- "Years of going unpicked have allowed this hearty truffle to grow quite large. It's chock-full of nutrients. When cooked in a dish, it temporarily increases your maximum hearts."

Big Hearty Truffles are Materials from The Legend of Zelda: Breath of the Wild. They are curative items that restore Link's health by refilling three Heart Containers. They are rare mushrooms and valuable Hearty Truffles, that can be found near trees, stumps, and hollowed out trees. They are more common in the Hebra Mountains, Tabantha Tundra, Deep Akkala regions, and Akkala province. The traveling merchants Cambo and Kanny sell Big Hearty Truffles for 60 Rupees when it rains.
Link can cook with Big Hearty Truffles to grant the "Hearty" effect to dishes and Elixirs, which fully restores Link's health and gives Link additional temporary hearts. Big Hearty Truffles can be a main ingredient in Mushroom Skewer, Cream of Mushroom Soup, Fish and Mushroom Skewer, Fragrant Mushroom Sauté, Meat and Mushroom Skewer, Mushroom Omelet, Mushroom Rice Balls, Mushroom Risotto, Salt-Grilled Mushrooms, and Steamed Mushrooms. Effects do not stack in cooking, so Big Hearty Truffles cannot be paired with items of other effects without resulting in Dubious Food.
Link can roast Big Hearty Truffles by placing them on a Campfire or hot surface to create Toasted Big Hearty Truffles. Like all mushrooms, they cannot be frozen. Roasting does not transfer the "Hearty" effect of the dish; only cooking in a pot will transfer special effects.
Chio will reward Link with three Big Hearty Truffles if he talks to him once he completes the Shrine quests "Trial of Second Sight", "The Lost Pilgrimage", and "The Test of Wood" in the course of "The Korok Trials".
