When it comes to cooking a delicious and tender flat iron steak, the oven is a great option. Cooking a flat iron steak in the oven at 350 degrees Fahrenheit can result in a perfectly cooked steak with a nice crust on the outside and a juicy interior. However, the cooking time can vary depending on several factors, including the thickness of the steak, the level of doneness desired, and the oven’s temperature accuracy. In this article, we will explore the best ways to cook a flat iron steak in the oven at 350 degrees Fahrenheit and provide you with a detailed guide on how to achieve the perfect doneness.

Understanding Flat Iron Steak

Before we dive into the cooking process, it’s essential to understand what a flat iron steak is and what makes it unique. A flat iron steak is a cut of beef that comes from the shoulder area of the cow. It is known for its rich flavor, tender texture, and affordability. The flat iron steak is also relatively lean, making it a popular choice for health-conscious meat lovers. One of the key characteristics of a flat iron steak is its triangular shape, which can make it a bit tricky to cook evenly. However, with the right techniques and cooking methods, you can achieve a perfectly cooked flat iron steak that is sure to impress.

Choosing the Right Flat Iron Steak

When selecting a flat iron steak, there are a few things to keep in mind. First, look for a steak that is at least 1-1.5 inches thick. This will ensure that the steak cooks evenly and retains its juiciness. Next, check the color of the steak. A good flat iron steak should have a deep red color with a slight marbling of fat throughout. This marbling will help to keep the steak moist and flavorful during cooking. Finally, consider the grade of the steak. While a higher-grade steak may be more expensive, it will generally have a more tender and flavorful texture.

Prepping the Steak for Cooking

Before cooking the flat iron steak, it’s essential to prep it properly. Start by bringing the steak to room temperature. This will help the steak cook more evenly and prevent it from cooking too quickly on the outside. Next, season the steak with your desired seasonings. A good rule of thumb is to use a combination of salt, pepper, and any other seasonings you like. Be sure to coat the steak evenly, making sure to get some seasoning on both sides. Finally, heat a skillet or oven-safe pan over high heat and add a small amount of oil. Sear the steak for 1-2 minutes on each side, or until a nice crust forms. This will help to lock in the juices and create a flavorful crust on the steak.

Cooking the Flat Iron Steak in the Oven

Now that the steak is prepped and seared, it’s time to cook it in the oven. Preheat your oven to 350 degrees Fahrenheit. Place the steak in the oven and cook for 10-15 minutes per pound, or until the steak reaches your desired level of doneness. Use a meat thermometer to check the internal temperature of the steak. For medium-rare, the internal temperature should be around 130-135 degrees Fahrenheit. For medium, the internal temperature should be around 140-145 degrees Fahrenheit. For medium-well, the internal temperature should be around 150-155 degrees Fahrenheit. For well-done, the internal temperature should be around 160-170 degrees Fahrenheit.

Cooking Times for Flat Iron Steak

The cooking time for a flat iron steak can vary depending on the thickness of the steak and the level of doneness desired. Here is a general guide to cooking times for flat iron steak:

  • 1-1.5 inches thick: 10-12 minutes per pound for medium-rare, 12-15 minutes per pound for medium, 15-18 minutes per pound for medium-well, and 18-20 minutes per pound for well-done
  • 1.5-2 inches thick: 12-15 minutes per pound for medium-rare, 15-18 minutes per pound for medium, 18-20 minutes per pound for medium-well, and 20-22 minutes per pound for well-done

Letting the Steak Rest

Once the steak is cooked to your desired level of doneness, remove it from the oven and let it rest for 5-10 minutes. This is an important step, as it allows the juices to redistribute and the steak to retain its tenderness. During this time, the steak will continue to cook a bit, so it’s essential to check the internal temperature again before serving. If the steak has cooled too much, you can always put it back in the oven for a few minutes to warm it up.

