Why you will love Cheesy Tuna Casserole

This dish is an easy weeknight dinner that only takes about 30 minutes. Comfort food at its finest, the crunchy topping (with the help of buttery Ritz crackers) is so satisfying. 

Super cheesy, this dish has cheese on top and the inside, making sure every bite contains the best flavor. 

Filling and delicious, this savory dinner casserole makes excellent leftovers for next-day dinners as well.


  • Egg noodles – I believe that only wide egg noodles should be used in a tuna casserole. They have the right amount of hold without being too thick. While pasta is often interchangeable, you do not want too dense of a casserole in the creamy sauce—just prep per package instructions.
  • Tuna – Make sure to get canned tuna in water and not oil. I like white tuna, but it is acceptable to use light tuna. 
  • Frozen peas and carrots – Grab a bag of frozen peas and carrots and let them thaw at room temperature or in the fridge overnight. Remove any excess water before use. Typically this isn’t an ingredient you should use from cans as canned veggies tend to be softer, and you want the crisp-tender version that frozen provides this dish.
  • Cream of mushroom soup – This super creamy Campbell’s cream soup is one of the main ingredients for a burst of delicious flavor. And because it’s canned, it’s likely right in your pantry! Now traditional throwback tuna casserole recipes like this always use Cream of Mushroom, but it’s the creamy part that counts. If you hate canned soup, you can test out replacing it with sour cream or a half sour cream and half mayo blend for a still creamy white sauce taste without the soup. You will lose some of the overall flavors, however.

  • garlic powder + salt + black pepper
  • cheddar cheese

Ritz Cracker Topping

  • Ritz Crackers – I prefer a Ritz cracker topping on casserole dishes like these. I usually have them in the pantry, and it makes it easy. But growing up, my mom always crunched up Ruffles or Lays potato chips to make a crispy topping. You can also use panko bread crumbs if you prefer.

Can you Freeze Casseroles?

Typically you can freeze casseroles like this one. As with any fridge or frozen foods, it must be tightly sealed from air with saran wrap or in an air tight container and its smart to mark with the date.
Once ready to serve, defrost in fridge (which will likely take the night) and then bake the next day until heated through. Remember that cold items take longer in the oven, so you may have to cover the top with foil to prevent your tops from burning.
Overall freezing and defrosting varies depending how much you are freezing and your oven, so you may have to monitor.

  1. Jessica Draeger says:

    Enjoyed this casserole. A little too much garlic for us. Next time I’ll use 1/2 tsp instead.

  2. Blossom Smith says:

    My 3 young girls have been making this for our family since we found it here several years ago. At the time they were 7 7 and 5 years old. One is an extremely picky eater but when she gets to cook this she can’t seem to get enough. I’ve even convinced them to add extra peas to the dish. Now the only problem is keeping track of who’s turn it is to cook it!:)

    1. Trisha Haas says:

      Awesome! So glad to hear that other kids are in the kitchen too. My kids love to cook (more than eat what they cook too, lol).


  3. I just pulled this out of the oven and it tastes fantastic. I baked it for an extra 5 minutes or so.
    This will be gone by tomorrow.

    1. Trisha Haas says:

      Yay! Tuna casserole really is one of my very favorite comfort foods. I am so glad you enjoyed!


  4. Ingredients list 2 cans of Mushroom soup but direction says to 1 CAN?

    1. Trisha Haas says:

      I said to “add can of mushroom soup” and I think I just inadvertently left off the “s” and didn’t catch it but the ingredient list IS correct. Its 2 cans. Thanks for pointing out the mistake!
