If you’re like me, mornings are a bit… well, unpredictable. That’s where breakfast ideas like this overnight blueberry French toast casserole come in. Prep it at night, pop it in the oven the next morning, and enjoy a slow start that smells like syrup and sweet bread. You’ll get the cozy satisfaction of a French breakfast without the 6 a.m. wakeup call.

I’ve made this casserole more times than I can count. It’s one of those easy French recipes that feels homemade, thoughtful, and comforting—without making you sprint around the kitchen. The egg custard gives the bread a soft center, the edges get just crispy enough, and the blueberries give it a tart, juicy pop in every bite.

3) Ingredients for Overnight Blueberry French Toast Casserole

French Bread: A crusty loaf is perfect here. It soaks up the custard while keeping its texture. If your bread’s a bit stale, even better.

Blueberries: You can use fresh or frozen. I don’t thaw frozen ones—straight into the dish they go, and they always bake up beautifully.

Cream Cheese: I cut it into cubes and layer it between the bread. It melts into creamy pockets that feel like a surprise in every bite.

Eggs: They’re the base of the custard. Eight large eggs create a rich and thick mix that holds the casserole together.

Milk: Whole milk works best. It balances the richness of the cream and keeps the custard smooth.

Heavy Cream: Adds that velvety texture. The result is soft, not soggy.

Maple Syrup: A little goes into the custard to bring a mellow sweetness. More can go on top at the table.

Vanilla Extract: It rounds out the flavors without taking over.

Ground Cinnamon: A half teaspoon is enough to make the whole kitchen smell like a bakery.

Salt: Just a pinch makes everything else pop.

4) How to Make Overnight Blueberry French Toast Casserole

Step 1. Grease a 9×13 inch baking dish. Spread half the bread cubes in the dish. Sprinkle half the blueberries and cream cheese over the bread. Repeat with the remaining bread, blueberries, and cream cheese.

Step 2. In a large bowl, whisk the eggs, milk, cream, maple syrup, vanilla, cinnamon, and salt until smooth.

Step 3. Pour the custard evenly over the bread mixture. Use a spatula or your hand to press the bread down gently so it absorbs the liquid.

Step 4. Cover the dish with foil or plastic wrap and chill it in the fridge overnight. This gives the bread time to soak up all the good stuff.

Step 5. In the morning, preheat your oven to 350°F. Take the casserole out of the fridge while the oven heats.

Step 6. Bake uncovered for 45 to 50 minutes. You want the top golden and the center set.

Step 7. Let it cool for about 10 minutes before serving. It’ll hold its shape better and be easier to slice.

5) Tips for Making Overnight Blueberry French Toast Casserole

Use good bread. Flimsy sandwich slices won’t hold up. A rustic French loaf gives structure and chew, even after soaking overnight.

Mix the custard thoroughly. Whisk until there are no streaks of yolk or cream. That helps the casserole bake evenly.

Don’t skip the resting time. The longer it sits before baking, the better the texture. I usually prep it at night and bake it fresh in the morning.

6) Making Overnight Blueberry French Toast Casserole Ahead of Time

This is one of my favorite breakfast ideas for house guests. You do all the work the night before. In the morning, it’s just bake and go. If you’re planning brunch, it’ll free you up for coffee and conversation instead of kitchen chaos.

Once you’ve assembled the casserole and poured the custard, wrap it tight and let it chill in the fridge. I’ve left it as long as 16 hours with no issues. In fact, it gets better.

If you’re really pressed for time, you can even bake it the night before and reheat individual portions. It won’t be quite as golden on top, but still tastes amazing.

7) Storing Leftover French Toast Casserole

Leftovers don’t last long in our house, but if you do have some, store them in an airtight container. They’ll keep in the fridge for 3 to 4 days.

To reheat, pop a slice in the microwave or warm it in a low oven. If it looks a little dry, drizzle a spoonful of maple syrup on top.

You can freeze individual portions too. Wrap them tightly and thaw in the fridge overnight before reheating. That makes weekday mornings feel just a bit fancier.
