Ingredients for pan fried cod with lemon butter sauce
Simple ingredients transform into restaurant-quality cod with crispy crust and velvety lemon butter sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Cod Fillets 🐟 | 4 pieces | Skin-on, 6-8 oz each |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into 8 pieces |
| Fresh Lemon Juice 🍋 | ¼ cup | Strained, no pulp |
| Fresh Lemon Zest 🍋 | 1 tbsp | Fine, from 1 lemon |
| All-Purpose Flour 🌾 | ¼ cup | For dredging |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Cloves 🧄 | 2 cloves | Minced, for sauce |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For pan searing |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
| Butter (for basting) 🧈 | 2 tbsp | Melted, for finishing |
The cod is the star—look for fresh, skin-on fillets with a vibrant color and firm texture. Whole Foods or your local fishmonger are best for quality, but grocery stores often carry pre-packaged cod that works fine. If buying frozen, thaw overnight in the fridge—never at room temperature. The butter should be cold and cubed for the sauce, not melted. For the lemon, use freshly squeezed juice—bottled won't have the same brightness. The flour acts as a light crust, so don't skip it even if you're not a fan of heavy breading.
No fresh parsley? Dried parsley at one-third the amount works in a pinch, though fresh is ideal. Short on lemon? Substitute lime juice, but reduce to half the quantity—the flavor profile shifts slightly. The olive oil can be swapped for avocado oil if you prefer a higher smoke point. For extra richness in the sauce, add a pinch of Dijon mustard. If you're serving this with roasted asparagus, season it with salt and pepper before roasting—no need for extra flavor since the cod's sauce will carry through.
The cod stays fresh for 1-2 days in the fridge, but cook it immediately for best texture. Leftover sauce keeps for 3 days in an airtight container, though it's best used fresh. To reheat, warm gently in a saucepan over low heat with a splash of water or lemon juice. The butter cubes for the sauce can be prepped ahead and stored in the freezer for up to 3 months. Garnish with parsley right before serving—it wilts quickly when exposed to heat.

Step-by-step instructions for pan fried cod with lemon butter sauce
Here's the method to achieve a golden crust and tender fillets every time.
Prepare the Cod Fillets for Crispy Skin
Pat the 4 pieces of cod fillets completely dry with paper towels—this is crucial for that crispy crust. I press firmly on each fillet, even between the skin and flesh, to remove all moisture. Season both sides generously with 1.5 teaspoons of sea salt and 0.5 teaspoon of ground black pepper, pressing the spices into the flesh so they adhere well.
Dredge each fillet lightly in 0.25 cup of all-purpose flour, shaking off any excess. The flour creates a delicate crust that crisps beautifully when seared. Let the floured fillets sit on a wire rack for 5 minutes while you prepare the pan—this prevents soggy crusts when cooking.
Sear the Cod in Hot Olive Oil
Heat 1 tablespoon of extra-virgin olive oil in a large skillet over medium-high heat until shimmering. Place the cod fillets skin-side down in the pan and press gently with a spatula for 30 seconds to ensure even contact with the hot oil. This prevents curling and ensures crispy skin.
Cook undisturbed for 3-4 minutes until the skin turns golden brown and crispy, and the edges lift easily from the pan. Flip carefully and cook the flesh side for another 2-3 minutes until opaque throughout. The internal temperature should reach 145°F—use an instant-read thermometer to check the thickest part of each fillet.
Prepare the Lemon Butter Sauce
While the cod cooks, melt 0.5 cup of unsalted butter in a small saucepan over medium-low heat. Add the 2 cloves of minced garlic and cook for 30 seconds until fragrant—don't let it brown or it'll turn bitter. Remove from heat and stir in 0.25 cup of fresh lemon juice and 1 tablespoon of fresh lemon zest. Keep warm until ready to use.
This sauce should be bright and tangy, with the lemon cutting through the richness of the butter. If you prefer a smoother texture, strain out the zest after combining. The acidity from the lemon also helps tenderize the cod slightly as it finishes cooking.
Finish with Melted Butter and Garnish
Transfer the cooked cod fillets to a warm serving platter. Increase the heat under the lemon butter sauce to medium and add the 2 tablespoons of melted butter (for basting). Spoon this over the fillets, letting it melt and baste the top for 30 seconds—this adds extra richness and helps distribute the sauce evenly.
Garnish each fillet with 0.125 cup of chopped fresh parsley and serve immediately. The parsley adds freshness that balances the richness of the butter sauce. The cod should be tender with a crispy skin that contrasts perfectly against the silky sauce.
