Instructions 👩‍🍳

Step-by-step:

Prepare the porterhouse: Pat the steak dry and season the surfaces with salt and pepper. Keep the strip and tenderloin sections attached to the bone for grilling. The exact details are shown in the illustrated recipe.
Prepare the grill zones: Set up direct and indirect grilling areas. Position the smaller tenderloin section so it is less exposed to the strongest heat.
Sear and finish: Brown the steak on both sides, then move it to the indirect area. Check both meat sections with a thermometer without touching the bone and finish according to the recipe guidance.
Rest and carve: Rest the steak before carving. Cut the strip and tenderloin away from the bone, slice each across the grain and arrange together for serving.

Porterhouse steak: two cuts to enjoy from one grill

A porterhouse gives you two cuts to compare on one plate: strip steak and tenderloin, separated by a T-shaped bone. This grilled version uses simple seasoning, a hot sear and an indirect finish. Keep both sections in mind as it cooks, then serve their slices separately so you can enjoy the difference for yourself.

Strip, tenderloin and a little seasoning

The porterhouse comes from the beef loin and has a larger tenderloin portion than a T-bone steak in the US cutting system. Coarse sea salt and black pepper are the base seasonings here. Look at the two muscle sections when choosing your steak; each needs attention during cooking.

Use the sear for browning and the thermometer for the center

A dry surface helps the steak brown. Direct heat means the meat is over the heat source; the indirect finish moves it away from that concentrated heat while it continues cooking. Check the thickest part of both the strip and tenderloin with a food thermometer, avoiding bone and fat. One reading cannot describe both sections.

USDA safety guidance for beef steaks is at least 145°F before removal from the heat and at least 3 minutes of rest afterward. A brown crust, pink center or fixed cooking time is not a safety test. Keep raw meat chilled until preparation, do not rinse it, and keep it separate from ready-to-eat foods. Use clean utensils and a clean plate after cooking. Refrigerate leftovers promptly in a shallow container.

Keep the two cuts recognizable

After the steak has rested, separate the strip and tenderloin from the bone and slice each across its muscle fibers. Arrange the sections separately on a clean platter. Potatoes, mushrooms or a green salad leave plenty of room for the steak. If you want to focus on the strip portion alone, the New York strip is a useful next choice.

Plan for both sides of the bone

Before grilling, identify the strip and tenderloin so you know where to take each temperature reading.
Keep an indirect area available for the finishing stage rather than relying on the searing area throughout.
Look for the direction of the fibers in each section before slicing; they do not need to be cut at the same angle on the board.

Optional seasoning variations

The preparation also allows a steak rub instead of the simple salt-and-pepper seasoning. Check whether the blend already contains salt before adding more. Garlic or herbs offer another optional flavor direction; choose a combination you enjoy without covering the steak in several competing seasonings.

Store raw meat and cooked portions safely

Keep raw porterhouse refrigerated in a leakproof container, separate from food that is ready to eat, and follow the package’s storage and use-by instructions. Refrigerate cooked leftovers promptly in a clean, shallow container. Keeping the strip and tenderloin portions separate also makes it easier to choose what you want to serve later.

Frequently asked questions

How is a porterhouse different from a T-bone?
Both combine strip and tenderloin around a T-shaped bone. In the US cutting system, the porterhouse has the larger tenderloin portion.

Why check both parts with a thermometer?
They are distinct sections that may cook differently. Measure the thickest part of each without touching the bone, rather than assuming one reading represents the whole steak.

Can I judge doneness from the crust?
No. Browning shows what has happened at the surface. Safe cooking needs a thermometer check inside the meat and the appropriate rest afterward.

Does it need to become warm throughout before grilling?
Do not leave raw porterhouse out waiting for the center to reach room temperature. Keep preparation brief and refrigerate it again if cooking is delayed.
