Portobello Mushroom Burger Recipe for your Griddle

Portobello mushroom burgers are a fantastic alternative for vegetarians and a delightful choice for anyone who loves the earthy flavor of Portobello mushrooms. Griddling the mushrooms on your griddle creates a wonderful sear and enhances their taste. Here's a recipe for Portobello mushroom burgers:


For the Portobello Mushrooms:

  • 4 large Portobello mushrooms, stems removed
  • 2 tablespoons olive oil
  • 2 cloves garlic, minced
  • 2 tablespoons balsamic vinegar
  • Salt and black pepper, to taste

For the Burger Assembly:

  • Burger buns
  • Sliced cheese (your choice)
  • Fresh lettuce
  • Sliced tomatoes
  • Sliced red onions
  • Condiments (mayonnaise, ketchup, mustard, or your favorites)
  • Optional toppings (avocado, bacon, sautéed onions)


Preparing the Portobello Mushrooms:

  1. Preheat the Griddle:

    • Preheat your griddle to medium-high heat, around 350-375°F (175-190°C).
  2. Marinate the Mushrooms:

    • In a bowl, mix together the olive oil, minced garlic, balsamic vinegar, salt, and black pepper. Brush this mixture onto the Portobello mushrooms on both sides. Allow them to marinate for about 10-15 minutes.
  3. Griddle the Mushrooms:

    • Place the marinated Portobello mushrooms on the hot griddle. Cook them for approximately 5-7 minutes on each side. You want them to be tender and have a nice sear. While cooking, you can baste them with any remaining marinade for extra flavor.

Assembling the Portobello Mushroom Burger:

  1. Prepare the Buns:

    • While the mushrooms are cooking, you can lightly toast the burger buns on the griddle.
  2. Melt the Cheese:

    • In the last minute of cooking, add a slice of cheese to each Portobello mushroom. This will allow the cheese to melt.
  3. Build Your Burger:

    • Lay out a toasted burger bun.
    • Place a lettuce leaf, a slice of tomato, and a few slices of red onion on the bottom bun.
  4. Add the Mushroom:

    • Place a Portobello mushroom on top of the vegetables.
  5. Add Condiments:

    • Add your preferred condiments on top of the mushroom. You can use mayonnaise, ketchup, mustard, or any sauces you like.
  6. Optional Toppings:

    • If you want to customize your burger further, consider adding avocado, bacon, or sautéed onions.
  7. Close the Burger:

    • Top your burger with the other half of the toasted bun.
  8. Serve and Enjoy:

    • Serve your Portobello mushroom burger while it's still warm, and enjoy the wonderful combination of flavors and textures.
