Best Vegetarian Stuffed Mushrooms

Preparing the Mushrooms

1. Preheat your oven to 375°F (190°C).
2. Clean the mushrooms gently with a damp cloth to remove any dirt.
3. Remove the stems from the mushrooms, finely chop them, and set them aside. You'll use them in the filling.

Preparing the Filling

1. In a large skillet, heat the olive oil over medium heat.
2. Add the chopped shallot and sauté for about 5 minutes until they become soft and translucent.
3. Add the pine nuts and mushroom stems to the skillet. 
4. Cook for another 2-3 minutes until the pine nuts are lightly toasted and the mushroom stems are cooked.
5. Stir in the fresh thyme, garlic, chopped parsley, and breadcrumbs. Cook for an additional minute until the breadcrumbs are lightly toasted.
6. Remove the skillet from the heat and stir in the grated parmesan cheese, salt, and black pepper. Mix everything well.

Stuffing and Baking the Mushrooms

1. Place the cleaned mushrooms on a baking sheet, cap side down.
2. Stuff each mushroom cap generously with the filling mixture, pressing it down slightly to pack it in.
3. Top each stuffed mushroom with a few small cubes of butter.
4. Sprinkle the grated cheddar cheese evenly over the stuffed mushrooms.
5. Bake in the preheated oven for about 15-20 minutes or until the mushrooms are tender, and the cheese is melted and bubbly. The exact cooking time may vary depending on the size of your mushrooms, so keep an eye on them.
6. Once the mushrooms are done, remove them from the oven and let them cool for a few minutes.
