Storage: Cover leftovers tightly and refrigerate for up to 3 days. Reheat individual portions in the microwave or oven until warm.
Substitutions: You can use fresh strawberries instead of frozen. If using fresh, consider reducing the baking time slightly as they release less water initially. Brioche or challah bread can also be used for a richer flavor.
Variations: Add a layer of caramel sauce between the bread and fruit for a salted caramel twist. Or, swap the apple pie spice for pumpkin pie spice in the fall.
Tips: For extra crispiness, let the baked French toast sit for a few minutes after removing from the oven to allow the custard to set further. Ensure the bread is stale or day-old for best absorption.
