Recipe FAQ

What is the best way to prepare the chicken for this dish?

Use boneless, skinless chicken breasts placed directly into the slow cooker for even cooking and tenderness.

Can I add vegetables to this dish?

Yes, mushrooms and peas can be added for extra texture and flavor. Baby spinach is great in the last 30 minutes of cooking.

What type of pasta pairs well with this meal?

Fettuccine or linguine are ideal as their wide strands hold the creamy sauce nicely.

How can I adjust the creaminess of the sauce?

Use half-and-half instead of heavy cream and substitute Neufchâtel cheese to create a lighter sauce without losing richness.

Is it possible to cook this outside of a slow cooker?

While designed for slow cooking, a gentle stovetop simmer can work, but watch closely to prevent burning and adjust timing.
