What Is Tri Tip? The Cut, Grades, and Buying Guide

What Is Tri Tip?

Tri tip comes from the bottom sirloin, at the hip where the loin meets the round, just ahead of the flank. It’s a single muscle (the tensor fasciae latae, IMPS 185C untrimmed) that does real work during the animal’s life, enough to develop deep, beefy flavor, but it’s not as heavily exercised as the round or the shank, so it stays tender enough to grill hot and fast or smoke low and slow. That balance is what makes it special. A whole, untrimmed roast runs 2½ to 4 pounds and trims to 1½ to 2½, with enough marbling to stay juicy over high heat without needing the low-and-slow treatment that fattier cuts demand.

Each steer produces exactly two tri tips, one per side. That relative scarcity, combined with the fact that most of the country didn’t even know the cut existed until recently, kept tri tip a California secret for decades.

A California Original

The culture of cooking beef over red oak fires on the Central Coast goes back to the Spanish-era ranchos of the 1800s. Vaqueros and rancheros would butcher cattle and roast large cuts over pits of red oak coals for community gatherings, one of the oldest regional barbecue traditions in the country.

The cut we call “tri tip” got its modern name in the 1950s, most commonly attributed to Bob Schutz, a butcher at the Santa Maria Safeway who later owned the Santa Maria Market, who began marketing the triangular roast by name rather than grinding it into hamburger. The Santa Maria Valley ran with it. Local ranchers, butchers, and grill cooks refined the technique: season simply with salt, pepper, and garlic, cook over red oak, slice against the grain, and serve with pinquito beans, salsa, and garlic bread.

For most of the 20th century, tri tip was nearly impossible to find outside California. Butchers in the rest of the country broke the bottom sirloin into different cuts or ground it. That’s changed. Today tri tip has a national following, but the heart of the tradition is still the Central Coast. For the full story, see our Santa Maria BBQ history.

Anatomy of the Cut

Understanding the physical shape of a tri tip helps you cook it better and slice it correctly.

The Triangle Shape

Tri tip is roughly triangular with three distinct corners: a thick end (the “heel”), a thin tapered point, and a middle corner. The thick end can be nearly twice as thick as the point, which is why managing heat zones matters during the cook. The thick end will finish medium-rare while the thin end runs closer to medium, a feature, not a bug, since it gives you slices at different doneness levels to serve everyone at the table.

The Grain

Tri tip has a grain that changes direction roughly through the center of the cut. The fibers run one way on the thick end and arc in a different direction toward the point. This is the single most important thing to understand about tri tip. If you slice with the grain instead of against it, even a perfectly cooked tri tip will be chewy. The solution: cut the roast in half roughly through the middle where the grain shifts, then slice each half perpendicular to its own grain direction.

The Fat Cap

One side of the tri tip is covered by a layer of fat, the fat cap. Some cooks leave it on for moisture and flavor, trimming it down to about ¼ inch. Others remove it entirely so the rub makes direct contact with the meat. Both approaches work. If you’re smoking, the fat cap helps protect the meat during the long cook. If you’re grilling hot and fast, trimming it off gives you a better sear and crust.

What to Look for at the Counter

Marbling

Look for even white flecks of intramuscular fat distributed throughout the meat. Good marbling means the fat renders during cooking and bastes the meat from the inside, keeping it juicy. Avoid cuts that are very lean with almost no visible fat. They’ll dry out quickly, especially at higher temperatures.

Color

Fresh tri tip should be a deep, rich red: not brown, not gray, not bright cherry red (which can indicate gas packaging). A slight purple tint from vacuum packaging (cryovac) is normal and will bloom to red once exposed to air for 15 to 20 minutes.

Size and Thickness

A good trimmed tri tip for the grill runs 2 to 2½ pounds and is at least 2 inches thick at the heel. Anything under 2 pounds has likely been over-trimmed, which means less fat, less moisture, and less margin for error. If you have a choice, go bigger. A thicker roast gives you more control over internal temperature and a better crust-to-center ratio. Plan on half a pound of trimmed roast per person; the serving calculator scales that to any head count.

The Silver Skin

Check the non-fat-cap side of the tri tip for silver skin, a thin, translucent membrane of connective tissue. It doesn’t render or break down during cooking and will make the surface tough and chewy. A good butcher will have removed most of it, but if you see patches, peel them off with a sharp knife before seasoning.

USDA Grades

Beef grading is based primarily on marbling and the maturity of the animal. For tri tip, grade matters.

