Flank steak, a lean and flavorful 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. This guide will walk you through the process, ensuring you achieve perfectly cooked flank steak every time. We'll address common questions and concerns to help you master this technique.
What's the Best Way to Cook Flank Steak in Cast Iron?
The key to a great cast iron flank steak lies in proper preparation and technique. Here’s a step-by-step guide:
-
Prepare the Steak: Pat the flank steak dry with paper towels. This helps achieve a good sear. Season generously with salt and freshly ground black pepper. You can also add other spices like garlic powder, onion powder, or paprika, depending on your preference.
-
Heat the Skillet: Place your cast iron skillet over medium-high heat. Let it get screaming hot – this is crucial for a good sear. Add a high-smoke-point oil, such as canola, grapeseed, or avocado oil. The oil should shimmer before adding the steak.
-
Sear the Steak: Carefully place the steak in the hot skillet. Sear for 3-4 minutes per side, undisturbed, to develop a beautiful crust. Avoid moving the steak around too much during searing.
-
Reduce Heat and Finish Cooking: Once seared, reduce the heat to medium. Continue cooking to your desired internal temperature, using a meat thermometer for accuracy. Flank steak is best cooked to medium-rare (130-135°F) or medium (135-140°F) to avoid becoming tough.
-
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 Against the Grain: Slice the steak thinly against the grain (the direction the muscle fibers run). This makes the steak much more tender.
How Long Do You Cook Flank Steak in a Cast Iron Skillet?
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 around 8-12 minutes total, but always use a meat thermometer to ensure it reaches your desired internal temperature.
How Do You Keep Flank Steak Tender When Cooking in Cast Iron?
Tenderness is key with flank steak. Here's how to ensure it stays tender:
- Don't Overcook: Overcooked flank steak will be tough and chewy. Use a meat thermometer to monitor the internal temperature carefully.
- Rest the Steak: Allowing the steak to rest is crucial for retaining its juices and ensuring tenderness.
- Slice Against the Grain: This simple step makes a huge difference in tenderness.
What Temperature Should Flank Steak Be Cooked To?
Flank steak is best cooked to medium-rare (130-135°F) or medium (135-140°F). Cooking it beyond medium will make it tough.
Can You Cook Flank Steak in a Cast Iron Skillet Without Oil?
While you can technically cook flank steak in a cast iron skillet without oil, it's not recommended. Oil helps prevent sticking and promotes a good sear, which is essential for flavor and texture.

Your perfectly cooked cast iron flank steak is versatile and pairs well with various sides. Consider serving it with:
- Roasted vegetables
- Mashed potatoes
- Grilled asparagus
