Build Stuffed Mushrooms w/ Parmesan & Thyme Step by Step

Creating Stuffed Mushrooms w/ Parmesan & Thyme is a straightforward process. Follow these steps for a delicious result:
Step 1: Preheat Your Oven
Preheat your oven to 375°F (190°C). This ensures that your mushrooms will cook evenly and achieve that lovely golden color.
Step 2: Prepare the Mushrooms
Gently clean the button mushrooms with a damp cloth to remove any dirt. Carefully remove the stems from the mushrooms and set them aside. You want the caps to be intact for stuffing.
Step 3: Chop the Fillings
Finely chop the mushroom stems, onion, and garlic. You will want to ensure these are small enough to fit nicely into the mushroom caps.
Step 4: Sauté the Mixture
In a skillet over medium heat, melt the butter. Add the chopped onion and garlic, cooking until they are soft and fragrant. Stir in the chopped mushroom stems and fresh thyme, cooking for an additional 3-4 minutes.
Step 5: Combine the Filling
In a mixing bowl, combine the sautéed mixture with bread crumbs and grated Parmesan cheese. Season with a pinch of sea salt and a few cracks of pepper from the grinder. Mix until everything is well incorporated.
Step 6: Stuff the Mushrooms
Using a spoon, fill each mushroom cap with the prepared filling, pressing down gently to ensure they are well packed.
Step 7: Arrange & Drizzle
Place the stuffed mushrooms in a baking dish. Drizzle a little extra virgin olive oil over them for added flavor and moisture.
Step 8: Bake
Bake in the preheated oven for about 20-25 minutes or until the tops are golden brown and the mushrooms are tender.
Step 9: Serve Warm
Remove the mushrooms from the oven and allow them to cool slightly before serving. Enjoy them warm for the best flavor experience!
Flavor-Forward Alternatives

Want to switch things up? Here are some ideas for alternative ingredients that can elevate your Stuffed Mushrooms w/ Parmesan & Thyme:
- Cheese Variations: Try using feta or goat cheese for a tangier flavor.
- Herb Swaps: Experiment with basil or oregano instead of thyme.
- Nuts: Add finely chopped walnuts or pine nuts for a delightful crunch.
- Spice it Up: Incorporate red pepper flakes for some heat.
Don’t Do This
To ensure your Stuffed Mushrooms w/ Parmesan & Thyme turn out perfectly, avoid these common mistakes:
- Don’t overcrowd the baking dish; give each mushroom enough space to cook evenly.
- Don’t skip the seasoning; a little salt and pepper enhance the flavors significantly.
- Don’t overstuff the mushrooms; they should be filled but not overflowing, or they may fall apart.
- Don’t use dried herbs if fresh are available; fresh thyme provides a vibrant flavor that dried cannot match.
Cooling, Storing & Rewarming
If you have leftovers (which is rare because they’re so delicious!), here’s how to handle them:
Allow the stuffed mushrooms to cool completely before transferring them to an airtight container. They can be stored in the refrigerator for up to 3 days. To rewarm, simply place them in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through.
