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)

For Garnish

• 2 tablespoons fresh parsley, finely chopped

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 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 to ensure they are evenly coated. Allow them to stand 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. Once hot, brush the grate with oil or lightly spray the grill pan to prevent sticking.

Step 4: Grill the Mushrooms

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

Step 5: Add Cheese

During the last minute of cooking, top each grilled mushroom cap with a slice of Swiss cheese. Allow it to melt slightly before removing from heat.

Step 6: Grill Onions and Buns

While your mushrooms are grilling, add thick slices of red onion to the grill. Cook for around 1 minute on each side until slightly charred. Also grill your whole wheat buns until toasted.

Step 7: Assemble Your Burgers

To finish assembling your burgers, place baby spinach on each toasted bun. Add a grilled portobello mushroom cap topped with melted cheese. Finish by layering on grilled onions, sliced tomatoes, and avocado before serving.

Enjoy crafting these delicious burgers that will surely impress everyone at your table!

Common Mistakes to Avoid

When making The Best Grilled Portobello Mushroom Burger, it’s easy to run into some common pitfalls. Here are a few mistakes to avoid for the perfect burger.

• Skipping the Marinade: Not marinating the mushrooms can lead to bland flavors. Always allow your mushrooms to soak in the marinade for at least 20 minutes for maximum taste.

• Overcooking the Mushrooms: Cooking them too long can make the mushrooms tough. Grill until they are tender, usually about 5 to 7 minutes per side.

• Choosing the Wrong Cheese: Using a cheese that doesn’t melt well can ruin your burger. Opt for Swiss or another melting cheese for a gooey topping that complements the mushrooms perfectly.

• Neglecting Toasted Buns: Serving on un-toasted buns can result in a soggy bottom. Always grill or toast your buns for added texture and flavor.

• Forgetting Fresh Ingredients: Skipping fresh toppings like spinach and avocado can make your burger less appealing. Always add fresh veggies to enhance taste and nutrition.
