In a large skillet over medium-high heat, heat 1 tablespoon oil. Add chicken, season with salt and pepper, and sear until golden, 3 minutes per side.
Meanwhile, in a large slow cooker, combine potatoes, bell pepper, broth, cream, Parmesan, butter, and spices. Season with salt and pepper, then place chicken on top.
Cook on high for 3 to 4 hours or on low for 6 to 8 hours, until potatoes are tender and chicken fully cooked.
Garnish with parsley and more Parmesan, before serving.
