Preheat the oven to 350°F and grease a 2-quart casserole dish.
Cook the noodles until slightly underdone; drain and rinse.
Sauté the onion and celery in butter until soft.
Mix the soup, mayonnaise, milk, garlic powder, and onion powder until smooth.

Notes
Chef Jenn’s Tips
If you want to prepare this dish ahead of time, assemble the casserole but wait to add the bread topping until you’re ready to bake. This will keep it nice and crunchy.
Use water-packed canned tuna for a lighter flavor.
If you’re a cheese lover, feel free to add more cheese to the topping for extra cheesiness.
