Key Takeaways About How to Cook Flank Steak in Cast Iron Pan

  • Choosing a high – quality flank steak is crucial for a flavorful and tender dish.
  • Preheating the cast iron skillet before cooking helps create a delicious crust on the outside of the steak.
  • Searing the flank steak on high heat for 2 – 3 minutes per side locks in savory flavors and enhances taste.
  • Resting the cooked flank steak for 5 – 10 minutes ensures juicy and tender results when sliced against the grain.

Preparing The Flank Steak For Cooking

Choose a high-quality flank steak, season it with salt and pepper, and optionally marinate it to enhance the flavors before cooking.

Choosing A High-quality Flank Steak

The first step in cooking the perfect cast iron flank steak is selecting the right cut of meat. Quality matters greatly when it comes to steaks, and for a tender, flavorful dish, you will want to go for a premium grade flank steak.

Be sure to look for a piece that’s lean yet exhibits thin streaks of marbling – this indicates that your steak would be juicy and rich in flavor once cooked. It should also have a bright red color, firm texture, and shouldn’t exhibit any foul smell.

A good-quality flank steak can truly elevate your meal from standard to sensational. Keep this in mind while shopping at your local grocery store or butcher shop for an unforgettable weeknight dinner experience.

Seasoning The Steak With Salt And Pepper

To enhance the natural flavors of the flank steak, seasoning it with salt and pepper is a must. Before cooking, generously sprinkle both sides of the steak with kosher salt and freshly ground black pepper.

The salt helps to bring out the meat’s inherent taste while tenderizing it slightly. Meanwhile, the pepper adds a subtle kick that complements the beefy goodness.

Remember not to be too light-handed when applying the seasoning; you want enough salt and pepper to create a flavorful crust on the outside of your steak. A good rule of thumb is about 1 teaspoon each of salt and pepper per pound of meat.

Gently pat down the seasonings into the meat so they adhere well before proceeding with marinating or cooking.

Marinating The Steak (optional)

Marinating the flank steak is an optional step that can add even more flavor to your dish. Before marinating, make sure to choose a high-quality flank steak and pat it dry with paper towels.

Season the steak generously with salt and pepper on both sides. If you decide to marinate, whisk together your desired marinade ingredients like soy sauce, Worcestershire sauce, garlic, and olive oil in a bowl.

Place the seasoned flank steak in a resealable bag or shallow dish and pour the marinade over it, making sure it’s fully coated. Allow the steak to marinate in the fridge for at least 30 minutes or up to overnight for maximum flavor infusion.

When you’re ready to cook, remove the flank steak from the marinade and discard it before proceeding with searing it in your preheated cast iron skillet according to the cooking instructions mentioned above.

Cooking The Flank Steak In A Cast Iron Skillet

Let’s find out how to cook flank steak in cast iron. Preheat the cast iron skillet over medium-high heat for a few minutes to ensure it’s hot enough to sear the flank steak properly.

Preheating The Cast Iron Skillet

To ensure that your flank steak cooks evenly and develops a delicious crust, it’s crucial to preheat your cast iron skillet before adding the meat. Preheating allows the pan to reach its optimal temperature, which will help sear the steak perfectly.

Simply place the cast iron skillet over medium-high heat and let it heat up for a few minutes until it’s nice and hot. This step is essential as it creates a sizzling surface that locks in all those savory flavors while giving you that desired caramelized crust on the outside of your flank steak.

So be sure not to skip this important step when cooking your flavorful flank steak in a trusty cast iron skillet!

Searing The Steak On High Heat For 2-3 Minutes Per Side

To achieve a beautifully caramelized crust on your flank steak, searing it on high heat is crucial. Once your cast iron skillet is preheated over medium-high heat, carefully place the seasoned steak in the pan and let it sizzle away for about 2 to 3 minutes per side.

The intense heat will help create a rich brown color on the outside of the steak, adding even more flavor to each bite.

