Ready to grill some mushrooms? Mushrooms are a must-have for summer grilling, according to Katherine Salom, a Houston-based grilling enthusiast recognized on social media as @GirlGoneGrilling. “Mushrooms are the ultimate grilling ingredient – meaty, flavorful and perfect for soaking up marinades and seasonings,” Salom says. “With a range of varieties, each with their own size, shape, flavor and texture, mushrooms are delicious in a ton of grilling applications.”

Grilling mushrooms is a fantastic way to bring out their savory, umami-rich flavor while adding a bit of smokiness and char, Salom says. Mushrooms already are packed with flavor, but you can dial up the deliciousness with a quick marinade, especially global flavors that are a top grilling trend. “Mushrooms pair perfectly with a variety of marinades, so they easily bring those tasty global flavors to the grill,” Salom adds. From Korean BBQ and Asian-style glazes to Mediterranean herbs, flavors both savory and spicy shine with the versatility offered by grilled mushrooms.
