One piece of brioche is a 329-calorie bread
A single 77 g piece of bakery brioche carries 329 calories, which is 16% of the daily calorie value used on this page. The small serving of 70 g lands at 299 calories, or 15%. Those two portions sit close together, so the size of the piece matters less than how many pieces end up on your plate.
Multiples climb fast. Two pieces add up to 658 calories and 673 mg of sodium. Three pieces reach 986 calories, and five pieces hit 1,644 calories with 1,682 mg of sodium. Brioche is soft, sweet and easy to eat, which is exactly why the second piece tends to slip in unnoticed.
If you use a 77 g piece as a burger bun, the bread alone brings 329 calories before the patty, cheese or sauce. That is a real share of a meal. Rolls from St. Pierre, H&S Bakery or Macrina Bakery come in different sizes, so weigh one or read the label weight and scale from the 427 calories per 100 g figure.
Fat supplies 58% of the calories
Per 100 g, brioche has 27.5 g of fat, 36.3 g of carbs and 9 g of protein. By calories, fat makes up 58%, carbs 34% and protein 8%. That split is what separates brioche from lean bread, where carbs usually lead. Here the rich dough pushes fat to the top of the list.
Sugar is lower than the sweet taste suggests. One piece carries 2.4 g of sugars and 1.2 g of fiber, and 100 g holds 3.1 g of sugars. Most of the carbs are starch from the flour, not added sweetness. The flip side is that fiber is thin, at 1.5 g per 100 g.
Protein is modest. A piece gives 6.9 g, 14% of the daily value, and even two pieces only reach 13.8 g. If you track macros, count brioche as a fat source first and a carb source second. That framing makes it easier to decide what else belongs on the plate.
Saturated fat is the row to watch
Brioche holds 14.3 g of saturated fat per 100 g, against a daily value of 20 g. In plain terms, 100 g of brioche covers most of the reference amount before anything else is eaten. Cholesterol follows the same pattern at 174 mg per 100 g, compared with a daily value of 300 mg.
Sodium is moderate by comparison. One piece has 336 mg, 15% of the daily value, and the 70 g serving has 306 mg, or 13%. It adds up with multiples: three pieces bring 1,009 mg. Pair brioche with cured meat or salty cheese and the sodium row grows quickly.
If you watch saturated fat, one piece is the portion to plan around, and the spread you add matters. Butter on brioche stacks fat on a bread that already gets 58% of its calories from fat. A thin layer of jam or fruit changes the total far less.
Pair brioche with protein, not more fat
Because protein is only 8% of the calories, brioche works best next to a food that fills that gap. Eggs, turkey, chicken or a lean patty balance a brioche sandwich far better than bacon and extra cheese. A side of fruit or vegetables adds the fiber the bread lacks.
Brioche fits a day of eating as a planned treat rather than a default bread. One piece at breakfast with eggs and fruit is easy to account for. A brioche burger plus fries is a different story, because both lean on fat. If you eat it often, swapping in a smaller roll is the simplest lever.
Logging it is quick: BodyPal can log brioche from a photo, and you can adjust the grams if your roll is larger or smaller than the 77 g piece used here. Accurate weight beats guessing, since every extra 100 g adds 427 calories.
How does brioche compare?
Here is how brioche stacks up against concha and a chocolate croissant, per 100 g and per usual serving.
Verdict: Brioche is the richest of the three at 427 calories and 27.5 g of fat per 100 g, while a chocolate croissant has 421 and a concha 408. For the fewest calories per serving pick a concha at 290; for the most protein per 100 g brioche leads with 9 g.
