The Origins of French Toast Casseroles

Early Beginnings of French Toast

French toast dates back to ancient Rome. People made a dish called “pan dulcis” by soaking stale bread in milk and eggs before frying it. This method helped use up leftover bread and became a popular practice throughout Europe.

Evolution into Casseroles

In the 20th century, French toast casseroles began to appear in the United States. As casseroles became popular, cooks started baking French toast in large dishes. This new approach made the dish easier to prepare for large groups, especially during holidays and brunch.

Why They Became Popular

French toast casseroles became a holiday and brunch favorite because of their convenience. You could prepare them ahead of time and bake them in the morning, saving time. Over the years, they gained popularity for their ease and versatility.

Today, people enjoy French toast casseroles, especially with brioche, as a go-to dish for festive breakfasts and brunches.

Why Brioche is Perfect for French Toast Casserole

Brioche is the perfect bread for French toast casserole due to its rich, buttery texture and subtle sweetness. Unlike traditional bread, brioche has a soft, airy crumb and a slightly sweet flavor that complements the custard mixture used in casseroles. Its high egg and butter content give it a tender, melt-in-your-mouth quality, which results in a deliciously soft interior when baked.

The richness of brioche allows it to soak up the custard without becoming soggy, making it ideal for casseroles that require a balance of crispy and soft textures. When baked, the edges of the brioche form a golden, slightly crispy crust, while the inside remains perfectly moist and fluffy.

Brioche’s sweetness also adds a touch of indulgence to the dish, making it a special treat for breakfast or brunch. This combination of texture and flavor is what makes brioche the go-to bread for French toast casseroles.

Why Brioche Bread: Characteristics and Benefits

Brioche is the star of French toast casserole, offering unique qualities that elevate the dish. Its rich, buttery texture makes it perfect for soaking up the custard mixture without becoming soggy. The bread’s slightly sweet flavor complements the custard’s savory elements, creating a harmonious balance. The soft, airy crumb and high egg and butter content make brioche tender and indulgent, while the golden, slightly crispy crust that forms when baked adds a delightful contrast to the soft interior.

Essential Ingredients: Eggs, Milk, Cinnamon, etc.

The custard mixture that binds the casserole together is made up of eggs, milk, and a bit of sugar. Eggs provide richness and help the casserole set as it bakes. Milk (or a dairy alternative) adds creaminess and moisture, ensuring the dish remains tender. Cinnamon and vanilla extract bring warmth and depth of flavor, making each bite irresistibly fragrant. Together, these ingredients create a custard that perfectly complements the brioche bread.

Optional Add-ins: Fruits, Nuts, Chocolate Chips

For added flavor and texture, you can mix in optional add-ins like fresh berries, sliced bananas, or chopped apples. These fruits add a burst of freshness and natural sweetness. Nuts, such as walnuts or pecans, introduce a crunchy element, while chocolate chips can turn the casserole into a more decadent treat. These add-ins allow you to personalize the casserole, tailoring it to your preferences or dietary needs. Whether you stick with the classic combination or get creative, the ingredients come together to make a rich and comforting dish.

How to Cut the Brioche Bread for Casserole: Step-by-Step Guide

Select the Right Brioche Bread
- Choose a fresh, soft loaf of brioche. For best results, avoid using bread that is too fresh, as slightly stale brioche holds up better when soaked in the custard.
Decide on the Cut Style
- You can either slice or cube the brioche:
  - Slicing: Cut the brioche into 1-inch thick slices. This is the most common method and provides a traditional look with substantial slices that absorb the custard evenly.
  - Cubing: For a more rustic appearance, cut the bread into 1 to 1.5-inch cubes. This works well for a casserole that will have a more uniform custard soak and is easier to serve in individual portions.
Use a Serrated Knife
- When cutting the brioche, always use a serrated knife to prevent squashing the bread. The knife will slice through the soft texture of the brioche without compressing it.
Let the Bread Dry Slightly (Optional)
- If you’re preparing the casserole in advance, you can leave the sliced or cubed bread out overnight to dry slightly. This step helps the bread absorb the custard without becoming too soggy.
Cut the Bread into Even Pieces
- Whether slicing or cubing, make sure the pieces are as even as possible. Uniform pieces ensure that the bread will soak the custard evenly, creating a consistent texture throughout the casserole.
Prepare for Soaking
- Once your brioche is cut, you’re ready to soak it in the custard mixture. The size and cut of your bread will affect how much custard it soaks up, so aim for an even distribution of bread pieces in the casserole dish for the best results.

By following these steps, you’ll have the perfect base for your Brioche French Toast Casserole, with evenly cut pieces that soak up the custard for a rich and delicious breakfast or brunch dish.

