How to Make The Best Grilled Portobello Mushroom Burger
Step 1: Prepare the Marinade
In a large bowl, whisk together the balsamic vinegar, soy sauce, olive oil, rosemary, and Montreal steak seasoning until well combined.
Step 2: Marinate the Mushrooms
Place the portobello mushroom caps into the bowl. Toss them with the marinade using a spoon to coat evenly. Let them stand at room temperature for 20 to 30 minutes; remember to turn them occasionally.
Step 3: Preheat Your Grill
Heat your grill or indoor grill pan over medium heat. Once hot, brush the grate with oil or lightly spray the pan to prevent sticking.
Step 4: Grill the Mushrooms
Place the marinated mushrooms on the grill. Reserve some marinade for basting during grilling. Cook for about 5 to 7 minutes per side or until tender; baste frequently with reserved marinade.
Step 5: Add Cheese
During the last minute of cooking, top each mushroom cap with a slice of Swiss cheese so it melts perfectly.
Step 6: Grill Onions and Buns
While mushrooms are grilling, add thick slices of red onion to the grill. Grill each side for about one minute until slightly charred. Also toast your whole wheat buns until golden brown.
Step 7: Assemble Your Burger
On each toasted bun, place a layer of baby spinach followed by a grilled portobello mushroom cap topped with grilled onions, sliced tomatoes, and avocado. Enjoy your delicious creation!
