One 3-oz cooked sirloin tip steak provides about 25 g of protein; per 100 g cooked it averages 27–29 g, based on USDA beef nutrient data.
Looking up protein for a lean steak should be simple, but labels switch between raw and cooked weights and different cuts. This guide keeps it straight. You’ll see what a standard serving of sirloin tip delivers, how cooking changes the numbers, and how it stacks up against other common steaks.
Beef Sirloin Tip Steak Protein — What One Serving Gives You
Sirloin tip comes from the round “knuckle,” so it’s naturally lean. USDA lab tables show the lean-only, cooked version lands near the high end for protein per bite. In practical terms, a palm-size piece covers a big chunk of your daily target without a lot of fat.
| Serving | Protein (g) | Notes |
|---|---|---|
| 100 g cooked, lean only | 29 | Choice grade, roasted; 27 g if select |
| 85 g cooked (≈ 3 oz), lean only | 25 | Matches USDA 85 g column |
| 4 oz cooked (≈ 113 g) | ~32 | Calculated from 28–29 g per 100 g |
| 6 oz cooked | ~48 | Macro-friendly entree portion |
| 8 oz cooked | ~64 | Big steak night portion |
| 100 g raw, lean only | 21 | Raw values run lower due to water |
| 4 oz raw (≈ 113 g) | ~24 | Weigh before cooking for accuracy |
| One 8-oz raw steak → ~6 oz cooked | ~48 | Typical yield after moisture loss |
Why The Numbers Shift Between Raw And Cooked
Cooking drives off water. The steak gets lighter, so the protein looks more concentrated “per 100 g.” Your total protein doesn’t vanish; the weight you compare against changes. This is why USDA tables list separate rows for raw and cooked cuts.
Quick Math You Can Use At The Stove
Most lean beef sits near 7–8 g protein per cooked ounce. For sirloin tip, use 8 g per cooked ounce as a handy rule. A 6-oz cooked steak? Plan on ~48 g. If you weigh raw portions, expect about one-quarter shrinkage when it hits the pan.
Protein In Sirloin Tip Steak By Cooking Method
Grilling, roasting, or pan-searing won’t change the protein in the meat itself. What changes is the yield. A quick sear with a moderate finish usually holds more moisture than a long roast, but the difference is small at home. The lean-only, cooked values in the USDA tables reflect trimmed steak after cooking to a safe internal temperature.
Best Ways To Hit Your Target
- Weigh consistently. Pick raw or cooked weighing and stick to it in your tracker.
- Trim visible fat. Sirloin tip is already lean, so the protein-to-calorie ratio stays strong.
- Slice across the grain. Shorter fibers make a lean cut feel tender without sauces.
- Use a thermometer. Cook to your preferred doneness, rest, then slice.
How This Fits Daily Protein Needs
The Dietary Reference Intake for adults is 0.8 g of protein per kilogram of body weight. Many active adults aim higher. A single 6-oz cooked sirloin tip puts ~48 g on your plate, which can meet half or more of a typical day’s target in one meal. For source details, see the National Academies’ chapter on protein needs (Dietary Reference Intakes) and the USDA’s cut-by-cut nutrient tables (USDA beef nutrient tables).
Beef Sirloin Tip Steak Protein Compared To Other Cuts
How strong is sirloin tip next to other steaks? Per 100 g cooked (lean only), it sits right with top sirloin, flank, and tenderloin. Here’s a side-by-side snapshot so you can choose by flavor or fat while keeping grams steady.
| Cut (Cooked, Lean Only) | Protein (g) / 100 g | Total Fat (g) / 100 g |
|---|---|---|
| Sirloin Tip (Tip Round, Roasted) | 29 | 5 |
| Top Sirloin Steak, Broiled | 30 | 7 |
| Flank Steak, Broiled | 28 | 8 |
| Tenderloin (Filet), Broiled | 28–29 | 9 |
| Bottom Round Steak, Grilled | 27 | 7 |
Takeaways From The Comparison
- Protein stays clustered. Lean steaks vary by 2–3 g per 100 g cooked.
- Fat is the swing factor. Tenderloin and top sirloin carry a bit more fat than sirloin tip and bottom round.
- Portion wins. Choose the cut you like, then size the plate to hit your gram goal.
How Much Steak To Reach Common Goals
Use these examples to plan meals around your target. Round to the nearest ounce in real life; the point is to get close and be consistent from day to day.
Goal: ~30 g Protein At Lunch
Cook 4 oz of sirloin tip (about 113 g cooked). Add roasted potatoes and a green salad. You’ll land near 32 g protein with a balanced plate.
