There are a number of ways to make french toast casserole, the most popular probably being the “overnight” version.

While that method allows the filling to soak into the breading, I have found that the mix and bake method is quite delicious as well.

It actually leaves the bread soft and fluffy, which is a little different than french toast was originally meant to be, but very delightful.

Sourdough Bread French Toast

With a brand new stand-up mixer in the house calling my name, I decided to show it some love and use it to make homemade sourdough bread.

Using a stand-up mixer or kitchen aid is absolutely necessary in order to make bread. Without it, the bread will end up flat and dense.

I know this now because that’s how my bread would turn out before the days of the mixer.

Making homemade bread is not necessary, and I do list some of my favorite/popular loaves of bread to use for french toast casserole below.

Cast Iron French Toast

Sourdough French Toast Casserole Recipe

Start out by chopping up a loaf of sourdough or preferred choice of bread into decent size chunks. Add to a large, 12″ cast iron skillet.

In a small mixing bowl, combine eggs, milk, honey, cinnamon, and salt. Mix well and drizzle evenly over the top of the bread.

At this point, you can either cover the dish and place it in the fridge overnight to let the mixture soak into the bread or continue on.

Either way, the following steps will be the same. First, dot the top of the dish with butter, then sprinkle with cinnamon and sugar.

Bake at 375°F for 35 minutes or until done. Oven times greatly vary, so adjust cooking times accordingly. Let rest 5-10 minutes before serving.

This french toast casserole is best enjoyed warm with a glass of OJ. However, if you do find yourself with leftovers, It can be kept in the refrigerator for up to 5 days and reheated in the oven.

How to Spruce up French Toast

The whole point of this recipe blog is to share recipes that are simple, quick, and for the most part, use ingredients generally found in most kitchens.

So, with that being said, check out these delicious add-ins for a one-of-a-kind french toast casserole.

Bacon

Add crumbled-up bacon over the top of the dish just before baking. A unique twist on the traditional french toast

Orange Zest

Zest an orange and sprinkle the top when there are about 5 minutes left on baking. This is not for everybody-but I recommend trying it at least on one half of the dish.

Cinnamon Raisin

Use cinnamon swirl or cinnamon raisin bread in replace of sourdough. Add ¼ cup of raisins to the egg mixture. Absolutely delicious!

Nuts

Add your favorite nuts for a little added crunch: pecans, walnuts, hazelnuts, macadamia, etc. Mix the nuts in when adding the bread.

What Kind of Bread to Use?

Of course, this recipe calls for sourdough, but use whatever kind you prefer, gluten-free, egg-free, etc. and let me know how it turned out in the comments.

  • French Bread
  • Sourdough
  • Italian
  • Brioche bread (I make a chocolate chip French toast this way)
  • Thomas Cinnamon Swirl bread, it gives the whole dish a different “vibe.”

  2. I made this with an almond flour bread and it worked well! Still did honey but used some brown sugar to make up part of th sweetener. You could tell it was a less fluffy and nutty tasting bread but everything tasted the same from your recipe’s stand point! The bread didn’t loose it’s shape either

    This is the bread recipe I used. https://healthyrecipesblogs.com/gluten-free-bread/

  3. In your directions you never mention when to put the eggs in until step 6 “or until eggs are cooked through”
