I Am Bread received mixed reviews upon release, with some praising its uniquely humorous premise and challenging gameplay, while others criticized its controls and repetitive nature.

Several expansions have added various features, such as having players play as a baguette bent on destroying any fragile object in the room, a bagel that races around the room, and as a fragile cracker that seeks to find slices of cheese and have them stick to it while avoiding disintegration by repetitive impacts on surfaces.

Another bonus level has a slice of bread seeking to find and complete an unfinished sandwich in the refrigerator inside a room with a slumbering Heavy as a crossover with Team Fortress 2.

He is distressed over alleged break-ins into his house with the culprit supposedly leaving behind pieces of toasted bread as a taunt or warning.

Some time after the crash, Nigel Burke, a mysterious man with a watch, pulls over and investigates and grabs Mr. Murton off-screen, and in front of the car is a Barnardshire Sign indicating that I am Bread is a prequel to Surgeon Simulator 2013, another game by Bossa Studios.
