Outback Center-Cut Sirloin (6oz)

What's in the Outback Center-Cut Sirloin (6oz)?

At 290 calories per serving, the Outback Center-Cut Sirloin (6oz) represents about 14% of a 2,000-calorie daily intake. On the macronutrient side, roughly 61% of those calories come from protein, 37% 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 460mg, or about 20% of the FDA's daily reference value. If you're watching salt, pairing the Outback Center-Cut Sirloin (6oz) 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 Center-Cut Sirloin (6oz) supplies 290 calories, which represents roughly 15% of a 2,000-calorie reference day. That is on the lighter side for a sit-down restaurant entrée and gives a comfortable margin to add a starter, a side, or even dessert without crowding the day's caloric budget.

The macronutrient split lands at roughly 62% protein, 0% carbohydrate and 38% 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 44g per serving, which can keep satiety high relative to carb-heavy or fat-heavy alternatives.

Sodium clocks in at 460mg, or about 20% 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 Center-Cut Sirloin (6oz) 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.