During this searing process, avoid constantly moving or flipping the steak as it will prevent proper browning. Instead, allow each side to cook undisturbed before giving it a flip. Remember that searing locks in those savory juices and enhances the overall taste of the meat.

Keep an eye out for those beautiful pink beads of moisture that start appearing on top of the steak while cooking—it’s like Mother Nature’s way of letting you know when your meat is ready! Trust your instincts and rely on these visual cues rather than solely relying on cooking times for doneness.

Adjusting The Cooking Time Based On Desired Doneness

The cooking time for flank steak in a cast iron skillet can be adjusted based on your preferred level of doneness. If you like your steak rare, it’s best to cook each side for about 2-3 minutes on high heat.

For medium-rare, add an extra minute or two per side. And if you prefer a more well-done steak, cook each side for around 4 minutes. Keep an eye out for those pink beads of moisture that indicate the steak is cooked to perfection.

Remember to reduce the heat if the skillet gets too hot during cooking and use a meat thermometer to ensure accuracy. With these simple adjustments, you can enjoy a perfectly cooked flank steak every time!

Resting And Slicing The Flank Steak

After cooking, allow the flank steak to rest for 5-10 minutes before slicing it against the grain. This ensures that the juices redistribute throughout the meat and results in a tender and flavorful steak. It is equally important as learning how to cook flank steak in cast iron.

Allowing The Steak To Rest For 5-10 Minutes

After cooking the flank steak in a hot cast iron skillet, it’s crucial to allow it to rest for about 5-10 minutes. This step is often overlooked but is essential for ensuring a juicy and tender final result.

Resting the steak allows the juices to redistribute throughout the meat, resulting in a more flavorful and enjoyable eating experience. During this time, you can cover the steak loosely with aluminum foil to help retain its heat.

Resist the temptation to cut into it right away because cutting too soon will cause all those flavorful juices to run out onto your plate instead of staying inside the meat where they belong.

Slicing The Steak Against The Grain

To achieve the perfect texture and tenderness in your flank steak, it is crucial to slice it against the grain. This means cutting perpendicular to the long muscle fibers of the steak. Slicing against the grain helps break up those tough fibers, resulting in a melt-in-your-mouth experience.

After allowing your cooked flank steak to rest for 5-10 minutes, take a moment to identify the direction of these muscle fibers running through your meat. With a sharp knife held at a slight angle, cut thin slices across those lines.

The end result should be tender pieces that are easy to chew and full of flavor.

Serving And Enjoying The Flank Steak

Grilled vegetables like asparagus or bell peppers make for colorful and nutritious additions to your plate. And if you’re looking for an extra burst of flavor, top your flank steak off with a dollop of chimichurri sauce or a drizzle of balsamic glaze.

Using A Meat Thermometer For Precise Cooking

To ensure perfectly cooked flank steak every time, using a meat thermometer for precise cooking is key. Simply relying on the timing alone can result in an overcooked or undercooked steak. Insert the meat thermometer into the thickest part of the steak, making sure it does not touch any bone or fat.

For a medium-rare flank steak, cook each side for an additional 1-2 minutes or until the internal temperature reaches 130-135 degrees Fahrenheit. This will give you a tender and juicy steak with just the right amount of pink in the center.

Investing in a meat thermometer is a small yet invaluable tool that guarantees your cast iron flank steak is cooked to perfection every time.

If you prefer a dry rub, create your own with spices like paprika, cumin, chili powder, and brown sugar for some heat and sweetness. Whichever marinade or dry rub you choose, make sure to let the flavors infuse into the flank steak for at least 30 minutes before searing it in the cast iron skillet.

Experimenting With Different Cooking Methods (grilling, Broiling, Etc.)

To add some variety to your flank steak cooking repertoire, don’t be afraid to experiment with different cooking methods. While pan-searing in a cast iron skillet is a popular choice, grilling and broiling are also great options.
