Instructions
Step 1: Prep the Cod
-
Preheat oven to 375°F (190°C).
-
Grease a medium baking dish with butter.
-
Pat the cod fillets dry and season both sides with salt, pepper, and lemon juice (if using).
-
Arrange cod in the baking dish in a single layer.
Cod is a delicate fish. If it breaks apart, don’t worry – it still tastes great once smothered in sauce!
Step 2: Make the Mornay Sauce
-
In a medium saucepan, melt 2 tbsp butter over medium heat.
-
Whisk in 2 tbsp flour and cook for 1 minute to form a smooth roux.
-
Slowly add warm milk (and cream, if using), whisking constantly until smooth.
-
Cook for 4–5 minutes, stirring, until sauce thickens.
-
Stir in mustard, nutmeg, and season with salt and pepper.
-
Remove from heat, then stir in cheddar and Parmesan until melted and smooth.
The sauce should be thick enough to coat the back of a spoon but still pourable.
Step 3: Assemble & Bake
-
Pour the Mornay sauce over the cod, covering evenly.
-
In a small bowl, mix breadcrumbs, extra cheese, and melted butter.
-
Sprinkle topping evenly over the dish.
-
Bake in preheated oven for 25–30 minutes, or until:
-
Sauce is bubbling
-
Topping is golden
-
Cod flakes easily with a fork
-
Optional: Broil for the last 2–3 minutes for an extra-crispy topping.
