What Is the LongHorn®* Porterhouse?
The LongHorn® Porterhouse is one of the largest “Legendary Steaks” at LongHorn Steakhouse, described as a hefty 22 oz bone-in steak that combines two premium cuts in one: a tender filet and a hearty strip steak separated by a T-shaped bone. The steak is fire-grilled over high heat to produce a bold, smoky crust while keeping the inside juicy, and it is seasoned with LongHorn’s signature steak seasoning blend for an intense beefy flavor.
On the plate, this cut is designed for serious steak eaters or for sharing because of its size and rich fat content. It is typically served with choice of side(s) and may be ordered to the guest’s preferred doneness, just like other LongHorn steaks.

LongHorn®* Porterhouse Protein
For many guests, the main attraction of the LongHorn®* Porterhouse is the massive protein content.
Protein Content – LongHorn® Porterhouse
| Source | Protein Per Full Steak | Notes |
| LongHorn menu-info style site (22 oz listing) | 150 g | Listed with 1280 calories and 67 g fat. |
| Carb-tracking database (20 oz steak) | 126 g | With 74 g fat and 1250 calories. |
| Other nutrition entry (624 g portion) | ~50% of calories from protein | Works out near 150 g protein when calories are 1280. |
Even at the lower estimate of around 125 g, this is well over twice the daily protein target for many average adults, which explains why it is often recommended only for very hungry diners or people seeking a large post-training protein load.
LongHorn®* Porterhouse Allergen & Ingredient Info
LongHorn publishes allergen information through guides and PDFs, and third-party menu sites summarize common allergens, though the Porterhouse is primarily just seasoned beef cooked on shared equipment. Because restaurants can change recipes and cross-contact is possible, official documents always emphasize that allergen information is a guide, not an absolute guarantee.
General Ingredient and Allergen Notes – LongHorn® Porterhouse
| Aspect | Information (Approximate) | Notes |
| Main ingredient | Beef porterhouse steak | Bone-in combination of filet and strip. |
| Seasoning | House steak seasoning | Typically salt, pepper, spices, sometimes garlic/onion; exact blend proprietary. |
| Cooking fat | Grill oil or butter/steak finishing butter possible | Some locations brush steaks with butter or seasoned oil; may add dairy. |
| Gluten | Steak itself is naturally gluten-free; risk of cross-contact on grills or from sauces. | |
| Dairy | Risk if butter or butter-based finishing is used or if served with cheesy sides. | |
| Soy | Some guests with soy allergy report that staff can accommodate; shared surfaces still possible. | |
| Nuts | The steak itself does not typically contain nuts, but cross-contact in kitchen always possible. | |
| Egg / Shellfish | Not standard components of the steak, but may be present in some sides or shared fryers. |
Because allergen risk depends on local practices, anyone with serious allergies should ask for the latest official allergen guide and speak to staff before ordering.
Recommended Pairings for Porterhouse
The LongHorn® Porterhouse is rich, salty, and intensely beefy, so ideal pairings help cut through fat, add freshness, or complement the char.
Recommended Pairings for LongHorn® Porterhouse
| Category | Example Pairing | Why It Works |
| Starchy side | Baked potato, mashed potatoes, seasoned fries | Soaks up juices and balances saltiness with comfort-food texture. |
| Green vegetable | Steamed broccoli, side salad, green beans | Adds fiber and freshness to a heavy, fatty steak. |
| Grilled veggies | Grilled asparagus, mushrooms, onions | Echoes the grill flavors and adds umami without much extra fat. |
| Sauce / topping | Sautéed mushrooms, peppercorn sauce, garlic butter | Boosts umami and aroma; butter ramps richness, pepper adds bite. |
| Bread | House bread or rolls | Helpful to moderate strong seasoning and salty crust. |
| Beer | Malty amber ale or stout | Stands up to char and fat while cleansing palate. |
| Wine | Full-bodied red (Cabernet Sauvignon, Malbec) | Tannins cut fat and match the steak’s intensity. |
| Non-alcoholic | Sparkling water, unsweet iced tea | Bubbles or tannins refresh the palate between bites. |
These pairings follow general steak-pairing principles and are consistent with the strong, smoky profile of the LongHorn® Porterhouse.
How to Make LongHorn®* Porterhouse Recipe
LongHorn does not publish an official home recipe with exact seasoning ratios, but a copycat approach follows classic porterhouse technique: large bone-in steak, high-heat grilling, and a bold seasoning rub.
Key Steps for a LongHorn-Style Porterhouse at Home
Choose the Steak
Buy a porterhouse steak around 20–22 oz, at least 1.5–2 inches thick for good sear and juicy center.
Look for a steak with good marbling in the strip side and a well-sized filet portion.
Season Generously
Pat the steak dry, then coat both sides with kosher salt, black pepper, garlic powder, and onion powder, adding a touch of paprika or chili powder for color and a mild kick.
Let it sit at room temperature for about 30 minutes so seasoning adheres and the center is less cold before grilling.
Grill Over High Heat
Preheat a gas or charcoal grill to high heat; oil the grates lightly to reduce sticking.
Sear each side for several minutes to develop a dark crust, then move to a slightly cooler zone to finish to your preferred doneness using a meat thermometer.
Target Internal Temperatures
Approximate pull temperatures are:
- Rare: 50–52°C
- Medium-Rare: 55–57°C
- Medium: 60–63°C
Temperatures rise slightly while resting.
Because the filet and strip cook slightly differently, angle the thicker filet side closer to the hotter area if needed.
Finish and Rest
When the steak reaches target temperature, remove it and top optionally with a garlic-herb butter made from softened butter, garlic, parsley, and a pinch of salt.
Rest 5–10 minutes so juices redistribute, then slice across the grain, separating the filet and strip if serving plated.
This method does not duplicate LongHorn’s proprietary seasoning exactly but reproduces the core experience: a large, bone-in porterhouse with a deep sear, bold seasoning, and juicy interior.
LongHorn Porterhouse vs Outlaw Ribeye
Both the LongHorn® Porterhouse and the Outlaw Ribeye are signature, high-end steaks at LongHorn, but they differ in cut, texture, flavor, and even typical ranking in “best steak” lists.

| Feature | LongHorn®* Porterhouse | Outlaw Ribeye |

Final Thought
The LongHorn® Porterhouse stands out as a huge, showpiece steak that combines two prized cuts—filet and strip—on one T-bone, delivering roughly 1,250–1,280 calories, well over 120 g of protein, and a very high load of fat and sodium in a single entrée. For steak lovers, it offers both variety of texture and the theater of carving meat off a large bone, but for health-conscious diners, it is best approached thoughtfully. Consider sharing, pairing it with lighter sides, or choosing it as an occasional indulgence rather than an everyday meal.
To enjoy this steak at its best, it helps to understand its nutrition profile, allergen considerations, and pairings, and to know how to approximate it at home with a thick porterhouse, bold seasoning, and very hot grill. Whether compared with the Outlaw Ribeye or other LongHorn favorites, the Porterhouse earns its reputation mainly through size, protein punch, and classic steakhouse drama, making it a memorable choice for those who plan for its richness and respect its nutritional impact.
