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!
Outrageous pasta that happens to have a whole lot of cheese, a whole lots of veggies and even a little fish. Good eats, right here peeps.
My kind of dinner. Here’s the printable:
Enjoy your long weekend!

65grams of carbs is considered low carb?
I read through the recipe twice, but there was no mention of when to add the Tuna… It might be common sense, but for someone who has never cooked a tuna casserole, I am puzzled.
Got that added it 🙂 Sorry about that!
I was wondering if you could use green beans in place of the peas?

This is so good! I have made it several times. The printable recipe version does not tell you when to add the drained tuna (it is obvious when to do so but thought I should point that out).
Thanks for the recipe!!
I know this post is years old but I’ve had this recipe printed and am just setting it up for hubby to make tomorrow – two things.
Ingredients list 2 “cans” of tuna – what size?
I am subbing in shredded canned chicken from Costco and wondering if we should use one of the large cans or two.
Also in the printable directions it doesn’t indicate where to add the tuna. Luckily I now see it in the post itself.
They are the regular sized cans, not Costco cans.

Am I the only one who noticed that the instructions never mentioned adding the tuna?
I would leave out the pasta and add Lima beans and carrots or green beans for a lower carb content.
When do you add the tuna? Not in the instructions.
Thank you!
Susanne
I have made this and it is delicious!
I don’t mean to e rude, and I’m sure to been mentioned already, but this is loaded with and has a huge amount of carbs
This isn’t low carb -.-
How is this low carb?
Thank you for sharing this recipe. I will definitely make this low carb tuna casserole again. It has great flavors. I substituted zucchini zoodles for the Barilla, to reduce carbs further.
When do you add the tuna?
How many carbs /serving please
Your tuna casserole looks delicious. How many grams of carbohydrates per serving?
I follow you on Facebook
I’d make this! I already have it printed out.
Can someone please tell me the carb count for this?
Since this is a TUNA casserole, why did we forget to insert the word ‘TUNA’ in the directions section of the downloadable recipe?
I’m curious how this is low carb with the pasta in it. Do you know the breakdown?
May be good, but it is not even remotely low carb.
How can this recipe be “low carb”? There is PASTA in it! Does anyone have the nutritional break down for this recipe…..for 4 servings?

I follow Lauren on Facebook…If I win I will be making this recipe…Thank You…
you forgot to tell me when to put in the tuna….
The first recipe I would make is this cauliflower tuna casserole! Sounds Heavenly!!
Your recipe does not state when to add the tuna.
Can’t wait to try this recipe! I also will be making a Crab Mac&Cheese with the Barilla Plus. I must go follow you on FB now for more goodies! 🙂
when do you actually add the tuna in this recipe?
You forgot to put the tune in.
Low Carb Tuna Casserole !! It looks delicious .

I would make this tuna casserole.
can this casserole be frozen
I’ve never tried it, but don’t see why not. You might need to add a little more liquid so when its reheated, it’s the same consistency as when made and eaten immediately.
I follow Lauren’s Latest and Barilla on FB
The first recipe I will make is a Greek Patstisio – I have a weekday version I make and my family loves it. Looking forward to cooking!!!
