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 creates beautiful sear marks and ensures the steak cooks evenly, resulting in a tender, juicy masterpiece. This guide will walk you through the process, answering common questions and helping you achieve flank steak perfection.
How Do I Cook Flank Steak in Cast Iron to Make it Tender?
The key to tender flank steak lies in two things: proper preparation and cooking technique. First, choose a high-quality steak. Look for vibrant red color with good marbling. Second, don't overcook it. Flank steak is naturally lean, and overcooking will result in a tough, chewy texture. Aim for medium-rare to medium.
Before cooking, pat the steak dry with paper towels. This helps achieve a good sear. Then, season generously with salt, pepper, and any other desired spices. Garlic powder, onion powder, paprika, or a pre-made steak seasoning blend all work well. Let the steak sit at room temperature for about 30 minutes to allow it to come to equilibrium—this promotes even cooking.
Heat your cast iron skillet over high heat until it's screaming hot. Add a high-smoke-point oil, like canola or avocado oil, to the hot skillet. Once the oil shimmers, add the steak. Sear for 2-3 minutes per side to develop a beautiful crust. Then, reduce the heat to medium-high and continue cooking to your desired internal temperature, using a meat thermometer for accuracy. For medium-rare, aim for 130-135°F (54-57°C); for medium, aim for 135-140°F (57-60°C).
Finally, rest the steak for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak. Slice the steak against the grain for maximum tenderness.
What Temperature Should I Cook Flank Steak in a Cast Iron Skillet?
As mentioned above, you'll need a high heat initially to sear the steak. Your burner should be set to high until the oil shimmers and the steak begins to sear. Once you've achieved a good sear, reduce the heat to medium-high to finish cooking the steak to your desired internal temperature. Using a meat thermometer is crucial to prevent overcooking.
How Long Do You Cook Flank Steak in Cast Iron?
The cooking time for flank steak in a cast iron skillet depends on the thickness of the steak and your desired level of doneness. As a general guideline:
- Sear: 2-3 minutes per side
- Finish Cooking: An additional 4-6 minutes per side for medium-rare to medium, depending on thickness. Always use a meat thermometer to check for doneness.
Is Flank Steak Tough When Cooked in Cast Iron?
Flank steak can be tough if overcooked. However, proper cooking techniques, including searing at high heat and allowing for sufficient resting time, minimize toughness. Slicing against the grain is also essential for tenderness.
How Do I Make Flank Steak Tender After Cooking?
The best way to ensure tender flank steak is to follow the cooking instructions meticulously. However, if you find your steak slightly tougher than expected, consider using a marinade beforehand to tenderize the meat. A simple marinade with olive oil, soy sauce, garlic, and your favorite spices can make a significant difference.
What's the Best Way to Season Flank Steak for Cast Iron?
While personal preference plays a role, a simple seasoning of salt and pepper is often sufficient to highlight the natural flavor of the flank steak. However, you can experiment with various spice blends. Garlic powder, onion powder, paprika, chili powder, or even a pre-made steak seasoning blend can all add delicious depth of flavor.
By following these guidelines and tips, you'll consistently achieve perfectly cooked flank steak in your cast iron skillet – juicy, flavorful, and tender every time. Remember, practice makes perfect, so don't be afraid to experiment and find your preferred cooking method.
