Ingredients

  • 4 large portobello mushrooms, stems removed
  • 2 tablespoons olive oil
  • Sea salt and black pepper, to taste
  • 12 ounces chicken breasts, cooked and shredded
  • 1/2 cup pesto, plus more for garnish
  • 1/2 cup diced roasted red peppers
  • 1 small red onion, diced
  • 2 cloves garlic, minced
  • 1 cup shredded mozzarella cheese
  • 1/4 cup finely grated parmesan cheese, for garnish
  • 4 basil leaves, chiffonade, for garnish
  • Pinch of red pepper flakes, for garnish

Instructions

  1. Preheat the oven to 400°F. Line a baking sheet with parchment paper or a silicone baking mat.
  2. Remove the stems from the mushroom caps and slice a thin layer off the tops so they sit flat. Reserve the trimmed mushroom pieces.
  3. Remove the mushroom gills, brush the caps with olive oil, and season with salt and pepper. Bake for 12 minutes.
  4. Finely chop the reserved mushroom stem and cap pieces.
  5. In a large bowl, combine the chopped mushroom pieces, shredded chicken, pesto, roasted red peppers, onion, garlic, and 1/2 cup of the mozzarella cheese.
  6. Divide the filling evenly among the mushroom caps and top with the remaining mozzarella cheese.
  7. Bake for an additional 7 minutes at 400°F, then broil on high for 2 to 3 minutes until the cheese is golden brown and bubbling.
  8. Drizzle additional pesto over each mushroom and garnish with parmesan cheese, basil, and red pepper flakes before serving.

Notes

  • Use rotisserie chicken for a quick shortcut.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • Swap mozzarella for provolone or fontina cheese for a different flavor.
  • Serve with a side salad or roasted vegetables for a complete meal.
