Cooking Flank Steak in a Cast Iron Skillet: A Game-Changing Method

Flank steak, a lean and flavorful cut of beef, is often overlooked in favor of more popular cuts like ribeye or sirloin. However, when cooked correctly, flank steak can be a truly delicious and satisfying meal. One of the best ways to cook flank steak is in a cast iron skillet, which allows for a crispy crust to form on the outside while locking in the juices on the inside. In this article, we’ll explore the benefits of cooking flank steak in a cast iron skillet and provide a step-by-step guide on how to do it.

The Benefits of Cooking Flank Steak in a Cast Iron Skillet

Cooking flank steak in a cast iron skillet offers several benefits, including:

Even Heat Distribution

Cast iron skillets are known for their ability to distribute heat evenly, which is essential for cooking flank steak. This ensures that the steak is cooked consistently throughout, with no hot or cold spots.

Crispy Crust Formation

The high heat retention of cast iron skillets allows for a crispy crust to form on the outside of the steak, which adds texture and flavor to the dish.

Retains Juices

The iron in the skillet reacts with the acidity in the steak, helping to lock in the juices and keep the meat moist and tender.

Versatility

Cast iron skillets can be used on the stovetop, in the oven, or even on a camping trip over a campfire, making them a versatile cooking vessel.

Choosing the Right Flank Steak

When selecting a flank steak, look for the following characteristics:

Thickness

Opt for a steak that is at least 1/4 inch thick, but no more than 1/2 inch thick. This will ensure that the steak cooks evenly and is not too thick to cook through.

Marbling

Choose a steak with a moderate amount of marbling, as this will add flavor and tenderness to the dish.

Color

Select a steak with a rich, red color, as this indicates a higher quality cut of meat.

Preparing the Flank Steak

Before cooking the flank steak, it’s essential to prepare it properly. Here’s a step-by-step guide:

Trimming the Steak

Trim any excess fat or connective tissue from the steak, as this can make the steak tough and chewy.

Seasoning the Steak

Season the steak with a mixture of salt, pepper, and any other desired herbs or spices. Let the steak sit at room temperature for at least 30 minutes to allow the seasonings to penetrate the meat.

Bringing the Steak to Room Temperature

Remove the steak from the refrigerator and let it sit at room temperature for at least 30 minutes before cooking. This will help the steak cook more evenly.

Cooking the Flank Steak in a Cast Iron Skillet

Now that the steak is prepared, it’s time to cook it in the cast iron skillet. Here’s a step-by-step guide:

Heating the Skillet

Heat the cast iron skillet over high heat until it reaches a temperature of at least 400°F (200°C). You can test the heat by flicking a few drops of water onto the skillet – if they sizzle and evaporate quickly, the skillet is ready.

Adding Oil to the Skillet

Add a small amount of oil to the skillet, just enough to coat the bottom. You can use any type of oil with a high smoke point, such as avocado oil or grapeseed oil.

Searing the Steak

Place the steak in the skillet and sear for 3-4 minutes per side, depending on the thickness of the steak. You want to get a nice crust on the steak, but be careful not to overcook it.

Finishing the Steak

After searing the steak, reduce the heat to medium-low and continue cooking to your desired level of doneness. Use a meat thermometer to check the internal temperature of the steak – for medium-rare, the temperature should be at least 130°F (54°C).

Resting the Steak

Once the steak is cooked to your liking, remove it from the skillet and let it rest for at least 5 minutes. This will allow the juices to redistribute and the steak to retain its tenderness.

Slicing and Serving

Slice the steak against the grain and serve immediately. You can serve the steak on its own or with your favorite sides, such as roasted vegetables or mashed potatoes.

Tips and Variations

Here are a few tips and variations to keep in mind when cooking flank steak in a cast iron skillet:

Using a Marinade

Consider marinating the steak in your favorite seasonings and acids, such as soy sauce and vinegar, before cooking. This will add extra flavor to the dish.

Adding Aromatics

Add some aromatics, such as garlic and onions, to the skillet before cooking the steak. This will add extra flavor to the dish.

Using Different Cooking Methods

Consider using different cooking methods, such as grilling or pan-frying, to add extra texture and flavor to the dish.

Conclusion

Cooking flank steak in a cast iron skillet is a game-changing method that offers a crispy crust, even heat distribution, and a tender, juicy interior. By following the steps outlined in this article, you can create a delicious and satisfying meal that is sure to impress. Whether you’re a seasoned chef or a beginner cook, cooking flank steak in a cast iron skillet is a technique that is sure to become a staple in your kitchen.

Note: The internal temperature of the steak will continue to rise after it is removed from the skillet, so it’s essential to remove it from the heat when it reaches an internal temperature that is 5°F (3°C) lower than your desired level of doneness.

What is the ideal temperature for cooking flank steak in a cast iron skillet?

The ideal temperature for cooking flank steak in a cast iron skillet is between 400°F to 450°F (200°C to 230°C). This high heat is necessary to achieve a nice crust on the steak while cooking the interior to the desired level of doneness. Make sure to preheat the skillet for at least 10-15 minutes before adding the steak to ensure it reaches the optimal temperature.

It’s essential to note that the temperature may vary depending on the thickness of the steak and personal preference. If you prefer your steak more well-done, you may need to reduce the heat to prevent burning the exterior. On the other hand, if you prefer it rare, you can increase the heat to achieve a quicker sear.

How do I prevent the flank steak from sticking to the cast iron skillet?

To prevent the flank steak from sticking to the cast iron skillet, make sure to season the skillet properly before cooking. Apply a thin layer of oil to the preheated skillet and let it heat up for a minute or two. This will create a non-stick surface that will prevent the steak from sticking. Additionally, pat the steak dry with a paper towel before cooking to remove excess moisture.

Another crucial step is to not overcrowd the skillet. Cook the steak one at a time, depending on the size of your skillet. This will ensure that the steak has enough room to cook evenly and prevent it from sticking to the skillet. If you do experience sticking, don’t panic. Simply adjust the heat and gently nudge the steak with a spatula to loosen it.
