Blue Cheese Portobello Burgers
Blue cheese and slow-cooked onions turn a grilled portobello into an indulgent portobello burger. Ruby port—a sweet fortified wine—gives extra depth of flavor to the caramelized onions.
- 3 tablespoons extra-virgin olive oil, divided
- 1 tablespoon balsamic vinegar
- 3 cloves garlic, minced
- 4 large portobello mushrooms, stems removed
- 3 cups thinly sliced red onion
- 2 tablespoons water
- 1/4 cup ruby port
- 1/2 teaspoon salt, divided
- 1/4 teaspoon freshly ground pepper, divided
- 1/2 cup crumbled reduced-fat blue cheese (2 ounces)
- 4 whole-wheat hamburger buns
- 1 cup baby arugula
- 4 thick slices tomato
- Whisk 2 tablespoons oil, vinegar and garlic in a bowl. Brush the mixture all over mushrooms and let stand for 30 minutes.
- Meanwhile, heat the remaining 1 tablespoon oil in a large skillet over high heat. Add onion and cook, stirring frequently, until beginning to brown, about 5 minutes. Reduce heat to low, add water and cook, stirring frequently, until the onion is browned and very soft, about 15 minutes. Add port; cook, stirring occasionally, until mostly evaporated, about 3 minutes more. Stir in 1/4 teaspoon salt and 1/8 teaspoon pepper. Remove from the heat and cover.
- Preheat grill to medium.
- Sprinkle the mushrooms with the remaining 1/4 teaspoon salt and 1/8 teaspoon pepper. Grill, gill-side down, for 5 minutes. Turn over and top each with 2 tablespoons cheese. Grill until the mushrooms are tender, 4 to 5 minutes more.
- Toast buns. Divide the onions among the mushrooms. Serve (cheese-side up) on buns with arugula and tomato.
