Savory French Toast Casserole Tips and Tricks
Melt Your Butter
The first thing you will want to do after pre-heating the oven is melt your butter. You can melt it over the stove, in the oven, or if you’re lazy like me, just chuck it in the microwave.
Add your stick of butter to a microwave-safe bowl (I just use my glass measuring cup) and microwave on high in 30-second intervals. Stir in between, and just keep heating until the butter completely liquefies. Simple as that!
Green tip: Look for organic and palm oil-free butter if you can. Buying organic means you are supporting farms that do not use damaging pesticides and fertilizers, and palm oil production is a huge driver behind deforestation.
Outside of the butter, you’ll need just a few more ingredients, most of which you will probably already have in your pantry or fridge.
Here’s everything you’ll need:
Whisk It Up
While your butter is melting, you can get started on your egg wash. Dice your scallions and add them to a medium-sixed mixing bowl with all 6 eggs, and the milk, salt, pepper, and paprika.
Whisk it well so it’s nice and smooth.
Cube The Bread
The next step is cubing the bread. You can use any bread for this recipe. You’ll need a whole loaf of any bread you choose. If your loaf is whole, slice it into pieces about 1-inch thick.
If your bread is already sliced, it’s as easy as slicing it into 4 roughly equal parts vertically, then rotating it and slicing it into roughly thirds as pictured below.
The Order of Events
Grab a 9×13-inch casserole dish. First, add the melted butter and place cubed bread pieces on top. Next, you’ll pour the egg wash mixture over the bread, trying to evenly distribute it as much as you can.
Next comes the cheese. Cover all the bread evenly to make a top layer of cheese. It’ll get bubbly and brown in the oven, creating a layer of cheese that will lock the moisture into the bread (you’ll never even know it was stale!).
I use sharp cheddar when I make this and it’s out of this world! But if you have another cheese preference—go for it! I recommend using a low moisture cheese rather than something with a lot of liquid, like mozzarella or brie, for best results.
Green tip: Bread is one of the most wasted food products in the U.S. because of our tendency to throw it out as soon as it’s stale. Reduce your contribution to food waste by re-vamping your stale bread with this Savory French Toast Casserole!
Should You Have Leftovers
This Savory French Toast Casserole is meant to feed 6-8, although I did warn you of it’s addictive nature. But if you do have incredible willpower and happen to have leftovers—I got you!
Cover and keep in the refrigerator for 5-7 days or the freezer for up to a month. Reheating it is a breeze.
From the fridge, reheat a single serving on a frying pan for about 5 minutes on each side, until thoroughly heated through. You can also reheat it in the toaster or the oven at 375°F for 10 minutes from the refrigerator or 15 minutes from frozen.
The microwave will work in a pinch, but does tend to make it a little soggy.
