“Old School” Tuna Cashew Casserole is a simple, easy to throw together casserole with cashews, chow mein noodles, tuna and celery… just the way we learned to make it in high school cooking class!"Old School" Tuna Cashew Casserole is a simple casserole with cashews, chow mein noodles, tuna and celery... the way we made it in high school cooking class!
When I was in High School (MANY years ago), I took a Gourmet Foods class. This recipe for “Old School” Tuna Cashew Casserole was one of the recipes we learned to prepare.  If you’re like me, you see the ridiculous humor in a simple tuna casserole being called “gourmet food”, but hey… back then, maybe it was?

I’ve made this recipe for tuna cashew casserole many times over the years, but I still giggle to think it is anything even remotely compared to gourmet food.  Nowadays I like to think of it as a “fairly economical way to feed a family of 4” casserole (especially when it only takes one can of premium tuna as the main ingredient!).

This tuna noodle casserole is completely simple, and so easy to prepare! The casserole can be served just as it is, straight from the oven, or it can be served on top of rice or noodles.  This time I made it… “as is”, so you can see from the photos what it is supposed to look like when done. Here’s how to make it:

How To Make “Old School” Tuna Cashew Casserole

Set aside 1/2 of the chow mein noodles before beginning (you will need them for crunchy topping later!).  Place the remaining ingredients (tuna *I used albacore*, celery, chow mein noodles, cashews, onion, seasonings, water, and cream of mushroom soup) in large bowl.

Stir well until all ingredients have been combined (see how easy it is?).  Pour into a 2 quart baking dish that has been sprayed with non-stick spray.  Sprinkle the top of casserole with the reserved chow mein noodles.

Bake The Casserole

Bake, uncovered, at 325 degrees for 40 minutes. The tuna noodle casserole should be lightly browned and slightly bubbly around the edges when done.  Remove from oven.

Let casserole cool for just a minute or two, then serve as is, or serve on top of rice or noodles.

Here’s what the tuna cashew casserole looks like right after placing it on a serving plate.  The recipe, as written, makes 4 servings, and is easily doubled.  The casserole has good flavor and crunch from the celery, cashews, and chow mein noodles. It’s unusual that this casserole does not have pasta noodles in it (which is fairly common), but this is how we were taught to make it back then!

I would classify this simple casserole as “comfort food”, rather than “gourmet food”, but am still glad to have kept this recipe since making it in High School.

When I cooked it this time, I made it to have around for a quick lunch, rather than as a main course meal, but either way, it’s a quick and easy way to get tasty food on the table!

8 Comments on “Old School” Tuna Cashew Casserole

  1. Oddly my husband asked for this today. I had not made it in years, but found your recipe, searched the grocery for the chow mein noodles ( hallelujah, no supply chain problem)
    He really enjoyed it, so thanks for having it here.

  2. I always make this a couple of days after Christmas, but replace the canned tuna with my leftover turkey! It’s delicious and we plan on having it every year!

  3. I haven’t made this for years but decided to make it for myself. I added diced red pepper, celery, onion and snow peas which weren’t in the original recipe I know but they were delicious. No cashews so tossed in a handful of slivered almonds. I don’t know if my girls would have eaten back in the day with all my veggie add ins but I know they would now.

    • Good afternoon, Donald! That is a GREAT question! I used a regular sized 10.5 ounce can of the soup. I can see where that would be hard to figure out based on what I had in the printable recipe. I have now gone into the blog and changed the post to indicate the size can of soup needed. Thank you so much for taking time to write, which helped me be more accurate with the ingredient list. Thank You! Have a wonderful Christmas!

  4. Thanks for posting this. This recipe was a staple at this newlywed’s table during graduate school back 50 years ago! I am almost 75 and recovering from my second total knee replacement. Had a yearning for this “comfort” food. Now I have iot again! Merry Christmas

    • Good morning, Mona, and Merry Christmas to you, as well! Hope your knee replacement recovery is going well, and that you will be up and at it again really soon! Thank you for taking the time to write. I appreciate it. God Bless You.
