Flank steak is a flavorful and affordable cut of beef that makes for a delicious meal. While it’s often grilled or pan-fried, cooking it in the oven can be just as tasty and convenient. But the question remains – how long does it take to cook flank steak in the oven?

There are several factors that can affect the cooking time of flank steak, such as its thickness and desired level of doneness. However, a general rule of thumb is to cook it for 12-15 minutes at 425°F (218°C) for medium-rare.

To ensure that your flank steak is cooked to your desired level of doneness, use a meat thermometer to check its internal temperature. For medium-rare, the temperature should be around 135°F (57°C). For medium, aim for 145°F (63°C), and for well-done, cook until it reaches 160°F (71°C).

When cooking flank steak in the oven, there are a few tips to keep in mind:

1. Let it rest: Allow your flank steak to rest for at least five minutes after cooking before slicing into it. This will help retain its juices and make it more tender.

2. Season well: Flank steak can be quite lean, so make sure to season it well with salt, pepper, and any other herbs or spices you prefer.

3. Use a broiler pan: To prevent your flank steak from becoming too greasy or soggy, use a broiler pan with slats or a wire rack on top to allow excess fat to drip off.

Here’s a simple recipe for cooking flank steak in the oven:


  • 1 pound flank steak
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon olive oil


  1. Preheat your oven to 425°F (218°C).
  2. Pat your flank steak dry with a paper towel and season it with salt and pepper.
  3. Heat olive oil in a large oven-safe skillet over medium-high heat.
  4. Add the flank steak to the skillet and cook for 3-4 minutes per side until browned.
  5. Transfer the skillet to the preheated oven and cook for 12-15 minutes for medium-rare, or until desired level of doneness is reached.
  6. Remove from oven and let rest for at least five minutes before slicing into it.
