What Are Stuffed Mushrooms?
Stuffed mushrooms are a classic appetizer made by removing the mushroom stems and filling the caps with a flavorful mixture. In this recipe, we use a combination of stale bread, Parmesan, parsley, and garlic to create a savory filling that perfectly complements the tender mushrooms.
Cooking Tips
- If you don’t have stale bread, you can use fresh bread, but be sure to dry it out in the oven for a few minutes first.
- Add a sprinkle of red pepper flakes to the filling for a bit of heat.
- You can also use other herbs like thyme or oregano to customize the flavor.
Frequently Asked Questions
Can I use other types of mushrooms?

How can I make this recipe ahead of time?
You can prepare the stuffed mushrooms a day before and store them in the fridge. Just bake them fresh when you’re ready to serve.
Can I make them vegan?

How to Store
Store any leftover stuffed mushrooms in an airtight container in the fridge for up to 3 days. Reheat in the oven for a few minutes to restore their crispy texture.
