This delicious and homey one-dish meal for crock pot chicken wild rice casserole is very rich and easy. We love how the wild rice cooks in the crockpot, absorbing the flavors of the other ingredients. You can substitute chicken thighs for the chicken breasts in this easy recipe. The cooking time will be longer; add about 2 hours. And always make sure that chicken is cooked to 165 f as measured with a reliable thermometer. Serve this wonderful recipe with a tossed green salad mixed with sliced mushrooms, avocados, and tiny grape tomatoes. The perfect finishing touch for the salad is a creamy italian salad dressing.
