👨🍳 Instructions
- 1
Preheat oven to 400°F (200°C). Grease a 9x13 inch baking dish.
💡 Tip: Ensure the baking dish is evenly greased to prevent sticking. - 2
Cook macaroni according to package directions until al dente. Drain and set aside.

Gently simmer the fish in lightly salted water for 5-10 minutes until flaky. Drain, reserving about 1 cup of the poaching liquid. Break the fish into bite-sized pieces.

In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 2 minutes to form a roux.

Gradually whisk in the milk and reserved poaching liquid until smooth. Bring to a boil, stirring constantly, until thickened. Stir in salt, pepper, and nutmeg.
💡 Tip: Whisk continuously to prevent lumps. - 6
Separate the eggs. Whisk the egg yolks into the warm sauce. In a separate bowl, beat the egg whites until stiff peaks form.
💡 Tip: Ensure the sauce has cooled slightly before adding yolks to prevent scrambling. - 7
Gently fold the cooked macaroni and flaked fish into the sauce. Then, carefully fold in the beaten egg whites until just combined. Be careful not to overmix.
💡 Tip: Folding in the egg whites will make the gratin lighter and fluffier. - 8
Pour the mixture into the prepared baking dish and sprinkle evenly with breadcrumbs or crushed crackers.
💡 Tip: For extra crispiness, you can dot the breadcrumbs with a little extra melted butter. - 9
Bake for 40 minutes, or until golden brown and set.
