Creamy Cod and Potato Bake

Creamy cod and potato bake is an easy weeknight meal made from a simple potato mash and cod cooked in a cream sauce. Every bite tastes decadent and flavorful and it comes together quickly!

Creamy Cod and Potato Bake

This creamy cod and potato bake can be broken into three parts: the potato, the fish, and the baking.

The Potato

To prepare the potato start by prolong 4-5 russet potatoes. Then chop into large even pieces. Place the potato in a large pot of cold water and put on the stove. Bring the pot to a boil and then cook until a knife inserted into a potato slides in easily without any resistance.

Boiled Potatoes

Once fully cooked, drain the potatoes and season with salt and butter (or salted butter). Mash the potatoes until it reaches your desires consistency (some prefer smooth, some prefer chunky).

Mashed Potato Layer

Taste the potatoes and season with salt if it needs it. Then pour the potatoes into a baking dish, I use a 13×9 casserole dish. Spread out the potatoes evenly and set aside.

The Cod

To prepare the cod, start by washing 2 pounds of cod and cut into bite size pieces. Set aside. In the meantime, heat a pot on medium heat and add a little olive or grape seed oil. Add a medium chopped onion and sauté gently-just until translucent.

Add 1/2 cup heavy cream and either dried or fresh parsley. Then add the prepared cod fish straight into the cream and bring to a simmer. Season lightly with salt and black pepper

The Baking

To bring the dish together, use a slotted spoon to scoop up the cod pieces and place evenly over the mashed potatoes.

Continue to simmer the cream sauce until it’s thickened. Check the cream sauce for salt and add any if needed. The saltiness will be more concentrated after thickening the cream, so it is important to start off with only a little.

Pour the cream sauce evenly over the fish. Then sprinkle over more parsley. And grate on some good quality Parmesan cheese.
