Sirloin Steak with Chimichurri & Roasted Sweet Potatoes

High Protein & Easy recipe!

If you’re looking for a dinner that’s comforting, flavorful and packed with protein, this sirloin steak meal checks all the boxes. Lean sirloin delivers high‑quality protein, roasted sweet potatoes add natural carbs and fiber, and a fresh chimichurri sauce brings everything together with bright, herby flavor.

Why We Love This Meal

Sirloin is one of our favorite lean steak cuts. As a simple rule of thumb, any beef cut with “loin” in the name is typically leaner and a heart‑healthier option while still delivering great flavor. It’s naturally lower in fat than many steaks but still full of beefy flavor and incredibly versatile. An 8‑ounce cooked sirloin steak provides roughly 45–50 grams of protein, making it an excellent choice for anyone focused on building muscle, staying full longer, or simply adding more protein to their day.

Altogether, this dinner comes in around 55–60 grams of protein, making it a perfect high‑protein, balanced meal.
