Every 100 kcal of challah brings 3.3 g of protein. On that measure it ranks 56th of the 111 grains in this database and 597th of all 796 foods on the site. Measured by weight instead, its 9.5 g per 100 g ranks 48th in its group.
Around 13% of the calories in challah 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.
Weight for weight, challah has 1.6 g of protein for each gram of fat (9.5 g against 6 g per 100 g).
Set against triticale flour, another grain entry in the database, a serving carries about 0.5 g less protein (triticale flour has 4.3 g per 1/4 cup).
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 quoted here is counted by piece at 40 g, and it covers about 8% of the 50 g FDA Daily Value for protein.
Enriched with egg, which lifts the protein above plain white bread.

How much protein do you get per 100 calories of challah?
3.3 g. That figure divides its 9.5 g of protein per 100 g by its 287 kcal per 100 g, so it does not depend on serving size.
Is the protein in challah complete?
No. On its own, the protein in challah is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of challah?
About 8%. One 1 slice serving has 3.8 g, and the FDA Daily Value for protein is 50 g.
