Keto Caramel Bottom French Toast Bake is a rich, comforting breakfast casserole that combines the warm flavors of cinnamon French toast with a buttery sugar-free caramel layer baked underneath. This low-carb version recreates the indulgent taste of classic overnight French toast bakes while using keto-friendly bread and sweeteners to keep carbohydrates low. The result is a soft, custardy center with a gooey caramelized bottom that becomes beautifully golden when flipped or served warm.
The caramel layer is the true highlight of this recipe. Made with butter, brown keto sweetener, and a touch of cinnamon, it melts into a sticky, decadent sauce during baking. As the casserole cooks, the bread absorbs the creamy egg mixture while the caramel bubbles underneath, creating a dessert-like breakfast experience without traditional sugar.
This dish is ideal for holidays, brunch gatherings, weekend breakfasts, or meal prep because it can be assembled ahead of time and baked fresh in the morning. Keto bread works wonderfully in this recipe because it absorbs the custard mixture while maintaining structure. Every bite is filled with warm cinnamon flavor, creamy texture, and buttery caramel richness.
Despite tasting incredibly indulgent, this keto French toast bake remains low in net carbs and high in satisfying fats. It pairs perfectly with coffee, crispy bacon, or sugar-free whipped cream. Whether served for family brunch or as a cozy breakfast treat, this casserole delivers all the comfort of classic French toast while supporting ketogenic goals.

- 1/2 cup brown keto sweetener
- 1 tsp cinnamon
- 1 tsp vanilla extract
For the French Toast Bake
- 1 loaf keto bread, cubed
- 6 large eggs
- 1 cup heavy cream
- 1/2 cup unsweetened almond milk
- 1/4 cup powdered erythritol
- 1 tsp vanilla extract
- 1 tsp cinnamon
- Pinch of salt
Optional Toppings
- Sugar-free syrup

Instructions
Step 1: Preheat Oven
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
Step 2: Make the Caramel Layer
In a saucepan over medium heat, melt butter and stir in brown keto sweetener, cinnamon, and vanilla extract. Cook for 2–3 minutes until smooth and bubbling.
Step 3: Add Caramel to Dish
Pour the caramel mixture evenly into the bottom of the prepared baking dish.
Step 4: Add Bread
Spread cubed keto bread evenly over the caramel layer.
Step 5: Prepare Egg Mixture
In a large bowl, whisk together eggs, heavy cream, almond milk, powdered erythritol, vanilla, cinnamon, and salt.
Step 6: Assemble
Pour the egg mixture evenly over the bread cubes. Gently press bread down so it absorbs the custard.
Step 7: Bake
Bake for 35–40 minutes until the top is golden and the center is set.
Step 8: Cool Slightly
Allow the casserole to rest for 5–10 minutes before serving so the caramel thickens slightly.
