One cooked 3-oz bottom round steak delivers about 23 g of protein; 100 g cooked lands near 27 g based on lab-tested beef data.
Beef bottom round comes from the outside of the rear leg. It’s a lean, budget-friendly cut that shines when sliced thin across the grain. If your goal is steady protein with fewer calories from fat, this steak hits a sweet spot. Below you’ll find clear numbers for beef bottom round steak protein across common serving sizes, how cooking changes the count, and simple ways to reach a daily target without guesswork.
Beef Bottom Round Steak Protein: What Counts As A Serving
Most nutrition panels for steak use either 3 ounces cooked (about 85 g) or 100 g cooked as a reference serving. For bottom round, lab datasets report about 23 g protein per 3 oz cooked and about 27 g per 100 g cooked. Raw values run lower per 100 g because water loss during cooking concentrates the nutrients. The figures below come from beef cut testing published by the USDA and hospital nutrition libraries that source those datasets.
First Look At The Numbers
Here’s a quick table you can scan before planning meals. Values are averages; trimming level and doneness move the final gram or two either way.
| Serving | Protein (g) | Calories |
|---|---|---|
| 3 oz cooked, grilled/braised | ≈23 | ≈160 |
| 100 g cooked | ≈27 | ≈191 |
| 100 g raw | ≈21 | ≈150 |
| 4 oz cooked | ≈31 | ≈215 |
| 6 oz cooked | ≈46 | ≈320 |
| 8 oz cooked | ≈62 | ≈430 |
| 1 steak raw (varies by cut size) | ≈66 per 300 g raw yield | ≈430 |
Where do these figures come from? Bottom round steak has detailed nutrient profiles in the USDA retail beef cuts data, which shows about 27 g protein per 100 g cooked for the outside round/bottom round steak. A hospital nutrition library that mirrors the same dataset lists about 23 g protein for a 3-oz cooked serving of bottom round steak. Those two anchors make planning straightforward.
Protein In Bottom Round Steak By Size And Cooking Method
Bottom round is lean to begin with, and trimming makes it leaner. Cooking method affects yield and moisture. Braising or grilling drives off water, which bumps protein per 100 g because the steak weighs less after cooking. Per portion, the 3-oz cooked serving sits near 23 g protein across doneness levels. If you weigh cooked portions, the per-100-gram figure (≈27 g) is your best guide.
Raw Vs. Cooked: Why The Numbers Shift
On a raw label you might spot about 21 g protein per 100 g. After cooking, the same steak loses water and fat, so every cooked 100 g now packs more protein by weight. That’s why the cooked table shows ≈27 g per 100 g. Neither value is “better”—they just reflect different reference weights. For meal logging, pick one method and stick with it so your totals stay consistent.
Lean-Only Trimming
If the steak is trimmed tight and you slice off surface fat after cooking, calories fall a bit while protein stays about the same per cooked ounce. Since bottom round doesn’t carry heavy marbling, the swing is modest compared with richer cuts.
How Beef Bottom Round Steak Protein Fits Daily Targets
Daily protein needs vary with body size and training status. Many readers aim for 1.2–2.0 g per kg body weight. In meal terms, think in sets of 20–40 g through the day. Using the 3-oz cooked anchor at ~23 g, you can build plates without math headaches.
Quick Portions That Hit Common Targets
- 20–25 g: about 3–3.5 oz cooked bottom round.
- 30–35 g: about 4–5 oz cooked.
- 40–45 g: about 5.5–6.5 oz cooked.
Protein Density And Calories
Bottom round keeps calories reasonable for the protein you get. A 4-oz cooked portion sits near 31 g protein and roughly 215 calories. That density helps on cut phases or any plan that prioritizes protein per calorie.
Nutrition Extras You Get With Bottom Round
Protein is the headline, but this cut brings iron, zinc, and B vitamins. Iron lands around 2.5 mg per 3-oz cooked serving, while zinc sits a bit above 4 mg in the same portion. Those minerals support oxygen transport and normal immune function. If you track micronutrients closely, bottom round can cover a good share of those daily boxes without pushing fat too high.
