In our opinion, the best Kitchenaid stand mixer for bread dough is the Pro Line Series 7 Quart Bowl-Lift Stand Mixer. Its powerful 1.3 HP motor, large capacity mixing bowl, bowl lift feature, and 10 speed level control with slow start feature make it a formidable addition to any kitchen of a serious baker. It can handle large and heavy batches of dough easily without the threat of burning out and is really quiet compared to lots of other stand mixers. You also have the option to buy up to 15 additional attachments that can easily replace other small kitchen appliances, like a pasta maker, food grinder, juicer, etc.
