Tender, fall-off-the-bone chicken! Skip the overnight refrigeration if you are in a hurry. For variety, eliminate the onion and substitute a quartered lemon or two, stuffed into the chicken cavity.

4 teaspoons salt
2 teaspoons paprika
1 teaspoon cayenne pepper
1 teaspoon onion powder
1 teaspoon thyme
1 teaspoon white pepper
½ teaspoon garlic powder
½ teaspoon black pepper
1 large roasting chicken
1 cup chopped onion

Preparation

In a small bowl, combine the spices.

Remove any giblets from chicken and clean chicken.

Rub spice mixture onto the chicken.

Place in resealable plastic bag and refrigerate overnight. (I usually skip this step because I am always in a hurry).

When ready to cook, put chopped onion in bottom of crock pot.

Add chicken. No liquid is needed, the chicken will make it's own juices.

Cook on low 4-8 hours.

Note: I highly recommend a pop-up timer in the chicken because some crock pots cook faster/slower than others (my crock pot cooks this recipe in 4-5 hours).
