LongHorn Porterhouse Signature Porterhouse Steak
The LongHorn Porterhouse is cut from the short loin primal, the same section that produces the New York Strip and T-Bone giving you two completely different steaks separated by one bone. Every cut is made from USDA Choice beef, fresh and never frozen, cooked on the open-flame char grill by certified Grill Masters at LongHorn Steakhouse.
The Cut Two Premium Steaks, One Bone
The T-shaped bone divides the steak into two completely different eating experiences on one plate. On the larger side sits the New York Strip firm, bold, and packed with assertive beef flavor. On the smaller side sits a large Filet Mignon delicate, buttery, and melt in your mouth tender. The Porterhouse is cut further back along the short loin where the tenderloin muscle is larger than T-Bone giving you more strip, more filet, and more steak on a single plate.
Why Bone In Steaks Taste Better at LongHorn
The bone insulates the meat during cooking, distributing heat more evenly and preventing the edges from overcooking. Fat and marrow near the bone also release rich flavor compounds into the surrounding meat as it grills. Every LongHorn Porterhouse goes on the open-flame char grill the same setup used for the Outlaw Ribeye and Fire-Grilled T-Bone where the Maillard reaction builds a proper caramelized, smoky crust that no flat-top grill can replicate.

Cooking Temperatures for LongHorn Porterhouse
The LongHorn Porterhouse is the most technically complex steak to order correctly because the strip side and the filet side have different ideal temperatures. Always order based on the filet side, which is more delicate and loses quality faster when overcooked
| Doneness | Internal Temp | Strip Side | Filet Side | Recommended? |
|---|---|---|---|---|
| Rare | 120–125°F | Cool red, fat not rendering | Cool red, very soft | Not recommended |
| Medium Rare | 130–135°F | Warm red, marbling melting | Warm red, buttery tender | ⭐ Best Choice |
| Medium | 140–145°F | Pink, juicy, firm | Pink, still tender | ⭐ Great Choice |
| Medium Well | 150–155°F | Slight pink, firmer | Noticeably firmer | Acceptable |
| Well Done | 160°F+ | No pink, tough | Dry, loses all tenderness | Not recommended |
Why Medium Rare Is Best for Porterhouse
For the LongHorn Porterhouse, Medium Rare (130-135°F) hits both sides at their sweet spot simultaneously. The strip side needs heat to render its marbling for a bold, juicy bite. The filet side needs to stay pink to preserve its buttery tenderness. Let the filet dictate your temperature every time every certified LongHorn Grill Master is trained under the Legendary Grill training program specifically to balance this challenge.
