Updated: Jun 29

Serves 8-10

For the French Toast

whole eggs



2 cups

heavy cream

1 cup


1 cup


1 tsp


a pinch

butter extract (leave out if you can’t find it)

1 tsp

vanilla extract

1 tsp

enriched bread. Example: potato bread, challah bread, brioche

1 loaf (more or less)

For the Shortbread Topping

softened butter

1 stick


½ cup


1 cup

dry oatmeal

1 cup

For the Salted Caramel Sauce


2 sticks

brown sugar

16 oz

heavy cream

1 cup

sliced bananas



1 tsp

Method of Prep:

This recipe is for a 5 quart casserole dish which is massive. If you have a 3 quart dish, I recommend halving the recipe.

In a medium sized mixing bowl, beat eggs until smooth. Next, mix in the milk, heavy cream, extracts, salt, and sugar. Next, spray the casserole dish with cooking spray. Place down 1 layer of bread and top with 1/3 of the egg custard mixture. Repeat until you have 3 layers of bread and egg mixture. Set aside.

Next, in a small mixing bowl, mix the dry ingredients for the shortbread topping. Add the butter and knead the mixture together with your hands. We’re just looking to incorporate the butter into the mixture. It will not be a bread dough. Next, place your hands into the bowl and grab two fists full of the shortbread mixture so that it clumps together. Gently break about the clumps so that you have some texture (some big chunks of shortbread, some little). Spread the shortbread mixture over the French toast casserole evenly. Cover with plastic wrap and refrigerate overnight.

Remove casserole from the refrigerator 2 hours before serving.

Bake casserole for approximately 45 minutes at 350 degrees covered with foil. Remove foil at 45 minutes and bake an additional 15 minutes to brown the top. You’ll know the casserole is done baking when the center reads 180 degrees on a thermometer.

For the sauce, heat a skillet over medium heat. Add the butter and melt (be sure not to brown the butter). Add the brown sugar and mix together while heating. The mixture will look like wet sand. Cook while stirring for 3-5 minutes. When the mixture is smooth, add heavy cream and stir vigorously until caramel forms. Add salt and stir in bananas. Serve warm with a slice of French toast casserole.
