Recipe from Nigellissima.

Pasta and Potatoes together in one dish? Yes please!
I’ll start with the outcome… Devine! I did as advised and ate this the day after making having been blitzed in a hot oven, and it was wonderful. The pasta crisp at the edges with the cooked potato and creamy-cheesy sauce within is a textural and taste delight.
The combination of the meal isn’t too hard either, it acquired more washing up than I’d hope for a meal just for me, but totally worth it for the result. Will definitely be making this one again, a pretty great cosy night staple.
