- 4 cloves garlic, minced: Fresh garlic enhances the dish with its aromatic goodness.
- 2 tablespoons olive oil: Extra virgin olive oil offers the best flavor and health benefits.
For the Caramelized Onions
- 2 large onions, thinly sliced: Sweet onions like Vidalia work fabulously for caramelization.

How to Prepare This Recipe
Step 1: Prepare the Ingredients
Preheat your oven to 375°F (190°C). Clean the mushrooms gently with a damp cloth to remove any dirt. Carefully remove the stems and set aside the caps for stuffing.
Step 2: Caramelize the Onions
In a large skillet, melt 1 tablespoon of butter over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring often, for about 20-25 minutes until the onions are golden brown and tender. Lower the heat if they start to brown too quickly. Once done, remove from heat and set aside.
Step 3: Make the Filling
In a mixing bowl, combine the mushroom stems, garlic, caramelized onions, and 1 cup of grated Parmesan cheese. Incorporate 2 tablespoons of olive oil and mix well until all ingredients are evenly distributed.
Step 4: Stuff the Mushrooms
Take each mushroom cap and fill it generously with the prepared stuffing. Press down lightly to ensure the filling adheres well.
Step 5: Bake
Place the stuffed mushrooms on a baking sheet lined with parchment paper. Bake for about 25-30 minutes, or until the mushrooms are tender and the tops are golden and bubbly.
Step 6: Serve
Once removed from the oven, allow them to cool for a few minutes. Garnish with fresh parsley for an added touch of freshness, and serve warm.
