- 1 tablespoon butter
- 1 pound sliced fresh mushrooms
- 5 scallions, sliced
- 1 cup cooked brown rice
- 1/2 cup sour cream
- 4 teaspoons dried dill weed
- 1 teaspoon salt
- 1/4 teaspoon ground black pepper
- 1 (17.5 ounce) package frozen puff pastry, thawed
- Preheat oven to 400 degrees F (200 degrees C).
- Melt butter in a large skillet over medium heat. Add mushrooms and scallions; cook, stirring occasionally, until softened, about 10 minutes. Transfer to a bowl.
- Stir brown rice, sour cream, dill, salt, and pepper into the mushroom mixture in the bowl.
- Unfold 1 puff pastry sheet onto an ungreased baking sheet. Spread mushroom mixture evenly on top, leaving a 1-inch border on all sides. Lay the second puff pastry sheet on top. Seal edges by pressing together with a fork.
- Bake in the preheated oven until pastry is puffed up and golden brown on top, about 30 minutes. Cool slightly before serving, about 10 minutes.
