This light and fluffy cottage cheese French toast casserole is a high-protein, low-carb breakfast that’s easy to make, delicious, and perfect for busy mornings.

This cottage cheese French toast casserole is light, fluffy, and just the right amount of sweet, like a cross between French toast and bread pudding. And you’d never guess it’s actually healthy, with its sweet, creamy base and cozy cinnamon topping. Add a drizzle of sugar-free syrup or whipped cream, and it’s a yummy breakfast treat!

It’s also high in protein and low in carbs since it’s made with low-fat cottage cheese, eggs, almond milk and Hero Bread (a zero net-carb, keto-friendly bread). Unlike regular French toast casseroles, this one won’t leave you feeling sluggish. It’s light yet filling, balanced and guilt-free.

Best of all, it’s super easy to make. Just blend, pour and bake — no fuss! It also reheats well, so you can make it ahead for quick breakfasts during the week. Simple, tasty and satisfying!

Key Ingredients

Hero Bread: This is a new favorite keto bread at our house! You can find it at many grocery stores (we get ours at Kroger) in both white and seeded varieties (both are great). It’s high in fiber, has zero net carbs, is low in calories, and even contains some protein. Just a heads-up: we haven’t tested this casserole with other low-carb breads, so results may vary if you use a different one.

Low-fat cottage cheese: We use a low-fat cottage cheese (2% milkfat) to keep the protein percentage high. That said, you could also use a full-fat cottage cheese since it only slightly reduces the protein percentage.

Eggs: Help bind everything together while adding structure and fluffiness.

Sugar-free sweetener: We like to sweeten with Lakanto monk fruit sweetener (with erythritol). However, you can sweeten with another sweetener of preference. Just be sure to check a sweetener conversion chart.

Cinnamon: Adds warmth and a cozy, classic French toast flavor. Feel free to adjust the amount based on your preference.

Vanilla extract: Enhances the sweetness and adds depth to the flavor.

How to Make

Get started: Preheat oven to 350°F. Grease an 8×8 baking dish with cooking spray or butter. Cube the keto bread and spread it evenly in the baking dish.

Blend cottage cheese: In a food processor or blender, pulse together cottage cheese, eggs, almond milk, sugar-free sweetener, vanilla, cinnamon, and salt until smooth.

Soak the bread: Pour the blended mixture over the cubed bread, making sure every piece is coated.

Add toppings and bake: Mix ½ teaspoon cinnamon with ½ teaspoon sugar-free sweetener, then sprinkle over the casserole. Bake for 25 minutes, or until golden brown and set in the center.

Variations

Berry bliss: Mix in fresh or frozen berries like blueberries or raspberries.

Pumpkin spice: Swap cinnamon for pumpkin spice for a fall-inspired twist.

Chocolate chip: Stir in a handful of sugar-free chocolate chips before baking.
Nutty crunch: Add chopped pecans, walnuts, or slivered almonds for texture.

How to Store

Store the casserole in the fridge for up to 4 days in an airtight container. To reheat, microwave a slice for 30 to 60 seconds.
