The Renaissance of Beef Tallow

The Re-Introduction of Beef Tallow, the Original Liquid Gold

Beef tallow—the rendered fat of cattle—is currently having a massive renaissance on social media and in the culinary world. Long dismissed as an artery-clogger, it is now being embraced by chefs and skincare enthusiasts alike for its stability and nutrient density.

What Kind of Fat is Beef Tallow?

Beef tallow is a rendered animal fat. It is made by simmering the fatty tissue (especially suet, the hard fat around the organs) until the water evaporates and the impurities are strained out.

• Composition: It is a mix of approximately 50% saturated fat, 42% monounsaturated fat (the same kind found in olive oil), and about 4% polyunsaturated fat.

• Appearance: It is solid and waxy at room temperature but melts into a clear liquid when heated.

Health Benefits vs. Negatives

The Positives

• Vitamins A, D, E, K: Tallow is rich in fat-soluble vitamins. Because it is a fat, it helps your body absorb these nutrients more effectively.

• High Smoke Point (~400°F): Unlike butter or unrefined oils, tallow can handle high heat without breaking down into toxic free radicals.

• CLA (Conjugated Linoleic Acid): Tallow from grass-fed cows contains CLA, which has been linked to anti-inflammatory properties and improved body composition.

The Negatives

• High Caloric Density: Like any pure fat, one tablespoon contains about 115 calories.

• Cholesterol Concerns: While some modern research suggests saturated fat is less harmful than previously thought, most medical organizations (like the AHA) still warn that high intake can raise bad LDL cholesterol in some individuals.

• Sourcing Matters: Tallow is a storage site for an animal’s toxins. If you don’t buy grass-fed/organic, the tallow could contain pesticide residues or hormone traces.

Uses Beyond the Kitchen: The Skincare Secret

Tallow has become a holy grail in the clean beauty community. Why? Because the fatty acid profile of beef tallow is strikingly similar to human sebum (the oil our skin produces).

How it’s used in Skincare:

1. Whipped Tallow Balm: Tallow is often whipped with a little jojoba or essential oil to create a light, airy moisturizer.

2. Barrier Repair: Because it is bio-available, it sinks into the skin rather than just sitting on top, making it excellent for eczema, psoriasis, and cracked winter skin.

3. Traditional Soap: Tallow creates a hard, long-lasting bar of soap with a rich, creamy lather that isn’t as drying as some plant-based cleansers.

Other Uses:

• Candle Making: Before wax was cheap, tallow candles were the standard.

• Conditioning Leather: It’s a natural way to waterproof and soften leather boots and saddles.

Best For: The “Crispy” Factor

Did you know? Tallow is the secret to the world’s best fries. Before 1990, McDonald’s used a blend of beef tallow for their fries, which is why people remember them being better back then. It creates a crunch that vegetable oil simply cannot replicate because of how it crystallizes upon cooling. I definitely remember the fries being tastier during my McDonalds playland days. The distinct flavor profile of their fries had a wonderful unami flavor. Also, there was controversy over their fries not being vegetarian. It all makes sense now with the beef tallow. 

Rendering your own tallow is surprisingly easy, incredibly cost-effective, and makes your kitchen smell like a high-end steakhouse. Plus, it’s the ultimate zero-waste move for any home cook.

How to Render Beef Tallow at Home

Transforming “scraps” into liquid gold.

What You’ll Need:

• Beef Fat (Suet): Ask your local butcher for beef fat trimmings or suet (the hard white fat from around the kidneys). It’s often extremely cheap or even free! I often get whole steaks from Stew Leonards and have the butcher cut them up for me into 2 inch thick steaks, and I ask them not to trim any of the fat. I trim the fat off at home by myself.

• A Slow Cooker (or a heavy-bottomed pot).

• A Fine Mesh Strainer and Cheesecloth.

• Containers for storage.

The Step-by-Step Process:

1. Prep the Fat (The most important step!)

The smaller the pieces, the faster and more evenly the fat will render. Use a sharp knife to dice the fat into small cubes, or better yet, pulse it in a food processor until it looks like ground meat.

Tip: Fat is much easier to cut when it is ice-cold or partially frozen.

2. Low and Slow

Place the fat in your slow cooker on the low setting. If using a stovetop, use the lowest flame possible. Add about a half-cup of water to the bottom—this prevents the fat from scorching before it starts melting. (Don’t worry, the water will evaporate during the process. Do not put a lid on the pot.)

3. The Wait

Let it gently simmer for 4 to 6 hours. You’ll know it’s done when the solid white fat has turned into a clear, golden liquid and the remaining bits of tissue (called “cracklings”) have turned brown and sunk to the bottom or are floating on top.

4. Strain Twice

Line a fine-mesh strainer with several layers of cheesecloth. Carefully pour the hot liquid through the cloth into a clean bowl. This removes every tiny bit of protein, which is key to making the tallow shelf-stable. I use a Greek yogurt strainer.

5. Cool and Store

Pour the liquid tallow into glass jars. As it cools, it will turn from a golden liquid to a pure, creamy white solid.

Storage Tips:

• Shelf Life: Pure, well-strained tallow is very stable. It will last for 3–4 months at room temperature in a sealed jar, or up to a year (or more) in the refrigerator.

• What to do with the Cracklings: Don’t throw away those crispy brown bits left in the strainer! Toss them with a little salt—they are a delicious, crunchy snack or salad topper.
