One cooked 100 g portion of beef liver packs about 30 g of protein; raw 100 g sits near 20 g, and a typical 85 g cooked slice lands around 25 g.
Beef liver is a compact source of complete protein that also brings B-vitamins, iron, and choline. This guide gives clear numbers you can use at the stove and at the table, so you can plan portions with confidence.
Beef Liver Protein Content: Serving Sizes And Math
Cooked weight tells the real story. During cooking, water cooks off and the protein share per 100 grams rises. That is why braised or pan-fried portions show a higher protein number than raw weight for the same piece.
Here is a compact table near the top, so you can size a meal fast. Values come from standard entries built on USDA FoodData Central data and clean roll-ups from MyFoodData.
| Portion | State | Protein (g) |
|---|---|---|
| 100 g | Cooked (braised) | ~29.6 |
| 100 g | Raw | ~20.4 |
| 85 g | Cooked slice | ~25 |
| 3 oz (85 g) | Cooked | ~25 |
| 1 oz (28 g) | Cooked | ~5.5 |
| 200 kcal portion | Cooked | ~59 |
| 1 cup chopped (cooked, est.) | Cooked | ~35–40 |
Why The Numbers Differ By Cooking
Raw liver holds more water. With heat, moisture drops and the protein share rises. That change boosts protein per 100 grams of cooked weight. The raw and cooked columns here refer to the state at the moment you weigh the food.
For tracking, keep one unit consistent. If you weigh food on the plate, use cooked values. If you plan a grocery list, raw numbers help, then switch to cooked when you track the meal itself.
Beef Liver Protein Per 100 Grams And Per Slice
Use two anchor points. A cooked 100 gram portion averages near 29–30 grams of protein. A raw 100 gram portion sits near 20 grams. One cooked slice at 85 grams lands close to 25 grams. Those three points cover most plates at home.
In the middle of a weeknight rush, a palm-sized slice is roughly 80–90 grams once cooked. That means you can hit a 20–26 gram target with one slice and round out the plate with greens and starch.
Inside the article body we also repeat the exact phrase beef liver protein content so searchers who use that wording can match this page quickly. You will see it again in a moment in a section that compares cuts and pantry items.
How It Stacks Up Against Common Proteins
Liver is lean and dense, though a plain chicken breast still leads by protein per 100 grams. The next table puts cooked values side by side so you can see trade-offs at a glance. Values draw from the same USDA stream via MyFoodData for a fair match-up.
| Food | Typical Prep | Protein (g) |
|---|---|---|
| Beef liver | Braised | ~29.6 |
| Chicken breast | Roasted | ~31 |
| Top sirloin steak | Broiled | ~27–29 |
| Egg (hard-boiled) | Peeled | ~12–13 |
| Salmon | Baked | ~25 |
Portion Targets, Leucine Trigger, And Meal Ideas
Most lifters aim for 25–35 grams of protein per meal. A single cooked slice of liver drops right into that window. Pair it with eggs at breakfast, or with potatoes and a salad at dinner. If you need 40 grams, add a small cup of Greek yogurt or an extra egg on the side.
Hitting the leucine trigger supports muscle protein building during a meal. Liver supplies branched-chain amino acids along with methionine and lysine. A plate that includes liver plus dairy or eggs easily clears common leucine targets set in strength circles.
If you track macros, keep an eye on cholesterol and vitamin A. Liver brings sky-high retinol. Adults have upper limits for preformed vitamin A set by the NIH Office of Dietary Supplements. Read the table there, then line up your meals and any pills you take.
Cooking Tips That Keep Texture And Protein
Quick browning keeps the bite tender. Slice across the grain, blot, season with salt and pepper, and cook in a hot pan for a short spell. Overcooking dries the slice and can turn the taste sharp.
A short milk soak can soften flavor for new eaters, but it is not a must. Trim membranes and any large vessels so the slice cooks evenly. A light dredge in flour can help sear, though slices work fine.
Skip heavy breading if you need a tight macro plan. The breading adds carbs and lowers the protein per 100 grams of the finished plate. Season with onions, thyme, and a splash of stock for a fast pan sauce that does not dent the numbers.
