Ever stood in the grocery aisle staring at boxes of chicken stock and bone broth wondering what exactly makes them different? I know I have! These two savory liquids seem similar but have key differences that can impact your cooking. Let’s dive into the tasty world of these kitchen staples and clear up the confusion once and for all.
The Quick Answer
The main difference between chicken stock and bone broth is cooking time and purpose:
- Chicken stock: Simmered for 4-6 hours using primarily chicken bones and vegetables
- Bone broth: Simmered for 12-48 hours using bones and connective tissues, resulting in higher collagen content
Understanding Stock: The Cooking Foundation
Stock is a fundamental ingredient in professional kitchens. As noted by culinary experts, “Stock is a cooking liquid in which animal bones and connective tissue are cooked for a long period, yielding a thick, collagen-rich liquid.”
What Makes a Chicken Stock?
Chicken stock typically includes:
- Chicken bones (backs, necks, wings)
- Mirepoix (onions, carrots, celery)
- Herbs and spices
- Water
- Cooking time: 4-6 hours
The shorter cooking time (compared to bone broth) still extracts good flavor but doesn’t fully break down all the collagen from the bones. The result is a light to medium-bodied cooking liquid that forms the base of many dishes.
A chef at The Chopping Block notes that stock is used “about as frequently as we might refer to salt and pepper. It is the backbone of cooking.” Most culinary professionals consider stock an ingredient rather than something you’d drink on its own.
Bone Broth: The Nutrient Powerhouse
Bone broth has become incredibly popular in recent years, especially among health enthusiasts. Some chefs actually argue that “bone broth” is just a trendy marketing term for what’s essentially a very long-cooked stock.
What Makes a Bone Broth?
Bone broth typically includes
- Animal bones (can be chicken, beef, pork, etc.)
- Connective tissue
- Vegetables
- Herbs and spices
- Water
- Cooking time: 12-48 hours (much longer than stock!)
The extended simmering time is crucial – it allows for maximum extraction of minerals, collagen, gelatin, and other beneficial compounds from the bones This results in a rich, thick liquid that turns gelatinous when cooled (that’s the collagen!).
Key Differences Breakdown
| Feature | Chicken Stock | Bone Broth |
|---|---|---|
| Cooking Time | 4-6 hours | 12-48 hours |
| Primary Ingredients | Chicken bones + vegetables | Bones + connective tissue |
| Consistency | Lighter | Thicker, more gelatinous when cooled |
| Flavor | Mild to medium | Rich, intense |
| Primary Use | Cooking base | Can be sipped alone or used in cooking |
| Nutritional Profile | Good | More collagen, minerals, amino acids |
The Collagen Factor
One of the biggest differences is the collagen content. The extended cooking of bone broth breaks down more collagen from bones and connective tissues, transforming it into gelatin.
Want to test if your broth has plenty of collagen? Let it cool in the refrigerator. If it looks like “meat Jell-O,” congratulations! You’ve got a collagen-rich bone broth. This doesn’t typically happen with regular chicken stock.
Health Benefits: Is Bone Broth Actually Superior?
Many health claims surround bone broth, but what’s actually backed by science?
Potential Benefits of Bone Broth:
- Gut health support: The gelatin may help protect the intestinal lining
- Joint protection: The collagen could support joint health
- Immune function: Amino acids like glutamine may support immune health
- Protein source: Contains essential amino acids
It’s worth noting that chicken stock still contains valuable nutrients – just not in the same concentration as bone broth. A 2017 study published in the Journal of Renal Nutrition found that chicken soup made with bone broth contains significantly more protein and nutrients than soup made with regular broth.
Can You Use Them Interchangeably?
The short answer: sometimes.
The longer answer: It depends on your recipe. For everyday cooking where stock or broth is just one component (like in a risotto or soup base), you can often substitute one for the other without major issues. However, for recipes where the liquid is the star (like a simple broth soup), the richer flavor of bone broth might overwhelm more delicate dishes.
Making Your Own at Home
I’ve tried making both at home, and honestly, the process is similar – it’s mainly the cooking time that differs!
Basic Chicken Stock Recipe:
- Roast chicken bones (optional but adds flavor)
- Place bones in a large pot with chopped onions, carrots, celery
- Cover with cold water
- Bring to a simmer (never boil!)
