Cooked beef chuck roast delivers about 7.7–9.5 grams of protein per ounce, depending on trim and cooking loss.
Want the real numbers from a chuck roast without guesswork? This guide shows protein per ounce from common chuck preparations and gives you simple conversions you can use while shopping or meal-prepping.
Beef Chuck Roast Protein Per Ounce By Cut
The protein you get from a chuck roast depends on two things: how much fat was trimmed and whether you’re reading raw or cooked data. “Lean only” cooked beef lands highest per ounce. “Lean and fat” lowers the number because more fat remains in each bite. Raw values show less protein per ounce because water loss during braising concentrates protein in the cooked meat.
| Preparation (USDA Description) | Protein Per Ounce | Notes |
|---|---|---|
| Arm pot roast, separable lean only, cooked, braised | 9.5 g | 28.4 g per 3 oz cooked; divide by 3 for per-ounce |
| Blade roast, lean & fat, cooked, braised | 7.7 g | 23.1 g per 3 oz cooked; divide by 3 for per-ounce |
| Arm pot roast, lean only, raw | 6.3 g | 22.1 g per 100 g raw; × 0.2835 for per-ounce |
These figures come from lab entries that list protein per 3-ounce cooked serving or per 100 g raw. To get “per ounce,” divide a cooked 3-ounce value by three, or multiply a 100 g raw value by 0.2835. Expect small swings across cuts and grades; the range above reflects real kitchen results.
Protein In Beef Chuck Roast Per Ounce: What Moves The Number
Trim Level
Cutting to “lean only” removes exterior and seam fat. Because fat displaces muscle, the same ounce carries more protein after a thorough trim. That’s why the lean-only braised arm roast sits near 9.5 g per ounce while the lean-and-fat blade roast averages around 7.7 g per ounce.
Raw Vs Cooked
Braising drives off water. Less water per ounce means a higher protein concentration. That’s the reason the raw lean-only value hovers near 6.3 g per ounce while the cooked lean-only value rises closer to 9.5 g per ounce.
Muscle Mix Inside The Chuck
Chuck spans several muscles. Some areas carry more connective tissue that softens into gelatin. Edible yield and moisture loss shift with that mix and with time on heat, nudging the final protein density a bit without changing the conversion method.
How To Convert Labels To Per Ounce
Most databases list protein “per 100 g” or “per 3 oz cooked.” Here’s the quick math you can use in the store or at the stove.
From 3 Ounces Cooked To Per Ounce
Divide by three. If a listing says 24 g protein per 3 oz cooked, that’s 8 g per ounce.
From 100 Grams Raw To Per Ounce
Multiply by 0.2835. If a raw chuck entry shows 22 g protein per 100 g, that’s about 6.2 g per ounce.
For primary entries, check MyFoodData’s chuck pot roast page (pulls from USDA lab data) and the USDA’s FoodData Central search.
Serving Guide For Protein Targets
Most eaters aim for 20–40 g protein per meal. Here’s what that looks like with cooked chuck.
Cooked Lean-Only Targets
- ~20 g: ~2.1 oz cooked (9.5 g × 2.1)
- ~30 g: ~3.2 oz cooked
- ~40 g: ~4.2 oz cooked
Cooked Lean-And-Fat Targets
- ~20 g: ~2.6 oz cooked (7.7 g × 2.6)
- ~30 g: ~3.9 oz cooked
- ~40 g: ~5.2 oz cooked
Planning by raw weight? Braising sheds water, so your cooked slices weigh less than the raw roast. Buy a little extra to hit the plate size you want.

| Cooked Ounces | Lean-Only (g) | Lean & Fat (g) |
|---|---|---|
| 1 oz | 9.5 | 7.7 |
| 2 oz | 19.0 | 15.4 |
| 3 oz | 28.4 | 23.1 |
| 4 oz | 37.9 | 30.8 |
| 6 oz | 56.8 | 46.2 |
| 8 oz | 75.7 | 61.6 |
Label Reading: Raw Vs Cooked Entries
Databases list both raw and cooked values. Use cooked values for cooked leftovers and sandwiches. Use raw values only when you’re logging raw weight going into a recipe and you’ll convert later using cooked yield. For a one-pan roast that turns into meal prep, it’s simplest to weigh the finished roast, then divide the total protein by the total cooked ounces to get your custom per-ounce number.
Minerals And B Vitamins Snapshot
Chuck isn’t just protein. A 3-ounce cooked portion of braised chuck typically brings heme iron, zinc, phosphorus, and B12 in meaningful amounts. Lab entries for braised chuck show zinc in the mid-to-high single-digits (mg) per 3 oz and iron in the 2–3 mg range. Pair your roast with a vitamin C source if you want to help iron absorption.
Buying And Trimming Tips
Pick The Right Piece
Look for a roast with visible grain and even marbling but without thick caps of hard fat. That balance helps tenderness without pushing protein per ounce down.
Trim Smart
Before braising, shave hard exterior fat and large seams. You don’t need to remove every speck. After cooking, chill the pot juices and lift the fat disk. You’ll keep flavor while moving your portion toward the “lean only” range.
Tame Sodium If You’re Brining
Store-bought broths and seasoning packets can spike sodium. If you’re tracking sodium, choose low-sodium broth and salt by taste after reducing the juices.
Beef Chuck Roast Protein Per Ounce In Real-World Cooking
The search phrase Beef Chuck Roast Protein Per Ounce usually means you want a fast, trustworthy range. Across USDA entries, cooked lean-only lands near 9–10 g per ounce and cooked lean-and-fat sits near 7–8 g per ounce. Raw values cluster near 6–7 g per ounce. The spread comes from trimming differences, muscle mix, and how much moisture you cook off.
Simple Portion Ideas (With Protein Math)
Taco Night
Two 2-ounce tacos built from lean-only chuck deliver ~38 g protein. Using lean-and-fat, the same tacos land near ~31 g.
Roast Bowl
Three ounces of lean-only chuck over rice and greens adds ~28 g protein. Double the meat if you’re chasing a higher target.
Sandwich
Four ounces of lean-and-fat chuck on a roll brings ~31 g protein. Swap in lean-only slices and you’ll be near ~38 g.
Storage And Leftover Smarts
Stash cooked slices in shallow containers so they cool fast. Reheat gently in the reserved juices to keep texture. The protein number per ounce won’t change with storage; only water loss from harsh reheating can nudge scale readings.
Common Mistakes That Skew Your Numbers
Counting Raw As Cooked
Raw 100 g entries don’t match cooked slices. If you’re logging a sandwich built from yesterday’s roast, use cooked values.
Mixing Trim Styles
Switching between “lean only” and “lean & fat” entries can swing protein by a couple grams per ounce. Pick one style and stick with it across a recipe series.
Weighing Drippy Pieces
Pat slices dry before weighing. A spoonful of broth on the board can steal a gram or two from your math.
Bottom Line For Meal Prep
Use 9.5 g per ounce for cooked, lean-only chuck and 7.7 g per ounce for cooked, lean-and-fat. When you only have raw data, multiply a per-100-gram value by 0.2835 to get a quick per-ounce estimate. With those two anchor numbers and one shortcut, you can plan portions fast and hit your protein target without guesswork.
