How to Make Monte Cristo Breakfast Casserole
-
Preheat your oven to 350°F (175°C) and grease a baking dish to prevent sticking. This step ensures your casserole will bake evenly and come out beautifully.
-
Cut the bread into cubes and layer half of them at the bottom of your prepared baking dish. This forms a solid base to soak up all that delicious egg mixture.
-
Layer the sliced ham on top of the bread, followed by half of the shredded Swiss cheese. Feel free to be generous with the cheese—it adds a creamy, tasty finish!
-
Whisk together the eggs, milk, maple syrup, mustard, salt, and pepper in a large bowl until well combined. This mixture is the heart of your casserole, binding all the elements beautifully.
-
Pour half of the egg mixture evenly over the first layers of bread, ham, and cheese. Watch as it gets absorbed; this is where the magic begins!
-
Repeat layering with the remaining bread, ham, and cheese. Pour the rest of the egg mixture on top, ensuring everything is well coated for maximum flavor.
-
Cover with foil and bake for 30 minutes. Uncover and bake for an additional 15-20 minutes until the casserole is set and golden brown. The edges should be slightly crispy, and the center fluffy.
