Prep the Base: Dice the onion and carrots. Mince the garlic. Add them to the crock pot with the Italian seasoning, salt, pepper, and chicken broth.
1 cup diced white onion, 1 cup diced carrots, 2 cloves garlic, 1 teaspoon Italian seasoning, 1 teaspoon salt, ½ teaspoon black pepper, 8 cups chicken broth
Add the Meatballs: Stir in the frozen mini meatballs. No need to thaw—just drop them in and make sure they’re covered with broth.
12 ounces frozen mini meatballs
Simmer Low and Slow: Cover and cook on low for 6–7 hours or high for 3–4 hours. This gives the flavors time to "marry" like the soup's name promises.
Add the Pasta: About 20 minutes before you're ready to eat, stir in the dry pasta. If using slightly larger pasta like orzo, check after 25–30 minutes for tenderness.
¾ cup dry acini de pepe pasta
Finish with Spinach: Just before serving, stir in the chopped baby spinach. It’ll wilt in under a minute and make everything look extra gourmet.
4 cups chopped baby spinach
Top and Serve: Serve hot with a sprinkle of shredded Parmesan cheese. Optional but highly encouraged: crusty bread on the side.
