How to Store or Freeze This Recipe
- To store the overnight blueberry French toast casserole, first allow it to cool completely at room temperature. This helps prevent condensation, which can make the bread soggy.
- Once cooled, cover the casserole tightly with plastic wrap or transfer it to an airtight container. This will help maintain its freshness and prevent it from absorbing any unwanted odors from the refrigerator.
- For short-term storage, place the covered casserole in the refrigerator. It will stay fresh for up to 3-4 days. When you're ready to enjoy it again, simply reheat individual portions in the microwave or warm the entire dish in the oven at 350°F (175°C) until heated through.
- If you wish to freeze the casserole, wrap it tightly in aluminum foil and then place it in a large, resealable freezer bag. This double layer of protection helps prevent freezer burn and keeps the casserole tasting fresh.
- Label the freezer bag with the date and contents to keep track of its storage time. The casserole can be frozen for up to 2-3 months.
- When you're ready to enjoy the frozen casserole, transfer it from the freezer to the refrigerator the night before to allow it to thaw slowly and evenly.
- Once thawed, reheat the casserole in the oven at 350°F (175°C) for about 20-30 minutes, or until it is heated through and the top is slightly crispy.
- For an extra touch of freshness, consider adding a handful of fresh blueberries or a drizzle of maple syrup just before serving. This will enhance the flavors and make the dish feel freshly made.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover overnight blueberry french toast casserole in an oven-safe dish. Cover it with foil to prevent it from drying out. Bake for 20-25 minutes, or until heated through.
For a quicker method, use the microwave. Place a portion of the casserole on a microwave-safe plate. Cover it with a microwave-safe cover or a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking and stirring halfway through to ensure even heating.
If you prefer a crispy top, use a toaster oven. Preheat the toaster oven to 350°F (175°C). Place a portion of the casserole on a toaster oven-safe tray. Heat for 10-15 minutes, or until warmed through and the top is slightly crispy.
For a stovetop method, heat a non-stick skillet over medium heat. Add a small amount of butter or oil to the skillet. Place a portion of the casserole in the skillet and cover with a lid. Heat for 5-7 minutes, flipping halfway through, until warmed through and slightly crispy on the outside.
