Best Beef Bones for Bone Broth: A Buyer's Guide

The best beef bones for bone broth are knuckle, marrow, oxtail, and neck. Anchor the pot in knuckle for the gel (about 70% by weight). Fill the rest with marrow, neck, and oxtail for fat and flavor. Roast first, simmer at least twelve hours, and the broth tastes like it cooked for two days. Because it did.

We don't sell bones. We simmer a lot of them, though, so this is what we ask for at our butcher.

The Four Bones Worth Asking For

Four bones do most of the work in a beef broth. The other cuts you'll see at the butcher are fine but redundant.

Knuckle

Joint bone, mostly cartilage and connective tissue. The collagen workhorse and the reason your broth gels. Most underrated cut at the butcher counter, hands down. If you've never made broth before, this is the bone to start with. You'll learn more from a knuckle-only batch than from any guide. Knuckle alone won't give you a beautiful broth, but it will gel, and that gel is the proof you ran the simmer right.

Marrow

Femur or tibia cross-sections, mostly fat and marrow inside hollow bone. Adds richness and the golden fat layer that rises when the broth cools. Mouthfeel changes too: silkier, more coating. Don't overdo it. Marrow is fat, not collagen. A marrow-heavy pot makes a glossy broth that pours liquid in the fridge, not a jiggly one.

Oxtail

Tail vertebrae with meat, fat, and joint material in one cut. The all-rounder. If you only had one cut to choose from, oxtail would do most of the work that the other three bones do separately. Doubles as a soup ingredient if you don't strain too aggressively. The downside is cost: oxtail runs $7-12/lb, sometimes higher at specialty butchers, where knuckle and marrow run closer to $4-6/lb.

Neck

Vertebrae with meaty bits and joints. Cheaper than oxtail for similar collagen-and-meat balance. Underrated, often overlooked at the counter because butchers don't always display them. Worth asking for by name. The full list of beef cuts for the pot covers the broader survey, including cuts for braising and roasting.

How to Mix Them: Anchor in Knuckle

The buyer's actual decision is how many of each. Anchor in knuckle, fill the rest.

Anchor: knuckle, about 60-70% by weight. It's the bone that makes broth gel. Almost pure cartilage and connective tissue, very little fat. Without enough knuckle, the broth doesn't set firm in the fridge no matter how long you simmer.

Marrow rounds: about 10-20%. Marrow is fat, not collagen. It contributes the golden top layer and richness, but it does not contribute to the gel. Overload the pot with marrow rounds and you get a glossy broth that sits liquid in the fridge.

Neck and oxtail: about 20-30%. Both are vertebrae with meat, fat, and joint material. They bring meatiness, body, and depth. Neck is the budget option; oxtail is the special-occasion upgrade.

For an 8-quart pot, that works out to roughly 3 lbs knuckle plus 1 lb marrow rounds plus 1 lb mix of neck and oxtail. The exact split shifts depending on what your butcher has. Knuckle is the constant.

And yes, we love a good knuckle bone! The whole post is built around them for a reason.

The Buyer's Checklist: 5 Things to Check Before You Hand Over the Money

1. Source. 100% grass-fed means more developed marrow and a richer flavor base. The bones are denser too. Pasture-raised is the floor; 100% grass-fed is the upgrade. For beef specifically, the label should say "100% grass-fed" or "grass-fed and grass-finished." If it just says "pasture-raised," the cattle may have been finished on grain.
2. Cut visibility. You want to see joint cartilage on knuckles, intact marrow filling the hollow on marrow bones, and meat still attached on oxtail and neck. Bare-stripped bones have less to extract.
3. Color and freshness. Fresh bones are pink-to-red, not gray or brown. Marrow should be firm and white-to-pink, not melted-looking or oxidized.
4. Cut size. 2-3 inch cuts on knuckles and marrow simmer evenly in a stockpot. Whole knuckles take longer and don't release as much. Ask for them halved if they aren't already.
5. Ratio in the pack. If you're buying a pre-portioned "broth pack" online, check the mix. Some are all marrow (pretty in photos, weak gel). Some are all knuckle (great gel, no fat). Make sure knuckle is the dominant cut.

Two more things worth knowing before you go:

• Price reality. At a real butcher counter, expect $4-6/lb for knuckle, $4-7/lb for marrow rounds, and $7-12/lb for oxtail. Specialty grocers and pasture-raised DTC run higher across the board. If a butcher quotes you "oxtail prices" for plain neck bones, walk. (And yes, you can walk in and ask, "What are these going for per pound?" That's the conversation.)
• Avoid the dog-treat shelf. Smoked, seasoned, or pre-roasted "soup bones" sometimes turn up at grocery stores marketed for chewing or as flavor packs. Skip them. Smoke and seasoning will dominate everything you simmer for 18 hours. Stick to raw, unseasoned cuts.

