    This is a Huge hit in my household, my fussy daughter even eats it 🙂

  2. Andrew Fraser August 22, 2016

    This was really good ! I was a bit concerned it would have too much fluid in it but all that was absorbed by the pasta. Yum!

  3. So good. Demolished by my family of 2A and 3C aged 4 to 14. 5 hrs was to long for my cooker, 3.5 to 4 is more likely. Thought it would be salty, but wasn’t. Definitely will be done again (& again…)

  4. Made this the other night and invited my fiancées mum, brother and 4yo sister over, the 4yo DEMOLISHED her bowl and everyone asked for seconds, also served it with a salad. Such a hit in this household, I’m making it again tomorrow morning, setting the slow cooker on while I’m at work! Woohoo!

  5. What size is the cup you use please? This sounds delicious I can’t wait to try it out.

  6. Lise knight May 4, 2017

    Could I use normal milk in place of the cream / evaporated milk? ?

  7. I HATE Tuna with a passion….. Family luvs it tho. Decided to make this for them as I had no idea what I wanted to cook for dinner!!! I decided to try it to see if the pasta was cooked. OMG…. I cant tell you how much I devoured straight from the cooker!!!! Everyone luved it too. This stuff is pure heaven!!!! Wendy Herne you are an angel. This is now a once a week meal. Thankyou so much. I still dont like tuna but I sure do luv this! If i could give it 20 stars out of 5 I would!!

  8. Dannielle Palmer May 27, 2017

    If I make this and stir in cooked pasta at the end would I maybe use less liquid ingredients ?

  9. Does tuna have to be in brine or could it be spring water I have plenty of tims need to use

  10. Paula Jackman May 28, 2017

    This was so easy to make and very tasty, I will definitely be making this again.

  11. absolutely delicious,,,I used light carnation milk,only because that’s all had,,made no difference,,,delicious

  12. What can I use instead of canned soup? Stock maybe? Not a fan of canned soup.

  13. Awesome dish! Love it, fussy toddler ate two bowls. Next time I’m going to leave out water and tuna brine and cook pasta separately just to el dente and see how that turns out.

  14. Whole family loved it. Even fussy son tried it and said “Yum taste like chicken”. Quick and easy, ready in 3 hours on high.

  15. Quick and easy the whole family loved it. Making it again tonight. Fussy son tried it but said it tastes like chicken.

  16. Sue Collins April 1, 2018

    Made this for Good Friday lunch and it was so good. Really good flavour and very tasty. YUMMO

  17. Lovely dish better than I used to make. I used light condensed milk and tuna in springwater instead turned out awesome. Thank you to original poster.??

  18. Christine Damrow April 22, 2018

    This was so easy and tasty. I had to add a little more liquid later on in the cook as it was a little too thick to cook the pasta through and I would halve the cheese next time but was really good.

  19. Danielle Harris June 3, 2018

    This was absolutely delicious. My 5 and 8 year olds loved it too. I used a diced brown onion instead of the shallots and only needed 4 hours on low for me.

  20. Manda Van Niekerk June 18, 2018

    I’m not a tuna fan but this is delicious. A regular for me now.

  21. Lyndaanderson July 8, 2018

    My gosh I usually make a mean mornay . But this was delicious ???? I added some epicure cheese with the tasty…had a small chunk leftover in fridge and used vegeroni spirals. Cream instead of evaporated milk. Definitely make again

  22. Debbie White July 12, 2018

    this was really tasty, instead of cream and corn kernals i used creamed corn and it cooked on low for 2 hours glad i was home as it started sticking to the edge, but was a great dish

  23. We had this yesterday. I used cooking cream rather than evaporated milk, and cream of chicken soup rather than the mushroom.
    Added a good squeeze of fresh lemon juice when I added the cheese, which gave a lovely zing and also helped cut through the creaminess.
    Delish! Will definitely do this again!

  24. Coral Hastings September 21, 2018

    Definitely going to be a regular in my house now!!! Soooooo easy!!
    Both Hubby and 7 year old miss loved it.
    Used Cream of Chicken soup due to mushroom allergies and swapped the corn and peas to 2 cups of frozen mixed vegies, might add more next time 😉
    I just served it with some brown rice.
    Thankyou!!!!!

  25. Made it awhile back was great. Changed it up and did chicken bacon and mushroom instead of tuna. Sensational. Any one know the calories for the tuna recipe here

  26. Absolutely love this! I’ve changed the Mushroom soup to cream of chicken and found it much nicer to be honest! Yes mixing tuna with cream of chicken soup sounds strange but it totally worked a treat ??

