What is Beef Tallow?

“Tallow” is a fancy name for rendered fat. Specifically, beef tallow is beef fat that has been cooked down with impurities removed. Tallow is a liquid when heated and a solid when cool, making it a great substitution for oil and butter in recipes.

Tallow used to be used much more often until vegetable shortening and other oils became mainstream, but there is no reason why it can’t be used when cooking at home. It’s also a great way to use up all those trimmings leftover from Trimming a Brisket to get the most bang for your buck when purchasing a whole-packer brisket.

Beef tallow is extremely versatile. In the past, it was often used in making candles, soaps, skin products, and much more. For those of us into BBQ, beef tallow is a great item to have on hand for cooking as it’s packed full of flavor that brings a different element to sautéed veggies and cooked potatoes.

Tools for Making Beef Tallow

Making beef tallow is not difficult, but there are a few items and tools you’ll need to have on hand to help you achieve that gorgeous, smooth beef tallow as a final product. I’ve linked a few of the things you’ll need to assemble prior to rendering the tallow.

  • 16-quart stock pot. The fat cooks down in a stock pot, and I recommend you use a bigger pot that you think you’ll need. You don’t want any fat splashing on your countertops or stove top, believe me.

  • Fine mesh strainer. Make sure you have a pretty fine strainer on hand to strain all the large pieces of meat and other impurities that don’t cook down with the fat.

  • Funnel. A funnel is a must-have when doing the final straining into your storage jar(s). Any funnel will do here. I linked a funnel/strainer combo so you can snag both and have fewer items to purchase for making this tallow.

  • 100% cotton cheesecloth. Cheesecloth is the best item to use to do the final straining, but if you don’t have any on hand, you can also use a coffee filter or paper towel.

  • Wide-mouth mason jars. A wide-mouth mason jar makes the perfect jar for storing your tallow. The wide mouth makes it easier to get the tallow in and out, and it’ll store nicely in the fridge.

How to Render Beef Tallow

Once you have all your tools gathered, you’re ready to render some beef tallow! Do not be intimidated by this process! Once you’ve tried it, you’ll find it’s pretty straightforward.


Gather the beef fat in a large stock pot, and heat to a low simmer. Low and slow temperatures while you render or the fat will result in a browned tallow with a funkier flavor, and it won’t be as white when it cools.


During the cooking time, you will notice the fat slowly starts to render and cook. There will be a light simmer and small bubbles forming during the cooking process, but you don’t ever want a rolling boil. If your rendered fat starts bubbling too much, reduce the heat and stir well.


Straining is important. Impurities won’t taste great and can cause the tallow to spoil faster, so make sure to strain twice. The first strain is in a fine strainer to remove any large pieces, and the second uses cheesecloth, a coffee filter, or a paper towel to get all the final small pieces removed.


You can use this immediately. It will remain a liquid until cooled where it will turn solid and white. Once you have your beef tallow cooked down and strained, store it in a lidded glass jar or container in the fridge for up to 3 months. 


  1. Heat the beef fat in a large pot. Place all of your beef fat in a large 4-5 quart pot. Turn the burner on medium-low heat.

  2. Render the beef fat. Allow the fat to simmer at this low and slow temperature for 4 hours, stirring about every 30 minutes with a wooden spatula. If needed, scrape the spatula along the bottom of the pan to release any stuck on bits of fat or beef to prevent them from burning. Do not let your fat boil. Reduce heat and stir to maintain a very light simmer.

  3. Finish rendering the fat. Your tallow will be finished rendering when the fat covers most of the remaining pieces in the pan. Those pieces will be lightly browned and look crisp all over. You won't be able to see any more white or solid pieces of fat.

  4. Strain the rendered fat. Turn off the heat and allow the tallow to cool slightly. Prepare a large bowl fitted with a strainer.  Carefully pour the tallow from the pan through the strainer into the large bowl. The strainer will catch the larger pieces of crispy rendered beef.

  5. Strain again into a glass jar. Fit your glass jar with a funnel and insert either a piece of cheesecloth, a coffee filter, or a paper towel. Slowly and carefully pour the tallow from the large bowl into the funnel. This step will reduce any remaining impurities in the tallow.

  6. Use immediately or store. Your tallow is ready to use immediately, or cover with a tight fitting lid. It should be stored safely in your fridge for 3 months. Used to cook skillet potatoes, sear steaks, or roast vegetables in place of other cooking fats.
