Can I use frozen chicken breasts?
For food safety, it is best to start with thawed chicken in a slow cooker. Slow cookers can take too long to bring frozen chicken to a safe temperature. If you only have frozen, thaw in the fridge overnight first.
How do I keep chicken breast from getting dry in the slow cooker?
Use enough liquid, keep the lid on, and do not overcook. Chicken breast is lean, so it benefits from a shorter cook time. Start checking early, especially if you have a newer slow cooker that runs hot. Pull it when it hits 160 to 165°F, then let it rest a few minutes (it will finish cooking as it sits) and return it to the sauce.
Can I use chicken thighs instead?
Yes, boneless skinless thighs are even more forgiving. Cook time is similar, and the sauce will be extra rich.
Can I make it dairy-free?
Yes. Swap the cream of chicken soup for a dairy-free condensed soup. Or skip the soup entirely and use an extra 1 cup broth, then increase the cornstarch in the final step to 3 tablespoons (still mixed with cold water) to thicken the gravy. Replace sour cream with a dairy-free alternative, or skip it and finish with a squeeze of lemon for brightness.
My gravy is too thin. What do I do?
Stir in a cornstarch slurry and cook on High for 10 to 15 minutes. Keep the lid on for best heat, then check. If you still want it thicker, cook another 5 to 10 minutes. You can also simmer the sauce in a saucepan until it thickens.
My gravy is too thick. Help.
Easy fix. Stir in a splash of warm broth a little at a time until it is spoonable again.
