Costco Ground Beef 10 lb Tubes: Which Fat Ratio Is Right for You?

If you’re feeding a family, running a summer cookout, or doing serious meal prep, Costco’s Kirkland Signature 10 lb ground beef tubes are one of the smartest buys in the meat case. Instead of paying $7/lb at the grocery store, you’re getting bulk beef at a fraction of that — and you control exactly how much you use.

These tubes are available at Costco Business Centers and select Costco Warehouses. Here’s what you need to know before you grab one.

The Three Options, Explained

90/10 (Lean) — 90% lean, 10% fat. This is your weeknight workhorse for tacos, spaghetti sauce, stuffed peppers, or anything where you’re draining the meat anyway. It’s the healthiest pick, but it can dry out on the grill if you’re not careful. Best for: health-conscious families and high-volume meal preppers.

80/20 (The Classic) — This is the gold standard for a reason. Enough fat to keep burgers juicy on a hot grill, enough lean to not feel greasy. If you’re making smash burgers, meatballs, or meatloaf this summer, this is your tube. Best for: backyard grill masters and anyone feeding a crowd at a cookout.

73/27 (The Rich One) — More fat means more flavor, but also more shrinkage and more you’ll drain off. This is a niche buy — great for restaurant-style burgers or mixing into leaner meats for patties. Best for: cooks who prioritize flavor and don’t mind the extra fat.

Why This Deal Is Worth It in Summer

June through August is prime grilling season, and ground beef is the backbone of most backyard menus. Buying a 10 lb tube now means you can portion and freeze immediately — and you’re covered for every cookout, weeknight taco Tuesday, and last-minute dinner through Labor Day.

For Southern families especially, where feeding a big group is a regular weekend event, the per-pound savings here add up fast. You’re not just buying beef — you’re buying the flexibility to grill spontaneously without a grocery run.

What You’ll Need to Make This Work

A 10 lb tube is a commitment. To get the most out of it, portion the beef into meal-sized amounts (usually 1–1.5 lbs), press flat, and freeze in zip-lock freezer bags or vacuum-seal bags. Flat packs thaw faster and stack efficiently in the freezer. [AFFILIATE:vacuum_sealer] and [AFFILIATE:freezer_bags] are the two accessories that turn a bulk buy into an organized freezer stash.

Any Caveats?

Not every Costco carries all three ratios — availability varies by warehouse and Business Center. The 80/20 is the most widely stocked. If you’re after the 90/10 or 73/27 specifically, call ahead or check your local warehouse before making the trip.

There’s also no listed expiration on this deal — Kirkland ground beef is a staple item, not a limited-time sale. But prices can shift, so if you’re seeing a price you like, it’s worth stocking up.

The Bottom Line

For meal preppers, big families, and anyone who grills regularly, the Costco 10 lb ground beef tube is a no-brainer this summer. Go 80/20 if you’re unsure. Grab the 90/10 if you’re watching fat. Save the 73/27 for a special-occasion burger night.
