Bring 4 quarts of water to a boil in a large (6-8 quart) pot. Season with salt and pasta.

While the pasta cooks, cut the butter into 1-inch cubes and set aside to soften.

When the pasta is done to your liking, drain it in a colander, reserving 1/4 cup of the pasta water. Return the drained pasta to the pot and stir in the butter, half of the grated cheese, and half of the bread crumbs. Toss and coat thoroughly. To moisten, add the reserved pasta water. Season with freshly ground black pepper, if desired.

Transfer to a serving bowl or individual pasta bowls and top with remaining cheese and bread crumbs. Serve right away.
