The hearty flavor and meaty texture of portobello mushrooms make them the perfect choice for a flavorful, satisfying burger.

Balsamic-Glazed Portobello Burgers

Topped with sautéed onions and melted blue cheese, these portobello burgers are delicious enough to satisfy even the most die-hard beef lover.

The balsamic vinegar glaze adds a subtle, sweet and savory quality that serves as a nice contrast to the tangy blue cheese.

Our portobello burger recipe includes easy instructions for making the balsamic glaze (reduction) yourself and it only takes a few minutes, but you can also buy it bottled in just about any supermarket.

We think it’s a terrific condiment to have on hand because it gives a nice flavor boost to all sorts of foods.

In addition to glazing these portobello burgers, we drizzle balsamic glaze on vegetables like zucchini and bell peppers before roasting them, brush it onto grilled steak and chicken, and use it as an easy topping for meatloaf.

Another way to use balsamic reduction is to combine it with tomatoes and pasta. Our recipe for Balsamic and Sun-Dried Tomato Conchiglie is a simple side dish that really shows off this unique blend of flavors.

Topped with sautéed onions and blue cheese, these balsamic-glazed portobello burgers are a deliciously satisfying alternative to ground beef.

Ingredients

  • 6 portobello mushrooms
  • 1/2 cup balsamic vinegar
  • 2 tablespoons vegetable oil
  • 2 large sweet onions, thinly sliced
  • Salt and freshly ground black pepper
  • Pinch of sugar
  • 6 ounces crumbled blue cheese
  • 6 soft sandwich rolls

Instructions

  1. Brush any dirt from the mushroom caps, remove the stems and reserve them for another use.
  2. Place the balsamic vinegar in a small saucepan and bring to a simmer over medium-high heat.
  3. Immediately reduce the heat to medium and continue cooking, stirring occasionally, until the vinegar is reduced by about half, 5 to 6 minutes.
  4. Remove from the heat and set aside to cool for 10 minutes.
  5. Use about half of the reduction to brush the tops of the mushrooms, then set them aside while you sauté the onions.
  6. Separate the onions into rounds. Heat the oil in a large skillet over medium heat. Add the onions, season with salt, pepper and a pinch of sugar.
  7. Sauté until the onions are soft, translucent and beginning to brown, 5 to 7 minutes.
  8. Preheat a gas or charcoal grill to a medium temperature (about 400°F).
  9. Oil the grates and add the mushrooms, gill side up.
  10. Grill for 3 minutes, then turn them over, brush with the rest of the balsamic reduction and grill until tender, about 3 minutes longer.
  11. Top each mushroom with a portion of blue cheese and cook just until the cheese begins to melt, 1 minute more.
  12. To serve, place a portion of onions on the bottom of each bun, add a cheese-topped portobello and serve immediately.
