Tuna mornay is one of my childhood favourites – whenever Mum said we were having this for dinner, I was stoked. I was one of five children, and this is a great recipe to feed a crowd. It freezes well too!
Preheat the oven to 180°C conventional (160°C fan-forced).
If you are making the breadcrumb topping, mix all the ingredients in a small bowl. Set aside.
Bring a large pot of water to the boil. Add the pasta and cook for about 8 minutes (it should be a little underdone as it will continue to cook in the oven). Drain, run under cold water and set aside.
400 g elbow pasta
Place the same pot over medium heat. Add the butter and let it melt. Add the garlic and whisk, then add the flour and continually whisk for about 2–3 minutes to cook off the flour. Add 1 cup of the milk and whisk continually for 1 minute, until it really thickens up. Gradually add the rest of the milk over 5–8 minutes, whisking in between additions (you don’t want the sauce to burn, so the whisking is important). Add the stock powder, onion powder, mustard and parmesan. Whisk until incorporated, then turn off the heat.
To the creamy white sauce, add the tuna, corn, broccoli and cooked pasta. Combine well and pour into a large baking dish. Top with the tasty cheese and sprinkle over the breadcrumb topping, if using.
425 g canned tuna, 400 g canned corn, 2 cups broccoli, 400 g elbow pasta, 1 cup tasty cheese, 2/3 cup panko breadcrumbs
Cover with foil and bake for 25 minutes. Remove the foil and bake for a further 10 minutes, until golden, crispy and bubbling.
