With the Anova Sous Vide Precision Cooker, we can ensure large mushrooms like the king oyster (or trumpet) are perfectly tender throughout — from the softer cap to the firmer stem—while infusing with mouth-watering garlic and herb flavor. To create textural and flavor contrast, we finish in brown butter, crisping to a deep, buttery golden brown and serving with fresh herbs, lemon, and cheese. It's the perfect side for an elegant holiday meal or as base for vegetarian entree.
