What Is French Toast Casserole?

Table of Contents

French toast casserole is a baked breakfast dish that combines cubed bread with a sweet egg mixture. Unlike traditional French toast where you dip and cook each slice separately, this casserole method lets you prepare the entire dish at once. The bread soaks overnight in eggs, milk, and spices, then bakes into a golden, custardy breakfast that serves multiple people.

How to Make French Toast Casserole

Step 1: Prepare Your Baking Dish

Grease a 9×13 inch baking pan with butter or cooking spray. This prevents sticking and makes cleanup easier. You can also line the bottom with parchment paper for extra protection.

Step 2: Cut the Bread

Take your bread loaf and cut it into 1-inch cubes. You should have about 10-12 cups of bread cubes. Day-old bread works perfectly because it soaks up the egg mixture without getting too soggy. If your bread is fresh, leave the cubes out for 2-3 hours to dry slightly.

Step 3: Arrange Bread in Pan

Place all the bread cubes into your prepared baking dish. Spread them evenly so every piece gets coated with the egg mixture. Pack them loosely, not too tight.

Step 4: Mix the Custard

In a large mixing bowl, crack 8 eggs and whisk them well. Add the milk, heavy cream, both sugars, vanilla extract, cinnamon, nutmeg, and salt. Whisk everything together until the mixture is smooth and the sugar dissolves completely. This custard mixture is what makes your casserole soft and delicious.

Step 5: Pour Over Bread

Slowly pour the egg mixture over the bread cubes. Make sure you pour it evenly across the entire pan. Use a spatula or your hands to gently press the bread down into the liquid. Every piece should get soaked.

Step 6: Refrigerate Overnight

Cover the baking dish tightly with plastic wrap or aluminum foil. Place it in the refrigerator for at least 8 hours or overnight. This soaking time lets the bread absorb all the flavors and creates that perfect custardy texture.

Step 7: Make the Streusel Topping

The next morning, prepare your topping. In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Add the cold butter pieces and use a fork or your fingers to mix until the mixture looks like coarse crumbs. Stir in nuts if using.

Step 8: Add Topping and Bake

Remove the casserole from the refrigerator 20-30 minutes before baking. This brings it to room temperature. Preheat your oven to 350°F (175°C). Sprinkle the streusel topping evenly over the soaked bread. Bake uncovered for 45-55 minutes until the top is golden brown and the center is set. A knife inserted in the middle should come out mostly clean.

Step 9: Cool and Serve

Let the casserole cool for 5-10 minutes before serving. This helps it set properly and makes cutting easier. Cut into squares and serve warm.

Recipe Variations

Blueberry French Toast Casserole

Add 1.5 cups of fresh or frozen blueberries between the bread layers. The berries burst during baking and create delicious pockets of fruit flavor. You can also mix blueberries into the egg mixture before pouring.

Cream Cheese French Toast Bake

Cut 8 ounces of cream cheese into small cubes and scatter them among the bread pieces. The cream cheese melts during baking and creates creamy pockets throughout the dish. This version tastes similar to stuffed French toast.

Apple Cinnamon Casserole

Dice 2 large apples and layer them with the bread. Add extra cinnamon to the egg mixture (use 3 teaspoons total). Top with the streusel for an apple pie-inspired breakfast.

Chocolate Chip Version

Sprinkle 1 cup of chocolate chips over the bread before adding the egg mixture. Kids especially love this sweeter version that tastes like dessert for breakfast.

Pumpkin Spice French Toast Bake

Replace 1/2 cup of milk with pumpkin puree. Add 1 teaspoon of pumpkin pie spice to the egg mixture. This creates a perfect fall breakfast.

Savory French Toast Casserole

Skip the sugar and sweet spices. Instead, add 1 cup shredded cheese, cooked bacon or sausage, diced peppers, and onions. Season with salt, pepper, and herbs. This creates a breakfast strata that works for brunch or dinner.

Tips for Perfect French Toast Casserole

Bread Selection Matters

The type of bread you choose affects the final texture. French bread and challah are top choices because they have sturdy structures that hold up to soaking. Avoid thin sandwich bread as it becomes too mushy. The bread should be slightly stale or dried out – fresh bread absorbs too much liquid and turns soggy.

Soaking Time Is Important

Never skip the overnight soak. This step allows the bread to absorb the custard mixture fully. If you only soak for 1-2 hours, the casserole won’t have that signature custardy center. Plan ahead and prepare this dish the night before serving.

Oven Temperature Control

Bake at 350°F, not higher. A moderate temperature ensures the center cooks through without burning the top. If the top browns too quickly, cover it loosely with foil and continue baking until the center sets.

