Easy Low-Sodium French Toast Casserole
This gentle, make-ahead breakfast turns a few simple ingredients into a soft, custardy casserole you can bake in the morning. It soaks overnight for extra tenderness and keeps salt and sugar low for a lighter, digestion-friendly start to the day.

Portion size, soft texture, and low added salt make this dish gentle on digestion. You can make the custard looser for a creamier result or chop the finished casserole into small pieces for easier chewing.
Ingredients You’ll Need

- 3 slices low-sodium sandwich bread, torn or cut into 1-inch cubes
- 1 large egg, 1/2 cup low-fat or lactose-free milk, 1 teaspoon vanilla extract, and 1/2 teaspoon ground cinnamon
- 1 teaspoon maple syrup or honey optional, 1 tablespoon unsalted butter or 1 teaspoon neutral oil for greasing, and fresh fruit or unsweetened applesauce for serving
Serve with plain yogurt, soft fruit, or unsweetened applesauce for a gentle, low-sugar option.
Step-by-Step Recipe

- Grease a small baking dish about 6 by 6 inches with the unsalted butter or oil and add the bread cubes in an even layer.
- Whisk the egg, milk, vanilla, cinnamon, and maple syrup until smooth. Pour the custard evenly over the bread, press gently, cover, and refrigerate at least 4 hours or overnight for a custardy texture.
- When ready to bake, preheat the oven to 350 F and let the dish sit 10 minutes. Bake uncovered 25 to 30 minutes until lightly golden and set, rest 5 minutes, then serve with fruit or yogurt.

FAQ
Can I make this without eggs?▶
Yes. For an egg free version, mix 3/4 cup unsweetened plant milk with 2 tablespoons cornstarch until smooth and use in place of the egg mixture. The texture will be slightly different but still soft.
Can I skip the overnight soak?▶
You can soak for at least 4 hours, but overnight gives the best custardy softness. For a quick version let it sit 30 minutes before baking and expect a firmer texture.
