How to Store or Freeze This Recipe
Allow the taco soup to cool completely before storing. This helps maintain the integrity of the vegetables and prevents condensation from forming inside the storage container.
Transfer the cooled soup into airtight containers. For easy portion control, consider using individual serving-sized containers. This makes reheating a breeze and ensures you only thaw what you need.
Label each container with the date. This is crucial for keeping track of freshness, especially if you plan to store the soup for an extended period.
Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The flavors will meld together beautifully, making it even more delicious.
For longer storage, place the containers in the freezer. The taco soup can be frozen for up to 3 months without losing its delightful taste and texture.
When ready to enjoy, thaw the soup in the refrigerator overnight. This slow thawing process helps maintain the quality of the ingredients.
Reheat the soup on the stovetop over medium heat, stirring occasionally until heated through. Alternatively, you can use the microwave, heating in 1-minute intervals and stirring in between to ensure even heating.
If the soup appears too thick after reheating, add a splash of vegetable broth or water to reach your desired consistency. Adjust the seasoning if necessary, as freezing can sometimes dull the flavors.
Enjoy your reheated slow cooker taco soup with your favorite toppings, such as avocado, fresh cilantro, or a squeeze of lime juice.
How to Reheat Leftovers
- For stovetop reheating, pour the taco soup into a saucepan and heat over medium heat. Stir occasionally until it's warmed through, usually about 5-7 minutes.
- To reheat in the microwave, transfer a portion of the soup to a microwave-safe bowl. Cover with a microwave-safe lid or plate to prevent splatters. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating.
- If you prefer using the slow cooker again, pour the leftover taco soup back into the slow cooker. Set it to low and heat for about 1-2 hours, or until it's hot.
- For a quick reheat, use an instant pot on the sauté setting. Add the soup and stir frequently, heating for about 5 minutes or until it reaches your desired temperature.
- To reheat in the oven, preheat your oven to 350°F (175°C). Transfer the soup to an oven-safe dish, cover with foil, and heat for about 20-25 minutes, or until hot.
