Tuna noodle casserole is a classic meal that offers comfort and convenience. Although the variations on the dish are many, and most of us have a family tweak that makes it extra special, most home cooks use canned soup, which is an ingredient that because of its high sodium content isn't suitable for everyone. Our recipe instead uses an easy homemade creamy sauce to achieve the perfect texture of a soft and decadent casserole, just the way we remember it.

The casserole can take on many vegetables of your liking; we used meaty mushrooms and peas, but broccoli florets or chopped spinach also make a great pair, adding texture, color, and nutrition. For the tuna, go with solid white albacore canned in water, and choose broad egg noodles unless a dietary restriction or egg allergy prevents it—in that case use any short pasta of your liking and skip the mayonnaise in the sauce as it also contains eggs. Serve with a simple salad with a bright lemon vinaigrette for an easy and flavorful meal.

How to Make Your Own Breadcrumbs

If you have a loaf of bread that has become stale, making homemade breadcrumbs is very simple. Simply tear the loaf into pieces and process in a food processor until finely ground. Freeze the crumbs in a food storage bag and use them as needed.


For toasted breadcrumbs, spread the crumbs out on a rimmed baking sheet and bake in a preheated 325 F oven for 12 to 14 minutes, until browned and crunchy. Keep in an airtight container for a couple of weeks.

How to Store Tuna Casserole

Leftovers should be stored in an airtight container in the fridge for up to three days.

  • To reheat the tuna noodle casserole, use a microwave or place in a 350 F oven until hot.
  • Freeze tuna noodle casserole to have it ready for a last-minute meal. Cook the pasta and sauce and assemble everything except for the breadcrumbs. Cool, wrap tightly, and freeze for up to three months. Cook directly from frozen in a 350 F oven, for 25 minutes, covered in tin foil. Take out of the oven and top with the buttery breadcrumbs. Place back in the oven and bake, uncovered, for an extra 25 minutes until the topping is crunchy.

Other Toppings, Spices, and Add-Ons

Our casserole makes a great template for you to add other ingredients of your liking:

  • Substitute the breadcrumbs for French fried onion rings or crushed potato chips.
  • Sauté 1/2 cup of thinly sliced celery or a combination of celery with 1/4 cup of chopped onion, and use instead of mushrooms.
  • Add 1 cup of shredded cheese to the thickened sauce before you add the mayonnaise.
  • Add a pinch of red pepper flakes to the breadcrumb mixture, or a dash or two of tabasco to the sauce.
  • Add 1/4 cup of Parmesan or Pecorino cheese to add extra tang and make the topping extra crunchy.


Salt and pepper can add additional flavor to this dish but if using canned breadcrumbs or potato chips as a topping, go lighter on the salt as these ingredients will already include salt.
