A 4-ounce cooked beef ribeye steak provides about 33 grams of protein; per ounce of ribeye you get about 8 grams of protein.
Beef ribeye is prized for rich flavor and solid protein in a steak that stays tender. This guide breaks down beef ribeye steak protein by serving size, trim, and cooking. You’ll see quick numbers for common portions, why cooked weight looks “denser” than raw, and where ribeye sits next to leaner beef cuts.
Quick Protein Numbers For Cooked Ribeye
The figures below use cooked, grilled ribeye filet (separable lean only, 0" trim). The data trace back to FoodData Central entries compiled by MyFoodData, which is a handy public front end that cites the USDA set.
Protein In Cooked Ribeye By Serving Size
| Serving | Protein (g) | Source Basis |
|---|---|---|
| 1 oz (28 g) | ~8.3 g | Cooked, grilled ribeye filet |
| 3 oz (85 g) | ~25 g | Cooked, grilled ribeye filet |
| 4 oz (113 g) | ~33 g | Cooked, grilled ribeye filet |
| 6 oz (170 g) | ~50 g | Cooked, grilled ribeye filet |
| 8 oz (227 g) | ~66 g | Cooked, grilled ribeye filet |
| 100 g | ~29–30 g | Cooked, grilled ribeye filet |
| 1 fillet (129 g) | ~38 g | Cooked, grilled ribeye filet |
Where do these figures come from? A typical cooked ribeye filet shows about 37.9 g protein per 129 g cooked piece, which scales to roughly 29–30 g per 100 g and about 8 g per ounce. You can check the exact entry on MyFoodData’s ribeye page, which links to the underlying USDA record.
Beef Ribeye Steak Protein By Cut And Cook Level
Ribeye sits in the “loin/rib” family. The center “eye” is marbled and tender. The “cap” (spinalis) is even richer. Trim level and which muscle you eat shift fat more than protein, yet protein per cooked ounce still lands near the same ballpark across lean-only servings. Cook level matters for moisture loss: the drier the steak, the more protein per cooked ounce because water leaves the meat.
Why Cooked Weight Looks Higher In Protein Density
Raw meat holds more water. Heat drives moisture out, so the steak weighs less after cooking. The total protein in that steak doesn’t vanish; it’s simply packed into fewer grams of cooked meat. The USDA cooking yields tables show how moisture and fat shift with heat and trimming. That’s why a cooked 3 oz portion can list ~25 g protein while 3 oz raw shows a lower number.
Trim, Bone, And Cap Vs Center
- Trim level: “Separable lean only” removes outer fat before analysis. This raises the share of protein per gram compared with a slice that includes rim fat.
- Bone-in vs boneless: Protein is measured on the edible portion. Bone adds weight at the scale, not protein to the plate.
- Cap vs center: The cap carries more fat. The protein per ounce of lean-only edible portion stays strong, yet a full cap slice with attached fat will show lower protein per total ounce.
How Many Grams Of Protein Are In Raw Ribeye?
Raw lean ribeye sits near ~20–22 g protein per 100 g, which is about 6 g per ounce. FoodData Central entries for raw ribeye cuts fall in that range, with slight swings by grade, muscle, and trim. The point stands: raw looks “lighter” on protein by weight because of the higher water content.
Raw Versus Cooked: Protein Snapshot
Use this table to see typical raw vs cooked density. The cooked line assumes grilled, lean-only portions.
