How to make-ahead eggnog french toast casserole
Make it for breakfast, dinner, the holidays – whenever you want to make it, here’s how!
Step 1: Start by cracking a dozen whole eggs into a large mixing bowl. Measure out 1-1/2 cups worth of good quality eggnog. Add your brown sugar and rum extract (or real rum) and whisk (affiliate link).
Step 2: Add the cubed loaf of cinnamon bread (cinnamon raisin is equally good) into the bowl. Be sure to use a rubber spatula or spoon to maneuver all the bread around in the egg mixture. We want every piece of the bread to be covered equally and have a chance at soaking up the eggnog flavors.
Step 1 Step 2
Step 3: You can either cook this immediately at 350F for 40 minutes in your cast iron skillet or you can let it soak. If you choose to let the bread mixture soak, you’ll want to cover it with plastic wrap and refrigerate for anywhere between 30 minutes to 24 hours. The more you let the liquid absorb, the shorter the cooking time could be. Be sure to check every 15 minutes with a tooth pick.
Step 4: After cooking, serve warm with any number of toppings. Due to the rich nature of the breakfast casserole, I suggest something acidic such as fresh raspberries to help cut through all the sugar and fat.

What can be substituted for Eggnog?
If you’re making this out of season and are craving some Eggnog but it’s not in stores, I would first suggest to try making your own. Otherwise, you can substitute vanilla chai tea for a similar flavor profile.
Does eggnog have alcohol?
Traditional eggnog can be served with or without alcohol. Traditionally you’ll see the drink spiked with rum, brandy, bourbon, or congac. While you can certainly add “the real thing” to this recipe since the alcohol will cook out, we went the virgin route and used rum extract instead. This lends the taste and bite of spiked eggnog without the actual need for liquor. To avoid the taste of rum altogether, use vanilla or almond extract in its place.
How to store and reheat leftover breakfast casserole
If you plan to enjoy this Eggnog French Toast Casserole within the next 72 hours, you can slip it out of the cast iron skillet and wrap with tinfoil. Seal it up completely. When ready to serve, slip it into a pre-heated 350F oven for 5-10 minutes. Fresh toppings will bring this casserole back to life in the most fluffy of ways.

I can’t wait to try this for my 10 year old granddaughter. Every year she waits anxiously for eggnog to start showing up at the stores. French toast casserole is a favorite for myself already and this recipe sounds like it will be a great new tradition for Christmas morning.
