One cooked ounce of steak tends to give about 6–8 grams of protein, with leaner cuts landing toward the higher end of that range.
If you count macros or just want to know what you are getting from a steak dinner, the grams of protein per ounce matter a lot. Steak feels simple on the plate, yet different cuts, thicknesses, and cooking styles change the numbers in small but real ways. Once you know the typical range per ounce, planning portions stops feeling like guesswork.
This article walks through average protein per ounce of steak, how much that varies by cut, and how cooking changes the picture. You will also see how a steak portion fits into daily protein needs and how to enjoy beef while still keeping an eye on long-term health.
Steak Protein Basics In Simple Terms
Protein in steak comes from muscle tissue. When beef cooks, water leaves the meat and the piece shrinks, which makes each cooked ounce hold more protein than the same weight of raw beef. That is why nutrition labels and databases usually list values either per 100 grams cooked or per serving such as 3 ounces cooked.
Across common lean steaks, cooked values cluster in a fairly tight band. Data drawn from beef nutrition tables based on USDA FoodData Central show cooked beef landing around 25–30 grams of protein per 100 grams, depending on the cut and fat level. On a per-ounce basis, that works out to roughly 7–8 grams of protein in each cooked ounce of lean steak, with fattier steaks sitting a little lower in that range.
One detailed listing for cooked, broiled top sirloin (lean only, trimmed to 1/8 inch fat) gives about 8.3 grams of protein in a single cooked ounce, which sits at the high end of what you are likely to see for steak on the lean side of the spectrum, and reflects underlying USDA data shared through hospital nutrition tools.
How Much Protein Per Oz Of Steak By Cut
Even though the range for steak protein per ounce is fairly narrow, small differences still matter if you eat beef often. Leaner cuts pack in more protein per ounce because less of the weight comes from fat. Fattier cuts feel richer, yet they bring slightly fewer grams of protein for the same cooked weight.
Average Protein Per Ounce Across Popular Steaks
The numbers below use cooked values for common steaks, rounded to keep them easy to remember. Real lab data vary a little from brand to brand and from steak to steak, but these estimates land in the same ballpark as major nutrition databases built from USDA testing.
| Steak Cut (Cooked, Trimmed) | Protein Per Ounce (g) | Fat Per Ounce (g) |
|---|---|---|
| Top Sirloin, Lean Only | 8.3 | 1.4 |
| Tenderloin/Filet Mignon | 7.8 | 3.0 |
| Flank Steak, Lean Only | 7.9 | 2.9 |
| Strip Steak (New York Strip) | 7.5 | 3.5 |
| Ribeye Steak | 7.1 | 4.5 |
| Skirt Steak | 7.3 | 4.0 |
| T-Bone/Porterhouse, Lean Only | 7.3 | 3.8 |
| 80/20 Ground Beef Patty | 6.5 | 5.7 |
Top sirloin and flank sit near the top for grams of protein per ounce, while cuts with more visible marbling, like ribeye and some strip steaks, trail a little behind. A classic 80/20 burger patty drops further, since more of each cooked ounce comes from fat rather than protein.
Raw Steak Versus Cooked Steak Numbers
Many people compare a raw steak on a scale at home with a cooked nutrition chart online and wonder why the figures do not line up. The answer is simple: cooking drives off water. When a steak loses liquid, the cooked piece weighs less, yet nearly all of the protein stays behind. That means protein per ounce rises after cooking even though total protein in the steak stays roughly the same.
A raw steak that weighs 6 ounces may shrink to 4½–5 ounces after cooking. If that raw steak held 40 grams of protein in total, the cooked steak still carries close to those 40 grams, just packed into fewer ounces on the plate. Thinking in terms of cooked ounces helps you match real plate portions to the numbers you see in tables.
How Cooking Style Changes Protein Per Ounce
Grilling, broiling, pan-searing, and sous-vide cooking all start from the same muscle tissue, yet they dry the surface at different rates. High heat with strong air flow removes more water and tightens the fibers. That slightly raises protein per ounce, though it does not change the total grams of protein in the steak by much.
Doneness Level And Moisture Loss
A rare steak holds more water, so each cooked ounce weighs a bit more with fewer grams of protein. A well-done steak is drier and denser, so each ounce includes more protein and more fat. The differences show up when you weigh each slice, but the steak as a whole still holds close to the same protein it had when you started cooking.
If you track macros closely, pick one doneness level that you enjoy and stick with it for your calculations. That keeps your personal estimates consistent from meal to meal, even if the lab numbers you see in tables were tested at a slightly different cooking point.
Trimmed Fat Versus Fat Left On
Another factor is trimming. A steak trimmed to “lean only” before cooking contains less external fat and more lean tissue per ounce. When that steak cooks, each ounce ends up with more protein and less fat. When extra fat stays attached, the final ounces on your plate bring more energy and slightly fewer grams of protein.