Check for Doneness

The casserole is ready when the center no longer jiggles and a knife comes out mostly clean (a few moist crumbs are okay). The internal temperature should reach 160°F. Overbaking makes it dry, so start checking around 45 minutes.

Make It Ahead

You can prepare the entire casserole up to 24 hours before baking. You can also freeze the unbaked casserole for up to 2 months. Thaw overnight in the refrigerator before baking.

Storage and Reheating

Refrigerator Storage

Leftover French toast casserole keeps well in the refrigerator for 3-4 days. Cover it tightly with plastic wrap or store in an airtight container. The flavors actually develop more after a day.

Freezing Instructions

Cut baked casserole into individual portions and wrap each piece in plastic wrap, then foil. Freeze for up to 2 months. Thaw in the refrigerator overnight.

Reheating Methods

Oven Method: Place portions in a baking dish, cover with foil, and heat at 350°F for 15-20 minutes.
Microwave Method: Heat individual portions for 60-90 seconds on medium power. This works for quick weekday breakfasts.
Air Fryer Method: Reheat at 350°F for 5-7 minutes. This makes the top crispy again.

Common Mistakes to Avoid

Using Too Much Liquid

If your casserole turns out soggy, you used too much liquid or too soft bread. Stick to the measurements and use sturdy bread. The liquid should just cover the bread, not flood it.

Skipping the Refrigeration

Baking immediately doesn’t give the bread time to absorb the custard. The result is uneven texture with dry spots and puddles of liquid. Always refrigerate overnight.

Overcrowding the Pan

Pressing too much bread into the pan prevents even soaking and baking. Leave some space between pieces. A 9×13 pan should hold one loaf of bread comfortably.

Cutting Bread Too Small

Tiny bread pieces turn mushy. Stick to 1-inch cubes. Larger pieces maintain structure better during soaking and baking.

Nutritional Information

Per serving (1/12 of recipe):

Calories: 320-380
Protein: 9-11 grams
Carbohydrates: 42-48 grams
Fat: 14-16 grams
Fiber: 2 grams
Sugar: 24-28 grams

These values vary based on bread type and toppings used. Using whole wheat bread and reducing sugar can lower calories and increase fiber.

Healthier Alternatives

Reduce Sugar

Cut the sugar by half or use natural sweeteners like honey or maple syrup. The vanilla and cinnamon provide plenty of flavor even with less sugar.

Use Milk Alternatives

Swap whole milk for almond milk, oat milk, or coconut milk. These work equally well in the custard mixture. For lower fat, use 2% or skim milk instead of cream.

Add Whole Grains

Use whole wheat bread or multigrain bread instead of white bread. This increases fiber and nutritional value.

Include More Fruit

Add extra berries, sliced peaches, or diced apples to increase vitamins and fiber. Fruit adds natural sweetness, allowing you to reduce added sugar.

Frequently Asked Questions

Can I make French toast casserole without eggs?

Traditional recipes need eggs for structure, but you can use substitutes. Mix 3 tablespoons of ground flaxseed with 8 tablespoons of water (let sit 5 minutes) to replace eggs. The texture will be slightly different but still tasty.

Do I have to use stale bread?

Stale or day-old bread works best because it absorbs liquid without falling apart. Fresh bread can work if you let the cut cubes dry out for a few hours on a baking sheet.

Can I bake it immediately instead of overnight?

You can bake after just 2 hours of soaking, but overnight produces better results. The longer soak creates a more uniform, custardy texture throughout.

What if my casserole is too eggy?

This happens when the ratio of eggs to bread is off. Use more bread or fewer eggs. The bread should be just moistened, not swimming in liquid.

Can I double the recipe?

Yes, use two 9×13 pans or one large roasting pan. Keep the same baking time but check doneness since larger pans may need 5-10 extra minutes.

Holiday and Special Occasion Ideas

French toast casserole works perfectly for special occasions:

Christmas Morning: Add cranberries and orange zest for festive flavor. Top with powdered sugar “snow.”
Easter Brunch: Use lemon zest in the custard and serve with fresh spring berries.
Mother’s Day: Make the cream cheese version and serve with champagne or mimosas.
Birthday Breakfasts: Let kids add their favorite mix-ins like chocolate chips or their preferred fruit.
Thanksgiving Morning: Prepare the pumpkin spice version to match the day’s flavors.

Budget-Friendly Tips

Making French toast casserole doesn’t have to be expensive:

Buy day-old bread from bakery discount racks
Use regular sandwich bread when challah is too pricey
Skip expensive nuts in the topping
Use frozen berries instead of fresh (they’re often cheaper)
Make your own vanilla extract for long-term savings
Buy eggs in bulk when on sale

A basic French toast casserole costs approximately $8-12 to make and serves 10-12 people. That’s less than $1 per serving for a filling breakfast.
