What Is A Portobello Mushroom?
These mushrooms are hard to miss.
Portobello mushrooms are large in size and have a smooth, spongy cap with an average diameter of fifteen centimeters. This dark brown, tan-colored cap is often connected to a thick stem with fleshy gills on the underside.
If you are familiar with the button mushroom, just think of the portobello as the bigger, older brother.
It is the same mushroom, only it is allowed to mature and grow larger before being picked.
Why is it called a Portobello (or Portabella ) Mushoom?
First off, just know that you would be correct in calling this mushroom a “portobello” or a “portabella.”
“Portabella” is just a marketing term. (Sounds like something pretty, right?)
However, the portobello mushroom’s name has a few origins, or theories.
One theory is the direct translation of the name, meaning “beautiful door.”
The second is that the mushroom is named after an exclusive shopping street in London.
Another possible origin is that the name came from a TV show named “Portobello“.
Some say that the portobello mushroom is named after a city in Panama.
In the end, it’s still a tasty mushroom, however, it got the name!
What Do Portobello Mushrooms Taste Like?
When cooked, Portobello mushrooms have an earthy flavor and are known for their chewy texture and meatiness!
Its rich flavor is attributed to the spores that are released from the gills and is often described as umami.
Portobello mushrooms taste very similar to its smaller version of the button and cremini mushrooms, but just a bit more intense.

Tip:
How to store your portobellos
Never store mushrooms in plastic (like the way you may have purchased them), rather in paper bags to avoid them retaining moisture and developing a “slimy” coating!
How Do I Clean My Portobello Mushrooms?
Cleaning your mushrooms is as easy as taking a paper towel and brushing off any excess dirt or foreign particles. DO NOT rinse or soak in water – the mushrooms will absorb it and it will result in less than perfect taste and texture.
How Do You Cook Portobello Mushrooms?
The 3 main techniques for cooking portobello mushrooms are:
- Sautee’ – sliced and sauteed in a pan with oil or butter
- Grilled – often marinated and grilled over high heat
- Oven – generally seasoned and either baked or roasted (with or without stuffing)
Different Ways to Eat Portobello Mushrooms:
- Grilled and used as a “burger” in place of meat; or, as the “buns” for a low-carb burger option
- Marinated and grilled as a “steak”
- Sliced and sauteed as a side dish, in a pasta dish, or in a rissotto
- Stuffed with minced meat, cheese or vegetables then baked or roasted
What is the difference between baked and roasted portobello mushrooms?
The difference between baked and roasted portobello mushrooms is the cooking temperature.
When portobellos are baked at a lower temperature (between 325 and 350 degrees) for a longer cook time, the result is a more tender, outer texture.
When portobellos are roasted at a higher temperature (between 425 and 450 degrees) for a shorter cook time, the result is a more firm and crispier outer texture.
How To Make Roasted Portobello Mushrooms
This is a step-by-step of how I stuffed my portobello mushrooms with creamy goat cheese and spinach and roasted them in a savory pumpkin sauce.
Step 1:
Prepare your portabello caps by cleaning them with a dry paper towel or cloth.
Step 2:
Brush the caps with olive oil on both sides and season with salt and pepper.
Step 3:
Prepare the “bread crumbs” by browning the almond flour seasoned with salt, pepper, and fresh parsley in a pan.
Remove browned almond flour and wilt the spinach in the same pan, seasoning it with salt and pepper. Alternately, you may use frozen spinach that is well-drained of excess moisture
In a bowl, prepare the filling by mixing the goat cheese, egg, spinach, salt, pepper, and nutmeg.
Step 4:
Fill the portobello mushroom caps with the goat cheese mixture, breadcrumbs, and Parmigiano Reggiano. Set aside.
Step 5:
Sautee sliced garlic in olive oil until lightly browned. Remove garlic from the oil. Place pumpkin puree, non-dairy cream, sage, salt, and pepper into the pan on medium heat and stir to create a smooth and creamy sauce. Once heated through, transfer the sauce to a baking dish and place the mushrooms on top.
Step 6:
Place the baking dish in the oven and roast at 425 degrees for 10 minutes and until the cheese is bubbling and the breadcrumbs have a nice dark golden color. Remove and let cool before serving the roasted portobello mushrooms on top of the savory pumpkin sauce.
How to Serve The Roasted Portobello Mushrooms:
- 2 mushrooms as a main dish with a side salad
- 1 mushroom as an appetizer
