How do you make single-serve French toast casserole?

It’s simpler than you think! Start by whisking together an egg, milk, vanilla, cinnamon, and a touch of brown sugar. Dice one slice of your favorite bread and half an apple, then mix everything in a buttered ramekin. Let it soak for 10–15 minutes or overnight for deeper flavor. Bake at 350°F until golden and set.

Can you put French toast casserole in a ramekin?

Yes, and it’s the best way to make a personal portion. A standard 6–8 oz ramekin is ideal for a single-serve apple French toast casserole. It bakes evenly, holds its shape, and creates a golden, crisp top with soft, custardy layers underneath. We use ramekins often, like in our BLT cottage cheese bowl .

Can French toast casserole be made in advance?

Absolutely. In fact, prepping it the night before enhances the flavor. Simply assemble your single-serve apple French toast casserole, cover, and refrigerate. The bread absorbs the custard overnight, making the final texture smoother and richer. Then, bake fresh in the morning. If you're into meal prep, our loaded breakfast casseroles follow the same process.

How do you keep French toast casserole from being soggy?

Use slightly stale or toasted bread for better structure. Also, ensure your egg-to-milk ratio isn’t too heavy on liquid—too much milk causes sogginess. Let it bake fully until the center is set. A crisp top is a good sign! We follow this tip in our classic French toast recipes too.

Can you freeze French toast casserole after cooking?

Yes! Once baked and fully cooled, wrap the casserole in plastic and foil or use a freezer-safe container. It stores well for up to two months. Thaw overnight and reheat in the oven or microwave. This single-serve approach makes freezing and reheating super practical, just like our crispy French toast sticks .

What is the best bread for French toast casserole?

Brioche, challah, or thick-cut white bread work best—they soak in the custard without falling apart. Day-old bread is ideal for absorbing flavor while keeping structure. For more creative takes using hearty breads, check out our cottage cheese breakfast quiche .
