French Toast Casserole Easy Ingredients

For the Base

  • Large eggs – 6; these are essential for creating a rich, custardy texture in the casserole.
  • Whole milk – 2 cups; adds creaminess that enhances the flavor of this French Toast Casserole Easy.

For the Flavoring

  • Pure vanilla extract – 2 tsp; this ingredient infuses the dish with warm, inviting aroma.
  • Ground cinnamon – 1 tbsp; it gives a hint of spice that elevates the comfort food experience.
  • Light brown sugar – 1 cup; adds sweetness and a touch of caramel flavor, balancing the richness of the milk and eggs.

For the Moisture

  • Melted butter – 1/4 cup; this creates a luscious richness, ensuring your casserole is crispy at the edges yet soft inside.

With these simple yet key ingredients, you’re set to create the most comforting and delicious French Toast Casserole Easy!

How to Make French Toast Casserole

  1. Preheat your oven to 350°F (175°C). While it’s warming up, take a moment to grease your 9×13-inch baking dish so your casserole doesn’t stick!

  2. Whisk together the eggs, milk, vanilla extract, cinnamon, and brown sugar in a large bowl until frothy. This mixture creates the custard that will soak into the bread, so get it nice and blended!

  3. Layer half of the cubed bread in the baking dish. Pour half of the custard mixture over the bread, ensuring each piece gets a taste of the delightful goodness.

  4. Add toppings if desired, such as fresh berries or nuts for that extra touch. Then layer the remaining bread cubes on top, followed by the rest of the custard mixture. Press lightly down to soak up all that rich flavor.

  5. Cover the baking dish with aluminum foil and pop it in the oven for 30 minutes. After that, remove the foil and bake for an additional 15-20 minutes. You’re looking for a golden, puffed-up top!

  6. Cool slightly before lovingly slicing into squares. Serve warm and watch everyone’s eyes light up with delight!

Optional: Dust with powdered sugar for an extra sweet touch!

Helpful Tricks for French Toast Casserole

  • Use Stale Bread: Ensure your bread is stale or slightly dried out for the best absorption of the custard mixture, preventing a soggy casserole.

  • Press Gently: After layering, lightly press the bread into the custard mixture to ensure every piece is soaked without breaking it apart.
