Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the Casserole:
- Sturdy bread (like challah, brioche, or French bread)
- Eggs
- Milk and heavy cream (or dairy-free alternatives like almond milk and coconut cream)
- Vanilla extract
- Brown sugar
- Ground cinnamon
- Salt
- Butter (for greasing the pan)
Optional Toppings:
- Fresh fruit (berries, sliced bananas, sautéed apples)
- Powdered sugar
- Maple syrup
- Chopped nuts (pecans, walnuts, or almonds)
- Chocolate chips
Step-by-Step Instructions
Step 1: Prepare the Bread
Start by cutting your bread into 1-inch cubes. Arrange them evenly in a greased 9×13-inch baking dish. If your bread is fresh, consider letting it sit out for a few hours or lightly toasting it to dry it out slightly. This ensures the bread absorbs the custard mixture without becoming overly soggy.
Step 2: Make the Custard
In a large mixing bowl, whisk together eggs, milk, heavy cream, brown sugar, cinnamon, vanilla extract, and a pinch of salt until smooth and well combined. Pour this mixture evenly over the bread cubes in the baking dish, pressing down gently with a spatula to ensure all pieces are fully coated. Cover the dish with plastic wrap and refrigerate overnight (or for at least 6 hours). This allows the bread to soak up the custard, resulting in a soft, custardy interior.
Step 3: Bake
The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature while the oven heats up. Bake uncovered for 45-55 minutes, or until the top is golden brown and the center is set. To check for doneness, insert a knife or toothpick into the center—it should come out clean.
Step 4: Serve
Let the casserole cool for a few minutes before slicing and serving. Garnish with your favorite toppings, such as a dusting of powdered sugar, a drizzle of maple syrup, or a handful of fresh berries. For an extra indulgent touch, add a dollop of whipped cream or a sprinkle of chopped nuts.
Customization Ideas
This casserole is incredibly versatile and can be tailored to suit your taste preferences:
- Add Mix-Ins: Sprinkle chocolate chips, raisins, or dried cranberries into the casserole before refrigerating.
- Experiment with Spices: Add nutmeg or cardamom for a unique twist on the classic cinnamon flavor.
- Try Different Fruits: Layer sliced bananas, apples, or peaches on top before baking for added sweetness and texture.
- Go Nutty: Top with toasted pecans, walnuts, or almonds for a crunchy contrast to the soft casserole.
Serving Suggestions
- Garnish with Fresh Fruit: Top your casserole with fresh berries, sliced bananas, or sautéed apples for a burst of color and flavor.
- Drizzle with Syrup: A generous pour of maple syrup adds an irresistible sweetness that pairs perfectly with the custardy texture.
- Pair with Breakfast Sides: Serve alongside crispy , sausage links, or scrambled eggs for a complete meal.
- Make It Festive: Add a sprinkle of powdered sugar or a dollop of whipped cream for a picture-perfect presentation.
- Create a Brunch Spread: Pair this casserole with quiches, fruit salads, or mimosas for an elegant brunch centerpiece.
Storage Tips
Refrigerating Leftovers:
Store any leftover casserole in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave for 30-40 seconds or place the entire casserole in the oven at 350°F (175°C) for 10-15 minutes until warmed through.
Freezing for Later:
If you want to prepare the casserole ahead of time, assemble it as instructed, cover it tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. When you’re ready to bake, thaw it overnight in the fridge and follow the regular baking instructions.
Reheating from Frozen:
To bake directly from frozen, increase the cooking time to 1 hour or until the casserole is completely heated through. Check for doneness by inserting a knife into the center—it should come out clean.
Frequently Asked Questions (FAQs)
1. Can I use any type of bread for this casserole?
Yes! Sturdy bread like challah, brioche, or French bread works best because it holds up well in the custard mixture. Day-old bread is ideal, but fresh bread can also be used if dried out slightly beforehand.
2. Can I make this casserole without eggs or dairy?
Absolutely! Substitute eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) and use plant-based milk like almond, soy, or oat milk. Replace heavy cream with coconut cream or another dairy-free alternative.
3. How far in advance can I prepare this casserole?
You can assemble the casserole up to 24 hours in advance and refrigerate it overnight. Alternatively, you can freeze it unbaked for up to 3 months.
4. Can I add toppings like chocolate chips, nuts, or fruit?
Yes! Add mix-ins like chocolate chips, nuts, or fresh fruit either before refrigerating or just before baking. These additions enhance flavor and texture.
5. What can I serve with this casserole?
Pair it with classic breakfast sides like sausage, scrambled eggs, or fruit salad. For a festive touch, serve it alongside quiches or mimosas.
6. How do I prevent the casserole from being too soggy?
Use slightly stale or dried-out bread to ensure it absorbs the custard without becoming overly mushy. Avoid over-soaking the bread by pressing it down gently during assembly.
7. Can I double the recipe for a larger crowd?
Yes, simply double the ingredients and bake in two separate dishes. Keep one dish warm in the oven at 200°F (95°C) while the other bakes.
8. How do I know when the casserole is done baking?
The casserole is done when the top is golden brown, the edges are crispy, and a knife inserted into the center comes out clean. This typically takes 45-55 minutes at 350°F (175°C).
9. Can I reheat leftovers without losing texture?
For best results, reheat individual portions in the oven at 350°F (175°C) for 10-15 minutes to restore crispiness. Avoid microwaving for too long, as it can make the casserole soggy.
10. Is this casserole kid-friendly?
Absolutely! Kids love the sweet, custardy texture and customizable toppings. You can adjust the amount of sugar or spices to suit their preferences.
