Preheat your oven to 180°C (350°F).
Cook the pasta in a pot of boiling salted water until al dente, then drain and set aside.
In a saucepan, melt the butter over medium heat. Stir in the flour and mustard powder to form a paste.
Gradually add the milk, stirring constantly, until the mixture thickens into a smooth sauce.
Add salt and pepper to taste.
Stir in the cheddar cheese until melted and smooth.
Add the canned tuna and cooked pasta to the sauce, mixing well to combine.
Transfer the mixture to a baking dish and sprinkle the breadcrumbs evenly over the top.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and the casserole is heated through.
Remove from the oven and let it cool slightly before serving.
