Step 1

Cook pasta in boiling water until al dente.  During last 5-7 minutes of cooking, add frozen peas and continue boiling both the pasta and frozen peas for 5-7 more minutes.  Drain.  Reserve 1/2 cup pasta water.

Step 2

Tear prosciutto into smaller pieces.

Step 3

In a large skillet, heat 2 tablespoons butter on medium heat. Add the torn prosciutto and stir to coat it with butter, for about 1 minute.  Add black pepper.  Add another 2 tablespoons of butter and stir until melted.

Step 4

To the skillet with butter and prosciutto add drained cooked pasta with peas.    Sprinkle 3/4 cup shredded Parmesan cheese evenly over pasta.  Stir everything together on medium heat until the cheese melts.  If needed, add a small amount of pasta water (about 1/4 cup) - but you might not need to.

Step 5

Season with salt, if needed.  Serve immediately, topped with the remaining 1/4 cup shredded Parmesan cheese