Variations of Brioche French Toast Casserole

Brioche French Toast Casserole is a versatile dish that can be adapted to suit different tastes and dietary preferences. Whether you’re in the mood for something savory, looking for a vegan version, or need a gluten-free option, there are plenty of variations that can be made. Here’s a look at some popular twists on this classic casserole.

1. Savory Brioche French Toast Casserole

For those who prefer savory dishes, Savory Brioche French Toast Casserole offers a unique and delicious alternative to the traditional sweet version. The rich, buttery flavor of brioche pairs beautifully with savory ingredients, making it an ideal choice for brunch or dinner. Here’s how you can make this savory variation:

Meats: Start by adding crispy bacon or sausage to the casserole for a rich, salty flavor. You can cook the bacon or sausage beforehand, then chop them into bite-sized pieces and mix them into the custard. Alternatively, ham or chorizo can also be used for a different flavor profile.
Cheese: To bring creaminess and depth to the casserole, add shredded cheddar, Gruyère, or mozzarella. The cheese melts beautifully into the bread, making the casserole gooey and flavorful.
Vegetables: For an added layer of freshness and flavor, consider adding spinach, onions, or mushrooms. These vegetables complement the richness of the bread and meat and provide a nice balance to the dish.
Herbs and Spices: To enhance the savory notes, season your casserole with garlic, thyme, rosemary, or black pepper. These herbs bring out the savory flavors without overwhelming the dish.

This savory version is perfect for those who enjoy the comforting, rich taste of French toast but want to skip the sweetness. It’s a fantastic option for breakfast, lunch, or dinner.

2. Vegan Brioche French Toast Casserole (Substitutions)

If you’re following a vegan diet, you can still enjoy the delicious flavors of Brioche French Toast Casserole by making some simple substitutions for the eggs, milk, and butter. Here’s how to make a Vegan Brioche French Toast Casserole that’s just as satisfying as the original:

Brioche: Traditional brioche contains butter and eggs, but you can substitute it with vegan brioche or plant-based bread. There are many vegan-friendly bread options available, or you can make your own using vegan butter and flaxseeds or chia seeds as egg replacements.
Egg Substitute: For the egg mixture, replace eggs with a flaxseed egg or chia egg. To make a flaxseed egg, mix 1 tablespoon of ground flaxseeds with 2.5 tablespoons of water and let it sit for 5 minutes until it becomes gel-like. Another option is using silken tofu blended with some almond milk as a creamy base.
Milk Substitute: Instead of dairy milk, use any plant-based milk such as almond milk, soy milk, or oat milk. These alternatives provide a similar consistency and flavor without the use of dairy.
Butter Substitute: Use vegan butter or coconut oil in place of regular butter to maintain the richness of the casserole. Alternatively, olive oil can also work if you want a lighter option.
Sweeteners: If you want to add a little sweetness to the vegan casserole, you can use maple syrup or agave syrup instead of honey or granulated sugar.

By swapping out the non-vegan ingredients with plant-based alternatives, you can enjoy a delicious Vegan Brioche French Toast Casserole that’s rich in flavor and perfect for those following a vegan lifestyle.

3. Gluten-Free Brioche French Toast Casserole

For those who follow a gluten-free diet, you can still enjoy a delightful Brioche French Toast Casserole with a few simple modifications. Here’s how to make a Gluten-Free Brioche French Toast Casserole:

Gluten-Free Brioche: Finding gluten-free brioche can be a challenge, but there are many gluten-free breads on the market that can serve as a great substitute. Look for breads that are rich and soft, similar to traditional brioche, such as gluten-free challah or gluten-free brioche bread. If you prefer to make your own, use a gluten-free flour blend that is designed to mimic the texture and flavor of brioche.
Egg Mixture: The egg mixture for a gluten-free casserole should be the same as for the traditional version, using eggs (or egg substitute if vegan) and milk. If you’re making a vegan version, simply follow the same guidelines as for the vegan casserole.
Toppings and Add-ins: When it comes to add-ins, you can use the same ingredients as for the original casserole. Add fruits, nuts, or chocolate chips—just make sure that any pre-packaged ingredients, like chocolate chips, are gluten-free.
Baking Tips: Gluten-free bread may absorb liquid differently than traditional bread, so be sure to let the bread soak for a little longer to ensure the custard fully soaks into the bread. Also, check your casserole halfway through baking to make sure it’s baking evenly. If the top is browning too quickly, cover it loosely with aluminum foil and continue baking.

With these modifications, your Gluten-Free Brioche French Toast Casserole will have the same soft, buttery texture and delicious flavor as the traditional dish, but without the gluten.
