White button mushrooms and portobello mushrooms are the same species, known as Agaricus bisporus. The only difference between the two is the age at which they are harvested. White button mushrooms are the youngest and most immature form of Agaricus bisporus, while portobello mushrooms are the largest and fully mature version of the same species. As portobello mushrooms grow larger, they lose some of their water content, resulting in a drier texture and a more concentrated flavor compared to white button mushrooms.

What You'll Learn
Portobello mushrooms are the adult version
Button mushrooms, which are white, are the toddlers of the species. They are the youngest and most immature form of Agaricus bisporus. They have a mild, almost bland flavour, but this can be transformed into something delicious when cooked with butter and salt.
Cremini mushrooms, also known as baby bella mushrooms, are the teenagers. They are slightly older than button mushrooms but are still juvenile compared to portobellos. They have a firmer texture and a more earthy flavour than their younger counterparts.
Portobellos, as the adults, have had the most time to grow and develop. This means they hold less moisture than the younger mushrooms, giving them a drier, meatier texture. Their flavour is also more concentrated, making them the most flavourful of the bunch. They are excellent choices for grilling or roasting and can even be used as meat substitutes in some recipes.
All three types of mushrooms are the same species and have very similar nutritional values. They are great sources of B vitamins and important minerals such as copper, phosphorus, and potassium. They also contain high concentrations of Vitamin D if they have been exposed to sunlight or other UV light.

White mushrooms are the immature form
White mushrooms, also known as white button mushrooms or common mushrooms, are the youngest and most immature form of Agaricus bisporus. They were developed in the early 1920s by Pennsylvania mushroom farmer Louis Ferdinand Lambert specifically for their white colour. White mushrooms are typically harvested early in the growth cycle of the Agaricus bisporus fungus, which is native to grasslands, fields, and meadows across Europe and North America.
White button mushrooms have a mild, almost bland flavour that makes them versatile in the kitchen. They are often used in pickling, marinading, and stroganoff. When cooked with butter and salt, their flavour can be transformed into something delightful. White mushrooms are also a good source of B vitamins, riboflavin, pantothenic acid, copper, phosphorus, and potassium.
As Agaricus bisporus mushrooms mature, they start to brown and are then known as cremini or baby bella mushrooms. These are slightly older than button mushrooms but are still juvenile compared to portobello mushrooms. Cremini mushrooms have a firmer texture and a more earthy flavour than white buttons. They are often marketed under various names, such as baby portobello, mini bella, Italian brown mushrooms, and more.
Portobello mushrooms are the largest and most mature form of Agaricus bisporus. They have had more time to develop a stronger flavour and a drier, meatier texture. Portobellos are excellent for grilling or roasting and can be used as meat substitutes or bread bun replacements in certain diets. All three types of mushrooms—white button, cremini, and portobello—have similar nutritional profiles due to being the same species.

They are the same species
Portabella mushrooms and white mushrooms are the same species. Scientifically known as Agaricus bisporus, these mushrooms are commonly marketed under different names, such as white buttons, baby bellas, cremini, portobellos, and more. The only difference is that they are picked at different stages of maturity, giving them distinct textures, flavours, and sizes.
White button mushrooms, the youngest of the bunch, have a mild flavour and a white appearance. They are often used in pickling and marinating due to their subtle taste. As they mature, they transform into baby bellas or cremini mushrooms, which exhibit a brown hue and a firmer texture. Their flavour also becomes more pronounced, taking on a classic earthy and umami-rich profile.
Portobello mushrooms, the adults of the species, are the largest and most mature version of Agaricus bisporus. They have had more time to develop their flavour, resulting in a stronger, savoury, and umami-rich taste. Their texture becomes drier and meatier, making them excellent meat substitutes for grilling or roasting. They are also commonly used as bread bun substitutes for those following a Paleo, Keto, or low-carb diet.
While these mushrooms share the same species classification, their differences in maturity lead to variations in their culinary applications. White button mushrooms, with their mild flavour, are versatile and can be used in various dishes. Baby bellas, with their firmer texture and richer flavour, add a distinct earthy note to recipes like stroganoff. Portobello mushrooms, with their intense flavour and meaty texture, can be a satisfying component in vegetarian dishes.
Despite their differences in appearance, flavour, and texture, portabella and white mushrooms are indeed the same species. Their varying ages and selective breeding for colour contribute to the distinct characteristics that make each type unique in the kitchen.

White mushrooms are milder in flavour
White mushrooms, portobellos, criminis, and baby bellas are all the same species of mushroom—Agaricus bisporus. They are, however, harvested at different stages of maturity, which accounts for their differences in texture, flavour, and size. White mushrooms are the youngest and most immature form of Agaricus bisporus, and they have a milder flavour compared to their older counterparts.
The mild flavour of white button mushrooms makes them a versatile ingredient in the kitchen. They can be pickled, marinated, or fried with butter and salt to enhance their flavour. White mushrooms are also suitable for dishes like stroganoff, where their subtle flavour can be assimilated by the sauce. When cooked, it is important to ensure that white mushrooms are as dry as possible. Cooking over medium-high heat in a small amount of oil, without overcrowding the pan, allows moisture to escape.
White mushrooms develop a brown colour as they mature into the crimini or baby bella stage. These older mushrooms have a firmer texture and a more earthy, umami-rich flavour. They are often marketed under various names, such as baby portobello, mini bella, Italian brown mushrooms, and more.
The fully mature version of Agaricus bisporus is the portobello mushroom. It has the strongest flavour of all the stages and a drier, meatier texture. Portobellos are excellent for grilling or roasting and can even be used as a meat substitute or bread bun replacement for certain diets. With their deeper flavour and larger size, portobellos stand out as the most flavourful of the Agaricus bisporus varieties.

Portobello mushrooms are drier and meatier
Portobello mushrooms are indeed the same species as white mushrooms, Agaricus bisporus, but they are harvested at different stages of maturity. White mushrooms are the youngest, most immature form of the species, while Portobellos are the largest, fully mature version. As mushrooms age, they lose some of their water content, which makes Portobellos drier and meatier than their younger counterparts. This also gives them a stronger flavour, making them a good choice for grilling or roasting.
Portobello mushrooms are sometimes referred to as portabella mushrooms. They are brown and much larger than white mushrooms. As the mushrooms mature, they develop a firmer texture and a deeper, earthier flavour. This makes them a popular choice for recipes that require a meatier texture, such as vegetarian dishes or grilling on a BBQ.
White mushrooms, on the other hand, have a milder flavour and are often used in recipes such as stroganoff, where their more subtle taste can be assimilated by the sauce. They are also a good candidate for pickling and marinating due to their more delicate flavour.
The nutritional value of Portobello and white mushrooms is extremely similar, as they are the same species. They are great sources of B vitamins, especially riboflavin and pantothenic acid, and contain significant amounts of important minerals like copper, phosphorus, and potassium. If exposed to sunlight or other UV light, they can also be a source of Vitamin D.
When cooking with mushrooms, it is important to ensure they are as dry as possible before starting. Mushrooms should be cooked over medium-high heat in a small amount of oil, and it is important to avoid overcrowding the pan so that moisture can escape. Salt and aromatics should be added after the mushrooms have released most of their water, and butter or ghee can be added towards the end of the cooking process.
