There are two basic ways to make chicken stock. One method uses the leftover bones from a chicken carcass and vegetables, and takes several hours of slow cooking. The second method uses chicken backs and wings, braising them first, and takes about 1 hour to prepare. We prefer this second method as it yields a more rich, delicious stock. But the first method can be a great way to not let good bones go to waste.

Method 1. Leftover Chicken Bones

1 Put the leftover bones and skin from a chicken carcass into a large stock pot and cover with cold water. Add veggies like celery, onion, carrots, parsley.

2 Add salt and pepper, about 1/2 tsp of salt, 1/4 tsp of pepper.

3 Bring to a boil and reduce heat to bring the stock to a low simmer.

4 Simmer uncovered at least 4 hours, occassionally skimming off the foam that comes to the surface.

5 Remove the bones and strain the stock.

6 If making stock for future use in soup you may want to reduce the stock by simmering a few hours longer to make it more concentrated and easier to store.

Method 2. Chicken backs, wings, and legs.

4 lbs of chicken backs, wings, and or legs that have been hacked with a cleaver into 2-inch pieces. You can ask your butcher to prepare the chicken pieces this way.
1 large yellow onion, chopped.
Olive oil
2 quarts of boiling water
2 teaspoons of salt
2 bay leaves

1 Heat 1 Tbsp of olive oil in a large stock pot. Add one chopped onion. Sauté until softened and slightly colored - 2 to 3 minutes. Transfer to a large bowl.

2 Add half of the chicken pieces to the pot. Sauté until no longer pink, about 4 to 5 minutes. Transfer cooked chicken to bowl with onions. Sauté the rest of the chicken the same way. Return onion and chicken pieces to the pot. Reduce heat to low, cover, and cook until chicken releases its juices, about 20 minutes.

3 While the chicken pieces are cooking, fill a large tea kettle with 2 quarts of water, bring to a boil.

4 After the chicken pieces have been cooking for 20 minutes, raise the heat level to high, add the 2 quarts of boiling water, 2 teaspoons of salt, 2 bay leaves. Return to simmer, then cover and barely simmer for about 20 minutes.

5 Strain broth and discard solids. Broth can be covered and refrigerated for up to 2 days or frozen for several months.

This method comes from The Best Recipe cookbook by Cook's Illustrated. They got it from In Pursuit of Flavor, by Edna Lewis. This makes a truly flavorful stock.

Note about the Fat
I've seen a lot of newer cookbooks advocate the skimming of the fat from the stock. We prefer the traditional method of letting the fat settle in a layer on top of the stock as it cools. This way, the fat acts as a protective layer against bacteria, which is found in the air. The stock will last longer if you keep the fat layer on it. Just lift up the layer of fat and remove the stock when you want to use it. Every few days, bring the stock to a simmer for 10 minutes and let it cool, again with the fat forming a protective layer. Your stock can be stored in the refrigerator and used for up to a couple of weeks this way.
