Gluten Free French Toast Casserole

Hosting weekend brunch is always a favorite in our house — it’s relaxed and casual, people aren’t in a rush to get home on a weeknight or to get home to a babysitter on a weekend evening. Bring your boyfriend! Bring your baby! Bring your favorite booze! It’s an entertainer’s dream.

Recently I made this gluten-free french toast casserole for a Sunday brunch. It was easy (and just as sweet) as pie and I was more than happy to accommodate a friend’s dietary needs. Which reminds me: while etiquette specifies it’s up to a guest to share her dietary restrictions, I think if you’re entertaining, it’s always nice to ask your guests if they have any restrictions. Especially when you may be unfamiliar with someone, it’s nice to check to be sure there aren’t any uncomfortable moments around the table.  Serving shrimp burgers to your cousin’s new kosher boyfriend? #awkward.

Anyway, back to the recipe. Here’s what you’ll need.

2 gluten-free baguettes, sliced in 1″ pieces [regular bread would work fine here too!]
8 eggs, beaten
2 cups unsweetened vanilla almond milk
1 cup brown sugar
1/2 stick butter, melted then cooled
1 tbsp cinnamon
2 tbsp vanilla
confectioner’s sugar for topping


  1. Beat eggs, almond milk, sugar, butter, cinnamon and vanilla until very well incorporated
  2. Submerge bread in egg mixture until well coated
  3. Arrange sliced bread in a circular design around a 12″ cast iron skillet, slightly overlapping each piece
  4. Pour remaining egg mixture over the bread
  5. Place skillet in refrigerator at least 4 hours, or overnight
  6. Remove casserole from refrigerator and preheat oven to 350 degrees
  7. Bake 45 minutes to 1 hour, or until the egg mixture is fully cooked and the casserole is golden brown
  8. Remove from oven and let sit about 10 minutes, dust with confectioner’s sugar and serve as is or with maple syrup

We ate this decadent dish with fresh berries, and no maple syrup — it just didn’t need it! Most people didn’t even notice the bread was gluten-free.  And if you and your guests aren’t gluten-free, certainly just whip this up with your usual baguette.  The best part is definitely the crispy edges caramelized with crunchy sugar. OMG yum.  This is obviously not a light dish, but everyone needs to live a little, right?! Indulge! Enjoy! Sit back and dig in…

Please let me know how you like this recipe if you make it at home! I’d love to hear from you.  Hope you enjoy!