Goal: ~45–50 g Protein At Dinner
Cook 6 oz of sirloin tip. Add a cup of beans or lentils and charred vegetables. You’ll sit near 48 g from the steak plus another 7–9 g from the sides.
Goal: ~90 g Protein For The Day
Build three 30 g “anchors.” Breakfast: Greek yogurt and fruit. Lunch: 4 oz cooked sirloin tip in a grain bowl. Dinner: Eggs with toast and a cup of milk. Simple, steady, and easy to repeat.
Buying And Prepping Tips For Tender Results
Choose The Right Piece
Look for “sirloin tip,” “knuckle,” or “tip steak.” Thicker cuts sear better and slice cleanly. A uniform 1 to 1¼-inch thickness gives you a broad edge-to-edge pink center.
Marinate For Moisture
A short soak (30–90 minutes) in a mix with salt and acid helps. Think soy, garlic, and a splash of citrus or vinegar. Pat dry before it hits a hot pan.
Sear, Then Finish Gently
Get color first. Then drop the heat or move to a moderate oven to finish. Rest at least five minutes before slicing.
Slice Across The Grain
Sirloin tip has long fibers. Thin, cross-grain slices chew better and taste juicier, which matters when you’re working with a lean steak. Keep slices thin for tenderness.
Label Clarity: Raw Vs. Cooked Weights
Grocery labels often list raw weight. Restaurant menus usually list cooked weight. If your plan calls for 30 g protein from steak, either weigh it cooked and use the cooked column, or weigh the raw piece and use the raw numbers. Mixing methods makes logs messy.
Macros And Micronutrients You Get With The Protein
Beyond protein, sirloin tip brings iron, zinc, and B vitamins. Lean-only, cooked sirloin tip sits around 5 g fat per 100 g, which keeps calories in check next to richer cuts. Pair with fiber-rich sides and you’ve got an easy, steady meal pattern.
Smart Swaps That Keep Protein High
- Need lower fat? Choose bottom round or sirloin tip and trim after cooking.
- Want more tenderness? Go with tenderloin, but watch the extra fat per 100 g.
- Crave beefy flavor? Top sirloin or flank brings it, with protein right in the same band.
How To Log It Cleanly In A Tracker
Pick one entry that matches “sirloin tip” or “tip round” with “lean only, cooked” in the description. Cross-check the per 100 g values with USDA to avoid crowd-sourced errors. If you prefer to log by ounces, set a custom food at 8 g protein per cooked ounce and you’re set.
Cost And Shopping Notes
Sirloin tip usually prices below tenderloin and top sirloin while staying lean. Buy larger roasts when they’re on sale, then slice into steaks at home. Freeze portions flat in zip bags. They thaw quickly in cold water and cook evenly.
Meal Ideas That Hit The Numbers
Stir-Fry Bowl
Slice thin strips of sirloin tip, then flash-cook with peppers, onions, and a light soy-ginger sauce. Serve over rice or quinoa. The protein stays high and the cooking time stays short.
Grain Salad With Steak
Toss cooked farro with arugula, cherry tomatoes, and a lemon-olive oil dressing. Add warm slices of sirloin tip on top. The mix brings carbs, greens, and a clean 30–40 g of protein depending on portion size.
Common Pitfalls (And Simple Fixes)
- Using crowd-sourced entries. Match to USDA values before logging.
- Guessing on yield. If your steak looks small after cooking, it is. Weigh cooked portions until your eye gets trained.
- Overcooking. Dry steak feels tougher, which makes slices seem smaller. Pull earlier and rest.
Leftovers That Work For You
Cook once, eat twice. Chill cooked slices on a sheet pan, then move to containers. They’ll keep texture for salads, tacos, or a quick egg scramble. A 3-oz portion packs about 25 g protein, so two small handfuls can turn a simple bowl into a complete meal.
Micronutrient Perks At A Glance
Lean beef brings heme iron, zinc, and B vitamins that help with energy metabolism and immune function. Sirloin tip sits in a sweet spot: strong protein per ounce with moderate fat. Pair with greens for iron absorption and you get more from the same ounces of steak.
Bottom Line
Beef sirloin tip steak protein is easy to plan when you use cooked, lean-only numbers. A 3-oz cooked serving gives about 25 g; a 6-oz cooked steak gives about 48 g. That keeps meal planning simple without giving up flavor.
When you need a lean, budget-friendly cut that still brings strong numbers, sirloin tip checks the box. If your tracker ever confuses you, search for the USDA entry and move on. steak night solved, grams locked.
