Ingredients You’ll Need

Picking the right ingredients makes all the difference with this Baked Blueberry French Toast Casserole Recipe. I like to use a sturdy sourdough loaf and fresh or frozen blueberries for the best texture and flavor. Let me share some tips on these essentials so your casserole turns out perfect.

• Sourdough loaf: Day-old bread is ideal because it soaks up the custard without falling apart, giving a sturdy yet soft texture.
• Eggs: Eggs create that rich custard base; I use large eggs for just the right balance.
• Milk of choice: Whole milk is my go-to, but you can switch to almond or oat milk for a lighter or dairy-free option.
• Maple syrup: Adds natural sweetness—feel free to adjust the amount depending on how sweet you like it.
• Cinnamon: A warm spice that pairs beautifully with blueberries and enhances the overall flavor.
• Vanilla extract: Adds depth and richness without overpowering the other ingredients.
• Salt: Just a pinch to balance the sweetness and bring everything together.
• Blueberries: Fresh are best in season, but frozen works fine too—just don’t thaw them beforehand to avoid excess liquid.
• Cinnamon sugar (optional): Sprinkling this on top before baking gives a lovely crunchy, lightly sweet finish.

Variations

I love how adaptable this Baked Blueberry French Toast Casserole Recipe is. Over time, I’ve tried switching out fruits and spices to suit the season or my mood, and it all turns out delicious. Don’t be afraid to make it your own with these easy swaps.

• Fruit Variation: Tried it with raspberries or sliced peaches when blueberries weren’t in season — still a hit at the table!
• Dairy-Free Option: Use coconut or almond milk, and it’s just as creamy thanks to the eggs.
• Nutty Twist: Sprinkle chopped walnuts or pecans on top before baking for extra crunch and flavor.
• Chocolate Lover’s: Add mini chocolate chips between the layers for a sweet surprise in every bite.

How to Make Baked Blueberry French Toast Casserole Recipe

Step 1: Whisk up your custard base

Start by whisking 6 large eggs in a large bowl until smooth. Then add 2 cups of milk, between ¼ to ⅓ cup maple syrup depending on your sweetness preference, 1½ teaspoons cinnamon, 1 teaspoon vanilla extract, and just a pinch (about ⅛ teaspoon) of salt. Whisk it all together really well. This custard mixture is what soaks into the bread and blueberries, giving you that rich, tender texture we’re aiming for.

Step 2: Layer the bread and blueberries

Grab a 9×13 inch baking pan and spray it with cooking spray to prevent sticking. Then spread half of your 1-inch sourdough cubes evenly across the bottom. Sprinkle half of the blueberries over the bread. Repeat the layers one more time with the remaining bread cubes and blueberries. The layering is key here — it ensures every bite has a good balance of fluffy bread and juicy berries.

Step 3: Pour, cover, and chill

Pour the custard mixture slowly over the layered bread and blueberries, making sure to saturate every corner. Cover the whole pan tightly with aluminum foil and pop it in the fridge. I like to let mine sit for at least 30 minutes, but honestly, the longer the better — overnight works wonderfully if you want to prep ahead and wake up to breakfast ready to bake.

Step 4: Bake to golden perfection

When you’re ready, preheat the oven to 350°F (175°C). Remove the foil from your casserole and, if you’re using cinnamon sugar, sprinkle a generous layer on top for a sweet crunch. Bake uncovered for 45 to 50 minutes or until the top is golden and slightly toasted. You’ll know it’s done when the custard is set and a knife inserted in the center comes out clean. Let it cool for a few minutes before serving.

How to Serve Baked Blueberry French Toast Casserole Recipe

Garnishes

I love topping this casserole with a light dusting of powdered sugar for a pretty touch and extra sweetness. Maple syrup drizzled on top is a classic, but you can also add a few extra fresh blueberries or a dollop of whipped cream for an indulgent finish. It’s these little details that make breakfast feel extra special.

Side Dishes

This casserole pairs wonderfully with crispy bacon or sausage links if you want some savory to balance the sweet. A simple green fruit salad or fresh orange slices brighten the plate and add freshness. I often serve it with a hot cup of coffee or vanilla-flavored tea for a breakfast that feels like a treat.

Creative Ways to Present

For holidays or brunches, I like to bake this casserole in individual ramekins for elegant single servings. Another fun idea is layering it in clear glass dishes so the beautiful bread and blueberry layers are visible—a feast for the eyes before you even dig in. Adding edible flowers or fresh mint leaves right before serving adds a lovely pop of color that guests always appreciate.

Make Ahead and Storage

Storing Leftovers

Leftovers store beautifully in an airtight container in the fridge for up to 3 days. I recommend cutting into portions before storing to make reheating easier. The texture stays creamy and flavorful, so you won’t feel like you’re eating stale breakfast.

Freezing

If you want to freeze leftovers, wrap individual portions tightly in plastic wrap and place in a freezer-safe bag. I’ve found the casserole keeps well frozen for up to a month. When you’re ready, thaw overnight in the fridge before reheating for the best texture.

Reheating

Reheat your leftovers in a 350°F oven for about 15 minutes or until warmed through. This method helps preserve the crispy top and creamy inside better than microwaving, which can make it soggy. If you’re short on time, microwaving works fine—just sprinkle a little extra cinnamon sugar on top afterward for crunch.