Tips and Variations for Cooking Flat Iron Steak

While cooking a flat iron steak in the oven at 350 degrees Fahrenheit is a great way to achieve a delicious and tender steak, there are a few tips and variations to keep in mind. First, make sure to not overcrowd the pan or oven, as this can cause the steak to steam instead of sear. Next, consider adding some aromatics to the pan, such as garlic, onions, or herbs, to add extra flavor to the steak. Finally, don’t be afraid to experiment with different seasonings and marinades to find the perfect flavor combination for your flat iron steak.

In conclusion, cooking a flat iron steak in the oven at 350 degrees Fahrenheit is a great way to achieve a delicious and tender steak. By following the tips and guidelines outlined in this article, you can create a perfectly cooked flat iron steak that is sure to impress. Remember to choose the right steak, prep it properly, and cook it to the right level of doneness. With a little practice and patience, you’ll be a flat iron steak expert in no time.

What is a flat iron steak and why is it a popular choice for oven cooking?

A flat iron steak is a cut of beef that comes from the shoulder area of the cow, known for its tenderness and rich flavor. It is a popular choice for oven cooking because of its uniform thickness, which allows for even cooking and a consistent texture throughout. The flat iron steak is also relatively lean, making it a great option for those looking for a healthier red meat option. Additionally, its mild flavor profile makes it an excellent canvas for a variety of seasonings and marinades.

When cooked in the oven, a flat iron steak can be prepared to a range of doneness levels, from rare to well-done, making it a versatile option for different tastes and preferences. The oven’s dry heat also helps to caramelize the steak’s natural sugars, creating a crispy crust on the outside while locking in juices on the inside. With proper cooking techniques and attention to temperature and timing, a flat iron steak can be transformed into a mouth-watering, restaurant-quality dish that is sure to impress even the most discerning palates.

What are the key factors to consider when selecting a flat iron steak for oven cooking?

When selecting a flat iron steak for oven cooking, there are several key factors to consider. First and foremost, look for a steak that is at least 1-1.5 inches thick, as this will allow for even cooking and prevent the steak from becoming too thin and overcooked. Additionally, choose a steak with a good balance of marbling, as this will add flavor and tenderness to the final dish. It’s also important to consider the grade of the steak, with options ranging from choice to prime, each offering varying levels of quality and flavor.

The origin and breed of the cattle can also impact the flavor and quality of the steak, with options like grass-fed or wagyu offering unique characteristics and nutritional profiles. Finally, consider the packaging and handling of the steak, opting for steaks that are wrapped in plastic or paper to prevent moisture loss and contamination. By taking the time to carefully select a high-quality flat iron steak, you can ensure a delicious and memorable dining experience that showcases the full potential of this exceptional cut of beef.

How do I prepare a flat iron steak for oven cooking at 350 degrees?

To prepare a flat iron steak for oven cooking at 350 degrees, start by bringing the steak to room temperature, allowing it to sit out for 30-45 minutes before cooking. This helps to ensure even cooking and prevents the steak from cooking too quickly on the outside. Next, season the steak liberally with salt, pepper, and any other desired seasonings or marinades, making sure to coat the steak evenly on all sides. You can also add a small amount of oil to the steak to enhance browning and flavor.

Once the steak is seasoned, place it on a broiler pan or rimmed baking sheet lined with aluminum foil or parchment paper, leaving a small amount of space between the steak and the pan to allow for air circulation. If desired, add aromatics like garlic, herbs, or lemon slices to the pan to infuse the steak with additional flavor. Finally, place the steak in the preheated oven and cook to the desired level of doneness, using a meat thermometer to check for internal temperatures and ensure food safety.

What is the recommended cooking time for a flat iron steak in the oven at 350 degrees?

