Cheesy Tuna Casserole

Is tuna casserole totally 1987?

Umm….oh well.

I guess I was born in the 80’s, so it’s sort of part of my generation? Or not?

I don’t know what I’m talking about. It’s all just gibberish.

Actually, this whole blog is sort of a mish-mash of gibberish. Albeit yummy gibberish.

That was a fun tangent.

Anyways, this tuna casserole is the freakin’ bomb. {I’m so modest.} I’ve made it twice in the last week, that’s how good it is! All 3 of us in my family CANNOT get enough of it which is weird because typically when we crave something, it’s usually like this or this. Who craves tuna casserole?

I’ll tell you who: This Girl. Right here.

Well, this here is a version of Tuna Casserole that will make your family FLIP out. This is seriously one of my new favorite casseroles and will probably stay at the top FOREVER.

Ok. Not really. That statement is true until I make some other casserole that becomes a new obsession.

Have I mentioned I’m addicted to food? Crullers and tuna casseroles. That’s how I roll, baby.

Wow. Yet another fun tangent for you people. {See? GIBBERISH, I tell you!}

So, yes. Back to my lover, Mr. Tuna. So tasty, so creamy, so cheesy, no one will not like this. Like that double negative? Oh yeah. The best part about this recipe? Only 1 pot needed and it’s ready in under 30 minutes. How’s that for a weeknight meal? Totally awesome. AND, the leftovers are totally rad too. My 3 year old requested this as her lunch the next day. Unheard of at my house.

Ready to make this? Get ready to be amazed…..not really.

First thing you want to do bring a large pot of water to boil and steal this pasta back from a certain thief.

I’m using Barilla Plus Farfalle. Cute little bowties that are perfect for casseroles.

You’ll also want to chop up a whole head of cauliflower into small florets.


One that water comes to a boil, throw in some salt and the pasta. Then after a few minutes toss in the cauliflower too. Once everything is good and soft, drain it all and set aside.

Place that same pot back on the heat and saute those diced onions in some olive oil. Once they are nice and soft, we can add in some salt, pepper and


a jar of alfredo sauce. Once you pour this whole thing in, measure out your milk and pour it into the dirty jar. Shake it up and add that milk in too. Cleaning out the jar, baby! Just another lazy step brought to you by Lauren’s Latest.

So, we’re also going to throw in a bunch of cheese to the sauce too. Cheesy goodness. OH YEAH. After a minute, all the cheese should have melted and the sauce should be good and creamy.

Now we can add in the drained tuna, the cooked cauliflower and pasta and the peas.


Stir this up to coat everything in that sauce and rejoice.

Flatten out the top and sprinkle with more cheese.

Throw this under a hot broiler for a few minutes to get the top brown and bubbly and that’s it! DINNER TIME!

    The first recipe that I would want to make is either this tuna casserole (if I don’t make it before next week!) or a shrimp scampi.

  2. Sarah L

    I would love to make a simple pasta with vegetables and a light balsamic sauce, sort of like Noodles and Company’s Pasta Fresca.

  3. Christy Landry

    Tuna Casserole of course. I SO want to like tuna casserole but haven’t found one that works for me. This might just do the trick!

  5. Patricia

    With the delicious recipe you have posted today, why would one look any further for a recipe to make with the Barilla winnings? Thank you for the recipe and the opportunity to win the pasta to make it with.
