Tuna Mornay is how you elevate canned tuna above a glum pantry staple or worse still, a desperate meal eaten straight from the can! It’s a tuna casserole pasta bake with a creamy sauce, sweet pops of corn and crunchy topping, baked until golden and bubbly.
Simple to make, economical and oh-so-delish!

Tuna Mornay
I moved out of home straight after finishing high school at the tender age of 18, so it will come as no surprise to you that I had my fair share of meals comprising canned tuna in various, completely unappetising forms. Dumped into rice, on pasta, on toast (with melted cheese!) and the worst offender of them all – eaten straight out of a can.
Which, nowadays, is more acceptable with the dizzying array of flavours available – chilli, lemon pepper, Portuguese.
Back then, it was not. 😂
I’m glad I’ve evolved beyond that. Canned tuna can be used in all sorts of delicious ways – and this Tuna Mornay pasta bake tops the list!

What is Tuna Mornay?
Tuna Mornay is the Aussie name for a tuna casserole pasta bake made with canned tuna and pasta in a creamy white sauce. There’s various forms of add ins – often corn, sometimes peas – and it’s topped with something crunchy. A parmesan breadcrumb topping is my favourite, but there are versions “out there” with crushed cornflakes, crispy fried onions and even potato crisps. (Yes, really, google it)

What you need for Tuna Casserole
Here’s what you need:
![What goes in Tuna Mornay (Casserole / Tuna Pasta Bake)](https://recipetineats.com/wp-content/uploads/2019/11/What-goes-in-Tuna-Mornay-Pasta-Bake.jpg)
Just a note on a few of the items:
Vegeta stock powder / granulated bouillon / seasoning (same thing!!) is the secret ingredient here that makes the white sauce extra tasty. It’s salt – with flavour. I like using Vegeta, which is a Vegetable stock powder (herbs & spices aisle of everyday grocery stores!). Read more here about Vegeta here (including MSG misconceptions & what else to use it for!)
Tuna – tuna in oil is tastier (full stop!) but spring water or brine is fine too; and
Corn (and other veggies) – peas and corn can be added uncooked and even frozen straight into the dish. For things like diced carrots (frozen or fresh), I’d recommend cooking them first as they won’t cook in the bake time for this recipe. I just use corn – because it’s the classic add in.
![How to make Tuna Casserole (Tuna Mornay Pasta Bake)](https://recipetineats.com/wp-content/uploads/2019/11/How-to-make-Tuna-Mornay-Casserole-Pasta-Bake.jpg)
Melt butter, mix in flour, then whisk in milk – the flour will make the sauce thick and creamy;
Add in parmesan and other sauce flavourings (including our secret ingredient, Vegeta);
Flake the tuna into large-dish chunks so it doesn’t turn into mush when you mix it through, then mix it all up together;
Tip into a baking dish, top with crunchy Panko-parmesan topping and bake until it’s golden on top and bubbling on the edges!
And here’s an up close and personal of what’s under that crunchy golden topping. Love that creamy sauce!

What to serve with Tuna Mornay
Unless you load it up with more extra vegetables (it can take about 2 cups extra AND you can sub some of the pasta for more vegetables), I’d recommend some veggies or a crisp salad on the side – just to complete the meal! Here are a few suggestions:
Veg and salad side suggestions
Otherwise, make up your own garden salad or steamed vegetables and drizzle with a quick Balsamic Dressing, French Dressing or Italian Dressing.

- 2 tsp Vegeta, or chicken or veg stock powder/granulated bouillon (Note 1)
- 1/2 cup (50g) parmesan , finely shredded
- 1/2 tsp each mustard powder, onion and garlic powder (Note 2)

