What Is Beef Tallow?
Beef tallow is rendered (purified) fat from cattle, typically from around the kidneys and loins. It's solid at room temperature, has a high smoke point, and was the primary cooking fat in Western kitchens for centuries.
The Basics
What it is: Rendered beef fat
Texture: Solid at room temperature, similar to butter
Smoke point: 400-420°F (high, good for frying)
Flavor: Mild, slightly beefy when freshly made
Shelf life: 1 year+ at room temperature if properly rendered
How Tallow Is Made
1. Source the fat
"Suet" is the raw fat from around kidneys and loins—the highest quality source.
2. Cut into small pieces
Smaller pieces render faster and more completely.
- Stovetop: 250-300°F for several hours
- Slow cooker: Low setting for 8-12 hours
- Oven: 250°F for several hours
4. Strain
Filter through cheesecloth to remove "cracklings" (crispy bits).
5. Cool and store
Liquid tallow solidifies into a white/cream-colored block.
Historical Uses
- Primary cooking fat in American and European kitchens
- McDonald's original french fry recipe (until 1990)
- Soap and candle making
- Industrial lubricants
- Leather conditioning
Why It Disappeared
1950s-1980s: Studies linked saturated fat to heart disease. The food industry pivoted to vegetable oils, and tallow was demonized.
- Vegetable shortening (Crisco, launched 1911)
- Vegetable oils (corn, soybean, canola)
- Hydrogenated oils (trans fats)
The irony: Trans fats (the replacement) proved far more harmful than the saturated fats they replaced.
Why It's Coming Back
- Saturated fat research is being reconsidered
- Industrial seed oils are now questioned
- Interest in ancestral/traditional diets growing
- Better flavor for cooking
Carnivore and keto diets have particularly embraced tallow.
Tallow vs. Other Fats
| Fat | Smoke Point | Saturated Fat | Source |
|-----|-------------|---------------|--------|
| Beef Tallow | 400°F | ~50% | Animal |
| Butter | 350°F | ~63% | Dairy |
| Lard (pork) | 370°F | ~39% | Animal |
| Olive Oil | 375°F | ~14% | Plant |
| Ghee | 485°F | ~60% | Dairy |
Cooking With Tallow
- Deep frying (high smoke point, stable)
- Pan frying
- Roasting vegetables
- Searing meat
- Making pie crusts
McDonald's fries were legendary when made with tallow. The 1990 switch to vegetable oil is often cited as when the fries "changed."
Where to Get It
- Make it yourself from suet (butcher shops)
- Buy online (many specialty brands)
- Farmers markets (local farms)
- Some grocery stores (growing availability)
The Health Debate
Traditional view: Saturated fat causes heart disease
Current research: More nuanced; context matters
- Saturated fat (about 50%)
- Monounsaturated fat (about 42%)
- CLA (conjugated linoleic acid) in grass-fed tallow
- Vitamins A, D, E, K (fat-soluble vitamins)
The debate continues. Many now view tallow as a reasonable cooking fat, especially versus industrial seed oils.
