Preheat the oven to 400 degrees.2.
In a large bowl, microwave the milk at HIGH for 1½ minutes. Melt the butter in a large skillet or Dutch oven over medium-low heat; whisk in the flour until smooth. Cook, whisking constantly for 1 minute.3.
Gradually whisk in the warm milk and cook, whisking constantly until thickened, about 5 minutes.4.
Whisk in the salt, black pepper, shredded Gouda and Gruyère cheeses and red pepper if desired, until smooth; then stir in the cooked pasta. Add the chopped prosciutto and mix well. Spoon the pasta mixture into a lightly greased 2-quart baking dish; top with the shredded Parmesan cheese. Bake for 20 minutes or until golden and bubbly.
