Fatworks Grass-Fed Beef Tallow Review: Costco 2-Packs, Organic vs Wagyu, and Our Verdict

Quick verdict: Fatworks Grass-Fed Beef Tallow is the easiest good cooking tallow to buy in the US. It is a single-ingredient, grass-fed and grass-finished tallow in a 14 oz glass jar, it sears, fries and bakes cleanly, and it is stocked at Costco and Walmart as well as online. The one real drawback is volume: 14 oz goes fast if you deep fry, so heavy fryers should pair it with a bulk tub.

Brand Background: Who Makes Fatworks

Fatworks is a Colorado-based company that has sold traditional cooking fats since long before tallow became a grocery trend. The line now covers grass-fed beef tallow, organic beef tallow, American wagyu tallow, bison tallow, duck fat and pork lard. Fatworks doesn’t raise cattle; it buys fat from US beef suppliers with grass-fed programs and renders it into jars.

A few label facts worth knowing before you buy:

• Grass-fed and grass-finished. The standard jar is sold as “100% grass-fed and finished” beef (that is how Costco’s listing describes it). Grass-fed alone can mean grain-finished; grass-finished means the animal ate grass through the end of its life, which is where most of the fatty acid differences come from. Our grass-fed vs grain-fed tallow guide covers what that does and doesn’t change.
• Organic is a separate product. The regular grass-fed jar is not USDA Organic. If you want the organic seal, buy the Fatworks Organic jar specifically.
• Whole30 Approved. The grass-fed tallow carries the Whole30 Approved mark, which matters if you follow that program.
• Phthalate testing. Fatworks’ FAQ says it actively tests its fats for phthalates and claims to be the only tallow company doing so. We haven’t seen the test data, so treat it as a company claim, but it is more than most brands disclose.

What’s in the Jar

The ingredient list is one line: beef tallow. No added seed oils to keep it soft, no rosemary extract, no preservatives. That matters because some cheaper “tallow” products are blended with other fats to change texture.

The fat is firm at room temperature, a pale cream color with a slight yellow tint. That yellow comes from carotenoids in grass, so it is a normal sign for grass-finished tallow. Paper-white tallow usually means grain-finished cattle or a refined, deodorized product. Our tallow color guide explains what different shades tell you.

Out of the jar it smells faintly beefy and a little nutty, closer to cold butter than to a roast. Once it is in a hot pan the smell mostly disappears into whatever you are cooking. Fatworks is not deodorized, so if you want tallow for balms or lotions, a deodorized base such as Traverse Bay’s 32 oz jar is the better starting point.

Kitchen Testing: Four Cooking Methods

I put Fatworks through the same home-kitchen routine I use for every cooking fat: a cast iron skillet, a Dutch oven and a standard oven.

Steak Searing

A tablespoon in a 12-inch cast iron pan, heated until it just started to shimmer, then a room-temperature ribeye. Full-contact sear, no sputtering, no acrid smoke. After four minutes per side the crust was deep and even, and the tallow added richness without competing with the beef. Tallow’s high saturated fat content is why it holds up at searing temperatures; our smoke point and temperature guide has the numbers for each cooking method.

French Fries

Standard double fry: 325°F for the blanch, rest, then 375°F to finish. The tallow melted cleanly with no foam, and the fries came out golden and crisp with the flavor people associate with pre-1990 fast food fries. The full method is in our McDonald’s-style tallow fries recipe.

After frying I strained and saved the fat. It filtered clean and I got four rounds of frying from the batch before it darkened enough to retire. If you plan to reuse fat, our guide to reusing beef tallow after frying covers straining and storage.

Eggs

A teaspoon in a preheated pan at medium heat. No smoke, no spattering, no sticking, and only a faint richness on the eggs. If nobody told you, you might guess mild butter.

Biscuits

I swapped Fatworks for butter in a buttermilk biscuit recipe: cold tallow cut into the flour, folded, rolled and baked at 425°F for 14 minutes. The biscuits were flakier than the butter version, which makes sense because tallow contains no water. The flavor stayed neutral enough for the buttermilk and salt to lead.

Cleanup

Tallow solidifies as it cools. Wipe the pan while it is still warm and everything comes off easily; wait until it is cold and you will be scraping. That is true of every tallow, not only Fatworks.

Fatworks Beef Tallow at Costco

Fatworks is the brand most shoppers find when they search for beef tallow at Costco. As of September 2026, Costco’s same-day delivery site lists Fatworks Grass-Fed Beef Tallow, 14.1 oz, 2-count and Fatworks Wagyu Beef Tallow, 14 oz, 2-count, and Costco Business Delivery lists a Fatworks 3.6 lb tub. Shoppers also report a Fatworks Organic 2 x 14 oz pack at some warehouses. Fatworks runs a dedicated Costco page on its own site for the grass-fed 2-pack.