Cut Facts In Context
Compared with ribeye or T-bone, bottom round trades some tenderness for leanness. That’s a good swap when your priority is protein with fewer calories. A sharp knife and thin slices across the grain go a long way for tenderness, especially after a rest under foil.
Smart Cooking To Keep Protein High
Protein won’t disappear in the pan, but technique can change the experience—and your portion weight. These simple steps protect yield and texture.
Marinate For Surface Tenderness
A short marinade with salt, garlic, and a splash of acid helps the outer layer stay juicy. Pat dry before searing so the surface browns instead of steaming.
Sear, Then Finish Gently
Give the steak a hot sear for color, then finish at a lower heat or in a low oven. Pull at medium-rare to medium and rest 5–10 minutes to keep juices in the meat, not on the board.
Slice Thin Across The Grain
Bottom round has long muscle fibers. Cutting across those fibers in thin slices makes each bite tender without changing the nutrition.
Building A Plate Around Beef Bottom Round Steak Protein
Pick a protein target first, then back-fill with sides that match your plan. If you want a 30 g protein plate from bottom round, 4 oz cooked gets you close. Add roasted vegetables and a simple starch for energy, or keep it light with a salad if calories are tight.
Sample Plates
- High-Protein, Moderate Calories: 5 oz cooked bottom round (≈38 g protein), roasted broccoli, baked potato, olive-oil drizzle.
- Lower-Calorie, Protein-Forward: 4 oz cooked bottom round (≈31 g protein), big salad, lemon vinaigrette, grilled asparagus.
- Sandwich Prep: Thin-sliced bottom round on whole-grain roll, mustard, arugula; weigh 4–5 oz cooked slices to lock in 30–35 g protein.
How To Log It Correctly
Tracking apps often mix raw and cooked entries. To keep your diary honest, log the same way every time. If you weigh cooked meat on the plate, use cooked references: ≈23 g per 3 oz cooked or ≈27 g per 100 g cooked. If you prep a batch and portion raw weights into bags, use raw references: ≈21 g per 100 g raw, then note your typical cooked yield for next time.
Why Some Apps Show Different Protein
User-entered items can drift. When accuracy matters, favor entries that cite lab datasets. Two reliable anchors you can use mid-scroll are the USDA retail beef cuts PDF (detailed per-100-g data) and a cooked bottom round page with per-serving breakdowns on a dataset-driven site. Linking to them here makes verification easy.

Frequently Asked Practical Questions
How Many Ounces Do I Need For 30 Grams Of Protein?
About 4 oz cooked bottom round gets you to 30–31 g. If you prefer 25 g, 3–3.5 oz cooked is the range.
Does Doneness Affect Protein?
Protein grams in the steak stay the same; the weight changes with moisture loss. That’s why per-100-g cooked values look higher than raw. Use cooked references if you weigh cooked food.
What About Amino Acids?
Bottom round has a complete amino acid profile, like other beef cuts. You get all the essential amino acids in ratios that support muscle protein synthesis when your daily total is on target.

| Daily baseline idea | 90 | ≈12 oz cooked across meals |
Bottom Round Buying And Prep Tips
Choose The Right Piece
Look for even thickness and a smooth grain. A bit of exterior fat is fine; you can trim after cooking. Since the muscle is worked, tenderness comes from thin slicing, not heavy marbling.
Batch Cook For The Week
Roast or braise a larger piece, chill, and slice thin for sandwiches, bowls, or quick stir-fries. Weigh portions after cooking if you plan to use cooked references in your tracker.
Flavor Without Extra Calories
Use salt, pepper, garlic, and herbs, then finish with lemon or vinegar. A simple pan sauce from stock and mustard adds punch with minimal fat.
Key Takeaways You Can Act On Today
- Use clear anchors: ≈23 g per 3 oz cooked; ≈27 g per 100 g cooked; ≈21 g per 100 g raw.
- Weigh the way you log: cooked weight with cooked references, or raw weight with raw references.
- Plan in sets: 3–3.5 oz cooked for ~20–25 g; 4–5 oz cooked for ~30–35 g; 6 oz cooked for ~45 g.
- Slice across the grain: better bite, same protein.
Use these numbers to guide your next grocery run and prep session. With beef bottom round steak protein as your base, you can build meals that hit targets cleanly, stay on budget, and taste great.
