Tips
Alternate noodle direction when scattering to minimize clumping.
Do not use pressure cooking or steam setting for the final 5 minutes to avoid overcooking shrimp.
Good to Know
Refrigerate in airtight container up to 3 days. Not recommended for freezing due to cream-based sauce and texture of reheated shrimp.
Prepare mise en place and measure all ingredients. Do not cook ahead; best served immediately after assembly.
Serve immediately while hot. Garnish with fresh parsley and additional Parmesan if desired.
Common Mistakes
Do not skip the alternating noodle scatter to avoid clumped, stuck pasta.
Do not use the steam setting or pressure cook during the final 5 minutes to avoid overcooked, rubbery shrimp.
