These Boursin stuffed mushrooms are like little flavor bombs! The creamy cheese filling mixed with herbs makes for a tasty treat that’s easy to pop in your mouth.
They’re perfect as a party snack or a cozy night treat. I love how simple they are to make, just stuff, bake, and enjoy while they are warm—deliciously cheesy goodness!
Key Ingredients & Substitutions
Mushrooms: Large cremini or white button mushrooms are perfect for stuffing. You can also use portobello mushrooms for a heartier option. Just keep in mind they may take a bit longer to cook.
Boursin Cheese: This creamy cheese adds wonderful flavor. If you can’t find it, you could substitute with any herbed cream cheese. Adding some herbs like chives and basil can mimic that Boursin flavor.
Parmesan Cheese: Grated Parmesan brings a nice salty touch. If you’re looking for a dairy-free version, nutritional yeast can offer a cheesy flavor without the dairy. Or, use a vegan Parmesan substitute if desired.
Breadcrumbs: They add a nice crunch on top. If you’re gluten-free, try using gluten-free breadcrumbs or even crushed nuts for some texture.
How Do You Get the Right Texture for Your Stuffed Mushrooms?
The texture of the stuffed mushrooms is key to enjoying this dish. Sautéing the chopped stems and onion gives a nice soft filling that contrasts nicely with the tender mushroom caps.
- Make sure to cook the mixture until it’s softened—about 5 minutes should do it.
- When stuffing the mushrooms, don’t pack too tightly; this ensures they cook evenly and stay moist.
- If using breadcrumbs, a light sprinkle over the top creates a crispy topping, elevating the texture.

- 1 container (5.2 oz) Boursin cheese (Garlic & Herbs flavor)
- 1/4 cup grated Parmesan cheese
- 1/4 cup finely chopped onion or shallot

How Much Time Will You Need?
This tasty dish will take about 10 minutes for prep and about 20 minutes to bake, so you’re looking at a total of around 30 minutes from start to finish. Perfect for a quick appetizer!
Step-by-Step Instructions:
1. Prepare the Oven and Baking Sheet:
Start by preheating your oven to 375°F (190°C). Grab a baking sheet and lightly grease it or line it with parchment paper to make cleanup easier later.
2. Clean the Mushrooms:
Take your mushrooms and give them a nice clean. Wipe them gently with a damp paper towel to remove any dirt. Carefully pop out the stems, and make sure to finely chop those stems because we’ll be using them in the filling!
3. Sauté the Filling Ingredients:
In a skillet, add 1 tablespoon of olive oil and heat it over medium heat. Toss in the chopped mushroom stems, onion (or shallot), and minced garlic. Sauté everything for about 5 minutes until it’s softened and smells amazing. Once done, take it off the heat and let it cool for a moment.
4. Make the Filling:
In a mixing bowl, combine the sautéed mixture with the Boursin cheese and grated Parmesan cheese. Don’t forget to season it with a pinch of salt and a sprinkle of black pepper. Mix everything well until it’s nice and creamy.
5. Stuff the Mushrooms:
Take your cleaned mushroom caps and fill them generously with the creamy Boursin filling. Make sure each one is well stuffed, but not overflowing too much!
6. Season and Prepare for Baking:
Drizzle the remaining tablespoon of olive oil over the stuffed mushrooms. If you want a crispy topping, sprinkle some breadcrumbs on top of the stuffed mushrooms.
7. Bake to Perfection:
Pop the baking sheet in the preheated oven and let those bad boys bake for about 18-20 minutes. They should be tender, and the tops will be golden and bubbling.
8. Cool and Garnish:
Once baked, take them out of the oven and let them cool for a few minutes. Before serving, sprinkle some freshly chopped parsley on top for a pop of color.
9. Time to Enjoy:
Serve these delicious Boursin stuffed mushrooms warm, either as an appetizer or as a fabulous side dish. Enjoy the cheesy, savory goodness!
Can I Use Different Types of Mushrooms?
Absolutely! While cremini and white button mushrooms work best for stuffing, you can also use portobello mushrooms for a heartier bite. Just remember that larger caps may require a longer baking time.
How Can I Make This Recipe Gluten-Free?
If you want to make these mushrooms gluten-free, simply substitute regular breadcrumbs with gluten-free breadcrumbs or crushed nuts. Both options will add a nice crunch without the gluten!
Can I Prepare These Ahead of Time?
Yes, you can prepare the stuffed mushrooms in advance! Stuff the mushrooms up to a day ahead and store them covered in the refrigerator. When you’re ready to bake them, just pop them in the oven, adding a couple of extra minutes to the baking time if they’re cold from the fridge.
What Should I Serve With Boursin Stuffed Mushrooms?
These tasty bites pair wonderfully with a side salad, crusty bread, or even a glass of wine! They can serve as a great appetizer before a larger meal or as part of a tapas-style spread.
