Here is a quick and easy way to prepare those beautiful and meaty portobello mushrooms. The only part that takes a while is the marinating, but you can get other things done in the kitchen while you do it, including preheating the oven. You won’t believe how good this tastes.
This can also be done on an outdoor grill.
Once cooked, the portobellos can be sliced into long strips for a vegetable side dish, a topping for salads and risotto, or a gourmet addition to a toasted sandwich. You can also put the mushroom caps between two hamburger buns to create a new favorite of mine — portobello burgers.
You can play with the proportions for the marinade, but I favor one part red wine vinegar to two parts olive oil.
4 large portobello mushroom caps
1/2 cup red wine vinegar
1 cup olive oil
1 tsp. sugar
1 tsp. salt
1/2 tsp. garlic powder
1/2 tsp. white pepper
Gently rinse the mushrooms and pat dry with a paper towel. Mix the other ingredients together well in a measuring cup, then pour into a large bowl. Add the mushrooms and leave to marinate for about half an hour, turning every so often to make sure all sides can sit in the liquid.
Preheat the broiler (I set it to 225C/460F degrees). When the broiler is ready, place the caps rounded side up on a baking tray.
Broil for 2-3 minutes, then turn and cook for a further 4-5 minutes. Remove and serve immediately.
