Slow Cooker Chicken Cacciatore is an easy crock pot meal loaded with tender chicken, tomatoes, bell peppers, kale, carrots and sliced mushrooms. Comforting and delicious!
Season chicken with salt and black pepper. Heat olive oil in a large non-stick skillet over medium-high heat. Sear chicken until golden brown, about 3 minutes per side. Transfer chicken to slow cooker. Alternatively, if pressed for time, skip browning and add chicken straight to a 6-quart slow cooker.
30 minutes prior to serving, stir in the olives, kale and cornstarch/water slurry into the slow cooker and cook for an additional 20-30 minutes on HIGH, or until sauce thickens up slightly and kale is wilted.
