🥩 Best Meat Ratio for Burgers

SEO Guide  Updated June 2026

The number on the ground beef package — 80/20, 85/15, 90/10 — is the ratio of lean meat to fat, and it matters more than almost anything else for how your burger turns out. For most burgers, 80/20 is the answer. Here's why, and when to choose something else.

What the numbers mean

"80/20" means 80% lean meat to 20% fat by weight. Fat is flavor and juiciness — it bastes the meat from the inside as it cooks and carries much of the beefy taste. Too little fat and the burger is dry and crumbly; too much and it shrinks dramatically and can fall apart.

Why 80/20 is the sweet spot

80/20 ground chuck hits the balance: enough fat for a juicy, flavorful burger and enough structure to hold its shape and form a great crust. It's the standard at most good burger restaurants for a reason. If you buy one kind of ground beef for burgers, buy this.

When to choose a different ratio

• 85/15: A bit leaner, still good. Fine if that's what's available.
• 90/10: Too lean for most burgers — they turn out dry. Better for things like meatballs or tacos where added moisture helps.
• 70/30: Very rich; great for smash burgers where the fat crisps the edges, but it shrinks a lot.

The cut matters too

Ground chuck (from the shoulder) is the all-rounder. Brisket adds deep beefy flavor and fat. Short rib is rich and luxurious. A blend of chuck + brisket (and a little short rib) is the classic "steakhouse burger blend." For everyday burgers, plain 80/20 chuck is excellent.

Grind it fresh if you can

Freshly ground beef tastes noticeably better and you control the cut and fat. If you have a grinder or a food processor, grind chilled chuck yourself. Otherwise, ask the butcher to grind chuck to 80/20.
