Blueberry Tips
Selecting the best blueberries is crucial for your casserole. Look for plump, firm berries that have a deep blue hue. Avoid any that appear shriveled or mushy. If you’re fortunate to have a local farmer’s market, that could be a great place to find fresh, in-season blueberries with incredible flavor. Always wash them gently before using, and if they are slightly overripe, they will still work beautifully when baked.
Options for Substitutions
- You can swap whole grain bread with gluten-free bread if preferred.
- Frozen blueberries work just as well, especially when fresh ones are out of season.
- Substitute low-fat milk with almond milk or oat milk for a dairy-free option.
- Instead of sugar substitute, regular sugar or honey can be used for added sweetness.
- Egg replacements, such as flaxseed meal mixed with water, are great for a vegan option.
- Feel free to add nuts or seeds for extra crunch and nutrition.
Watch Out for These Mistakes
A common pitfall when preparing this casserole is not greasing the dish thoroughly. If you skip this step, you may find your casserole sticking to the bottom, making it hard to serve. Make sure to use enough grease on the dish.
Another mistake is rushing the refrigeration process. Allowing the mixture to soak overnight is essential because it helps the bread absorb the liquid, leading to a creamy texture. If you don’t refrigerate it long enough, your casserole might end up dry.
Lastly, keep an eye on the baking time! Every oven varies slightly, so start checking around the 40-minute mark. You want it to be puffed and just set, but not overcooked or burnt.

What to Serve With Baked Blueberry Stuffed French Toast Casserole?
Pair your casserole with crispy turkey bacon or breakfast sausage for a hearty breakfast. A light fruit salad can also complement the sweetness of the dish while adding freshness. For something cozy, a hot cup of herbal tea or freshly brewed coffee is a perfect match.
Storage Instructions
Store: This casserole can be stored in the refrigerator for up to 3-4 days in an airtight container.
Freeze: You can freeze leftovers for about 2-3 months. Just ensure it is well-covered to prevent freezer burn.
Reheat: For stovetop reheating, place slices in a skillet over low heat until warmed through. In a microwave, heat individual portions on low power until hot.

- 6 eggs
- 2 cups low-fat milk
- 1/4 cup sugar substitute
- 1 tsp vanilla
- 1 tsp cinnamon

Step-by-Step Instructions
Step 1: Grease the Baking Dish
Start by greasing a 9×13-inch dish thoroughly to prevent sticking. Use a cooking spray or butter to coat the bottom and sides evenly.
Step 2: Layer the Bread and Blueberries
Next, layer the cubed whole grain bread in the greased dish. Scatter the fresh blueberries throughout the bread cubes to ensure every bite is fruity and delicious.
Step 3: Prepare the Custard Mixture
In a separate bowl, whisk together the eggs, low-fat milk, sugar substitute, vanilla, and cinnamon until well combined. This mixture will create the custard that soaks into the bread.
Step 4: Combine and Refrigerate
Pour the egg mixture evenly over the bread cubes and blueberries. Press down gently with a spatula to ensure all the bread absorbs the custard. Cover the dish with plastic wrap and refrigerate overnight.
Step 5: Bake the Casserole
Preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it sit out while the oven is heating. Bake for 45-50 minutes until puffed up and set.
Step 6: Cool and Serve
Once it’s baked, let the casserole cool for about 10 minutes before serving. This will help it set slightly, making cutting easier. Enjoy your breakfast!
