Instructions

PREPARING THE FRENCH TOAST CASSEROLE

  1. Grease 9x13 inch baking pan with butter (I use a paper towel and schmear it around). This recipe can also be split into two 9x9 or 8x8 pans.
  2. Tear the bread into chunks or if you prefer cut into cubes and distribute evenly into the prepared pan. Day old or stale bread is preferred as it will soak up the ingredients well. If you like, while you are prepping things, tear the bread apart and leave it on a baking sheet while you prepare the topping and egg mixture.
  3. In a large bowl, crack your eggs one at a time and whisk after each addition. Add in milk, cream, granulated sugar, brown sugar, vanilla and sea salt. Whisk well until thick, creamy and eggs are blended in well. If desired, add a littel extra cinnamon and nutmeg to the egg mixture.
  4. Pour mixture evenly over torn bread into pan(s), cover pan tightly and store in fridge overnight (or until needed) -- you can bake it right away, although it's best if let sit overnight.

MAKING CINNAMON CRUNCH CRUMB TOPPING

  1. In a medium-large mixing bowl add ½ cup flour, ½ cup packed brown sugar, 1 teaspoon cinnamon, 1/4 tsp nutmeg and generous pinch of salt. Mix together with a fork. Add butter and mix together with fork, hands, or mixer until it's combined. Freeze for 15 minutes before adding to casserole or store overnight in baggie in fridge.
  2. Once it's combined, toss it in a ziplock baggie and store in the fridge with the french toast mixture and let it chill overnight.

BAKING THE CINNAMON CRUNCH FRENCH TOAST

  1. While this may be baked right away, I recommened allowing it to sit for at least a couple of hours in the fridge. When ready, preheat the oven to 350°F (175° C) and remove your casserole from the frigde to come to room temperature before baking.
  2. Crumble the Cinnamon crunch evenly over the top of the casserole now.
  3. Bake for 45 minutes for a softer, more bread pudding like consistency or 1 hour plus 5-10 minutes for a firmer, crisper texture. I split the different in my family, I like it softer, they like it firmer, so I usually bake for about 55 minutes.
  4. Serve, if desired with warm maple syrup, soft butter and sliced berries.

Notes

  • Storage Tips
  • Cover the leftover French toast casserole tightly with foil or transfer to an airtight container and refrigerate for up to 3-4 days. For longer storage, slice portions and freeze them in airtight bags or containers for up to 2 months, I'd wrap them in plastic first.
  • Reheat: When ready to enjoy, simply reheat in the oven at 350°F until warmed through or pop a slice in the microwave for a quick, cozy breakfast!
  • This recipe slightly adapted from the Pioneer Woman.
  • Any leftover (white) bread works well; my favorites are Brioche, Challah (egg bread) and French Bread, but you can use Sourdough, along with other white breads as well. 
  • If you split the casserole into two pans, I suggest at least making 1 1/2 servings of the crumb topping, maybe even double it. Can you really have too much crumb topping? I think not!
  • You may freeze your french toast casserole before or after baking! To cook, remove casserole from freezer day before you want to serve. Allow the casserole and crumb topping to thaw in refrigerator overnight, then bake as directed.
  • Serve alongside my Mango Berry Salad or Yogurt Parfait for a fresh breakfast or brunch!
