Learning how to make chicken stock from a roast chicken carcass turns the part of dinner most people throw away into the best ingredient in your kitchen. One carcass, a pot of cold water, and a few vegetables simmer into a rich, golden stock that beats anything from a carton, and the whole job is mostly hands-off. This guide covers the carcass method step by step, the stock-vs-broth rule, the slow-cooker branch, and the storage system that keeps your stock safe for months.

The carcass is the starting point, so it helps to have a good one. If you roasted the bird yourself, you already have everything you need — and if you want the full roast first, our guide on how to cook a turkey walks through the bird that leaves the best carcass behind. A rotisserie chicken from the store works just as well, and it is the most common starting point for most home cooks.

What Is the Difference Between Chicken Stock and Broth?

Chicken stock is made by simmering bones with vegetables and herbs, while chicken broth is made by simmering mostly meat. That is the whole rule, and it decides everything about how each one tastes and behaves.

Stock gets its body from the bones. Collagen in the bones and joints dissolves into gelatin during a long, gentle simmer, which is why a good stock feels slightly sticky on your lips and sets like jelly in the fridge. Broth, made from meat, is lighter and thinner, and it tastes more like chicken soup because the flavor comes from the meat itself. Earth Food and Fire puts it plainly: stock is made from the raw or roasted bones, broth from simmering mostly meat.

Use stock when the liquid is an ingredient — a soup, a sauce, a gravy — because its gelatin gives the dish body. Use broth when the liquid is the meal itself. And do not worry about the names on the shelf: cartons labeled "stock" and "broth" are used interchangeably by brands, so the rule above is about what you make at home, not what the label says.

What Do You Need to Make Chicken Stock?

You need one chicken carcass, a large pot, cold water, and the classic vegetables. Nothing in the list is expensive, and most of it is already in your kitchen.

• 1 chicken carcass — from a roast chicken or a rotisserie chicken, meat picked off and saved for another meal. If you have no carcass, use the bones from 2 to 3 large chicken breasts, 5 to 6 thighs, 10 wings, or 7 to 8 legs (A Mind "Full" Mom).
• 16 cups of cold water — enough to cover the bones by at least 2 inches (A Mind "Full" Mom; Penn State Extension).
• 1 large carrot, 2 large onions, and 2 stalks of celery — quartered, skins and all. This is the mirepoix, the French base of 2 parts onion to 1 part celery to 1 part carrot (Earth Food and Fire).
• 1 to 2 sprigs of fresh thyme, 2 dried bay leaves, and 1 tablespoon of whole black peppercorns — whole peppercorns keep the stock clearer than ground pepper (Self Reliance Central, citing Penn State Extension).
• 1 tablespoon of kosher salt — or half that, or none at all. Salt at the end is the safer habit, because the stock reduces as it simmers and salt added early concentrates (see the mistakes section).
• A large stockpot, a fine-mesh strainer, and containers for storage — plus cheesecloth if you want the clearest possible result.

Two things do not belong in the pot. Skip strongly flavored vegetables like broccoli and peppers, and never use moldy or rotten produce — both will sour the flavor (Self Reliance Central, citing Penn State Extension). Vegetable scraps are fine: onion skins, carrot peels, and celery tops all work, and a freezer bag of scraps collected over a few weeks is the cheapest way to start.

How to Make Chicken Stock From a Roast Chicken Carcass

Homemade chicken stock from scratch follows six steps: pick the meat off the carcass, cover the bones with cold water, add the vegetables and herbs, bring it to a gentle simmer, skim and simmer for 3 to 4 hours, then strain and cool it fast.

1. Strip the carcass. Pull all the meat off the bones and save it for another meal — soup, chicken salad, sandwiches. Put the bones, skin, and pan juices in the pot. Do not keep raw or cooked bones in the fridge for more than two days before using them; if you will not make stock right away, freeze them (New Mexico State University Extension, via Self Reliance Central).
2. Add the vegetables and herbs. Add the quartered carrot, onions, and celery, the thyme, bay leaves, and whole peppercorns. If you are roasting the bones first (see the next section), do this while they roast.
3. Cover with cold water. Pour in 16 cups of cold water, enough to cover the bones by at least 2 inches. Always start with cold water: it draws impurities out of the bones slowly, and those impurities rise as foam you can skim off (Earth Food and Fire).
4. Bring it up slowly, then simmer — never boil. Heat the pot over medium heat until it just begins to bubble, then turn it down to the lowest heat that keeps a gentle simmer. A rolling boil emulsifies fat and protein into the liquid and makes cloudy, greasy stock. You want the surface barely trembling, with a bubble breaking now and then.
5. Skim and simmer for 3 to 4 hours. In the first half hour, skim off the gray foam that rises to the surface with a ladle or slotted spoon. Then leave the pot alone — do not stir it. Taste at the 3-hour mark: the stock should taste rich and chicken-y, not watery. If it still tastes thin, give it another hour.
6. Strain, cool, and skim the fat. Ladle the stock out through a fine-mesh strainer lined with cheesecloth into a clean bowl or pot — ladling instead of pouring keeps the sediment at the bottom undisturbed and the stock clear. Let it cool to room temperature, then refrigerate it overnight. The fat hardens into a layer on top; lift it off with a clean spoon and your stock is ready to use or store.

