Tuna Noodle Casserole

You guys, I made you a casserole- TUNA Noodle Casserole!  But this isn’t your grandmother’s casserole.  Well, in truth, I can’t say that because I don’t know your grandmother.  But I am guessing her casseroles weren’t lightened up, or Cajun spiced, or topped with cheesy panko breadcrumbs.  Just a hunch.

But honestly, I did make my grandmother’s tuna casserole – or a version of it  – all the time in college.  It was my guilty pleasure that was so simple to throw together and its creamy, naughty goodness was nothing short of addicting… so addicting.

This from-scratch Tuna Casserole recipe, however, doesn’t contain any “cream of” soups and is wonderfully cream, flavorful and about to become a new family favorite!

Aren’t we glad Tuna Casserole is tuna casserole – we could all be eating sardine casserole!  Canned tuna was first produced in Australia in 1903 and quickly became popular.  It was the alternative to canned sardines.  Tuna now ranks second for the most consumed seafood product in the U.S., with 2.7 pounds consumed per person every year – hopefully of tuna casserole 😉.

With Australia spearheading the tuna canning empire, it makes sense to look there for tuna casserole beginnings.  Down under, they have a dish called Tuna Mornay.  It is tuna served with Mornay sauce, which is a béchamel with cheese.  They also add peas corn and wheat pasta – so essentially from scratch Tuna Noodle Casserole.

This Australian Tuna Mornay morphed into American Tuna Casserole in 1950’s with the advancement of canned and processed foods, specifically “cream of” soup as well as canned peas.  Their convenience and low cost won everyone over, and soon THIS modernized Tuna Noodle Casserole will win you over with its luscious creaminess, explosion of flavor and comforting layers of YUM!

What Tuna is Best?

The tuna you use does affect the end result of your tuna casserole – after all this is TUNA Casserole.  For best results, I recommend:

  • Solid White Albacore. Your tuna cans will be labeled either “solid white albacore” or “chunk light tuna.”  I recommend solid white albacore as it is exactly what it sounds like – more solid piece of tuna instead of smaller chunks.  It tastes far less “fishy” with a superior texture.  The solid white will naturally flake apart as it is stirred into your casserole into the perfect size pieces that will hold up better in your oven verses chunk light tuna which will dissolve into smaller pieces and not retain their structural integrity.
  • Pacific Albacore Tuna. 60% of all tuna that is caught and harvested comes from the Pacific Ocean.  Pacific albacore tuna caught along the U.S. Pacific coast recently received sustainability certification through the Marine Stewardship Council. Which means that they are not over harvesting and they are using ethical business practices.
  • Water Packed Tuna. Please use water-packed tuna as opposed to tuna packed in oil. The tuna is already juicy without the oil which can make it unappetizing, greasy, and of course add unnecessary calories.
  • Canned or fresh. You can use canned or cooked fresh tuna.  I am all about canned because it is one of the beauties of this dish that makes it SO easy!  If you choose to use fresh, make sure it is not overcooked because it is going back in the oven.  Flake fresh tuna into large bite size pieces.


Egg noodles are the classic noodles used in Tuna Noodle Casserole recipes.  I like to use egg noodles because their fluffy, silky texture holds their form when baked and their texture is simply palate pleasing.  I have tried other pastas in this recipe and don’t liked them nearly as well.  There is a reason it is called Tuna NOODLE Casserole.

That being said, if you are in a bind and don’t have egg noodles stocked, you can still make this Tuna Casserole with any medium noodle you have such as cellentani, fusilli, rotini, or even tortellini.


Tuna casserole can be topped with a number of topping but the important factor is that they add a contrasting CRUNCH to the creamy casserole.  Common topping includes panko, bread crumbs, crushed Ritz crackers, crushed potato chips, crushed cornflakes, or canned fried onions.

I have topped my Tuna Noodle Casserole with panko for its delightful crunch and it is easy to keep stocked without becoming stale, but feel free to top your casserole with YOUR favorite topping!


