Preheat Oven to 350°F.
Wash chicken inside and outside and pat dry with paper towels.
Cut onions into quarters and then cut again into eighths. Place the onion chunks in the bottom of the Dutch oven.
Place the whole chicken, breast side up, on top of the onions and sprinkle liberally with salt.
Add enough water to the Dutch oven to cover the bottom of the chicken and onions. Don’t cover the entire chicken; just a couple of inches from the bottom will do.
Place one sprig of fresh thyme into the water for flavor.
Cover the chicken with the lid if you have one, and place it in a preheated oven for 30 minutes.
Turn the oven temperature down to 275°F and cook for another 60 minutes.
Remove the lid and cook for another 30 minutes so the chicken browns up beautifully.
Remove the chicken from the oven and place it on a platter. Homesteading Hack: Allowing the chicken to rest on a large platter for at least ten minutes ensures that the juices absorb back into the chicken, keeping it nice and moist.
With a slotted spoon, remove the cooked onions from the Dutch oven and place them around the chicken.
