MiMi’s Creamy Tuna Casserole

Thanks for sharing!

Mimi’s creamy tuna casserole is different than most, there’s no pasta! It’s baked and served over rice to make a comforting Lent friendly meal.

Are you looking for a different way to turn a  couple of cans of tuna into a delicious meal? This yummy tuna bake topped with crunchy potato chips is flavorful and super simple. It could be served over noodles, but we always have it over rice with peas on the side. It is an economical meal this is sure to please.

This is one of those recipes my family grew up with. MiMi would make is several times throughout the year, but it was a Lenten dinner regular.

My dad would occasionally request it and we all enjoyed it. Recently my brother was looking for the recipe online and couldn’t find it, so of course we had to change that!

I hadn’t made it in several years, so it was fun to take our dinner table on a stroll down memory lane. And now next time my brother is looking for the recipe, he’ll be able to find it!

Now that I’m thinking about it, MiMi used to make a creamy tuna lasagna during Lent as well. I wonder is she still has that recipe too.

Tuna casserole without the noodles? 

Yes! This recipe has most of the ingredients you would expect in a tuna casserole. 

It has canned tuna, of course. Like most good casseroles, there is some cream of mushroom soup.

Once it is good and bubbly, you add bits of crushed up potato chips. A few more minutes in the oven and the salty, crunchy topping is perfect.

If you need the pasta to be happy, serve your bubbly tuna goodness over wide egg noodles. But of you want to serve it the way MiMi does, it goes over rice every time!

And the preferred if not only acceptable side dish is peas. If you are serving me, only fresh or frozen peas. 

Canned peas are nasty. There, I said it!

Now I know this meal isn’t the most photogenic. But that should not stop you from making it. Your taste buds won’t mind that it wasn’t beautiful.

Yum. I love a good tuna casserole and I do not mind a bit but the noodles are not in there, in fact, Mr. Nine would probably love this as you know he doesn’t like noodles, ha ha. The potato chips on top of the perfect crunchy and saltiness! Have a great weekend!

I forgot he doesn't like pasta. So strange! ;-) This would be perfect for him then!
