Ingredients

Labelled ingredients for blueberry french toast casserole.
  • French Bread – 1 loaf
  • Whole Milk – is the best for a creamy custard in this recipe.
  • Heavy Cream
  • Brown Sugar – I used a light brown sugar
  • Eggs
  • Vanilla Extract – I like to use pure vanilla extract for the best flavor, you could also substitute with artificial if that is what you have on hand
  • Cinnamon – ground cinnamon
  • Salt
  • Butter
  • Blueberries – you can use fresh or frozen blueberries, I like to use fresh blueberries if in season and available
  • Maple Syrup – pure maple syrup is best for serving

Substitutions

In place of heavy cream you can use whole milk but the casserole will not be as rich.

You can use less brown sugar if you do not like it as sweet.

What type of bread can I use?

You can use sourdough bread, brioche, or challah. Make sure the bread is very dry before baking. If the bread is too moist it will result in a soggy casserole!!

Variations

Make a streusel topping for this French toast casserole

You can make a streusel crumble topping by combining 7 Tablespoons of cold butter, 1/3 cup light brown sugar, 1/3 cup of all purpose flour and 1/2 teaspoon of ground cinnamon.

With clean hands, fork or pastry blender, combine ingredients until you have a crumbly consistency. Sprinkle the streusel on top of the casserole before baking.

Sandra’s Pro Tips

  • If the top starts to get too brown, tent the top of the baking dish with aluminum foil
  • When you store any leftovers they can become soggy, reheating it in the oven will help it to not be soggy
  • Serve with fresh fruit salad, maple syrup, whipped cream or easy homemade blueberry syrup. A sprinkled of powedered sugar adds sweetness and looks pretty on a plate as well.
