Instructions

Preheat the oven

Preheat your oven to 375°F (190°C).

Make the béchamel sauce

In a saucepan, melt butter over medium heat. Stir in flour and cook for 1 minute. Gradually whisk in milk until smooth. Add salt, pepper, and nutmeg. Cook until thickened, about 5 minutes.

Pro tip: Ensure the sauce is smooth by whisking continuously.

Prepare the baking dish

Lightly grease a 9x13-inch (23x33 cm) baking dish.

Pro tip: Use butter or non-stick spray for greasing.

Layer the ingredients

Layer half of the potatoes in the baking dish. Add half of the cod, then pour over half of the béchamel sauce. Repeat layers with remaining potatoes, cod, and sauce.

Pro tip: Overlap potato slices slightly for even coverage.

Add cheese and breadcrumbs

Sprinkle shredded cheddar cheese and breadcrumbs evenly on top.

Pro tip: For extra flavour, mix breadcrumbs with a little melted butter.

Bake the gratin

Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and potatoes are tender. Let it rest for 10 minutes before serving.

Pro tip: Check doneness by inserting a knife into the potatoes; it should slide easily.
