Ready to fire up the grill? Give beef a break with a grilled Portobello mushroom burger. The simple marinade makes them tangy and flavorful.
What is a Portobello Burger Made of?
Portobello burgers are made with Portobello mushrooms instead of ground beef like traditional burgers. The large mushroom caps are similar in size, shape and texture.
However, grilled Portobello mushroom burgers do not taste like hamburgers. The mushrooms are soaked in a savory, sweet and tangy marinade. These flavors are complimented with the usual burger toppings, such as lettuce, tomato and onion to form the perfect bite.
How to Prepare Portobello Mushrooms
It is quick and easy to prepare Portobello mushrooms for the grill. Begin by removing the stems. Then given the mushroom caps a rinse, and dry them with a paper towel or clean cloth.
Be careful not to apply too much pressure when drying the mushroom caps. They can split.
How Do I Make My Portobello Mushroom Not Soggy?
Grilling Portobello mushrooms is a great way to ensure they don’t come out soggy. The marinade and any extra moisture will drip into the grill while cooking. Pan frying or baking Portobello mushrooms may leave them soggy. Using an Air Fryer is a great option, but using a liner could result in some sogginess.
