Ingredients you will need

Ingredients to make tuna noodle casserole.

Egg noodles – they can be medium, wide, or even extra-wide. If egg noodles are not an option, try penne, rotini, elbow macaroni, linguine, or spaghetti.
The creamy sauce is a combination of Greek yogurt (or sour cream), whole milk (or dairy-free), and a combination of sea salt, black pepper, garlic and onion powders.
White Albacore tuna packed in water is the best option for this dish. It is not oily and is solid enough to not fall-apart when stirring and serving.
Sliced mushrooms and defrosted, frozen peas are the traditional vegetables used, but broccoli or green beans would work as well.
Panko breadcrumbs mixed with grated parmesan cheese and softened butter create a delicious, crispy topping that bakes golden brown.
Chopped parsley as a garnish breaks up all the beige and adds a bright, fresh taste.
