I couldn’t find a recipe for making dried beans sous vide for my Sous Vide Supreme, so I winged it. It worked really well.
1 cup dried black beans, rinsed 1 diced medium red onion Roughly the same volume of beans in ice cubes
Preheat SVS to 180F. Seal all ingredients in a vacuum bag.
Cook for 36 hours. After 24 hours, I squeezed the bag and it still felt a little firm, so I put them back in. The beans were completely tender all the way through, but not squishy and had a really pleasant texture. Salt to taste before serving.
