A typical 1 medium bagel serving of bagel contains 11.1 grams of protein (10.6 g per 100 g), which makes it a good source of protein. That covers roughly 22% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 16% of the calories in bagel come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 111 grains in the database, bagel ranks 4th by protein per serving, and 300th out of all 796 foods on the site. Set against kamut, another grain entry in the database, a serving carries about 1.3 g more protein (kamut has 9.8 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is counted by piece at 105 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
A bagel is dense, so one supplies as much flour as several bread slices.
