Preparing the Flat Iron Steak for the Oven
Before placing the flat iron steak in the oven, it is essential to prepare it properly to enhance flavor and ensure even cooking. Start by patting the steak dry with paper towels to remove any excess moisture, which helps achieve a better sear and crust. Next, season the steak generously with salt and freshly ground black pepper. For added flavor, consider incorporating other spices or herbs such as garlic powder, smoked paprika, or fresh rosemary.
Allow the steak to come to room temperature by resting it outside the refrigerator for about 20 to 30 minutes. This step promotes even cooking by reducing the temperature difference between the meat and the oven.
If you prefer, marinate the steak for at least 30 minutes or up to 4 hours in the refrigerator before cooking. A simple marinade might include olive oil, minced garlic, soy sauce, Worcestershire sauce, and a touch of lemon juice. After marinating, pat the steak dry again to prevent steaming during cooking.
Searing the Flat Iron Steak
Searing the steak before oven cooking is critical to develop a flavorful crust and lock in juices. Use a heavy-bottomed oven-safe skillet, such as cast iron, and heat it over medium-high heat until very hot.
Add a small amount of high smoke point oil, like canola or grapeseed oil, to the pan. When the oil is shimmering, place the steak in the pan without overcrowding. Sear each side for 2 to 3 minutes until a rich brown crust forms. Avoid moving the steak during this time to ensure proper caramelization.
Sear the edges briefly by holding the steak with tongs to render any fat and create additional flavor. Once seared, transfer the skillet directly to the preheated oven to finish cooking.
Oven Cooking Techniques and Temperature Guidelines
Cooking flat iron steak in the oven involves controlling time and temperature to achieve the desired doneness while preserving tenderness. The oven temperature should generally be set between 375°F (190°C) and 425°F (220°C), depending on steak thickness and preferred doneness.
- A lower temperature (375°F) allows for more gradual cooking, reducing the risk of overcooking.
- A higher temperature (425°F) finishes the steak quickly and can enhance crust development post-sear.
Use a meat thermometer to monitor internal temperature accurately. The USDA recommends a minimum internal temperature of 145°F (63°C) for beef steaks, followed by a resting period.
Below is a guide for internal temperatures and corresponding doneness levels:
| Doneness | Internal Temperature (°F) | Internal Temperature (°C) | Description |
|---|---|---|---|
| Rare | 120-125°F | 49-52°C | Cool, red center |
| Medium Rare | 130-135°F | 54-57°C | Warm, red center |
| Medium | 140-145°F | 60-63°C | Warm, pink center |
| Medium Well | 150-155°F | 65-68°C | Slightly pink center |
| Well Done | 160°F and above | 71°C and above | Little or no pink |
Place the skillet with the seared steak in the oven and cook for approximately 5 to 10 minutes, depending on thickness and desired doneness. Begin checking the internal temperature at the 5-minute mark to avoid overcooking.
Resting and Serving the Flat Iron Steak
After removing the steak from the oven, let it rest for 5 to 10 minutes before slicing. Resting allows the juices to redistribute within the meat, resulting in a juicier, more flavorful steak. Cover the steak loosely with aluminum foil to retain warmth during this period.
When slicing, cut against the grain to maximize tenderness. The flat iron steak’s muscle fibers run lengthwise, so cutting perpendicular to the grain shortens the fibers and makes chewing easier.
For serving, consider pairing the steak with complementary sauces such as chimichurri, peppercorn cream, or a simple garlic butter. Accompany the dish with sides like roasted vegetables, mashed potatoes, or a fresh salad for a balanced meal.
Additional Tips for Oven Cooking Flat Iron Steak
- Use an oven-safe thermometer probe if possible to monitor temperature without opening the oven door.
- Avoid overcrowding the pan during searing to maintain high heat and proper crust formation.
- If you do not have an oven-safe skillet, transfer the steak to a preheated baking sheet after searing.
- Baste the steak with melted butter and herbs during resting for enhanced flavor.
- For thicker cuts, consider finishing the steak under the broiler for 1-2 minutes to achieve a crispier crust.
Preparing Flat Iron Steak for Oven Cooking
Proper preparation is crucial for achieving a tender and flavorful flat iron steak when cooking it in the oven. Begin by selecting a high-quality flat iron steak, ideally well-marbled and about 1 to 1.5 inches thick to ensure even cooking.
- Bring steak to room temperature: Remove the steak from the refrigerator at least 30 minutes before cooking. This allows for more even heat distribution during cooking.
- Pat dry: Use paper towels to remove excess moisture from the steak’s surface. A dry surface promotes better browning and crust formation.
- Seasoning: Generously season both sides with kosher salt and freshly ground black pepper. Optionally, add garlic powder, smoked paprika, or your preferred steak seasoning blend for enhanced flavor.
- Optional marinating: For additional tenderness and flavor, marinate the steak for 1 to 4 hours in a mixture containing acidic components like balsamic vinegar, citrus juice, or wine, combined with herbs and oil.
Searing the Flat Iron Steak Before Oven Roasting
Searing the steak before placing it in the oven is essential to develop a rich, caramelized crust. This step locks in juices and enhances the steak’s overall taste and texture.
- Preheat a heavy, oven-safe skillet (preferably cast iron) over medium-high heat until very hot.
- Add a small amount of high smoke point oil, such as canola, grapeseed, or avocado oil, to the skillet.
- Place the steak in the skillet without crowding. Sear each side for about 2-3 minutes until a deep brown crust forms.
- Don’t forget to sear the edges by holding the steak with tongs to ensure uniform browning.
Oven Cooking Method and Temperature Guidelines
After searing, transfer the skillet with the steak directly into a preheated oven. The oven cooking step finishes the steak gently, allowing for precise control over doneness.
| Oven Temperature | Internal Temperature Target | Approximate Oven Time | Steak Doneness |
|---|---|---|---|
| 400°F (204°C) | 125°F (52°C) | 6-8 minutes | Rare |
| 400°F (204°C) | 130-135°F (54-57°C) | 8-10 minutes | Medium Rare |
| 400°F (204°C) | 140-145°F (60-63°C) | 10-12 minutes | Medium |
| 400°F (204°C) | 150-155°F (65-68°C) | 12-15 minutes | Medium Well |