- 1/2 cup (60g) panko breadcrumbs
- 1/4g (25g) parmesan , finely grated
- 1/4 tsp salt
- Chives or parsley , optional garnish
Instructions
- Preheat oven to 180°C/350°F.
- Crunchy Topping – Mix together.
- Cook pasta per packet directions MINUS 1 minute. Drain then allow to cool slightly, then return into pot.
- White Sauce – Melt butter in a large pot over medium heat. Add garlic and cook for 30 seconds.
- Add flour and stir into melted butter. While whisking, gradually pour in about 1/3 of the milk. Once the flour-butter mixture is incorporated into the milk, pour in remaining milk and whisk.
- Add Vegeta, mustard, onion and garlic powder, whisk.
- When the milk starts to heat up, whisk constantly to make sure the white sauce doesn’t catch on the base.
- After 4 – 5 minutes, the sauce should be thick enough that you can draw a path across the back of a spoon (see video). Remove from stove and stir in parmesan.
- Assemble & Bake – Add tuna into pasta and flake into large chunks with fork (not too much, don't want it to turn to mush when stirred). Add corn, pour over sauce, then gently stir.
- Scrape into baking dish, top with Crunchy Topping.
- Bake 25 minutes until top is golden and edges are bubbling. Sprinkle with chives if desired then serve!

Life of Dozer
Dozer Does Melbourne – An assembly line of dumpling makers got a fright when he jumped up and slammed his heavy footed paws against the glass window!!

A hit in my house! I wanted to use the whole 500gram bag of penne instead of the 375 asked for, was worried it would end up too dry so I just made 1 and a half times the sauce (eg 1.5l of milk instead of 1l). Turned out so yummy and sauce ratio perfect!!
The best tuna bake ever.
Really good casserole,,,,easy to make…..an I even forgot the parmesan at the end….Everybody loved it…:)
Fantastic tuna bake . Full of flavours and the best ever. Receive produces enough for 6 adults.
We grow up with tuna pasta bake, but we would add pineapple instead! It’s my husbands favourite.
I forgot the Parmesan in the sauce so sprinkled a little extra on top and it still turned out 10/10! Love all of Nagi’s recipes. I don’t even look at recipe bases from the supermarket anymore, the recipes on here and in the cookbook are 100x better and not much more effort (plus I feel like a chef making them)!
Quite good. Only need 3 tablespoons of flour though.
MM
I assumed all tuna mornay recipes had diced boiled egg, Turns out it must have been a strange family recipe ha! I look forward to trying this recipe 🙂
Nope, we are weird too 😝 It’s in the oven now with sliced boiled egg on top. Thanks Nagi, pretty sure 6 out of 7 meals weekly are yours in our home 🥰
Love this recipe! Over time, I have made a couple of minor adjustments. I 1.5x the sauce as I like my mornay a bit saucier. Instead of mustard powder, I use 2 tsp of Dijon mustard. On top of that, I use an additional 1/2 tsp of onion & garlic powder & Vegeta (but you can do that to taste at the end). Absolutely delish and highly recommend!
So good, added some cooked risoni and added mashed potato on top with grated cheese

Made this a while back but forgot to rate it, my partner said it was better than M&S specials :D, I told him off for even comparing ready meals to home made. Anyway, I hope you and Dozer will be very happy in your new home, don´t know why I felt some kind of sadness when I saw the picture of your empty house, I would do a lot to have such a beautiful home and view, bet your next news will be that you´re engaged 🙂 x
Simply amazing!
Very accurate recipe and turns out well and very delicious. I had frozen mixed vegies added in there (peas, corn and carrot)
This was nice and a easy as I already had all the ingredients. I used frozen peas and beans instead of corn and spread grated cheese before adding the crunchy topping.
I made the Tuna Mornay as per instructions. Mine was a little dry, especially compared to the video. First time I’ve ever made a white sauce. Left it on the bench for 15 min as too hot for elderly. Obviously moisture was absorbed.But how can I save the rest of the dish???
Was very tasty though.
Kids loved it, so its a winner for me! Delicious.
I include the juice of a lemon and lemon zest, and make my own larger breadcrumbs (about 1cm square) by slicing up leftover bread crusts (freeze them until you have enough to cover the dish). low-fat grated cheddar cheese inside and on top of the breadcrumbs to brown slightly. Awesome!
Amazing. This recipe takes Tuna casserole to the next level. Yes I did add a pinch of chilli.
Made the Tuna Pasta Bake for dinner while wife and a friend went shopping. Best we all have ever had everyone loved it. Also used the Cucumber Salad and Carrot with Onion Salad as suggested by Nagi. Just wish i could do it as easy as the Video. Thankyou Nagi