  27. Tracy Hele May 28, 2019

    Unfortunately my pasta went glugggy, I used gf pasta, next time I will try it without and serve with rice. Had a lovely taste

  28. Linda Lee June 10, 2019

    Used chicken soup added cauliflower and brocoli as well had no carnation milk so used coconut cream was amazing did not need cheese due to the richness of the milk

  29. Cassie Brown August 8, 2019

    This was so easy and tasty, i used cream of asparagus soup as i love that flavour with tuna. My partner and our one year old loved it, plenty left over for lunch too. Will cook this one again, thank you

  30. Very tasty! Used cream asparagus soup instead of the mushroom, added a bit more corn and a pack of mixed frozen veges I wanted to use up to it. Big hit

  31. Jodie Deans February 4, 2020

    I cooked this last night and it was absolutely beautiful. Next time I’ll double the ingredients so we have seconds.

  32. Marlowe Howarth February 7, 2020

    This is one of my favourite recipes. I use mushroom soup as I am vegetarian.

  33. Jackie Raavel February 25, 2020

    We love this recipe but I did find that the pasta became very soggy when I added it at the beginning. I now add it about 45 minutes before serving and it turned out fine. I also add broccoli if I have some.

  34. Nancy Murphy April 26, 2020

    Love this recipe, have make it several time. My husband who is not a huge pasta fan also loves it. It is in the slow cooker for tonight’s dinner. Thank you Wendy a real winner ?

  35. Jodie Leemhuis May 25, 2020

    Outstandingly delicious! Super impressed with how scrumptious this recipe was ?? I made a few adjustments to suit our familys tastes – I used cream of chicken soup instead of cream of mushroom soup, added an extra 400mls of cream, 1 tsp of curry powder and a good squirt of mayonnaise. I added the pasta with 1hr to go, cooked on high for 3.5hrs in total. I also added a squirt of lemon juice when adding the grated cheese (as suggested in a previous review) and omitted the salt completely. Will definitely make this again,
    ? Great recipe Wendy Herne, thanks for sharing it ?

  36. Julie Buhagiar June 22, 2020

    I haven’t tried this yet but I’m definitely going to. When I was growing up mum use to cook this and I loved it but she use to add some curry powder and chopped up hard boiled eggs ??

  37. Paulene @ Slow Cooker Central June 23, 2020

    We partly doubled the recipe … double soup, double tuna, double water, double cheese, extra pepper (no salt) but stuck with 300ml of cream. I also choose to add pasta and shallots only for the final hour.
    It was a huge hit even with the two supposed ‘tuna haters’ who both had seconds hahaha
    Great family feed!

  38. Lauren Spackman June 24, 2020

    Super easy to make, used chicken soup instead of mushroom as hubby does not like that.

  39. Fantastic and super easy recipe.
    Love something that you can throw together with almost all pantry ingredients.

  40. Rachel Oliver September 9, 2020

    Love this recipe. Easy to prepare, makes heaps and can be easily adjusted. I add extra veggies, and use cream of chicken and corn soup which added an extra depth of flavour. Very tasty and makes alot. I usually pre cook the pasta first and then add it in. Personal preference.

  41. I made this last week. Got four meals out of it. I did freeze it, as I’m on my own, didn’t want to eat it four days in a row

  42. Super easy and YUM! I doubled the recipe and used evaporated milk instead of cream, I also changed the mushroom soup to cream of chicken due to personal preference. I didn’t add the pasta and shallots until the last hour after reading some of the comments left before and it turned out perfectly not soggy at all. My 13 year old daughter who doesn’t like Tuna ate it, and then overheard me talking and she goes WAIT there was Tuna in that haha GOOD BUDGET AND FILLING DINNER

  43. Chris Cherry ? everyone calls me Nanna which I love ??..l July 12, 2021

    Made this last night for dinner, absolutely the best I have ever had, thankyou Wendy Herne for sharing your amazing creation so easy and delicious. Hubby said awesome, let’s have it again soon ??

  44. Kaye Case July 29, 2021

    Cooked it yesterday. It did burn on the edges so I will try 4 – 41/2 hours next time. Delicious.

  45. Danielle Harris August 7, 2021

    My 3 kids that range from 11 to 3 loved this dish. They went back for more and more until it was all gone. I used a brown onion diced instead of shallots as I like the crunch they add. Definitely will be a regular in our house.

  46. Cooked this for the first time, really enjoyed it! Was a total winner in my house for hubby and 2 kids.

  47. I made this tonight, very simple and tasty. Will certainly do this one again

  48. OMG! OMG! OMG! Sooo yummy & sooo delicious! ?
    Made a few adaptions.
    Used cream of chicken soup, creamy carnation milk, 1 pkt Continental tuna mornay pasta bake, no onion, 2 cup water, all other ingredients as is. Added the pasta in the last hour.
    All had seconds & empty plates all round!

  49. Cathryn Pawley November 15, 2022

    5 stars
    Delicious and so versatile, with ability to tailor to what’s on hand without detracting from the great taste
    Have made it twice now, 1st time using the high fibre pasta which disintegrated ( but I actually loved it and used it again), also added a block of cream cheese
    Next batch will try cream of asparagus soup and add more veg to offset the cream cheese
    A really great dish
    Thanks

  50. Made for just the kids, but was hands down a Big winner for dinner last night. Miss 6 and 7 went back for more. Best tuna Mornay we’ve had mum, thanks! ??

