- 1/4 cup (1/2 stick) unsalted butter
- 6 tablespoons all-purpose flour
- 2 celery stalks, cut crosswise into 1/4'-thick slices
- 1 carrot, peeled, thinly sliced
- 1 parsnip, peeled, cut into 1/4'

If using fresh ricotta that has excess liquid, you may need to drain it overnight. Line a fine-mesh strainer with cheesecloth and set it over a medium bowl. Add ricotta; cover with plastic wrap and let drain overnight in refrigerator. If using supermarket ricotta, proceed with recipe; no draining required.
Gently mix ricotta, 1/2 cup plus 2 Tbsp. flour, egg, Parmesan, nutmeg, and salt in a large bowl just to blend (do not overwork). Form dough into a ball (it will be sticky); wrap in plastic and chill for at least 1 hour and up to 1 day.
Line a baking sheet with parchment paper; set aside. Place dough on a lightly floured work surface. Divide dough into 4 equal portions and cover with a clean kitchen towel. Using your hands, roll 1 portion into a 1/2"-diameter rope; cut crosswise into 1/2"-thick pieces. Lightly dust gnocchi with flour and transfer to prepared baking sheet. Repeat with remaining portions of dough. Cover gnocchi with a kitchen towel and chill until ready to cook.
Do Ahead: Gnocchi can be made 2 months ahead. Freeze on sheets, then store, frozen, in an airtight container.
Chicken and Gravy
Bring broth to a boil in a large saucepan. Add chicken; reduce heat to low, cover, and gently simmer until chicken is tender and cooked through, 20–30 minutes. Remove chicken; let cool slightly and shred into bite-size pieces. Bring broth to a boil and cook until reduced to 8 cups, about 15 minutes.
Meanwhile, melt butter in a small heavy saucepan over low heat. Whisk in flour until smooth and cook, whisking constantly, until roux is pale beige in color, about 15 minutes (do not brown).
Scrape roux into simmering broth; whisk until thickened and broth coats the back of a spoon. Reduce heat to low and add vegetables. Cook until tender, about 5 minutes. Add shredded chicken and herbs. Season with salt and pepper. DO AHEAD: Can be made 2 days ahead. Chill, uncovered, until cold; cover and keep chilled. Rewarm before serving.
Cook gnocchi in a large pot of boiling salted water, stirring occasionally, until gnocchi float to the surface, about 2 minutes (slightly longer if frozen). Using a slotted spoon, transfer gnocchi to bowls, dividing equally. Ladle chicken and vegetables with gravy over. Season with pepper and top with Parmesan.
