Flank steak, known for its rich flavor and lean texture, becomes truly exceptional when cooked in a cast iron skillet. The even heat distribution of cast iron creates a beautiful sear, locking in juices and resulting in a tender, flavorful steak. This comprehensive guide will walk you through the process, addressing common questions and ensuring your flank steak turns out perfectly every time.
What's the Best Way to Cook Flank Steak in Cast Iron?
The key to a delicious cast iron flank steak lies in a combination of proper preparation, high heat searing, and careful cooking to achieve the desired level of doneness. We'll cover each step in detail below. Remember, patience is key—rushing the process can lead to a tough, dry steak.
Preparing Your Flank Steak
- Bring it to Room Temperature: Take your steak out of the refrigerator at least 30 minutes before cooking. This allows for even cooking throughout.
- Pat it Dry: Use paper towels to thoroughly pat the steak dry. Excess moisture will prevent a good sear.
- Season Generously: Season liberally with salt and freshly ground black pepper. You can also experiment with other seasonings like garlic powder, onion powder, paprika, or your favorite steak rub.
Searing the Flank Steak in Cast Iron
- Preheat Your Skillet: Place your cast iron skillet over high heat. Let it get screaming hot—this is crucial for a good sear. Add a high-smoke-point oil like canola, grapeseed, or avocado oil.
- Sear the Steak: Once the oil is shimmering, carefully place the steak in the hot skillet. Do not move it for at least 3-4 minutes. This allows for a proper sear to develop.
- Flip and Sear: Flip the steak and sear the other side for another 3-4 minutes.
- Reduce Heat (Optional): If you prefer a more well-done steak, reduce the heat to medium and continue cooking, flipping occasionally, until the steak reaches your desired internal temperature.
Checking for Doneness
Use a meat thermometer for the most accurate results. Here's a general guide:
- Rare: 125-130°F
- Medium-Rare: 130-135°F
- Medium: 135-140°F
- Medium-Well: 140-145°F
- Well-Done: 145°F+
Remember that flank steak will continue to cook slightly after it's removed from the heat (carryover cooking).
Resting is Key
Once the steak reaches your desired internal temperature, remove it from the skillet and let it rest on a cutting board for at least 10 minutes, loosely tented with foil. This allows the juices to redistribute, resulting in a more tender and flavorful steak.
How Long Does it Take to Cook Flank Steak in Cast Iron?
The cooking time depends on the thickness of your steak and your desired level of doneness. A 1-inch thick flank steak will typically take 8-12 minutes total cooking time, including searing. Always use a meat thermometer to ensure it's cooked to your liking.
What Temperature Should I Cook Flank Steak in a Cast Iron Skillet?
You should cook flank steak in a cast iron skillet over high heat initially to achieve a good sear. Then, you can reduce the heat to medium if needed to cook the steak to your desired internal temperature. Maintaining a high initial temperature is vital for that perfect crust.
How Do I Make Flank Steak Tender?
The key to tender flank steak is to cook it to the correct internal temperature and then let it rest properly. Marinating the steak beforehand can also help tenderize it, infusing it with flavor at the same time. Slicing against the grain after resting is crucial for optimal tenderness.
Can I Marinate Flank Steak Before Cooking it in Cast Iron?
Yes! Marinating flank steak before cooking it in cast iron is highly recommended. A marinade helps tenderize the meat and adds extra flavor. Experiment with different marinades to find your favorite combination of herbs, spices, and acids.
What's the Best Cut of Steak to Cook in Cast Iron?
While flank steak is excellent in cast iron, other cuts also work well. Ribeye, New York strip, and sirloin are all popular choices. The key is to adjust cooking times based on the thickness and cut of the steak.
By following these steps, you'll master the art of cooking a perfect flank steak in your cast iron skillet. Enjoy!
