If you love mushrooms, I recommend using shiitake because they are so wonderfully flavorful.

Or you could augment creminis with dried porcinis that have been reconstituted in hot water.

Place half of the pasta in an even layer in the casserole dish.

Cover with half of the sauce.

Dot the sauce with all of the ricotta cheese.

Sprinkle half of the Mozzarella over the ricotta layer.
