Tiny diamond-cut egg pasta in golden broth is a classic Italian holiday first course. This light protein-rich mediterranean soup is ideal for intermittent fasting and family celebrations.
Bring the chicken broth to a gentle simmer in a large pot over medium-low heat.
Add the whole celery stalk and carrot; simmer uncovered for 30 minutes to allow the flavor to infuse, skimming any foam occasionally.
While the broth simmers, cut the egg pasta sheets into small diamond-shaped pieces (about 1/2-inch squares).
Remove the celery and carrot from the broth. Season the broth with salt and black pepper.
Increase the heat to medium-high so the broth is just bubbling; add the pasta diamonds and gently cook for 4–5 minutes until just tender.
Whisk the eggs in a bowl, and slowly stream them into the hot soup, stirring gently to create light ribbons.
Ladle the soup into bowls and top each with grated Parmesan cheese. Serve immediately while hot.
