- Combine onions, soy sauce, and sugar in bowl and microwave until just softened, about 5 minutes, stirring halfway through cooking. Spread onions and their liquid in bottom of slow cooker. Arrange bratwursts in single layer on top of onions.
- Whisk beer, mustard, and caraway seeds together in bowl and add to slow cooker. Cover and cook until bratwursts are tender, 6 to 8 hours on low or 4 hours on high.
- Transfer bratwursts to platter and tent loosely with aluminum foil. Stir sauerkraut into onion mixture in slow cooker and let sit until warmed through, about 5 minutes. Strain onion-sauerkraut mixture through colander, discarding liquid, and transfer to serving bowl. Serve bratwursts on rolls, topped with onion-sauerkraut mixture and mustard.
