Ingredients
Method
- Combine 1 cup chopped onions, bread crumbs, broth–vinegar mixture, olive oil, salt, and pepper. Mix, then gently fold in ground chicken. Shape into 14 meatballs.
- Heat a 12-inch skillet over medium-high with 3 tablespoons olive oil.
- Sear meatballs 2–3 minutes per side until browned. Transfer to a plate.
- Add remaining onions and cook on high, stirring occasionally, until golden and softened, about 6 minutes.
- Add mushrooms and cook 6 minutes until reduced. Sprinkle flour and cook 1 minute.
- Pour in broth–vinegar mixture, scraping up browned bits. Simmer 2 minutes until glossy, then add water and salt.
- Return meatballs, reduce heat, and simmer partially covered for 12 minutes until cooked through and sauce thickens.
Notes
Lightly oil your hands to prevent the chicken mixture from sticking. If the sauce reduces too much, add a splash of water. Cremini mushrooms add deeper flavor. For extra richness, stir in a bit of butter at the end.
