Instructions
Make the Matzo Ball Mixture
In a large bowl, combine the ground chicken, matzo meal, shredded onion, egg, parsley, salt, thyme, and black pepper. Mix gently until just combined.
Cover and refrigerate for at least 15 minutes (or up to 4 hours). This helps the matzo balls hold together.
Start the Soup
Heat the vegetable oil in a large pot over medium heat. Add the onion, celery, celery leaves, and carrot. Cover and cook, stirring occasionally, until the vegetables begin to soften, about 5 minutes.
Add the chicken broth, thyme, and bay leaf. Bring to a boil, then reduce the heat to medium-low. Cover with the lid slightly ajar and simmer for 15 minutes.
Shape and Cook the Matzo Balls
With wet hands, shape the chicken mixture into 24 equal balls and place them on a plate.
One at a time, gently drop the balls into the simmering soup. Keep the lid slightly ajar and simmer until the matzo balls are cooked through, about 20 minutes.
Season the soup with salt and pepper to taste.
Serve
Discard the bay leaf. Ladle the soup into bowls, sprinkle with fresh parsley, and serve hot.
Notes
Tips & Notes
Wet hands are key when shaping the matzo balls — the mixture is sticky.
If you prefer lighter matzo balls, handle the mixture gently and don’t overmix.
Leftovers keep well in the fridge for up to 3 days; the flavors deepen overnight.
If the soup thickens after refrigeration, just add a splash of broth when reheating.
