Ingredients

• 8 cups cubed brioche or challah bread (day-old works great)
• 2 cups fresh or frozen blueberries
• 6 large eggs, beaten
• 2 cups whole milk (or almond milk for a lighter twist)
• 1 cup heavy cream (or Greek yogurt for a Healthy Breakfast Casserole)
• ¾ cup granulated sugar
• 2 tsp pure vanilla extract
• 1 tsp ground cinnamon
• ¼ tsp salt
• Zest of 1 lemon (adds a bright pop!)
• 2 tbsp melted butter (plus extra for greasing)
• Maple syrup and powdered sugar, for serving

Instructions

1. Grease a 9×13-inch baking dish with butter or nonstick spray. Preheating the oven to 350°F (175°C) ensures even baking.
2. Arrange half the bread cubes in the dish. Scatter half the blueberries over the bread to create a fruity layer.
3. In a large bowl, whisk eggs, milk, cream, sugar, vanilla, cinnamon, salt, lemon zest, and melted butter until smooth.
4. Pour half the custard mixture over the bread and berries. Press the bread gently so it soaks up the liquid—this is key for a custardy center.
5. Layer the remaining bread and blueberries on top. Pour the rest of the custard over everything, ensuring every cube gets coated.
6. Cover with foil and let it sit at room temperature for 30 minutes. For a classic Breakfast Casserole Make Ahead or Breakfast Casserole Overnight twist, refrigerate up to 12 hours.
7. Bake covered for 30 minutes. Remove the foil, then bake an additional 15–20 minutes until the top turns golden brown and the center sets.
8. Let it rest for 5–10 minutes. Serve warm with a dusting of powdered sugar and a drizzle of maple syrup.
9. Dig in! Trust me, this one rivals any Brunch Casserole or Egg Casserole Recipes you’ve tried before.
