Understanding Ground Beef Fat Content
When you visit the meat counter at your local grocery store or butcher, you'll see different labels like 80/20, 85/15, and 90/10. These numbers represent the lean-to-fat ratio, so 80/20 means 80% lean meat and 20% fat. The higher the fat content, the more flavorful and moist the final dish will be. The tradeoff is that fattier beef will shrink more during cooking as the fat renders out. While other exotic beef like Wagyu can be exceptionally fatty, the fattiest ground beef you can typically purchase is the regular ground beef variety, which can legally contain up to 30% fat. This means a 70/30 blend is your best bet for maximum fat content.
The Source of the Fat
Where does the fat in ground beef come from? In many cases, especially for blends without a specific cut listed, it comes from a combination of leftover trimmings from various parts of the steer. For ground beef labeled with a specific primal cut, the fat content is determined by that cut. For instance, ground chuck (often 80/20) gets its fat from the shoulder and neck region, which naturally contains a good amount of intramuscular fat. Regular or generic ground beef (70/30), however, is typically a blend of these fattier trimmings.
Comparison Table of Ground Beef Fat Ratios
| Ratio (Lean/Fat) | Typical Cut Source | Best For | Flavor & Juiciness | Shrinkage |
|---|---|---|---|---|
| 70/30 | Blended Trimmings | Juicy Burgers, Chili, Meatloaf | Maximum | High |
| 80/20 | Ground Chuck | Burgers, Meatballs | Excellent | Medium |
| 85/15 | Ground Round | Tacos, Meat Sauces, Casseroles | Good | Low to Medium |
| 90/10 | Ground Sirloin | Chili, Stews, Meat Sauce | Leanest | Low |
Best Culinary Uses for Fatty Ground Beef
Don't let the high-fat content scare you away—it's what makes certain dishes exceptionally delicious. The additional fat provides a richness and moistness that leaner cuts can't match. Here are some of the best uses for 70/30 ground beef:
- Juicy Burgers: The rendered fat bastes the meat from the inside, preventing it from drying out, even when cooked well-done. The result is a richer, more flavorful patty. It's an excellent choice for classic smash burgers.
- Flavorful Chili: Using a higher fat content for chili helps create a more robust and complex flavor profile. The fat melds with the spices and other ingredients for a more satisfying result.
- Hearty Meatloaf: Meatloaf cooks for a longer period, making it susceptible to drying out. A 70/30 blend provides the necessary moisture to keep the finished product tender and flavorful throughout the baking process.
- Rich Pasta Sauces: A higher fat content helps build the base flavor of a meat sauce. While you may drain some of the excess fat, enough will remain to add depth and richness to the sauce.
Tips for Cooking High-Fat Ground Beef
Cooking with a 70/30 blend requires a slightly different approach than with leaner cuts to manage the rendered fat.
- Drain the fat: For dishes where you don't want the final product to be overly greasy, such as tacos or pasta sauce, make sure to drain the excess fat after browning the meat. A colander works well for this.
- Boil for bulk prep: For large batches, some home cooks prefer to boil the ground beef, which separates the fat easily for a less greasy result, especially useful for meal prepping.
- Mind the splatter: When pan-frying or grilling fattier beef, be prepared for more grease splatter. A splatter guard can be useful.
- Use it for binding: The extra fat can act as a natural binder, which is beneficial in recipes like meatballs or meatloaf where you want the mixture to hold together well without falling apart.
- Save the drippings: The rendered beef fat (tallow) can be saved and used for other cooking applications, adding rich, beefy flavor to roasted potatoes or other dishes.

Conclusion
While many people focus on lean ground beef for health reasons, there are definite culinary advantages to choosing a fattier option. The fattiest ground beef you can readily purchase is the 70/30 blend, often labeled as 'regular ground beef'. Its high-fat content is a secret weapon for creating exceptionally juicy burgers, rich chilis, and moist meatloaf. By understanding how to manage the rendered fat, you can harness its full flavor potential and elevate your favorite comfort food recipes.
