How Much Protein Is in 8 oz of Steak?

Ever wondered how much protein is actually in that juicy steak on your plate?
Let me break it down for you – because I know you’re not counting grams of protein when you’re at Texas Roadhouse with your family.
Most 8-ounce steaks pack 50-70 grams of protein depending on the cut. That’s about the same amount as 8-10 eggs or two chicken breasts.
But not all steaks are created equal, and knowing which cuts give you the most nutritional bang for your buck might help next time you’re ordering.
The Protein Content of Different Steak Cuts
Let’s get right into the meat of the matter (see what I did there?).
Here’s how different steak cuts stack up in protein content when you’ve got an 8-ounce cooked portion:
- Top Round: ~58 grams protein, ~10g fat, ~320 calories
- Flank Steak: ~56 grams protein, ~11g fat, ~300 calories
- Sirloin: ~54 grams protein, ~15g fat, ~320 calories
- Filet Mignon: ~56-60 grams protein, ~13g fat, ~300 calories
- Strip Steak: ~50-52 grams protein, ~15g fat, ~320 calories
- Ribeye: ~42-50 grams protein, ~22g fat, ~375 calories
- T-Bone: ~50 grams protein, ~19g fat, ~350 calories
Why Do Some Steaks Have More Protein Than Others?

You might be wondering why there’s such a difference between cuts. It’s pretty simple, actually.
Leaner cuts = more protein per ounce. That’s because they have more muscle tissue and less fat.
Think about it like this: every bit of marbling (those white streaks of fat that make ribeyes so delicious) is taking up space that could otherwise be filled with protein-rich muscle.
That’s why a top round steak has more protein than a ribeye – it’s got less of that delicious fat running through it.
Also, how you cook your steak matters. When you grill or broil your steak, you keep more of the natural protein intact versus, say, deep frying it.
Steak’s Nutritional Superpowers (Beyond Just Protein)
Steak isn’t just about the protein. It’s like the multivitamin of the meat world.
Each serving delivers:
- Iron: Critical for carrying oxygen in your blood
- Zinc: Supports your immune system and helps with wound healing
- B vitamins: Especially B12, which many people are deficient in
- Creatine: Helps with muscle energy and performance
Fun fact: Your body absorbs iron from animal sources (called heme iron) way better than iron from plants. So if you’ve been feeling tired lately, maybe your body’s craving a steak for a reason.
How Much Protein Do You Actually Need?

So now you know an 8-oz steak has about 50-70g of protein. But is that too much? Not enough? Just right?
The official recommendation is about 0.8 grams of protein per kilogram of body weight for most adults. For a 175-pound person, that’s roughly 63 grams of protein daily.
But that’s the minimum to avoid deficiency, not necessarily optimal.
If you’re active or trying to build muscle, research suggests you might benefit from 1.2-2.0 grams per kilogram. That’s up to 175 grams of protein daily for our 175-pound example person.
So one 8-oz steak could supply anywhere from 30% to 100% of your daily protein needs, depending on your size and activity level.
Making Smart Steak Choices

If you’re watching your calories but still want your protein fix, go for leaner cuts like top round, sirloin, or flank steak.
If you’re going keto or low-carb and need more fat with your protein, ribeye and T-bone are your friends.
And if you’re splurging on a fancy dinner out, a filet mignon gives you tons of protein with moderate fat and melt-in-your-mouth tenderness.
Grass-fed beef might also offer some additional nutritional perks like more omega-3s and antioxidants compared to conventional beef.
The Bottom Line on Steak and Protein

An 8-ounce steak delivers a serious protein punch of 50-70 grams, plus important micronutrients your body needs.
Leaner cuts like top round and sirloin give you more protein per calorie, while fattier cuts like ribeye offer more flavor but less protein density.
For best results, try balancing your plate with some veggies and perhaps a small portion of complex carbs for a complete meal.
And if you’re like me, maybe don’t tell your partner about the full fat content in that ribeye. Some information is better kept to ourselves.
