Lemon Butter Baked Cod
Not rated yet. Be the first.
Quiet falls over the table for the first few bites: flaky cod with a spoonful of garlic, white wine and lemon butter over the top. Twenty-five minutes and one baking dish.
The short version
Salt cod fillets, bake at 400°F for about 12 minutes, and make a quick garlic, wine and lemon butter in a skillet while they cook. Spoon it over and bake 2 to 4 minutes more, until the fish flakes. Pull it when it turns opaque, not later.
What makes ours better
small changes, very loud compliments
-
Salt the cod 15 minutes ahead. Salt pulls a little moisture out and then back in as it dissolves, so the fish is seasoned through and stays juicier. It's the cheapest insurance against dry cod.
-
Make the sauce on the stove, not in the baking dish. Butter, garlic, wine and lemon simmered for a few minutes turn into a glossy sauce. Poured raw over fish, the butter just separates into grease.
-
Add the sauce for the last few minutes. The fish takes on the flavor without baking in a puddle, which keeps the top from going soggy.
-
Finish with lemon zest and parsley. Fresh zest and herbs go in off the heat, so the sauce tastes bright instead of cooked down.

Steps
apron on. phone down. mostly.
-
Salt the cod
Pat the fillets dry, set them on a plate, and sprinkle both sides with the salt and pepper. Leave them at room temperature for 15 minutes. Meanwhile, heat the oven to 400°F and set a rack in the middle.
About 15 min. Cook mode has a timer for this step.
-
Oil the dish
Brush the olive oil over the bottom of a 9×13-inch baking dish. Pat the cod dry once more, since the salt will have drawn out some moisture, and lay the fillets in the dish with space between them.
-
Bake the cod
Bake for 10 to 12 minutes, until the fish is just turning opaque at the center and the edges have started to flake.
Thin tail pieces cook faster. Tuck the tail underneath to double it up, or pull it out early.
About 10 min. Cook mode has a timer for this step.
-
Make the sauce
While the fish bakes, melt the butter in a small skillet over medium heat. Add the garlic and pepper flakes and cook for 30 seconds, until fragrant but not browned. Pour in the wine and simmer for 2 to 3 minutes until it has reduced by about half. Take the pan off the heat and stir in the lemon juice, zest and ¼ teaspoon salt.
About 3 min. Cook mode has a timer for this step.
-
Sauce and finish
Spoon about half the sauce over the cod and return the dish to the oven for 2 to 4 minutes, until the fish flakes easily with a fork and reads 135°F in the thickest part.
About 3 min. Cook mode has a timer for this step.
-
Serve
Spoon the rest of the sauce and any pan juices over the fish, scatter the parsley on top, and serve right away.
Good to know
read this before somebody asks for seconds
- Thick center-cut fillets can take up to 15 minutes before the sauce goes on. Thin ones need only 8. Go by the flake test, not the clock.
- Haddock, halibut, pollock and mahi-mahi all bake the same way. Frozen fillets work if you thaw them overnight in the fridge and pat them very dry.
- Serve with rice, orzo or roasted potatoes to catch the sauce. Roasted asparagus bakes alongside at the same temperature.
- Storage. Leftover cod keeps 2 days in the fridge in an airtight container. Reheat in a low oven or flake it cold into a salad.
Questions, answered
asked and answered at the kitchen counter
How do I know when baked cod is done?
It turns from translucent to opaque white and flakes easily when you press it with a fork. An instant-read thermometer in the thickest part should read about 135°F. It will carry over a few degrees.
What temperature should I bake cod at?
400°F works for most fillets. A hotter oven cooks thin pieces too fast, and a cooler one takes longer and dries the fish out.
Can I bake cod from frozen?
You can, adding about 50 percent to the time, but it releases water and the texture suffers. Thaw overnight in the fridge for the best result.
Why is my baked cod watery?
Fish that wasn't dried before baking, or frozen fish that wasn't thawed well, will pool liquid. Pat the fillets dry and drain the dish before saucing.
Can I make this without wine?
Yes. Use chicken broth and add a small squeeze of extra lemon at the end for the acidity.
