This slow cooker chicken cacciatore transforms simple ingredients into a rustic Italian feast with minimal effort. The chicken thighs become incredibly tender as they simmer in a rich tomato sauce with colorful bell peppers, earthy mushrooms, and briny olives.
I discovered this recipe during a particularly busy season when my family needed comforting meals but I had little time to cook. The first time I served it over creamy polenta instead of pasta and my husband declared it his new favorite Sunday dinner.

I absolutely love how the kalamata olives transform this dish. My grandmother from southern Italy always insisted on adding them at the end of cooking to preserve their distinct flavor. The first time I shared this recipe with her she took one bite smiled and said it reminded her of Sunday dinners in Naples.
