Prepare the Chicken:
Season chicken with salt, pepper, and optional Italian seasoning.
(Optional) Sear chicken in a skillet with olive oil for 2–3 minutes per side to add flavor.
Mix the Sauce:
In a bowl, whisk together chicken broth, heavy cream, minced garlic, and Parmesan until smooth.
Assemble the Crockpot:
Place chicken at the bottom of your crockpot.
Pour sauce mixture over the chicken, coating evenly.
Add uncooked pasta now, or cooked pasta later during the final step.
Slow Cook:
Cover and cook on LOW for 3–4 hours or HIGH for 1.5–2 hours, until chicken is tender and fully cooked (165°F / 74°C).
Combine & Serve:
If using pre-cooked pasta, stir it in at the end and toss to coat.
Top with extra Parmesan, parsley, or red pepper flakes.
(Optional) Broil for 2–3 minutes for a golden, cheesy finish.
