Most important ingredient: a cute kid to make 'em with!
First, cook the pasta and drain it thoroughly.
Preheat the oven to 400°.
Spread the olive oil around a 3-quart baking dish.
Mix the pasta and the sauce together.
Then, add the ricotta cheese. (You just want it to be partially and unevenly blended in.)
Put the pasta in the baking dish.
Cover it with mozzarella cheese.
Bake for 25 minutes, or until the cheese is all melty and spotty brown.
Serve with Parmesan cheese, and enjoy!
