Introduction
Imagine biting into a perfectly grilled steak, its juices cascading with every cut, the rich flavor enveloping your senses like a warm embrace. Among the various cuts of beef, few evoke such culinary reverence as the porterhouse steak. Yet, many home cooks and even avid steak enthusiasts often find themselves asking, "What part is a porterhouse steak?" Understanding this cut not only enhances your appreciation for it but also empowers you to cook it to perfection.
The porterhouse steak is a composite cut, famous for its generous size and the delightful combination of two different textures and flavors: the tenderloin and the New York strip. This cut hails from the back end of the short loin, where the muscle groups are less active, resulting in incredibly tender meat. However, the details of its anatomy and the nuances that separate it from similar cuts, like the T-bone steak, can be confusing.
By the end of this blog post, you will have a thorough understanding of what a porterhouse steak is, where it comes from, how it differs from other cuts, the best cooking methods, nutritional information, and of course, a few delicious recipe ideas to try at home. We’ll also touch on how Land and Sea Delivery’s premium selection can elevate your steak experience.
So, let’s dive into the world of this iconic steak cut and unveil the secrets behind its greatness.
The Anatomy of a Porterhouse Steak
What Is a Porterhouse Steak?
A porterhouse steak is a specific cut of beef that comes from the short loin section of the cow. It features a T-shaped bone that separates two distinct portions of meat: the larger New York strip on one side and the smaller tenderloin on the other. This unique configuration not only makes for a visually impressive steak but also provides a delightful contrast in texture and flavor.
The USDA has specific guidelines for what classifies a steak as a porterhouse. To qualify, the tenderloin portion must be at least 1.25 inches wide at its widest point. This is what sets it apart from the T-bone steak, which has a narrower tenderloin section of just 0.5 inches.

The Cut's Origins
The term "porterhouse" is believed to have originated in the early 19th century, with hints of its connection to the porterhouses (taverns) that served this hearty steak to patrons. Its rich flavor and substantial size made it a popular choice for hungry diners seeking a filling meal.
Historically, the porterhouse has been associated with fine dining and special occasions, often served at steakhouses renowned for their quality cuts. Both the tenderness of the meat and the flavor profile—characterized by its marbling—make it a coveted choice for steak lovers.
Where Does the Porterhouse Steak Come From?
The Short Loin Region
The porterhouse steak is specifically cut from the short loin section of the cow, located toward the back of the animal. This region contains some of the most tender muscles in the beef carcass, as these muscles do less work compared to other parts of the cow. The short loin area is also where you find other popular cuts, such as the T-bone steak, strip steak, and tenderloin.
Understanding the Separation
When a butcher prepares a porterhouse steak, they carefully slice through the vertebra to create the T-shaped bone that characterizes this cut. The larger, more generous portion of tenderloin distinguishes it from the T-bone steak, providing more of that buttery, melt-in-your-mouth texture that steak aficionados crave.
Cooking the Porterhouse Steak
Ideal Cooking Methods
Cooking a porterhouse steak can be an art form, and various methods can enhance its natural flavors. Here are the most popular cooking techniques:
-
Grilling: This is the go-to method for many steak lovers. The high heat creates a beautiful char on the outside while keeping the inside juicy and tender. Preheat your grill to high heat and cook the steak for about 4-5 minutes per side for medium-rare.
-
Pan-Seering: If grilling isn’t an option, a cast-iron skillet can work wonders. Sear the steak on high heat for a few minutes on each side, then transfer it to the oven to finish cooking.
-
Sous Vide: For precision cooking, sous vide allows you to maintain perfect temperature control. Cook the steak in a water bath at a set temperature (around 129°F for medium-rare) for a couple of hours, then finish with a quick sear on a hot grill or skillet.
Cooking Temperatures
To achieve the perfect porterhouse steak, it’s essential to monitor the internal temperature. Here’s a quick guide:
-
Rare: 120-130°F
-
Medium Rare: 130-140°F
-
Medium: 140-150°F
-
Medium Well: 150-160°F
-
Well Done: >160°F
Using a meat thermometer is highly recommended for accuracy. Remember to let the steak rest for 5-10 minutes after cooking to allow the juices to redistribute, ensuring a moist and flavorful bite.