  51. Jackie Raavel June 27, 2023

    I often add left over cooked chicken instead of the tuna. I mix all the other ingredients together except for the cheese & pasta & cook for an hour or so before adding the chicken (as chicken is already cooked it won’t need the full cooking time). I add the pasta about 3/4 hour before serving & then add the cheese. Love this recipe.

    1. Paulene @ Slow Cooker Central June 29, 2023

      The cheese type is listed “tasty” cheese. You can buy that specifically at supermarkets (or use a cheddar)

  52. 5 stars
    This recipe was really easy and worked out so well.
    I used “gluten-free” pasta and it still worked.
    Family asked for me to do it AGAIN!

  53. This is one of my faves and I make it frequently, but over time have tweaked it to make it healthier. This is where I’ve landed, still really creamy and tasty but healthier:

    1 can cream of chicken soup
    1 can cream of celery soup
    1 large can of tuna including liquid
    1.5 cups wholemeal pasta
    1 cup frozen peas
    1 cup frozen corn
    1 cup water

    Still 4 hrs low

    I tried this recipe for the first time today and it was absolutely delicious. So quick and easy to prepare and cook in one pot. As I used Tuna in Springwater I added a desset spoon of Vegeta stock powder. I doubled the recipe except for the cream (only used 300 mls) I cooked for 4 hours on low adding the pasta after 3 hours and it was cooked beautifully after the final hour. I needed to add about half a litre of milk when I added the pasta to make sure I had enough liquid (I added 500 Grams Penne)
    Very popular with the whole family. Will definitely make this again. it was so yummy.

  55. I’m at work for 8 + hours during the day, would this be ok to leave on low for that amount of time?

    1. Paulene @ Slow Cooker Central May 19, 2024

      No that would be too long for this one Julie
      But maybe make it on your weekend or days off instead 🙂

  56. What size slow cooker please?
    If you double the recipe do you still use the same time or would you need to increase the time?

    1. Paulene @ Slow Cooker Central May 22, 2024

      I would think at least 5L size
      No extra time for double Jenny

  57. 3 stars
    I didn’t have any evaporated milk etc so I left it out. There was still plenty of liquid so I added 1 cup of macaroni and turned my SC on to sear for the last 10mins. It turned out fine and was so easy but I must say I prefer the original way of cooking Tuna mornay on the stove with bechamel sauce.

    1. Paulene @ Slow Cooker Central June 7, 2025

      That’s the best kind isn’t it Helen! 🙂

  58. Kerry Brown August 26, 2025

    Easy quick midweek, cooked pretty much in two hours on high. I then added the cheese and turned to warm for an hour.

  59. This was absolutely delicious, it was also so quick and easy to put together as well. The only thing I would change next time is that I would double the recipe as my kids loved it and kept coming back for more.

  60. 3 stars
    I don’t think the pasta needs 5 hours to cook. It went gluggy. I think I will add it half way through next time.
    Otherwise it was a tasty dish.

  61. 5 stars
    Absolute hit in our house. we will definitely be making this one again. Used 2 cups of frozen peas and corn, red onion instead of Shallots and a combination of light cream cheese and cottage cheese instead of evaporated milk/milk. Next time will add some baby spinach.

    1. Paulene @ Slow Cooker Central March 22, 2026

      Thanks for leaving the fab review Michelle! Really appreciate it 🙂 🙂

  62. Christine Bartlett May 3, 2026

    so easy and tasty, today i gave over the cooking and reading instructions to our 8 and 4 year old grandsons (with my supervision) they were very impressed helping to make this meal but enjoyed eating it even more lol, I add a diced brown onion, and use the tuna in spring water and a can of drained diced pineapple pieces 😀

    1. Paulene @ Slow Cooker Central May 4, 2026

      What a great experience for the grandkids!! Love this 🙂

  63. 5 stars
    Wow what can I say this was so very yummy . My son and partner aren’t big on eating Tuna . But they both went back for seconds and said please make that again . It’s a 10/10 in our house thanks Pauline another great recipe of yours 😃

    1. Paulene @ Slow Cooker Central May 8, 2026

      This is Wendy’s amazing recipe Relle – but I’m sure she will be thrilled to read you loved it! 🙂

  64. Ally hayton May 13, 2026

    eating this now
    I swapped the mushroom soup to cream chicken ( on Pauline’s advice) and its brillant will not cook in oven again delish

  65. 5 stars
    This was a HUGE hit in my house. Hubby said it tastes just like his mums did when he was growing up. Kids asked me to make it again!!

    1. Paulene @ Slow Cooker Central June 2, 2026

      Fabulous 5-star feedback – Thanks Dayle! 🙂
