Grilled Portobello Mushroom Burger: The Perfect Vegan Treat

Grilled portobello mushroom burgers are so palatable that even a serious meat eater will fall in love with them. The best part is that it is healthy for you. These mushrooms from Italy contribute majorly to the delightfulness of these burgers. So, let’s take a look at how to prepare these tempting burgers!

Key attributes of Grilled Portobello Mushrooms

The reason why I love grilled vegetables is because of their simplicity. Portobello mushrooms taste better than other mushrooms because of their meaty texture. Furthermore, grilled portobello mushrooms are also an amazing alternative for beef. 

It is because they are very less in fat and calorie content. Additionally, portobello mushrooms are a good source of nutrients like selenium and vitamin B2. The preparation of this dish takes very little time and requires very few ingredients.

Do not forget to remove the gills of the portobello. It is important as it might alter the color and taste of the dish. As far as the bread goes, I recommend the homemade sourdough bread for this particular recipe.

Preparing the Patty

We will start by cleaning the mushroom caps as it is the most crucial part of the preparation. So, trim the stems and scoop out the gills. To avoid the top of the mushroom from becoming too chewy, draw a cross pattern gently with your knife.

Quick Tip: Drawing the cross pattern also helps the marinade to blend better in the mushroom.

Now, we will marinate the mushroom in the same way we marinate the meat before grilling. Use a large bowl for this step. It is better to coat the fungi with balsamic vinegar, olive oil, salt, and pepper.

After that, put the mushrooms in with the mixture. Once it is done, let it be there for at least half an hour (one hour is better). The mushrooms are now ready for grilling.

It's time to grill

  • Preheat the grill to a medium-high temperature. Clean the grill, dip a paper towel in oil and clean the cooking grates with a pair of tongs.
  • The main objective here is to achieve a mushroom that is juicy, soft, and charred at the same time. Make the gill side of the mushrooms face up. It will create brown spots on the other side. Cover it and let it cook for five minutes.

Quick Tip: Grilling with the gills facing upwards will also help make the juices stay in the cap.

  • Flip sides and add the cheese to it. Cover and let it cook till the cheese melts. The moisture will start evaporating now, and it will prevent the mushroom from being soggy. Let this side cook for five minutes.
  • You can remove the mushrooms after it is thoroughly done. Side by side, do not forget to toast the burger buns. Once it is done, place the mushrooms on the buns. You are now free to add the toppings according to your likes.

The dish is now ready to serve. I suggest tomatoes, lettuce, red pepper, pesto sauce, and mayo as the perfect toppings.

Key Tips:
  1. Removing the gills of the mushroom is easy. All you need to do is twist the stem. You can eat the gills if you want. But, it brings a very dark color which most people do not like, therefore, it is ideal to remove it.
  2. Only select firm mushrooms. Do not go for the ones that are limp.