One carcass with 16 cups of water yields roughly 10 to 12 cups of finished stock after simmering and straining — the pot loses water to evaporation and the bones and vegetables hold some back. If you start with 10 cups of water instead, expect about 5 to 6 cups of stock (The Mediterranean Dish). The ratio is forgiving; what matters is that the bones stay covered by an inch or two of water for the whole simmer, adding a little hot water if the level drops.

Should You Roast the Bones First?

Roasting the bones first is optional, but it is the one choice that changes the flavor most. Roast them and you get brown stock; skip it and you get white stock — and both are correct, for different dishes.

For brown stock, spread the bones on a roasting pan and roast at 375°F until they are dark golden brown (Earth Food and Fire). The browning adds a deeper, roastier flavor that suits dark sauces, beef-and-chicken stews, and gravy. For white stock, skip the oven and start the raw bones in cold water — the result is paler, cleaner-tasting, and better for light soups, risotto, and anything where you want the stock to disappear into the dish. If you skip roasting, blanching the raw bones in cold water first and draining it helps draw out impurities for a clearer result.

One practical note: roast the vegetables with the bones and you risk a bitter stock — Earth Food and Fire prefers to sauté the mirepoix in the stockpot itself while the bones roast. Either way, do not skip the roast-or-not decision by accident: a carcass straight from the roasting pan is already roasted, so a roast-chicken carcass always makes brown stock unless you deliberately start from raw bones.

How Long Should Chicken Stock Simmer?

Simmer chicken stock for 3 to 4 hours on the stove for a full-flavored stock, or 8 to 12 hours on low in a slow cooker. Shorter simmers still work, but they give you a lighter stock.

The long simmer is where the gelatin comes from. Collagen in the bones and joints needs hours to dissolve, and that is what gives stock its body — taste at the 4-hour mark and the stock should almost coat your mouth with a rich, sticky feeling. When it cools completely, do not be surprised if it sets almost like jelly: that is the sign of a good, strong stock (Earth Food and Fire). A single small carcass will not set as firmly as two or three carcasses, because there is simply less collagen to go around — so never promise a jelly-set stock from one small carcass without enough bones.

Time is flexible in one direction only. Simmering longer than planned just concentrates the stock — add a little water if the level drops below the bones. Simmering less than 2 hours gives you a light stock that still works for soup, but it will not have the body for sauces or gravy.

How to Make Chicken Stock in a Slow Cooker

Chicken stock in a slow cooker follows the same method with one change: combine everything in the crockpot and cook on low for 8 to 12 hours, then strain and cool (A Mind "Full" Mom). It is the best branch for anyone who does not want to watch a pot.

Put the carcass, vegetables, herbs, and cold water in the slow cooker, set it to low, and walk away. There is no skimming schedule to keep — the gentle, even heat keeps the simmer low on its own, and the lid keeps the water level steady. After 8 to 12 hours, strain through a fine-mesh strainer, cool to room temperature, and refrigerate overnight before skimming the fat. The only trade-off is time: the slow cooker is slower than the stove by design, so start it in the morning or before bed.

The slow-cooker branch is also the safest way to make stock from a rotisserie chicken carcass on a weeknight. Put the carcass in the pot after dinner, set the cooker to low, and wake up to finished stock — the most common starting point, and the easiest one.

How to Store Chicken Stock (and How Long It Lasts)

Cool chicken stock fast, then refrigerate it for 3 to 5 days or freeze it for 3 to 6 months. The exact numbers differ between sources because they measure different things — the range below gives you the safe version of each.

Cool it fast. This is the step people get wrong. A big pot of hot stock cools slowly, and that leaves it in the temperature range where bacteria grow. Penn State Extension says to get stock to room temperature within two hours: split it into several small containers, or set the pot in a sink of ice water and stir often, then move it to the refrigerator to finish chilling (Self Reliance Central).

Fridge rules. Penn State Extension puts the fridge life at about 3 days at 40°F or below, while A Mind "Full" Mom gives 5 days. Both agree on the practice: refrigerate overnight, skim the solidified fat off the top, and use the oldest container first. Label every container with the date.

