How to Store / Freeze This Casserole
Allow the baked apple French toast casserole to cool completely at room temperature before storing. This helps prevent condensation, which can make the casserole 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 days.
If you prefer individual servings, cut the casserole into portions and store them in airtight containers. This makes it easier to reheat just the amount you need.
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 and keeps the casserole fresh.
Label the wrapped casserole with the date and contents to keep track of its freshness. It can be frozen for up to 2 months.
When you're ready to enjoy the frozen casserole, thaw it in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor of the baked apple French toast casserole.
Reheat the thawed casserole in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until it's heated through. If reheating individual portions, you can use a microwave, heating on medium power for 1-2 minutes, checking and stirring halfway through.
For an extra touch of freshness, consider adding a drizzle of maple syrup or a sprinkle of powdered sugar before serving. This will enhance the flavors and make the reheated casserole taste just as delightful as when it was freshly baked.
