Preheat the oven to 375°F (190°C). Line a large baking sheet with parchment paper.
Add the eggs, cottage cheese, egg whites, vanilla extract, cinnamon, and salt to a blender. Blend until completely smooth and creamy, with no visible cottage cheese curds.
2 large eggs, ½ cup cottage cheese, ¼ cup liquid egg whites, 1 tsp vanilla extract, ½ tsp ground cinnamon, 1 pinch salt
Pour the custard into a shallow dish. Briefly dip each slice of bread into the mixture, coating both sides for approximately 2–3 seconds per side. Allow excess custard to drip off to prevent the bread from becoming overly saturated.
8 slices bread
Arrange the coated bread slices in a single layer on the prepared baking sheet, leaving space between each slice. Use two baking sheets if needed. Bake for approximately 12–18 minutes, carefully flipping halfway through, until lightly golden brown and the custard is fully set. Cooking time may vary depending on the thickness of the bread.
Divide the French toast between four plates, serving two slices per person. Top with fresh berries, Greek yogurt, and maple syrup.
1 cup mixed berries, ½ cup Greek yogurt, 1 tbsp Maple syrup or sugar-free syrup
