Garlicky Boursin Stuffed Mushrooms
These Boursin stuffed mushrooms are a quick, crowd-pleasing appetizer. The creamy garlic-herb cheese filling bakes into the earthy mushroom caps, then gets a buttery panko crust that turns crisp and golden.

They take about 35 minutes from start to finish, and they’re just the thing for a dinner party or a cozy night in when you want something that feels a little fancy without much fuss.
Why These Stuffed Mushrooms Work
The Boursin does all the heavy lifting. It’s already packed with garlic, herbs, and a little tang, so you don’t need to chop a thing. The mushrooms turn tender and release their juices as they bake.
The panko topping adds a satisfying crunch that balances the creamy filling. I keep coming back to this recipe because it feels restaurant-worthy but uses only five ingredients.
Ingredients

- 16 oz cremini mushrooms: about 16 medium mushrooms, deep caps work best
- 5.2 oz Boursin Garlic & Fine Herbs cheese: softened slightly so it’s easier to spread
- 2 tbsp unsalted butter: melted
- 1/4 cup panko breadcrumbs: for a light, crispy topping
- 2 tbsp grated Parmesan: adds a salty, nutty finish
- 2 tbsp chopped fresh parsley: save half for the filling, half for the topping
- Salt and freshly ground black pepper: to taste
- Olive oil: for brushing the mushroom caps
Variations / Substitutions
- White button mushrooms: work just as well; pick ones about 2 inches wide for even baking.
- Shallot & Chive Boursin: adds a milder, sweeter onion note.
- No Boursin?: Mix 4 oz softened cream cheese with 1 small grated garlic clove, 1 tsp dried herbs (thyme or parsley), and a pinch of salt.
- Dairy-free: Use a dairy-free cream cheese and season with garlic powder, dried herbs, and a little lemon juice; top with panko tossed in olive oil instead of butter and skip the Parmesan.
Baked Buffalo Chicken Dip makes the perfect dip to serve with these stuffed mushrooms.
How to Make Garlicky Boursin Stuffed Mushrooms
Step 1: Clean and Stem the Mushrooms

Wipe the 16 oz cremini mushrooms clean with a barely damp paper towel. Twist out and discard the stems, then arrange the caps hollow side up on a parchment-lined baking sheet. Brush each cap lightly with olive oil and season the insides with a couple pinches of salt and a few grinds of black pepper.
The mushrooms should look glossy from the oil and ready to cup the filling. A light hand with the oil keeps them from getting soggy.
Step 2: Mix the Filling

Scoop the 5.2 oz Boursin into a small bowl and mash it with a fork until smooth. Stir in half the chopped parsley and a pinch of black pepper. No extra salt is usually needed because the cheese already brings plenty.
The filling will be soft and spreadable, with green flecks of parsley. Its garlic and herb scent is strong right away, a good sign the flavor will carry through baking.
Step 3: Stuff the Caps

Drop a generous teaspoon of the cheese mixture into each mushroom cap. Use the back of the spoon to press it gently into the cavity and mound it slightly on top, leaving a little room for the crumb topping.
The mushrooms should look plump with filling but not overflowing. Any leftover filling can be dolloped onto a few extra caps if you have them.
Step 4: Sprinkle and Bake

Preheat your oven to 400°F (200°C). In a small bowl, combine the 1/4 cup panko, 2 tbsp melted butter, 2 tbsp grated Parmesan, and the remaining parsley. Sprinkle the crumb mixture evenly over each stuffed mushroom, coating the cheese layer. Bake for 18 to 20 minutes, until the caps are tender and the topping is deeply golden.
You’ll hear a faint sizzle from the baking sheet, and the crumb layer will look crisp and toasted. Transfer the mushrooms to a platter and serve while they’re still warm.
Tips for the Best Stuffed Mushrooms
- Choose mushrooms with deep, intact caps so the filling stays put and doesn’t spill out during baking.
- Let the Boursin sit at room temperature for about 10 minutes before mixing; it softens just enough to handle without turning greasy.
- Don’t pack the filling too hard. A light mound bakes more evenly and keeps the texture airy.
- If your mushrooms release a lot of liquid, simply tip the pan gently and drain it off before adding the crumb topping. The filling stays delicious either way.
Bake times depend on the size of your mushrooms.
| Mushroom Size | Bake Time |
|---|---|
| 2-inch (medium) | 18–20 mins |
| 1.5-inch (small) | 15–17 mins |
Storing Leftovers
- Refrigerate: Store leftover mushrooms in an airtight container for up to 2 days. The topping will soften, but the flavor holds well.
- Reheating: Warm them in a 350°F oven for 5 to 8 minutes to crisp up the topping again. The microwave makes them soggy, so skip it if you can.
What Goes Well With Stuffed Mushrooms
These mushrooms are rich, so a crisp, acidic side is welcome. A simple arugula salad with lemon vinaigrette cuts through the creaminess. Set them out with a board of cured meats and olives for an effortless starter spread, or serve a few alongside a roasted chicken for a lighter meal.
Frequently Asked Questions
Why are my mushrooms watery?
That usually comes from washing them. Use a dry paper towel or a barely damp one, and bake at a high temperature like 400°F so the moisture can evaporate quickly. Cremini mushrooms also hold their shape better than white button.
Can I add meat to the filling?
Yes. Fold in 2 tablespoons of cooked, crumbled bacon or finely chopped cooked Italian sausage before you stuff the caps. It adds a savory, smoky layer.
Do I need to pre-cook the mushrooms?
No. They cook through fully in the oven and release their moisture while baking, turning tender without a separate step.
Can I use the mushroom stems?
You can. Chop them finely, sauté in a little butter with a grated garlic clove until the liquid cooks off, then stir that into the cheese mixture. This recipe keeps it simple by discarding them, but it’s a good way to reduce waste.
