Crockpot Italian Wedding Soup with Mini Meatballs

Imagine a bowl of Italian wedding soup that tastes like it simmered all day on Nonna's stove, but you barely lifted a finger. This Crockpot version delivers golden, savory broth filled with tender mini meatballs, tiny acini di pepe pasta, and bright escarole.

The secret is a slow simmer that lets every ingredient meld into a comforting, soul-warming soup. Best of all, it's a true dump-and-go dinner: brown the meatballs, add everything to the slow cooker, and walk away.

Italian wedding soup is a classic, but it usually requires a watchful eye and a lot of pots. This slow-cooker version simplifies the process without sacrificing flavor. The meatballs are browned first to build a deep fond, then they simmer gently in a rich chicken bone broth with carrots, celery, and onion.

A Parmesan rind infuses the broth with nutty umami as it cooks. The pasta and escarole go in at the end, so they stay perfectly textured. A final swirl of lemon-Parmesan egg ribbon adds a silky, bright finish that makes this soup feel extra special. It's the kind of meal that makes any weeknight feel like a Sunday dinner.

Ingredients

Why this recipe works

The slow cooker is the ideal tool for this soup because it develops flavor over time without constant attention. Browning the meatballs first creates a rich, caramelized crust that deepens the broth's taste.

The low, gentle heat of the slow cooker allows the meatballs to stay tender while the vegetables soften and release their sweetness. The Parmesan rind slowly dissolves, adding a savory, cheesy backbone that you would otherwise need a long simmer to achieve.

Adding the pasta and escarole at the end prevents them from becoming mushy. Acini di pepe, being tiny, cook in just 20 minutes, and escarole wilts quickly. The lemon-Parmesan egg ribbon is a classic Italian technique that enriches the broth and gives it a luxurious, silky texture. The acidity of the lemon brightens the whole soup, balancing the richness of the meatballs and cheese.

Notes and substitutions

For the best flavor, use a high-quality chicken bone broth. The meatballs can be homemade or store-bought; if using store-bought, choose small Italian-style meatballs. If you prefer a leaner soup, you can use ground turkey meatballs, but note that they may be less juicy. The Parmesan rind is a must—it adds a deep, savory flavor that you can't get from grated cheese alone. Save rinds in the freezer and add them to soups and stews.

Acini di pepe is a tiny, bead-like pasta that works perfectly in this soup. If you can't find it, orzo or stelline are good substitutes. Escarole has a mild, slightly bitter flavor that stands up well to the broth; if you can't find it, use baby spinach or Swiss chard.

The lemon-Parmesan egg ribbon is a delicate step, but it's easy if you whisk the egg well and drizzle slowly. If you're not a fan of egg in soup, you can omit it, but it adds a lovely richness.

• chicken bone broth: Use low-sodium chicken broth or vegetable broth for a lighter flavor; reduce salt in the recipe if using regular broth.
• acini di pepe: Substitute with orzo, stelline, or pastina; adjust cook time as needed since smaller pasta may cook faster.
• fresh escarole: Use baby spinach or Swiss chard; if using spinach, add it during the last 5 minutes only.
• Parmesan rind: If no rind is available, add an extra 1/4 cup grated Parmesan to the broth, and skip the rind.
