FAQ

Q: Do I have to sear the meatballs before putting them in the crock pot
A: Yes, we highly recommend it. Searing the meatballs creates a delicious crust and adds a deep, savory flavor to the soup broth that you would miss by skipping this step.

Q: How do I keep my zucchini noodles from getting mushy
A: To prevent mushy zoodles, it’s crucial to add them to the slow cooker only during the final 15 minutes of the cooking time. This is just enough time to heat them through without overcooking.

Q: Can I use frozen meatballs for this recipe
A: While this recipe is designed for fresh, homemade meatballs, you can use pre-cooked frozen meatballs as a time-saver. Simply add them directly to the slow cooker with the broth and vegetables at the beginning of the cooking time.

Q: What other vegetables can I add to this soup
A: This soup is very versatile! Feel free to add other vegetables like chopped bell peppers, mushrooms, or spinach. Add heartier vegetables like peppers at the beginning and leafy greens like spinach with the zoodles at the end.
