I grew up on this classic Tuna Tetrazzini Casserole.  Elbow macaroni, mushrooms, and albacore tuna in a slightly tangy sauce. We love it topped with crunchy potato chips!

I know, I know… Tuna Noodles is probably one of the easiest things in the world to make, right?  Well, it seems that every time I think I shouldn’t blog about something that seems to boring or simple, I am surprised at the response it gets. 
This post originally went on my blog about 5 years ago.  My website has grown so much over those 5 years, and it was time that this classic casserole got a face lift!

When my kids were little and they asked what was for dinner, and I answered Tuna Casserole, they always asked “Where are you going tonight?”  It is my usual fall back for making something ahead that is easy, everyone loves, and I can put it in the oven and skedaddle out the door! 
So, when they ask and I am at home they are surprised.  Nice to keep them on their toes. Not to mention, I get to enjoy one of the meals I loved when I was a kid.  You see this is my Mom’s recipe, and when I make it, there are rarely ever leftovers. My family devours it!!


Ingredients in Tuna Tetrazzini:

  • elbow macaroni
  • cream of mushroom soup
  • canned mushrooms
  • lemon juice
  • parmesan cheese
  • salt & pepper
  • potato chips


Do I have to use elbow macaroni?

Nope! This recipe is one I sometimes just use up what I have one hand.  You might get a mixture of elbows noodles, penne and bow tie — you just never know!  

Can I add in other things?

Sure! Make it your own! I love it with sliced black olives, but not everyone in my family likes olives. 

They all love it with peas.  My Mom used to put peas in it sometimes, canned ones.  Gak!!  Guys.  Unless it’s a snow pea or a sugar snap pea, I just can’t do it. The frozen ones aren’t as bad — but the canned ones?  No thank you.  But hey — you do what you  want to your casserole!  

Not a fan of creamed can soups?  I know some people are weird about them.  You can always make your own Condensed Cream of Mushroom Soup

My Mother-In-Law puts cubed up pieces of cheese in hers.  You can always add cheese to the inside or melt some on the top in place of the potato chips.

I love using fresh cracked pepper, but use what you have on hand.

I have to tell you a quick story about the potato chips on top.  To me, those really just make the casserole.   About 2 years ago, I got a new oven.  It has a Rapid Preheat feature.   I always use convection when I bake, so that cooks with a fan, right?  Well, not when it rapid preheats!!  So, I was in a rush — turned the oven on, and popped the casserole inside.  A little later I happened to glance at the oven, the light was on inside, and the whole thing was full of smoke!

I opened the door and black smoke rolled out.  The potato chips were ON FIRE.   You know when a campfire is smoldering?  The coals are black and orange, and there is that little bit of flame here and there?  That was my casserole.  So — we ordered a pizza and I have never put anything in my oven when it was on rapid pre-heat again!
