If you ask me, stuffed mushrooms are one of the best party appetizers around.
These breadcrumb stuffed mushrooms make an easy snack that’s packed with savory goodness. The buttery mushroom caps get filled with seasoned breadcrumbs and herbs, creating that perfect crispy-tender bite.
They’re topped with melted cheese and baked until golden brown, making them impossible to resist. The simple ingredients work together to create something that tastes way fancier than it actually is.
It’s a crowd-pleasing appetizer that works for any occasion, from game day gatherings to holiday parties.

What Kind of Mushrooms Should I Use?
For stuffed mushrooms, white button or cremini mushrooms are your best bet since they have the perfect cup-like shape to hold all that tasty filling. These mushrooms typically come in packages at the grocery store, and you’ll want to look for ones that are about 2-3 inches wide – not too small that they’re fussy to fill, but not so large that they’ll take forever to cook. When you’re shopping, pick mushrooms that feel firm and have a fresh, clean smell, avoiding any that are slimy or have dark spots. Just remember to pop out the stems (you can chop these up and add them to your filling) and give the caps a quick wipe with a damp paper towel instead of washing them under running water, since mushrooms act like little sponges and can get waterlogged.
Options for Substitutions
This simple appetizer recipe can be adapted with several easy swaps if you need to make changes:
- Mushroom caps: While button mushrooms are common, you can use cremini, baby portobello, or even larger portobello caps (just increase cooking time for bigger mushrooms).
- Fresh breadcrumbs: No fresh breadcrumbs? Use panko for a crunchier texture, or regular dried breadcrumbs (reduce the amount by 1/3 since they’re more compact).
- Fresh parsley: You can swap parsley with other fresh herbs like basil, thyme, or oregano. If using dried herbs, use 1/3 of the amount called for fresh.
- Pecorino Romano: Parmesan makes a great substitute, or try Asiago for a similar sharp, salty flavor. For a milder taste, use Grana Padano.
- Olive oil: Any neutral cooking oil works here, like vegetable or canola oil. Melted butter is also a tasty alternative.
- Garlic: Fresh garlic is best, but in a pinch, use garlic powder (¼ teaspoon equals 1 clove) or pre-minced garlic from a jar.
Watch Out for These Mistakes While Cooking
The biggest challenge when making stuffed mushrooms is dealing with excess moisture – make sure to thoroughly clean your mushroom caps but avoid soaking them in water, as they act like tiny sponges and can become waterlogged. A quick wipe with a damp paper towel is all you need.
Another common mistake is not pre-cooking the mushroom caps before stuffing – giving them a quick 5-minute roast upside down helps release their natural moisture and prevents a soggy final result.
The breadcrumb filling can easily become too dry, so drizzle just enough olive oil to help it stick together without becoming dense or paste-like, and don’t skip scraping out the mushroom stems and gills, as leaving them in can make the final dish bitter and muddy-looking.
For the crispiest topping, avoid pressing the breadcrumb mixture too firmly into the caps – a light, loose filling will brown better and create a more pleasant texture.
What to Serve With Stuffed Mushrooms?
These stuffed mushrooms work perfectly as both an appetizer or a side dish, making them super flexible for any meal plan! When I serve them as a main course, I like to pair them with a simple green salad dressed with lemon vinaigrette and a side of quinoa or rice to soak up all those tasty mushroom juices. For a party spread, they fit right in alongside other finger foods like bruschetta, cheese plates, or antipasto platters. Since these mushrooms have an Italian flair with the Pecorino Romano, they also go really well with pasta dishes or alongside grilled chicken or fish.
Storage Instructions
Keep Fresh: These stuffed mushrooms are best enjoyed right away, but if you have leftovers, place them in an airtight container in the fridge for up to 2 days. The breadcrumb filling might get a bit softer over time, but they’ll still taste good!
Make Ahead: Want to prep these in advance? You can stuff the mushrooms and keep them uncooked in the fridge for up to 24 hours. Just cover them well with plastic wrap, then pop them in the oven when you’re ready to serve. This is super handy when you’re planning a party!
Warm Up: To enjoy leftover stuffed mushrooms, place them in a preheated oven at 350°F for about 10 minutes until they’re heated through. The microwave works too, but the breadcrumbs won’t be as crispy. A quick zap for 30 seconds should do the trick if you’re in a hurry.

Ingredients
- Mushroom caps
- Fresh breadcrumbs
- Fresh parsley
- Garlic
- Olive oil
- Salt
- Pepper
- Pecorino romano cheese
Step 1: Prepare the Oven and Mushrooms
Start by preheating your oven to 400°F (200°C).
While the oven is heating, clean the mushroom caps by removing the stems and hollowing out the insides to create a pocket for the filling.
Finely chop the removed mushroom stems and set them aside for later use.
Step 2: Make the Breadcrumb Mixture
Prepare fresh breadcrumbs by cutting the crusts off a couple of slices of Italian bread.
Pulse them in a food processor until fine, or alternatively, chop them finely with a knife.
In a bowl, combine the chopped mushroom stems, prepared breadcrumbs, and a generous amount of finely chopped fresh parsley.
Grate in a good amount of Parmesan cheese using a microplane, then grate in some garlic until finely minced.
Step 3: Season the Filling
Drizzle about 3 to 4 tablespoons of olive oil over the breadcrumb mixture.
Season with salt and pepper.
Mix everything until the filling is moistened but not soggy, ensuring all ingredients are evenly distributed.
Step 4: Prepare the Mushroom Caps
Line a baking dish with aluminum foil and place the cleaned mushroom caps in it.
Drizzle olive oil over the mushrooms to coat the bottoms and sides lightly.
This will help them bake perfectly without sticking.
Step 5: Fill and Bake the Mushrooms
Fill each mushroom cap with the breadcrumb mixture, packing it in well to ensure it stays in place during baking.
Drizzle a little more olive oil over the top of the filled mushrooms for extra flavor and crunch.
Bake the mushrooms in the preheated oven for 20 to 25 minutes, or until the tops are crisp and golden brown.
Step 6: Cool and Serve
Once baked, allow the stuffed mushrooms to cool for about 5 minutes before serving.
This brief cooling period helps set the filling and makes them easier to handle.
Enjoy your delicious, savory stuffed mushrooms!
