Let’s Start Cooking: Step-by-Step Instructions

Step 1: Choose Your Bread Wisely

The foundation of any French toast casserole is the bread, and it can make or break your dish. For this recipe, I recommend a hearty whole-grain loaf. I

t’s sturdy enough to soak up the egg mixture without getting soggy, and it adds a nutty flavor that complements the blueberries.

Pro Tip: If your bread is fresh, let it sit out overnight to dry slightly. Slightly stale bread absorbs the custard better.

Step 2: Prepare Your Casserole Dish

Start by greasing a large casserole dish with a light spray of coconut oil or a dab of butter. This ensures your casserole doesn’t stick and gives you those beautifully crisp edges that everyone loves.

Step 3: Make the Custard Base

In a mixing bowl, whisk together:

6 large eggs 🥚
2 cups of unsweetened almond milk 🥛
1/4 cup of maple syrup 🍁
1 teaspoon of vanilla extract 🌼
1 teaspoon of cinnamon and a pinch of nutmeg 🌿

This mixture is the heart of your casserole, adding moisture and flavor. The cinnamon and nutmeg give it that cozy, warm vibe that screams comfort food.

Step 4: Assemble the Layers

Cut your bread into 1-inch cubes and spread half of them evenly across the bottom of the dish.
Sprinkle a generous handful of fresh or frozen blueberries on top. These little gems will release their juices as they bake, creating pockets of tart sweetness.
Add the remaining bread cubes, followed by another layer of blueberries.

Step 5: Pour and Soak

down gently, ensuring every piece of bread is soaked. If you have time, let the casserole sit for 15–20 minutes (or refrigerate overnight). This step is key for allowing the flavors to meld and the bread to absorb the custard fully.

Pro Tip: Want an extra protein boost? Add a scoop of unflavored whey protein to the custard mixture before pouring.

Step 6: Bake to Perfection

Preheat your oven to 350°F (175°C). Cover the dish with foil and bake for 25 minutes. Then, remove the foil and bake for an additional 20–25 minutes, or until the top is golden brown and the custard is set. You’ll know it’s ready when a knife inserted into the center comes out clean.

Creative Flavor Additions

If you’re like me and love to experiment, here are some fun ways to make this casserole uniquely yours:

Nut Lovers: Sprinkle chopped pecans or slivered almonds over the top for a delightful crunch.
Coconut Twist: Mix shredded coconut into the custard or sprinkle it on top before baking.
Citrus Kick: Add a teaspoon of orange zest to the custard for a bright, tangy twist.
Chocolate Indulgence: Scatter dark chocolate chips over the top for a decadent treat.

Storage and Reheating Tips

Fridge: Store leftovers in an airtight container for up to 5 days.
Freezer: Slice into individual portions, wrap tightly, and freeze for up to 2 months. Reheat in the oven at 350°F until warmed through.
Reheating: For best results, reheat in the oven to maintain the texture. If you’re in a hurry, the microwave works too—just cover the casserole with a damp paper towel to prevent it from drying out.

Pairing Suggestions

To complete your meal, here are a few ideas for what to serve alongside this dish:

Greek Yogurt Parfait: Layer Greek yogurt with granola and fresh fruit for added protein and crunch.
Smoothie: A vibrant green smoothie with spinach, banana, and almond milk pairs beautifully with the casserole.
Side of Turkey Bacon: For a savory contrast, crispy turkey bacon is a fantastic choice.
