If you’re looking for an eggless french toast casserole you can make ahead for brunch or holidays, this recipe checks every box. Sweet, creamy, and full of bright citrus flavor, this Key Lime Cheesecake French Toast Casserole instantly makes brunch feel like a moment.
It actually came together in the sweetest way. My daughter loves my mom’s key lime cheesecake and my eggless french toast, and one day she asked if we could combine the two. I wasn’t sure what to expect, but it ended up being one of those recipes we instantly fell in love with. Now it’s something we make for guests, holidays, or anytime we want to elevate brunch without a lot of extra effort. It’s soft, rich, and layered with little pockets of cheesecake in every bite.
If you’ve tried my Eggs Benedict Casserole or Blueberry Cheesecake French Toast Casserole, this fits right in with those. It’s simple, a little unexpected, and always the first thing to disappear.
Why This Key Lime Cheesecake French Toast Casserole Works
You won’t miss the eggs here at all, promise! Instead, cornstarch gives the casserole structure so it sets beautifully, while baking powder keeps everything soft and fluffy.
The combination of heavy cream, sweetened condensed milk, and cream cheese creates that rich, creamy texture that feels like cheesecake tucked into every bite.
It’s one of those recipes that looks impressive but is actually really simple to make, which is exactly what I want when I’m hosting or feeding my family.
Why You’ll Love This Key Lime Cheesecake French Toast Casserole
This is one of those recipes that checks every box.
It’s rich and creamy without feeling heavy, and the bright citrus flavor keeps it from being overly sweet. The texture is soft and fluffy with little pockets of cheesecake throughout, which is truly the best part.
I love that you can prep it the night before and just bake it in the morning. It makes hosting feel so much easier.
And honestly, it’s just beautiful on the table. Add a little whipped cream and lime zest and it feels like something you’d order at a brunch spot.
Ingredient Spotlight
Key lime juice
This is what gives the casserole that signature fresh citrus flavor. It’s slightly sweeter and softer than regular lime juice, which is why it works so well in desserts.
Brioche bread
Soft, buttery, and perfect for soaking everything up. It gives you that rich, bakery style texture.
Sweetened condensed milk
Adds sweetness and helps create that smooth, creamy base without needing eggs.
Cream cheese
This is what creates those little cheesecake pockets throughout the casserole.
FAQs
Can I make this the night before?
Yes, and I actually recommend it. Just assemble everything, cover it, and refrigerate overnight. In the morning, let it sit out while the oven preheats, then bake as directed.
What Kind of Bread Works Best?
Brioche is my favorite because it’s soft and buttery, but challah or Hawaiian bread work really well too.
If I Use Regular Limes, Do I Need to Adjust the Recipe?
Yes, regular (Persian) limes are more acidic and less sweet than key limes. If you’re using them as a substitute, you may want to slightly reduce the lime juice (by 1–2 tablespoons) or add a little extra sweetened condensed milk to balance the tartness. The result will still be delicious, just a bit bolder and tangier than the classic soft citrus flavor you get with key limes.
Is This Really Eggless?
It sure is! This casserole skips the eggs and instead uses cornstarch to create that classic custard texture and baking powder to help it rise. The result is light, creamy, and totally satisfying without the eggs.
Can I Freeze the Leftovers or Make It Ahead and Freeze?
Yes, absolutely! Once the casserole has cooled completely, you can either wrap individual slices for a quick heat and go breakfast or cover the entire dish tightly to freeze as a whole. It freezes beautifully for up to 1 month. To reheat, simply warm in the oven or microwave until heated through. It’s also a great make ahead option if you want to prep brunch a week (or more) in advance. Just thaw overnight in the fridge before reheating.
Will the Cream Cheese Texture Change After Freezing?
Cream cheese can become slightly grainy or separated after freezing, but in this casserole, it’s blended with heavy cream and sweetened condensed milk, which helps maintain a smooth texture even after freezing. You may notice a very slight change, but once reheated, most people won’t notice a difference, especially with the rich custard and soft brioche bread. For best results, reheat gently and serve with fresh whipped cream or lime zest to bring it back to life!

Key Lime Cheesecake French Toast Casserole
Ingredients
- 1 loaf brioche bread cut into 1-inch cubes
- 1 cup whole milk
- 2 1/4 cups heavy cream divided
- 14 oz can sweetened condensed milk divided
- 2 tbsp cornstarch
- 1/2 tsp baking powder
- 1/2 tbsp pure vanilla extract
- 1/4 tsp salt
- 8 oz cream cheese softened
- 1/4 cup + 1/3 cup key lime juice
- Whipped cream
- Lime zest
- Lime slices
Method
- Grease a 9×13 baking dish and spread the cubed brioche inside.
- In a large bowl, whisk together the milk, 1½ cups of heavy cream, all but 1/3 cup of the sweetened condensed milk (set the 1/3 cup portion aside), cornstarch, baking powder, vanilla, salt, and 1/4 cup of key lime juice until fully combined. Slowly and evenly pour the mixture over the cubed brioche, making sure all the pieces are well-saturated.
- In a separate bowl, whisk together 3/4 cup heavy cream, the reserved 1/3 cup sweetened condensed milk, softened cream cheese, and 1/3 cup key lime juice until thick and creamy. Drop spoonfuls of the cheesecake mixture over the casserole, gently pressing them into the bread to create creamy pockets throughout.
- Cover with aluminum foil and refrigerate overnight (or bake right away).
- Preheat oven to 350°F. If chilled overnight, let sit at room temp for 20–30 minutes. Bake covered for 20 minutes, then uncover and bake another 25 minutes until golden.
- Let cool slightly, then top each slice with whipped cream, lime zest, and lime slices.
