How to Render Fat from Briskets and Beef Roasts

Save your beef fat trimmings!

If you’ve ever trimmed a brisket or a well-marbled beef roast, you’ve probably ended up with a small pile of beautiful beef fat. Please, don't toss it! Save it and make something useful! Rendering beef fat (also known as tallow) is easy, rewarding, and a great way to stretch your beef dollar and make the most of every cut. Plus, homemade tallow from homegrown pasture-raised beef is unmatched when it comes to cooking, frying, or even making homemade candles and soaps!

What You’ll Need:

• Beef fat trimmings (from brisket, chuck roast, or any well-marbled cut of dry-aged beef)

• A sharp knife

• A heavy-bottomed pot or slow cooker

• A fine-mesh strainer or cheesecloth

• Good old-fashioned canning jars for storage

Step 1: Trim and Save the Fat

When you’re prepping a brisket or roast before cooking, take a few extra minutes to trim off any large pieces of white, firm fat. Avoid pieces with too much meat attached (a little is fine, but you want mostly fat). Instead of throwing it away, start a quart-sized bag in your freezer and keep adding to it every time you trim a roast. Before you know it, you’ll have enough to render a nice big batch—no waste, just pure, useful tallow!

When you’re ready to render, cut the frozen fat into small chunks or, for best results, run it through a food processor for finer pieces. The smaller the pieces, the quicker and more evenly they’ll render down.

Step 2: Start the Rendering Process

If the pieces are smaller, it's ok to just put it straight into your pot.  If your fat is bigger, or from our kidney suet nuggets, it might be worth running it through your meat grinder with a coarse plate, it makes the process so much faster!

Place the fat into a heavy-bottomed pot or slow cooker. Turn the heat to low—slow and steady is key! As the fat melts, it will separate into golden liquid tallow and crispy bits called cracklings. Stir occasionally to prevent sticking and burning.

Step 3: Strain and Store

Once the fat is fully melted and the cracklings are golden brown, remove from heat. Line a fine-mesh strainer with cheesecloth and carefully pour the hot liquid through it into clean canning jars. This helps remove any small bits, leaving you with smooth, pure tallow. Let it cool at room temperature before sealing and storing.  

If you love really pure fat, repeat this step 2 additional times.

How to Use Rendered Beef Fat

• Cooking & Frying: This is my secret little starting step for recipes—I love frying onions and garlic in beef fat before I really get going. It also works wonders for roasting veggies, searing steaks, or frying potatoes.

• Baking: Tallow makes amazingly flaky pie crusts and biscuits.  Matched, only by butter, in my opinion!

• DIY Projects: We have customers who make beef fat into candles, soap, or even skin balms.  Sky is the limit, I love to hear what you plan to do, send me a note!

Bonus: Don’t Waste the Cracklings!

Those crispy little bits left behind? That’s beef cracklings, and they’re delicious! Sprinkle them with salt and enjoy as a snack or use them as a topping for salads and soups. Joshua loves these!

Give it a Try!

Rendering beef fat is a versatile way to get the most out of your dry-aged, homegrown Wisconsin farm beef while creating a flavorful, useful cooking fat. Keep that freezer bag going, save every bit, and you’ll always have a stash ready to go. Give it a try the next time you’re trimming beef—you’ll never look at fat the same way again!
