Ingredients for sourdough french toast casserole

Creating the best sourdough French toast casserole begins with choosing the best bread that works harmoniously together. The star of the show is, of course, the sourdough bread. For this recipe, opt for a robust, crusty loaf with a chewy interior. Day-old sourdough works wonderfully because it soaks up the custard better than freshly baked bread, ensuring that every bite of your sourdough French toast casserole recipe is saturated with flavor.

Here’s what you’ll need:

  • Sourdough Bread: A sturdy loaf or a couple of smaller ones are ideal. Using day-old or slightly stale bread helps the egg mixture adhere better, preventing the casserole from becoming mushy.
  • Eggs: These create the rich custard base that transforms the bread into French toast. A generous number of eggs will ensure a firm yet tender set.
  • Milk and/or Cream: Use a combination of milk and cream to get the perfect consistency for your homemade sourdough bread. The cream adds richness, while the milk helps the custard spread evenly in your French toast bake.
  • Maple Syrup and Brown Sugar: These sweeteners balance the tang of the sourdough. Maple syrup adds a deep, natural sweetness, and brown sugar brings a hint of caramel flavor.
  • Cinnamon: A generous pinch—or more—is essential to infuse the casserole with warm, spicy notes, enhancing the flavor of the sourdough French toast casserole recipe.
  • Vanilla Extract: Just a splash for a touch of aromatic sweetness in your breakfast recipe.
  • Salt: To enhance the flavors of the custard and the bread.
  • Optional Add-Ins: Consider adding a handful of berries, chopped nuts, or even a drizzle of extra maple syrup on top of your French toast bake before serving.

Each ingredient plays a crucial role in building layers of flavor in this delicious breakfast recipe. The sourdough provides a robust, tangy backdrop; the custard brings a silky texture; and the spices and sugars deliver a sweet and aromatic finish. By combining these elements, you create a dish that is both comforting and exciting—a perfect marriage of sweet and savory with a hint of rustic charm.

How To Make Your Sourdough French Toast Casserole

Hands assembling sourdough french toast casserole by pouring custard over bread cubes.

Step 1: Preparation and Assembling the Casserole

Begin by preheating your oven to 375°F (190°C). While the oven warms up, cut your sourdough bread into cubes or tear it into bite-sized pieces. Arrange the bread pieces evenly in a greased casserole dish. This dish should be large enough to hold all the bread pieces in a single layer so that every piece can soak in the delicious custard.

In a large mixing bowl, whisk together the eggs, milk, cream, maple syrup, brown sugar, cinnamon, vanilla extract, and a pinch of salt. The goal is to achieve a smooth, well-blended custard that will seep into the bread, ensuring every cube is fully coated. Pour the egg mixture evenly over the bread cubes, making sure that all the pieces are thoroughly saturated. Let the mixture sit for about 15 to 20 minutes; this allows the bread to absorb the custard, ensuring a moist, flavorful outcome.

Step 2: Rest and Overnight Assembly

For the best results, cover the casserole and refrigerate it overnight. This resting period not only intensifies the flavors but also gives the bread plenty of time to soak up the egg mixture. The next day, remove the casserole from the fridge and let it sit at room temperature for 15 minutes before baking. This slight warming helps the custard spread evenly during the bake.

Step 3: Baking to Perfection

Place the casserole in the preheated oven and bake for approximately 40 to 45 minutes, or until the top is a beautiful golden brown and the custard is set for your delicious breakfast. During the last 10 minutes of baking, you can sprinkle a little extra brown sugar and cinnamon on top if you desire a crunchier, caramelized finish. Keep a close eye on the casserole during these final minutes to avoid over-baking.

When the casserole is done, remove it from the oven and let it cool for a few minutes before serving. The cooling time allows the custard to firm up a bit more, making it easier to slice and serve.

Pro Tips and Variations

Mastering the Casserole

  • Choose the Right Bread: Consider using leftover sourdough or sandwich bread for a unique twist. The success of this dish largely depends on the quality of the sourdough bread. A loaf that has a thick, crusty exterior and a soft, chewy interior is ideal. If you have extra sourdough that’s slightly stale, use it—it soaks up the custard better than fresh bread.
  • Overnight Soak: Allow the mixture to rest in the fridge overnight for a richer flavor in your sourdough French toast casserole recipe. Don’t skip the overnight step. Allowing the bread to absorb the egg mixture for several hours intensifies the flavors and ensures a more consistent texture throughout the casserole.
  • Even Distribution: Make sure that every piece of bread is evenly coated with the custard. Stir the mixture over the bread gently after pouring to help distribute it evenly throughout the French toast bake.
  • Baking Time: Every oven is different, so check your casserole a few minutes before the end of the recommended baking time. The top should be crisp and golden, and the center should have a slight wobble that sets as it cools.

