Step‑by‑Step Instructions for French Toast Casserole Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). This warm temperature ensures that your French Toast Casserole cooks evenly, creating a lovely golden-brown crust while keeping the center soft and custardy. Make sure your oven is fully preheated before moving on to the next step, so your casserole bakes to perfection. Step 2: Prepare the Baking Dish While the oven heats up, take a 9×13-inch baking dish and grease it generously with unsalted butter or nonstick spray. This step is crucial for preventing the French Toast Casserole from sticking and ensures that every slice comes out easily. A well-greased dish will also promote a beautiful golden top as it bakes. Step 3: Assemble the Bread Base Next, evenly distribute the 1-inch bread cubes (brioche, challah, or French bread) across the prepared baking dish. Spread them out as much as possible, filling the dish to create a solid foundation for your casserole. If you’re using slightly stale bread, this will absorb the custard mixture beautifully, yielding that desired cozy texture. Step 4: Whisk the Egg Mixture In a large mixing bowl, whisk together the 6 large eggs, 2 cups of whole milk, 1/2 cup of granulated sugar, 1 tablespoon of vanilla extract, 1 teaspoon of ground cinnamon, and 1/4 teaspoon of salt until well combined and frothy. This mixture will bind the casserole and infuse it with delicious flavors. Look for a smooth, uniform texture before continuing. Step 5: Pour the Mixture Pour the egg mixture evenly over the bread cubes in the baking dish, ensuring all pieces are well-coated. Use a spatula to gently press down the bread, allowing it to soak up the custard mixture. This process is key to achieving that rich, custardy interior that makes the French Toast Casserole so delightful. Step 6: Add the Butter Drizzle the 1/2 cup of melted unsalted butter evenly over the top of the casserole. This will create a wonderfully rich flavor and help the tops of the bread cubes become crispy and golden. Let the casserole sit for about 10 minutes to allow the bread to absorb more of the custard before baking. Step 7: Bake the Casserole Place the baking dish in the preheated oven and bake uncovered for 40 minutes. Keep an eye on it; the casserole is done when the top is golden brown, and a toothpick inserted in the center comes out clean. The inviting aroma will fill your kitchen, tempting everyone to gather around and enjoy the deliciousness. Step 8: Serve and Enjoy Once baked, remove the casserole from the oven and let it cool for a few minutes before slicing. Serve warm, topped with maple syrup, a dusting of powdered sugar, or fresh fruit. This Ultimate Make-Ahead French Toast Casserole is perfect for leisurely mornings or festive brunch gatherings, ready to warm hearts and bellies alike! How to Store and Freeze French Toast Casserole Fridge: Store any leftovers in an airtight container for up to 4 days to keep the casserole fresh and maintain its wonderful texture. Freezer: Slice and wrap the French Toast Casserole in plastic wrap, then place it in a freezer-safe bag for up to 3 months; this makes it easy to enjoy later! Reheating: For best results, reheat slices covered with foil in the oven at 350°F for about 15 minutes, allowing it to regain its custardy appeal. Cool Before Storing: Always ensure the casserole is completely cooled before refrigerating or freezing; this helps prevent sogginess and keeps flavors intact.

Expert Tips for Perfect French Toast Casserole Bread Matters: Use slightly stale brioche or challah to maintain structure and prevent sogginess. Fresh bread can make it too mushy. Soak It Right: For the best flavor and texture, let the casserole soak overnight in the fridge, allowing the bread to absorb the custard fully. Bake It Covered: If you prefer a softer top, cover the casserole with foil for the first 20 minutes of baking, then remove to crisp it up. Sweetness Control: Adjust the sugar to your liking; opt for fresh fruit toppings like berries or yogurt for a less sweet but delicious experience. Reheat Gently: To enjoy leftovers, cover with foil and reheat at 350°F for about 15 minutes—this keeps the French Toast Casserole tender and tasty. Make Ahead Options These Ultimate Make-Ahead French Toast Casserole preparations are perfect for busy mornings and make meal planning a breeze! You can prepare the entire casserole up to 24 hours in advance by following the assembly instructions and refrigerating it overnight. While prepping, ensure that the bread cubes are well-soaked in the custard mixture to prevent them from drying out. To maintain quality, cover the dish tightly with plastic wrap or foil. When you’re ready to bake, simply remove it from the fridge and let it sit at room temperature for about 30 minutes, then bake as directed. You’ll have a delicious, comforting breakfast ready to impress with minimal morning effort! French Toast Casserole Recipe FAQs What type of bread is best for French Toast Casserole? For the best results, I recommend using slightly stale brioche or challah bread cut into 1-inch cubes. These types of bread provide a sturdy base that absorbs the custard without becoming too mushy.

You can store any leftover French Toast Casserole in an airtight container in the refrigerator for up to 4 days. Be sure to allow it to cool completely before putting it away to maintain its texture and flavor. Can I freeze French Toast Casserole? Yes, indeed!
