Holy Shiitake Pie
The Holy Shiitake Pie is one of the signature specialty pizzas associated with Mellow Mushroom, bringing together roasted mushrooms, caramelized onions, multiple cheeses, garlic, herbs, and rich finishing flavors. It stands apart from traditional tomato-sauce pizzas because its foundation uses an olive oil and garlic base, allowing the mushrooms, cheese, and finishing ingredients to take center stage.
For mushroom lovers, this combination creates a pizza with a distinctly savory character. The roasted shiitake, button, and portobello mushrooms provide layers of earthy flavor, while caramelized onions add sweetness. Mozzarella and MontAmoré or aged white cheddar contribute richness, and the finishing touches of garlic aioli, black truffle oil, fresh chives, and Parmesan add additional depth. Current Mellow Mushroom listings describe the pizza with these core ingredients, although formulations can vary by location or menu update.
What Is Holy Shiitake Pie?
Holy Shiitake Pie is a mushroom-forward specialty pizza built around an olive oil and garlic base instead of the traditional red sauce used on many classic pizzas.
The current Mellow Mushroom menu lists Holy Shiitake among its specialty stone-baked pizzas and identifies it as a vegetarian option.
The pizza combines several varieties of mushrooms rather than relying on only one. Roasted shiitake, button, and portobello mushrooms create a varied mushroom profile, while caramelized onions introduce a naturally sweet contrast.
The cheese combination adds another layer of flavor. Current menu descriptions identify mozzarella together with MontAmoré or aged white cheddar, depending on the menu source and location. The pizza is then finished with garlic aioli, black truffle oil, fresh chives, and shaved Parmesan.

Because restaurant menus can change, we recommend checking the current menu at the specific Mellow Mushroom location when exact ingredients, nutrition, or allergens matter.
Olive Oil and Garlic Base
One of the defining characteristics of Holy Shiitake Pie is its olive oil and garlic base.
Unlike a traditional pizza built around tomato sauce, this base provides a more subtle foundation. The garlic brings savory intensity while the olive oil contributes richness and helps complement the roasted mushrooms.
This allows the mushroom flavors to remain prominent rather than competing with a strongly acidic tomato sauce.
The result is a pizza profile that leans toward garlic, herbs, roasted vegetables, melted cheese, and earthy mushroom flavors.
Roasted Shiitake, Button, and Portobello Mushrooms
The mushroom combination is the centerpiece of the pizza.
Shiitake Mushrooms
Shiitake mushrooms are known for their pronounced savory flavor and firm texture. On this pizza, roasted shiitake contributes an earthy, meaty mushroom character.
Button Mushrooms
Button mushrooms provide a familiar mushroom flavor and softer texture. Their relatively mild profile allows the stronger flavors from the shiitake and portobello mushrooms to remain balanced.
Portobello Mushrooms
Portobello mushrooms contribute a deeper mushroom flavor and substantial texture. Combined with shiitake and button mushrooms, they create a more complex topping than a pizza using only one mushroom variety.
Together, the three mushroom varieties make Holy Shiitake Pie especially appealing to mushroom enthusiasts.
Caramelized Onions Add Sweetness
Mushrooms provide primarily savory and earthy flavors, so caramelized onions serve an important balancing role.
The slow-cooked onions develop a sweeter, richer flavor that contrasts with the mushrooms and garlic. This creates a combination of savory, sweet, earthy, and creamy flavors.
The onions also soften during cooking, providing a different texture from the roasted mushrooms and crispier pizza edges.
Cheese on Holy Shiitake Pie
Cheese contributes richness and helps bring the toppings together.
Current descriptions identify mozzarella as part of the pizza and also list MontAmoré or aged white cheddar depending on the menu source.
Mozzarella provides the familiar melted-pizza texture, while the additional cheese contributes a more pronounced flavor.
The combination works particularly well with mushrooms because cheese can complement their savory character without overwhelming the garlic and roasted ingredients.
Garlic Aioli Swirl
The pizza is finished with a garlic aioli swirl, adding another layer of creamy garlic flavor.
Rather than being incorporated into the base, the aioli is applied as a finishing element. This means the garlic flavor can be more noticeable in individual bites.
For diners who enjoy garlic-forward pizza, the aioli is an important part of the overall flavor profile.
Black Truffle Oil Finish
Another distinctive finishing ingredient is black truffle oil.
Truffle oil is known for its strong earthy and aromatic character. A small amount can make a significant difference, especially when paired with mushrooms.
Because the pizza already contains several mushroom varieties, the truffle oil reinforces the earthy character and gives the finished pie a more sophisticated aroma.
Fresh Chives and Shaved Parmesan
Fresh chives provide a mild onion-like freshness that contrasts with the richer mushrooms, cheese, garlic, and truffle oil.
The pizza is also finished with shaved Parmesan, according to current menu descriptions.
Parmesan contributes a salty, savory finishing note and completes the layered flavor profile.
Together, the chives and Parmesan provide a fresh and savory contrast to the heavier components of the pizza.
What Does Holy Shiitake Pie Taste Like?
