How to Make Olive Garden Stuffed Mushrooms
- Step 1 – Prepare oven and baking dish. – Preheat the oven to 350 degrees. – Spray a baking dish large enough to hold the mushrooms with a non-stick cooking spray.
Step 2 – Clean and remove stems from mushrooms. Remove the stems off the mushrooms from top of the mushrooms. Clean with a dry paper towel (due not use water or it will make the mushrooms soggy).
Step 3 – Mix clam stuffing ingredients together – Stir together all the filling ingredients in a mixing bowl.
Step 4 – Divide the stuffing mixture in the mushroom cap – Add 1-2 spoons of the mixture inside mushroom cavity and slightly mound. Place filling side up on the baking dish. You should be able to stuff 8-12 mushrooms based on the size of your mushrooms.
Step 5 – Top with Melted Butter – Then drizzle ¼ cup of melted butter and oregano over the prepared mushrooms. Cover the small baking dish with foil and bake for 20-30 minutes until the mushrooms are tender.
- Step 6 – Mozzarella Cheese on Top – Remove the foil and sprinkle the top of each mushroom with the grated mozzarella cheese. Bake (uncovered) for 2-3 minutes until the cheese is melted.
- Step 7 – Serve and Enjoy – Then the mushrooms are ready to serve and enjoy. Depending on how many are in a container but usually you can get about 12 mushrooms depending of the size.
Recipe Tips
- Make in advance – You can easily make these ahead of time. We recommend making the same day your want to serve them. Just prepare as recipe indicates and place in the refrigerator.
- Dry Mushrooms – Make sure mushrooms are dry before stuffing with the mixture. Pat dry any moisture that is on the mushrooms.
- Cheeses – You can use different types of cheese. Parmesan, Romano Cheese, Italian Cheese and Mozzarella cheeses are good suggestions.
- Shredded Cheese – We recommend freshly grated mozzarella cheese instead of the prepacked shredded cheese.
How to Store
These are best served fresh but you can refrigerate the leftovers for up to 3 days. Reheat in the oven or air fryer to make them heated through and slightly crispy again.
Frequently Asked Questions
When making stuffed mushrooms we usually choose a large white button mushroom or cremini mushrooms. These two are perfect for stuffing. You can also use a portobello mushroom if you want something larger.
Purchase mushrooms that are firm and plump as these are usually the ones that are the freshest. Depending on the size, I usually purchase the mushrooms that are in bulk. Make sure to clean the mushrooms completely before stuffing. After washing completely with a brush or your hands, allow them to dry completely before stuffing.
No, there is no need to bake the mushrooms before adding the stuffing. Just prepare the mushrooms and remove the stems, wash and dry the mushrooms to prepare the stuffing.

I’m assuming that in the directions the first ingredient for the filling was meant to say “Minced CLAMS” right???
Bella – Yes, that is correct. There was a typo in the recipe and I have fixed it. Thank you so much for letting me know!
Can I make the stuffing ahead of time, store in refrigerator & put together & cook the day I need them? Say about 3 days from making the stuffing?
