Tuna Casserole

Easy, bright, fluffy, and super flavorful tuna casserole recipe!

I grew up loving tuna sandwiches. I don’t know what it is about it…I just did. I could even smell it from quite far away …. but then again, it’s fish, so anyone could. My dad was the only other person in my family who enjoyed tuna. When I went to college, a roommate of mine boiled some egg noodles, poured tuna, sour cream, and peas in the pot and mixed it all up. I was intrigued. I had never had anything like it and I loved it! She told me it was a simplified version of tuna casserole. So, I came to love tuna casserole!

As an adult, I made tuna casserole (as an actual casserole) many times. Justin doesn’t like tuna or sour cream. But, he’ll eat my tuna casserole. And, Rhys really enjoys it (it has his favorite vegetable–peas!). So, just like C4, it’s one of our staples. So, I figured, it’s been long enough that I need to put the recipe on the blog!

My absolute favorite part of the casserole are the edges and the especially the corners. It gets crispy and allows the potato chips to take the main flavor. Easy and super flavorful tuna casserole recipe! But, I also love the exact middle and “slurping up” the noodles–the sour cream really brings out the flavor of the tuna! I love the “almost burnt” crunch! Rhys loves the peas–sometimes he’ll pick them out. But, the biggest surprise is that Justin (who doesn’t care for tuna alone or sour cream) wants seconds!

This is a staple now in our family. Last time we had it, Evelyn just stared at it. I gave her a tiny piece of chip and her face was so funny when she got the vinegar flavor!

  1. I don’t think I’ve ever had tuna casserole! I don’t think I’d like this one because I imagine the fat macros are really high (sour cream & chips), but it sounds delicious and tuna is SO good for you that it might still be worthwhile.

    1. Tuna is absolutely delicious! Sometimes, I’ll have plain tuna,..no mayo or anything…on top of Wasa crackers. Or, I’ll mix it with poppy seed dressing. I also love making tuna salads…romaine lettuce, shredded cheese, tuna, peas, tomatoes, and poppyseed dressing.

  2. This looks delicious!!!! Thanks for sharing. Will definitly be pinning to my need to make this Asap list.

  3. It does sound really good! We like tuna noodle casserole in my house. I would just have to make it with fat free sour cream, cheese, and baked chips, but I think it would still work.

    1. Typically, I buy fat free sour cream, too….to be honest, I can’t tell the difference in taste, so why not go fat free?

    1. Definitely very easy to put together. And, you can also put it all together and not cook it…just put it in the freezer for a long/hard day when you don’t feel like cooking! Then, just pull it out and heat it up!

  4. Oh my, this sounds and looks delicious!! 🙂
    Thanks for sharing the recipe!

  5. This was one of my favorite dishes growing up! May throw it into the lineup now!

  6. I don’t make casseroles nearly enough. But they are so good! I will definitely try this!
