Q1: Can I use frozen blueberries without thawing them first?

Yes! Just sprinkle them in frozen—they’ll thaw and bake beautifully without making the casserole soggy.

Q2: What’s the best bread if I don’t have French bread?

Challah, brioche, or even a crusty Italian loaf work great. Just avoid soft sandwich bread.

Q3: Can I make this casserole dairy-free or gluten-free?

Absolutely. Use almond or oat milk, plant-based cream cheese, and gluten-free bread. Baking time may vary slightly.

Q4: Can it be baked right after assembly instead of overnight?

While overnight soaking gives the best texture, you can bake it after letting it rest for 30–60 minutes if you’re short on time.

Instructions

In a bowl, mix softened cream cheese, powdered sugar, 2 tbsp milk, and 1 tsp vanilla until smooth. Fold in 1 cup blueberries.
Grease a 10×14-inch baking dish. Spread half of the cubed bread evenly across the bottom.
Spread the cream cheese mixture over the bread layer.
Top with the remaining bread cubes to form a second layer.
In a large bowl, whisk 2 cups milk, 8 eggs, remaining vanilla, cinnamon, and nutmeg. Pour over the bread.
Sprinkle the remaining 1 cup of blueberries evenly on top.
Cover with foil and refrigerate overnight (at least 8 hours).
Remove from fridge 30–60 minutes before baking. Preheat oven to 375°F (190°C).
Bake covered for 45 minutes. Remove foil and bake an additional 30 minutes until golden and center is set.
Let cool for 10 minutes before serving. Serve warm with maple syrup or berry compote if desired.

Notes

Use day-old or lightly toasted bread for best results.
Frozen blueberries can be used directly without thawing.
To freeze: wrap unbaked casserole tightly and freeze for up to 2 months.
Reheat leftovers in microwave or oven for a fresh-baked taste.
