Ingredients You’ll Need
Simple ingredients, big payoff:
For the casserole:
- 1 loaf day-old bread (cubed) — slightly stale = perfect texture
- 1 ½ cups fresh or frozen blueberries
- 2 cups plant milk (almond, oat, soy—your pick)
- 1/3 cup maple syrup
- 2 tbsp sugar (optional, if you like it sweeter)
- 2 tbsp ground flaxseed + 5 tbsp water (flax “eggs”)
- 1 tsp vanilla extract
- 1 tsp cinnamon
- 1/4 tsp salt
Optional toppings:
- Powdered sugar
- Extra maple syrup
- Vegan butter
- Crumble topping (oats + sugar + vegan butter = chef’s kiss)

Step-by-Step Instructions
- Prep your flax eggs.
Mix flaxseed with water and let it sit for 5–10 minutes. It’ll thicken up like magic (science, but make it edible). - Cube the bread.
Cut into bite-sized chunks. Slightly dry bread works best—it soaks up all that custardy goodness. - Mix the custard.
In a bowl, whisk plant milk, maple syrup, flax eggs, vanilla, cinnamon, and salt. Make sure it’s well combined—no lazy mixing. - Assemble the casserole.
Add bread cubes and blueberries to a greased baking dish. Pour the custard over everything and gently press down so all the bread gets soaked. - Let it sit (if you have patience).
Rest for 10–15 minutes—or overnight in the fridge if you’re planning ahead. - Bake it.
Bake at 180°C (350°F) for 35–45 minutes until golden on top and set in the middle. - Serve it up.
Top with powdered sugar and maple syrup. Try not to eat it straight from the dish… or do. No judgment.

Common Mistakes to Avoid
Let’s keep this brunch-worthy:
- Using fresh soft bread.
Too soft = mushy mess. Slightly stale bread is your best friend. - Not soaking the bread enough.
Dry spots = disappointment. Press it down and let it absorb. - Skipping the flax eggs.
They help bind everything. Without them, it’s chaos. - Overbaking it.
You want soft and custardy—not dry and crumbly. - Too many blueberries.
Yes, it’s possible. Balance is key.
Alternatives & Substitutions
Because we improvise around here:
- Different berries:
Strawberries, raspberries, or mixed berries all work beautifully. - No flaxseed?
Use chia seeds instead—same idea, same magic. - Gluten-free bread:
Works perfectly—just pick a sturdy one. - Lower sugar option:
Reduce maple syrup or skip added sugar entirely. - Add nuts:
Walnuts or pecans for crunch = elite move.
