While some culinarians might scoff at the idea of fish with cheese, Newfoundlanders love a good scoff of Cod au Gratin indeed (a scoff is a meal, in NL vernacular of course), and have been doing so for generations. So, get flaked and enjoy this meal.

Classic Canadian Dish: Cod Au Gratin with Crispy Breadcrumb Topping
Ingredients
- 1 1/2 lbs cod fillets (deboned and skinned)
- pinch salt
- 1 Tbsp canola oil
- 1 yellow onion peeled and diced
- 3 Tbsp butter plus 2 Tbsp for crispy breadcrumb topping
- 3 Tbsp flour
- 2 cups milk
- 1/2 tsp salt
- 1 Tbsp lemon zest
- 1/2 tsp freshly ground black pepper plus more for topping
- 1 tsp dried oregano
- 1 cup breadcrumbs
- 1 cup Parmesan cheese grated
- 2 cups cheddar cheese grated
Instructions
- Preheat the oven to 375°F (190°C).
- Cut cod into bite-sized chunks and place in a casserole dish and season with a little salt. (Note: If using frozen cod, make sure to thaw completely and pat dry with a paper towel to remove excess moisture.)
- In a saucepan, heat canola oil on medium heat, add the onion and cook until just softened around 5 minutes.
- Add the 3 Tbsp (45 mL) of butter to the onion and melt, add 3 Tbsp (45 mL) of flour to make the roux. Slowly add 2 cups (500 mL) of milk to thicken and make a sauce.
- Once thickened, add 1/2 tsp (2 mL) salt, lemon zest, 1/2 tsp (2 mL) pepper and 1/2 tsp (2 mL) oregano and stir to combine. Then add 1/2 cup (125 mL) of the grated parmesan and 1/2 cup (125 mL) of cheddar cheese. Mix.
- Pour sauce over the cod and make sure it’s fully coated.
- To make crispy breadcrumb topping: melt 2 Tbsp (30 mL) butter in the microwave. In a medium bowl, add melted butter to breadcrumbs, then stir in half the remaining cheeses (about 1 cup/250 mL).
- Use remaining 1 cup (250 mL) of cheeses to cover the cod and sauce. Top with breadcrumb mixture and sprinkle with more black pepper and 1/2 tsp (2 mL) of oregano.
- Bake for 40 minutes or until brown and bubbly.
- Let cool for at least 20 minutes to set before serving. Can be served on its own with lemon wedges or on top of potatoes or rice.
