Tips for rendering tallow

Rendering tallow is a super simple process that I love to share with people. I have been doing it now for a few years, here are some tips that I have picked up along the way.

  • Ask the butcher to grind the fat for you. Then all you have to do is dump it into the crock pot!
  • If you do have to cut or grind the fat, do it when the fat is nice and cold. This makes the cutting much easier and grinding works better.
  • Keep an eye on the tallow as it renders. Turn off the heat as soon as it stops crackling.
  • Strain the tallow while it is still warm enough to flow easily, but not so hot that it might crack a glass jar.

What you need to render tallow

  • 100% grass fed raw beef fat
  • Crockpot (see notes on how to use the stovetop or oven below)
  • Cheesecloth or cotton muslin
  • Metal strainer
  • Ladel
  • Jars to store the finished tallow

The rendering process

Let’s get started!

Source beef fat

To begin, source some high quality beef fat. 100% grass fed is the most ideal, because the nutrient content is the highest. A local Weston A. Price chapter is a great resource in locating farms that raise grass fed beef.

Prepare the fat

Once you have some fat, you’ll grind or cut it up to make the rendering process easy and fast. If the butcher can grind the fat for you, that’s the easiest. If the fat comes to you in chunks, you’ll have to either cut it up as small as you can, or grind it in a food processor.

Begin rendering

Next, toss all of the fat into a crock pot and set the crockpot to low.  Just leave it for a few hours, and check on it every now and then.

As the fat begins to render, it will pop and crackle. Once the noise dies down, and all you see in the crockpot is lots of liquid tallow and some crispy bits, the tallow is done. If you still hear a bit of noise, keep it rendering. You do want to stop the rendering process as soon as the noise stops, though. If you keep the heat on too long, the tallow can start to burn, and we don’t want that.

How to store tallow

Once the tallow is finished and the crock pot is turned off, let it sit for an hour or so to cool. You want the tallow to still be warm enough to stay liquid, but not so hot that it will crack a glass mason jar.

Once the tallow has cooled a bit, strain it through a mesh strainer and some cotton muslin or cheesecloth. I like to store my tallow in glass mason jars. I prefer glass over plastic so that I don’t have to worry about chemicals from plastic leaching into the tallow.

What is tallow?

Tallow is rendered beef fat. Rendering just means to heat it so that it melts down. It can be used in so many different items in your home. It is one of the many parts of the cow that can be used that has been forgotten throughout time, which is a shame. 

If you ask me, every kitchen needs a jar full of tallow – including yours. I am obsessed with tallow and I am convinced that you will be too once you try it!

What is tallow good for?

Grass fed beef tallow is amazing stuff… It’s one of my favorite things ever, because it is so versatile and so full of vital nutrients.

It’s a homesteading essential!

I use tallow to make our skincare products.

Don’t forget about everything that you can use tallow for in the kitchen! For cooking, you can:

  • Fry potatoes in it
  • Create the best homemade French fries ever
  • Use it anywhere you’d use a fat in cooking, to sauté or brown
  • Make the most gorgeous pie crusts ever, using a combo of tallow and butter
  • Melt it and use it in baking

Any way you use it, you can’t beat the high smoke point and amazing array of nutrients in grass fed tallow.

Where to get beef fat for rendering into tallow

When making your own tallow, I recommend finding a local source to purchase grass fed beef fat. A local Weston A. Price chapter is a great resource in locating farms that raise grass fed beef. 

You can also visit your local farmers market or butcher and ask them. Since most farmers know each other, chances are good that someone will be able to point you into the right direction!

How to render tallow on the stove

If you don’t have a crockpot, you can do the same method described above for rendering tallow but in a stock pot on the stove. Simply cook with very low heat and keep an eye on it as the tallow melts. Then, strain and store as described here.

How to render tallow in the oven

To render tallow in the oven, place the raw fat in a metal pan and set the oven to 190ºF (88ºC). Check on it now and then. When it is finished rendering, strain and store. 

You can also put the raw fat inside a metal strainer in the oven, and put the metal strainer inside the pan. This way, you can periodically pour off the tallow as it melts into the pan below. This avoids letting the tallow sit in the heat the entire time, which can make it darker in color. 

Dry rendering versus we rendering

There are two schools of thought for rendering tallow and those are either dry rendering or wet rendering. Both work well and will get you that nutritious tallow that you can use for cooking and creating.

Dry rendering

Dry rendering is the method used to render tallow with no water added, the same method I’ve described here. It is simply just the fat being melted.

I like this method for cooking, because the tallow retains lots of flavor that really adds to foods cooked in it. This is also the fastest and easiest method!

Wet rendering

For the tallow that I use for soap making and skincare, I prefer the wet method. This method uses water and salt to gently render the tallow, keeping the heat lower and drawing impurities out of the fat.

Tallow rendered with this method is very light in color and doesn’t have that beefy smell that you’d rather not have in your jar of tallow balm. I show the entire process for how to wet render and purify tallow to make it odorless and white here

Either method works for cooking. Give them both a try and see which you like best! 

What is the ideal temperature for rendering tallow?

Whether you are rendering tallow in your crockpot or a pot on the stove or in the oven, it is important that you keep the tallow at a consistent temperature of 190°F (88°C). 

This temperature will help the tallow render gently, so that it doesn’t burn. 

How long does it take to render tallow?

To properly render tallow can take anywhere from 8 to 24 hours, depending on the size of fat chunks. The smaller the fat pieces the quicker it will render, which is why I recommend using ground fat. 

Generally I have found that my 6 quart crock pot takes around 10 hours to fully render the tallow. 

How long does tallow keep?

Properly rendered tallow will keep for several months at room temperature or longer. For cooking, I like to refrigerate mine. For longer term storage, I freeze my rendered tallow. Tallow will last for many months in the refrigerator and years in the freezer. 

Benefits of beef tallow

It is no secret how much I love beef tallow! There are so many great things about it and so many uses for it.

Some of the benefits that tallow has are: 

    1. Rich is nutrients
    2. Reduces inflammation
    3. Nourishes the skin
    4. Rich in antioxidants
    5. Contains stearic acid, which helps repair damaged cells
    6. Promotes stable blood sugar
