How To Cook Bone Broth In A Crock Pot

ByLily

Making bone broth in a crock pot allows you to extract deep nutrients over many hours without constant attention. If you want to know how to cook bone broth in a crock pot, the process is simple: add bones, water, and a splash of acid, then let the slow cooker do the work.

The result is a rich, gelatinous liquid you can sip plain or use as a base for soups and stews. This guide walks you through every step, from picking bones to skimming fat.

Why Use A Crock Pot For Bone Broth

A slow cooker holds a steady, low temperature for hours. That is exactly what you need to pull collagen and minerals out of bones.

You do not have to watch a simmering pot on the stove. You can leave the house, go to work, or sleep while the broth cooks.

  • No risk of boiling dry on a hot stove
  • Uses less energy then a full oven
  • Set it in the morning and strain at night
  • Works with beef, chicken, pork, or fish bones

How To Cook Bone Broth In A Crock Pot

Follow these steps for a consistent batch every time. The total active time is about 20 minutes. The rest is waiting.

Step 1: Gather Your Bones

You need about 2 to 3 pounds of bones for a 6-quart crock pot. A mix of joint bones and marrow bones works best.

Chicken feet, necks, and backs give lots of gelatin. Beef knuckles and oxtail add body. Ask a butcher if you do not see them in the meat case.

Roasted bones taste deeper. You can roast them at 400°F for 30 minutes first, but raw bones work fine too.

Step 2: Add Acid And Aromatics

Acid helps draw minerals from the bones. Use 2 tablespoons of apple cider vinegar or lemon juice.

Then add flavor. These are optional but make the broth taste better:

  • 1 onion, quartered (skin on is fine)
  • 2 carrots, chopped rough
  • 2 celery stalks, chopped rough
  • 3 garlic cloves, smashed
  • 1 bay leaf
  • 1 teaspoon black peppercorns

Skip salt for now. You can salt the broth when you use it later.

Step 3: Fill With Water

Pour cold water over the bones until it sits about 1 inch below the rim. Do not overfill, or it will spill as it heats.

Cold water is important. It helps keep the broth clear instead of cloudy.

Step 4: Set The Temperature And Time

Set your crock pot to low. Cook for 12 to 24 hours for beef bones. Chicken bones need only 8 to 12 hours.

Longer is not always better. After 24 hours, the broth can turn bitter or mushy.

If your crock pot runs hot, check it after a few hours. The liquid should barely bubble, not roll.

Step 5: Skim And Top Off

Check the pot every few hours if you are home. Use a spoon to skim off foam and fat from the top.

Add hot water if the level drops below the bones. Cold water can crack a hot ceramic insert.

Step 6: Strain The Broth

Turn off the crock pot. Let it cool for 20 to 30 minutes.

Set a fine mesh strainer over a large bowl or pot. Ladle the broth through the strainer.

Do not pour the whole pot at once. The bones and veggies will clog the strainer.

Press on the solids with a spoon to get the last drops, but do not force it. Pressing too hard makes the broth cloudy.

Step 7: Cool And Store

Let the strained broth cool on the counter for an hour. Then move it to the fridge overnight.

In the morning, a layer of fat will sit on top. You can scoop it off and save it for cooking, or leave it in for extra richness.

The broth should look like jelly when cold. That means you got good gelatin. It will melt when heated.

  • Fridge: up to 5 days in a sealed jar
  • Freezer: up to 6 months in freezer-safe containers
  • Leave 1 inch of headspace if freezing, or the jar may crack

Common Mistakes To Avoid

Most bad batches come from a few small errors. Watch out for these.

Using Too Little Bone

Weak broth means you did not use enough bones. Two pounds is the minimum for a 6-quart pot. Three pounds is better.

Skipping The Acid

Without vinegar or lemon, you get less mineral content. It only takes two tablespoons, so do not skip it.

Letting It Boil

A hard boil makes the broth cloudy and greasy. Keep it at a bare simmer on the low setting.

Not Skimming

Foam and fat left on top can make the final broth taste muddy. Skim every few hours when you can.

How To Use Your Bone Broth

You now have a versatile kitchen staple. Here are easy ways to use it.

  • Sip it warm from a mug with a pinch of salt
  • Use it as the liquid for rice, quinoa, or risotto
  • Swap it for water in soups, stews, and chili
  • Cook noodles or pasta in it for extra flavor
  • Add a splash to sauteed vegetables or mashed potatoes

Final Tips For A Better Batch

Save bones in a freezer bag as you cook. When the bag is full, you are ready to make broth.

Use a mix of bone types. Joints give gelatin, marrow gives richness, and meaty bones give flavor.

Taste the broth before you store it. If it seems flat, simmer it uncovered on the stove to reduce and concentrate the flavor.

Clean your crock pot insert well after each batch. Bone broth leaves a film that can affect the taste of your next meal.

With a little planning, you can keep a steady supply of homemade broth on hand. Your crock pot does the hard part while you go about your day.
