Ingredients
  

For the Mushroom Caps:
  • - 6 large Portobello mushrooms wiped clean, stems removed, gills scraped out
  • - 2 tbsp extra virgin olive oil for brushing
  • - 1 pinch salt to taste
  • - 1 pinch freshly cracked black pepper to taste
For the Garlic Herb Crumble Filling:
  • - 0.5 cup Panko breadcrumbs for optimal texture
  • - 0.33 cup Parmesan cheese finely grated
  • - 4-5 cloves garlic finely minced
  • - 2 tbsp fresh Italian parsley finely chopped
  • - 1 tbsp fresh basil or green onion finely minced
  • - 1 tsp Italian seasoning blend dried
  • - 1 tbsp extra virgin olive oil to moisten the mixture
For the Topping & Garnish:
  • - 1 cup cherry or grape tomatoes sliced into neat rounds
  • - 1 tbsp fresh parsley sprigs finely chopped for final garnish

Method
 

Prep the Oven & Pan:
  1. Preheat your oven to 375°F (190°C) and line a large, rimmed baking sheet with parchment paper or aluminum foil.
Clean the Mushrooms:
  1. Wipe down the portobello caps using a damp paper towel to clean away debris. Pop off the stems, then use a spoon to gently scrape out the dark interior gills.
Season the Bases:
  1. Arrange the hollowed caps on your baking sheet with the open side facing up. Lightly brush the inside and outside of each cap with olive oil, then season the interiors with a small pinch of salt and pepper.
Mix the Stuffing:
  1. In a medium bowl, combine the Panko breadcrumbs, grated Parmesan cheese, minced garlic, chopped parsley, minced basil, and dry Italian seasoning. Drizzle in 1 tablespoon of olive oil and stir with a fork until it resembles wet sand.
Stuff the Caps:
  1. Spoon the crumb filling evenly into the center of each portobello mushroom, pressing down gently to anchor it.
Layer the Tomatoes:
  1. Neatly place 2 to 3 slices of cherry tomato rounds flat on top of the breadcrumb stuffing for each mushroom.
Bake to Perfection:
  1. Slide into the oven and bake for 15 to 20 minutes until the mushrooms are tender, the crumbs are crisp and golden brown, and the tomatoes are blistered.
Garnish & Serve:
  1. Let rest for 2-3 minutes out of the oven. Top with a final sprinkle of fresh chopped parsley and serve warm.

Notes

* Never wash portobellos directly under running water as they act like sponges and will turn soggy during baking. Always use a damp paper towel to wipe them clean.
* To make this recipe vegan, replace the traditional dairy Parmesan cheese with an equal amount of nutritional yeast or plant-based parmesan alternative.
* Leftovers can be stored top-side-up in an airtight glass container in the refrigerator for up to 3-4 days. Reheat at 350°F (175°C) in an oven or air fryer to maintain a crispy crumb topping. Freezing is not recommended.
