How to Store / Freeze This Mediterranean Stew
Allow the stew to cool completely before storing. This helps prevent condensation, which can lead to a watery texture and spoilage.
Transfer the stew into airtight containers. Choose containers that are appropriately sized for the amount of stew you have. This minimizes air exposure and helps maintain freshness.
For short-term storage, place the containers in the refrigerator. The stew will keep well for up to 4 days. Reheat gently on the stove or in the microwave, adding a splash of vegetable broth if needed to maintain the desired consistency.
For long-term storage, consider freezing the stew. Use freezer-safe containers or heavy-duty freezer bags. If using bags, lay them flat in the freezer to save space and ensure even freezing.
Label each container or bag with the date and contents. This helps you keep track of how long the stew has been stored and ensures you use the oldest batches first.
When ready to enjoy, thaw the stew in the refrigerator overnight. For a quicker option, use the defrost setting on your microwave.
Reheat the stew gently on the stove over medium heat, stirring occasionally. If the stew appears too thick after thawing, add a bit of vegetable broth or water to reach the desired consistency.
Avoid refreezing previously frozen stew. This can affect the texture and flavor, and may also compromise food safety.
For added freshness, consider adding a handful of fresh baby spinach or a squeeze of lemon juice just before serving. This can brighten the flavors and give the stew a freshly made taste.
