Ingredients
- Fresh mushrooms, such as white button or cremini mushrooms
- Boursin Garlic & Fine Herbs cheese
- Olive oil or melted butter
- Salt and freshly ground black pepper
- Fresh parsley or chives, for garnish
Optional additions include:
- Breadcrumbs for a lightly crisp topping
- Grated Parmesan cheese
- Minced garlic
- Cooked and crumbled bacon
- Finely chopped spinach or green onions
- A splash of lemon juice
How to Make It
Prepare the oven. Heat the oven to 375°F (190°C). Lightly grease a baking dish or line a baking sheet with parchment paper.
Clean the mushrooms. Wipe the mushrooms with a damp paper towel to remove any dirt. Avoid soaking them, as mushrooms absorb water easily and may become soggy.
Remove the stems. Gently twist or pull out the stems, creating a hollow center for the filling. Reserve the stems for another recipe, or finely chop them and mix them into the filling.
Season the mushroom caps. Arrange the caps in the prepared dish with the hollow sides facing up. Brush them lightly with olive oil or melted butter, then season with a small amount of salt and pepper.
Fill the mushrooms. Spoon Boursin cheese into each mushroom cap, filling it generously without allowing the cheese to spill over the sides. Add breadcrumbs or Parmesan on top if desired.
Bake until tender. Bake the mushrooms until the caps are tender and the cheese is warm and lightly golden, usually about 18 to 25 minutes depending on their size.
Garnish and serve. Let the mushrooms rest for a few minutes, then finish with chopped parsley, chives, or a light squeeze of lemon juice.
How to Serve It
Serve Boursin stuffed mushrooms warm as an appetizer with toothpicks or small forks. They pair beautifully with a cheese board, crackers, olives, and roasted vegetables.
For a dinner-party menu, serve them before roast chicken, steak, pasta, or a fresh green salad. A sprinkle of parsley, chives, or Parmesan adds a bright and attractive finishing touch.
How to Store It
Place cooled leftovers in an airtight container and refrigerate for up to 3 days. To reheat, arrange the mushrooms in a baking dish and warm them in a 350°F (175°C) oven until heated through. This helps preserve their texture better than microwaving.
Freezing is possible, but the mushrooms may become softer after thawing. If freezing, place the cooled mushrooms in a freezer-safe container and use them within 1 month. Reheat them from frozen in the oven until hot, adding a few extra minutes as needed.
Helpful Tips
- Choose similar-sized mushrooms so they cook evenly and are easy to serve.
- Do not overfill the caps. Boursin melts as it heats, so leave a little space around the top.
- Avoid excess moisture. Clean the mushrooms gently and bake them in a single layer to prevent steaming.
- Use softened cheese. Let the Boursin sit at room temperature for a short time so it spreads easily.
- Add the garnish after baking. Fresh herbs retain more color and flavor when sprinkled on just before serving.
Optional Variations
- Crispy Parmesan topping: Mix breadcrumbs with grated Parmesan and a little olive oil, then sprinkle over the mushrooms before baking.
- Bacon and Boursin mushrooms: Fold finely chopped cooked bacon into the cheese filling for a smoky, savory variation.
- Spinach and herb mushrooms: Add finely chopped, well-drained spinach and a little lemon zest to the Boursin.
- Spicy stuffed mushrooms: Stir red pepper flakes or a dash of hot sauce into the filling.
- Extra-garlicky version: Add a small amount of minced garlic for a stronger garlic flavor.
Frequently Asked Questions
Can I prepare Boursin stuffed mushrooms ahead of time?
Yes. Assemble the mushrooms several hours ahead, cover them, and refrigerate until ready to bake. Add a few extra minutes to the baking time if they go into the oven cold.
Should I wash mushrooms before stuffing them?
It is best to wipe them with a damp paper towel or use a soft brush. If you rinse them, do so quickly and dry them thoroughly before filling.
Can I use a different flavor of Boursin?
Absolutely. Garlic and Fine Herbs is a classic choice, but pepper, shallot and chive, or other available varieties can work well.
Why are my stuffed mushrooms watery?
Mushrooms naturally release moisture as they cook. Excess water is more likely if they are soaked during cleaning, crowded in the baking dish, or cooked at too low a temperature.
Can I make these without breadcrumbs?
Yes. Breadcrumbs are optional and mainly add a crisp topping. The mushrooms remain creamy and flavorful with Boursin alone.
