This pasta bake needs little introduction. It’s best described as the most delicious and nutritious macaroni cheese you’ll ever eat. A sort of macaroni cheese-verde. I use elicoidali pasta shapes, which are like a giant version of macaroni, making every mouthful extremely satisfying and substantial, covered in a thick homemade cheese sauce with finely chopped bacon, leeks and spinach. It’s very straightforward and wonderfully indulgent, perfect for an Autumn dinner.
