The Chemistry of French Toast

The chemistry of this casserole revolves around the egg and milk mixture. When baked, the proteins in the eggs coagulate, setting the custard around the bread and sausage. The bread soaks up this mixture overnight, ensuring every bite is moist and flavorful. The cheese melts and adds a rich, gooey texture, while the dry mustard adds a subtle tangy complexity to the dish.

Sweet or Savory?

For breakfast time, are you team sweet or savory? I have ALWAYS been team sweet since I was a little girl, but as I get older I am finding that I prefer a balance of both if possible. When I am having a holiday brunch or breakfast party, I love to make some Cinnamon Rolls and this Savory French toast. Then everyone is happy, team sweet, team savory & team both.

How long should you chill a French toast casserole?

Ideally, chill it overnight, or for at least 8 hours, to allow the bread to fully absorb the egg mixture. Chilling also allows the flavors to meld and makes your casserole more flavorful.

Can this casserole be made with different meats?

Yes, you can customize this casserole to what you like. This recipe is actually my Grandma Eleanors recipe, she always did sausage, so now I always do. I love having recipes tied to her, each one brings back memories of cherished family time. Another good option would be bacon. Just make sure to cook it fully first, you wouldn’t want to add raw meats to the casserole.

What type of bread do you use?

The beauty of this recipe is that you can use any soft bread you like. Every different bread type will bring a hint of different flavors, so choose your favorite bread. For me, I like to use what is on hand, and that is normally a store bought loaf of sandwich bread. If you wanted to go fancy, you could use a yummy bakery bread, like challah.
