Outback Special Sirloin (11oz)

What's in the Outback Special Sirloin (11oz)?

At 520 calories per serving, the Outback Special Sirloin (11oz) represents about 26% of a 2,000-calorie daily intake. On the macronutrient side, roughly 61% of those calories come from protein, 36% from fat, and 0% from carbohydrates — a profile typical of Outback Steakhouse's Steak section. Sodium is often the line to watch with sit-down chain entrees, and this dish delivers 820mg, or about 36% of the FDA's daily reference value. If you're watching salt, pairing the Outback Special Sirloin (11oz) with a side salad (dressing on the side) and water rather than a sweetened beverage is the standard mitigation. Like most items at Outback 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 Outback Special Sirloin (11oz) supplies 520 calories, which represents roughly 26% of a 2,000-calorie reference day. That is a moderate restaurant-portion meal — generous compared to a home-cooked plate but not at the upper end of the chain's menu. A side salad or a smaller appetizer can round it out without pushing the day over budget.

The macronutrient split lands at roughly 63% protein, 0% carbohydrate and 37% 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 79g per serving, which can keep satiety high relative to carb-heavy or fat-heavy alternatives.

Sodium clocks in at 820mg, or about 36% of the FDA's 2,300mg daily reference value. That is well within a reasonable share for a single meal and gives plenty of room for the rest of the day.

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 Outback Special Sirloin (11oz) is the entrée you want, the highest-leverage adjustments are usually the ones that change the surrounding meal rather than the dish itself. Because the entrée itself is moderate, you have headroom for an appetizer or a starter side without dropping into restrictive territory — useful for a longer dinner where the goal is to stretch the meal rather than minimize it. 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.
