Zucchini brings a dose of vitamin C and antioxidants, while potatoes offer potassium and vitamin B6.

How to store leftover moussaka?

Preserving the delightful flavors of your vegetarian lentil moussaka is easily done with the correct storage techniques. Before storing, first allow any leftovers to come to room temperature. For short-term storage, refrigerating your leftovers is the best option. Place the moussaka in an airtight container to shield it from external odors and preserve its deliciousness. This method keeps your dish fresh for up to 3–4 days. When ready for another serving, a quick reheat in the oven or microwave will rejuvenate all those wonderful flavors.

For more extended storage, consider freezing individual portions. Wrap them carefully in aluminum foil, or use freezer-safe containers. The moussaka should keep well in the freezer for up to 3 months. Be sure to thaw the frozen portions in the refrigerator overnight before reheating them in the oven or microwave for a comforting and convenient meal. If you've made a big batch of this wholesome dish and have plenty of leftovers, opt for these easy storage techniques and there's no need for it to go to waste!
