Start by spraying the inside of your slow cooker with cooking spray. This will prevent the chicken from sticking, making it easier to remove once cooked.
Next, take some kitchen foil and create a ring on the bottom of the slow cooker. This ring will act as a rack for the chicken and allow airflow under it, ensuring even cooking.
Add the chopped onion, bell pepper, and celery to the bottom of the pot. These vegetables not only add flavor but also help to keep the chicken moist during the cooking process.
Create two strips of foil by folding them over and over, letting them hang over the sides. These will serve as handles to easily lift the chicken out once it’s fully cooked.
In a small bowl, mix together the seasonings: garlic powder, onion powder, kosher salt, and poultry seasoning. This combination adds a savory depth of flavor to the chicken.
Take your whole chicken and pat it dry with paper towels. This helps the skin crisp up. Then, rub the seasoning mixture all over the chicken, ensuring it’s evenly coated.
Place the seasoned chicken inside the slow cooker, on top of the foil strips and ring. The foil strips will help lift the chicken out once it’s fully cooked.
Cover the slow cooker with the lid and cook the chicken on HIGH for 4 to 6 hours, or on LOW for 6 to 8 hours. The cooking time will vary depending on the size of the bird and your slow cooker model.
When the chicken is ready, the internal temperature should reach 170 to 175 degrees Fahrenheit. Use a thermometer for accuracy.
Carefully remove the chicken and transfer it to an oven-safe dish. Broil it for about 5 minutes in the oven until the skin is crispy and golden brown. This step adds a delightful crunch to the dish.
Serve the chicken hot with your choice of sides. Enjoy the fruits of your labor!
