Ingredients

• 16 pieces large button mushrooms
• 2 tablespoons butter
• 1 medium, finely chopped yellow onion
• 2 minced garlic cloves
• 4 ounces cream cheese, softened
• 1 cup sharp cheddar cheese, shredded
• 0.25 cup Parmesan cheese, grated
• 0.25 cup breadcrumbs
• 1 tablespoon fresh parsley, chopped
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 1 teaspoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a baking sheet with nonstick spray or a thin coat of oil.

Step 2

Clean the mushrooms with a damp paper towel and gently remove the stems. Save the stems for the filling by finely chopping them.

Step 3

Heat the butter in a skillet over medium heat. Add the chopped mushroom stems, diced onion, and minced garlic. Cook for 5-7 minutes until softened and fragrant, stirring occasionally.

Step 4

Remove the skillet from heat and let the mixture cool slightly. In a mixing bowl, combine the cooked onion mixture with cream cheese, shredded cheddar cheese, Parmesan cheese, breadcrumbs, parsley, salt, and black pepper. Mix well until combined.

Step 5

Using a small spoon, carefully fill each mushroom cap with the cheesy onion mixture, slightly mounding the filling on top.

Step 6

Place the stuffed mushrooms onto the prepared baking sheet, ensuring they are spaced slightly apart. Drizzle a thin thread of olive oil over the mushrooms for a golden finish.

Step 7

Bake in the preheated oven for 20-25 minutes or until the mushrooms are tender, and the top is golden and bubbly.

Step 8

Remove from the oven and let the mushrooms cool for 5 minutes before serving. Garnish with additional parsley if desired and serve warm.
