How To Cook A Flat Iron Steak In The Oven?

Learn how to cook a flat iron steak in the oven to achieve a perfectly tender and juicy result, utilizing a combination of searing and baking techniques for optimal flavor and texture. This method is surprisingly simple and yields restaurant-quality results.

What Makes the Flat Iron Steak Special?

The flat iron steak, also known as a butler’s steak or oyster blade steak, is a cut of beef taken from the shoulder clod, specifically the top blade. It’s prized for its tenderness and rich, beefy flavor, often compared to a filet mignon but at a more budget-friendly price point. Properly cooked, a flat iron steak offers a fantastic eating experience.

Benefits of Oven Cooking

While grilling and pan-searing are popular methods for cooking steak, baking offers some distinct advantages:

  • Even Cooking: The oven provides a more consistent temperature, leading to more even cooking throughout the steak.
  • Temperature Control: It’s easier to monitor the internal temperature of the steak, ensuring you reach your desired level of doneness.
  • Hands-Off Approach: Once the initial sear is complete, the oven allows for a more hands-off cooking experience, freeing you up to prepare side dishes.
  • Winter-Friendly: Perfect for cooking steak indoors during colder months when grilling outside isn’t appealing.

The Secret to Oven-Baked Perfection

The key to a perfectly cooked flat iron steak in the oven is a two-stage cooking process:

  1. Searing: Achieve a beautiful, flavorful crust on the stovetop in a hot pan.
  2. Baking: Finish cooking the steak in the oven to the desired internal temperature.

This combination of searing and baking yields a steak that is both crispy on the outside and juicy on the inside.

Step-by-Step Guide: Cooking Flat Iron Steak in the Oven

Follow these simple steps for foolproof results:

  1. Prepare the Steak: Remove the steak from the refrigerator at least 30 minutes before cooking. This allows it to come to room temperature, promoting even cooking. Pat the steak dry with paper towels and season generously with salt and pepper.

  2. Preheat and Prepare: Preheat your oven to 400°F (200°C). Place an oven-safe skillet (cast iron is ideal) on the stovetop over high heat. Add a tablespoon or two of high-heat oil, such as canola or avocado oil.

  3. Sear the Steak: Once the oil is shimmering and very hot, carefully place the steak in the skillet. Sear for 2-3 minutes per side, or until a deep brown crust forms.

  4. Bake to Perfection: Transfer the skillet to the preheated oven. Bake until the steak reaches your desired internal temperature:

    Doneness Internal Temperature
    Rare 125-130°F (52-54°C)
    Medium-Rare 130-135°F (54-57°C)
    Medium 135-145°F (57-63°C)
    Medium-Well 145-155°F (63-68°C)
    Well-Done 155°F+ (68°C+)
  5. Rest and Serve: Remove the skillet from the oven and transfer the steak to a cutting board. Tent loosely with foil and let rest for 5-10 minutes. This allows the juices to redistribute, resulting in a more tender and flavorful steak. Slice against the grain and serve immediately.

Common Mistakes to Avoid

  • Skipping the Rest: Resting the steak is crucial for retaining its juices. Don’t skip this step!
  • Overcooking: Use a meat thermometer to accurately monitor the internal temperature and avoid overcooking. Flat iron steak is best enjoyed medium-rare to medium.
  • Using a Cold Pan: A hot pan is essential for achieving a good sear. Be patient and let the pan heat up properly before adding the steak.
  • Crowding the Pan: If you’re cooking multiple steaks, don’t overcrowd the pan. This will lower the temperature and prevent the steak from searing properly. Cook in batches if necessary.
  • Not Slicing Against the Grain: The flat iron steak has a noticeable grain. Slicing against the grain shortens the muscle fibers, making the steak more tender and easier to chew.

Adding Flavor Enhancements

  • Garlic and Herbs: Add a few cloves of crushed garlic and sprigs of fresh thyme or rosemary to the pan during the last few minutes of searing to infuse the steak with flavor.
  • Butter Basting: During the last few minutes of baking, add a knob of butter to the pan and baste the steak with the melted butter. This will add richness and flavor.
  • Marinades: Marinating the steak for a few hours before cooking can add extra flavor and tenderize the meat.

Frequently Asked Questions (FAQs)

Can I use a different type of oil for searing?

Yes, you can use other high-heat oils such as grapeseed oil or refined coconut oil. Avoid using olive oil, as it has a low smoke point and can burn easily. Consider using clarified butter (ghee) for a richer flavor.

How long does it take to cook a flat iron steak in the oven?

The cooking time will vary depending on the thickness of the steak and your desired level of doneness. Generally, it takes about 5-10 minutes in the oven to reach medium-rare for a 1-inch thick steak. Always use a meat thermometer for accurate results.

What is the best way to slice a flat iron steak?

Always slice against the grain. Look for the direction of the muscle fibers and cut perpendicular to them. This will make the steak more tender and easier to chew.

Can I cook a frozen flat iron steak in the oven?

It’s not recommended to cook a frozen flat iron steak directly in the oven. Thawing the steak completely before cooking is crucial for even cooking and optimal results.

What side dishes go well with flat iron steak?

Flat iron steak pairs well with a variety of side dishes, such as roasted vegetables (asparagus, Brussels sprouts, carrots), mashed potatoes, creamy polenta, or a simple salad.

Can I use a regular skillet instead of a cast iron skillet?

While cast iron is ideal due to its excellent heat retention, you can use a regular oven-safe skillet. Ensure the skillet is oven-safe and can withstand high temperatures.

How do I know when the steak is done without a meat thermometer?

While a meat thermometer is highly recommended, you can use the touch test. Press the center of the steak with your finger. If it feels soft and yielding, it’s likely rare. If it feels slightly firmer, it’s medium-rare, and so on.

Can I marinate the flat iron steak before cooking?

Yes, marinating can add flavor and tenderize the steak. Use a marinade with acidic ingredients (such as vinegar or citrus juice) to help break down the muscle fibers. Marinate for at least 30 minutes, but no more than 24 hours.

What’s the best way to store leftover flat iron steak?

Let the steak cool completely, then store it in an airtight container in the refrigerator for up to 3-4 days.

How do I reheat leftover flat iron steak?

Reheat leftover steak gently to avoid drying it out. A low oven (250°F) or a warm skillet with a little bit of oil is ideal.

Is flat iron steak a healthy option?

Flat iron steak is a good source of protein, iron, and zinc. However, it’s also relatively high in fat, so consume it in moderation as part of a balanced diet.

Is there a difference in taste between a flat iron steak cooked in the oven vs. on a grill?

While both methods can produce delicious results, grilling often imparts a smoky flavor that’s difficult to replicate in the oven. However, the oven method provides more consistent temperature control, leading to even cooking.Ultimately the better option is a matter of preference. If it’s how to cook a flat iron steak in the oven versus on a grill, the oven provides more cooking precision.
