If you're looking for a satisfying, wholesome alternative to traditional burgers, Portobello Mushroom Burgers are what you've been looking for. They are hearty, juicy, and packed with flavor. Whether you're fully plant-based or just trying to incorporate more veggies into your diet, this recipe is for you!
These quick and healthy portobello mushroom burgers are anything but ordinary! They have a savory, flavorful taste that will leave you wanting to finish every last bite. They can be grilled up outside or use a grill pan and cook them in.
Also, a fun fact: mushrooms are a natural source of glutamate, a naturally occurring compound that gives the fungi their umami flavor, and to really give these patties a savory boost, I brushed them with steak sauce, and right before eating, I spread the burger sauce onto the buns and devour them!
