Cod Tips
Choosing fresh, high-quality cod fillets makes a huge difference in this recipe. Look for thick, firm fillets with a white and shiny appearance. Fresh cod should smell like the ocean – clean but not overly fishy. When you bring it home, pat the fillets dry to remove excess moisture; this step is crucial for a crispy sear. If frozen, thaw the cod in the refrigerator overnight and dry it thoroughly before cooking. Using fresh cod ensures tender flakes and a mild flavor that pairs beautifully with the lemon butter sauce.
Options for Substitutions
- Swap cod fillets for haddock, tilapia, or halibut for a similar texture.
- Use vegetable broth or white wine instead of chicken broth for dietary preferences.
- Replace all-purpose flour with gluten-free flour or almond flour for gluten-free needs.
- Substitute olive oil with avocado oil or sunflower oil.
- Use dairy-free butter alternatives like margarine or plant-based butter for a vegan twist.
- Swap fresh parsley with fresh dill or basil for a different herb flavor.
Watch Out for These Mistakes
One of the biggest pitfalls is overcooking the cod. Fish cooks quickly, and even a minute or two too long can make it dry and tough. Keep an eye on the fillets while searing—once they’re golden and flake easily, it’s time to remove them from the pan.
Another mistake is skipping the step of patting the fish dry. Moisture on the surface can prevent browning, leaving you with a soggy coating rather than a crisp one. Make sure to use paper towels and gently press the dry surface before seasoning.
When making the pan sauce, be careful not to add the garlic too early or cook it for too long. Garlic burns quickly and can become bitter. Add it last, cook just until fragrant (about 30 seconds), then immediately add broth and lemon juice to dilute the heat.
Finally, don’t forget to taste and adjust seasoning after adding the capers and salt to the sauce. Capers add a salty tang, so you may need less salt than usual.
What to Serve With One Pan Lemon Butter Cod Fillet?

Roasted baby potatoes or creamy mashed potatoes add a comforting touch. For a lighter side, serve it with sautéed green beans or a fresh mixed greens salad tossed with a lemon vinaigrette. Crusty bread also shines here, especially for dipping.

Ingredients
- 4 (6 oz) cod fillets
- 1 tsp kosher salt, divided
- 1/2 tsp black pepper
- 1/3 cup all-purpose flour
- 3 tbsp olive oil
- 4 tbsp unsalted butter, divided
- 3 cloves garlic, minced
- 1/2 cup low-sodium chicken broth
- Juice of 1 large lemon (about 3 tbsp)
- 1 tbsp capers, drained
- 2 tbsp fresh parsley, chopped
- Lemon slices, for garnish
Step-by-Step Instructions
Step 1: Prepare the Cod
Start by patting the cod fillets dry with paper towels. This is important to help the flour stick and to get a nice sear. Season the fillets with half a teaspoon of kosher salt and the black pepper on both sides. Lightly dredge each fillet in the all-purpose flour, shaking off any extra to prevent a thick coating.
Step 2: Sear the Fish
Heat the olive oil and 2 tablespoons of butter in a large skillet over medium-high heat. Wait until the butter is foamy and hot. Gently place the cod fillets in the skillet. Cook for 3 to 4 minutes on each side until golden brown and the fish flakes easily with a fork. The internal temperature should reach 145°F. Once cooked, transfer the fillets to a plate and tent loosely with foil to keep warm.
Step 3: Make the Pan Sauce
Reduce the heat to medium. To the same skillet, add the remaining 2 tablespoons of butter. When the butter begins to melt, add the minced garlic and cook for just 30 seconds until fragrant. Pour in the chicken broth and lemon juice, scraping up the browned bits from the bottom of the pan. Let the sauce simmer for 3 to 4 minutes until it reduces slightly.
Step 4: Finish the Sauce and Serve
Stir in the drained capers and the remaining half teaspoon of salt into the sauce. Return the cod fillets to the skillet and spoon the sauce over them to warm through and absorb the flavors. Sprinkle with fresh chopped parsley and garnish with lemon slices. Serve the fish immediately with your choice of rice, potatoes, or crusty bread.