Freezer rules. Freeze in freezer-safe containers or wide-mouth jars, leaving about 1 inch of room for the stock to expand. A Mind "Full" Mom gives 3 months in the freezer; the University of California's Master Food Preserver Program gives 6 months. The ice-cube-tray trick is the most useful version: freeze the stock in trays, pop the cubes into freezer bags, and thaw exactly what a recipe needs — about 5 to 6 cubes equals 1 cup (Food.com).

Thawing. Thaw in the refrigerator or right in the cooking pot — never on the counter (Self Reliance Central, citing Penn State Extension). And if you want shelf-stable jars, stock is a low-acid food, so it must be pressure canned, never water-bath canned: Penn State's tested directions process pints for 20 minutes and quarts for 25 minutes at 11 pounds on a dial gauge or 10 pounds on a weighted gauge, at elevations up to 1,000 feet.

What Can You Use Homemade Chicken Stock For?

Homemade chicken stock is the base for soup, the liquid for risotto and rice, the body of a pan sauce, and the secret ingredient in gravy. Once you have a freezer full of it, you will reach for it constantly.

The most direct use is the gravy on the same holiday table the carcass came from — our guide on how to make gravy starts with stock for exactly this reason, and the stock you make today is the gravy you serve at the next roast. It is also the base for any soup you make from the leftover meat: reheat the turkey, add stock, and you have a second dinner instead of a plate of dry slices, as our guide on how to reheat turkey explains.

For everyday cooking, swap stock for water wherever the liquid matters: cooking rice or grains, deglazing a pan after searing meat, braising vegetables, or thinning a sauce. The ice-cube portions are made for this — drop two or three cubes into a pan sauce and you get instant depth without opening a carton. And on the Thanksgiving table, stock ties the whole meal together: the turkey, the gravy, and how to make cranberry sauce all sit on the same plate, and the stock pot is what turns the leftovers into the next three meals.

Mistakes That Ruin Chicken Stock

Most bad stock comes from one of five mistakes, and all five are easy to avoid once you know them.

• Boiling it hard. A rolling boil emulsifies fat and protein into the liquid and makes cloudy, greasy stock. Keep the pot at a bare simmer — the surface should barely tremble (Earth Food and Fire; The Mediterranean Dish).
• Salting at the start. Salt concentrates as the stock reduces, so a pot salted early can turn inedibly salty by hour four. Salt at the end, after you taste the finished stock — or leave it out entirely and salt the dish you cook with it (A Mind "Full" Mom).
• Stirring the pot. Stirring breaks up the solids and clouds the stock. Leave it alone, skim the foam off the top, and ladle the finished stock out instead of pouring it (Earth Food and Fire).
• Cooling it slowly. A big pot left on the counter stays warm for hours, in the range where bacteria grow. Split it into small containers or use an ice bath, and get it to room temperature within two hours (Penn State Extension).
• Using the wrong vegetables. Broccoli, peppers, and anything moldy or rotten will sour the flavor. Stick to onion, carrot, celery, and mild herbs (Penn State Extension).

Frequently Asked Questions

Can I make chicken stock from a rotisserie chicken carcass?

Yes — a rotisserie chicken carcass is the best starting point for most home cooks. Pick the meat off, put the bones and skin in the pot with the vegetables and cold water, and follow the same method. The carcass is already roasted, so you are making brown stock, which has a deeper flavor.

How long does homemade chicken stock last in the fridge?

Homemade chicken stock lasts 3 to 5 days in the refrigerator at 40°F or below. Penn State Extension gives about 3 days, while A Mind "Full" Mom gives 5 days — use the shorter number if the stock sat out at all, label the container with the date, and use the oldest first.

Can I freeze chicken stock?

Yes. Freeze chicken stock for 3 to 6 months in freezer-safe containers or jars, leaving about 1 inch of headroom for expansion. The ice-cube-tray method is the most practical: freeze the stock in trays, bag the cubes, and thaw only what you need — about 5 to 6 cubes equals 1 cup.

What is the difference between chicken stock and chicken broth?

Chicken stock is made by simmering bones with vegetables and herbs, while chicken broth is made by simmering mostly meat. Stock has more body because collagen from the bones turns into gelatin, so it sets like jelly in the fridge. Broth is lighter and thinner, and it tastes more like chicken soup.

Why is my chicken stock cloudy?

Cloudy stock almost always comes from boiling too hard or stirring the pot. A rolling boil emulsifies fat and protein into the liquid, and stirring breaks up the solids. Keep the pot at a bare simmer, never stir, skim the foam in the first half hour, and ladle the finished stock out through a cheesecloth-lined strainer instead of pouring it.
