Boursin Stuffed Mushrooms (Air Fryer)
Boursin Stuffed Mushrooms are an easy, creamy, and flavorful appetizer made with tender mushrooms filled with herbed Boursin cheese and finished with a golden, savory topping. Cooking them in the air fryer makes them beautifully tender with lightly crisp edges while keeping the cheesy filling warm and creamy. They’re perfect for parties, holiday gatherings, game nights, or a quick side dish.
Ingredients
- 16 oz (450 g) white button or cremini mushrooms
- 5.2 oz (150 g) Boursin Garlic & Fine Herbs cheese
- ¼ cup finely grated Parmesan cheese
- 2 tablespoons breadcrumbs
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1 tablespoon fresh parsley, finely chopped
- ¼ teaspoon black pepper
- ¼ teaspoon Italian seasoning
- Pinch of salt, optional
- 1 teaspoon fresh lemon juice, optional
Directions
1. Prepare the Mushrooms
Gently wipe the mushrooms clean with a damp paper towel. Avoid soaking them in water because mushrooms can absorb moisture and become watery.
Carefully remove the stems from each mushroom.
Use a small spoon to gently scrape out a little of the inside if you need more room for the filling.
Set the mushroom caps aside.
2. Prepare the Filling
Finely chop the mushroom stems.
Heat a small skillet over medium heat and add the olive oil.
Add the chopped mushroom stems and minced garlic. Cook for approximately 3–4 minutes, stirring occasionally, until the mushrooms soften and most of their moisture has evaporated.
Remove from the heat and allow the mixture to cool slightly.
In a bowl, combine:
- Boursin cheese
- Cooked mushroom stems
- Parmesan cheese
- Breadcrumbs
- Fresh parsley
- Black pepper
- Italian seasoning
Add lemon juice if using.
Mix until everything is evenly combined and creamy.
3. Fill the Mushrooms
Spoon the Boursin mixture into each mushroom cap.
Fill them generously, but avoid piling the filling too high because it can overflow during cooking.
For an extra golden finish, sprinkle a small amount of Parmesan or breadcrumbs over each stuffed mushroom.
4. Preheat the Air Fryer
Preheat your air fryer to 375°F (190°C) for approximately 3 minutes.
Lightly grease the air fryer basket with cooking spray or a small amount of olive oil.
5. Air Fry
Arrange the stuffed mushrooms in the air fryer basket in a single layer.
Leave a little space between them so the hot air can circulate properly.
Air fry at 375°F (190°C) for 8–10 minutes, or until:
- The mushrooms are tender.
- The cheese filling is hot and creamy.
- The tops are lightly golden.
For larger mushrooms, you may need an additional 2–3 minutes.
6. Serve
Carefully remove the mushrooms from the air fryer and let them rest for 2–3 minutes.
Garnish with fresh parsley and serve warm.
Tips for Perfect Stuffed Mushrooms
Choose similarly sized mushrooms: This helps them cook evenly.
Don’t wash the mushrooms excessively: A damp paper towel is usually enough to clean them.
Cook the mushroom stems first: Removing their excess moisture prevents the filling from becoming watery.
Don’t overcrowd the basket: Cook in batches if necessary.
Use softened Boursin: Let the cheese sit at room temperature for about 10–15 minutes before mixing. This makes it easier to combine with the other ingredients.
Watch the final minutes: Boursin melts quickly, so keep an eye on the mushrooms toward the end of cooking.
Variations
Bacon Boursin Mushrooms
Add ¼ cup cooked and crumbled bacon to the filling for a smoky, savory version.
Spinach Boursin Mushrooms
Mix ¼ cup finely chopped cooked spinach into the cheese filling.
Make sure to squeeze out excess moisture from the spinach first.
Spicy Stuffed Mushrooms
Add ¼ teaspoon crushed red pepper flakes or a finely chopped jalapeño to the filling.
Extra Cheesy Mushrooms
Mix shredded mozzarella into the filling and sprinkle additional Parmesan over the tops before air frying.
Chicken Stuffed Mushrooms
Add a few tablespoons of finely chopped cooked chicken for a heartier appetizer.
What to Serve With Them
These stuffed mushrooms are delicious alongside:
- Grilled steak
- Roast chicken
- Grilled fish
- Pasta
- Garlic bread
- Fresh green salad
- Roasted vegetables
They also make an excellent appetizer served with toothpicks for easy entertaining.
Make-Ahead Instructions
The mushrooms can be cleaned and stuffed several hours before cooking.
Arrange them in a covered container and refrigerate until you’re ready to air fry.
For the best results, take them out of the refrigerator about 10–15 minutes before cooking.
You may need to add an extra minute or two to the air-frying time if they’re very cold.
Storage and Reheating
Store leftover stuffed mushrooms in an airtight container in the refrigerator for up to 3 days.
To reheat, place them in the air fryer at 350°F (175°C) for approximately 3–5 minutes, until heated through.
Avoid microwaving if possible, as it can make the mushrooms soft and watery.
Frequently Asked Questions
Can I use cremini mushrooms?
Yes. Cremini mushrooms are an excellent choice and provide a slightly deeper flavor than white button mushrooms.
Can I use another Boursin flavor?
Absolutely. Garlic & Fine Herbs is a classic choice, but other savory Boursin varieties can work depending on your preference.
Do I need to pre-cook the mushrooms?
No. The mushroom caps cook directly in the air fryer. However, cooking the chopped stems before adding them to the filling helps remove excess moisture.
Why are my stuffed mushrooms watery?
Mushrooms naturally release water as they cook. Avoid soaking them before cooking, cook the chopped stems until their moisture evaporates, and don’t overcrowd the air fryer basket.
