To enhance the flavor of this overnight blueberry French toast casserole, consider using a mix of fresh and frozen blueberries. The fresh blueberries will provide a burst of flavor and a slight tartness, while the frozen ones will release their juices as they thaw, creating a delightful syrupy texture throughout the casserole. Additionally, for a richer taste, try using a brioche or challah bread instead of the standard French bread. These breads have a slightly sweet and buttery flavor that complements the egg mixture beautifully.

• For short-term storage, cover the casserole tightly with plastic wrap or transfer it to an airtight container. Store it in the refrigerator for up to 3-4 days. This keeps the blueberries fresh and the bread from drying out.

• If you plan to enjoy the casserole later, freezing is a fantastic option. Slice the casserole into individual portions for easy reheating. Wrap each portion in plastic wrap, then in aluminum foil to prevent freezer burn.

• Place the wrapped portions in a freezer-safe bag or container, labeling it with the date. This helps you keep track of freshness. The casserole can be frozen for up to 2 months.

• When you're ready to indulge, thaw the casserole in the refrigerator overnight. This gradual thawing preserves the texture and flavor of the blueberries and bread.

• To reheat, preheat your oven to 350°F (175°C). Remove the plastic wrap and foil, then place the casserole on a baking sheet. Cover it loosely with foil to prevent over-browning and bake for 15-20 minutes or until heated through.

• For a quicker option, use the microwave. Place a portion on a microwave-safe plate, cover with a damp paper towel, and heat on medium power in 30-second intervals until warm. This method is perfect for busy mornings when you crave a quick breakfast treat.

• Enhance the reheated casserole with a drizzle of maple syrup or a dusting of powdered sugar for an extra touch of sweetness.

• Preheat your oven to 350°F (175°C). Place the leftover casserole in an oven-safe dish, cover it with aluminum foil to prevent it from drying out, and bake for about 20-25 minutes until it's heated through and the blueberries are juicy and warm.

• For an extra indulgent twist, reheat the casserole on the stovetop. Melt a small amount of butter in a non-stick skillet over medium heat. Add a slice of the casserole and cook for about 3-4 minutes on each side until it's heated through and has a slightly crispy exterior.

• If you have an air fryer, set it to 350°F (175°C) and place a slice of the casserole in the basket. Heat for about 5-7 minutes, which will give you a warm inside and a delightfully crispy top.
