Ingredients You’ll Need

The beauty of this dish lies in its straightforward ingredients, each chosen carefully to build layers of flavor, fluffiness, and texture. From the tangy buttermilk that tenderizes and lifts the batter, to the burst of fresh blueberries and the sweet, crunchy crumble on top, every component plays a crucial role.

Flour: Use all-purpose flour, sifted or whisked to lighten the texture of the casserole for maximum fluffiness.
Buttermilk: Adds a tender, moist crumb and a slight tang that balances sweetness perfectly.
Fresh blueberries: The star of the dish, providing juiciness and vibrant bursts of flavor in every bite.
Brown sugar and cinnamon (crumb topping): Give a warm, caramelized crunch that contrasts beautifully with the soft pancake base.
Eggs and melted butter: Bind the ingredients together and enrich the overall flavor.
Lemon zest and vanilla extract: Add subtle brightness and aromatic depth, elevating this breakfast classic.

Step 1: Prepare Your Baking Dish

Preheat your oven to 350°F and generously grease a 9×13 baking dish. If you’d like a smaller size recipe you can half the recipe above and bake it in an 8×8 baking pan. This makes it perfect for fewer servings and slightly reduces the baking time.

Step 2: Mix the Crumb Topping

In a medium bowl, combine the flour, light brown sugar, granulated sugar, cinnamon, and salt. Pour in the melted butter and stir with a fork until fully incorporated. Pop this bowl into the refrigerator to keep cool while you whip up the pancake batter. This crumb topping will add a fantastic texture contrast.

Step 3: Whip Up the Pancake Batter

In a large bowl, whisk together the dry ingredients: flour, sugar, salt, baking powder, and baking soda. In a separate bowl, combine eggs, buttermilk, milk, melted butter, lemon zest, and vanilla extract. It’s okay if the butter clumps a little—it won’t affect the final texture. Pour the wet ingredients into the dry ones and gently fold with a rubber spatula just until combined; the batter should remain lumpy for a tender crumb.

Step 4: Assemble and Bake

Pour the batter into the prepared baking dish, spreading it out evenly. Scatter fresh blueberries over the top, then generously sprinkle the crumb topping across everything. Bake in the preheated oven for 35 to 45 minutes, until the casserole is puffed, golden, and cooked through in the center.

Side Dishes

Make Ahead and Storage

Storing Leftovers

This casserole keeps beautifully in the refrigerator for up to 3 days. Store it in an airtight container to prevent drying out, and enjoy its flavors happily reheated for a quick breakfast or snack.

Freezing

You can freeze individual slices wrapped tightly in plastic wrap and foil for up to 2 months. Just thaw overnight in the fridge and reheat in the oven or microwave to enjoy as if freshly baked.

Reheating

For best results, heat leftovers in the oven at 350°F until warmed through to keep the crumb topping crisp. If you’re in a hurry, microwave it in short bursts, but expect a softer topping. If you’d like a smaller size recipe you can half the recipe above and bake it in an 8×8 baking pan, this also makes reheating quicker and more convenient.

FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries work just fine; just scatter them directly on top of the batter after pouring it into the dish. No need to thaw — they’ll release lovely juices as it bakes.

Is there a substitute for buttermilk?

If you don’t have buttermilk on hand, mix 2 cups of milk with 2 tablespoons of lemon juice or vinegar, let it sit for 5 minutes, then use it as a perfect buttermilk replacement.

What can I do to make the topping more crunchy?

Add a handful of chopped nuts like pecans or walnuts to the crumb topping before baking. That little extra crunch brings delightful texture and flavor contrast.

Can I make this recipe dairy-free?

Sure! Swap the buttermilk and milk with unsweetened plant-based milks like almond or oat, and use vegan butter or coconut oil for the melted butter. The texture may be slightly different but still delicious.

How do I know when the casserole is done baking?

It should be puffed up and lightly golden brown on top. Insert a toothpick into the center—it should come out clean or with a few moist crumbs. If it’s still wet or batter-like, give it a few more minutes.