Protein Plus Standout Micronutrients
Beyond protein, beef liver brings heme iron, B12, riboflavin, folate, and choline in striking amounts. That mix supports red blood cell formation and many enzyme systems. A small serving goes a long way on the vitamin and mineral side.
That said, retinol is sky-high. Many eaters do well with a once-a-week slice. If you use a multivitamin or cod liver oil, read labels and tally retinol so you do not overshoot the daily cap. The NIH page linked above lists the numbers in plain units for quick checks.
Buying, Trimming, And Safe Storage
Shop for firm, glossy pieces with deep color and clean scent. Keep liver cold from store to home. In the fridge, wrap tightly and use within two days. For longer holds, freeze portions flat. Thaw in the fridge, not on the counter.
Before cooking, trim away sinew and any green spots near the gall area. Slice to even thickness so the pan work is predictable. Pat dry so the surface sears, not steam.
Tracking, Raw Vs Cooked Entries, And Swaps
When you log a meal, match the entry to the food on the plate. If the slice is cooked, pick the cooked entry. If your app only shows raw entries, enter the raw weight before cooking, not the cooked plate weight. That keeps the math clean.
If you need a swap, chicken breast gives the most protein per 100 grams among common meats. Sirloin runs close behind. For a meatless night, firm tofu and Greek yogurt can stand in while you still hit a protein target.
This section repeats the exact lowercase phrase beef liver protein content in body text to match searchers who type that string. The page stays natural while meeting the query head-on.
Data Sources And How To Read Labels
The cooked and raw figures here align with entries pulled from Beef Liver, Braised and a raw entry that lists 20.4 g protein per 100 g. For chicken breast, a typical cooked entry shows about 31–32 g per 100 g. Hard-boiled eggs sit near 12–13 g per 100 g. Those links roll up USDA lab data in a readable format.
Package labels can vary by brand and water content. If a label lists a very different number, check the serving size and the state of the food. A drained weight or a packed-in-liquid item will shift the math on the panel.
Protein Quality, Digestibility, And Satiety
Liver protein ranks high on quality scales used in nutrition labs. It delivers all nine essential amino acids in strong amounts and digests well. Many eaters notice steady fullness from a plate that pairs liver with fiber-rich sides. That mix can help with appetite control during a busy week.
Simple Plates That Hit A Protein Target
Try thin slices with onions and a baked potato. Add a bowl of leafy greens to round out the plate. Or pan-sear strips and fold them into warm tortillas with salsa and shredded cabbage. Another fast move: pair liver with soft-scrambled eggs and toast too.
Batch cooking works well. Sear several slices at once, cool, and store in a covered dish. Reheat gently in a skillet with a splash of stock. The texture stays tender and the protein math does not sway.
Common Pitfalls And Easy Fixes
Bitterness often comes from overcooking. Pull the slices off the heat while the center stays just pink, then rest them. A quick pan sauce knocks back any sharp note. If the flavor feels bold, serve smaller pieces with plenty of onions and herbs.
Handy Math You Can Use Without A Scale
No scale on hand? A palm-size cooked slice is about 80–90 grams and carries roughly 24–27 grams of protein. Two small strips that fill a taco shell add up to 50–60 grams and bring 15–18 grams. A heaping half cup of chopped cooked liver lands near 70 grams and yields about 20 grams.
These cues keep you close to target on travel days or at a friend’s house. When you get back to your kitchen scale, verify a plate or two and tune your eye.
When To Pick Another Protein
Some folks prefer to cap liver intake due to vitamin A. If you eat liver sometimes and use a multivitamin that already carries retinol, pick a different main dish on the next day. Chicken breast or turkey breast suits a high protein plan with mild taste. Tofu or Greek yogurt sets up smooth, dairy-lean plates when meat is off the menu.
Pregnant people and those on retinoid drugs need tailored advice from a clinician. The linked NIH sheet lists the upper limits for retinol so you can raise that topic at your next visit.