The flavor of Holy Shiitake Pie is best described as rich, savory, earthy, garlicky, and slightly sweet.
The mushrooms provide the dominant earthy flavor. Caramelized onions bring sweetness, while the olive oil and garlic base contributes savory depth.
Melted cheese adds creaminess, garlic aioli increases the richness, and black truffle oil reinforces the mushroom-forward character.
Fresh chives provide a lighter herbal note, while shaved Parmesan adds a final savory and salty finish.
The result is significantly different from a conventional pepperoni or red-sauce pizza.
Is Holy Shiitake Pie Vegetarian?
Yes. Mellow Mushroom currently lists Holy Shiitake as a vegetarian specialty pizza.
However, vegetarian diners with specific dietary restrictions should still check the current ingredients and preparation practices at their local restaurant.
Vegetarian does not necessarily mean vegan because the pizza contains cheese and other dairy-based ingredients.
Is Holy Shiitake Pie Vegan?
The standard Holy Shiitake Pie is not vegan because its listed ingredients include mozzarella, MontAmoré or aged white cheddar, and Parmesan.
Mellow Mushroom states that it offers plant-based options and dairy-free cheese for certain menu choices, but customers should confirm whether the current Holy Shiitake recipe can be modified appropriately at their specific location.
Holy Shiitake Pie Calories
Calories depend on the pizza size and current recipe.
One current menu listing reports approximately 380 calories for a small, 460 calories for a medium, and 490 calories for a large serving, while other location listings show slightly different ranges.
These figures should be treated as location- and menu-dependent rather than universal values.
When tracking calories, it is also important to understand what the listed serving represents. Pizza nutrition information is commonly based on an individual serving or slice rather than the entire pizza.
For the most accurate information, we recommend checking the restaurant’s current nutrition portal. Mellow Mushroom specifically directs customers to its nutrition resource for nutrition facts and allergen information.
Holy Shiitake Pie Sizes
Mellow Mushroom locations commonly offer specialty pizzas in multiple sizes. Current menu listings describe Holy Shiitake in small, medium, and large sizes, although availability and exact specifications can vary by location.
Choosing the right size depends on whether the pizza is being ordered for one person, shared among several people, or combined with other menu items.
For calorie tracking, the number of slices consumed is also important because the total pizza contains multiple servings.
Is Holy Shiitake Pie Gluten-Free?
The standard Holy Shiitake Pie is not automatically the same thing as a certified gluten-free pizza.
Mellow Mushroom currently states that it can prepare pizzas using its 10-inch Signature Gluten-Free Crust and says that certified gluten-free procedures are available for four specialty pizzas.
If gluten avoidance is medically necessary, customers should check the current gluten-free menu and ask about preparation procedures and cross-contact before ordering.
A gluten-free crust alone does not answer every allergen question. Preparation, toppings, sauces, utensils, and cooking procedures can also matter.
Holy Shiitake Pie vs. Traditional Cheese Pizza
A traditional cheese pizza typically emphasizes tomato sauce, mozzarella, and crust.
Holy Shiitake takes a different approach by using an olive oil and garlic base, multiple mushroom varieties, caramelized onions, additional cheese, garlic aioli, truffle oil, chives, and Parmesan.
This creates a more complex flavor profile with significantly more emphasis on mushrooms and garlic.
Cheese pizza is relatively simple, while Holy Shiitake is designed for diners who want a combination of toppings and finishing flavors.
Holy Shiitake Pie vs. Veg Out
Both pizzas can appeal to vegetarian diners, but their flavor profiles are quite different.
Veg Out uses Mellow red sauce with mozzarella, spinach, green peppers, mushrooms, onions, black olives, and tomatoes. Holy Shiitake instead focuses on roasted shiitake, button, and portobello mushrooms, caramelized onions, an olive oil and garlic base, and rich finishing ingredients.
The choice therefore comes down largely to flavor preference.
Those who enjoy mushrooms, garlic, caramelized onions, and truffle flavors may gravitate toward Holy Shiitake, while diners looking for a broader vegetable combination with tomato sauce may prefer Veg Out.
Best Toppings and Customization Ideas
The standard Holy Shiitake combination is already designed around a strong mushroom profile, but available customization can vary between locations.
Potential modifications should be discussed with the restaurant when ordering. Removing ingredients can change the balance of flavors, while adding additional toppings can affect nutrition and overall taste.
For customers with food allergies, customization should be communicated clearly so that staff can explain which options are appropriate and how the order will be prepared.
Why Mushroom Lovers Choose Holy Shiitake
The defining advantage of Holy Shiitake is its commitment to mushrooms.
Instead of using mushrooms as one minor topping among many, the pizza combines three mushroom varieties and reinforces them with black truffle oil.
This creates a mushroom-forward experience from the first bite to the last.
The caramelized onions prevent the flavor from becoming one-dimensional by adding sweetness, while garlic and cheese contribute richness.
For people who regularly order mushroom pizza, Holy Shiitake offers a more layered alternative to a simple mushroom-and-cheese combination.
