How To Cook Porterhouse Steak

Introduction

The porterhouse steak, a king among cuts, is renowned for its generous size and the unique combination of tenderloin and strip steak separated by a T-bone. Learning how to cook porterhouse steak properly unlocks a world of culinary satisfaction. Its popularity stems from the contrasting textures and flavors offered in a single steak, making it a favorite for special occasions and upscale dining. The porterhouse is commonly cooked because it lends itself well to various cooking methods, each capable of producing a delicious and memorable meal.

Ingredients

The foundation of a great porterhouse starts with quality ingredients.

Porterhouse Steak: Approximately 1.5 – 2 inches thick. Look for good marbling throughout the meat.
Kosher Salt: Enhances the natural flavors of the beef.
Freshly Ground Black Pepper: Adds a subtle spice and depth.
High-Heat Cooking Oil: Such as avocado oil, grapeseed oil, or clarified butter (ghee).
Optional: Fresh garlic cloves, fresh thyme or rosemary sprigs, butter (for basting).

Preparation Steps

Proper preparation is crucial for even cooking and maximum flavor.

Pat Dry: Use paper towels to thoroughly pat the porterhouse steak dry. This promotes a good sear.
Season Generously: Liberally season both sides of the steak with kosher salt and freshly ground black pepper. Don’t be shy; the thick cut can handle a generous amount.
Rest at Room Temperature: Allow the steak to sit at room temperature for at least 30 minutes, and up to an hour, before cooking. This helps the steak cook more evenly.
Optional: For added flavor, consider a dry brine by seasoning the steak with salt 1-2 hours before cooking and leaving it uncovered in the refrigerator.

Tip: The dry surface is key to achieving a beautiful crust. Avoid adding oil before searing; the steak’s own fat will render and contribute to the searing process.

Cooking Instructions

There are several methods to cook a porterhouse steak to perfection. Here are two popular options: pan-searing followed by oven-finishing, and grilling. Method 1: Pan-Sear and Oven Finish

Preheat Oven: Preheat the oven to 400F (200C).
Sear: Heat a heavy-bottomed skillet (cast iron is ideal) over high heat until it’s smoking hot. Add high-heat cooking oil.
Sear the Steak: Carefully place the porterhouse steak in the hot skillet. Sear for 2-3 minutes per side, creating a deep brown crust.
Add Aromatics (Optional): Add crushed garlic cloves, thyme, or rosemary sprigs to the pan during the last minute of searing for added flavor.
Baste (Optional): If desired, add a knob of butter to the pan and baste the steak with the melted butter, garlic, and herbs for extra richness.
Transfer to Oven: Transfer the skillet to the preheated oven.
Oven Finish: Cook to your desired doneness (see recommended times below).
Rest: Remove the steak from the oven and let it rest for at least 10 minutes before slicing.

Method 2: Grilling

Prepare Grill: Preheat the grill to high heat. Ensure the grill grates are clean and oiled.
Sear: Place the porterhouse steak on the hottest part of the grill and sear for 3-4 minutes per side, creating distinct grill marks.
Move to Indirect Heat: Move the steak to a cooler part of the grill (indirect heat) to finish cooking.
Grill to Desired Doneness: Grill until the internal temperature reaches your desired level (see recommended times below).
Rest: Remove the steak from the grill and let it rest for at least 10 minutes before slicing.

Recommended Internal Temperatures and Cooking Times (Pan-Sear/Oven Finish and Grill):

Rare: 125-130F (52-54C) – Approximately 4-6 minutes in the oven after searing (for a 1.5-2 inch steak).
Medium-Rare: 130-135F (54-57C) – Approximately 6-8 minutes in the oven after searing.
Medium: 135-145F (57-63C) – Approximately 8-10 minutes in the oven after searing.
Medium-Well: 145-155F (63-68C) – Approximately 10-12 minutes in the oven after searing.
Well-Done: 155F+ (68C+) – Not recommended, as the steak will become tough.

Note: Use a meat thermometer to accurately gauge the internal temperature. Cooking times are approximate and may vary depending on the thickness of the steak and the accuracy of your oven/grill.

Serving Suggestions

A porterhouse steak is impressive on its own, but these serving suggestions elevate the experience:

Classic: Serve with a simple pan sauce made from deglazing the pan with red wine or beef broth after cooking.
Sides: Pair with classic steakhouse sides such as mashed potatoes, roasted asparagus, creamed spinach, or a loaded baked potato.
Garnishes: Garnish with fresh herbs like parsley or chives, a pat of compound butter (herb or garlic infused), or a sprinkle of sea salt flakes.
Plating: Slice the steak against the grain and arrange the slices artfully on a platter or individual plates.

Tips and Common Mistakes

Avoid these common mistakes and follow these tips for a perfect porterhouse:

Don’t overcrowd the pan: Ensure the steak has enough space in the pan to sear properly. Overcrowding lowers the temperature and results in steaming, not searing.
Don’t flip too early: Allow the steak to develop a good crust before flipping.
Use a meat thermometer: Don’t rely on guesswork to determine doneness. A meat thermometer is essential for accurate cooking.
Rest the steak: Resting allows the juices to redistribute, resulting in a more tender and flavorful steak. Don’t skip this step!
Slicing against the grain: This shortens the muscle fibers, making the steak easier to chew.
Salting too late: Always season generously with salt well in advance of cooking (at least 30 minutes) to allow the salt to penetrate the meat.
