Olive Garden Stuffed Mushrooms with Sausage and Cheese
These mushrooms are the appetizer you remember, the one that disappears from the plate before you even sit down. A savory Italian sausage filling tucked into tender caps, all topped with melty cheese and baked until the edges crisp up. They come together in about 30 minutes and work every single time, no tricky steps.

Why This Copycat Recipe Just Works
The filling hits that salty, herby, garlicky note with a soft crumb from the breadcrumbs and a little stretch from mozzarella. It stays moist inside the mushroom without turning the cap soggy.
I’ve made these for holiday spreads and quick weeknight snacks, and they always finish first. You can prep them ahead and bake when your guests walk in, warm and bubbly from the oven.
Ingredients

- 16 medium cremini mushrooms (about 1½ lbs): look for caps with a deep bowl shape to hold more filling
- ½ lb mild or hot Italian sausage, casings removed: bulk sausage works too
- 2 tbsp unsalted butter: for sautéing the stems and garlic
- 2 cloves garlic, minced
- ¼ cup finely chopped mushroom stems: reserved from the caps; don’t waste them
- ¼ cup plain breadcrumbs: panko or regular both work, panko gives a lighter crunch
- ¼ cup grated Parmesan cheese
- ¼ cup shredded low-moisture mozzarella cheese: whole-milk mozzarella melts creamiest
- 2 tbsp chopped fresh parsley: plus a little extra for finishing
- Salt and black pepper: to season after mixing
Variations and Easy Swaps
- Sausage swap: use ground chicken or turkey sausage for a leaner filling. The mixture will be less fatty, so stir in an extra teaspoon of butter to keep it from drying out.
- Cheese twist: trade mozzarella for provolone or fontina if you want a sharper, nuttier melt. Keep the Parmesan in for salt.
- Gluten-free: substitute plain gluten-free breadcrumbs. The filling will still hold together.
- Herb boost: add ½ tsp dried oregano or a pinch of red pepper flakes when you cook the sausage for more heat and Italian flavor.

How to Make Olive Garden Stuffed Mushrooms
Step 1: Clean and Prep the Mushrooms

Wipe the mushrooms clean with a damp paper towel. Never rinse them under water or they’ll soak up moisture and steam instead of roast. Pop the stems out with a gentle twist and set the caps aside. Finely chop enough stems to measure ¼ cup, saving the rest for another use.
The caps should feel dry and firm. If any have cracks or thin edges, use those first to prevent them from leaking while baking.
Step 2: Cook the Filling
Preheat your oven to 400°F (200°C). In a skillet over medium heat, crumble the ½ lb sausage and cook it for about 5 minutes, breaking it up with a spoon, until no pink remains. Drain off most of the fat, leaving just a slick, then add the 2 tbsp butter, minced garlic, and reserved chopped mushroom stems. Cook for another 2 minutes, stirring often, until the garlic smells fragrant and the stems soften.
Take the pan off the heat. Fold in the ¼ cup breadcrumbs, ¼ cup Parmesan, ¼ cup mozzarella, and 2 tbsp parsley. Taste the mixture and add salt and pepper. The filling should be moist but not wet, able to clump together when pressed.
Step 3: Stuff the Caps

Arrange the mushroom caps hollow-side up on a rimmed baking sheet. Using a small spoon, mound the filling into each cap, pressing gently so it holds its shape. Don’t pack it down hard or the mushrooms will release liquid and get soggy.
You want a rounded top on each one, with some filling peeking over the edge. If you have a few extra caps, space them evenly so air circulates around every mushroom.
Step 4: Bake Until Golden and Serve

Slide the baking sheet into the hot oven and bake for 15 to 18 minutes, until the cheese on top bubbles and the edges turn deep golden. If your mushrooms are on the larger side, give them a couple more minutes until the caps feel tender when pierced with a fork.
Pull the pan out and transfer the stuffed mushrooms to a serving plate right away. Scatter a little extra parsley over them and serve while they’re still molten and hot.
A Few Notes Before You Stuff
- A small melon baller makes quick work of hollowing out the stems without tearing the cap.
- If the sausage you’re using is lean, stir an extra teaspoon of olive oil into the filling so it doesn’t dry out in the oven.
- Don’t crowd the mushrooms on the sheet. A little space between each cap helps them roast rather than steam.
- For a crispier top, run the pan under the broiler for 1 minute at the very end. Keep a close eye on them.
Bake times by mushroom size:
| Mushroom Cap Size | Bake Time at 400°F |
|---|---|
| Small (1½ inches) | 12 to 14 mins |
| Medium (2 inches) | 15 to 18 mins |
| Large (2½ inches and up) | 19 to 22 mins |
Storing Leftover Stuffed Mushrooms
- Refrigerate: place cooled mushrooms in a single layer inside an airtight container for up to 3 days.
- Reheating: warm them on a baking sheet in a 350°F oven for about 8 to 10 minutes until heated through. The microwave works but softens the cap.
What to Pair With These Mushrooms
Since these are rich and savory, they balance well with something bright. Serve them as a starter before a crisp Caesar salad or a bowl of minestrone for a full Italian dinner. A glass of chilled Pinot Grigio cuts through the cheese and sausage nicely.
Frequently Asked Questions
Can I assemble these a day ahead?
Yes. Stuff the mushrooms, arrange them on the baking sheet, cover, and refrigerate overnight. Bake them straight from the fridge, adding about 3 extra minutes.
How do I stop them from turning watery?
Start with dry caps and cook the filling until all the excess liquid from the stems and sausage evaporates. Baking on a rimmed sheet instead of a dish also lets moisture escape.
Can I use white button mushrooms instead?
You can, but cremini hold their shape better and have a deeper flavor. If you use white mushrooms, pick the biggest ones you can find and reduce the bake time by a couple of minutes.
Do these freeze well?
Freeze unbaked stuffed mushrooms on a tray until solid, then transfer to a freezer bag for up to 1 month. Bake frozen at 400°F for about 22 to 25 minutes, no need to thaw.
