Ingredients

Scale

Mushrooms and Filling

  • 1 lb small and firm cremini or button mushrooms (smaller mushrooms work best)
  • 1 tbsp butter
  • ½ small yellow onion, minced
  • Leaves from 1 small sprig of thyme, chopped
  • Freshly cracked black pepper, to taste
  • 1 (5.2 oz) package of garlic and herb Boursin cheese, softened to room temperature

Topping and Garnish

  • ¼ cup panko crumbs
  • 2 tbsp fresh parmesan, finely grated
  • 1 tbsp fresh parsley, finely chopped
  • 1 tbsp olive oil

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it’s ready to bake the mushrooms evenly.
  2. Prepare Mushrooms: Remove the stems from the mushroom caps carefully and set the caps aside. Finely mince the mushroom stems for the filling mixture.
  3. Sauté Mushroom Stems and Aromatics: Heat the butter in a skillet over medium heat. Add the minced mushroom stems, minced onion, and chopped thyme leaves. Cook for 5-7 minutes until the mixture is golden brown and the onions are slightly caramelized. Season with freshly cracked black pepper to taste. Remove from heat and let it cool.
  4. Mix Toppings: In a small bowl, combine the panko crumbs, grated parmesan cheese, and chopped fresh parsley. Stir well to integrate all ingredients.
  5. Prepare Cheese Mixture: In a separate bowl, blend the softened garlic and herb Boursin cheese with the cooled mushroom and onion mixture. Once combined, stir in half of the panko topping mixture to add texture and flavor.
  6. Coat Mushroom Caps: Drizzle the mushroom caps evenly with olive oil to help them roast nicely and maintain moisture during baking.
  7. Stuff Mushrooms: Spoon the Boursin cheese mixture generously into each mushroom cap. Then, dip the tops of the stuffed mushrooms into the remaining panko mixture to create an extra crunchy and flavorful crust.
  8. Bake: Arrange the stuffed mushrooms on a baking sheet in a single layer. Bake in the preheated oven for 20 minutes, or until the mushrooms are tender and the cheese filling is hot and gooey.
  9. Optional Broil for Crispiness: For a golden and crunchier topping, broil the mushrooms for an additional 1-2 minutes, watching carefully to avoid burning.

Notes

  • Use smaller mushrooms for the best bite-sized appetizers and even cooking.
  • Make sure the Boursin cheese is softened to room temperature for easier mixing and a creamier filling.
  • The broil step is optional but recommended if you like a golden, crispy topping.
  • You can prep the stuffing mixture ahead of time and refrigerate before filling and baking.
  • Serving suggestion: pair with a crisp white wine or sparkling beverage for a perfect appetizer experience.
