Preheat your sous vide water bath to 80°C (176°F).
In a bowl, combine the mushrooms with the rest of the ingredients and toss to coat evenly. Place the mushroom mixture in the bag and seal using the water displacement method, or use a vacuum sealer.
Lower the bagged mushrooms into the water bath and cook for 30 minutes.
Remove the bag from the water bath and serve the mushrooms immediately.
