Description
White fish, salmon, and shrimp baked in a Dijon and herb cream sauce under a fork-ridged mashed potato and cheddar crust. Serves six and can be assembled a day ahead.
Ingredients
Units
- 1 lb cod or haddock fillets, cut into chunks
- 8 ounces salmon fillet, cut into chunks
- 8 ounces raw shrimp, peeled and deveined
- 2 lbs Yukon Gold potatoes, peeled and quartered
- 4 tablespoons unsalted butter
- 1/2 cup whole milk (for mash)
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 1/2 cup heavy cream
- 2 teaspoons Dijon mustard
- 2 tablespoons fresh flat-leaf parsley, chopped
- 1 tablespoon fresh dill, chopped
- 1 tablespoon fresh lemon juice
- 1 teaspoon kosher salt
- 1/2 teaspoon white pepper
- 1/2 cup frozen peas
- 1/2 cup shredded cheddar cheese
Instructions
- Boil potatoes in salted water until tender, about 15 minutes. Drain, mash with 4 tablespoons butter and 1/2 cup milk until smooth. Season with salt and set aside.
- Preheat oven to 400F.
- Melt 3 tablespoons butter in a saucepan over medium heat. Whisk in flour and cook 1 minute. Gradually whisk in 2 cups milk and cream. Cook, stirring constantly, until thickened, about 5 minutes.
- Remove from heat. Stir in mustard, parsley, dill, lemon juice, salt, and white pepper.
- Arrange the cod, salmon, shrimp, and peas in a 9×13-inch baking dish. Pour the sauce over the fish.
- Spoon the mashed potatoes over the top and spread evenly, using a fork to create textured peaks that will crisp in the oven. Sprinkle with cheddar.
- Bake 30 to 35 minutes until the filling is bubbling at the edges and the potato topping is golden. Let stand 5 minutes before serving.
Notes
- Using a mix of fish — white fish, salmon, and shrimp — gives the pie variety in texture and flavor. All one fish makes it monotonous.
- Creating peaks and ridges in the mashed potato topping with a fork gives more surface area for crisping — smooth, flat mash stays pale and soft.
- This assembles beautifully a day ahead. Refrigerate unbaked, then add 10 minutes to the oven time.
