How To Make Bone Broth In Slow Cooker

slow cooker
Written by Kelvin Omere

There are many types of bone broth with hundreds of recipes online that claim to make the best-tasting bone broth.

However, the secret to making the perfect bone broth might not be in the recipe, you choose but the cookware you use. One of the cookware that aids in making the best bone broth is the slow cooker.

Bone broth made with a slow cooker tends to have a better flavor than those made other cookware. The slow cooker or crockpot is basically an electrical cooking appliance used to simmer food at a lower temperature.

Compared to other cooking methods, the slow cooker can operate at lower temperatures for a long period of time.

Other than bringing out the flavor from the broth, the slow cooker would help you save on electricity as it may use less electricity than many other cooking appliances.

It is important to use energy-saving methods to prepare your broth as you would be simmering for about 24 hours.

Slow Cooker Basics

When using the slow cooker, there are several things you need to know or you would end up making several mistakes that would leave you with a low-quality broth.

Let it do its job

The slow cooker takes a considerable amount of time to reach a target temperature, it keeps this temperature going till the broth is done and ready to serve or store.

However, lifting the lid while the cooker is still on will allow most of the hot air escape thus reducing the temperature inside the cooker and increasing the time it would take to perfectly cook the broth while cooking the broth for long periods is great, you wouldn’t want to cook it for too long.

When using the slow cooker, ensure that the lid is closed properly and leave it so until you are ready to serve.

Most bone broth slow cooker recipes wouldn’t require you to open the lid every now and then to check how things are going in the pot so there is no reason for you to alter the temperature inside the cooker.

Use the right size of cooker

To make bone broth, you would normally require a large crockpot, however, some bone broths require larger pots due to the type of bones used.

If you are using a lot of bones, it is expected you will go for a really large pot that will not only contain the bones but also leave space for other ingredients. It is important to get a sizable crockpot when cooking your bone broth.

Many bone broth recipes will ask you to fill the pot with water till the ingredients and the bones are all submerged in water.

Depending on the number of bones you are using, this would mean you will have to add a lot of water to the crockpot. However, there are some downsides to adding too much water to the slow cooker.

If your slow cooker is too full, you could end up with an overflow or your broth will not be cooked properly. For someone who spent more than 24 hours to prepare their broth, this could be heartbreaking.

Also, if your pot is not full enough, the broth would end up being overcooked. Depending on the number of bones, vegetables, spices, and herbs, you want to use to prepare your broth, you should get a slow cooker with a capacity of 6-quart or more.

Ensure all the ingredients fit comfortably into the crockpot with enough room to spare even after filling it with water.


With a cooking time of 24 hours or more, it is easy to overcook your broth. Cooking your broth for long periods would be considered a good thing as the longer cooking time helps to liberate beneficial nutrients in the bone.

But if you are adding vegetables, spices, and herbs to boost the flavor and nutritional value of the broth, you would want to be cautious about the cooking time you allow.

Vegetables also tend to lose vitamins and other trace elements at temperatures below the boiling point which is exactly when the slow cooker works best, however, this can be prevented by keeping the lid on.

Bone Broth In Slow Cooker Recipes

Below, you will find several bone broth recipes for different kinds of bones, these recipes follow the same basic step in making bone broth with the slow cooker, however, we added something more to each recipe.

Since the most popular bone broth choices are chicken and beef bone broth, we made sure they were included in this recipe list.

How to make Beef Bone Broth Using Slow Cooker

Beef broth is made from beef bones, however, not just any beef bone will give you the best broth. There are some beef bone parts that are nutrient-dense and contribute to the flavor of the broth – so when making beef bone broth you should concentrate on these parts alone.

These parts include knuckles, marrow bones, oxtails, and short ribs. If you are unable to get these parts you can settle for the parts you were able to find.

Before cooking the broth, it is recommended that roast the bones to boost the flavor of the broth. Leaving a little meat on the bones would also help boost the flavor. Below you will find the beef bone broth recipe for slow cooker | crockpot.


  • Beef bones
  • Celery
  • Bay leaf
  • Chopped Carrots
  • Chopped Onions
  • Apple cider vinegar (2 tablespoons)

  1. Preheat the oven to 400F and spread the bones on a pan or tray in a single layer. Place it in the oven and allow it to roast for 30 minutes, then flip the bones to the other side and allow it to roast for another 30 minutes.
  2. Place the roasted bones, vegetables, spices, herbs and apple cider vinegar in the crockpot (You can go for either a 6-quart or 10-quart crockpot, however, the number of bones you are using will determine the size of the pot you should use).
  3. Fill the pot with cool water till all the ingredients are submerged by the water. Bring the heat to low and cook for 24 hours. In the first 3 hours of cooking, leave the lid open and skim the foam that forms at the top of the pot.

