Blueberry French Toast Casserole transforms your busiest mornings into something special – no flipping, no standing over the stove, just pure breakfast bliss. I still remember the first time I served this at a family brunch; my daughter looked up and said, “Mom, this tastes like dessert for breakfast!”
Back in my grandmother’s farmhouse kitchen, Sunday mornings meant the whole family gathered around one big table. She’d always say the best breakfasts were the ones that let you sit down with everyone instead of cooking while they ate. This casserole carries that same spirit – prep it Saturday night, pop it in the oven Sunday morning, and join your family at the table while your kitchen fills with the scent of cinnamon, vanilla, and sweet blueberries bubbling away. The cream cheese layer melts into pockets of creamy goodness that remind me of the cheese danish my grandma used to make, but easier and feeding a crowd. Time to get our hands floury!
Why Blueberry French Toast Casserole Belongs in Your Recipe Box
I’ve been making breakfast casseroles for over thirty years, and this blueberry version has earned its place as my go-to for everything from Christmas morning to lazy Saturday brunches.

Perfect texture every time – custardy center with golden, slightly crisp edges
What Goes Into This Blueberry French Toast Casserole
French bread forms the foundation of this dish, and I always choose a wide loaf that’s a day or two old – slightly stale bread soaks up that custard mixture without turning mushy, giving you the perfect texture balance.
Cream cheese creates those dreamy pockets of richness throughout the casserole; make sure it’s fully softened so it mixes smoothly with the powdered sugar – I leave mine on the counter for about an hour before I start.
Blueberries bring fresh, bright flavor and beautiful color; I use them in two layers so every bite has fruit, and frozen berries work perfectly well without needing to thaw them first.
Eggs bind everything together into that classic French toast custard – eight whole eggs might seem like a lot, but they’re what transforms bread cubes into something truly special.
Cinnamon and nutmeg add warmth and depth; in my kitchen, I prefer freshly ground nutmeg when I have it because the flavor is noticeably brighter and more aromatic.
Milk helps create the custard base, and whole milk gives you the richest result, though I’ve used 2% many times with great success.
Powdered sugar sweetens the cream cheese layer without adding graininess – it dissolves completely for that smooth, sweet filling.
Vanilla extract appears in both the cream cheese and custard mixtures, building layers of flavor that make this casserole taste like something from a fancy brunch spot.
How to Make Blueberry French Toast Casserole Step by Step
Step 1. I’ve learned that buttering your 10×14-inch baking dish before you start prevents any sticking and makes cleanup easier – don’t skip this simple step.
Step 2. Beat together the softened cream cheese, powdered sugar, 2 tablespoons milk, and 1 teaspoon vanilla until completely smooth; after years of making this, I know any lumps now mean lumps later, so take your time.
Step 3. Gently fold 1 cup of blueberries into the cream cheese mixture, being careful not to crush them – you want whole berries scattered throughout.
Step 4. Arrange half your bread cubes in an even layer on the bottom of the dish, then dollop and spread the cream cheese mixture over them, and top with the remaining bread cubes.
Step 5.Whisk together 2 cups milk, 8 eggs, 2 teaspoons vanilla, cinnamon, and nutmeg until well combined – I whisk for a good 30 seconds to make sure everything’s fully incorporated.
Step 6. Pour the egg mixture slowly over the bread layers, pressing down gently with a spatula to help the bread soak it up, then scatter the remaining cup of blueberries on top.
Step 7. Cover tightly with foil and refrigerate for at least 8 hours or overnight; Betty’s tip: remove it from the fridge 30-60 minutes before baking so it comes closer to room temperature for even cooking.
Step 8. Bake covered at 375°F for 45 minutes, then remove the foil and continue baking for about 30 more minutes until the center is set and the top is golden brown – total time is around 75 minutes.
Step 9. Let the casserole rest for 10 minutes after baking; I’ve found this resting time lets everything set up perfectly so your portions hold their shape when you serve them.
Keeping This Blueberry French Toast Casserole Fresh
I typically store leftovers in an airtight container in the refrigerator for up to 3 days, though honestly, in my house, it rarely lasts that long. The casserole stays moist and flavorful, making it perfect for quick weekday breakfasts – just reheat and enjoy.
