Those big, juicy-looking portobello mushrooms at the market are fantastic when they're simply broiled or grilled. They can be eaten on their own or act as a patty for a vegetarian alternative to the hamburger. Either way, this recipe is quick and easy. 

Large portobellos are meaty and filling. For the broiler, all they need is a marinade of garlic, olive oil, vegetable broth, and balsamic vinegar. Most of your time will be spent waiting for them to marinate. After that, it takes just a few minutes on each side to grill them to perfection. This same recipe can be used on your outdoor grill if you feel like cooking out.

Ingredients

  • 4 large portobello mushrooms, wiped clean and stemmed

  • 1 tablespoon olive oil

  • 1 tablespoon vegetable or chicken broth

  • 1/4 cup balsamic vinegar

  • 2 cloves garlic, crushed

Steps to Make It

  1. Gather the ingredients.

  2. Place mushrooms in a large bowl.

  3. In a small bowl, whisk together olive oil, vinegar, broth, and garlic. Pour over portobello mushrooms, cover bowl, and marinate for 15 to 30 minutes.

  4. Preheat broiler.

  5. Place mushrooms on a broiler pan coated with nonstick cooking spray. Broil 6 inches from broiler for 5 to 7 minutes on each side.

Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat-resistant, tempered glass products can, and do, break occasionally.

Serving Suggestions

You have many options when it comes to enjoying your broiled mushrooms. Serve them on their own and eat just as you would a steak along with a green salad for a well-rounded vegetarian meal. Grilled or steamed asparagus, cooked carrots, and rice make excellent side dishes as well.

The mushrooms are also quite delicious in a whole-grain bun or when served in a pita with your favorite toppings. Tomatoes, onions, pickles, avocado, and melted cheese are all excellent ways to dress up the sandwich. Add a spicy mayonnaise or your favorite mustard; anything you would normally add to a burger will work.
