Step-by-Step Cooking Instructions
Making this casserole is as easy as mixing, layering and baking. Here is a step-by-step guide to help you prepare your dish from start to finish.
Begin by preheating your oven to 350 degrees Fahrenheit. This ensures that the casserole cooks evenly and turns golden on top.
Cut the bread into small cubes or tear it by hand into bite-sized pieces. This helps it soak up the egg mixture better and creates a nice texture once baked.
Use a little butter or cooking spray to grease a medium-sized baking dish. This prevents sticking and makes cleanup easier.
Place half of the bread in the bottom of the dish. Add a layer of cooked vegetables or meat and sprinkle half of the shredded cheese on top. Then add the remaining bread and the rest of the cheese.
In a separate bowl, whisk together the eggs, milk, salt, pepper and herbs. Make sure everything is well combined so that the seasonings are evenly distributed.
Slowly pour the egg mixture over the layers in the baking dish. Press down gently with a spatula to help the bread absorb the liquid. Let it sit for about 10 to 15 minutes.
Place the dish in the oven and bake for 35 to 40 minutes. The top should be golden brown and the center set. You can check by inserting a knife or toothpick in the middle. If it comes out clean, it is ready.
Allow the casserole to cool for about 5 to 10 minutes before serving. This helps it firm up a bit and makes it easier to slice.
Tips for Customizing the Recipe

One of the best parts about this toast casserole is how easy it is to customize. Here are a few ways to make it your own.
If you like a richer flavor, try adding a few tablespoons of cream to the milk mixture. You can also add a spoonful of mustard or a sprinkle of garlic powder for a savory twist.
Want to make it vegetarian? Skip the meat and load it with more vegetables like kale, zucchini or tomatoes. You can also use plant-based cheese to make it dairy-free.
For a meaty version, add cooked bacon, ground beef or diced chicken. Make sure any meat you use is fully cooked before adding it to the dish.
Like things spicy? Add a pinch of chili flakes or drizzle hot sauce on top before serving.
You can also prepare the casserole the night before and bake it in the morning. Just cover and refrigerate overnight, then pop it into the oven the next day.
