How Many Calories Are in a Portion of Grilled Fillet Steak?

A 150-gram portion of grilled fillet steak contains roughly 320 calories. Fillet is one of the leanest cuts of beef, so it carries noticeably fewer calories than a fattier cut like ribeye or entrecôte of the same weight.

The meat is high in protein and carries almost no carbohydrate. That makes fillet a popular choice both for people watching their calorie intake and those preserving muscle mass; 150 grams supplies around 30 grams of protein.

How does the cooking method affect the calories?

Grilling or pan-searing fillet without added fat keeps the total low. A steak cooked in plenty of butter or fried in oil, on the other hand, can add 100-150 calories to the same portion — the added fat is a separate source, independent of the meat's own calories.

Doneness barely changes the count; the difference between rare and well-done fillet is only a few calories, since the loss mainly comes from water, not fat.

How do side dishes change the total?

The sauce and side served with fillet can easily carry more calories than the steak itself. A creamy mushroom sauce or buttery mash can roughly double the meal's total, while grilled vegetables or a green salad keep it low.

For anyone counting calories, the steak itself is a reliable choice — the sauce and side are what deserve attention. Even a small handful of fries alongside can push the total over 200 extra calories.

How does fillet compare with other cuts of beef?

A 150-gram entrecôte carries around 430-450 calories, and the same weight of ribs can go above 500; fillet's 320 calories sits well below both. The gap comes down to fat content — fillet is the least-worked part of the muscle, so it stores the least fat.

Minced beef varies widely depending on its fat percentage; a 150-gram patty made from 20% fat mince can carry 100-150 more calories than fillet. Restaurant fillet often runs higher than the home-cooked version too, since a butter sauce or a glossy finishing step can quietly add close to 100 calories before it reaches the table.

Resting the meat does not change its calories but does keep it juicy; letting a grilled fillet sit for a few minutes before slicing makes the same portion feel less dry and more satisfying. That will not lower the calorie count, but it does make one portion feel like enough. As a rough guide, a piece of fillet about the size and thickness of your palm is close to a 150-gram portion — a handy starting point when there is no scale around.
