French toast casserole is the perfect brunch recipe. It’s always a crowd-pleaser while simultaneously being an easy dish for the host to put together the day before. Overnight French toast casseroles are one of the best ways to enjoy effortless entertaining for busy holiday mornings or weekend brunches. Throw some fresh blueberries or frozen berries into the mix, and you’ve got yourself a dish that will have everyone coming back for seconds and asking for the recipe.

A French Toast Casserole Recipe Should be in Every Home Chef’s Repertoire

I’ve been known to say that I don’t like quick and easy meals. Since the process of cooking is actually enjoyable for me, I don’t always love throwing together a meal at the last minute. What I do love is a special breakfast that is easy to prep the day before. The kind that can be thrown into the oven the next morning, 45 minutes before guests arrive, and leaves the house smelling like I’ve been slaving away in the kitchen all morning.

French toast casserole is exactly that kind of dish. Like most overnight breakfast casseroles, a French toast bake is best prepared the night before. I tend to make it after the kids go to bed, letting it soak in a greased baking dish overnight. The next day, I simply top the casserole with cold butter, pop it in the oven until it turns golden brown, and enjoy.

Every home chef should have an easy blueberry French toast casserole recipe in their repertoire. It’s a great addition to brunch recipes, especially for Easter brunch, Mother’s Day brunch, holiday brunch, or even baby showers. If you’ve never tried it, now is the time to prepare this classic recipe!

How I Fell in Love with Blueberry French Toast Casserole

The flavors in this casserole are probably my all-time favorite combination when it comes to sweets. You can’t go wrong with fresh eggs, whole milk, cold butter, sugar, and fresh berries.

I’m not a huge sweets fan, but this dish is one I can devour in minutes. I’ve been making savory breakfast recipes my entire life—give me all the sausage, bacon, cheese, and hot sauce. While I prefer the carnivore version of this dish, I love switching to blueberries for Easter brunch and summer get-togethers. There is something about spring that makes me want to ditch the meat and eat all the blueberries.

This dish came together a few years ago when I entered my first (and only) recipe competition. It came as a huge surprise when I won! Winning finally gave me the confidence to develop recipes and call myself a food blogger.

 

What Kind of Bread to Use for Baked French Toast Casserole

My original recipe called for croissants.

This recipe, however, uses French bread. We often have leftover bread, and since I hate food waste, I wanted to use it up in my French toast casserole recipe. It’s crazy how changing the bread makes such a difference. This version is sturdier and holds up to the egg mixture much better. I cut the bread into 1-inch cubes and placed them in a buttered casserole dish. Using stale bread or crusty bread ensures the bread cubes soak up all the good things—milk, eggs, and vanilla—without turning mushy.

If you don’t have French bread on hand, sourdough bread and even old bread work well too. Different types of bread will yield slightly different textures, but they all make a great recipe. Just be sure to cut the bread into an even layer in the dish for the best results.

The Secret Ingredients for the Best French Toast Casserole Recipe

While I don’t mind changing the bread to make a slightly different spin on my blueberry French toast casserole, there are two ingredients that I’ll never change.

The first is the addition of almond extract. While it tastes perfectly fine with only vanilla, the almond adds a wow factor. The second ingredient that I can’t imagine changing is wild blueberries. It’s imperative that you use wild blueberries for their intense flavor and perfect texture.

Usually, I say that fresh is best, but in this case, I have to use frozen ones. Wild blueberries are only found up north, nowhere near my Florida home. You can find them at most grocery stores in the frozen aisle. If you prefer fresh blueberries, they work well too, but frozen berries hold up beautifully in this dish.

Serving and Topping Ideas

Once baked to golden brown perfection, this stuffed French toast casserole should cool slightly before serving. I love to dust the top of the casserole with powdered sugar for an extra touch of sweetness. Drizzle it with homemade blueberry sauce or classic blueberry syrup for a restaurant-quality dish.

This overnight soak method ensures every bite is filled with rich egg custard and bursts of blueberry goodness. Serve it warm from the oven for the ultimate holiday breakfast or weekend brunch treat!
