Stir in the cheddar cheese until melted, then fold in the noodles and drained tuna. Stir to combine.
Transfer to a 9x13 or similar sized baking dish.
Whisk together the parmesan and breadcrumbs and sprinkle on top.
Cover and bake for 25 minutes, then uncover and bake for an additional 5-10 minutes to let the top brown (or simply broil for 1-2 minutes, keeping a close eye so it doesn’t burn).