Creative Variations

  • Fruit Add-Ins: For a fruity twist, add a layer of fresh or frozen berries between layers of bread. Blueberries, raspberries, or sliced strawberries complement the tang of the sourdough wonderfully.
  • Nutty Crunch: Sprinkle chopped pecans, walnuts, or almonds on top before baking. The nuts add a delightful crunch and a nutty flavor that pairs well with the sweetness of the custard.
  • Extra Spice: Experiment with spices—nutmeg, cardamom, or even a pinch of ginger can add an unexpected twist that enhances the overall flavor profile.
  • Savory Version: If you prefer a less sweet breakfast, consider reducing the amount of brown sugar and maple syrup in your homemade sourdough bread recipe. Add a dash of black pepper or even a sprinkle of grated cheese for a savory version that still retains the classic texture and comfort of a French toast casserole.

By incorporating these pro tips and variations, you can personalize this breakfast recipe to suit your taste preferences and dietary needs. Whether you choose to stick with the classic version or venture into new flavor territories, the versatility of this dish means there’s always room for experimentation.

FAQs

Why is my French toast casserole soggy?

A soggy French toast casserole can result from several factors. One common reason is using bread that is too fresh or not letting it sit long enough in the egg mixture. Day-old or slightly stale sourdough works best because it absorbs the custard without breaking down completely. Over-soaking the bread or using too much liquid in the custard can also cause sogginess. Adjusting these variables and ensuring proper baking time can help achieve that perfect balance between moist custard and a crispy top.

Does baked sourdough bread get more sour over time?

Baked sourdough bread can develop a more pronounced tang as it cools, but it does not necessarily become more sour over time. The flavor is primarily determined by the fermentation process and the sourdough starter used during preparation. Once baked, the flavor profile stabilizes, although storing it in certain conditions might slightly alter its taste. For best results, enjoy the casserole soon after baking or store it properly to maintain its flavor integrity.

What is one common mistake when preparing French toast?

One common mistake when preparing French toast is not allowing the bread to adequately absorb the egg mixture. This can lead to a dry, underwhelming texture where the custard fails to infuse every bite of the sourdough French toast casserole recipe. It is essential to cut or tear the bread into pieces that expose enough surface area, and then let it sit for a sufficient period—preferably overnight in the refrigerator—so that the flavors meld thoroughly. This simple step can dramatically improve the overall outcome of the dish.

How far ahead can I make French toast casserole?

French toast casserole is a make-ahead dish that benefits from being assembled the night before. Ideally, you can prepare it up to 24 hours in advance. This allows the bread to absorb the custard completely, resulting in a richer, more flavorful French toast bake recipe. If you need to prepare it even further ahead, you can store the assembled casserole in the fridge for an extra day; however, for the best texture and flavor, it is recommended to bake it within 24 hours of assembly.

How can you tell when French toast is done?

Determining doneness for French toast casserole involves checking both the appearance and texture. The top should be a beautifully golden brown with a slightly crispy finish, while the custard in the center should be set but still have a slight jiggle when you gently shake the dish. A toothpick or knife inserted in the center should come out mostly clean, indicating that the custard has cooked through without becoming overly dry.

How do you keep a casserole moist?

To maintain moisture in a French toast casserole, ensure that the loaf of bread is adequately soaked in the egg mixture without being oversaturated. Using day-old sourdough helps achieve this balance in your delicious breakfast. Additionally, covering the casserole with foil during part of the baking process can trap steam and prevent the dish from drying out. Allowing the casserole to rest for a few minutes after baking also helps the custard settle, ensuring that every bite remains delectably moist.


By following these detailed steps and tips, you’re well on your way to creating a sourdough French toast casserole that stands out as a truly memorable breakfast dish. Enjoy the process of making it as much as you’ll enjoy eating it, and don’t be afraid to experiment with the pro tips and variations to suit your unique taste. Happy cooking! Make this recipe for a delicious breakfast.
