Best Tuna Casserole Recipe

Every cook in America has his or her own tuna casserole recipe. It is truly a classic. I love how this easy tuna noodle casserole tastes both creamy and fresh, but the absolute best part is the crunchy topping. You won’t believe how crunchy and delicious it is! In my opinion, it makes it the best homemade tuna casserole ever.

Ingredients you’ll need:

  • Egg noodles: these curly noodles are soft and make the casserole look and taste amazing
  • Mixed veggies: you can use any veggie you love. I used chopped onions, red bell pepper, celery, and peas. I love how their different colors make the dish come alive
  • Canned tuna: water-packed tuna is my tuna of choice
  • Cream of mushroom soup: the condensed kind. It will be the base for the sauce
  • Milk: helps dilute the cream of mushroom
  • Cheddar cheese: please shred your own cheese, the difference between freshly shredded and store-bought pre-shredded cheese is enormous. You will use it for the filling and the topping
  • Parsley: I love the freshness it provides to both the filling and the topping
  • Panko breadcrumbs: please don’t use regular breadcrumbs, the topping will not be as crunchy!
  • Butter: it helps bind together the topping ingredients.

How to Freeze Tuna Casserole?

If you have any leftovers, let them cool completely and place them in an airtight container and freeze them for up to three months. If you don’t have an airtight container, wrap the leftovers twice in plastic wrap and once in foil.

How to reheat Tuna Casserole?

Thaw any leftovers overnight in the fridge and let them stand at room temperature for 30 mins to one hour. Reheat them in a 350 F oven until bubbly. You can use the microwave to reheat them, but the topping will not be crunchy.

What to serve with Tuna Casserole?

Tuna casserole is a complete meal in itself, but I like to serve a side salad with almost all my meals. My family’s all-time favorite is Tomato Cucumber Onion Salad. It’s super fresh and whenever I have them on hand, I add chopped avocado as well.

For dessert, I either surprise them with my amazing Pineapple Uside-down Bundt Cake Recipe or if I really want to indulge, I go for my Chocolate Peanut Butter No-Bake Dessert.
