Portobello Mushroom Burger

Meaty marinated portobello caps grilled until tender and smoky, layered with roasted red pepper, peppery arugula, and herbed goat cheese on a toasted bun. A vegetarian burger that carnivores actually crave.

⏱ 30 minServes 4American

Ingredients

  • 4 large portobello mushroom caps, stems removed
  • 3 tbsp olive oil
  • 2 tbsp balsamic vinegar
  • 1 tbsp soy sauce
  • 2 cloves garlic, minced
  • 1/2 tsp dried thyme
  • 1/2 tsp black pepper
  • 1/2 cup roasted red peppers from a jar, drained
  • 100 g soft goat cheese (chèvre)
  • 2 tbsp fresh chives, finely chopped
  • 1 cup arugula
  • 4 ciabatta buns or burger buns
  • 2 tbsp mayonnaise

Directions

  1. 1Whisk together olive oil, balsamic vinegar, soy sauce, garlic, thyme, and pepper in a shallow dish.
  2. 2Add portobello caps gill-side up and spoon marinade over them; let sit 10 minutes.
  3. 3Preheat grill or grill pan to medium-high heat and lightly oil the grates.
  4. 4Grill mushrooms gill-side down 4–5 minutes, flip, and grill another 4–5 minutes until tender and juicy.
  5. 5Meanwhile, mash goat cheese with chives until smooth and spreadable.
  6. 6Toast buns cut-side down on the grill for 1–2 minutes.
  7. 7Spread mayonnaise on bottom bun and herbed goat cheese on top bun, then layer arugula, mushroom cap, and roasted red pepper; press together and serve.

💡 If goat cheese isn't available, cream cheese mixed with a pinch of garlic powder and herbs works well. Pat mushrooms dry before marinating if they seem very wet — excess moisture causes steaming rather than grilling.
