Savory Herb Infused Meatball Soup

Why This Savory Herb Infused Meatball Soup Works

When the beef and turkey are mixed with breadcrumbs, egg, Parmesan, and herbs, the meat holds together instead of crumbling. The breadcrumbs soak up some of the meat juices and egg, so the meatballs stay moist inside instead of drying out. As they brown in the pot, the outside firms up and gets a little crust, which keeps the centers tender while they simmer later.

After the meatballs come out, the onion, garlic, carrots, and celery cook in the same pot. They soften and pick up the browned bits left behind, so the broth doesn’t taste thin. Once the chicken broth and tomatoes go in and start to simmer, the vegetables keep softening and the meatballs finish cooking gently in the hot liquid, staying juicy instead of tough.

Near the end, the spinach and basil only need a short time in the hot soup. The spinach wilts quickly, and the basil warms just enough to spread through the pot without turning dull or mushy.

Mistakes To Avoid

Packing the meat mixture too tightly or overmixing it makes the meatballs dense and tough. The proteins get squeezed together, so instead of staying tender in the broth, the meatballs turn rubbery and heavy in the soup.

Forming meatballs that are much bigger than 1 inch often leads to the outside cooking faster than the center. In the pot, the surface browns and firms up while the middle stays soft and undercooked, so the soup ends up with some meatballs that are not fully done inside.

Crowding the pot while browning the meatballs causes them to steam instead of sear. They release liquid, sit in their own juices, and never get a firm outside, so they break apart more easily later and shed bits of meat into the broth, making it cloudy and gritty.

Letting the soup boil hard after the meatballs go back in can dry them out and break them. A rolling boil makes them knock around and lose their shape, and the broth reduces too fast, leaving a salty, over-concentrated soup.
