This Wholesome Apple Cinnamon Breakfast Casserole walks that perfect line between indulgence and something that actually makes you feel good after you eat it. The apples get soft and jammy in the oven, the cinnamon fills your whole kitchen, and the base is hearty enough to keep you full until lunch.
For best texture, use day-old bread. If using fresh bread, toast cubes briefly. Let the casserole rest for 15 minutes before baking to allow custard to absorb. For a dairy-free version, use coconut oil and full-fat oat milk. For gluten-free, use sturdy gluten-free bread. The casserole can be assembled the night before and refrigerated. Leftovers keep for up to 4 days in the refrigerator or can be frozen for up to 3 months.
