The first attempt I cooked too much pasta, second attempt was great! Instead of Feta I used Gruyere and I did mash the sweet potato to a smooth consistency before mixing in, so it looks closer to the boxed variety bright orange. I first found Nigela's original recipe in metric measures. Everyone loved it and it was voted a 'new staple'. New favourite recipe! The only alteration that I made was to add 2 or 3 Tbsps of Nutritional Yeast to the sauce (a genius idea by the way). This is excellent, it is a filling meal cheap to make, great for kids and adults.in fact I made it and blogged it. It added an element that cut the sweetness of the sweet potatoes. Finally clicked tonight when I didn’t bake it (we like our mac looser) and I added a few shakes of garlic powder. I’ve made this repeatedly with parmesan or Romano replacing the feta because it’s what I had on hand. I made a half batch of this with leftover mashed baked sweet potato, which made it very quick to put together. Next time I'll try sprinkling panko bread crumbs on top. Very forgiving recipe as long as you don't overcook the pasta. I used smoked paprika and added extra, stirred in chopped sage in addition to the topping, stone ground instead of English mustard, and a variety of cheeses I had on hand. Perfect comfort food on a cool fall evening. Perfect! The fresh sage was a great touch and my fussy little dude ate it.
