Hail to the chicken carcass! I roast a chicken now and then. We actually prefer to use the meat for salads and sandwiches then make soup rather than eat it roasted with traditional sides. Poultry cooked on the bone has a richer flavor. And since these chickens worked hard to grow tasty, I feel obligated to cook them to their tastiest.
Place chicken carcass in a large (8 qt) stock pot and fill with filtered water 2 inches shy of covering the chicken. Put the lid on and set to simmer for about an hour. You can also do this in your crock pot for 3+ hours.
Once broth has reached a rich color, remove bones, leaving behind chicken bits. Add to your pot:
2 onions, chopped
1 stalk celery, cleaned and chopped (I include the leaves)
1 lb carrots, peeled and sliced
3 TB butter (Since there was no skin, the extra fat makes a world of difference to the flavor)
4 cloves garlic
3 bay leaves
2 TB thyme
1 tsp celery seed
2 1/2 Cups rice
Bring to a boil then simmer for 30 minutes. Or, in a crock pot, let soup cook on low for up to 5 hours.
Add salt and pepper to taste before serving.