  6. You can store the broth in the refrigerator for up to 5 days or in the freezer for about 3 months.

How to make Chicken Bone Broth Using Slow Cooker

For this recipe, we decided to add more herbs, spices, and vegetables to boost the flavor and nutritional value. When going for chicken bones, the best parts to settle for include the wings, feet, and backbones.

Another difference between this recipe and the one for beef bone broth is that you’re adding the apple cider vinegar before you start cooking all the ingredients in the crockpot.

This has the same effect (that is, it still makes it easier for the nutrients in the bone to be liberated into the broth), but you will notice a better flavor in the chicken bone broth.


  • Chicken bones
  • Celery
  • Bay leaf
  • Chopped Carrots
  • Chopped Onions
  • Peppercorns (1teaspoon)
  • Parsley (6 sprigs)
  • Thyme (3 sprigs)
  • Oregano (1 teaspoon)
  • Apple cider vinegar (3 tablespoons)


Roast your chicken bones by following the guidelines provided in the beef bone broth recipe.

  1. Place the chicken bones in the crockpot and add your apple cider vinegar. Fill the pot with water till the bones are submerged by the water and let it sit for 30 minutes.
  2. Add all the other ingredients and start cooking. Cooking time should be at about 24 hours.

From this point, you can follow the steps already provided in the beef bone broth recipe as they are similar and will give you the desired result.

Things To Consider When Buying A Slow Cooker

Slow cookers come in a wide range of prices that are determined by the functions, durability and the manufacturer of the slow cooker. Here are some things to consider when buying a slow cooker.


There are many brands claiming that their slow cooker models are better than the other. These brands present different designs that should make using a slow cooker very easy. We’ve found out that only a few of these designs really make things easier.

When going for a slow cooker, check out for the material used in making the cooker. Ceramic, porcelain and metal slow cookers are the popular options, however, metal slow cookers do a better job of conducting heat.

You should also check if the design makes it easy to clean the cooker. If the crock and heating unit of the slow cooker are fused together, you’ll have a hard time maintaining and cleaning the cooker.

Slow cookers that come with knobs and buttons are harder to clean which is why you should go for options that come with touchpad controls


Slow cookers come in many sizes that should suit every household size. You can find 3-quart, 4-quart, 5-quart, 6-quart and even 10-quart slow cookers.

Normally, you’ll have to consider your household size when buying a slow cooker, but in this case, you’ll have to think differently. Since you’re going to make bone broth with this slow cooker, you’ll need something that can fit the bones.

It is best to go for a 6-quart slow cooker which is the recommended size for most household and slow cooker recipes.

If you plan on using the slow cooker for more than making bone broth then you can go for a size of 7 or 8 quarts.

Cooking Feature

There are two types of slow cookers when it comes to cooking features – manual and programmable slow cookers. Programmable slow cookers are the most preferred option, however, they cost a lot more.

With programmable cookers, you can set a cooking time using the digital timer. A keep-warm setting automatically switches on to keep the food warm when the set time is up. Some programmable slow cookers also come with manual mode.

Manual cookers, on the other hand, come with only a few settings, you only get to turn the cooker to low, medium or high. The timer and keep-warm features are absent so you’ll have to monitor the cooking yourself.

The good news is that you can use any of these cookers to cook a nutritious bone broth. However, if you want a little more comfort, you can always go for the programmable slow cooker.

Additional Features

Some slow cookers come with additional features like a sear function that makes sautéing vegetables or browning meats easier. Features like this make the cooker more expensive.

However, you wouldn’t need to consider the sear function if you’re buying the slow cooker just for bone broth. Despite that, we advise you to consider all features because you might end up using the slow cooker for more than making bone broth.


When cooking, you might need to look at the food to monitor the progress. Sometimes, you’ll find yourself lifting the lid to see the food clearly.

Doing this leads to temperature fluctuations and makes harder for the cooker to cook the food properly. This is why you should go for a slow cooker with a glass or clear plastic lid.

Some slow cookers come with lids that lock. This prevents the food from spilling while the cooker is being moved.


The price of a slow cooker can be anything between $10 and $300. The brand, durability, functions, and size of the slow cooker are the major factors that determine the price of the slow cooker.

A high-end model which is quite expensive could last you for many years if you used properly.

Most slow cookers are reasonably priced, so you’re more likely to end up getting the value for your money.
