How Much Protein Is in Beef, by Cut

Beef is a popular source of high-quality protein, essential for muscle repair, immune function, and keeping you feeling full. The amount of protein in beef varies by cut, largely due to differences in fat and connective tissue. Below, we break down the protein content of common beef cuts based on data from the U.S. Department of Agriculture (USDA) and other credible nutrition databases.

Why Protein in Beef Matters

• Protein supports muscle growth and repair.
• It helps regulate appetite by promoting satiety.
• Essential amino acids in beef are critical for immune health, hormone production, and energy metabolism.
• Leaner cuts deliver more protein per calorie, while fattier cuts offer more energy (from fat) but slightly less protein by weight.

Factors That Affect Protein Content

1. Cut-to-Cut Variation
   • Lean cuts (e.g., top round, sirloin) are higher in protein per ounce than marbled cuts (e.g., ribeye).
2. Fat Percentage
   • More intramuscular fat lowers the relative protein percentage.
3. Cooking Method & Loss
   • Grilling or broiling beef causes moisture and fat loss, concentrating protein.
   • Boiling or stewing retains moisture; protein values may be slightly lower per cooked ounce.

Protein Content by Cut (Cooked, 3-Ounce Portions)

Below are approximate protein values in cooked 3-ounce portions, unless noted otherwise. Variations of ±1–2 grams can occur depending on specific trim and cooking techniques.

Steak Cuts

• Top Sirloin (lean)
  Protein: ~25 g
  Calories: ~160
• Tenderloin / Filet Mignon
  Protein: ~24 g
  Calories: ~175
• Ribeye (more marbling)
  Protein: ~23 g
  Calories: ~210
• New York Strip
  Protein: ~24 g
  Calories: ~180
• T-Bone / Porterhouse
  Protein: ~23 g
  Calories: ~200

Roast & Round Cuts

• Top Round Roast (lean)
  Protein: ~26 g
  Calories: ~155
• Bottom Round Roast
  Protein: ~26 g
  Calories: ~150
• Eye of Round Roast

  Calories: ~230
• 85% Lean / 15% Fat
  Protein: ~23 g
  Calories: ~215
• 90% Lean / 10% Fat

  Calories: ~200
• 95% Lean / 5% Fat
  Protein: ~25 g
  Calories: ~170

Comparing Lean and Marbled Cuts

• Leaner cuts (round, sirloin) deliver roughly 25–27 g of protein per 3 oz cooked, with 140–160 calories.
• Marbled cuts (ribeye, brisket) range from 22–23 g of protein per 3 oz cooked, but provide 200+ calories from higher fat content.

Practical Tips for Maximizing Protein Intake

• Choose lean cuts if your goal is to boost protein without extra calories.
• Trim visible fat before cooking.
• Use cooking methods that minimize added fats (grilling, broiling, roasting).
• Weigh raw meat to ensure consistent portion sizes; 3 oz cooked starts as about 4 oz raw.
• Pair beef with vegetables and whole grains to round out your meal.

Sample Meal Planning

• Breakfast: Beef and veggie scramble with 3 oz cooked lean ground beef (~24 g protein).
• Lunch: Top sirloin salad (3 oz grilled sirloin, mixed greens; ~25 g protein).
• Dinner: Flank steak fajitas (3 oz cooked flank steak; ~23 g protein) plus beans and salsa.

Total daily protein from these beef servings exceeds 70 g, meeting or surpassing the Recommended Dietary Allowance (RDA) for most adults.
