Super Creamy Tuna Casserole

I was tossing up today which recipe to share with you all, but since the weather has been so cold, wet and dreary in Sydney today, I thought I’d go with the “comfort food” option.

I made this tuna casserole last week and it went down a treat. I love an indulgent, creamy pasta bake every now and then and this one is a keeper, I think. I’ve shared a recipe previously for a three cheese tuna and veggie pasta bake, but this is a lot more simple to make as it doesn’t require you to make a sauce from flour, butter, milk and cheese.

Instead I use coconut milk and a little dairy cream, which are both already quite nice and thick without the need for a roux. I know coconut milk and tuna seems like a weird combination, but just trust me on this one! Once the cream, seasoning and cheese is added, you can’t even tell it was coconut milk. I love using coconut milk where I can because it’s loaded with good fats, so don’t be afraid of it! And make sure you use full cream, not any of that watered down light coconut milk! 


For the pasta, I used the brown rice macaroni noodles I bought last week. And as usual, I also loaded the dish with plenty of veggies! I’ve been trying to use silverbeet in more recipes, because I’ll be honest with you, I hate it. There. I said it. I just think it has a weird taste (especially the stalk  of it) and I usually can’t stand it. But I know it’s packed full of nutrients, so I’m giving it a chance in some different dishes. I ended up really liking it in this recipe. Maybe it’s because it was mixed in with cheese and pasta. That usually makes anything taste good, am I right?



All I had to do to make the sauce was sauté some garlic, sliced shallot and veggies, added the cooked pasta, tuna, coconut milk, cream, salt, pepper and stirred it altogether in a large pot. 




Then I stirred through a cup of cheese, poured it all into a baking dish and topped it with a little more cheese. 





The best thing about this dish is that it only took me about 30mins to make. The tip to getting it all done as quickly as possible, is pre-heating your oven as soon as you get in the kitchen, pre-boiling your pasta water in the kettle, and prepping your veggies and sauce while the pasta is cooking. If you do all that, you’ll be eating it by the half hour mark! Which is something I know we all look for after a busy/long day at uni or work.