Betty’s freezing method works beautifully for this recipe. You can freeze the unbaked casserole for up to 2 months by wrapping it tightly in plastic wrap and then foil, or freeze individual baked portions for up to a month. I often make two casseroles at once – one to bake immediately and one to freeze for a future busy morning. When freezing unbaked, let it thaw in the refrigerator overnight before baking as directed.
For the best texture, I reheat individual portions in the microwave for 1-2 minutes, or warm the entire casserole in a 325°F oven for 15-20 minutes covered with foil. The oven method keeps that nice texture on top while warming it through evenly. My family actually loves the leftovers almost as much as the fresh-baked casserole – the flavors seem to meld even more after a day in the fridge.
Overnight Blueberry French Toast Casserole
A make-ahead breakfast casserole with layers of French bread, cream cheese, and blueberries soaked in cinnamon custard. Perfect for holiday mornings and weekend brunches.
In a mixing bowl, beat together the softened cream cheese, powdered sugar, 2 tablespoons milk, and 1 teaspoon vanilla extract until completely smooth.
Gently fold 1 cup of blueberries into the cream cheese mixture.
Layer half of the bread cubes in the bottom of the prepared baking dish. Spread the cream cheese mixture evenly over the bread. Top with the remaining bread cubes.
In a large bowl, whisk together 2 cups milk, eggs, remaining 2 teaspoons vanilla extract, cinnamon, and nutmeg until fully combined.
Pour the egg mixture slowly over the bread layers, pressing down gently with a spatula to help absorption. Sprinkle remaining 1 cup of blueberries evenly on top.
Cover tightly with aluminum foil and refrigerate for 8 hours or overnight. Remove from refrigerator 30-60 minutes before baking.
Preheat oven to 375°F (190°C).
Bake covered with foil for 45 minutes. Remove foil and continue baking for 30 more minutes until center is set and top is golden brown.
Let rest for 10 minutes before serving. Serve with maple syrup if desired.
Notes
Use day-old French bread for better absorption. Can substitute challah or brioche. Frozen blueberries work well without thawing. Store leftovers covered in refrigerator for up to 3 days. Can freeze unbaked for 2 months or baked portions for 1 month.
Perfect Partners for Blueberry French Toast Casserole
Crispy bacon or breakfast sausage provides that essential savory balance to the sweet casserole; the salty, meaty flavors cut through the richness and create a complete breakfast plate that satisfies every craving.
Fresh fruit salad with strawberries, raspberries, and melon adds brightness and freshness; I love serving a big bowl of colorful fruit alongside this rich casserole, especially in summer when berries are at their peak.
Hash browns or breakfast potatoes round out the meal for heartier appetites; crispy potatoes seasoned with a little salt and pepper complement the sweet casserole beautifully and make it feel like a full brunch spread.
Hot coffee and fresh orange juice are my go-to beverages; there’s something about that combination that just feels right with a leisurely weekend breakfast, especially when you’re gathered around the table with family.
Whipped cream or vanilla yogurt on the side lets everyone customize their serving; some folks in my family love a dollop of barely sweetened whipped cream, while others prefer a spoonful of creamy Greek yogurt for a tangy contrast.
Maple syrup for drizzling is essential for those who want their Blueberry French Toast Casserole extra sweet; warm the syrup slightly and let everyone drizzle as much as they like over their portion.
FAQs
Can I use frozen blueberries instead of fresh? I recommend using frozen blueberries straight from the freezer without thawing – they work perfectly and actually release less juice during baking, preventing a soggy casserole.
What if I don’t have French bread? Many home cooks find success with challah, brioche, or even thick-sliced white bread; the key is using something sturdy enough to soak up the custard without falling apart completely.
Can I make this the same morning instead of overnight? To prevent a mushy texture, you’ll need to let it soak for at least 30-45 minutes before baking; the overnight method gives better results, but a same-morning version works when you’re pressed for time.
How do I know when the casserole is fully cooked? The best approach I’ve tested is inserting a knife in the center – it should come out mostly clean with just a few moist crumbs, and the top should be golden brown with the center no longer jiggly.
Can I substitute the cream cheese? Betty’s solution is using mascarpone for an even richer result, or ricotta cheese mixed with a little extra powdered sugar for a lighter texture; both work beautifully in this recipe.
How do I prevent the top from burning during the long bake time? I’ve learned that keeping the foil on for the first 45 minutes protects the top, and if it’s browning too quickly in the final 30 minutes, tent it loosely with foil again.
