Why Flat Iron Steak?

The flat iron steak is cut from the shoulder of the cow, specifically the chuck. It’s the second most tender cut after the tenderloin and boasts excellent marbling, which contributes to its juicy and flavorful profile. Unlike some other cuts, the flat iron is relatively thin and cooks quickly, making it ideal for a weeknight dinner. It’s also a more affordable option than premium cuts like ribeye or filet mignon, without sacrificing much in terms of taste or texture.

The Magic of Balsamic Reduction

The balsamic reduction, also known as balsamic glaze, is a concentrated and intensely flavored sauce made by simmering balsamic vinegar until it thickens and its flavors become more pronounced. The process mellows the vinegar’s acidity and intensifies its sweetness, resulting in a syrupy glaze that’s perfect for drizzling over grilled meats, vegetables, or even desserts. The combination of the savory steak and the sweet-tart balsamic reduction is a match made in culinary heaven.

Ingredients You’ll Need

* **Flat Iron Steaks:** 2 (6-8 ounces each), about 1 inch thick
* **Balsamic Vinegar:** 1 cup
* **Olive Oil:** 2 tablespoons, plus more for drizzling
* **Garlic:** 2 cloves, minced
* **Fresh Thyme:** 2 sprigs
* **Salt:** Kosher salt or sea salt
* **Black Pepper:** Freshly ground
* **Optional:** 1 tablespoon honey or maple syrup (for extra sweetness in the reduction)

Equipment You’ll Need

* **Cast Iron Skillet or Grill Pan:** A cast iron skillet provides excellent heat retention and searing capabilities. A grill pan is a good alternative if you prefer grill marks.
* **Small Saucepan:** For making the balsamic reduction.
* **Tongs:** For flipping the steak.
* **Meat Thermometer:** To ensure the steak is cooked to your desired doneness.
* **Cutting Board:** For resting and slicing the steak.

Step-by-Step Instructions: Perfect Flat Iron Steak with Balsamic Reduction

Step 1: Prepare the Balsamic Reduction

This reduction takes time, so start it first.

1. **Combine Ingredients:** In a small saucepan, pour the balsamic vinegar. If desired, add 1 tablespoon of honey or maple syrup for extra sweetness. Adding honey or maple syrup is optional; it depends on the quality and sweetness of your balsamic vinegar.
2. **Simmer:** Bring the balsamic vinegar to a gentle simmer over medium-low heat. Reduce the heat to low and let it simmer uncovered. It’s crucial to maintain a gentle simmer to prevent burning.
3. **Reduce:** Allow the balsamic vinegar to reduce for about 20-30 minutes, or until it has thickened to a syrupy consistency. Stir occasionally to prevent sticking. The reduction is ready when it coats the back of a spoon. Be patient, as the timing can vary depending on your stove and the vinegar’s acidity. The volume will reduce significantly, usually to about ¼ cup.
4. **Cool:** Once the reduction is ready, remove it from the heat and let it cool slightly. It will thicken further as it cools.

Step 2: Prepare the Steak

1. **Bring to Room Temperature:** Remove the flat iron steaks from the refrigerator at least 30 minutes before cooking. This allows the steaks to cook more evenly. Pat the steaks dry with paper towels. Removing excess moisture will help achieve a good sear.
2. **Season Generously:** Season both sides of the steaks liberally with salt and freshly ground black pepper. Don’t be shy with the seasoning! The salt will help create a beautiful crust and enhance the flavor of the steak. You can also add other seasonings like garlic powder, onion powder, or paprika for extra flavor, if desired.

Step 3: Cook the Steak

There are two primary methods for cooking flat iron steak: searing in a skillet or grilling. We’ll cover both.

