A typical 1 piece serving of focaccia contains 5 grams of protein (8.77 g per 100 g), which makes it a moderate source of protein. That covers roughly 10% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 14% of the calories in focaccia 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, focaccia ranks 43rd by protein per serving, and 496th out of all 796 foods on the site. Set against gluten-free pasta, another grain entry in the database, a serving carries about 0.5 g more protein (gluten-free pasta has 4.5 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 57 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
