How to Make the Healthy Lemon Butter Baked Cod Recipe
Step 1: Preheat and Prep
Start by preheating your oven to 400°F (200°C). Lightly grease a baking dish with olive oil or line it with parchment paper for easy cleanup.
Step 2: Season the Cod
Pat the cod fillets dry with a paper towel. Season both sides generously with salt, black pepper, and a pinch of paprika. This adds a mild kick and gorgeous color.
Step 3: Prepare the Lemon Butter Sauce
In a small saucepan, melt butter over low heat. Stir in minced garlic, freshly squeezed lemon juice, lemon zest, and a tablespoon of chopped parsley. Let it simmer for 1-2 minutes until aromatic.
Step 4: Assemble and Bake
Place the seasoned cod in the baking dish and pour the lemon butter sauce evenly over each fillet. Bake for 12-15 minutes or until the fish flakes easily with a fork. Thicker fillets may need a minute or two longer.
Step 5: Finish and Garnish
Once baked, spoon some of the pan sauce over the fillets. Sprinkle additional parsley and an optional dash of red pepper flakes for heat.
Recipe Variations and Possible Substitutions
If you’re out of cod or prefer a different white fish, halibut, haddock, or tilapia are excellent substitutes. Just adjust the cooking time depending on the thickness of the fillets.
For a dairy-free version, swap the butter with vegan butter or use extra virgin olive oil. You can also add thin lemon slices on top before baking for a more intense citrus flavor.
Don’t have fresh garlic? Use garlic powder in the lemon butter mixture. Craving a Mediterranean twist? Add a handful of capers or chopped sun-dried tomatoes to the baking dish.
This recipe is a blank canvas you can customize to suit your mood or pantry.
Serving and Pairing Suggestions
This Healthy Lemon Butter Baked Cod pairs beautifully with a variety of sides. I often serve it over a fluffy bed of jasmine rice or quinoa to soak up every bit of the lemon butter sauce. For something lighter, a crisp garden salad with cucumbers, cherry tomatoes, and a lemon vinaigrette is a refreshing choice.
It also goes wonderfully with roasted asparagus, steamed green beans, or my favorite Oven Roasted Root Vegetables. The mildness of the cod makes it easy to pair with any seasonal vegetables you love.
If you’re feeling a little indulgent, serve it with a side of creamy mashed potatoes or garlic butter noodles. And don’t forget a chilled glass of white wine – Sauvignon Blanc or Chardonnay are both excellent picks.



Storage and Reheating Tips
Store any leftover cod in an airtight container in the refrigerator for up to 2 days. To reheat, place it in a preheated oven at 300°F for about 10 minutes or until warmed through. You can also gently reheat it in a skillet over low heat with a splash of water or broth to keep it moist.
Avoid microwaving if possible, as it can dry out the delicate texture of the fish. And while freezing is possible, it’s best enjoyed fresh for optimal flavor and texture.
