As a child I grew up on casserole meals, which resulted in adult-me having a strong aversion to anything that’s baked and served in a 9×13 pan. Too much of a good thing truly is too much.

Now as a busy mom, I can definitely see the appeal of these one-pot/one-pan style meals. In fact, I’m trying hard to embrace these meals since they’re generally easy to make and result in a bunch of leftovers — both of which I could definitely use more of in life.

Lately, on the weekends, my family has been enjoying Baked French Toast Casserole. This hearty breakfast is the embodiment of everything there is to love about a casserole meal:  

  • One pan
  • Easy to make
  • Prep ahead friendly
  • Family friendly
  • Feeds a crowd (or just a very hungry family)

This particular casserole does require some advance planning since it needs to be made at least 12 hours before baking. During this rest time, the egg and cream mixture is absorbed by the bread cubes. I’ve been preparing the casserole on Saturday night before we go to bed.

I wanted to share this recipe before Easter (next week), just in case you’re planning a spring bunch. This casserole would be a great addition to any brunch spread, or to a special family breakfast. (This einkorn coffee cake would be another great brunch meal.) The casserole feeds about 6 people, although I think this number could be increased if other foods (such as a sweet and tart fruit salad or bacon) are served with the casserole.

Oh, and one last note: Don’t skip the crumble topping! While the crumble may not appear as much when you sprinkle it on top of the soaked bread cubes, just wait until you pull the warm casserole from the oven. You’re in for such a treat! While the crumble bakes, it crisps up, resulting in a sweet, cinnamon-flavored streusel topping that makes this casserole irresistible.

Ingredients

French Toast:

  • 14-16 ounce sourdough loaf (day-old/stale) about 9 packed cups of cubed bread
  • 8 eggs
  • 1 1/3 cups whole milk
  • 1 cup heavy cream
  • 1 TB pure vanilla extract
  • 1/3 cup pure maple syrup
  • 1 tsp cinnamon
  • 1/2 tsp nutmeg

Streusel Topping:

  • 1/2 cup all-purpose einkorn flour *
  • 1/3 packed cup light brown sugar
  • 3 TB unsalted butter cubed
  • 1 TB cinnamon
  • 1/2 tsp nutmeg
  • 1/4 tsp salt

Special Equipment

Instructions

  1. Prepare the casserole the night before you want to bake and serve it.

  2. Butter a 9x13 baking dish very well.

  3. Tear or cut the stale bread into rough, 2-inch chunks and line the pan with the bread. 

  4. Crack the eggs into a large mixing bowl. Whisk very well. Add the remaining french toast ingredients to the bowl, and whisk to combine.

  5. Pour the mixture over the bread. If needed, press down gently to make sure all the bread is in contact with the egg mixture.

  6. Cover and refrigerate overnight.

  7. Prepare the topping by combining all the ingredients in a small bowl with a pastry cutter or your fingers, until it resembles coarse crumbs. Cover and store in the fridge.

  8. The next morning, remove the casserole from the fridge while the oven preheats to 350F. Tip the pan to one side. If you notice a lot of liquid, drain the excess liquid from the casserole (this varies depending on the bread). 

  9. Sprinkle the streusel topping evenly over the casserole.

  10. Once the oven is hot, bake the casserole for 50-65 minutes (depending on the pan used--dark ceramic pans usually require more baking time than clear glass pans), until set. The casserole is done when the center is set. 

  11. Let the casserole cool for a few minutes (about 5-10 minutes), then slice and serve with maple syrup (if desired). 

Recipe Notes

*Spelt, all-purpose, or wheat flour may be used in place of the einkorn flour. Oat flour may also work.
