WW Recipe of the Day: Skinny Marinated Portabello “Steaks”
(100 calories | 2 2 2 myWW *SmartPoints value per serving)
Because of their meaty texture, Portabello mushrooms have been compared to “steaks” for years. In this version, all the succulent ingredients that usually make up a steak marinade—like Worcestershire sauce, soy and mustard—are rubbed into mushrooms and then baked or grilled until tender.
These tasty marinated mushrooms are great sliced atop a salad or used as the foundation for a vegetarian WW friendly burger. My beef-loving husband thought they would be perfect on a burger.
With only about 100 calories per large mushroom, hearty appetites may want to double up on the mushrooms, depending on their size, to create a satisfying entree.
As a side dish, 1 meaty mushroom should be sufficient. These mushrooms can be cooked, either on the grill or in the oven.

Grilled Marinated Portabello Mushroom "Steaks"
- 2 tablespoons balsamic vinegar
- 2 teaspoons olive oil
- 1 teaspoons Dijon mustard
- 2 teaspoons low-sodium soy sauce
- 1 teaspoon Worcestershire sauce
- 1 large garlic clove, minced
- 1 teaspoon Montreal Steak Seasoning (or salt & pepper to taste)
- Pinch of cayenne pepper, optional
- 2 large portabello mushrooms, stems removed
- Heat up the grill or preheat the oven to 400F degrees
- If you are going to cook your mushrooms in the oven, line a small baking dish with foil and spray the foil with nonstick spray.
- In a small bowl, stir together the balsamic, olive oil, mustard, soy sauce, Worcestershire sauce, garlic, Montreal steak seasoning (or salt & pepper) and pinch of cayenne (if using) until thoroughly mixed.
- Brush the mushrooms with the mixture and gently "massage" the marinade into the gills and back of the mushrooms. Let sit for 10 minutes to let the marinade absorb.
- Place marinated mushrooms on baking sheet, gills side up, and bake for 15 to 20 minutes, or until soft and slightly bubbly. Alternatively you can grill them gill side up for 5 to 7 minutes and then flip them and continue to cook until tender, 5 to 7 minutes more.
- Remove from oven and cool slightly before serving.
