Why you’ll Love this Recipe
I absolutely love serving this ragout of mushrooms in pastry shells. The filling is rich, creamy, and packed with flavor, making it a dish everyone at the table will enjoy.
Mushroom Ragout
One of the best things about this recipe is that you can prepare most of it in advance. If you make the pastry shells yourself, you can prepare them a few days ahead. The ragout of mushrooms can also be made 1–2 days in advance, making this a wonderfully convenient dish for entertaining.

Easy Ragout of Mushrooms with Truffle
For this creamy ragout, you can use regular white mushrooms, but I recommend chestnut or cremini mushrooms if you can find them. I personally find them a little more flavorful. To add more flavor, I add onion, garlic and thyme. A match made in heaven!
And don’t worry if you end up with leftovers. The ragout is just as delicious the next day, served with some rice for an easy and comforting meal.
How to Make Homemade Pastry Shells
These pastry shells give the creamy ragout of mushroom an elegant touch. You can easily find ready-made pastry shells in many stores, but making them yourself is also surprisingly simple and delicious.
All you need is fresh puff pastry. Cut out stars using a cookie cutter. The bottom layer should be a whole star, while the layers on top should have a smaller star cut out from the center. Make sure you build the shells high enough to hold plenty of filling, about three layers on top works well.
For an extra finishing touch, sprinkle the pastry with sesame seeds before baking.
Don’t throw away the little stars you cut from the center. Brush them with a little egg yolk, sprinkle with sesame seeds, and bake them alongside the pastry shells. They make a cute little edible garnish to serve with the ragout of mushroom.

Truffle Ragout with Mushrooms
Although this recipe is very easy to make, the finished pastry shells look wonderfully elegant and taste just as good. For the filling, I use Boursin with truffle flavor, which adds a deliciously rich and indulgent flavor to the mushroom ragout.
