Why I Love This Baked Cod
My sweet neighbor and I don’t share a common language. But we do share a love of food. How we communicate, is through food.
I share dishes with her, and she with me. It’s a delicious endeavor and builds a bond that transcends cultures.
One day she surprised us with a lemon cod dish that was so incredible, I couldn’t get it out of my mind and wanted to share it with you. I don’t know exactly what she put in her dish, but this cod recipe is very close.
With a hint of spring and lemony flavors, this quick and easy weeknight dinner is full of flavor but special enough to serve others. I hope you enjoy it as much as we do!

Baked Cod Recipe Overview
Total Cook Time: 20 minutes
Servings: 4
Kitchen Tools: Baking pan
Baked Cod Ingredients
Here’s what you need:
For the Fish:
- Cod fillets: I’m using Icelandic cod, about 1-2 inches thick, skinless, and boneless. The “notes” section in the recipe cards gives you ideas on which fish doesn’t work as well.
- Small shallot, finely minced
- Salt and black pepper
- Lemon slices

For the Lemon Sauce:
The lemon sauce becomes a sauce in the oven. It begins very similarly to a compound butter.
- Butter (salted or unsalted)
- Lemon: Fresh lemon juice is best. You’ll also use its zest
- Garlic cloves, minced or pressed
- Dijon mustard
- Paprika
- Fresh parsley
How to Make this Cod Recipe
This recipe is a breeze to make, quick and easy, but oh-so-delicious! Here’s how to make this seafood dinner.
Step 1: Place fillets in baking dish and season
Place cod fillets in a baking dish, lightly brushed with olive oil, leaving space around the fish. Season both sides with salt and black pepper. Sprinkle minced shallots over the top of the fillets.

Step 2: Make the lemon garlic butter sauce
Stir the softened butter, parsley, lemon juice (1 1/2 tablespoons), zest from 1 lemon, garlic, Dijon, and paprika in a small bowl. Mix until smooth and spreadable.
Top each fish fillet with dollops of the lemon garlic butter mixture and then spread over the tops and sides.


Step 3: Bake
Bake for 15 minutes or until the fish is cooked, the cook time will depend on the thickness of your fillet. Remove from oven, transfer the fillets to a serving platter (or plates), and pan juices and sauce over the top. Serve with fresh parsley and lemon slices.

How to Tell When Your Cod is Perfect
Carry-Over Cooking: Remember, cod will continue to cook slightly after you remove it from the oven. So, err on the side of slightly undercooked if you’re unsure.
Flake Factor: Gently insert a fork into the thickest part of the fillet and twist slightly. If the cod flakes easily, it’s done! It should separate into tender, distinct layers.
Opaque Oasis: Perfectly cooked cod will be opaque throughout. No translucent or glassy areas should remain.
Internal Temperature: If you have a food thermometer, use it! Cod is cooked when it reaches an internal temperature of 145°F (63°C). Insert the thermometer into the thickest part of the fillet.
The “Spring Back” Secret: Gently press the surface of the cod with your finger. If it springs back slightly, it’s likely done. If it feels mushy or leaves an indentation, it needs more time.
Tips for Baking Cod
- Pat it Dry: Let’s talk about moisture. Cod, like any fish, releases moisture during cooking. Pat your fillets thoroughly with paper towels. This crucial step helps the fish sear slightly on the bottom, preventing that dreaded soggy texture.
- Preheat the Oven: We’re aiming for a 400°F (200°C) oven. Give it a good 10-15 minutes to preheat fully. This ensures even cooking and a beautiful, golden finish.
- Handle Gently: Place your cod fillets in a lightly greased baking dish. But here’s the secret: gently slide them in. Don’t drop them! This prevents the delicate flesh from breaking apart.
Making It Look as Good as It Tastes!
When serving this baked cod recipe, carefully drizzle the lemon-garlic butter sauce over each fillet for a beautiful glossy finish. Then, add a touch of elegance with a sprinkling of fresh parsley. And don’t forget the lemon slices!

Questions
Depending on the thickness of the fish fillet, cod will take around 15 minutes to cook when baked at 400°F. Thicker cod fillets can take up to 20 minutes. For doneness, look for an opaque appearance throughout, and if it flakes easily with a fork.
Most recipes recommend baking cod at 400°F (200°C).
What to Serve with Baked Cod
Serve cod with roasted vegetables, like broccoli, sauteed greens, or even a light quinoa salad.
Here, I’m serving with Sauteed Asparagus and roasted potatoes. After cooking the asparagus, I add a small vine of cherry tomatoes to the pan and let it sear for a few seconds.
How long does baked cod last in the fridge?
According to the USDA, baked fish and other seafood can be safely stored in the refrigerator for 3 to 4 days.
Variations to Try
- Smoked paprika can be used instead of paprika for additional flavor.
- Greek seasonings like oregano, paprika, and cumin (1/2 teaspoon) for 4 fish fillets add Mediterranean flavors.
- Old Bay seasoning (1/2-1 teaspoon) and lemon capers could also be used for a flavor variation.

Notes
- Fish: Any white fish will work great in this recipe. I’m using Icelandic cod, but Tilapia or Snapper works well, too! Delicate fish like flounder, Dover Sole, or small fish do not work as well. If using frozen fish, thaw it completely and pat it dry before proceeding with the recipe.
- Shallots: You can also substitute the white parts of green onions if preferred.
- Garnishing Ideas: Serve the fillets on top of some of the baked lemon slices. Spoon additional sauce over the top of each fillet.
