The Best Bread For French Toast Casserole

While it can still be hard to find a hearty, crusty gluten-free bread that's also vegan, if you must use a standard sandwich bread loaf, the number one thing to remember is it must be left out overnight to stale or be lightly toasted. But, the best gluten-free bread option for this specific French toast bake is sourdough! Not just any sourdough, but a loaf of crusty cinnamon raisin gluten-free sourdough! Cozy cinnamon, lightly sweetened, perfectly vegan, and allergy-free. The bread in this casserole is truly the star of the show! (Don't like raisins or want a plain version? Try this plain gluten-free sourdough loaf instead!)

Ingredients You'll Need

ingredients for gluten-free french toast casserole

  • Gluten-Free Sourdough Bread: The tang and sweetness of this cinnamon raisin gluten-free bread is so delicious, it's literally what makes this recipe THE BEST!
  • Brown Sugar + Granulated Sugar Sweeteners: The molassesy flavor of brown sugar with some granulated sugar, give this French toast bake that comforting sweetness and crisp top. You can use Swerve brown sugar sweetener and granulated sweetener to cut the extra sugar!
  • Flax Eggs: Part of the eggless custard to hold this vegan French toast casserole together is two prepared flax eggs.
  • Starch or Chickpea Flour: Arrowroot or cornstarch work great, but I recommend using chickpea flour instead! This addition gives the eggless custard a perfect thickness, extra protein, and slightly nutty, eggy flavor.
  • Nutritional Yeast: The real eggless eggy flavor comes from nutritional yeast! An essential ingredient for any vegan French toast recipe. It adds the perfect umami, slightly cheesy flavor (and more extra protein)!
  • Non-Dairy Milk: I like to use unsweetened light canned coconut milk. Canned coconut milk is thicker than refrigerated non-dairy milk and adds a beautiful richness without the need for butter and oils.
  • Cinnamon + Vanilla + Extra Raisins: Cinnamon and vanilla extract are essential for optimal flavor. Adding in some extra pops of chewy raisins is delicious, but totally optional!

The Cinnamon Streusel Topping

You don't have to include this additional cinnamon streusel topping, but, why not? You only need a few extra ingredients!

  • Brown Sugar Sweetener: Light or dark will work, again you can use a sugar-free brown sugar sweetener.
  • Gluten-Free Flour: All-purpose or whole grain gluten-free flour with more flavor like brown rice or sorghum!
  • Vegan Butter: Two tablespoons of your favorite vegan butter to make this cinnamon topping rich and delicious.
  • Cinnamon: The more cinnamon the better!

How To Make A Vegan French Toast Casserole With Gluten-Free Bread

prepping gluten-free bread for french toast casserole

Making The Eggless Custard:

  1. Add the dairy-free milk, chickpea flour (or starch), nutritional yeast, sweeteners, cinnamon, and vanilla together in a bowl.
  2. Mix it together and allow it to thicken while you prep the bread.

Prepping The Gluten-Free Bread:

  1. Prep the bread by slicing the gluten-free loaf and cutting it into 1-inch chunks. You can also go for a rustic look and tear the bread into bite-sized irregular pieces!
  2. Add the cubed bread to the bowl of thickened custard and toss so the pieces are all fully coated. You can toss in the extra raisins during this step as well.

Making The Streusel Topping:

  1. In a small bowl, combine the gluten-free flour, cold vegan butter, brown sugar, and cinnamon together with a fork. Use the fork to mash the mixture until crumbly.
  2. Add more gluten-free flour if the mixture isn't crumbly enough.

Preparing The Casserole:

  1. Ideally, you'll allow the bread to soak in the fridge overnight or for at least a few hours.
  2. Once the bread has soaked up all the eggless custard, pour it into a casserole dish and sprinkle on the crumble topping.

Baking The Casserole:

  1. Preheat the oven to 375˚F and bake the French toast for 30-35 minutes, until the top is crisp and golden.
  2. Remove the casserole from the oven, and let it cool for a few minutes. Sprinkle it with some powdered sugar and extra cinnamon, if desired, before serving!

How To Serve

Scoop out a big serving of your French toast casserole and top it with some classic maple syrup and powdered sugar or try some of these fun ideas!

