Ingredients

Ingredients:
– 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)

How to Make The Best Grilled Portobello Mushroom Burger

Step 1: Prepare the Marinade

In a large bowl, whisk together the following ingredients until well combined:
1. Balsamic vinegar
2. Low sodium soy sauce
3. Olive oil
4. Chopped rosemary
5. Steak seasoning

Step 2: Marinate the Mushrooms

Place the mushroom caps in the bowl with the marinade and toss them until evenly coated. Let them stand at room temperature for about 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 it with cooking spray to prevent sticking.

Step 4: Grill the Mushrooms

Carefully place the marinated mushrooms on the grill, reserving some marinade for basting. Grill each side for about 5 to 7 minutes until tender, brushing frequently with the reserved marinade.

Step 5: Add Cheese

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

Step 6: Grill Onions and Buns

While your mushrooms are cooking, grill thick slices of red onion for about one minute on each side until they are slightly charred. Also, toast your whole wheat buns on the grill until golden brown.

Step 7: Assemble Your Burger

To assemble your burgers, start by placing baby spinach on each toasted bun. Then add the grilled portobello mushrooms topped with melted Swiss cheese. Finish with grilled onions, sliced tomatoes, and avocado before closing your burger with the other half of the bun.

Enjoy your delicious creation!
