Italian wedding soup is comfort food at its best, filled with tender pasta, juicy meatballs, and a flavorful broth. Making it in the slow cooker means you get all the flavor of a simmered-all-day soup with very little hands-on effort.
Set the oven to 400°F and line a baking sheet with parchment paper.
In a large bowl, combine all the meatball ingredients, mixing just until everything is incorporated.
Shape the mixture into 1.5-inch balls and arrange them on the baking sheet.
Bake for 16–18 minutes, turning once halfway through, until nicely browned. The meatballs don’t need to be fully cooked as they’ll finish cooking in the crockpot.
Place the meatballs in the crockpot. Add the celery, carrots, onion, garlic, chicken broth, Italian seasoning, salt, and pepper.
Cover and cook on low for 6–8 hours or high for 3–4 hours, until the meatballs are fully cooked (at least 145°F inside).
About an hour before serving, stir in the pasta and let it cook until tender.
Add the spinach at the end, letting it wilt into the soup.
Notes
Use your favorite homemade meatball recipe or frozen store-bought ones.
Frozen meatballs can go straight into the crockpot, just allow extra cook time.
Try swapping the beef and pork for Italian sausage, turkey, or chicken.
If you don’t have acini de pepe, orzo or ditalini pasta works well too.
A squeeze of fresh lemon juice at the end adds brightness.
