Understanding Flank Steak

Before we dive into the cooking process, it’s essential to understand the characteristics of flank steak. Flank steak is a lean cut of beef that comes from the abdominal muscles of the cow. It is known for its bold flavor and chewy texture, making it a popular choice for fajitas, steak salads, and other dishes where a robust flavor is desired.

One of the key things to keep in mind when cooking flank steak is that it is a relatively thin cut of meat. This means that it can cook quickly, and it’s easy to overcook it if you’re not careful. To avoid overcooking your flank steak, it’s crucial to cook it to the right temperature and to use a thermometer to ensure that it reaches a safe internal temperature.

Choosing the Right Cast Iron Skillet

Some things to look for when choosing a cast iron skillet for cooking flank steak include:

• A heavy bottom: A heavy bottom will help the skillet to retain heat evenly and prevent hotspots from forming.
• A smooth surface: A smooth surface will help to prevent the steak from sticking to the skillet and make it easier to flip and remove.
• A comfortable handle: A comfortable handle will make it easier to maneuver the skillet and prevent accidents.

Now that we’ve covered the basics of flank steak and cast iron skillets, let’s move on to the cooking process. Cooking flank steak in a cast iron skillet is a relatively straightforward process that requires some basic cooking skills and attention to temperature.

Here’s a step-by-step guide to cooking flank steak in a cast iron skillet:

Step 1: Preheat the Skillet

Preheating the skillet is an essential step in cooking flank steak. To preheat the skillet, place it over high heat and let it heat up for 5-10 minutes. You can test the heat of the skillet by flicking a few drops of water onto the surface. If the water sizzles and evaporates quickly, the skillet is ready to go.

Step 2: Season the Steak

While the skillet is heating up, season the flank steak with your desired seasonings. Some popular seasonings for flank steak include salt, pepper, garlic powder, and paprika.

Step 3: Add Oil to the Skillet

Once the skillet is hot, add a small amount of oil to the surface. You can use any type of oil you like, but some popular options include olive oil, coconut oil, and avocado oil.

Step 4: Sear the Steak

Place the flank steak in the skillet and sear it for 3-4 minutes per side. You want to get a nice crust on the steak, so don’t be afraid to let it cook for a few minutes. Use tongs or a spatula to flip the steak and cook the other side.

Step 5: Finish Cooking the Steak

After searing the steak, reduce the heat to medium-low and continue cooking it to your desired level of doneness. Use a thermometer to check the internal temperature of the steak. The recommended internal temperature for flank steak is at least 135°F (57°C) for medium-rare, 145°F (63°C) for medium, and 155°F (68°C) for medium-well or well-done.