Where to Buy Them: Three Honest Paths

Once the buyer's checklist makes sense, the question is where to actually buy. There are three real options.

Your Local Butcher (Best for Quality)

Most cooks skip this step. Don't. Real butcher counters often keep the best knuckles in the back for their own stock or for restaurant accounts. The trick is to ask specifically: "Do you have any spare knuckles or joint bones today?" Specific terms get you to the good cuts. Most butchers will halve a whole knuckle for free if you ask. Cheaper, fresher, and you can specify cut size at the counter. Often half the price of online.

Online (Pasture-Raised DTC Farms)

If you're not in a city with a real butcher, this is your move. Best for grass-fed sourcing where local options fall short. Brands worth knowing: White Oak Pastures, US Wellness Meats, Crowd Cow, Force of Nature, Wild Harmony Farm. Most ship in 2-5 lb packs of single-cut or pre-mixed "broth packs." Read the cut breakdown before ordering. White Oak Pastures, for example, sells pasture-raised beef knuckle bones and marrow bones in 2.5 lb packs.

Grocery Store (Use It as a Backup)

This one is highly variable. Whole Foods and some specialty grocers carry beef bones, often only marrow rounds. Conventional grocery carries less, and quality varies. If you're trying to get in the habit of making broth, this might be too variable of a source.

If you find yourself sourcing bones regularly, the butcher path scales best on cost. The DTC path scales best on quality. The grocery path generally scales worst on both. You can make demi-glace from those bones once you have a steady supply, but the first batch is always going to be a butcher conversation. That said, one of the Market Baskets that I frequent seems to always have a great supply of bones at great prices.

How Much Bone for How Much Broth?

A compact reference for the cook checking the post mid-shop. Numbers below assume a 12-18 hour bare simmer (180-185°F) with the lid partially open.

Pot size	Total bone weight	Approx. yield (cups)
6 quarts	2-3 lbs	6-9
8 quarts	4-5 lbs	9-13
12 quarts (proper stockpot)	6-8 lbs	14-20
16 quarts	8-10 lbs	18-26

About reduction: beef broth simmered partially covered for 12-24 hours loses roughly 25-40% of starting water volume to evaporation, depending on lid gap, pot width, and how hot you run the simmer. That reduction is what concentrates the collagen into a gel (Cleveland Clinic's bone broth page covers the basics of how collagen breaks down into gelatin during the long simmer). Don't constantly top off the pot, or you'll dilute exactly the body you're trying to build. Start with water about 2 inches above the bones, partial-cover the lid (leave roughly a third of the opening uncovered), and accept the reduction as the price of admission.

For the full method, the crock-pot stock recipe walks through it.

Common Questions

Are beef knuckle bones the best for bone broth?

For collagen, yes. Knuckles are nearly all joint cartilage and connective tissue, which break down into gelatin and give your broth its gel. But knuckle alone is one-note. Mix with marrow and oxtail for body and flavor.

What's the difference between marrow bones and knuckle bones for broth?

Marrow bones contribute fat, richness, and that golden top layer. They do not gel. Knuckle bones contribute collagen and the gelled-when-cold body. A good broth anchors in knuckle (about 60-70% by weight) and rounds out with marrow rounds, neck, and oxtail.

Can I use just oxtail for bone broth?

Yes, and it makes excellent broth. Oxtail is the all-rounder, with joints, meat, and marrow in one cut. The downside is cost: oxtail runs $7-12/lb vs. $4-6/lb for knuckle and marrow bones. Worth it for special batches; expensive as the everyday move.

How many pounds of beef bones do I need for a gallon of broth?

For one gallon (16 cups) of finished broth, plan on 6 to 8 pounds of bones in a 12-quart stockpot. Beef broth loses roughly 25-40% of starting volume to evaporation over a 12-24 hour simmer (depending on lid gap and heat), so the math is about 2 cups of starting water per cup of finished broth. Anchor the bones in knuckle no matter the batch size.

Should I roast beef bones before making broth?

Yes for beef. Roast at 400°F for 30-45 minutes until deeply browned before simmering. Roasting builds the deep, savory color and flavor that's the whole point of beef broth. Skip the roast and you'll get a pale, weak broth. Chicken bones can go straight into the pot; beef should not.

The Cook's Take

Four bones, anchored in knuckle, three places to find them. That's the whole post.

Good bones make broth that gels in the fridge and turns up in everything you cook for the next two weeks. Risotto, braises, the splash that makes Tuesday's pasta sauce taste like Sunday's.

We start with the same logic. Pasture-raised, 100% grass-fed beef bones from family farms. Simmered as long as it takes to gel. Then reduced all the way down to demi-glace. If you want to skip the simmer, that's where we live.
