Now, let’s talk ingredients!
Ingredients
-
1 loaf of bread (preferably brioche or challah): The heart of this dish! Brioche is rich and buttery while challah adds a slightly sweet flavor. You want a loaf that can soak up all that creamy custard goodness without falling apart.
-
4 large eggs: Essential for that custardy texture. They act as the glue that holds all the deliciousness together.
-
2 cups milk: I find whole milk gives the best creaminess, but feel free to use low-fat or a non-dairy milk alternative if you lean that way.
-
1/2 cup heavy cream: This is where the magic happens! The heavy cream adds richness to the custard, resulting in a creamy, dreamy end product.
-
1/4 cup granulated sugar: Just the right amount to sweeten things up without overpowering the dish.
-
1 teaspoon vanilla extract: Adds a lovely aromatic note that complements the cinnamon beautifully—trust me, it makes a world of difference!
-
1 teaspoon ground cinnamon: Oh, the warm spice that fills the air and makes everything feel like a cozy morning. You can even add nutmeg for a twist!
-
1 cup strawberries (sliced): Fresh berries bring a burst of flavor and color. Strawberries add sweetness, but feel free to use mixed berries for added texture and tartness.
-
1 cup blueberries: These little gems add their own sweetness and a pop of color, looking all cute nestled into that casserole.
-
Butter (for greasing the dish): Nobody likes a sticking situation, so a little butter ensures that everything comes out effortlessly.
-
Maple syrup (for serving): Because what’s French toast without that sweet drizzle of maple goodness?
Now that you have all your ingredients lined up, let’s get you cooking!
How to Make It Step-by-Step
Let’s dive into the process! I’ll walk you through the steps with my own personal quirks and hints to make your experience as smooth as possible.
Step 1: Grease the Baking Dish
Start by taking that trusty 9×13 inch baking dish and giving it a generous coat of butter. The sound of the butter scraping against the dish? Heaven! Just imagine how well this will prevent sticking. No one wants to deal with broken casserole pieces when serving—talk about a breakfast disaster!
Step 2: Cut the Bread
Now, grab that loaf of brioche or challah and cut it into cubes. I usually aim for about 1-inch pieces, but let’s be real, they don’t have to be perfect cubes. Embrace the chaos! Just make sure they’re manageable in size. Place them in your greased baking dish, creating a cozy bread nest.
Step 3: Whisk the Custard Mixture
In a large bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, and cinnamon. Oh, the colors blend together beautifully! Each ingredient does its little dance as you whisk. I love to savor that sweet smell of vanilla and cinnamon wafting through the air. Just don’t forget to scrape the sides of the bowl to get all that sugar incorporated!
Step 4: Pour Over the Bread
Pour the custard mixture over the bread cubes, making sure every last piece gets a good soak. You can use a spoon to gently push down any bread that’s floating, ensuring it’s all covered. You want every piece of bread to be beautifully coated; otherwise, you’ll have some dry bites later on, and nobody wants that disappointment!
Step 5: Add Berries
Now comes the fun part! Layer the sliced strawberries and blueberries on top of the bread mixture. This is where you can let your creativity flow. I usually do a pattern, you know, because why not make it look pretty? At this point, I always end up sneaking a few berries into my mouth. Oops…
Step 6: Chill Overnight
Cover your dish tightly with plastic wrap and refrigerate it overnight. Overnight magic happens here! All those flavors blend together, and the bread soaks up the custard. Sleep tight and dream of your glorious breakfast!
Step 7: Preheat the Oven
The next morning, about 30 minutes before you’re ready to bake, take your casserole out of the fridge and let it sit at room temperature. In the meantime, preheat your oven to 350°F (175°C). Feel free to pour yourself a cup of coffee for that much-needed morning boost!
Step 8: Bake It Up
Remove the casserole from its chilly home and bake it for 45-50 minutes, or until the top is nicely golden brown and the egg is set. The aroma wafting through your home will be enough to make anyone’s stomach growl! Give it a little jiggle, and if the middle isn’t too wobbly, you’re golden.
Step 9: Cool and Serve
Once it’s out of the oven, let it cool for about five minutes—not too long though! Just enough so you don’t burn your tongue like I tend to do. Serve warm, drizzled with maple syrup, and watch the smiles spread across everyone’s faces as they dig in!
Each layer deeply embodies warmth and comfort, and the sweetness from the fruits will transport you to a happy place, even on a busy weekday.
Tips for Best Results
-
Stale Bread is Your Friend: If you have leftover bread that’s a little too stale, use it! It will soak up the custard better, improving the texture.
-
Don’t Skip the Rest Time: It may be tempting to rush the process, but letting it soak overnight creates a dreamy consistency.
-
Adjust the Sweetness: If you’re sensitive to sweetness, adjust the sugar in the custard to your taste. You can always serve it with syrup on the side!
-
Check for Doneness: Ovens vary, so keep an eye on yours as it bakes to avoid a burnt breakfast.
-
Play with Flavors: You can toss in a splash of orange juice or zest for an unexpected citrus twist, or swap the cinnamon for nutmeg for a different spice vibe.
Ingredient Substitutions & Variations
-
Bread: Feel free to try other breads like sourdough or whole wheat for added nuttiness and flavor.
-
Dairy Alternatives: Use almond milk or oat milk instead of cow’s milk and coconut cream instead of heavy cream for a vegan version.
-
Fruit Upgrades: Seasonal fruits are fabulous! Try peaches, apples, or even bananas for a fruity twist.

Honestly, a good rom-com playing in the background while you dig into this breakfast is perfection! If you want to add a side dish, fluffy scrambled eggs or crispy hash browns make perfect companions.
How to Store and Reheat Leftovers
If you find yourself lucky enough to have leftovers, store them in an airtight container in the fridge. When it’s time to reheat, just pop it in the microwave for 30-60 seconds. I’d recommend adding a splash of milk before reheating to maintain that lovely moist texture. Avoid the oven unless you want to wait—you won’t want to lose any more of those cozy vibes!
Make-Ahead and Freezer Tips
You can absolutely keep the assembled casserole in the freezer before baking. Just ensure it’s tightly wrapped in plastic and aluminum foil to prevent freezer burn. When you’re ready to bake it, allow it to thaw in the fridge overnight before baking as usual.
Common Mistakes to Avoid
-
Don’t Use Fresh Bread: Fresh bread may not soak up the custard effectively. A day or two old is ideal!
-
Too Much Sugar: Taste the custard before pouring it over the bread. Remember, you can always adjust it.
-
Overbaking: Settling for dry casserole is the worst! Keep an eye on it and make sure the top is nicely set but not overly brown.
