Step 6

Remove the lid from the pan and add the heavy cream, Parmesan, and salt to the pan. Stir well to combine.

Step 7

Let cook, stirring often, until the sauce has thickened and the cheese has melted, about 3 minutes.

Stir the bacon back into the pot and sprinkle with red pepper flakes before serving.
