A decadent vegetarian entrée for a chilly winter evening, this pie will warm you, body and soul. The rich, savory flavor of this dish can support a heavily herbed gravy, so taste as you add, and don’t be afraid to be a bit heavy-handed!

INGREDIENTS
32 ounces mushrooms, sliced (I used portobello, along with a blend of crimini, shiitake and oyster)
1 large leek, sliced in ¼-inch disks
2 tablespoons olive oil, plus more for brushing on crust
3 tablespoons sherry
2 tablespoons all-purpose flour
1½ cups vegetable broth
½ cup heavy cream
2 teaspoons Dijon mustard
Salt and pepper, to taste
Dried thyme, rosemary and sage, to taste
1 sheet frozen puff pastry (or use our pie crust recipe here)
INSTRUCTIONS
- Preheat the oven to 350°F and set puff pastry aside to thaw.
- In a cast-iron skillet or Dutch oven, season sliced mushrooms and leeks with salt and pepper and sauté them in olive oil. The mushrooms will likely release a substantial amount of water, so continue to cook until the mushrooms have reduced and the filling is browned and beginning to stick.
- Deglaze your pan with sherry, then coat the filling in flour and cook, stirring constantly, until the flour is fully incorporated and the mixture is thick.
- Gradually stir in the vegetable broth and cream, then cook until the filling has thickened. Remove from heat, then add Dijon mustard and dried herbs.
- Place the puff pastry sheet on top of the filling while it’s still in the Dutch oven or cast-iron skillet, cutting slits on top for steam to escape. Brush the top of the crust with olive oil.
- Bake until the crust is golden brown and the filling is bubbling, about 25 or 30 minutes. Let the pie rest for at least 10 minutes before slicing and serving.