The recommended cooking time for a flat iron steak in the oven at 350 degrees will depend on the thickness of the steak and the desired level of doneness. As a general guideline, a 1-1.5 inch thick flat iron steak will take around 12-15 minutes to cook to medium-rare, 15-18 minutes to cook to medium, and 18-20 minutes to cook to medium-well or well-done. However, it’s essential to use a meat thermometer to check for internal temperatures, as this will provide a more accurate indication of doneness.

For medium-rare, the internal temperature should reach 130-135 degrees Fahrenheit, while medium should reach 140-145 degrees Fahrenheit. Medium-well and well-done steaks should reach internal temperatures of 150-155 degrees Fahrenheit and 160 degrees Fahrenheit or above, respectively. It’s also important to note that the steak will continue to cook slightly after it’s removed from the oven, so it’s better to err on the side of undercooking rather than overcooking. By using a combination of cooking time and internal temperature, you can achieve a perfectly cooked flat iron steak that meets your desired level of doneness.

How do I ensure a crispy crust on my flat iron steak when cooking it in the oven?

To ensure a crispy crust on your flat iron steak when cooking it in the oven, it’s essential to create a dry surface on the steak before cooking. This can be achieved by patting the steak dry with paper towels, removing excess moisture that can prevent browning. Additionally, make sure the steak is at room temperature, as this will help the steak cook more evenly and prevent the outside from cooking too quickly. You can also add a small amount of oil to the steak, which will help to enhance browning and create a crispy crust.

Another key factor in achieving a crispy crust is to use high heat for a short period, either by broiling the steak for a few minutes before finishing it in the oven or by using a hot skillet to sear the steak before transferring it to the oven. This will create a flavorful, caramelized crust on the outside of the steak, while locking in juices on the inside. Finally, avoid overcrowding the pan or oven, as this can prevent air from circulating and prevent the steak from browning evenly. By following these tips, you can achieve a delicious, crispy crust on your flat iron steak that adds texture and flavor to the final dish.

Can I cook a flat iron steak in the oven without a broiler pan or rimmed baking sheet?

While a broiler pan or rimmed baking sheet is recommended for cooking a flat iron steak in the oven, it’s not strictly necessary. You can cook a flat iron steak directly on the oven rack, using a piece of aluminum foil or parchment paper to catch any drips or juices. However, this method can be messier and may require more cleanup, as the steak’s juices can spill onto the oven floor. Additionally, cooking the steak directly on the oven rack can lead to uneven cooking, as the steak may not be able to cook evenly on all sides.

If you don’t have a broiler pan or rimmed baking sheet, you can also use a cast-iron skillet or other oven-safe pan to cook the steak. Simply preheat the skillet in the oven before adding the steak, then cook the steak to the desired level of doneness. This method can help to create a crispy crust on the steak, while also containing any juices or drips. Regardless of the method you choose, make sure to use a meat thermometer to check for internal temperatures and ensure food safety, and always let the steak rest for a few minutes before slicing and serving.

How do I store and reheat leftover flat iron steak cooked in the oven?

To store leftover flat iron steak cooked in the oven, make sure to cool the steak to room temperature within a few hours of cooking, then wrap it tightly in plastic wrap or aluminum foil and refrigerate or freeze. Cooked steak can be safely stored in the refrigerator for up to 3-4 days or frozen for up to 2-3 months. When reheating leftover steak, it’s essential to heat it to an internal temperature of at least 165 degrees Fahrenheit to ensure food safety.

To reheat leftover flat iron steak, you can use a variety of methods, including oven reheating, pan-frying, or microwaving. For oven reheating, wrap the steak in foil and heat it in a preheated oven at 300-350 degrees Fahrenheit for 10-15 minutes, or until the steak reaches the desired temperature. For pan-frying, slice the steak thinly and heat it in a skillet with a small amount of oil over medium heat, stirring frequently to prevent burning. Microwaving is also an option, but be careful not to overheat the steak, as this can lead to dryness and toughness. Regardless of the reheating method, make sure to slice the steak against the grain and serve it immediately to ensure the best flavor and texture.
