Step‑by‑Step Instructions for Lemon Garlic Butter Cod
Step 1: Prepare the Cod
Begin by patting the cod fillets dry with a paper towel to ensure a great sear. Season both sides liberally with kosher salt and freshly cracked pepper, enhancing the overall flavor of the Lemon Garlic Butter Cod. Make sure to allow the fish to rest while you prepare your cooking station, which will help develop a flavorful crust.
Step 2: Heat the Skillet
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat until it shimmers. This oil will help to sear the cod evenly and prevent the butter from burning later. Once the oil is hot, carefully add the seasoned fillets to the skillet; they should sizzle upon contact, signaling that you’re on the right track to achieving that perfect golden color.
Step 3: Sear the Cod
Cook the cod fillets for 2-3 minutes on one side without moving them, allowing a beautiful crust to form. Afterward, gently flip the fillets using a fish spatula and cook for another 2-3 minutes until they are lightly golden but still slightly underdone. You’ll know they’re ready when they just start to flake at the edges. Remove and let them rest on a plate.
Step 4: Melt the Butter
Lower the skillet heat to medium and add 3 tablespoons of unsalted butter to the same pan, letting it melt gently. This butter will create a luscious sauce to drape over the cod. As it melts, be sure to scrape any flavorful bits left from searing the fish, as they will add rich depth to the sauce.
Step 5: Add Garlic
Once the butter is completely melted, add the minced garlic to the skillet. Stir it gently and cook for about 30 seconds, until fragrant, being careful not to let it brown. The aroma at this stage will truly enhance your Lemon Garlic Butter Cod, laying the foundation for a delicious sauce that complements the fish beautifully.
Step 6: Incorporate Lemon Juice and Zest
Stir in the fresh lemon juice and lemon zest, mixing to combine. Allow the sauce to simmer for 1 minute, letting these bright flavors meld together. You’ll notice the sauce begin to thicken slightly, which adds a beautiful richness to the overall dish, complementing the flaky cod perfectly.
Step 7: Return the Cod
Carefully place the seared cod back into the skillet, spooning the lemon garlic butter sauce over the fillets. Let the fish simmer in the sauce for an additional 2-3 minutes, until it flakes easily with a fork. This step allows the cod to absorb the flavors of the sauce while finishing off the cooking process.
Step 8: Finish and Garnish
Once the cod is cooked through and radiant from the sauce, remove the skillet from heat. Sprinkle with freshly chopped parsley for a touch of color and freshness. Your Lemon Garlic Butter Cod is now beautifully prepared and ready to serve immediately, inviting your loved ones to gather around the table!

How to Store and Freeze Lemon Garlic Butter Cod
Fridge: Store leftovers in an airtight container for up to 3 days. Reheat gently in the microwave or skillet over low heat, adding a splash of lemon juice to freshen the flavors.
Freezer: If you need to freeze Lemon Garlic Butter Cod, wrap it tightly in plastic wrap and then aluminum foil. It can be frozen for up to 2 months for best taste.
Reheating: Thaw in the fridge overnight before reheating. For an even better taste experience, reheat gently until just warm; avoid overcooking to maintain that tender texture.
Expert Tips for Lemon Garlic Butter Cod
• Fish Freshness: Always choose fresh or properly thawed cod for best texture and flavor. Frozen fish can result in a mushy sauce if not handled correctly.
• Searing Technique: Avoid overcrowding the pan, as this can steam the fish instead of searing it. Cook in batches for a perfect golden crust on your Lemon Garlic Butter Cod.
• Use a Fish Spatula: A fish spatula makes flipping the delicate fillets easier and minimizes breakage. It’s a must-have tool for this recipe.
• Temperature Check: Ensure the cod reaches an internal temperature of 145°F (63°C) for safety and perfect doneness. Using a thermometer takes the guesswork out.
• Herb Variations: Don’t hesitate to experiment with fresh herbs like thyme or dill in the butter sauce. They can elevate your Lemon Garlic Butter Cod to a new flavor dimension!
Make Ahead Options
These Lemon Garlic Butter Cod fillets are perfect for meal prep enthusiasts! You can season the cod fillets, wrap them tightly, and refrigerate them up to 24 hours in advance, which helps deepen the flavors. Additionally, the lemon garlic butter sauce can be prepared ahead of time and stored in an airtight container in the fridge for up to 3 days. When you’re ready to serve, simply reheat the sauce in a skillet, gently reintroduce the cod fillets, and simmer for a few minutes until heated through. This approach ensures your meal remains just as delicious and fresh, providing you with restaurant-quality results with minimal effort, ideal for those busy weeknights!

Lemon Garlic Butter Cod Recipe FAQs
How do I select the best cod fillets?
Absolutely! When choosing cod fillets, look for ones that are bright white with a slightly translucent appearance. The flesh should be firm and spring back when pressed, indicating freshness. Avoid any fillets with dark spots or a fishy smell, which are signs of age. If you opt for frozen cod, ensure it’s well-packaged without freezer burn.

To store your Lemon Garlic Butter Cod, simply place any leftovers in an airtight container in the fridge. They can be kept fresh for up to 3 days.

What should I do if my cod is overcooked?
If your cod happens to get overcooked and becomes dry, worry not! You can try to salvage it by creating a sauce with butter and adding a bit of cream or extra lemon juice. You can then toss the flaked cod in the sauce briefly to moisten it. Alternatively, you can turn it into a fish salad or add it to a pasta dish for extra flavor.
Is this dish suitable for people with dietary restrictions?
Yes! This Lemon Garlic Butter Cod is not only gluten-free and low-carb, but it also packs a high protein punch, making it great for those on keto diets.

Always double-check ingredient labels, especially on store-bought sauces or seasonings, to ensure they align with dietary needs.
Can I use other types of fish for this recipe?
Absolutely! If you can’t find cod or desire a different flavor, you can substitute with halibut, haddock, or tilapia. They all cook similarly and can absorb the delicious lemon garlic butter flavor beautifully. Just keep an eye on cooking times, as some fish may cook faster than cod.
