Flank Steak: A Powerhouse of Protein
Flank steak, a cut from the cow's abdominal muscles, is a versatile and flavorful option that has become a staple for health-conscious consumers. Unlike some other steak cuts, it is relatively lean and offers an impressive amount of high-quality protein, which is crucial for muscle repair, growth, and overall bodily function. Its distinct grain and robust flavor profile make it a popular choice for dishes like fajitas and stir-fries, but its nutritional value is what truly sets it apart for those with active lifestyles. With virtually no carbohydrates, it fits well into low-carb and ketogenic dietary plans as well.

Tips for Cooking High-Protein Flank Steak
Given that flank steak is a lean cut, proper cooking technique is essential to prevent it from becoming tough. The right preparation will not only ensure a tender and juicy meal but also preserve its nutritional integrity.
- Marinate for Tenderness: Marinating flank steak is the most effective way to tenderize it before cooking. Use an acidic marinade with ingredients like vinegar or citrus juice, as this helps break down the muscle fibers.
- Cook Over High Heat: Use a grill, cast iron skillet, or broiler for a quick, high-heat cook. This method creates a flavorful crust while keeping the inside moist and tender. Cook to medium-rare for best results.
- Slice Against the Grain: This is perhaps the most important step for tender flank steak. After cooking and resting, identify the direction of the muscle fibers (the grain) and slice thinly, at a 45-degree angle, perpendicular to the grain.
- Rest the Meat: Always let the steak rest for 5-10 minutes after cooking. This allows the juices to redistribute throughout the meat, ensuring every slice is as juicy as possible.
For a delicious and healthy recipe, consider a grilled flank steak with a balsamic and herb marinade. You can find excellent recipe ideas to get started here.
