Sturdy bread is essential, so avoid soft sandwich bread unless you dry it briefly in the oven. Frozen blueberries can be used without thawing they help prevent the casserole from turning purple too soon.

Honey oat bread, croissant bread, or sourdough all bring a slightly different flavor but remain delicious.
Step-by-Step Instructions
Step 1 – Prepare the Bread and Pan
Grease a 9×13-inch baking dish generously. Spread your cubed bread evenly across the dish, making sure to fill the corners so every bite gets soaked in custard. If your bread is still fresh, dry the cubes in a 300°F (149°C) oven for 8–10 minutes. This step makes the casserole firm, not soggy, especially helpful when preparing Breakfast Ideas Freezer-style.
Step 2 – Mix the Custard
In a large bowl, whisk eggs, milk, cream, sugar, cinnamon, vanilla, and salt until the mixture is completely smooth. Pour it slowly over the bread, and use a spatula to press the bread so it absorbs the custard evenly. Scatter blueberries across the top and gently push some into the bread layer. Cover the dish tightly and refrigerate for at least 3 hours or overnight for the richest texture.
Step 3 – Add Streusel and Bake
To make the streusel, combine flour, brown sugar, cinnamon, and salt in a bowl. Cut in the cold butter using two forks or your fingers until crumbly. When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the fridge, sprinkle the streusel evenly over the top, and bake for 45–55 minutes. The casserole is done when the center is set and the top turns golden-brown. Let it cool for 10 minutes before serving.
