Seared Ahi Tuna

What's in the Seared Ahi Tuna?

At 410 calories per serving, the Seared Ahi Tuna represents about 21% of a 2,000-calorie daily intake. On the macronutrient side, roughly 27% of those calories come from protein, 61% from fat, and 12% from carbohydrates — a profile typical of Ruth's Chris Steak House's Appetizer 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 Seared Ahi Tuna with a side salad (dressing on the side) and water rather than a sweetened beverage is the standard mitigation. Like most items at Ruth's Chris Steak House, 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 Seared Ahi Tuna supplies 410 calories, which represents roughly 21% 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 27% protein, 12% carbohydrate and 61% 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 28g 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.

Allergen profile

Fish Soy Sesame

The Seared Ahi Tuna is flagged for Fish, Soy and Sesame in the chain's posted allergen panel. Soy normally arrives via soybean oil used for frying or via soy lecithin in commodity sauces, both of which are common across the casual-dining segment. Fish-derived ingredients can appear in unexpected places — Worcestershire-style sauces and Caesar dressings being the classic examples. Cross-contact in a shared kitchen is always possible, so when in doubt, ask the floor manager.

How it stacks up against the casual-dining category

Ordering strategy

If the Seared Ahi Tuna 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.
