Baked Brioche French Toast Casserole: Ingredients You’ll Need

Alright, let’s get down to the good stuff: the ingredients! You’ll need a few simple things, and I promise, it’s totally worth it. The quality of your ingredients makes a huge difference, so try to use the best you can find. Here’s what you’ll need, and trust me, don’t skimp on the fresh stuff!

  • 1 loaf of brioche bread, cubed (about 8-10 cups)
  • 6 large eggs
  • 1 1/2 cups milk (whole milk is best, but 2% works in a pinch!)
  • 1/2 cup heavy cream (this is where the magic is!)
  • 1 teaspoon vanilla extract (pure vanilla, if you’ve got it!)
  • 1 teaspoon ground cinnamon
  • 1/4 cup packed light brown sugar
  • Butter, for greasing the baking dish (unsalted is what I use)

Easy peasy, right?

Ingredient Notes and Possible Substitutions

Okay, let’s talk about these ingredients a little more. I’ve been making this french toast for ages, and I’ve learned a few tricks along the way. First off, the star of the show: the brioche! It’s got that rich, buttery flavor that makes this casserole so special. If you can’t find brioche, challah bread is a great substitute. Just make sure it’s a good, sturdy loaf so it can handle all that delicious egg mixture.

For the dairy, whole milk and heavy cream are my go-to, because hello, deliciousness! But you can totally use 2% milk if that’s what you have. I haven’t tried it, but I bet almond milk would work too. As for the sweetness, the brown sugar on top is key, but feel free to adjust the amount to your liking. Taste the batter before pouring it into the dish, and add a little more sugar if you want it sweeter. You can also add a sprinkle of powdered sugar on top when serving. Yum!

How to Make Baked Brioche French Toast Casserole

Okay, now for the fun part: making this amazing baked brioche french toast casserole! Don’t worry, it’s super simple, I promise. Just follow these steps, and you’ll be golden. And remember, baking is all about a little love and patience. Let’s get started!

First things first, preheat your oven to 350°F (175°C). While that’s heating up, grab a 9×13 inch baking dish and grease it generously with butter. I like to use a pastry brush to make sure every nook and cranny is covered. You don’t want your french toast sticking, trust me!

One of the best tips I can give you is to use slightly stale brioche. It soaks up the egg mixture better and doesn’t get all mushy. If your bread is super fresh, you can leave the cubed brioche out on the counter for a few hours to dry out a bit. Now let’s get to the good stuff!

Preparing the Egg Mixture

In a large bowl, whisk together your eggs, milk, heavy cream, vanilla extract, and cinnamon. Whisk it all until it’s well combined and the mixture is nice and smooth. You want the cinnamon to be evenly distributed, so give it a good mix. Don’t worry about being perfect here; it’s all about getting those flavors mixed up!

The consistency should be like a thin custard. Taste it! You can add a pinch more cinnamon or a splash more vanilla if you want. It’s your french toast, so make it how you like it!

Assembling the French Toast Casserole

Now, for the soaking part! Add the cubed brioche bread to the egg mixture. Gently press down on the bread cubes to make sure they’re all getting soaked up. Let it sit for about 5-10 minutes, stirring gently halfway through. You want the bread to soak up most of the liquid, but not become totally soggy.

Next, pour the soaked bread mixture into your prepared baking dish. Make sure the bread is evenly distributed. Now, sprinkle that delicious brown sugar evenly over the top. This is what’s going to caramelize and make the top so wonderfully crunchy! It’s the best part, in my opinion!

Baking and Serving Your Baked Brioche French Toast Casserole

Pop that baking dish into the preheated oven and bake for 35-40 minutes, or until the top is golden brown and the french toast is set. You can test for doneness by inserting a knife into the center. If it comes out clean, it’s ready! If it’s still a bit wet, give it a few more minutes.

Once it’s out of the oven, let it cool for about 10 minutes before serving. This helps it set up a bit more. Serve it warm, and get ready for everyone to rave! You can top it with all sorts of things: fresh berries, maple syrup, whipped cream, a dusting of powdered sugar… the possibilities are endless! Enjoy!

Tips for the Best Baked Brioche French Toast Casserole

Okay, friends, listen up! I’ve made this french toast a million times, and I’ve learned a few tricks to make it absolutely perfect every single time. First off, and I can’t stress this enough, use slightly stale brioche! It soaks up that delicious egg mixture like a dream, and it won’t get all mushy on you. If your bread is super fresh, just leave it out on the counter for a few hours to dry out a bit. Trust me, it makes a difference!

Next, don’t over-soak the bread. You want it to be soaked, yes, but not swimming in the egg mixture. And finally, keep an eye on that baking time. Ovens vary, so start checking around 35 minutes. You want that top to be golden brown and the inside custardy. You got this!

Variations: Spice Up Your French Toast

Okay, now for the fun part: making this french toast your own! Don’t be afraid to get creative and play around with the flavors. You can add a pinch of nutmeg or cardamom to the egg mixture for a warmer spice profile. For toppings, try fresh berries, sliced bananas, or even a drizzle of chocolate sauce (I won’t judge!).

If you’re feeling extra fancy, add a layer of cream cheese filling in the middle before baking, or sprinkle some chopped nuts on top for a little crunch. The sky’s the limit, so get in there and experiment! You might even invent your own family favorite!

So, you’ve got this amazing baked brioche french toast casserole, and now you need to complete the brunch spread! Don’t worry, I’ve got you covered. This casserole goes great with pretty much anything, but here are a few of my favorites. You’ll definitely want a pot of hot coffee, maybe some crispy bacon or sausage, and a side of fresh fruit or creamy yogurt to balance out the sweetness.

Freshly squeezed orange juice is also a must! Honestly, you can’t go wrong. Just think of your favorite brunch foods and pile ’em on. It’s all good, I promise!

Storage and Reheating Instructions

So, you’ve got leftovers? Amazing! This baked brioche french toast casserole is just as good the next day, if not better. Let it cool completely, and then store any leftovers in an airtight container in the fridge. It should last for about 2-3 days.

To reheat, you can pop a slice in the microwave for a minute or two, or you can reheat it in the oven at 350°F (175°C) until warmed through. Oven reheating is my favorite because it helps crisp up the top again! Just make sure it’s heated all the way through for food safety. Enjoy!

What kind of bread is best for french toast?

Brioche is, hands down, my favorite. It’s got that rich, buttery flavor and the perfect texture for soaking up that delicious egg mixture. But, if you can’t find brioche, don’t worry!

The key to a non-soggy french toast casserole is a few things. First, use slightly stale bread. This helps it soak up the egg mixture without getting overly mushy. Next, don’t over-soak the bread.