  • Fresh fruit like blueberries, banana slices, strawberries, or raspberries
  • Vegan honey, brown rice syrup, molasses, sugar-free syrups
  • More raisins or other dried fruits like currents, cranberries, or blueberries
  • A dollop of coconut whipped cream or marshmallow fluff
  • Give it a drizzle of drippy nut or seed butter
  • Add some chocolate chips
  • Give it a salty crunch with some vegan coconut bacon

Other Tips & Tricks

  • Enhance your vegan French toast casserole with other add-ins like chocolate chips, fresh berries, nuts, or seeds. Add them directly into the custard with the cubed bread before baking.
  •  Soaking the casserole overnight is best because it allows the bread to absorb all the liquid which makes the inside of the baked casserole custardy and decadent!
  • If you want an even more eggy taste to your eggless casserole you can add a pinch of black salt!
  • If you're using a soft white gluten-free sandwich bread, make sure it is very stale or nicely toasted. If not, your casserole will be mushy and gross.

How To Store Leftovers

You can store leftover baked French toast casserole covered in the fridge for about 5 days. You can reheat leftovers in the oven at 350°F for 10 to 15 minutes or give individual servings a zap in the microwave for a minute or two.

How To Freeze French Toast Casserole

Baked French toast casserole can be frozen by wrapping individual servings in plastic wrap and foil or by tightly covering the entire casserole with plastic wrap and foil for up to 6 months. Allow the frozen casserole to thaw overnight in the fridge and reheat in the oven at 350°F for 10 to 15 minutes or heat the individual servings in the microwave for a minute or two.

  • Category: Breakfast
  • Method: Bake
  • Cuisine: American

Ingredients

Scale
  • 1 Loaf of Gluten-Free Sourdough Bread (Cinnamon Raisin or Plain)
  • ¼ Cup Light Brown Sugar Sweetener (or preferred brown sugar)
  • ¼ Cup Granulated Sweetener (or preferred granulated sugar)
  • 2 Flax Eggs (2 TB Milled Flax Seed + 6 TB Water)
  • ¼ Cup Unsweetened Light Canned Coconut Milk (or other non-dairy milk)

Instructions

  1. In a large bowl, combine the dairy-free milk, chickpea flour (or starch), nutritional yeast, sweeteners, cinnamon, and vanilla. Mix well to combine so there are no lumps.
  2. Cube your gluten-free sourdough bread loaf into one-inch pieces. You can even rip the pieces with your hands for a more rustic irregular casserole.
  3. Add the gluten-free bread pieces into the thick eggless custard along with the raisins or other add-ins you choose to use.
  4. Mix the bread so all the pieces are fully coated in the custard and allow it to absorb the liquid for at least 2-4 hours, overnight is best. (You can bake it right away, but this is not recommended)
  5. Prep the streusel crumb topping by adding the sweetener, flour, cinnamon, and cold butter to a small bowl and use a fork to mash together the crumb until clumpy. Place it in the fridge until you are ready to assemble the casserole.
  6. Preheat the oven to 375˚F and lightly grease an 8x8 casserole dish with butter.
  7. Dump the soaking bread mixture evenly into the greased casserole dish. Use your fingers to sprinkle on the additional streusel crumb to the top of the casserole.
  8. Bake the French toast casserole in the oven for 30-35 minutes, until the top is crisp and golden brown.
  9. Remove the casserole from the oven and allow it to cool for about 10-15 minutes before sprinkling the top with powdered sugar if desired, and serving.

Notes

  • The streusel crumb topping is optional and you can leave it out if desired.
  • Store leftovers covered in the fridge for about 5 days. You can reheat leftovers in the oven at 350°F for 10 to 15 minutes or heat individual servings in the microwave for a minute or two.
  • Freeze leftovers by wrapping individual servings in plastic wrap and foil or by tightly covering the entire casserole with plastic wrap and foil for up to 6 months. Allow the frozen casserole to thaw overnight in the fridge and reheat in the oven at 350°F for 10 to 15 minutes or heat the individual servings in the microwave for a minute or two.

    This sounds delicious! I'm still adopting to a forced partially vegan diet after contracting alpha-gal syndrome from a tick bite. I haven't found a vegan French toast recipe yet, and bonus that this is a casserole dish! Can't wait to try it!

Celiac Disease is NOT a food allergy 🚫🍞 So Celiac Disease is NOT a food allergy 🚫🍞

So many people still confuse the two, but it’s an autoimmune disease, not an allergy. That means gluten doesn’t cause an immediate allergic reaction resulting in hives or swelling…it causes your immune system to attack your small intestine longterm. 

This distinction matters because:
👉 There’s no medication or quick fix
👉 The only treatment is a strict, lifelong gluten-free diet
👉 Mislabeling it as an “allergy” is scientifically incorrect. There is no such thing as a gluten allergy.

Swipe through to learn why the distinction is inportant and why accurate education and awareness is paramount. Let’s set the record straight and not mislabel our disease when speaking about it. 💛
