Ingredients:
- 16 Medium Cremini (Baby Bella) Mushrooms
- 2 Tbsp Olive Oil
- Pinch of Fine Sea Salt
- Freshly Ground Black Pepper
- The cleaned and finely chopped stems from the 16 mushrooms
- 2 Tbsp Unsalted Butter
- 1/2 cup Finely Diced Shallots
- 2 Cloves Garlic, minced
- 1/2 cup Panko Breadcrumbs
- 1/4 cup Fresh Parsley, finely chopped
- 2 Tbsp Fresh Thyme Leaves
- 1/2 cup Freshly Grated Parmesan Cheese (plus 2 Tbsp for topping)
- 1 Large Egg Yolk, lightly beaten
- 1 tsp Worcestershire Sauce
- 1/4 tsp Red Pepper Flakes
Instructions:
- Gently wipe the mushroom caps clean. Carefully twist or cut the stems off. Finely chop all the stems.
- Preheat oven to 375°F (190°C). Line a large rimmed baking sheet with parchment paper. Arrange the hollowed mushroom caps cavity-side up on the sheet and drizzle lightly with 2 Tbsp olive oil; season with salt and pepper.
- Melt the butter in a medium non-stick skillet over medium heat. Add the chopped mushroom stems and shallots. Sauté for 6–8 minutes until softened and most of the moisture has evaporated.
- Add the minced garlic to the skillet and cook for 1 minute until fragrant. Remove the skillet from the heat and transfer the mixture to a small mixing bowl. Let cool slightly (about 5 minutes).
- Add the breadcrumbs, chopped parsley, thyme, 1/2 cup Parmesan, beaten egg yolk, Worcestershire sauce, and red pepper flakes (if using) to the cooled stem mixture. Mix thoroughly until everything is evenly incorporated.
- Using a small spoon, generously mound the filling mixture into each mushroom cap.
- Sprinkle the remaining 2 Tbsp of Parmesan cheese evenly over the tops of the filled mushrooms.
- Bake for 20–22 minutes, or until the mushrooms are tender and the filling is golden brown and crisp on top. Serve immediately while piping hot.
