If you’ve ever wondered how to cook a porterhouse steak that’s juicy, tender, and bursting with flavor, you’re in the right place. This iconic cut, combining both the tenderloin and the New York strip separated by a T-shaped bone, is a steak lover’s dream. It’s large, impressive, and perfect for sharing – but it does require some know-how to get it just right. Let’s dive into the best ways to cook a porterhouse steak, step-by-step, so you can enjoy steakhouse-quality results at home.
What Is a Porterhouse Steak?
A porterhouse steak is a large, premium cut from the short loin of the cow. It includes two distinct steaks in one: the tender filet mignon on one side of the bone and the flavorful New York strip on the other. To qualify as a porterhouse, the tenderloin portion must be at least 1¼ inches thick, distinguishing it from the smaller T-bone steak.
This cut often weighs around two pounds or more, making it ideal for two or more people. Its size and combination of textures make it a favorite for special occasions and steak dinners.
Preparing Your Porterhouse Steak
1. Bring to Room Temperature
Take your steak out of the refrigerator about 30 to 45 minutes before cooking. This step ensures even cooking and better control over doneness.
2. Season Generously
Pat the steak dry with paper towels. Then, season both sides liberally with salt and freshly ground black pepper. This helps form a beautiful crust when searing. You can also add minced garlic and fresh rosemary for extra flavor if you like.
How to Cook a Porterhouse Steak
There are several popular methods to cook a porterhouse steak, each delivering a delicious result. Here are the most effective:
Grilling
Grilling is the classic way to cook porterhouse steak and gives it that authentic steakhouse flavor.
– Preheat your grill to high heat (around 450°F).
– Brush the steak with olive oil and season again lightly.
– Place the steak on the hottest part of the grill and sear for about 2-3 minutes per side to develop a deep brown crust.
– For medium-rare, grill for about 4-5 minutes per side, adjusting time based on thickness.
– Use a two-zone fire if possible: sear on the hot side, then move to indirect heat to finish cooking without burning.
– Let the steak rest for 10 minutes before slicing.
Pan-Searing with Oven Finish
This method is great for indoor cooking and guarantees a juicy interior with a crisp crust.
– Preheat your oven to 400°F.
– Heat a cast-iron skillet over medium-high heat with a tablespoon or two of oil until just smoking.
– Sear the porterhouse steak for 2-3 minutes on each side without moving it to get a good crust.
– Transfer the skillet to the oven and roast:
– Rare: 4 minutes
– Medium-rare: 5-6 minutes
– Medium: 6-7 minutes
– Remove from oven and rest the steak for 5-10 minutes before serving.
Pan-Roasting with Butter and Aromatics
For added flavor, after searing, you can baste the steak with butter, garlic, and herbs like rosemary or thyme.
– After searing both sides, add butter, crushed garlic cloves, and fresh herbs to the pan.
– Tilt the pan and spoon the melted butter over the steak repeatedly for 1-2 minutes.
– Finish in the oven if needed to reach desired doneness.
Checking Doneness: Temperature Guide
Using a meat thermometer is the best way to ensure your porterhouse steak is cooked perfectly:
| Doneness | Internal Temperature (°F) |
|---|---|
| Rare | 120-125 |
| Medium-Rare | 130-134 |
| Medium | 135-144 |
| Medium-Well | 145-155 |
Remember, the steak will continue to cook slightly after resting, so remove it from heat a few degrees before your target temperature.
Resting and Serving
Resting your steak is crucial. After cooking, tent it loosely with foil and let it rest for about 10 minutes. This allows the juices to redistribute, resulting in a moist and tender steak.
When ready to serve:
– Cut the steak off the bone carefully.
– Slice against the grain into thin strips for maximum tenderness.
– Serve with your favorite sides, sauces, or a simple pat of butter on top.
Tips for the Best Porterhouse Steak
– Don’t rush the sear: A good crust locks in flavor and juices.
– Use a cast-iron skillet: It retains heat well and helps develop a perfect crust.
– Season well: Salt is your friend for flavor and crust formation.
– Let it rest: Never skip resting; it makes all the difference.
– Choose quality meat: A well-marbled porterhouse will cook better and taste richer.
Enjoy your porterhouse steak with classic sides like garlic mashed potatoes, grilled vegetables, or a fresh chimichurri sauce for a delicious meal that impresses every time.
A perfectly cooked porterhouse steak is a celebration of beef’s best qualities-rich flavor, tender texture, and a satisfying bite. With these simple steps, you’ll master cooking this impressive cut and enjoy steakhouse quality right at home.
