Mushroom Pizza is a food item that the player can cook. The recipe for Mushroom Pizza is obtainable inside a Precious Chest at Stormterror's Lair just north of the tower, or above the "o" in "terror" on the map.
Depending on the quality, Mushroom Pizza restores 26/28/30% of Max HP to the selected character, and regenerates 450/620/790 HP every 5 seconds for 30 seconds. Like most foods, this has no effect for other players in Co-Op Mode.
Unlike other dishes and despite the recipe being located in an overworld chest, acquiring Mushroom Pizza is required for Archon Quest progression. To unlock Chapter II Act II: Stillness, the Sublimation of Shadow, the Story Quest "Grus Nivis Chapter Act I: The Whispers of the Crane and the White Rabbit" must be completed. The quest Food From Afar uses Mushroom Pizza as part of the Story Quest.
- To celebrate Jean's birthday, the Teyvat Food Notes published a real-life recipe for Mushroom Pizza and Invigorating Pizza. Both pizzas use a cheesy garlic mushroom sauce instead of a tomato sauce, and Mushroom Pizza uses arugula (represented in-game with a cabbage) while Invigorating Pizza uses green bell peppers instead.