Method 1: Searing in a Cast Iron Skillet

1. **Heat the Skillet:** Place a cast iron skillet over high heat. Allow the skillet to get screaming hot. This is essential for achieving a good sear.
2. **Add Oil:** Once the skillet is hot, add 2 tablespoons of olive oil. The oil should shimmer and just begin to smoke.
3. **Sear the Steak:** Carefully place the steaks in the hot skillet, ensuring they are not overcrowded. Sear the steaks for 3-4 minutes per side for medium-rare, or longer depending on your desired doneness. Avoid moving the steaks around during the searing process to allow a crust to form. Use tongs to flip the steaks.
4. **Add Aromatics (Optional):** During the last minute of cooking, add the minced garlic and thyme sprigs to the skillet. Spoon the hot oil over the steaks to infuse them with the garlic and thyme flavors. Be careful not to burn the garlic.
5. **Check for Doneness:** Use a meat thermometer to check the internal temperature of the steak. Insert the thermometer into the thickest part of the steak, avoiding any bone. Here are the recommended internal temperatures for different levels of doneness:
* **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+)
6. **Rest:** Once the steaks have reached your desired doneness, remove them from the skillet and place them on a cutting board. Tent them loosely with foil and let them rest for at least 10 minutes. Resting allows the juices to redistribute throughout the steak, resulting in a more tender and flavorful final product. Skipping this step will result in the juices running out when you slice the steak, leaving you with a drier piece of meat.

Method 2: Grilling

1. **Prepare the Grill:** Preheat your grill to high heat. Make sure the grates are clean and lightly oiled to prevent sticking. You can use a gas grill or a charcoal grill.
2. **Grill the Steak:** Place the seasoned steaks on the hot grill grates. Grill for 3-4 minutes per side for medium-rare, or longer depending on your desired doneness. Rotate the steaks 45 degrees halfway through each side to create beautiful grill marks.
3. **Check for Doneness:** Use a meat thermometer to check the internal temperature of the steak, following the same temperature guidelines as for skillet cooking.
4. **Rest:** Once the steaks have reached your desired doneness, remove them from the grill and place them on a cutting board. Tent them loosely with foil and let them rest for at least 10 minutes.

Step 4: Slice and Serve

1. **Slice Against the Grain:** After the steaks have rested, use a sharp knife to slice them against the grain. Slicing against the grain shortens the muscle fibers, making the steak more tender and easier to chew. The grain of the flat iron steak runs lengthwise, so slice perpendicular to the long side of the steak.
2. **Drizzle with Balsamic Reduction:** Arrange the sliced steak on a serving platter and drizzle generously with the balsamic reduction. You can also drizzle a little extra olive oil over the steak for added richness.
3. **Garnish (Optional):** Garnish with fresh herbs such as thyme, rosemary, or parsley for a pop of color and flavor. A sprinkle of flaky sea salt can also enhance the flavor.

Tips for Success

* **Choose High-Quality Steak:** Look for flat iron steaks with good marbling, which indicates more flavor and tenderness. Grass-fed beef will have a different flavor profile than grain-fed beef. Choose the type that you prefer.
* **Don’t Overcook:** Flat iron steak is best served medium-rare to medium. Overcooking will make it tough and dry. Use a meat thermometer to ensure accurate doneness.
* **Let it Rest:** Resting the steak after cooking is crucial for retaining its juices and ensuring a tender final product.
* **Adjust Seasoning:** Taste the balsamic reduction and adjust the seasoning as needed. If it’s too tart, add a little more honey or maple syrup. If it’s too sweet, add a squeeze of lemon juice.
* **Use a Hot Pan or Grill:** A hot cooking surface is essential for achieving a good sear and flavorful crust.
* **Slice Thinly:** Slicing the steak thinly against the grain will make it easier to chew and more enjoyable to eat.
* **Consider a Marinade:** For even more flavor, marinate the flat iron steak for a few hours before cooking. A simple marinade can consist of olive oil, balsamic vinegar, garlic, herbs, and seasonings.

Serving Suggestions

Flat iron steak with balsamic reduction is a versatile dish that can be served with a variety of sides. Here are a few suggestions:

* **Roasted Vegetables:** Asparagus, Brussels sprouts, carrots, potatoes, or bell peppers all pair well with the steak.
* **Mashed Potatoes or Sweet Potatoes:** Creamy mashed potatoes or roasted sweet potatoes provide a comforting and satisfying side dish.
* **Salad:** A fresh green salad with a light vinaigrette provides a refreshing contrast to the richness of the steak.
* **Quinoa or Rice:** These grains offer a healthy and filling side dish.
* **Grilled Corn on the Cob:** A classic summer side dish that complements the grilled steak perfectly.
