Pan Seared Porterhouse Steak

My pan-seared porterhouse steak recipe brings out the best from this premium cut: its rich flavor, tenderness, and juiciness. But this recipe is more than just a set of instructions. It’s also a guide that delves into why I’ve chosen this particular method for pan-searing the porterhouse.

The porterhouse steak, while delicious, is one of the more complicated steaks to cook in a pan. What makes it particularly tricky is its dual nature, featuring two distinct cuts of beef (new york strip and filet mignon) separated by a bone. However, this recipe is easier than you think. Follow the instructions below, and you’ll love the results.

The Ingredients You’ll Need

To prepare a delicious porterhouse steak infused with an herb-butter flavor using a skillet, you’ll need just a handful of well-known ingredients:

  • A 1.5 to 2 inches thick porterhouse steak
  • High-smoke point oil (I recommend avocado oil)
  • Kosher salt
  • Finely ground pepper
  • Unsalted butter
  • Garlic cloves
  • Fresh Thyme or Rosemary

The Tools You’ll Need

  • Cast Iron Skillet
  • Tongs
  • Instant Read Thermometer

How to Cook Porterhouse Steak on a Stove

Here is the step-by-step guide for preparing the perfect porterhouse steak in a skillet on a stove. Please don’t skip any details, as I offer numerous valuable tips. If you’re new to pan-searing steaks, I recommend studying the instructions multiple times to ensure a smooth cooking experience.

Note: When buying a porterhouse steak, choose one between 1.5 and 2 inches thick. I’ve chosen a steak that’s 1.5 inches thick for this recipe. Why is this so important? A steak with the right thickness is the key to achieving the perfect balance between the interior and exterior of the steak – especially if you prefer medium-rare doneness.

Step 1: Prepare the Porterhouse Steak

The preparation of the steak varies depending on when you plan to cook it and the specific result you’re aiming for. Here are three options to consider:

  • Option 1 (Not recommended): If you’re in a hurry and want to cook the steak immediately, remove it from the refrigerator and allow it to sit at room temperature for 20-30 minutes, then move to the next step.
  • Option 2 (For a better flavor and crust): Remove the steak from the refrigerator, season it generously on all sides with salt, and let it rest on a rack for at least 40-50 minutes. After the resting period, you’re ready for step 2.
  • Option 3 (Highly Recommended): For the best results, generously salt the steak on all sides and place it on a rack in the refrigerator for 24 hours. When you’re ready to cook the next day, take the steak out and let it sit at room temperature for about 30 minutes. Move on to step 2 afterward. You’ll notice that the steak’s surface is drier 24 hours post-salting, making it ideal for pan-searing.

Important advice: Avoid searing a steak between 10 to 40 minutes after salting. Achieving the best crust requires the steak’s surface to be as dry as possible. In the window between 10 to 40 minutes post-salting, the salt draws out significant moisture from the steak, which can compromise your crust.

Step 2: Preheat the Cast-Iron Skillet

To achieve the best results, ensure the pan reaches a temperature of at least 450°F. Preheat a thick pan, ideally a cast-iron skillet, on high heat for 3-4 minutes. While it’s heating up, season your steak with pepper and garlic.

Note: It’s best to use very finely ground seasonings. This ensures the steak maintains maximum contact with the skillet’s surface during cooking.

After the skillet has been preheated for 3-4 minutes, add one tablespoon of oil with a high smoke point. Wait for a minute, then move on to the third step.

Note: I recommend using avocado oil. Not only does it have a smoke point of about 510°F, but it also offers a neutral flavor.

Step 3: Place the Porterhouse Steak in the Skillet

Carefully place the steak in the skillet. Keep in mind both the oil and pan are extremely hot. Gently press the steak to ensure maximum contact with the skillet’s surface. When you do this, expect a sizzle and a fair amount of smoke – this is completely normal.

Sear the steak, flipping it every 1-2 minutes until a thermometer reads an internal temperature of approximately 100°F. Then, reduce the heat to low and add the crushed garlic clove, rosemary (or thyme), and butter to the pan. Allow the butter to melt. 

While the butter is melting, take the opportunity to sear the steak’s sides quickly.

Note: In my experience, it took roughly 5-7 minutes to cook a 1.5-inch thick porterhouse steak to reach an internal temperature of 100°F. However, various factors can influence the cooking time, so your experience might differ. Always use a reliable instant-read thermometer for monitoring your steak’s temperature. If you don’t own one, consider purchasing; it’s a worthwhile investment.

Step 4: Baste the Porterhouse Steak with Butter

Tilt the pan to collect the melted butter, lightly seared garlic, and herbs at its bottom edge. Then, baste the steak with the butter consistently for 30 to 60 seconds on each side using a spoon. Afterward, check the steak’s temperature and continue cooking until it’s 15°F to 20°F below your desired doneness, and then remove it from the pan.

Note: I aimed for medium-rare for this recipe, so I took the steak out at approximately 115°F. Remember that the steak’s temperature will rise by as much as 15-20°F due to carryover cooking once removed from the pan. That’s why removing the steak at the right moment and allowing it to rest is crucial.

Step 5: Let the Porterhouse Steak Rest

Place the steak on a cutting board or, ideally, on a rack that allows airflow around the entire steak. Let it rest for 5-10 minutes (depending on thickness). Five minutes is the generally accepted minimum.

Note: Allowing the steak to rest isn’t just about the temperature. If you slice the steak immediately after cooking, it will release a significant amount of its juices. Instead, letting it rest for 5 to 10 minutes will enable the steak’s muscles to relax and the juices to redistribute. As a result, when you finally cut the steak, juice loss will be minimal.

How long does it take to sear strip steak on the stove?

For my 1.5-inch thick porterhouse steak, I seared it on the stove for about 7-10 minutes to achieve medium-rare doneness, maintaining the skillet’s temperature at around 450-500°F. However, remember that the searing duration for a porterhouse steak can vary based on its thickness, your desired level of doneness, and the skillet’s temperature.

Also, remember the times provided here are merely guidelines. It’s always best to rely on thermometer readings and to approach any suggested cooking times with caution to ensure a perfectly cooked steak every time.

Is porterhouse steak better pan-seared or grilled?

Both pan-searing and grilling offer fantastic flavors, but I strongly prefer grilling a porterhouse over pan-searing for even cooking and crust formation.

The tenderloin section of the porterhouse cooks faster than the strip section because the filet mignon is leaner. This makes evenly cooking an entire porterhouse steak in a pan challenging. Additionally, the bone often creates a barrier, preventing the two sections from fully contacting the pan’s surface and affecting the crust formation. One might suggest weighing the steak down as a solution, but not everyone has the necessary tools in their kitchen for this task. On the grill, it’s a different story.

Grilling provides the flexibility to adjust the heat, allowing both the strip and tenderloin sections to reach similar internal temperatures. This adaptability is a primary reason many, including me, believe the porterhouse shines brightest on the grill. Moreover, the grill excels in producing a crust that’s challenging to replicate in a pan.
