Why don’t people talk about more portobello mushrooms? Or maybe they do and I’m just living under a rock because I tried them over the weekend and they are so amazingly good!

Portobello mushrooms are so good that I had to create a portobello recipe with an Asian twist!  

So I came up with a simple miso marinade, similar to the one I use to make my miso cod, and decided to let it sit in the fridge for a few hours to see how they turn out.  

After a quick bake, these miso marinated portobello mushrooms were out of this world! 

Amazingly juicy, and packed with umami flavor!  

This dish is simple enough to make as a side and hearty enough to be a main. The choice is yours!

What are portobello mushrooms and are they keto friendly?

Portobello mushrooms are meaty mushrooms, rich in flavor with a large flat cap. They are keto friendly coming in at about .5 g net carbs per mushrooms.  

Can I substitute cayenne pepper for chili pepper?

Yes, but remember that cayenne pepper packs 8 times more heat than chili pepper. So make sure to substitute accordingly.

It is best to grill, bake or pan fry portobello mushrooms?

Portobello mushrooms can be cooked all different ways, however, I prefer baking or grilling them. 

Just cook them at 350F for 8-10 minutes and you are good to go!  

How long should you marinate portobello mushrooms for?

We recommend at least 8-12 hours, but you can go up to 24 hours.

What kind of miso do you recommend using for these baked portobello mushrooms?

There are two main types of miso, shio (white) miso and akamiso (red).  

While shio miso is lighter with both salty and sweet flavor, red miso is more bold and pungent in flavor. 

But the one we actually prefer is awase or brown miso, which is a mix of both white and red miso and therefore, the best of both worlds. It works great for all kinds of Asian recipes!  

The best place to get miso is at your local Asian supermarket and if you have trouble finding one, just ask and I’m sure they will make a great recommendation!

For this recipe, the special ingredients you will need are Awase Miso, Monkfruit and Japanese sake.  All these can be picked up on Amazon (aside from Japanese sake) or a local Asian/specialty Supermarket.

Now, let’s get baking some of the best miso portobello mushrooms you’ve ever had!
