Common Mistakes to Avoid
When making Slow Cooker White Lasagna Soup, it’s easy to overlook some details. Here are some common mistakes and how to avoid them.
- Skipping the seasoning: Not seasoning your ingredients can lead to bland soup. Always ensure you add the right amount of salt and spices for flavor.
- Overcooking the chicken: Cooking the chicken for too long can make it dry. Monitor the cooking time closely, especially if using the high setting.
- Not shredding the chicken properly: If the chicken isn’t shredded well, it can result in large chunks in your soup. Use two forks to shred thoroughly before returning it to the pot.
- Ignoring the noodles: Adding uncooked noodles directly to the slow cooker may result in mushy pasta. Always cook and drain them separately before adding.
- Neglecting fresh ingredients: Fresh spinach adds a burst of nutrition and flavor. Avoid skipping this ingredient or using wilted greens.
Refrigerator Storage
- Store in an airtight container for up to 3-4 days.
- Allow the soup to cool fully before refrigerating.
