Additional Tips

- Keep Meatballs Juicy – Adding a bit of milk or broth to the chicken mixture helps keep them tender and moist.

- Deglaze for Intensity – Use beef broth to scrape up the caramelized bits from the pan for a more robust sauce.
- Don’t Overmix – Gently combine the meat mixture to avoid tough, dense meatballs.
- Simmer for Richness – Let the meatballs bathe in the oniony sauce for at least 10 minutes to absorb all the flavors.
- Make It Ahead – Caramelized onions taste even better the next day, so prep them in advance for a quicker meal.

- Garnish for the Win – A sprinkle of fresh thyme or parsley adds color and a burst of freshness.
