Mushroom Gumbo — Extra-Dark Roux, One Pot, Big Flavour

#W2Kitchen #gumboMost mushroom gumbos split the job: brown mushrooms, drain, then make a separate roux—i.e., double the oil and throw flavour away. In this one-pot, vegetarian version we hard-brown chestnut, shiitake and king oyster, keep the mushroom oil, then build a Cajun-style extra-dark roux in that same flavoured fat before dropping in the Holy Trinity. Result: a meatless gumbo with roasted, coffee-like depth and real umami synergy from mushrooms (glutamate + guanylate), finished with clean heat and steamed rice. Technique-first, supermarket-friendly, maximum flavour.
