Baked Blueberry French Toast

Baked French toast casserole reminds me of weekends away with family and friends in Tobago. Boy what i would do to have a weekend away in Tobago right about now! Each time we went this baked casserole was always on my list to make because not only is it super delicious, but it can also feed a crowd, its a crowd pleaser, and it can double as dessert too. It’s a total win every-time. Let’s talk about how simple this recipe is to make. This overnight blueberry French toast casserole is so much easier than making individual portions on the stove-top for 10-12 people. No dipping, flipping, or burning the fist couple before you nail the right amount of butter to grease the pan, or the temp. It’s a quick tear or chop, whisk and dump everything in a pan. The topping is a bit more complex but only slightly and it’s worth the extra effort cause it adds to the crispy caramelised edges of the french toast which no one can resist.

Baked Blueberry French Toast Ingredients

Blueberry French Toast Casserole Recipe Ingredients

  • BREAD: I recommend french bread, or sourdough bread, that is day-old bread. These types of bread work best because they hold up well with the soaking - challah bread, or Texas toast is fine too but it tends to be softer with and airy crumb and soaks up the custard easily and could potentially be a little too soggy if its not day old and dried out. Feel free to use gluten free bread if needed
  • MILK: Whole milk is best for this recipe, but 2% should work fine too.
  • EGGS: Helps bind everything together. You will need 8 eggs
  • CREAM: I like the richness heavy cream adds to the custard and casserole but feel free to replace it with more milk
  • BLUEBERRIES: Use Fresh blueberry or frozen. If using frozen berries there is no need to thaw simply add them in frozen. You can also use blackberries, raspberries or chopped or sliced strawberries or cranberries
  • SPICES: I added cinnamon to this easy french toast casserole to really amp up the flavours but feel free to add more warming spices like a pinch of nutmeg, ground ginger or ground cardamom is lovely with blueberries too
  • VANILLA: Pure vanilla extract delivers the best flavor.
  • SUGAR: The casserole is sweetened with granulated sugar, and brown sugar and the streusel topping gets some flavor from brown sugar.
  • BUTTER: I recommend using unsalted butter since the amount of salt in salted butters can vary between different brands.
  • FLOUR: Used in the streusel topping.
  • EXTRA ADD INS: If you want to amp up your French toast casserole scatter spoonfuls of softened cream cheese layered between the cubed bread for a a rich and indulgent French toast. Feel free to add some chopped nuts like pecans or walnuts to the crumble topping. Make a simple blueberry sauce to serve with the French toast for and extra berry full add on. Add a touch of lemon zest and lemon juice to the custard for a blueberry lemon spin, or even make it a little boozy by adding 1-2 tablespoons of some rum, triple sec or Cointreau.

French Toast Casserole Make Ahead, Storage & Freezing

Can I Make This Blueberry French Toast Casserole Ahead of Time? Yes that is the best part about this recipe that you can make it ahead up to 24 hours which makes it perfect for busy morning or holiday mornings. Here is how to do it:

  • MAKE AHEAD: Yes! I actually prefer to prepare the french toast breakfast casserole the night before and let it sit overnight so the bread can really soak up the custard. I even make the topping ahead and store in a zip-lock bag. Then in the morning, all you have to do is top it with the crumb topping and bake it.
  • STORAGE: Store leftover apple french toast casserole in an airtight container in the refrigerator for up to 3-5 days. Reheat individual servings in the microwave for 20-30 seconds if desired or in the oven or toaster oven.
  • FREEZING: The fully cooked and cooled casserole can be frozen, although it’s better when fresh. But if you have leftovers to freeze, wrap individual portions in plastic wrap and then a layer of foil. Defrost the individual slices in the refrigerator overnight then reheat until just warmed through in the microwave or oven. If you are freezing the whole casserole wrap in plastic wrap and foil and place cooled casserole in the freezer and store for up to 1 month - thaw in the fridge overnight and place in a preheated oven at 350°F for 10 to 15 minutes, or until warmed through and re-crisped on top.

It’s also fabulous because you can make both components, the french toast and the topping ahead and just stick it in the oven in the morning while everyone else is sleeping and then it’s ready when everyone starts waking up. Waking up to the smell of this baking is heavenly. Or it must be I should say -I wouldn’t know because its usually me making it. Hee hee - no bitterness there at all. I love making it and I love seeing people enjoy it. Johann loves it and he just loves to use up all my maple syrup all over it. We are talking puddles. He is not a cheap date folks, not when it comes to breakfast as all our friends can attest. He is a bottomless pit when it comes to breakfast and he only likes the good stuff when it comes to his syrup. No Aunt Jemima for him. Canadian maple all the way!

Baked Blueberry French Toast

It’s the perfect breakfast/brunch dish and I know you will love it. Writing this is seriously making me nostalgic for Tobago and for the people I love in Trinidad. In particular my one little nephew and set of cousins who thoroughly enjoyed this baked french toast. Maybe one day soon i will make it for them again! Until then I guess Johann and my dad can have at this - which they sure did after the last click of the camera and they did so happily!

Recipe Notes

  • For less custardy cover with foil at the 20 minute mark and continue to cook a few extra minutes until cooked to your desired texture
  • Instead of pouring the custard over the bread cubes in the casserole dish, feel free to mix or toss the bread cubes and the custard together in a bowl first to saturate all the cubes with the custard.
  • No one likes soggy bread! French toast casserole is one of those recipes that has a lot of variables. Maybe your eggs are a bit bigger, or your bread was too fresh etc. There’s an easy way to fix soggy French toast, though. Just increase your baking time until the casserole has reached your desired level of doneness. Cover loosely with foil to prevent top from burning or browning too quickly.