Nutrition tools that pull from USDA data often let you choose between “lean only” and “lean and fat.” For example, an entry for broiled top sirloin lean only at one ounce cooked lists around 8.3 grams of protein, while versions that include more fat land lower. Checking which option you picked helps you match your own trimming style at home.
How Steak Protein Fits Daily Protein Targets
To place steak protein in context, it helps to know common daily protein targets. The U.S. Food and Drug Administration uses a Daily Value of 50 grams of protein per day on nutrition labels for a 2,000-calorie diet, which helps shoppers compare products on the same scale, regardless of their own calorie needs.
Health writers at Harvard Health explain that the Recommended Dietary Allowance for protein sits at 0.8 grams per kilogram of body weight for the average adult, which translates to about 0.36 grams per pound. Under that rule of thumb, a person who weighs 70 kilograms (around 154 pounds) would aim for about 56 grams of protein per day from all sources combined.
Now plug your steak into that picture. A 3-ounce cooked portion of lean steak at roughly 7–8 grams of protein per ounce gives around 21–24 grams of protein. That single portion covers a bit under half of the 50-gram Daily Value and somewhere around one-third to two-fifths of the needs for a 70-kilogram adult under the Harvard formula. Regular steak eaters can reach daily targets easily, which is why many experts nudge people toward balance and variety in protein sources.
Health Balance: Steak Protein And Red Meat Intake
Steak brings more than protein. It also brings iron, zinc, vitamin B12, and other nutrients that matter for energy levels and muscle function. At the same time, red meat intake has been linked in many large studies to higher heart disease risk, especially when portions are large and intake is frequent across the week compared with diets that lean more on plant protein or fish.
Guidance from heart health and nutrition groups encourages limiting red meat and rotating in other protein options such as beans, lentils, fish, eggs, and dairy. That way you still benefit from the protein and micronutrients in beef, yet total saturated fat and processed meat intake stay in a more moderate range across the week.
From a practical angle, that can mean planning steak nights once or twice per week, choosing leaner cuts most of the time, and pairing your steak with vegetables, whole grains, and plant protein sides. That mix still leans on steak for dense protein per ounce but keeps your overall eating pattern varied.
Planning Portions: From Ounces To Plates
Kitchen scales help, but most people rely on visual cues. A classic “deck of cards” visual matches about 3 ounces of cooked steak for many cuts. A large palm or a smartphone-sized piece can land in the 4–6 ounce range. Once you tie those visuals to grams of protein, your plate starts to tell you a clearer story.
The table below takes the average protein per ounce from lean and fattier steaks and converts it into full portions. Lean steaks here assume around 7.5 grams of protein per ounce, while fattier options sit around 6.5 grams per ounce.
| Cooked Portion Size | Lean Steak Protein (g) | Fattier Steak Protein (g) |
|---|---|---|
| 2 oz (small taste) | 15 | 13 |
| 3 oz (deck of cards) | 23 | 20 |
| 4 oz (small palm) | 30 | 26 |
| 6 oz (restaurant plate) | 45 | 39 |
| 8 oz (large steakhouse cut) | 60 | 52 |
With these numbers, you can glance at a plate and judge how much protein you are taking in from steak alone. A big steakhouse cut at 8 ounces cooked can bring more than a full day’s listed Daily Value for protein, while a smaller home portion around 3–4 ounces leaves plenty of room for protein from yogurt, eggs, beans, fish, or other foods over the rest of the day.
Practical Tips For Tracking Steak Protein
First, decide whether you want to think in raw or cooked weights. If you prep freezer packs ahead of time, weighing raw steaks is convenient. If you log meals at the table, cooked weights make more sense. Pick one method and stick with it inside your own tracking app so that your numbers stay consistent even when the steak changes.
Second, match cut and fat level when you look up values. A nutrition entry for “top sirloin, separable lean only, cooked, broiled” will not match a ribeye cooked in a lot of butter. When you know the cut, trimming style, and cooking method, you can select a database entry that lines up with what is on your plate.
Third, keep an eye on the rest of the meal. Potatoes cooked in oil, creamy sauces, and rich desserts can easily push a steak dinner past your overall energy target even when your protein intake lands right where you want it. On the flipside, pairing a modest steak with vegetables, a whole grain side, and maybe a legume salad turns that protein-dense center of the plate into part of a balanced day of eating.
Pulling It Together
Once you know that one cooked ounce of steak usually brings 6–8 grams of protein, the math gets much easier. A modest steak at home may give a third of your daily protein needs, while a steakhouse portion can supply nearly all of it before you add anything else. Lean cuts like top sirloin or flank place more protein in each ounce, while richer cuts trade a bit of protein density for flavor and tenderness.
Use the tables and ranges here as working numbers, then adjust based on the exact cuts, cooking methods, and portion sizes in your own kitchen. Over time you will get a feel for how many grams of protein ride along with each steak on your menu, which makes it far simpler to enjoy beef while still hitting your nutrition and health goals.
