Blueberry french toast casserole ingredients and substitutions

Bread: I used soft buns/rolls. You can use either white, seeded or whole wheat/wholemeal buns (or a bit of each). Alternatively use brioche buns. See below for more details.
Eggs.
Milk: use any.
Blueberries: use fresh or frozen.
Sugar: I used demerara for extra crunch but you can use any.
Butter: creates a delicious crispy finish.

What blueberries to use

You can use either fresh or frozen blueberries. I chose the latter as they tend to keep their shape in baking better than fresh.

Best bread for french toast bake

If I am making French toast the traditional way in a frying pan I tend to use bread slices. However, I find that french toast in casserole form works best when using soft buns (which I also used in banana and chocolate french toast bakes as well as french toast muffins). They soak up the egg mixture (quite generous in this recipe) extremely well as well as quickly and come out of the oven fluffy and moist.

TIP: You can use brioche buns instead but bear in mind they will add on extra calories.

Step-by-step recipe instructions

1. Prepare bread: Break the buns into chunks and place in your casserole dish.

2. Make egg mixture: Combine the eggs with the milk and whisk until smooth.

3. Combine with bread: Pour the mixture over the bread and stir. Set aside for 5 minutes, then give another stir.

4. Add blueberries: Scatter the blueberries over the top tucking in between the bread without pressing down, sprinkle the sugar and drizzle with the melted butter. Bake for 30-40 minutes until lightly browned.

Serving suggestions

This healthy blueberry french toast casserole is delicious on its own but you can also enjoy it with a drizzle of maple syrup or honey, fresh fruit or fruit compote.

Can french toast casserole with blueberries be made ahead

Yes, it can! You can prepare the bread mixture and add the blueberries the night before but drizzle over the butter just before baking. Also, if using frozen blueberries I recommend adding them the following day (they will defrost overnight and may become soggy).

Optional extras

This blueberry french toast bake is delicious as it is but you can add other ingredients for a different flavour twist or texture. These can include:

cinnamon
lemon zest
sunflower seeds or flaxseed
almond flakes
wheat germ for added fibre

Top tips

Use either frozen or fresh blueberries.
If using white buns you can sprinkle a bit of wheat germ over the top for extra fibre (this is optional).
Cooking times may vary depending on the size and depth of your casserole dish. If you use a smaller dish the casserole mixture will be more compact and you may have to bake it a little longer. It is ready if the middle is no longer wobbly.
Best served straight from the oven.
Leftover blueberry french toast casserole can be refrigerated, covered for up to 2 days. Reheat individual portions in the microwave.
Freezing: You can freeze this casserole uncooked for up to 3 months (wrap it tightly with foil). Defrost in the fridge overnight.
