Easy French Toast Casserole

Overnight French Toast Casserole Recipe

I’ve blogged before about my love of breakfast foods. I could eat it any time of the day, and it’s fairly common to come over to the Merkley home on an evening and find us eating Belgian Waffles or Buttermilk Pancakes.

Breakfast recipes are just that great! I feel like we don’t get to eat them often enough in the mornings since we’re usually in a rush, but we occasionally get to enjoy them on the weekends and holidays. One holiday we always have breakfast is on Mother’s Day. And usually I’m not the one that has to bake it!! 😉

One of my favorite recipes to enjoy on this day is French Toast, and more specifically, today’s French Toast Bake. This breakfast bake is simple to make and is beyond delicious!!

This french toast casserole is made from pieces of sourdough bread, covered in an egg mixture, and topped with a buttery cinnamon sugar topping. Talk about DELICIOUS, right?!

Cut up sourdough bread for french toast bake

What is the best bread for french toast?

This baked french toast casserole recipe calls for sourdough bread, which is my personal favorite (and the only kind I’ve ever used). But if you don’t have sourdough on hand, there are a few other options you could try!

The main idea is that you want the bread to be sturdy enough that it will hold up after being combined with the egg mixture. Thinly sliced or squishy bread (think wonder bread) can fall apart while cooking after being soaked in the egg mixture. It’s also a bonus if it’s available in an uncut loaf, because then you can slice and cube it perfectly. Here are some other options:

  • Brioche
  • Challah
  • Pullman Loaf
  • French Bread

If you try any other breads, you’ll have to let me know how it turns out!

I think what makes it so good is the sourdough bread… oh, and the butter and the cinnamon and the sugar. It’s definitely one of our favorite dishes to make for holidays and weekend breakfasts!

How to Make French Toast Bake:

This recipe takes a few steps but is quite simple. To begin, cut your bread or loaf into cubes and place into a greased 9×13 pan.

In a bowl, mix together eggs, milk, heavy cream, sugar and vanilla. Pour evenly over the bread. Cover your pan with cling warp and refrigerate overnight.

Make streusel topping by mixing together flour, brown sugar, cinnamon and salt in a medium bowl. Cut in butter with this mixture until crumbly and place in a Ziploc bag. Refrigerate this mixture overnight as well.

When ready to bake, sprinkle crumbly mixture evenly over bread and bake.

Variations:

For a more savory casserole add: ham and cheese, chorizo, green chile, sausage or crumbled bacon.

For a sweet casserole add: thinly sliced apple, orange zest, sliced apricots, sliced pineapple, blueberries, chopped pecans

TIPS, TRICKS, and FAQ

Why is my french toast bake soggy? This casserole should be soft on the bottom and crisp on the top. If you find your casserole comes out too soggy try some of these tips:

  • Soak the bread in a separate bowl: If there’s too much egg in the pan it may be left a little soggy. One way around this is to store your bread mixture overnight in a bowl. In the morning transfer the bread to the baking dish leaving behind the extra liquid.
  • Choose the correct bread: choose a dense bread such as Brioche, Challah, Pullman Loaf, or French Bread.
  • Use a lipped cookie sheet instead of a 9×13 baking dish. You will have to adjust the bake time and watch carefully.
  • Not soaking the bread long enough: You want the egg mixture to seep deep into the bread for a soft custardy center. If the mixture doesn’t have time to soak into the bread it may end up creating a soggy mess.

Can you freeze it? Yes, you can choose to freeze it before or after baking. Wrap dish with plastic wrap then foil. It can keep for up to 2 months in the freezer. When you’re ready to eat thaw overnight in the fridge, remove all the wrapping and bake. If it been prebaked cook at 350 degree F for 20 minutes. If it has not been pre-baked, cook according to recipe directions.

Can french toast casserole be cooked in crock pot? Yes make according to recipe directions. Refrigerate for 6-10 hours in the ceramic crock pot. Place the ceramic pot into the heating base, cover and cook on low for 4 hours or high for 2 hours.

    1. The longer it sits, the bread soaks up the liquid on the bottom. I haven’t tried making it, then baking right away, but I am sure you can.

    1. I would just use the 24 ounce. If you feel like it’s too much bread or over-flowing, you can just leave some off.

    I’ve made a lot of different overnight casseroles and this one is our absolute favorite. So easy and so delicious! Thanks

    1. I haven’t substituted the heavy cream, so I haven’t tried the whole milk. That could work or I would google some suggestions.

    I made this tonight. cut the recipe in half and i used the $1 french bread loaf from walmart. was amazing and i’ll be making this again. thank you

      1. Do you cover this with foil while baking? I’ve made this several times and I use foil until the last 15 mins and take it off. I was just wondering what you do. Thank you so much for sharing this recipe, it’s become one of my families favorites!

  5. 5 stars
    This was delicious HOWEVER, It tasted more like a moist coffee cake then any French toast I’ve ever had. I would try this again just half the size or for a holiday brunch with friends and family once we are all able to be together again!

  6. 5 stars
    Made it today for a Thanksgiving brunch. Loved it. I will definitely make this again, especially when we have overnight company for the weekend. Thanks for sharing.

  7. 4 stars
    When I made this for my wife’s birthday it came out fantastic, and I should say I: Only soaked bread cubes 2 hours ahead, I buttered the bottom and sides of a lasagna pan for it, Packed the 1/2cup brown sugar, and Precut my 1 stock butter into 1/2” cubes. The end result after 55 mins was excellent, as it was crispy-ish on the bottom and sides, and custardy in The middle.
