How to Make The Best Grilled Portobello Mushroom Burger

Step 1: Prepare the Marinade

In a large bowl, whisk together balsamic vinegar, soy sauce, olive oil, chopped rosemary, and steak seasoning until well combined.

Step 2: Marinate the Mushrooms

Place the portobello mushroom caps in the bowl with the marinade. Toss gently using a spoon to coat evenly. Let them sit at room temperature for 20 to 30 minutes, turning occasionally.

Step 3: Preheat Your Grill

Heat your grill or indoor grill pan over medium heat. When hot, brush the grate with oil or lightly spray it to prevent sticking.

Step 4: Grill the Mushrooms

Place the marinated mushrooms on the grill. Reserve some marinade for basting. Grill each side for 5 to 7 minutes or until tender. Brush frequently with reserved marinade during grilling.

Step 5: Add Cheese

During the last minute of grilling, place thin slices of Swiss cheese on top of each mushroom cap to melt slightly.

Step 6: Grill Onions & Buns

While cooking the mushrooms, grill red onion slices for about one minute on each side until they are caramelized. Toast whole wheat buns on the grill until golden brown.

Step 7: Assemble Your Burger

To finish your burger, layer baby spinach on each bun followed by the grilled portobello mushroom caps. Top off with grilled onions, sliced tomatoes, and avocado before placing the other half of the bun on top.
