Step 1: Prepare the Dough
Mix the Ingredients: In a large bowl, combine the flour and salt. Make a well in the center, and add the eggs. Gradually incorporate the flour into the eggs using a fork until a dough forms.
Knead the Dough: Transfer the dough to a floured surface and knead for about 10 minutes until smooth. Wrap it in plastic wrap and let it rest for at least 30 minutes.
Step 2: Make the Filling
Combine Ingredients: In a mixing bowl, combine the ricotta, spinach, Parmigiano-Reggiano, nutmeg, salt, and pepper. Add the egg and mix until well combined.
Taste and Adjust: Taste the filling and adjust the seasoning if needed.
Step 3: Roll Out the Dough
Divide the Dough: After resting, divide the dough into quarters. Keep the unused portions covered to prevent drying.
Roll Thin: Using a pasta machine or rolling pin, roll each quarter into a thin sheet (about 1/16 inch thick).
Step 4: Assemble the Tortellini
Cut the Pasta: Cut the dough into squares (about 2 inches wide).
Fill the Tortellini: Place a small spoonful of filling in the center of each square. Fold the square into a triangle and seal the edges, making sure to press out any air. Then, bring the two corners of the triangle together and pinch to form a tortellini shape.
Repeat: Continue until all the dough and filling are used.
Step 5: Prepare the Broth
Sauté the Vegetables: In a large pot, heat a splash of oil over medium heat. Add the onion, carrot, and celery, and sauté until softened (about 5 minutes).
Add the Broth: Pour in the broth, season with salt and pepper, and add herbs. Bring to a simmer.
Step 6: Cook the Tortellini
Add Tortellini to Broth: Once the broth is simmering, gently drop the tortellini into the pot. Cook for about 4-5 minutes or until they float to the top and are tender.
Serve: Ladle the tortellini and broth into bowls. Garnish with extra Parmigiano-Reggiano and fresh herbs if desired.
