Flank steak, a flavorful and relatively inexpensive cut, becomes truly exceptional when cooked in a cast iron skillet. The even heat distribution of cast iron sears the steak beautifully, creating a delicious crust while keeping the inside tender and juicy. This guide will walk you through the process, answering common questions and providing tips for achieving flank steak perfection.
How Do You Cook Flank Steak in a Cast Iron Skillet?
Cooking flank steak in cast iron is all about achieving a good sear and controlling the internal temperature. Here's a step-by-step guide:
-
Prepare the Steak: Pat the flank steak dry with paper towels. This is crucial for a good sear. Season generously with salt and freshly ground black pepper. You can also add other seasonings like garlic powder, onion powder, or your favorite steak rub.
-
Heat the Skillet: Place your cast iron skillet over high heat. Let it get screaming hot – you should see a slight haze when you add a drop of water to the surface and it evaporates instantly. Add a high-smoke-point oil, such as canola or grapeseed oil, to the hot skillet.
-
Sear the Steak: Carefully place the flank steak in the hot skillet. Sear for 2-3 minutes per side, undisturbed, to develop a beautiful crust. Don't overcrowd the pan; work in batches if necessary.
-
Reduce Heat and Continue Cooking: Once seared, reduce the heat to medium-high. Continue cooking to your desired level of doneness, using a meat thermometer to check the internal temperature. Flank steak is best cooked to medium-rare (130-135°F) or medium (135-140°F) to avoid becoming tough. Cooking time will depend on the thickness of your steak and your desired doneness.
-
Rest the Steak: Once cooked, remove the steak from the skillet and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak.
-
Slice and Serve: Slice the steak thinly, against the grain, for optimal tenderness. Serve immediately and enjoy!
What Temperature Should I Cook Flank Steak to?
The ideal internal temperature for flank steak is between 130-140°F. Cooking it to medium-rare (130-135°F) or medium (135-140°F) will result in the most tender and flavorful steak. Using a meat thermometer is essential for accurate temperature control. Overcooking flank steak will result in a tough and chewy texture.
How Long Does It Take to Cook Flank Steak in a Cast Iron Skillet?
The cooking time for flank steak in a cast iron skillet varies depending on the thickness of the steak and your desired level of doneness. As a general guideline, expect to sear for 2-3 minutes per side, and then cook for an additional 4-6 minutes per side for medium-rare to medium doneness. Always use a meat thermometer to ensure the steak reaches your desired internal temperature.
Can I Marinate Flank Steak Before Cooking It in Cast Iron?
Yes! Marinating flank steak before cooking enhances its flavor and tenderness. A simple marinade of soy sauce, olive oil, garlic, and ginger works wonders. Marinating times can range from 30 minutes to overnight, depending on your preference.
How Do I Make Sure My Flank Steak Isn't Tough?
The key to a tender flank steak is to cook it to the correct temperature and to slice it against the grain. Using a meat thermometer to ensure the steak reaches the ideal internal temperature is crucial. Allowing the steak to rest for at least 10 minutes before slicing also helps to improve tenderness. Finally, slicing against the grain breaks down the muscle fibers, resulting in a much more tender eating experience.
What Side Dishes Go Well with Cast Iron Flank Steak?
Cast iron flank steak pairs well with a variety of side dishes. Some popular options include:
- Roasted vegetables: Asparagus, broccoli, and Brussels sprouts all complement the rich flavor of the steak.
- Potato salad: A creamy potato salad provides a refreshing contrast to the savory steak.
- Grilled corn on the cob: Sweet corn adds a touch of sweetness to balance the steak's savory notes.
- Simple green salad: A fresh salad with a light vinaigrette cleanses the palate between bites of steak.
By following these tips and techniques, you can easily cook a delicious and tender flank steak in your cast iron skillet. Enjoy!
