Understanding Flank Steak

What is Flank Steak?

Flank steak is a flat cut of beef that comes from the abdominal muscles of the cow. Known for its rich, beefy flavor, flank steak is very lean, making it a healthier option compared to some of the fattier cuts. While it is flavorful, its leanness can also make it tough if not cooked and sliced properly.

Why Choose Flank Steak?

1. Flavorful: Flank steak has a robust beef flavor that can be enhanced with marinades and seasonings.
2. Versatile: This cut works well in a variety of dishes, from tacos to salads.
3. Cost-Effective: Flank steak is relatively affordable compared to other beef cuts, making it a great choice for families and meal prepping.
4. Quick Cooking: Because it’s thin, flank steak cooks quickly, making it perfect for weeknight dinners.

Nutritional Benefits

Flank steak is an excellent source of protein, essential vitamins, and minerals. It is low in carbohydrates and high in iron, making it a great option for those looking to maintain a balanced diet.

Preparing Flank Steak

Choosing the Right Flank Steak

When shopping for flank steak, look for a cut that is evenly thick throughout. A uniform thickness ensures even cooking, which is crucial for achieving that perfect medium-rare finish. If possible, choose grass-fed or organic beef for enhanced flavor and quality.

Marinating Flank Steak

Marinating flank steak is a vital step that tenderizes the meat and infuses it with flavor. A good marinade typically includes an acid (like vinegar or citrus juice), oil, and various seasonings. Here's a simple marinade recipe to get you started:

Flank Steak Marinade Recipe

• Ingredients:
  • ½ cup olive oil
  • 3 tablespoons Worcestershire sauce
  • ¼ cup fresh lime juice (about 2 limes, juiced)
  • 1 tablespoon minced garlic
  • 1 teaspoon ground cumin
  • ½ tablespoon chili powder
  • ½ teaspoon red pepper flakes
  • 1 tablespoon sugar
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly cracked black pepper
• Instructions:
  1. In a mixing bowl, whisk together all the marinade ingredients until combined.
  2. Place the flank steak in a gallon-sized zip-top bag and pour the marinade over it, ensuring it's well-coated.
  3. Seal the bag and refrigerate for at least 30 minutes, or up to 8 hours for maximum flavor.

Seasoning

If you're short on time, simply seasoning the flank steak with salt and pepper is also effective. However, a marinade enhances the flavor profile significantly.

Cooking Flank Steak in a Cast Iron Skillet

Why Use a Cast Iron Skillet?

Cast iron skillets are renowned for their ability to retain and evenly distribute heat, making them ideal for searing meat. The high heat creates a crust on the steak that locks in juices, resulting in a flavorful and tender piece of meat.

Cooking Instructions

1. Preheat the Skillet: Place your cast iron skillet on the stove over medium-high heat. Allow it to become very hot, which should take about 5 minutes.
2. Add Oil: Add a high smoke point oil, such as grapeseed or canola oil, to the skillet. Swirl it around to coat the surface.
3. Sear the Steak: Remove the flank steak from the marinade, letting any excess drip off. Carefully place it in the hot skillet. Sear for about 4-5 minutes on one side without moving it. This allows a crust to form.
4. Flip and Cook: Flip the steak using tongs and sear the other side for about 3-4 minutes. You want the internal temperature to reach around 130°F for medium-rare.
5. Check Doneness: Use an instant-read thermometer to check the internal temperature. For medium, aim for 140°F. Be careful not to overcook the flank steak, as it can become tough.
6. Rest the Steak: Once cooked to your liking, remove the steak from the skillet and place it on a cutting board. Tent it loosely with foil and let it rest for about 10 minutes. Resting allows the juices to redistribute throughout the meat.

Slicing Flank Steak

The Importance of Cutting Against the Grain

Flank steak has long muscle fibers, and slicing against the grain shortens these fibers, resulting in a more tender bite. To identify the grain, look for the direction the muscle fibers run.

1. Place the rested steak on a cutting board.
2. Using a sharp knife, slice thinly against the grain at a 45-degree angle.
3. Serve immediately or store for later use in salads, tacos, or sandwiches.

Serving Suggestions

What to Serve with Flank Steak

Flank steak pairs beautifully with a variety of sides. Here are a few suggestions:

• Garden Salad: A light salad with mixed greens, cherry tomatoes, and a vinaigrette complements the rich flavors of the steak.
• Roasted Vegetables: Seasonal roasted vegetables add color and nutrition to your plate.
• Mashed Potatoes: Creamy mashed potatoes provide a comforting side that balances the dish.
• Chimichurri Sauce: A zesty chimichurri sauce made with fresh herbs, garlic, and olive oil enhances the flavor of the steak beautifully.

Conclusion

Cooking flank steak in a cast iron skillet is a straightforward yet rewarding culinary endeavor. With a few simple steps, you can transform a humble cut of beef into a deliciously tender and flavorful centerpiece for your meal.
