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. Source: EatingWell Magazine, May/June 2012

Ingredient Checklist


Instructions Checklist
  • 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.

We made this a few nights ago. They were ok but not great. They were made to the recipe which wasn't difficult or time consuming and they turned out fine but just didn't "wow" us like thought they would. I don't know if we'll make them again because there are so many other recipe's we want to try! Read More
