for a thinner sauce)
· 2 tbsp fresh parsley, chopped
· Salt and pepper, to taste
Instructions
STEP 1: PREPARE THE COD
Pat the cod fillets dry using paper towels to remove excess moisture. This is a crucial step to ensure a nice, golden sear. Season both sides generously with salt and pepper.
Lightly coat each fillet in flour, shaking off any excess—this thin layer is the secret to creating that crispy, flavorful crust.
STEP 2: COOK THE COD
In a large non-stick skillet, heat the olive oil and 1 tablespoon of butter over medium-high heat. Once the butter is melted and sizzling, carefully lay the cod fillets in the pan. Sear for 3–4 minutes until the bottom turns deep golden brown. Gently flip and cook for another 2–3 minutes, depending on the thickness of your fillets.
The cod is perfectly cooked when it flakes easily with a fork and reaches an internal temperature of 60°C (140°F). Transfer the cooked fillets to a plate and loosely cover with foil to keep them warm while you make the sauce.
STEP 3: MAKE THE LEMON BUTTER SAUCE
Reduce the heat to medium and add the remaining 3 tablespoons of butter to the same pan.
Once it has melted, add the minced garlic and sauté for about 30 seconds until fragrant, stirring constantly to prevent burning. Pour in the lemon juice, using a wooden spoon to scrape up all the delicious browned bits (fond) from the bottom of the pan—this is where the flavor is.
If you prefer a lighter, more abundant sauce, stir in the chicken or vegetable broth and let it simmer for a minute. Finish by stirring in the lemon zest (if using) and fresh chopped parsley. Taste and season with salt and pepper as needed.
STEP 4: SERVE & ENJOY
Return the cod fillets to the pan, spooning the luxurious sauce over them. Let them warm through and absorb the flavors for about 30 seconds.
Transfer the fillets to serving plates and generously drizzle any remaining sauce from the pan on top. Serve immediately with your favorite sides, such as roasted vegetables, creamy mashed potatoes, or a fresh green salad.
How to Make
Creating this dish is a straightforward process that relies on a few key techniques. Start by patting your cod fillets completely dry; moisture is the enemy of a good sear. A light dusting of flour on the seasoned fish provides a thin barrier that crisps up beautifully in the hot pan.
When you add the fish to the skillet with the oil and butter, listen for that satisfying sizzle—if it doesn’t sizzle, your pan isn’t hot enough. Resist the urge to move the fish; let it sit and develop that golden crust. After flipping, the fish cooks quickly, so keep an eye on it.
Once the fish is resting, the sauce comes together in the same pan, leveraging the leftover fond for maximum flavor. The garlic only needs a brief moment in the hot butter to become aromatic, and the lemon juice brightens everything up. A final swirl of butter and fresh parsley creates a silky, vibrant sauce that perfectly coats the delicate fish.
Variations
· Herb-Infused: Swap the parsley for other fresh herbs like chopped dill, chives, or tarragon to change the flavor profile.
· Capers & Olives: For a briny twist, add a tablespoon of capers and a handful of sliced Kalamata olives to the sauce along with the lemon juice.
· Spicy Kick: Add a pinch of red pepper flakes along with the garlic for a subtle heat that complements the buttery sauce.
· Wine Sauce: Replace the chicken broth with dry white wine for a more sophisticated, slightly acidic sauce. Let it simmer for a minute longer to cook off the alcohol.
· Parmesan Crust: After flouring the cod, dip the top side in a mixture of grated Parmesan cheese and panko breadcrumbs before searing for an extra crunchy, cheesy crust.
· Different Fish: This recipe and sauce work wonderfully with other firm white fish such as halibut, sea bass, haddock, or tilapia. Adjust cooking times based on thickness.
Tips
· Dry is Key: Use paper towels to thoroughly dry the fish before seasoning. This is non-negotiable for a good sear.
· Don’t Overcrowd the Pan: Cook the fish in batches if your skillet isn’t large enough to accommodate all fillets with space between them. Overcrowding lowers the pan’s temperature and steams the fish instead of searing it.
· Perfect Doneness: Fish continues to cook slightly after you remove it from the pan due to residual heat. To avoid dry cod, remove it from the skillet just before it’s completely done, or when it reaches 60°C (140°F) internally.
· Use Fresh Lemon: Bottled lemon juice lacks the bright, fresh flavor needed for this sauce. Always opt for freshly squeezed lemon juice and fresh lemon zest.
· Low Heat for Garlic: Garlic burns quickly and turns bitter. Always add it to the pan after you’ve lowered the heat and stir it immediately.
