A typical 1 cup serving of baked beans contains 12.1 grams of protein (4.75 g per 100 g), which makes it a good source of protein. That covers roughly 24% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 20% of the calories in baked beans come from protein, so it is moderately protein-dense. 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 54 legumes in the database, baked beans ranks 35th by protein per serving, and 290th out of all 796 foods on the site. Set against canned black-eyed peas, another legume entry in the database, a serving carries about 0.7 g more protein (canned black-eyed peas has 11.4 g per 1 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 above is measured by volume at 254 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
