If you want to cook a whole chicken in the Crockpot without liquid, roll some aluminum foil into balls a little bigger than golf ball size, and put about 4 of them in the Crockpot. Rub some oil on the outside of the chicken and sprinkle with seasoned salt or rotisserie chicken seasoning. Then set it on top of the aluminum foil balls, cover, and cook on high for 4-6 hours.
Another easy Crockpot chicken recipe in to cut up the chicken and put it in the Crockpot with a jar of salsa, a can of black beans, and a couple of cups of corn.
One I like is to sprinkle the cut-up chicken with paprika and pepper and put it in the Crockpot. Add a mixture of a large (20 oz) can of crushed pineapple, 2 Tbsp each Dijon mustard and soy sauce, and 2 cloves crushed garlic. Cook on low for 7-9 hours.
