Step‑by‑Step Instructions for Vegan French Toast Casserole
Step 1: Prepare Bread
Begin by cutting your stale loaf of bread into 1-inch cubes or thick slices, ensuring even pieces for uniform soaking. Stale bread absorbs the custard better, enhancing the texture of your Vegan French Toast Casserole. Set the pieces aside to prepare for the custard mixture.
Step 2: Make Custard
In a large mixing bowl, whisk together the dairy-free milk, brown sugar, cornstarch (or ground flax/chia), ground cinnamon, vanilla extract, and black salt until smooth. Allow the mixture to sit for about 5 minutes to thicken, creating a rich and creamy custard base that will envelop your bread perfectly.
Step 3: Assemble Casserole
Grease an 11 x 6 inch casserole dish and evenly distribute the cubed or sliced bread in the bottom. Pour the thickened custard mixture over the bread, ensuring all pieces are thoroughly coated. For the best flavor and texture, let it soak for at least 30 minutes or ideally overnight in the fridge, allowing the bread to absorb all that sweet custard goodness.
Step 4: Prepare Crumble
In a medium bowl, combine flour, chopped pecans, softened vegan butter, sugar, and a sprinkle of cinnamon. Use your fingers to rub the mixture together until it resembles coarse crumbs. This pecan crumble topping adds a delightful crunch and flavor contrast to the Vegan French Toast Casserole.
Step 5: Bake
Preheat your oven to 350°F (180°C). Once the oven is ready, sprinkle the prepared pecan crumble evenly over the casserole. Bake the dish for 30-40 minutes, or until the top is golden brown and the custard is set, creating a beautiful contrast of textures.
Step 6: Serve
After baking, let the casserole cool slightly before serving. Dust with powdered sugar for an added touch and serve warm alongside maple syrup or fresh fruit. Enjoy the warm and comforting flavors of your homemade Vegan French Toast Casserole, perfect for sharing with family and friends.

How to Store and Freeze Vegan French Toast Casserole

Vegan French Toast Casserole Recipe FAQs
What type of bread is best for the casserole?
Absolutely! Using stale bread is key to achieving that perfect texture. I recommend vegan brioche, French, Italian, or sourdough. The staleness helps the bread absorb the custard beautifully, making for a custardy interior instead of a soggy mess. If you’ve got fresh bread, consider leaving it out overnight to dry out a bit before using.
How should I store leftovers of the Vegan French Toast Casserole?
Very! Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, add a splash of dairy-free milk and pop it in the oven at 350°F (180°C) for about 10-15 minutes until warmed through. This helps maintain moisture and keeps the casserole delicious!
Can I freeze the Vegan French Toast Casserole?
Certainly! You can freeze the casserole before baking it. Wrap it tightly in foil and store it in a freezer-safe bag for up to 2 months. When you’re ready to enjoy it, just thaw it in the fridge overnight, then bake at 350°F (180°C) for 25-30 minutes until heated through. It’s a great way to meal prep!
What if my casserole comes out soggy?
If your casserole turns out soggy, it might be that the bread was too fresh or it didn’t soak long enough. To avoid this in the future, be sure to use stale bread and let it soak for at least 30 minutes or preferably overnight in the fridge. This will help the bread absorb the custard evenly without being overly soggy.
Is the pecan crumble necessary for the Vegan French Toast Casserole?
Not at all! The pecan crumble adds a delightful crunch, but it’s optional. If you prefer, feel free to skip it or swap it out for another topping, like granola or fresh fruit. You can even just dust the casserole with powdered sugar before serving for a simple yet delicious touch.
Are there any dietary considerations for the Vegan French Toast Casserole?
Absolutely! This casserole is egg-free and dairy-free, making it suitable for vegan diets. If you have nut allergies, you can substitute the pecans with seeds like sunflower seeds in the crumble. Always double-check your ingredients, especially for the dairy-free milk and vegan butter, to avoid any unwanted allergens.
