Ingredients

I set out to make a great tasting grilled portobello mushroom burger that even a meat lover would love. The mushrooms are marinated then grilled and topped with melted Swiss Cheese, grilled red onion, tomatoes, spinach, and avocado – yum!!

For the Burger:

• 4 portobello mushroom caps
• 2 tbsp balsamic vinegar
• 1 tbsp low sodium soy sauce
• 1 tbsp olive oil
• 1 tbsp chopped rosemary
• 1-1/2 tsp steak seasoning like Montreal Steak Grill Mates
• 4 thick slices red onion
• 4 oz reduced fat Swiss (sliced thin)
• 4 thin slices tomato
• 1/2 avocado (sliced thin)
• baby spinach
• 4 whole wheat low calorie buns (I used Martin)

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, chopped rosemary, and Montreal steak seasoning until well combined.

Step 2: Marinate the Mushrooms

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

Step 3: Heat the Grill

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

Step 4: Grill the Mushrooms

Place the marinated mushroom caps on the grill. Reserve some marinade for basting. Grill each side for 5 to 7 minutes until tender while frequently brushing them with marinade.

Step 5: Add Cheese

During the last minute of grilling, top each mushroom cap with sliced Swiss cheese so that it melts perfectly.

Step 6: Grill Onions and Toast Buns

While the mushrooms are cooking, add thick slices of red onion to the grill. Cook them for about 1 minute on each side until slightly charred. Also grill the buns until they are toasted.

Step 7: Assemble Your Burgers

To finish assembling your burgers, place fresh baby spinach on each bun followed by the grilled portobello mushrooms topped with grilled onions, sliced tomato, and avocado. Enjoy your delicious creation!

Common Mistakes to Avoid

When making The Best Grilled Portobello Mushroom Burger, it’s easy to overlook some key steps. Here are common mistakes to watch out for:

• Skipping the Marinade: Not marinating the mushrooms can lead to bland burgers. Always allow the mushrooms to soak in the marinade for at least 20 minutes for maximum flavor.
• Overcooking the Mushrooms: Cooking them too long can make the mushrooms tough. Aim for 5-7 minutes per side while basting with marinade to keep them juicy.
• Ignoring Bun Quality: Using low-quality buns can ruin your burger experience. Opt for whole wheat or artisan buns that hold up well against the toppings.
• Neglecting Toppings: Failing to layer toppings properly can result in a messy burger. Start with spinach, then add grilled mushrooms, onions, tomatoes, and avocado for a balanced bite.
• Not Preheating the Grill: Grilling on a cold surface may cause sticking or uneven cooking. Always preheat your grill or pan before adding the mushrooms.