Protein Density: Raw Ribeye Vs Cooked Ribeye (Per 1 oz)
| State | Protein (g/oz) | Notes |
|---|---|---|
| Raw, lean-only | ~6.0–6.5 g | Higher water; varies by cut/grade |
| Cooked, lean-only | ~8.0–8.5 g | Moisture loss concentrates protein |
| Cooked, with rim fat | ~6.5–7.5 g | Visible fat lowers protein per ounce of steak |
| Cap-heavy slice | ~6–7 g | Richer fat band, less protein per ounce |
| Center-eye slice | ~7.5–8.5 g | Moderate marbling, steady protein density |
| Very well done | ~8.5–9 g | More moisture loss per ounce cooked |
| Rare to medium | ~7.5–8.3 g | Less moisture loss per ounce cooked |
How Ribeye Compares To Other Beef Cuts
Straight protein per cooked ounce is strong across steaks. The spread tends to show up when fat and calories enter the picture. Leaner cuts like top round, eye of round, and many sirloins often post similar protein per 3–4 oz cooked, yet with fewer calories because of less fat. That’s why you’ll see weight-room menus lean into sirloin or round for tighter calorie control, while ribeye gets the nod when flavor and tenderness lead the list.
Practical Takeaways For Meal Planning
- For a 25–30 g hit: A cooked 3–4 oz ribeye portion covers it. That aligns with common meal targets many trainers use across breakfast, lunch, and dinner.
- For a bigger protein goal with fewer calories: Choose a leaner cut on some days. Protein per ounce stays close, but calories drop with less fat.
- For taste and texture: Ribeye shines. Keep portions measured and pair with fiber-rich sides.
How Many Times Should “Beef Ribeye Steak Protein” Appear?
You’ll see the phrase “beef ribeye steak protein” used naturally a few times here to match search language, yet the aim stays on clarity for readers. The goal is simple: precise numbers early, then useful context so a shopper can choose serving sizes that fit daily targets.
Daily Targets: Where Ribeye Fits
Food labels in the U.S. use a daily value of 50 g protein. That lets you map plate portions to a simple percentage. A cooked 4 oz ribeye at ~33 g protein lands near two-thirds of that figure in one go. See the FDA’s guide to the Daily Value for protein to translate portions into %DV on a label.
Cook Level And Rest Time
Doneness changes water loss. A steak pulled at medium-rare will weigh a bit more than one cooked well done. Resting on a rack helps hold juices in the meat rather than on the cutting board, which keeps the protein with the portion you serve.
Weighing: Raw Vs Cooked Portions
Recipe apps often ask for “raw weight” yet you eat “cooked weight.” If your plan targets 30 g protein at dinner, aiming for ~4 oz cooked ribeye gets you there. Buying and trimming to hit that target depends on yield. The USDA yield tables give typical loss ranges by cut and method, which helps you shop the right raw weight.
Label Terms That Affect The Numbers You See
- “Separable lean only”: The analysis removes external fat. Protein per 100 g looks higher than a test that includes fat caps.
- “All grades” vs “select/choice/prime”: Marbling varies by grade. Protein per ounce of the edible lean stays close; calories rise with more fat.
- Cooking method: Grilling, broiling, or pan-searing lead to similar protein density for the lean portion; the shift is mainly in moisture loss.
Applied Examples Using Real Portions
Target: ~30 Grams At One Meal
Plate 3–4 oz cooked ribeye. That serves ~25–33 g protein. Add a baked potato and salad for balance.
Target: ~50 Grams Across Two Meals
Split a larger steak. Eat ~3 oz cooked at lunch (~25 g) and another 3 oz at dinner. Protein stays steady across the day, which many lifters and dietitians prefer for satiety and recovery.
Target: ~100 Grams In A Day
That’s doable, yet it’s a big lift with ribeye alone because calories pile up with fat. Mix in leaner beef or poultry at other meals while keeping ribeye as a feature item.
Nerd Notes For Accuracy
The numbers here mirror published database entries, which carry lab methods, cut specs, and yield assumptions. Because steak sizes vary in the wild, your plate can drift a few grams either way. Trimming, grade, bone-in service, and doneness explain most swings you’ll see at the table.
Recap: What To Do With This Info
- Use the cooked table near the top to pick the portion that matches your protein goal.
- Remember that raw weight reads lower per ounce because of water.
- For label math, the protein daily value is 50 g; a 4 oz cooked ribeye gets you about two-thirds of that in one serving.
- Use “beef ribeye steak protein” as your search tag if you want to find this kind of chart again.