What that means in practice:

• The Costco 2-pack is usually the cheapest way to buy Fatworks per ounce. It is the same grass-fed tallow in the same size jars.
• Stock varies by warehouse. Costco rotates pantry items, so check the Costco app or call your warehouse before a special trip.
• The 3.6 lb Business Delivery tub is the closest thing Fatworks has to a bulk size, but Business Delivery only serves certain areas.

Walmart also lists the 14 oz jar and a grass-fed 2-pack online. For every store option, including farmers markets and butchers, see our guide to finding beef tallow near you.

What We Liked

• Clean rendering. No off smells, no sediment, no soft oily layer on top of harder fat, which is a common sign of sloppy rendering in budget tallow.
• Mild flavor. Neutral enough for eggs, vegetables and baking, while still tasting like beef fat when you want it to.
• Consistency. Every jar I’ve bought looked, smelled and performed the same.
• Glass jar. Doesn’t pick up odors the way some plastic tubs do, and you can see how much is left.
• Easy to find. Costco, Walmart, Amazon and direct, so you can buy it on a normal grocery run.

What Could Be Better

• 14 ounces doesn’t go far for deep frying. A Dutch oven batch of fries can use more than a full jar. If you fry weekly, you’ll be buying jars constantly.
• No true bulk size at retail. Outside Costco Business Delivery’s 3.6 lb tub, you’re stacking 14 oz jars.
• Narrow jar mouth. Scooping solid tallow out with a spoon is awkward. Warming the jar in a bowl of hot water helps.
• Glass adds shipping weight when you order online, which can push the price up if you don’t live near a Costco or Walmart that stocks it.

Grass-Fed vs Organic vs Wagyu: Which Fatworks Jar?

• Fatworks Grass-Fed is the default. Grass-fed and grass-finished, Whole30 Approved, and the version you’ll find most often in stores.
• Fatworks Organic adds USDA Organic certification, which covers feed, antibiotics and handling rules. Cooking performance is the same. Buy it if the organic seal matters to you; otherwise the grass-fed jar is the better value. Our organic beef tallow guide compares it with other certified options.
• Fatworks American Wagyu is richer and more beef-forward. It shines on steaks and burgers and is wasted in a deep fryer. We compare wagyu tallows in our best wagyu beef tallow guide.

How Fatworks Compares

• Fatworks vs EPIC: similar jars, similar performance. EPIC is owned by General Mills, which some buyers care about. See Fatworks vs EPIC.
• Fatworks vs South Chicago Packing: SCP’s wagyu tallow is richer, and its 42 oz tub is better for frying volume. See Fatworks vs South Chicago Packing.
• Fatworks vs Cornhusker Kitchen: Cornhusker sells bulk tubs and pails that suit deep frying. See our Cornhusker Kitchen review.
• Fatworks vs Brandt: Brandt is a California ranch brand sold in 1 lb and 4 lb tubs, useful if you want more volume per purchase. See our Brandt beef tallow review.

For the full field, start with our best beef tallow for cooking roundup.

Cheaper alternative for deep frying: Cornhusker Kitchen Grass-Fed Beef Tallow, 7.5 lb. Same grass-fed category in a pail, which costs much less per ounce when you’re filling a fryer. Keep a jar of Fatworks for searing and baking and use the pail for frying.

Is Fatworks tallow organic?

Only the Fatworks Organic jar is USDA Organic. The regular grass-fed jar is not certified organic.

What does Fatworks beef tallow taste like?

Mild and slightly nutty, closer to clarified butter than roast beef. You’ll notice it most with fried potatoes and seared steak, where it tastes good.

How long does Fatworks tallow last?

Unopened jars keep for well over a year at room temperature in a dark pantry; check the best-by date on the lid. Once opened, keep it closed and away from heat, or refrigerate it to stretch shelf life. Our beef tallow shelf life guide goes into detail.

Bottom Line

Fatworks Grass-Fed Beef Tallow earns its reputation. It is cleanly rendered, grass-finished, single-ingredient tallow that performs well at every cooking task I use tallow for, and it is easy to buy, especially as a Costco 2-pack. If you cook with tallow a few times a week, buy the Fatworks grass-fed jar and you’re set. If you deep fry often, keep a jar for searing and baking and buy a bulk pail for the fryer.
