1

Let the pasta sit at room temperature until it becomes pliable, about 10 minutes. Meanwhile, heat the oil in a nonstick skillet over medium heat.

2

Add the prosciutto or bacon (if using) and cook until crisp. Transfer to a paper towel-lined plate.

3

Drain off and discard all but 2 teaspoons of the drippings in the skillet. Sprinkle the red pepper flakes (if using) over the remaining drippings.

4

Increase heat to medium-high. Add the pasta to the skillet and gently spread it out to form a large nest. Cook, without stirring, until the pasta begins to crisp and brown on the bottom, 4 to 5 minutes.

5

Sprinkle with the Parmesan and prosciutto or bacon (if using). Cook, still without stirring, for about 2 more minutes. Season with the salt and black pepper.

6

Slide or invert the pasta onto a plate and sprinkle with additional Parmesan. Cut into wedges, if desired.
