Calculating the Protein in 350 Grams of Rump Steak
When assessing the protein content of meat, it's crucial to understand the difference between raw and cooked weights. Lean, raw rump steak contains, on average, about 21-22 grams of protein per 100 grams. Using this figure, a 350-gram raw portion would provide approximately 73.5 to 77 grams of protein before cooking. During the cooking process, meat loses a significant amount of water, typically around 25% of its raw weight, but the total protein content remains virtually unchanged. This means your cooked steak will weigh less but have a more concentrated protein-to-weight ratio. For example, if a 350g raw steak loses 25% of its weight, it will weigh about 262.5g cooked, while still containing the original 73.5 grams of protein. This is a key detail for anyone tracking their macronutrient intake based on cooked food portions. The excellent bioavailability of the protein in beef, rated around 94%, ensures your body can efficiently absorb and utilize these essential amino acids.
Raw vs. Cooked: How to Accurately Measure Your Intake
Many people make the mistake of weighing their meat after it has been cooked. For the most accurate and consistent tracking, it is best practice to measure the raw weight of your ingredients. This accounts for the natural water loss during cooking and prevents you from underestimating your protein intake. For those weighing cooked portions, you would need to adjust your calculations or rely on nutritional information that specifies the cooked weight. The difference is significant and can impact your progress towards fitness goals, especially if you are aiming for high protein targets.
Rump Steak's Complete Nutritional Profile
Beyond its impressive protein content, rump steak is packed with a range of other essential nutrients, making it a valuable addition to a balanced diet. As a complete protein source, it contains all nine essential amino acids that the body cannot produce on its own. It is also a rich source of highly bioavailable haem iron, which is absorbed much more effectively by the body than the non-haem iron found in plant sources.
Other notable nutrients include:
- Zinc: Essential for a healthy immune system, wound healing, and cell growth.
- Vitamin B12: Crucial for nervous system function and the formation of red blood cells, and found almost exclusively in animal products.
- Selenium: An antioxidant that helps protect cells from damage.
- B Vitamins: A good source of B vitamins like niacin and B6, which support energy metabolism.

| Rib Eye | ~241 | ~17 | ~19 | Very high fat content; rich flavour |
Best Cooking Methods for Rump Steak
To ensure your rump steak is tender and juicy, careful cooking is required due to its leaner nature. Overcooking can make it tough and dry, and while nutrient loss is minimal with proper technique, the texture can be greatly impacted.
Tips for perfect cooking:
- Bring to room temperature: Let the steak sit out for 30 minutes before cooking for more even results.
- Season generously: Use coarse salt and freshly ground pepper right before cooking.
- Use high heat: Sear the steak in a hot, heavy-bottomed pan or on a grill for 3-4 minutes per side for medium-rare. A hot surface creates a flavourful crust and helps lock in juices.
- Rest the meat: This is a crucial step. After cooking, let the steak rest for 5 to 10 minutes to allow the juices to redistribute.
- Slice against the grain: To ensure maximum tenderness, always slice the steak against the direction of the muscle fibres.
