  • 2 cloves garlic
  • 1/4 cup pine nuts
  • 1/2 cup grated Parmesan cheese
  • 1/2 cup extra-virgin olive oil

  1. Start by making the pesto. In a food processor, combine the fresh basil, garlic, pine nuts, and grated Parmesan cheese. Pulse until finely chopped.
  2. With the food processor running, slowly drizzle in the extra-virgin olive oil until the pesto reaches a smooth, creamy consistency. Season with salt and pepper to taste.
  3. Brush both sides of the Portobello mushrooms with the freshly made pesto, ensuring they are well coated.
  4. Preheat your grill to medium-high heat and lightly oil the grates to prevent sticking.
  5. Place the marinated Portobello mushrooms on the grill and cook for about 4-5 minutes on each side or until they are tender and grill-marked.
  6. Remove the mushrooms from the grill and let them rest for a minute before serving.