This Tuna Noodle Casserole recipe contains:

  • ½ cup Parmesan cheese
  • ½ cup Mozzarella cheese
  • 1 cup cheddar cheese

If you would like an even cheesier casserole than add an addition one cup 1 cup sharp cheddar cheese.  You can also swap the Parmesan and mozzarella for cheddar cheese if that’s all you have on hand.

If you don’t like want cheesy Tuna Casserole, then simply omit the cheese completely.  No substitutions are needed.

Tuna casserole should be baked uncovered so the crunchy topping -whether it be breadcrumbs, panko, Ritz, etc. can bet crispy.  If your topping is getting too golden before the casserole is heated through, then you can cover then uncover the last few minutes of baking to crisp up.

Tuna Casserole Recipe Variations

  • You can add any veggies your heart desires. I personally LOVE the texture of peas in Tuna Casserole, so I wouldn’t skip them, but rather you can add additional veggies such as corn, green beans, zucchini, carrots, etc.
  • You can swap the mozzarella and Parmesan for sharp cheddar or get fancy with gruyere.
  • You can mix up the toppings with fried onions, crushed potato chips, Ritz, etc.. I just don’t recommend plain breadcrumbs because they don’t bake up nearly as crunchy.
  • If you don’t have tuna, try using shredded chicken!
  • Make sure to cook the egg noodles al dente, which means they still have a little bite to them. This will ensure you avoid mushy noodles because they will continue to bake in the oven.


Leftover Tuna Noodle Casserole should be stored in an airtight container in the refrigerator.  When properly stored, it is good for last 3-5 days.


Tuna Casserole is a wonderfully comforting main dish that pairs beautifully with:


Yes!  Dinner just got easier with Tuna Casserole you can pull out of the refrigerator and bake!

To make ahead:

  1. Assemble Tuna Casserole up to the point of adding the panko topping. You will want to add the panko just before baking or it will become soggy if refrigerated.
  2. Cover tightly with plastic wrap and refrigerate for up to 3 days.
  3. Remove casserole from the refrigerator 20-30 minutes to bring to room temperature so it cooks evenly.
  4. Sprinkle evenly with panko topping.
  5. Bake for 35-40 minutes (an additional 5 to 10 minutes to the total cooking time) or until warm and bubbly.


Tuna Casserole can be frozen before or after it is baked BUT baked, frozen casserole does not hold up as well as the topping gets soggy and the noodles can get soft and even mushy.  For best results, freeze unbaked frozen casserole.

To freeze unbaked Tuna Casserole:

  1. Assemble tuna casserole but omit panko topping.
  2. Wrap a couple times in plastic wrap and then foil so it is very well sealed.
  3. Label and freeze for up to 6 months.
  4. When ready to use, defrost completely in the refrigerator, this may take up to 48 hours.
  5. Remove casserole from the refrigerator 20-30 minutes to bring to room temperature so it cooks evenly.
  6. Top with panko topping.
  7. Bake for 35-40 minutes (an additional 5 to 10 minutes to the total cooking time) or until warm and bubbly.

Is Tuna Casserole Good For you?

To keep this Tuna Noodle Casserole Recipe lightened up, I used only 1 tablespoon butter and zero cream. I’ve also stuck with a minimal amount of cheese but feel free to amp up the cheese to fulfill your cheesy desires.  Personally I don’t think it really needs it because of all the amazing textures going on, but then again – more cheese can never be a bad thing.

Can Pregnant Woman Eat Tuna Casserole?

Pregnant and nursing women may eat up to 12 ounces a week of LIGHT canned tuna and up to 6 ounces a week of FRESH or canned WHITE (not light) tuna, as albacore tuna has more mercury than light tuna.  This means, pregnant women can safely eat a serving of canned light tuna every three or four days and a serving of canned albacore tuna every nine-to-14 days, according to the Natural Resources Defense Council.

    Tuna noodle casserole was one of my absolute favorites growing up. To this day, I still love the smell of that fishy, cheesy bake in the oven. This will be such an excellent twist on a old classic for my family!
