Making bone broth in a crock pot means letting collagen-rich bones simmer low and slow for at least 24 hours. If you’ve been wondering how to cook bone broth in a crock pot, you are in the right place. This method is hands-off, forgiving, and delivers a deeply nourishing broth that beats anything from a store shelf.
You don’t need fancy equipment or a culinary degree. Just a slow cooker, some bones, and a bit of patience. The crock pot does all the heavy lifting while you go about your day. Let’s walk through every step so you can make a rich, gelatinous broth at home.
Why Use A Crock Pot For Bone Broth
A crock pot is ideal for bone broth because it maintains a steady, low temperature. This gentle heat extracts collagen, gelatin, and minerals from bones without boiling them hard. Boiling can make broth cloudy and bitter. The slow cooker keeps things clean and clear.
You also don’t have to watch the pot. No stirring, no adjusting flames. Set it and forget it. This makes it perfect for busy people who want real food without constant attention.
Benefits Of Slow Cooker Bone Broth
- Hands-off cooking for 24 to 48 hours
- Uses less energy than a stovetop simmer
- Reduces kitchen heat in summer months
- Produces a clean, flavorful broth every time
How To Cook Bone Broth In A Crock Pot
This is the core section you came for. Follow these steps exactly and you will have a beautiful broth. The key is prep work and patience.
Step 1: Choose Your Bones
Not all bones are equal. For a rich broth, use a mix of marrow bones, knuckle bones, and meaty bones like oxtail or short ribs. Chicken feet add extra gelatin. Beef bones give a deep, savory flavor.
Ask your butcher for “soup bones.” They often have bags of mixed bones for cheap. Grass-fed or pasture-raised bones yield better nutrition and taste.
Step 2: Roast The Bones (Optional But Recommended)
Roasting deepens the flavor. Place bones on a baking sheet and roast at 400°F for 30 minutes. Turn them halfway. They should be browned, not burnt. This step adds a rich, caramelized note to your broth.
If you are short on time, you can skip roasting. The broth will still be good, just less complex.
Step 3: Add Bones To The Crock Pot
Place the roasted or raw bones in your slow cooker. Fill it about halfway with bones. Don’t overcrowd. You need room for water and vegetables.
For a 6-quart crock pot, use about 3 to 4 pounds of bones. Adjust for smaller or larger cookers.
Step 4: Add Vegetables And Seasonings
Rough chop one onion, two carrots, and two celery stalks. Add them to the pot. Toss in a few garlic cloves, a bay leaf, and a tablespoon of peppercorns. Do not add salt yet. Salt can make the broth bitter during long cooking.
You can also add a splash of apple cider vinegar. The acid helps leach minerals from the bones. About 2 tablespoons for a full pot.
Step 5: Cover With Water
Pour cold, filtered water over the bones and vegetables. Fill to about an inch below the rim. Do not overfill. The broth needs room to bubble slightly without spilling.
Make sure all bones are submerged. If any stick out, they can spoil or dry out. Add more water if needed.
Step 6: Set The Crock Pot To Low
Set your slow cooker to low. Never use high for bone broth. High heat can break down collagen too fast and make the broth cloudy. Low and slow is the rule.
Put the lid on. Let it cook for at least 24 hours. Some people go 48 hours for beef broth. Chicken broth is done in 24 hours.
Step 7: Skim And Strain
After 12 hours, check the broth. You may see foam or impurities floating on top. Skim these off with a spoon. This keeps the broth clear.
When the time is up, turn off the slow cooker. Let it cool for 30 minutes. Place a fine-mesh strainer over a large bowl or pot. Pour the broth through. Discard the solids.
Step 8: Cool And Store
Let the broth cool to room temperature. Then refrigerate it. After a few hours, a layer of fat will solidify on top. You can remove this fat or leave it for flavor. The broth should be jiggly like Jell-O. That means it’s full of gelatin.
