Porterhouse (22oz)

What's in the Porterhouse (22oz)?

At 1320 calories per serving, the Porterhouse (22oz) represents about 66% of a 2,000-calorie daily intake. On the macronutrient side, roughly 39% of those calories come from protein, 59% from fat, and 0% from carbohydrates — a profile typical of LongHorn Steakhouse's Steak section. Sodium is often the line to watch with sit-down chain entrees, and this dish delivers 1410mg, or about 61% of the FDA's daily reference value. If you're watching salt, pairing the Porterhouse (22oz) with a side salad (dressing on the side) and water rather than a sweetened beverage is the standard mitigation. Like most items at LongHorn Steakhouse, the dish is built for shareable portions and is plated at restaurant scale rather than a strict single serving. Boxing half of it before you start is one of the simplest ways to bring the per-meal calorie load down meaningfully without giving up the experience.

How this fits a 2,000-calorie day

One serving of the Porterhouse (22oz) supplies 1320 calories, which represents roughly 66% of a 2,000-calorie reference day. That puts the dish into the indulgent end of the casual-dining spectrum — closer to a daily caloric ceiling than to a single weekday meal. Splitting the plate or boxing half before you start eating is the simplest way to bring the per-meal load down meaningfully without skipping the experience.

The macronutrient split lands at roughly 40% protein, 0% carbohydrate and 60% fat by calorie share — a useful frame because raw gram counts often understate how much of a dish's energy actually comes from fat. Protein delivery is meaningful here at 128g per serving, which can keep satiety high relative to carb-heavy or fat-heavy alternatives.

Sodium clocks in at 1410mg, or about 61% of the FDA's 2,300mg daily reference value. That is on the higher end for a single restaurant serving. It still fits a normal day if other meals are light, but two restaurant meals in a row at this sodium level will add up quickly. Saturated fat is the other line worth watching at 36g — about 180% of the daily reference value — primarily a long-term cardiovascular consideration rather than a single-meal one.

Allergen profile

No major allergens flagged

No major allergens are flagged on this item in the chain's posted nutrition disclosure. That said, every full-service restaurant kitchen handles wheat, dairy, eggs and seafood somewhere on the line, so cross-contact remains possible. If you have a severe allergy, telling the server before ordering — and asking for the manager's confirmation that the kitchen can accommodate — is the standard precaution.

Ordering strategy

If the Porterhouse (22oz) is the entrée you want, the highest-leverage adjustments are usually the ones that change the surrounding meal rather than the dish itself. Splitting one entrée between two diners and adding a soup or salad starter typically results in a more satisfying meal at a lower per-person calorie load than each person ordering their own full-size plate. LongHorn Steakhouse portions, like most casual-dining chains, are sized to be shareable. Asking for a take-home box at the start of the meal — and immediately moving half the dish into it — is the single most reliable behavioral lever for managing portion drift over the course of dinner. Sauces, dressings and finishing oils are routinely the largest hidden source of calories on a casual-dining plate; getting them on the side gives you direct portion control without changing the dish you actually want to eat.