Select is the leanest grade you’ll see at the store. Minimal marbling. It dries out fast over high heat, which makes it a poor choice for grilling a whole roast. Fine for thin-slicing after a slow cook, but that’s not what most people are here for.

Choice is the sweet spot. Enough intramuscular fat to stay juicy through a hot grill or a long smoke, and it’s what most quality butchers and grocery stores carry. If you’re cooking tri tip regularly, this is your grade.

Prime is noticeably richer, with more marbling meaning more rendered fat basting the meat from the inside. It’s harder to find and costs more, but it’s also more forgiving. If you pull it five degrees late, Prime still eats well. Worth seeking out for a special cook.

Wagyu and American Wagyu are a different animal, almost literally. The fat content is high enough that the texture changes: richer, softer, almost buttery. Cook it gently and pull it early. Wagyu tri tip at 140°F is a waste of money. For target temperatures by doneness, see tri tip internal temp.

Where to Buy

The Butcher Shop

Your best bet. A good butcher can source specific grades, cut to your preferred size, and trim to order. Ask for an untrimmed or lightly trimmed whole tri tip so you have control over the fat cap. Build a relationship. Butchers who know you’ll come back tend to set aside better cuts.

Grocery Stores

Major chains in California stock tri tip year-round. Outside California, availability varies. Costco consistently carries Choice tri tip at a good price-per-pound and the quality is reliable. Look for cryovac-packed whole roasts rather than pre-trimmed or pre-seasoned cuts, which often use lower-grade meat.

Online

Several ranches and online butchers ship tri tip nationwide. This is the best option if you want Prime or Wagyu and don’t have a local source. Expect to pay more for shipping, but the quality can be outstanding. Snake River Farms, Porter Road, and Crowd Cow are reputable options, among others.

Direct from Ranches

If you’re in California, buying direct from a ranch, especially on the Central Coast, gets you the freshest meat with full traceability. Many ranches sell individual cuts at farmers’ markets or through their own websites. You’ll know exactly where the beef came from, how it was raised, and when it was processed.

What Should It Cost?

Tri tip isn’t the bargain it once was. In California right now, Choice runs about $6.99 a pound and branded Angus closer to $9.24, and nationally the average is up roughly 46% since 2019. Advertised prices dip hardest around grilling-season feature weeks, so timing your buy pays off.

Prep Before the Cook

How to Trim Tri Tip: Trimmed vs. Untrimmed

Tri tip sells two ways. Trimmed (what most grocery counters carry) has the fat cap taken down to a thin layer and the silver skin off. Untrimmed (the warehouse-club and butcher-case version, often labeled “peeled” when the butcher has removed only the membrane) still wears a fat cap that can run close to an inch thick. Untrimmed is cheaper per pound and you lose about a fifth of the weight on the board, more with a heavy cap, so the price gap is smaller than it looks. Buy untrimmed if you want control over the cap and don’t mind ten minutes with a knife.

How much fat to leave depends on the cook. For smoking or any long indirect cook, trim the cap to about ¼ inch so it renders without shielding the meat from smoke. For hot direct grilling, go thinner or remove it entirely; a thick cap over coals just flares and chars. Remove the silver skin from the underside every time. It is a tough, shiny membrane that never renders, and it shrinks as it heats and curls the roast. Slide a thin knife under one end, angle the blade up, and pull the skin against it. Trim any loose flaps or the thin tail that would burn before the heel is done.

Fat side up or down is the other question, and on the trimmed roast most grocery counters sell it is close to moot: there is barely a cap left to orient. Our own preference is to take the cap off entirely so the seasoning sits on meat, not fat. If you do have a real cap, both camps are legitimate. Cap toward the fire during the sear renders and crisps it, and on a Santa Maria grill the grate sits far enough from the coals that flare-ups are manageable, though you still have to watch it. Cap up keeps the fat on top, where it renders over the surface through the indirect finish or the smoker.

What a thick cap guarantees over direct heat is dripping fat and flare-ups, so if yours is untrimmed, keep the roast movable and slide it off a flame rather than wait one out.

Temper the Meat

Pull the tri tip from the fridge 45 minutes to an hour before cooking. A room-temperature roast cooks more evenly than a cold one straight from the fridge. This is especially important for thicker cuts where the temperature gradient from surface to center is more pronounced.

Dry Brine

For the best results, salt the tri tip generously with kosher salt the night before and leave it uncovered on a wire rack in the fridge. The salt draws moisture to the surface, dissolves, and is reabsorbed into the meat, seasoning it deeply and improving the texture. The uncovered fridge time also dries the surface, which means a better sear and crust. If you want a full seasoning blend instead of straight salt, see the rub.
