Cheesy tuna noodle casserole is an easy and classic dinner dish that the whole family can enjoy. With Ritz cracker crumbs on top, green peas, and lots of noodles and cheese, this dish is worthy of seconds.
So believe it or not, I was into my mid 20's before ever trying tuna noodle anything, and it was only because these are meals my husband grew up eating. Of course, I make my own adaptions every time and adjust it based on what I have on hand so it's never made the same way twice. This simple tuna noodle casserole always turns out delicious.
To keep it simpler on my memory I made up a rule of 2 for my tuna noodles when I'm cooking in a 9x13 baking dish. This is to make sure I don't get dry noodles and I get the same results more often than not.
The rule of two is simple, 2 cans of this, 2 cups of that, while not everything is done in pairs, it really does help me to remember the quantities needed for this baked tuna noodle casserole.
- Egg noodles
- Frozen peas
- Cream of mushroom
- Canned tuna

🍴 Recipe Tips
If you want to use canned peas in this easy tuna noodle casserole recipe, you can. I used to do it this way because that's what my husband said he was used to, but I've since found that frozen gives a prettier color and a burst of freshness once baked that keeps this dish from feeling depressing and makes it a little more comforting if you know what I mean.
I didn't always add the Ritz cracker on top either. For a long time, I made it plain without a topping. Then I noticed others used Panko, so I tried that too and they were flavorless. Finally, when I took inspiration from my chicken divan casserole and grabbed a sleeve of crackers. The rest was history.
If you want a creamier end result, adding 1-2 cups of sour cream is awesome. If you have picky eaters as I do, 1 cup sour cream and 1 cup of milk help to give the creaminess without all that tangy sour cream flavor that not everyone enjoys.
Yes, tuna noodles can be made and frozen. Simply assemble it as directed and let cool completely in a freezer safe pan. Then place the pan on a baking sheet and cover the top well with foil.

You can use cream of celery along with the remains ingredients and it goes off the charts !
I've never used cream of celery before, but I'm really intrigued! I'll try it next time since this is a regular dish in our homes already 🙂