Pro Tips For Making Pan Fried Cod With Lemon Butter Sauce
- Preheat Pan Properly: Get that pan screaming hot—medium-high to high—before adding butter. I used to rush this, and the butter would foam up like a sad science experiment instead of turning golden. A hot pan seals the cod’s crust faster and keeps it from steaming into mush.
- Pat Cod Dry First: Wrap the fillets in paper towels and press hard—no wet spots. Moisture is the enemy of a crispy crust. I learned this after flipping soggy cod that clung to the pan like a sad, greasy hug.
- Don’t Overcrowd the Pan: Fry one fillet at a time, even if it means two batches. Crowding drops the pan’s temperature, and you’ll end up with greasy, unevenly cooked fish. Trust me, the extra minute waiting is worth it.
- Deglaze with Lemon Early: As soon as you remove the cod, pour in the lemon juice and scrape up those browned bits—now. That’s where all the flavor hides. Skip this, and you’re basically serving butter-flour paste with a side of regret.
Essential equipment for this dish
Skillet Selection
For pan-frying cod, I swear by a 10-inch cast-iron skillet like the Lodge Pre-Seasoned—its weight distributes heat evenly and retains it perfectly for crispy skin. If you prefer something lighter, a stainless steel skillet (like All-Clad Stainless) works too, but monitor heat more closely.
Avoid non-stick pans—they don’t get hot enough for that golden crust. 🔥
Heat Control Tools
A thermometer is non-negotiable. I use the Thermoworks Thermapen ONE to check oil temperature at 375°F—this ensures the cod sears properly without burning. For budget-friendly options, the Meater+ or even a candy thermometer works. Never guess—precise heat control is everything for perfect cod.
Butter Tools
Cold butter cubes are key for the sauce, so I use a microplane to zest lemons and a sharp chef’s knife to dice butter into ½-inch cubes. For melting, a small stainless steel saucepan (like Demeyere) prevents scorching.
Store extra butter cubes in the freezer in a ziplock bag—they’ll keep for months and save prep time.
Garnish Essentials
Fresh parsley is a must, so I keep a small bunch in the fridge and chop it with kitchen shears for quick, even cuts. A fine-mesh strainer helps remove zest pulp if you prefer a smoother sauce.
For plating, a tongs set (like OXO Good Grips) makes transferring fillets effortless without tearing the crispy skin.
Optional Upgrades
For extra crispiness, a wire cooling rack lets excess oil drip away while the cod rests. A small ladle helps baste the sauce evenly over the fillets. If you love garlic, a garlic press speeds up mincing—just don’t overdo it, or the sauce will taste bitter. 💡

Frequently asked questions
Can I use frozen cod for this recipe?
Yes, but thaw it properly first! Place frozen cod fillets in a sealed bag and submerge in cold water for 30-45 minutes (change water halfway). Never thaw at room temperature—it promotes bacterial growth. For best texture, cook the cod immediately after thawing. The skin may not crisp as perfectly as fresh, but it'll still be delicious.
What if my cod skin doesn't get crispy?
This usually happens when the pan isn't hot enough or the fish isn't dry. First, make sure your skillet reaches 375°F—test with a drop of water that sizzles immediately. Pat the cod extra dry with paper towels before cooking. For stubborn cases, press the fillets with a spatula for 10 seconds after placing them in the pan to ensure full contact.
How do I make the lemon butter sauce ahead of time?
Prepare the sauce components separately and store them in airtight containers: melt the butter and cool completely, store lemon juice/zest in the fridge, and keep garlic minced in the freezer. When ready to use, reheat the butter over low heat and combine with fresh lemon juice/zest. For extra flavor, add a pinch of salt and 1 tablespoon of heavy cream at the end. The sauce keeps for 3 days in the fridge.
Can I substitute haddock or halibut for cod?
Haddock and halibut work beautifully with this method—they have similar textures and flavors. For halibut (which is denser), cook for 4-5 minutes per side instead of 3-4. The lemon butter sauce complements both perfectly. Just ensure your fillets are ½-inch thick for even cooking. The crispy skin technique remains the same.
What's the best way to reheat leftovers?
Reheat cod gently to avoid drying it out. Place fillets on a baking sheet and warm in a 300°F oven for 5-7 minutes until just heated through. For the sauce, warm it in a saucepan over low heat with a splash of water or lemon juice to prevent curdling. Never microwave—the texture becomes rubbery. Serve immediately after reheating.
