Here is a great little recipe video from our friends at Cucina Fanpage... Standing Rigatoni in a Mug. This version backs the mug in the oven, like an individual casserole. There is another version done in a microwave, but I prefer this baking method.
Click on the photo above to see the video.
If you want to see how to make a larger version for a large gathering, try our recipe, Torta Rigatoni Piede Bolognese al Forno (baked Standing Rigatoni with Bolognese).
