Tips
Use cast-iron grill pan for even searing and heat retention when cooking chicken.
Do not skip whisking flour into butter smoothly to avoid lumps in the sauce.
Add cream slowly while whisking to prevent breaking the sauce.
Good to Know
Refrigerate sauce and cooked chicken separately in airtight containers for up to 3 days. Reheat gently on stovetop with splash of cream.
Cook chicken and prepare sauce up to 1 day ahead. Reheat separately and combine with fresh-cooked pasta before serving.
Serve immediately while sauce is warm and creamy. Garnish generously with Parmesan and fresh parsley.
Common Mistakes
Do not overcook chicken to avoid dryness; use meat thermometer and remove at 165°F.
Do not add cream too quickly to hot roux to avoid lumpy sauce.
Do not skip covering pasta to avoid it drying out while you prepare the sauce.
