For the mushroom stock: Preheat your oven to 450°F (232°C). In a large bowl, toss together the mushroom, onion, garlic, carrot, celery, 4 tablespoons of vegetable oil and kosher salt. Spread onto two foil-lined sheet trays. Roast until deeply browned, about 45 minutes, tossing vegetables every 15 minutes.
