01 - On a clean work surface, mound the flour and create a deep well in the center. Crack the eggs into the well and add the salt. Using a fork, gently whisk the eggs and gradually incorporate the flour from the inner edges of the well until a shaggy dough forms. Knead the dough by hand for 7–8 minutes until it becomes smooth and elastic. Wrap tightly in plastic wrap and let it rest at room temperature for 20 minutes.
02 - While the dough rests, combine the finely chopped cooked chicken, ricotta cheese, grated Parmesan, minced garlic, chopped parsley, and ground nutmeg in a medium mixing bowl. Season generously with salt and pepper. Mix thoroughly until all ingredients are evenly distributed.
03 - Cut the rested dough into 4 equal sections. Keeping the remaining dough covered, roll one section out thinly to about 1/16-inch thickness. Cut the sheet into 2-inch squares or circles. Place a small dollop of the chicken filling in the center of each piece. Fold the dough over to form a triangle or half-moon, pressing firmly to seal the edges and remove air pockets. Wrap the filled pasta around your finger and press the corners together to form the traditional tortellini shape. Repeat with remaining dough and filling.
04 - Bring a large pot of salted water to a rolling boil. Carefully drop the formed tortellini into the water in batches to avoid overcrowding. Cook for 3–4 minutes, or until they float to the surface. Remove gently using a slotted spoon and transfer to a warm plate.
05 - While the pasta cooks, melt the unsalted butter in a saucepan over medium heat. Pour in the heavy cream and bring to a gentle simmer. Let cook for 2–3 minutes until slightly thickened. Stir in the Parmesan cheese until completely melted and the sauce is smooth. Remove from heat and season with freshly ground black pepper to taste.
06 - Gently toss the cooked tortellini in the warm cream sauce to coat evenly. Plate the pasta and garnish generously with additional chopped fresh parsley and extra Parmesan cheese.
