When preparing eggplant for this casserole, consider salting the slices before cooking. This technique helps draw out excess moisture and reduces any potential bitterness. Simply sprinkle a light layer of salt over the eggplant slices and let them sit for about 15-30 minutes. Afterward, rinse the slices under cold water and pat them dry with a paper towel. This step ensures that your casserole won't become watery and enhances the overall flavor of the dish.

How to Store or Freeze This Casserole
Allow the eggplant parmesan casserole to cool completely at room temperature before storing. This prevents condensation, which can make the dish soggy.
For short-term storage, cover the casserole dish tightly with plastic wrap or transfer individual portions into airtight containers. Store in the refrigerator for up to 3-4 days.
To freeze, first line the casserole dish with aluminum foil, leaving enough overhang to cover the top. Assemble the casserole as instructed, but do not bake it.
Once assembled, wrap the casserole tightly with the overhanging foil, ensuring it is completely sealed. For added protection, place the foil-wrapped casserole into a large freezer bag or wrap it again with another layer of foil.
Label the package with the date and contents using a permanent marker. This helps you keep track of how long it has been stored.
Store the wrapped casserole flat in the freezer. It can be frozen for up to 2-3 months without losing its delightful flavors.
When ready to enjoy, thaw the casserole in the refrigerator overnight. This slow thawing process helps maintain the texture of the eggplant and cheese.
Once thawed, bake the casserole in a preheated oven at 375°F (190°C) for about 50-60 minutes, or until the cheese is bubbly and golden brown. If baking from frozen, add an additional 20-30 minutes to the baking time.
For individual portions, reheat in the microwave or oven until heated through, ensuring the cheese is melted and the casserole is warmed evenly.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover eggplant parmesan casserole in an oven-safe dish. Cover it with aluminum foil to prevent the cheese from burning. Heat for about 20-25 minutes, or until the casserole is warmed through and the cheese is melty and bubbly.
For a quicker option, use the microwave. Transfer a portion of the casserole to a microwave-safe plate. Cover it with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating. Let it sit for a minute before enjoying.
If you have an air fryer, preheat it to 350°F (175°C). Place the eggplant parmesan casserole in the air fryer basket, ensuring it's in a single layer. Heat for about 5-7 minutes, checking frequently to avoid overcooking. This method will give the cheese a delightful crispiness.
On the stovetop, use a skillet over medium heat. Add a splash of olive oil or a bit of water to the pan to prevent sticking. Place the casserole in the skillet, cover with a lid, and heat for about 8-10 minutes, stirring occasionally to ensure even warming.
