Grilled Portabella Mushrooms With Balsamic Marinade

Submitted by groovyrooby

"I've used this recipe for years....unfortunately I've forgotten the original source. It's a great dish to offer at a barbecue instead of the same tired old veggie burger. The marinade is very tart and makes a lovely grilled portabella sandwich, but it would also be delicious sliced and placed on top of a nice leafy green salad. I'm posting the recipe as copied onto a piece of paper years ago, but you'll notice the dressing instructions are incomplete - sorry! I usually just grill or broil these and eat them on a bun with some red onion, lettuce, and Vegenaise (vegan mayo), if available."

 

• Ready In: 20mins
• Ingredients: 15
• Yields: 6 sandwiches
• Serves: 6

ingredients

• MARINADE

• 1 cup balsamic vinegar
• 2 tablespoons olive oil
• 1 teaspoon dried basil
• 1⁄4 teaspoon kosher salt
• 1⁄4 teaspoon white pepper (I just use freshly ground black pepper)
• 2 garlic cloves, minced
• 6 portabella mushroom caps (about 1 1/2 lbs.)
• cooking spray

• DRESSING

• 1 tablespoon olive oil
• 1 1⁄2 cups sliced onions
• 1⁄4 cup mayonnaise
• 1 teaspoon bottled minced roasted garlic
• 6 whole wheat kaiser rolls or 6 hamburger buns
• 6 curly lettuce leaves
• 6 slices tomatoes

directions

1. Combine first 6 ingredients in a large zip-top plastic bag. Add caps to the marinade. Seal and marinate in fridge up to 24 hours.
2. Prepare grill or broiler.
3. Remove caps and discard marinade. Place caps on grill rack or broiler coated with spray. Cook 5 minutes or until tender.
4. Heat oil over medium-high heat. Add onion. Cover and cook ten minutes or until golden, stirring frequently. (at this point I assume you mix the onions and garlic into the mayo, but I've never actually used this step).
5. Assemble grilled portabella sandwiches with one cap per bun, plus any lettuce, mayo, tomato, onion, or other garnish that you like. Or slice the portabellas into strips and enjoy as a topping for a mixed green salad with onion, tomato, etc.

Delish marinade. I did not try the dressing and just ate it straight up. Will def. try the dressing the next time I do these. Thanks for the keeper recipe!

The marinade was lovely, enjoyed every bite. I didn't try the dressing but since the first part was so good I may try the dressing at some point. I know I'll make this again.
