How to Make Overnight Blueberry French Toast Casserole

Here is exactly how we make the dish: about 15 minutes of prep and roughly 75 minutes of cooking.

What you need: Oven, Baking Dish, Whisk, Mixing Bowl.

1. In a bowl, mix together the softened cream cheese, powdered sugar, 2 tablespoons of milk, and 1 teaspoon of vanilla bean paste until the mixture is smooth and creamy.
2. Gently fold in 1 cup of the blueberries to distribute them evenly throughout the mixture.
3. Layer the bottom of a 10 by 14 inch baking dish with bread cubes, creating an even base.
4. Spread the cream cheese mixture over this layer of bread cubes.
5. Once the mixture is evenly spread, top with the remaining bread cubes to form the second layer.
6. In a large bowl, whisk together 2 cups of milk, eggs, 2 teaspoons of vanilla bean paste, cinnamon, and nutmeg until fully combined.
7. Pour this mixture over the layered bread in the baking dish, ensuring all the bread is soaked.
8. Sprinkle 1 cup of blueberries evenly on top.
9. Cover the dish tightly with aluminum foil and refrigerate for 8 hours or overnight.
10. Remove the dish from the refrigerator 30 to 60 minutes before baking.
11. Preheat your oven to 375 F to prepare for baking the dish.
12. Bake the dish in the preheated oven for 45 minutes with the foil on.
13. After 45 minutes, remove the foil and continue baking until the center is set and the top is lightly browned, about 30 more minutes.
14. Once baked, remove the dish from the oven and let it cool slightly before serving.

That is the whole method. Nothing here needs special technique, just a little attention at the right moments.

• Use a dish close to the size called for. Too large and it dries out, too small and it bubbles over.
• Read the steps once before you start. Knowing what is coming makes the whole thing calmer.
• Have everything measured and within reach before the heat goes on. Have everything measured and within reach before the heat goes on.

Variations and Add Ins

Overnight blueberry french toast casserole takes changes well, so treat the recipe above as a starting point rather than a set of rules. These are the swaps we come back to most often.

• Change the shape. Anything with ridges or curves holds this sauce well.
• Add protein. Chicken, beef or shrimp turn it into a full dinner.
• Sneak in vegetables. Spinach, peas or broccoli stir in at the end with no fuss.
• Make it lighter. Half and half in place of cream keeps it silky with less richness.
• Change the herbs. Fresh parsley, basil or dill at the end each send it somewhere slightly different for no extra effort.
• Make it a bigger meal. Serve it over rice or with warm bread and it stretches to feed another person or two.

Change one thing at a time rather than three. That way you find out what you actually like in the recipe instead of guessing at the end.

How to Store and Reheat Overnight Blueberry French Toast Casserole

Leftovers keep in an airtight container in the refrigerator for up to three days. Pasta drinks up sauce as it sits, so add a splash of broth or cream when you reheat it and stir until it loosens up again.

If you are cooking ahead on purpose, prep the components and keep them separate until you are ready. It takes a few minutes off a busy evening and this one holds its texture far better that way.
