Baked Cod and Potatoes is a simple, delicious dish featuring cod fillets roasted on top of buttery, crispy, well-seasoned potato slices.
Today I would like to share an easy to prepare seafood main dish with you that I found online a while ago. The main ingredients are cod fillets and russet potatoes (along with butter, olive oil and spices). It’s a fairly simple recipe that will serve 3 people.
There are two cooking methods used to make the dish. Potatoes are roasted in the oven; the fish is added on top (same dish), then everything finishes cooking under the broiler in the oven. It’s a really nice tasting meal, and here is how to make it.

Prepare The Potatoes
Wash 2 large russet potatoes (or 3 medium- about 1 pound total), then remove the peels. Once they’re peeled, slice the potatoes into 1/8″ thick rounds (width-wise) using a sharp knife or a mandoline slicer. Place the potato slices in a medium bowl.
Combine 2 Tablespoons of melted butter and 2 Tablespoons of extra virgin olive oil in a separate bowl. Remove 1 Tablespoon of this mixture and set it aside (to drizzle on the fish later).
Pour the remaining 3 Tablespoons of the butter and olive oil mixture over the potatoes and toss them well, until the potato slices have been coated on all sides.
Grease a 9″ square baking dish with non-stick spray, then spread the coated potato slices evenly in the dish, keeping them in a single layer. Season the potatoes generously with salt, pepper, garlic powder and paprika.
Bake The Seasoned Potato Slices
Bake the potato slices at 400°F. for 35-40 minutes until the slices have softened and are light golden brown in color. Flip the potatoes over halfway through the baking time, then re-spread them in the dish and continue baking. TIP: I encourage you to check on the potatoes a couple of times while they bake to ensure they don’t get too crispy.
Remove the pan from the oven once the potatoes are finished cooking. Turn on the BROILER for the oven, and make sure the oven rack is moved to about 6 inches from the heat source for the final step.
Add The Cod Fillets
Now it’s time to add the cod fillets and finish cooking this dish! Place three 1″ thick cod fillets (with or without skin on the bottom) on top of the potato slices, leaving a small amount of space in between each one.
We used cod fillets with skin on (this time), then removed the skin once everything was ready, but this is your choice, however you prefer it. Drizzle or brush the reserved melted butter and olive oil mixture over the top of the fillets. Lightly season the fish with additional salt (if desired), then sprinkle them with fresh thyme leaves.
Time For The Broiler
When the broiler is hot and the oven rack is in place, put the baking dish back in the oven, about 6″ away from the direct heat of the broiler. Broil the fish for 7-10 minutes OR until the fish is cooked through, and the potatoes are crispy and browned.
Ours usually takes the full 10 minutes, but the time may vary depending on the thickness of the fish. Keep an eye on the fish while it broils. If you notice the potatoes begin to get too browned or start to burn slightly, simply move the dish further away from the broiler!
The baked cod and potatoes are done when the potatoes are browned and crispy, and the cod flakes easily with a fork and is cooked all the way through.
Serve The Baked Cod And Potatoes
Remove the baking dish from the oven and serve the baked cod and potatoes immediately. Serve the fish on top of the potatoes or serve the cod with the potatoes on the side.
Sprinkle more fresh thyme leaves on top of the fish before serving (if desired). We enjoy serving the baked cod and potatoes with a salad or a green veggie on the side.
I hope you have the opportunity to try this delicious seafood recipe and trust you will find it enjoyable. It’s a really uncomplicated recipe to make and has good flavors.
Thanks so much for stopping by and please come back again soon for more family-friendly recipes. Take care, may God bless you, and have a wonderful day.

Baked Cod and Potatoes is a simple, delicious dish featuring cod fillets roasted on top of buttery, crispy, well-seasoned potato slices.
- 2 large russet potatoes (about 1 pound) or 3 medium
- ¼ medium yellow onion thinly sliced
- 2 Tablespoons butter melted
- 2 Tablespoons extra virgin olive oil
- salt and pepper to generously season potatoes
- garlic powder to generously season potatoes
- paprika to generously season potatoes
- ¾ pound cod fillets (3 fillets) approx. 1" thick and 4 oz. each
- fresh thyme leaves (chopped) to lightly season fish
- additional salt (optional) to lightly season fish
Preheat oven to 400℉. Grease or spray bottom of a 9" square baking dish.
Wash and peel potatoes. Slice potatoes into 1/8" thick rounds using a knife or mandoline. Place potato slices in a bowl.
Combine melted butter and olive oil in a separate bowl. Remove 1 Tablespoon of mixture; set aside (to drizzle on fish later). Pour remaining butter/oil mixture on potatoes; toss well until potatoes are coated. Spread potatoes in prepared dish, in a single layer. Season generously with salt, pepper, garlic powder and paprika.
Bake the potatoes at 400°F. for 35-40 minutes until softened and light golden brown in color. Flip slices over halfway through baking time, then re-spread them in the dish; continue baking. TIP: Check on potatoes 2-3 times while they bake so they don't get too crispy.
Remove potatoes from oven. Turn on the BROILER: move oven rack to 6" below broiler heat source. Place cod fillets on top of potatoes. Drizzle reserved butter/oil mixture over the fish. Lightly sprinkle fish with additional salt (if desired), then sprinkle with fresh thyme leaves.
Put baking dish under broiler (6" away from heat source). Broil 7-10 minutes OR until fish is cooked through (flakes easily with a fork), and potatoes are crispy/browned. Time may vary depending on thickness of fish. TIP: Keep an eye on everything as it broils. If potatoes begin to burn, move baking dish further away from the broiler!
Remove from oven; serve immediately. Serve fish on top of the potatoes or with potatoes on the side. Enjoy!
