To get the right temperature while cooking, you need to preheat your oven to 200 degrees Celsius. This step makes the cooking easier and your mushrooms will be baked properly along with the cheese filling.

After preparing the baking environment, get started with preparing the mushrooms. Clean the mushrooms and remove stems from them. Chop the stems finely using a knife and a cutting board. Keep the mushrooms separately and set aside the stems for further use.

Following with the mushroom preparation, make the filling with the needed ingredients. In a medium-sized bowl, mix the previously shredded mozzarella cheese, minced garlic, chopped stems, parsley, salt, and pepper. Mix together well until they are fully combined and smooth in texture.

Now that your fillings are ready, prepare to stuff them inside the mushrooms. Brush mushroom caps with olive oil and stuff the cheese mixture inside with a spoon.

Your mushrooms are ready to bake. After filling them up, arrange the stuffed mushrooms on a baking sheet. Bake the mushrooms for 20 minutes until they get tender and golden brown.

Let the mushrooms cool down after baking. Keep them at rest for 5 minutes. Garnish with additional chopped parsley, serve, and enjoy!
