Heat 1 teaspoon olive oil in a skillet over medium heat. Add cubed chicken and sauté until no longer pink. Season with a pinch of salt and ground white pepper. Continue cooking until chicken is cooked through. Transfer to a bowl and set aside.
02 -
In the same skillet, add 2 teaspoons olive oil and the unsalted butter. Sauté minced garlic and chopped onion over medium heat until fragrant and translucent. Add sliced mushrooms and cook on medium-high heat until golden brown and moisture evaporates.
03 -
Return the cooked chicken to the skillet with the mushroom mixture. Sprinkle in all-purpose flour, black pepper, Italian herbs, dried tarragon, and salt. Stir to coat everything evenly.

Pour in heavy cream while stirring constantly to avoid lumps. Allow the mixture to thicken over medium heat, then remove from heat and let cool.

Working with chilled puff pastry, cut 2-inch rounds for the bases and arrange them on a parchment-lined baking sheet, spaced apart. Cut an equal number of 2-inch rounds, and using a 1.25-inch cutter, remove centers to create rings. For every base, prepare two rings.
06 -
Brush base rounds with egg wash (egg whisked with milk). Place one pastry ring onto each base, lightly pressing to secure the edges. Prick the center of the base 2-3 times with a fork to minimize puffing. Brush the ring’s outer edge with egg wash, add the second ring, and give a final egg wash layer to the entire shell. Repeat for all shells.

Refrigerate the assembled shells for 15 minutes.
08 -
Bake shells in a preheated oven at 400°F for 15–20 minutes until golden and puffed. Allow pastries to cool on the baking sheet for 10–15 minutes.

Carefully spoon the cooled chicken and mushroom filling into the hollow centers of the pastry shells. Garnish with finely chopped chives and serve immediately.
