This is voted the Top 5 Thermomix family dinner recipe by my kids. I always have to double the recipe otherwise there’s arguments. The only recipe sub i make is to use frozen peas and corn mix. Thank you for the many years of having this quick and easy popular recipe at hand. It’s a real winner!

I was looking for a isolation friendly salmon mornay and came across this recipe. Im not usually a fan of salmon mornay but this was a hit! Everybody loved it, the only problem according to my husband was that there wasnt enough left for seconds :)

I made this tonight! I grew up with this dish...has to have the crisps on top!
I swapped corn for peas - simply because I'm the only one in our house that eats corn!
Everything worked perfectly - delicious to boot!
Only thing...and this may be my mistake? The lemon flavour was quiet strong, i zested the whole lemon...is this correct?
Thanks again for taking me back to my childhood.

  Hey Narelle, pleased to hear you enjoyed an old childhood favourite. The whole lemon zest is correct however all lemons can vary considerably in their taste of the zest and the amount of juice they all have. So I'm thinking you had a particularly strong one. Hopefully next time your lemon won't be as strong. :)

I used evaporated milk instead of regular milk. Beautiful and creamy.

Hi Rebecca, sorry I really can't advise as I haven't used gluten free pasta with this recipe. I'd still be tempted to try it if you are not making dinner out to impress guests! lol! Do let me know how it goes. :)

Quick and easy meal on the table within 1/2 hour, now that’s my type of meal!
Didn’t have mustard powder, so used 1 tsp Dijon mustard and it turned out just as nice.
Big thumbs up 👍

Really annoying that you don't mention removing lemon zest and cheese after blitzing them, somthey form part of the sauce from the beginning... when I realise down they should be added later, I stopped trusting the recipe and did it my own way.
It might seem like common sense and I did wonder, but since the zest and cheese instructions instructions were no different than for the onion, I proceeded. Most recipes make these things very clear so I guess I've allowed that to influence me.

  Hi Ali, I'm sorry that you got confused with the recipe. In step 3 it does say to set aside which means remove. Then in step 9 half of the cheese and zest gets added back into TM bowl, then the remaining half is used in step 11 combining with the crisps. I hope it was a meal enjoyed by you.

Wondering if this could be frozen in ramekins before putting in oven? Helping to stock my elderly in law's freezer as they love tuna Mornay and this sounds divine!

Made this for dinner for hubby and myself. The absolute BEST Tuna Mornay we have tried. Loved it - and will make it a staple in our household. So easy to make. Husband asked what was making it crispy. I told him it was his last packet of potato crisps. He thought for a moment, and said, yeah it was worth it. Thanks Leonie for another great recipe.

this was so easy, and so delicious. I didn't have potato crisps for the topping so I used pretzels which I chopped at the beginning. I love the crunchy texture. A quick easy dish when you need dinner on the table in a hurry :-)

This is a very quick and simple recipe, so simple that my husband was able to make it last night as I had to work late! A good standby to remember when I'm trying to think what to cook for dinner!

Great recipe! I made Chicken Mornay tonight using this recipe as a guide, swapping out the tuna for about half a roast chicken, chopped roughly. I didn't have any mustard powder or potato crisps on hand so I replaced them with American mustard and wholemeal breadcrumbs. I also left out the lemon.
After adding the milk to the onion/flour/mustard, the mixture became thick fairly quickly so I ended up adding about 100ml of veg stock once the macaroni was added. Next time I'll just use a little less flour and/or keep the MC on while cooking the onion - a fair bit of steam had escaped while cooking this bit. Will definitely make this next time using tuna - no doubt it will quickly become a family favourite.

This is a lovely recipe! Made it tonight and will definitely make again! Didn't have chips for the topping but used Panko breadcrumbs! I had used a wee bit more cheese only because I grated what I had left in the fridge! I didn't have corn so substituted peas and used Dijon mustard as I didn't have dry mustard. All in all very happy with your recipe! Thank you for sharing!

Made this last night for hubby & I. Very good, right amount of flavour from the lemon. Made the topping out of cubed wheat bread mixed with fresh herbs a splash of oil and the remaing cheese. Will be making again

Hi there. I made this recipe tonight and it was fantastic!! I have been doing Weight Watchers for almost a year now and so I adapted it to make it a little more WW friendly, and it was just amazing. The kids gobbled it all up! I'm really glad I found this page, I am not terribly adventurous with my cooking so I need very clear instructions but was started to get a bit bored with the EDC. Thanks again!

  Thanks Alice - I would be keen to hear how you made it WW friendly - I'm sure others would too. No doubt the potato chip topping had to go! ;)

    Yes, unfortunately the chip topping had to go. In order to make it a WW recipe, I used 50grams of light cheese in total. Instead of the chip topping I used a quarter of cup of wholemeal bread crumbs and I used a bit less tuna. Next time I will use about half the tuna. I also used skim milk not whole. I divided it into six portions (although the kids had seconds) and based on this, it came to 6 propoints per serve. A great nutritious and super yum dinner :-)

must have done something wrong as not enough liquid to cook pasta, might cook pasta separate next time and add it with the tuna. Added extra onion, cheese and milk, also added salt, pepper and smokey paprika. It made heaps.

  oh that's a shame Justine. I actually made it again last night and it was perfect. I wonder if your extra onion and cheese made the difference?
