Directions

1. Thaw cod and chop into bite sized pieces. If using salmon, do the same and remove the skin.

2. Bring a large saucepan of salted water to a boil. Add potatoes and cook for about 20 minutes or until very tender. Drain well and place in a bowl. Mash with 3 tbsp butter until well combined. Season with salt and pepper and set aside.

3. While the potatoes boil, begin to heat 4 tbsp butter in a skillet over medium heat. Sautée the onion for 5 minutes or until soft. Add cheddar cheese, cream, Dijon mustard, and lemon juice. Stir frequently as it cooks, for about 3-5 minutes or until the cheese has melted. Remove from heat.

4. Add the cod to the skillet and stir until well combined.

5. Preheat oven to 400 degrees.

6. Transfer filling to a pie pan and spread the mashed potatoes over the top to create a crust.

7. Bake until sauce is bubbling and potato crust is golden, about 45 minutes.

8. Garnish with chives.

9. Serve hot and enjoy!