Store broth in airtight containers. It keeps in the fridge for 5 days. Freeze for up to 6 months in freezer-safe jars or bags.
Tips For The Best Bone Broth
Small details make a big difference. Here are some pro tips to elevate your broth without extra work.
Use A Mix Of Bones
Combining different bones gives a balanced broth. Marrow bones add richness. Knuckle bones add gelatin. Meat bones add flavor. Chicken feet are cheap and packed with collagen.
If you only use one type, the broth may be thin or one-dimensional. Variety is key.
Don’t Skip The Vinegar
Apple cider vinegar is not for taste. It helps pull calcium and magnesium from the bones. Without it, you get less mineral content. Use about 1 tablespoon per quart of water.
You won’t taste the vinegar after cooking. It evaporates and breaks down.
Keep The Lid On
Resist the urge to lift the lid. Every time you open it, heat escapes. This adds cooking time and can disrupt the simmer. Trust the process.
If you need to check water levels, do it quickly. Add hot water if needed to keep bones submerged.
Season After Cooking
Salt and herbs can become bitter after 24 hours of cooking. Add salt, pepper, and fresh herbs only when you reheat the broth for drinking or cooking. This keeps the flavor bright.
You can also add a pinch of salt to the finished broth before storing. Just go light.
Common Mistakes To Avoid
Even experienced cooks make errors. Here are the most common ones and how to avoid them.
Using Too Much Water
More water does not mean more broth. It means weaker broth. Stick to the recommended amount. You want the bones and vegetables to be submerged, not swimming.
If you add too much water, the broth will be thin and lack flavor. You can always reduce it later by simmering uncovered.
Not Cooking Long Enough
Bone broth needs time. 12 hours is not enough for beef bones. Chicken can be done in 12, but 24 is better. Beef needs 24 to 48 hours. The longer it cooks, the more nutrients and flavor extract.
If your broth does not gel in the fridge, it likely needed more time.
Boiling The Broth
High heat ruins bone broth. It makes it cloudy, bitter, and less nutritious. Always use the low setting on your crock pot. If your slow cooker runs hot, crack the lid slightly to lower the temperature.
A gentle simmer with tiny bubbles is perfect. No rolling boil.
Skipping The Skim
Impurities rise to the top during the first few hours. If you don’t skim them, they sink back in and make the broth cloudy. Skim once or twice for a clear, clean broth.
It takes just a minute and makes a visual difference.
How To Use Bone Broth
Bone broth is not just for sipping. Use it in many recipes to add flavor and nutrition.
- Drink it warm with a pinch of salt as a daily tonic
- Use it as a base for soups, stews, and chili
- Cook rice, quinoa, or lentils in broth instead of water
- Add to sauces and gravies for depth
- Use it to braise vegetables or meats
You can also freeze broth in ice cube trays for small portions. Pop a cube into a pan when sautéing vegetables for instant flavor.
Frequently Asked Questions
Can I Use Frozen Bones For Crock Pot Bone Broth?
Yes, you can use frozen bones. No need to thaw first. Just add them directly to the crock pot. The cooking time may need an extra hour or two to account for the frozen state.
How Long Does Bone Broth Last In The Fridge?
Properly stored in an airtight container, bone broth lasts 5 to 7 days in the refrigerator. Always check for off smells or mold before using. If it smells sour, discard it.
Can I Cook Bone Broth On High In A Crock Pot?
It is not recommended. High heat can make the broth cloudy and less flavorful. It also risks burning the bones. Always use the low setting for best results.
Why Is My Bone Broth Not Gelling?
Lack of gelatin means not enough collagen-rich bones. Add more knuckles, feet, or joints next time. Also, ensure you cook it long enough. Beef needs at least 24 hours. If it still doesn’t gel, you may have used too much water.
Do I Need To Add Salt To Bone Broth While Cooking?
No, do not add salt during cooking. It can become bitter and also draw out impurities. Season only after straining or when reheating. This gives you control over the final flavor.
