Can I use frozen chicken breasts?
Yes, frozen boneless, skinless breasts work in a slow cooker; add 30–45 minutes to cooking time and ensure they reach 165°F internally.
Can I make this dairy-free?
Substitute alfredo sauce with a dairy-free version and use dairy-free cheddar cheese, though texture and flavor will differ.
How long does it keep?
Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat gently on the stovetop with a splash of cream or broth.
Can I scale this recipe?
Yes; double the chicken and sauce ingredients for a larger slow cooker, but keep spaghetti proportional to liquid (add cooked pasta just before serving).
What temperature should the chicken reach?
Internal temperature must reach 165°F (74°C) at the thickest part for food safety.
