There’s nothing quite like cooking a juicy and flavorful porterhouse steak in a cast iron skillet. The heat retention and distribution of the skillet ensures a perfect sear on your steak, creating a delicious crust that locks in the juices for a mouth-watering finish. In this article, I’ll walk you through the steps to cook the best porterhouse steak in a cast iron skillet, from choosing the right cut to letting it rest before serving.

Key Takeaways:

  • Using a cast iron skillet is the perfect way to cook a porterhouse steak.
  • Choosing the right cut of steak is crucial to achieving a beautifully cooked steak.
  • Proper preparation and cooking techniques are essential for a juicy and flavorful outcome.

Choosing the Right Porterhouse Steak

When it comes to cooking a perfect Porterhouse steak, selecting the right cut of meat is crucial. You want to choose a steak that is well-marbled with fat and has a bright, vibrant red color. Look for a thick cut that is at least 1 1/2 inches in thickness to ensure a juicy, tender steak.

It’s also essential to consider the quality of the meat. Choosing grass-fed, organic beef from a reputable source ensures that your steak is high in nutrients and free from harmful chemicals and additives.

Another crucial factor is the aging of the steak. Dry-aged Porterhouse steak is known for its intense flavor and tenderness. Dry-aging allows the enzymes in the meat to break down the muscle fibers, resulting in a more tender steak with a concentrated flavor.

Ultimately, the best way to cook a Porterhouse steak is to choose the highest quality cut you can afford and prepare it with care. Whether you prefer a dry-aged or fresh steak, a well-marbled thick cut is key to achieving a perfectly cooked Porterhouse steak.

Preparing the Porterhouse Steak

Before cooking the steak, it is essential to bring it to room temperature. I usually leave it on the kitchen counter for about an hour before I start cooking. This ensures even cooking throughout the steak.

Next, I use a paper towel to pat the steak dry. Moisture on the surface of the steak can cause it to steam instead of sear, resulting in a less crispy crust.

Then, I generously season the steak with salt and pepper on both sides. Don’t be afraid to use more than you think is necessary – the seasoning is what gives the steak its flavor.

Now it’s time to prepare the cast iron skillet. I heat it over high heat until it’s smoking hot. Then, I add a small amount of oil to the pan. I prefer to use an oil with a high smoke point, such as canola or vegetable oil. Once the oil starts to shimmer, it’s time to sear the steak.

How to Sear a Porterhouse Steak in a Cast Iron Skillet

To get that perfect sear on your steak, follow these steps:

  1. Carefully place the steak in the hot skillet. Make sure it sizzles when it hits the pan.
  2. Let the steak cook undisturbed for about 3-4 minutes. This allows a crust to form on the bottom of the steak.
  3. Flip the steak over and cook for another 3-4 minutes. You can use tongs to check the steak’s doneness. A rare steak will feel soft when you press it with your tongs, medium-rare will be a bit firmer, and medium will feel quite firm.
  4. If you want your steak more well-done, you can continue cooking it for another 2-3 minutes per side.

Once you’ve seared the steak, it’s time to move on to the next step: cooking it to your desired level of doneness.

Cooking the Porterhouse Steak

After preparing the Porterhouse steak, it’s time to cook it to juicy perfection in the cast iron skillet. Follow this Cast Iron Skillet steak recipe for a delicious and mouthwatering steak dinner.

Heat the cast iron skillet over high heat until it’s smoking hot, about five minutes. Meanwhile, season the steak generously with salt and pepper on both sides.

Steak Thickness Cooking Time
1 inch 4-5 minutes per side
1.5 inches 5-6 minutes per side
2 inches 6-7 minutes per side

When the skillet is ready, add a tablespoon of oil and carefully place the steak in the skillet. Cook the steak for the recommended time on each side, flipping it only once. Avoid moving the steak around as it cooks to ensure a good sear.

To achieve the perfect Juicy Porterhouse Steak recipe, baste the steak with a tablespoon of butter and a sprig of fresh rosemary in the skillet during the last minute of cooking. This adds extra flavor and helps keep the steak juicy.

Remove the steak from the skillet and let it rest for 5-10 minutes, tented with foil. This helps the juices to redistribute through the steak and results in a tender and juicy steak.

Serve the Porterhouse steak with your favorite sides and enjoy!

Letting the Steak Rest and Serving

Once the porterhouse steak is cooked to your desired level of doneness, it’s important to let it rest for a few minutes before serving. This allows the juices to redistribute, resulting in a juicier and more flavorful steak.

To let the steak rest, remove it from the cast iron skillet and place it on a cutting board. Cover the steak with foil and let it rest for about 5 to 10 minutes. This will ensure that the steak is warm when served.

When cutting the porterhouse steak, make sure to cut against the grain to ensure tenderness. For best results, use a sharp knife and cut the steak into slices about 1/2 inch thick.

Serve the steak with your favorite sides, such as roasted vegetables or mashed potatoes. The porterhouse steak is a hearty meal that is perfect for special occasions or a weekend dinner with friends and family.