- Cook for 4-6 hours, skimming occasionally
- Strain and use or store
Basic Bone Broth Recipe:
- Follow steps 1-4 above
- Add a splash of apple cider vinegar (helps extract minerals)
- Simmer for at least 12 hours, up to 48 hours
- Add more water as needed
- Strain and use or store
A Note on Store-Bought Options
Let’s be real – not everyone has time to simmer bones for 24+ hours! When buying packaged products:
- Check the ingredient list: Look for simple, recognizable ingredients
- Consider organic options: Especially important for bone broth as toxins can concentrate in bones
- Compare protein content: Higher protein often indicates more collagen
The article from Organixx warns that consuming bone broth from animals that ate feed sprayed with glyphosate (like Roundup) isn’t ideal for health. As GMO expert Jeffrey M. Smith explains: “If you’re doing bone broth and you’re taking bones from animals that have been fed largely Roundup Ready soy or corn or canola meal or cotton meal or alfalfa… there’s a tremendous amount of Roundup going into the animal. Moving into the bone.”
The Broth Confusion
Adding to the confusion is the term “broth” itself. Chefs often use “broth” to refer to the liquid that occurs during cooking, while home cooks might use it interchangeably with “stock” or “bouillon.”
Traditional broth is made primarily from meat (not bones), cooks for less time than stock, and doesn’t become gelatinous when cooled. So the term “bone broth” is actually a bit contradictory from a culinary perspective!
Which Should You Use?
Here’s when to use each:
Use Chicken Stock For:
- Everyday cooking
- Recipes where the liquid is one component
- Lighter dishes where you don’t want overwhelming flavor
- When cooking time is limited
Use Bone Broth For:
- Sipping on its own
- When you want richer flavor
- When the nutritional benefits are important
- Dishes that benefit from collagen content
FAQs About Chicken Stock and Bone Broth
Can vegetarians consume bone broth or chicken stock?
No, neither is vegetarian-friendly. Look for vegetable stocks instead.
Can I make stock or broth in a pressure cooker?
Yes! Pressure cookers significantly reduce cooking time, though some argue the traditional slow-simmered method extracts more flavor and nutrients.
How long can I store homemade stock or broth?
About 3-4 days in the refrigerator or up to 6 months in the freezer.
Is one better for weight loss than the other?
Bone broth is higher in protein which may help with satiety, but neither is a magic weight loss solution.
Can I use chicken meat instead of bones for stock?
You can, but the result will be more of a traditional broth – lighter in flavor and without the gelatin content that comes from bones.
The Bottom Line
While chicken stock and bone broth share similarities, the extended cooking time and resulting nutrient extraction make bone broth the richer, more collagen-packed option. Stock serves as a versatile cooking base, while bone broth can do double-duty as both an ingredient and a standalone health beverage.
Whether you choose stock or bone broth ultimately depends on your cooking needs, time constraints, and health goals. And remember – homemade versions of either will almost always taste better than store-bought!

Instant Electric Pressure Cooker Chicken Stock
1 rotisserie chicken carcass 1 large onion 2 carrots 2 celery stalks 2-4 cloves garlic 8 sprigs of fresh parsley 6 sprigs of fresh thyme 2 bay leaves 10 whole peppercorns or fresh cracked pepper 1 teaspoon salt (optional) 8 cups water
1. The carrots do not need to be peeled and the onion skin can be left on. Chop scrubbed vegetables into 1-inch chunks. Peel the garlic. 2. Turn the electric pressure cooker on to the low sauté mode. Add the chicken carcass pieces and sauté for 2-3 minutes, or until browned and pieces begin to stick to the bottom of the pot. Press the cancel button to turn off the heat. 3. Add the chopped vegetables, garlic cloves, and herbs to the pot. Pour 8 cups of cool water over the contents of the pot. Do not fill more than 2/3 to the top. 4. Lock the lid into place, close the steam release valve, and press the “manual” button. Adjust the cooking time to say 30 minutes if that is not the default. The display will turn to “ON” indicating that it is heating and pressure is building. 5. After the pot reaches high pressure (this takes about 10-15 minutes), the display will count down 30 minutes. When 30 minutes is up, it will beep and switch to “keep warm” mode. Press the cancel button and allow the pressure in the pot to reduce naturally (this varies but expect at least 15 minutes). 6. Strain the stock using a fine wire mesh strainer and discard all bones, spices, herbs, and vegetable scraps. Taste the stock and add salt if desired. 7. Place the stock in air-tight containers and refrigerate until completely cool. When the stock chills it will likely turn gelatinous because the collagen will be suspended throughout the liquid. If there is a layer on the top that can be skimmed off, you can skim this off if you want.
8. Keep the stock refrigerated and use it within three days, or freeze it for longer storage.

If you don’t have an electric pressure cooker, all is not lost, you can make it on top of the stove. IFAS Extension published a similar recipe in which a leftover turkey carcass was simmered from four to 24 hours to make stock.
It just takes time, but could be worth it when you have control.
