How to Store or Freeze This Casserole
Allow the French toast casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, cover the baking dish tightly with plastic wrap or aluminum foil and place it in the refrigerator. It will stay fresh for up to 3-4 days.
If you prefer individual servings, cut the casserole into portions and store them in airtight containers. This makes it easy to grab a quick breakfast or snack.
To freeze, wrap the entire casserole or individual portions tightly in plastic wrap, followed by a layer of aluminum foil. This double wrapping helps prevent freezer burn.
Label the wrapped casserole with the date and contents. It can be stored in the freezer for up to 2-3 months.
When you're ready to enjoy the frozen casserole, thaw it in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor.
To reheat, preheat your oven to 350°F (175°C). Remove any plastic wrap and cover the casserole with aluminum foil. Bake for about 20-25 minutes, or until heated through.
For a quicker option, individual portions can be reheated in the microwave. Place a portion on a microwave-safe plate and heat on high for 1-2 minutes, or until warmed through.
If you prefer a crispier top, you can uncover the casserole for the last 5-10 minutes of reheating in the oven. This will help restore that delightful golden-brown crust.
Always check the internal temperature of the reheated casserole to ensure it reaches at least 165°F (74°C) for safe consumption.
